Description

The present invention belongs to the technical field of finishing of bearing rotating bodies with respect to a grinding disc set for finishing the rolling surface of a bearing roller, grinding equipment and a grinding method.

Roller bearings (cylindrical roller bearings and conical roller bearings) are widely used in a variety of rotating machines. The shape accuracy and dimensional matching of the rolling surface of bearing rollers (cylindrical rollers and conical rollers), which are one of the important parts of roller bearings, have a great influence on the performance of roller bearings. Currently known procedures for processing the rolling surface of bearing rollers are blank forming (turning, cold pressing or rolling), roughing (flexible polishing of the rolling surface), heat treatment, and semi-finishing (rolling surface). Rigidity polishing)
, And finishing. The main process of finishing the rolling surface of known bearing rollers is super-finishing.

In super-finishing, a fine-grained oil grindstone is used as an abrasive, and a low pressing force is applied to the machined surface of the workpiece with the oil grindstone to reciprocate vibration and low-speed feed with high speed and fine amplitude along the machined surface of the workpiece. This is a finishing method that cuts a small amount by exercising.

Currently, it is common to use a centerless through super-finishing method for finishing the rolling surface of a cylindrical roller. The machined part of the equipment consists of a pair of super-finishing guide rolls that are tilted in different directions and one (or one set) of super-finishing heads equipped with an oil grindstone, and the cylindrical rollers are made of guide rolls. While being supported and driven and rotating
The ultra-finishing head presses the oil grindstone against the rolling surface of the cylindrical roller with a low pressing force, and the oil grindstone is the cylindrical roller. High-speed, fine-amplitude reciprocating vibration is performed along the surface dividing line of the rolling surface, and the rolling surface of the cylindrical roller is finished. In centerless through super-finishing, a cylindrical roller of the same batch penetrates the machining area and is super-finished with an oil grindstone.

In addition, there is also a centerless notch super-finishing method, in which the machined part of the equipment is a pair of super-finishing guide rolls arranged in parallel and one (or one set) of super-finishing with an oil grindstone. It consists of a finishing head, and the cylindrical roller is supported and driven by a guide roll to rotate, and the super-finishing head presses the oil grindstone against the rolling surface of the cylindrical roller with a low pressing force, and the oil grindstone is a cylindrical roller. The rolling surface of the cylindrical roller is finished by performing low-speed feed motion and reciprocating vibration with high speed and fine amplitude along the trajectory aligned with the surface dividing line of the rolling surface. In the centerless notch super-finishing process, cylindrical rollers of the same batch enter the processing area one by one and are super-finished with an oil grindstone.

The following two technical defects exist in the super-finishing method of the rolling surface of the above two cylindrical rollers. One is that the change over time in the wear state of the grindstone and the guide roll during machining is disadvantageous in improving the shape accuracy and dimensional accuracy of the rolling surface of the cylindrical roller, and the other is super-finishing. The equipment processes only one (or a small number) of cylindrical rollers at the same time, and the amount of material removed from the rolling surface of the cylindrical roller to be machined is affected by the difference in the diameter of the rolling surface of the cylindrical rollers of almost the same batch. Therefore, when the rolling surface of the cylindrical roller is machined with a super-finishing facility, it is difficult to improve the variation in the diameter of the rolling surface of the cylindrical roller to be machined. The above two technical defects limit the improvement of the shape accuracy and dimensional matching of the rolling surface of the cylindrical roller to be machined.

Currently, there are also the following devices (equipment) and methods for finishing the rolling surface of a cylindrical roller.

However, there is a gap between the grinding rolls, a salary tank is attached above the gap, an upper pressing plate is provided above the salary tank, and a pressure hammer is added above the upper pressing plate to perform upward pressing. The contact surface between the plate and the roller is arcuate. Due to the difference in linear velocity between the two grinding rolls, the cylindrical roller and the grinding roll slide relative to each other. By adjusting the vertical and horizontal angles of the grind roll, the rollers are driven to be fed along the axial direction. The grinding roll grinds the surface of the roller while driving the cylindrical roller.

It is characterized in that the abrasive material processes the cylindrical surface of the roller.

In both of the above two devices, the cylindrical roller is supported by two drive rolls and driven forward, and an abrasive for processing the cylindrical surface of the cylindrical roller is provided vertically above the cylindrical roller in the forward direction. All cylindrical rollers pass through the machining area in sequence as they are machined. Such equipment, like superfinishing equipment, has the above two technical deficiencies.

When grinding, a cylindrical roller is placed in the hole of the holding frame and a pushing force is applied to the top grinding disc, the workpiece is located between the top grinding disc and the bottom grinding disc and comes into contact with the top and bottom grinding disc. The upper grinding disc, lower grinding disc, outer ring gear and eccentric wheel are rotationally driven, and the workpiece is driven by the vertical grinding disc to rotate, while the holding frame is driven by the drive of the upper grinding disc and the lower grinding disc to cycle around the upper grinding disc and the lower grinding disc. Exercise.

The Chinese patent gazette of publication number CN103252166A discloses a method for machining a cylindrical part outer circle based on eccentric pressurization on an upper disc, wherein the machining apparatus includes a top grinding disc, a holding frame and a bottom grinding disc. There is. The top grinding disc is located above the bottom grinding disc, the holding frame is located between the top grinding disc and the bottom grinding disc, and the rotation axis of the holding frame and the rotation axis of the bottom grinding disc are installed coaxially, and the top grinding is performed. There is a predetermined offset between the axis of rotation of the disk and the axis of rotation of the holding frame. During processing, the load device acts eccentrically on the cylindrical part via the upper grinding disc, and the outer circle of the cylindrical part is processed by the combination of the flat surface of the upper grinding disc and the lower grinding disc and the abrasive.

The Chinese patent gazette of publication number CN105798765A discloses a four-plane reciprocating grinding method and device for a cylindrical roller, which is provided with a mounting frame that is rotationally driven by a power source within the frame. The outer wall in the circumferential direction of the mounting frame is provided with a plurality of mounting tanks for mounting the cylindrical roller, and the frame is provided with a grinding plate for gap fitting with the cylindrical roller corresponding to the mounting frame. do. When used, a cylindrical roller is attached to the mounting frame, and the mounting frame is rotated to grind a plurality of cylindrical rollers on the grinding plate at the same time.

However, due to the sealing characteristics of this processing equipment (equipment), such equipment (equipment) does not have mass production capacity.

The Chinese patent gazettes of publication numbers CN104493689A and CN104493684A include
Double disc type grinding discs with linear grooves for cylindrical parts, grinding equipment and grinding methods are disclosed, the equipment including a workpiece push device, a workpiece transfer device and a grinding disc device. The grinding disc device includes the first and second grinding discs, the two grinding discs rotate relative to each other, the working surface of the first grinding disc is a flat surface, and the second grinding disc and the first grinding disc face each other. A set of radial linear grooves is provided on the surface, both sides of the linear groove serve as the working surface of the second grinding disk, and the cross-sectional contour of the working surface of the second grinding disk is arcuate or V-shaped. It has a V-shape with an arc, and the range of the angle between the normal plane at the contact point between the workpiece to be machined and the linear groove or the midpoint of the contact arc and the reference surface of the linear groove is 30 to 60 °.
One end of the linear groove near the center of the second grinding disc serves as a push port, the other end of the linear groove serves as a discharge port, and the workpiece push device is inserted into the central through hole of the second grinding disc. Includes a body and multiple material push means and storage tanks installed and attached to the body.

When grinding the cylindrical surface of a cylindrical roller using the equipment, on the one hand, the cylindrical roller can cycle inside and outside the grinding disc, thus providing mass production capacity, and on the other hand, in the field of grinding. , The equipment can process a large number of cylindrical rollers at the same time by comparing them.
As described above, the material of the cylindrical surface of the large-diameter cylindrical roller is largely removed, which is advantageous for improving the dimensional matching of the cylindrical surface of the cylindrical roller.

However, in the conventional double disk type grinding disk with a linear groove, the number of linear grooves that can be installed in the second grinding disk is small due to the limitation due to the diameter of the central through hole of the second grinding disk. The improved form is as follows. The working surface of the first grinding disc is a conical surface, and a set of radial linear grooves is provided on the facing surface between the second grinding disc and the working surface (conical surface) of the first grinding disc. On the other hand, under the condition that the outer diameter of the second grinding disc and the length of the linear groove are constant, the diameter of the central through hole is increased by adjusting the conical apex angle of the conical surface of the first grinding disc. Increase the number of linear grooves in the second grinding disc. As the number of linear grooves in the second grinding disc increases, the number of cylindrical rollers that can be subjected to grinding increases, and thus the efficiency and dimensional matching of the cylindrical surface of the cylindrical roller of the cylindrical roller. It is advantageous for improvement. On the other hand,
Compared with the surface grinding disk, the conical surface grinding disk has an advantage of self-centering and is advantageous in improving the dimensional matching of the cylindrical surface of the cylindrical roller.

In addition, when grinding a cylindrical roller using a conventional double disc grinding disc with a linear groove, the workpiece push device keeps the cylindrical roller to be machined axially fed in the linear groove. Therefore, it is necessary to continuously apply an axial thrust to the cylindrical roller to be machined, and the axial push capability of the workpiece push device is highly required. The improved form is as follows. The flat work surface of the first grinding disc is installed on the spiral groove type work surface, and the workpiece push device only needs to push the cylindrical roller to be processed to the intersection of the linear groove and the spiral groove, and thereafter. Axial feed of the cylindrical roller to be machined is performed by spiral push by the spiral groove work surface.

Further, in the actual grinding process, "under the conditions that the workpiece to be machined can self-turn during the grinding process, the pressure of the grinding process, and the grinding lubrication conditions, the material between the work surface material of the first grinding disk and the material of the workpiece to be processed is It is difficult to realize that the friction coefficient is larger than the friction coefficient between the work surface material of the second grinding disc and the material of the workpiece to be machined. " It is difficult to select the combination of the working surface materials of the first grinding disc and the second grinding disc provided.

Currently, a centerless through super-finishing method is generally used for finishing the rolling surface of a conical roller. The machined part of the equipment consists of a pair of super-finished spiral guide rolls with spiral laces and one (or one set) super-finished head equipped with an oil grindstone, and the conical rollers are supported and driven by the guide rolls. While rotating, a low-speed feed motion is performed along the trajectory aligned with the surface dividing line of the rolling surface of the conical roller, and the super-finishing head presses the oil grindstone against the rolling surface of the conical roller with low pressing force. The oil grindstone reciprocates at high speed and with a slight amplitude along the surface dividing line of the rolling surface of the conical roller, and finishes the rolling surface of the conical roller. In centerless through super-finishing, conical rollers of the same batch pass through the machining area in sequence and are super-finished with an oil grindstone.

In addition, there is also a centerless notch super-finishing method, in which the machined part of the equipment is a pair of super-finishing guide rolls installed in parallel and one (or one set) of super-finishing with an oil grindstone. It consists of a finishing head, and the conical roller is supported and driven by a guide roll to rotate, and the super-finishing head presses the oil grindstone against the rolling surface of the conical roller with low pressing pressure, and the oil grindstone is a conical roller. The rolling surface of the conical roller is finished by performing low-speed feed motion and reciprocating vibration at high speed and fine amplitude according to the locus aligned with the surface dividing line of the rolling surface. In the centerless notch super-finishing process, conical rollers of the same batch enter the processing area one by one and are super-finished with an oil grindstone.

There are the following two technical methods in the super-finishing method for the rolling surface of the above two conical rollers. One is that the change over time in the wear state of the grindstone and the guide roll during machining is disadvantageous in improving the shape accuracy and dimensional accuracy of the rolling surface of the conical roller, and the other is super-finishing. The equipment processes only one (or a small number) conical rollers at the same time, and the amount of material removed from the rolling surface of the conical roller to be machined is affected by the difference in the diameter of the rolling surface of the conical rollers in almost the same batch. Therefore, when the rolling surface of the conical roller is machined with a super-finishing facility, it is difficult to improve the variation in the diameter of the rolling surface of the conical roller to be machined. The above two technical defects limit the improvement of the shape accuracy and dimensional matching of the rolling surface of the conical roller to be machined.

The Chinese Patent Publication No. CN1863642A discloses a method for processing a conical roller, and the conical roller is characterized in that the roller surface is finished by a method of barrel polishing or drum polishing. There is inaccuracies in the removal of the roller surface material during processing, and the method cannot improve the dimensional accuracy and diameter variability of the rollers.

Large diameter bearing rollers can remove much of the rolling surface material, and small straight bearing rollers can remove a small amount of rolling surface material, thereby rolling surfaces of cylindrical and conical rollers. It is possible to improve the shape accuracy and dimensional matching of the bearing, improve the processing efficiency of the rolling surface of the cylindrical roller and the conical roller, and reduce the processing cost.

In order to solve the above technical problems, the grinding disc set for finishing the rolling surface of the bearing roller according to the present invention includes a pair of coaxial first grinding discs and a second grinding disc, and is a first grinding disc.

At the time of grinding, a cylindrical roller corresponds to each joint of the spiral groove of the second grinding disk and the linear groove of the first grinding disk, and is formed along the linear groove in the linear groove of the first grinding disk. Alternatively, bearing rollers to be machined, which are conical rollers, are distributed, and the area surrounded by the linear groove work surface of the first grinding disk and the spiral groove working surface of the second grinding disk corresponds to each joint and is ground. It becomes a machined area, and the rolling surface of the bearing roller to be machined comes into contact with each of the straight groove work surface and the spiral groove work surface, and the action of friction drive and pressing by the spiral groove work surface causes the machined bearing roller to have its own axis. While rotating around, it translates along the straight groove, and the rolling surface of the bearing roller to be machined and the working surface of the straight groove slide relative to each other, and the rolling surface of the bearing roller to be machined is ground.

The baseline passes through the center of curvature of the contour of the axial perpendicular cross section and is located within the axial cross section of the first grinding disc. During grinding, the axis of the cylindrical roller to be machined is located in the central plane of the straight groove work surface, and the rolling surface of the cylindrical roller to be machined comes into surface contact with the straight groove work surface to form a cylindrical machine. The axis of the shaped roller overlaps with the straight groove baseline,

The central plane of the groove working surface is a plane including the contour symmetric line of the linear groove scanning surface and the linear groove baseline, and the straight groove baseline is located in the axial cross section of the first grinding disk. The central plane of the straight groove work surface overlaps with the axis-included cross section of the first grinding disk including the straight groove baseline, and during grinding, the axis of the conical roller to be machined is within the central plane of the straight groove work surface. Positioned, the rolling surface of the conical roller to be machined is in line contact with each of the bisymmetrical sides of the straight groove work surface, and the straight groove baseline is in the mapping on the axis of the rolling surface of the conical roller to be machined. Passing through the points, if the semi-conical angle of the conical roller to be processed is φ, and the deviation angle between the axis of the conical roller to be processed and the linear groove baseline is γ, sin φ = s.

Step 5 of injecting the grinding fluid into the grinding area,
1) In the case of a cylindrical roller, the second grinding disc is closer to the first grinding disc along its axis, and the rolling surface of the cylindrical roller to be machined in the grinding area is a linear groove of the first grinding disc. In surface contact with the working surface and in line contact with the first working surface of the second grinding disc spiral groove, in the case of a conical roller, the second grinding disc is closer to the first grinding disc along its axis. , The rolling surface of the conical roller to be machined in the ground area is in line contact with the bisymmetric side surface of the linear groove work surface of the first grinding disc and the first working surface of the spiral groove of the second grinding disc, respectively, to form a conical shape to be machined. To make the large-diameter end ball base surface or the large-diameter end fillet or the small-diameter end fillet of the roller in line contact with the second working surface of the second grinding disk spiral groove.
2) An initial working pressure of 0.5 to 2N on average is applied to each bearing roller to be machined in the ground area, and the bearing roller to be machined is subjected to frictional drive by the spiral groove work surface of the second grinding disk. While continuously rotating around the axis, a linear feed motion is performed along the linear groove baseline of the first grinding disk by the continuous pressing action of the spiral groove work surface, and the rolling surface of the bearing roller to be machined is the first. Step 6 including starting to be ground by the straight groove working surface of the grinding disk and the first working surface of the second grinding disk spiral groove, and
As the grinding process is performed stably, the working pressure is gradually increased to the normal working pressure of 2 to 50 N for each bearing roller to be machined in the grinding area, and the bearing roller to be machined is as in step 6. The contact relationship between the linear groove work surface of the first grinding disc and the spiral groove working surface of the second grinding disk, the continuous rotational movement around its own axis, and the linear feed movement along the straight groove baseline are maintained and rolled. Step 7 where the surface is continuously ground by the straight groove working surface of the first grinding disk and the first working surface of the second grinding disk spiral groove,
After grinding for a predetermined time, the bearing roller to be machined is sampled and inspected, and the quality, shape accuracy and dimensional matching of the surface of the rolling surface of the bearing roller to be sampled and inspected meet the technical requirements. If not, the grinding process of this step is continued, and if the quality, shape accuracy and dimensional matching of the surface quality, shape accuracy and dimensional matching of the rolling surface of the bearing roller to be sampled and inspected meet the technical requirements, step 9 is entered. When,
The working pressure is gradually reduced to zero, the operation of the roller loading means, the roller transport system and the roller organizing means is stopped, the relative rotation speed between the first grinding disk and the second grinding disk is adjusted to zero, and the grinding area. We propose a grinding method for finishing the rolling surface of a bearing roller, which includes step 9 of stopping the injection of grinding fluid into the second grinding disk and returning the second grinding disk to a non-working position along its axis.

Further, in the above-mentioned grinding method of the present invention, the grinding disk set of the grinding equipment used is the above-mentioned magnetic grinding disk set, which is used for finishing the rolling surface of the bearing roller made of a ferromagnetic material. As a difference of
In step 3, the roller demagnetization device, the roller transport system, the roller organizing means, and the roller carry-in means are activated, and the carry-in speed of the roller carry-in means is adjusted so as to match the relative rotation speed between the first grinding disk and the second grinding disk. Adjust and adjust the transfer speed of the roller transfer system and the arrangement speed of the roller rearranging means so as to match the carry-in speed of the roller carry-in means, whereby the bearing roller to be machined is placed between the first grinding disk and the second grinding disk. Establishing a cycle of collection, transfer, arrangement and delivery by the roller cycle system, being sent along the straight line of the straight groove baseline between
In step 6,
1) The annular magnetic structure inside the second grinding disc substrate enters the working state, and in the case of a cylindrical roller, the second grinding disc further approaches the first grinding disc along its axis and is covered in the grinding area. The rolling surface of the machined cylindrical roller is in surface contact with the linear groove working surface of the first grinding disc and in line contact with the first working surface of the spiral groove of the second grinding disc. In the case of a conical roller, the second grinding is performed. The disc is closer to the first grinding disc along its axis, and the rolling surfaces of the conical rollers to be machined in the grinding area are bisymmetrical sides of the linear groove working surface of the first grinding disc and the second grinding disc spiral, respectively. Make line contact with the first working surface of the groove so that the large-diameter ball base surface or large-diameter end fillet or small-diameter end fillet of the conical roller to be machined makes line contact with the second working surface of the second grinding disc spiral groove. To do and
2) An initial working pressure of 0.5 to 2N on average is applied to each bearing roller to be machined in the ground area to adjust the magnetic field strength of the annular magnetic structure with respect to the rotation of the bearing roller to be machined around its own axis. The slip friction drive torque of the spiral groove work surface of the 2nd grinding disc should be larger than the slip friction resistance torque of the straight groove work surface of the 1st grinding disc with respect to the rotation of the bearing roller to be machined around its own axis. By the bearing roller to be machined,
While being continuously rotationally driven around its own axis, the continuous pressing action of the spiral groove work surface causes a linear feed motion along the linear groove baseline of the first grinding disc, and the rolling surface of the bearing roller to be machined is Grinding begins with the straight groove work surface of the first grinding disc and the first working surface of the second grinding disc spiral groove.
In step 9,
The working pressure is gradually reduced to zero, the operation of the roller loading means, the roller transport system and the roller organizing means is stopped, the relative rotation speed between the first grinding disk and the second grinding disk is adjusted to zero, and the annular magnetic structure. To the non-working state, stop the operation of the roller demagnetizer,
The injection of the grinding fluid into the grinding area is stopped, and the second grinding disk returns to the non-working position along its axis.

In the grinding method of the present invention, the magnetic structure is installed inside the second grinding disc of the grinding disc set of the grinding equipment used, when the workpiece bearing roller of the ferromagnetic material is ground by the fixed abrasive grain grinding method. , A magnetic structure is installed inside the second grinding disk, and by adjusting the magnetic field strength of the magnetic structure, the second grinding disk has a rotation with respect to the rotation of the work bearing roller of the ferromagnetic material around the axis itself. The slip friction drive torque of the spiral groove work surface is set to be larger than the slip friction resistance torque of the linear groove work surface of the first grinding disk with respect to the rotation of the work bearing roller of the ferromagnetic material around the axis itself. When the work bearing roller made of the ferromagnetic material is continuously rotationally driven around its own axis 1 and
When grinding a bearing roller made of a ferromagnetic material by the free abrasive grain grinding method, a magnetic structure is installed inside the second grinding disk, and the bearing roller made of the ferromagnetic material is rotated around its own axis. The sliding friction drive torque generated by the spiral groove work surface of the second grinding disc is increased, and the continuous rotation of the bearing roller to be machined made of the ferromagnetic material around the axis itself is a straight line of the first grinding disc. The case 2 is included in which the material of the groove work surface and the material of the spiral groove work surface of the second grinding disk are not restricted by matching.

In the grinding method of the present invention, prior to the first use of the first grinding disc and the second grinding disc, the linear groove work surface of the first grinding disc and the linear groove working surface of the first grinding disc are used by using a bearing roller having the same geometric parameters. Run-in is performed on the spiral groove work surface of the second grinding disc by the same running-in method as the grinding method of the bearing roller to be processed.
In step 8, the bearing rollers to be machined that are involved in running-in are sampled and inspected, and the quality, shape accuracy and dimensional matching of the surface of the rolling surface of the bearing rollers to be sampled and inspected meet the technical requirements. The break-in process goes into step 9, and if not met, step 8 is continued.

Compared with the prior art, the beneficial effects of the present invention are as follows.

In the grinding process, the rolling surface of the bearing roller to be machined is the straight groove of the first grinding disk in each grinding area surrounded by the linear groove working surface of the first grinding disk and the spiral groove working surface of the second grinding disk. In contact with each of the work surface and the spiral groove work surface of the second grinding disc, the bearing roller to be machined rotates around its own axis under the friction drive by the spiral groove work surface of the second grinding disc, and the bearing roller to be machined The rolling surface of the first grinding disk slides relative to the linear groove working surface of the first grinding disk, whereby the rolling surface of the bearing roller to be machined is ground.

The removal of the material on the rolling surface directly leads to the contact stress between the rolling surface and the straight groove work surface, and the high point of the rolling surface of the large-diameter bearing roller to be machined or the rolling surface of the bearing roller to be machined comes into contact with the straight groove work surface. In this case, the contact stress between the rolling surface and the straight groove work surface is large, the amount of material removed from the rolling surface at the contact point is large, and the rolling surface of the bearing roller to be machined or the rolling surface of the bearing roller to be machined is low. When the place comes into contact with the straight groove work surface, the contact stress between the rolling surface and the straight groove work surface is small, and the amount of material removed from the rolling surface at the contact point is small. As a result, a large amount of material is removed at high places on the rolling surface of the bearing roller, a small amount of material is removed at low places, a large amount of material is removed on the rolling surface of the large-diameter bearing roller, and the rolling surface of the small-diameter bearing roller. Now remove the material in a small amount.

Since the straight groove of the first grinding disc and the spiral groove of the second grinding disc are designed to be open,
In grinding, the bearing roller to be machined is fed between the first grinding disc and the second grinding disc along the straight line of the straight groove baseline, and the collection, transfer, arrangement, and carry-in cycle by the roller cycle system. It exists and the original order of the bearing rollers to be machined is broken when going through the roller cycle system.

On the one hand, the openness design of the straight groove of the first grinding disc and the spiral groove of the second grinding disc is extremely suitable for finishing the rolling surface of a large number of bearing rollers, and on the other hand, it is covered when going through the roller cycle system. Due to the out-of-order of the processed bearing rollers, "a large amount of material is removed at high places on the rolling surface of the bearing rollers, a small amount of material is removed at low places, and materials are removed on the rolling surface of large-diameter bearing rollers. To provide the above-mentioned feature of "removing a large amount of material and removing a small amount of material on the rolling surface of a bearing roller with a small diameter", thereby improving the shape accuracy and dimensional matching of the rolling surface of the entire bearing roller batch, and further. , The straight groove of the first grinding disk and the spiral groove of the second grinding disk have tens and hundreds of joints, that is, tens and hundreds of bearing rollers to be processed. It is ground at the same time, and thus the processing efficiency of the rolling surface of the bearing roller is improved and the processing cost is reduced.

And since the base surface of the first grinding disk is designed to be a conical surface, a longer straight groove is installed on the front surface of the first grinding disk, especially when the entrance of the straight groove is installed on the outer edge of the first grinding disk. That is, more bearing rollers to be machined will be ground at the same time.

Further, by designing the spiral groove work surface of the second grinding disk, the linear feed motion of the bearing roller to be machined along the linear groove baseline of the first grinding disk can be carried out through the spiral feed of the spiral groove work surface, and the roller carrying means. The requirement for axial feed capacity is reduced.

Since the magnetic structure is installed inside the second grinding disc, the magnetic attraction force of the spiral groove work surface of the second grinding disc with respect to the workpiece bearing roller of the ferromagnetic material is applied to the workpiece bearing roller of the ferromagnetic material. Introduced into the force equilibrium system, the magnetic attraction force is independent of the working pressure applied to the bearing roller to be processed of the ferromagnetic material due to the relative proximity of the first grinding disk and the second grinding disk during grinding. As a result, "the slip friction drive torque of the spiral groove work surface of the second grinding disk with respect to the rotation of the machined bearing roller of the ferromagnetic material around the axis itself is determined by the machined bearing roller of the ferromagnetic material. It is larger than the slip friction resistance torque of the linear groove work surface of the first grinding disk with respect to the rotation around its own axis. "
It becomes easier to realize the condition.

Step 1, In the second grinding disk 22, the transient surface 2112 connecting the adjacent straight grooves on the front surface 211 of the first grinding disk and the transient surface 2212 connecting the adjacent spiral grooves on the front surface 221 of the second grinding disk are as close as possible. However, the rolling surface 32 of the cylindrical roller to be machined in the grinding area comes into surface contact with the linear groove working surface 21111 of the first grinding disk and in line contact with the first working surface 221111 of the second grinding disk spiral groove. No, that is, the first
Until the space of each grinding area surrounded by the straight groove working surface 21111 of the grinding disk and the spiral groove working surface 22111 of the second grinding disk can accommodate only one cylindrical roller 3 to be machined, on the axis thereof. It approaches the first grinding disk 21 along the line.

Step 2, corresponding to the first rotation method of the grinding disc set 2, the first grinding disc 21 is rotationally driven around the axis thereof with respect to the second grinding disc 22 at a low speed, and the grinding disc set 2 is driven.
The second grinding disk 22 corresponds to the second rotation method of the above, and the first grinding disk 21 is around its axis.
