Figure 8 is a longitudinal cross-sectional view showing the feeding operation of the compensation error type bearing screw wheel according to the first example of the present invention. Fig. 9 is a partial cross-sectional view showing the relationship between the compensation cap, the fixing device, the warp bearing, and the screw in the case where the screw of the first example of the present invention has a triangular cross section. 8 201009219 Referring to FIGS. 3 to 5, a compensating error type bearing screw conveying device according to the present invention may include a screw shaft (200) which forms a screw (2 1 〇) on an outer circumferential surface, and the above-mentioned screw shaft (200) is inserted inside Cylindrical nut body (300). The screw shaft (200) is connected to a rotary power such as a motor, and the nut body (300) is connected to the starter. The screw shaft (2〇〇) can be fixed as needed, and the nut body (300) can be connected to the rotary power and the starting member. In particular, when the length of the screw shaft (2〇〇) is somewhat long, the nut body (300) is not linearly moved by the external power rotating screw shaft (2〇〇), but the nut body (3〇〇) is rotated by external power. The Straight® line moves more efficiently on the fixed screw shaft (200). In the example of the present invention, an example in which the nut body (300) is linearly moved by externally rotating the screw shaft (2 turns) is described, but the present invention is not limited to these. The above description is intended to be applied to an example in which the nut body is rotated by external force to rotate the nut body while linearly moving on the fixed screw shaft (200). One of the features of the compensating error type bearing screw conveying device according to the present invention is a screw (201) thread path and an engaging path formed along a screw shaft (200) on the outer circumferential surface of the nut to form a plurality of mounting holes (3丨〇 And a radial bearing (500) that rotates by connecting the rotating shaft (600) to the mounting hole (3 1 〇). As shown in Fig. 4, at this time, the radial bearing (500) has its outer wheel surface adjacent to the threaded or threaded side of the screw (201). Thereby, a nut internal thread that meshes with the external thread of the above-described screw shaft (200) is formed. At this time, in order to rotate in the bidirectional direction of the screw shaft (200), the nut body (3 turns) can be moved in both directions, and half of the plurality of radial bearings (5 turns) are screw shafts (2 turns). Adjacent to the screw (2〇1) when rotated in the clockwise direction, the remaining half is the abutment screw (2〇1) when the screw shaft (200) rotates only in the counterclockwise direction. Thus, the screw 201009219 shaft (200) rotates in any direction and the nut body (300) moves in any direction. The radial sleeve (500) is not displaced at a regular position, adjacent to the screw (201). Water chest or side, and only rotate. According to the screw conveying device of the present invention, according to such a simple structure, not only the friction between the screw shaft (200) and the nut body (3 〇〇) but also the internal parts of the conveying device for linear movement are completely cut off. Conflict, while minimizing vibration, noise and damage to radial bearings. According to the compensation error type bearing screw conveying device of the present invention, the other special feature is that when the radial bearing (500) is connected to the rotating shaft (600) and is disposed in the mounting hole (310) of the nut body (300), Adjust the position of the center of the radial shaft (500) screw shaft (200). To this end, the compensating error type bearing screw conveying device according to the present invention is provided with a position adjuster of the radial bearing (500). The position adjuster is such that the machining precision of the screw (201), the nut body (3〇〇), the mounting hole (31〇), the rotating shaft (600), and the radial bearing (500) is lowered, and compensation is also required after assembly. The above radial bearing (5 〇〇) failed to properly pre-stress the adjacent screw (201) or due to the conflict and friction between the parts of the screw conveyor. © A ^ JZ. Raw raft, vibration, heat generation, When the backlash is equal, the gap between the radial bearing (5〇〇) and the screw (201) and the preload are adjusted and corrected. Referring to Figures 3, 6 and 7, a position adjuster according to a first example of the present invention includes a support frame (3 60) formed at a lower end of a nut body (31 安装) mounting hole (31) inserted in the above-mentioned mounting hole (31〇) a spring (700) provided on an upper portion of the support frame (31〇), inserted in the mounting hole (3 10) and provided on an upper portion of the spring (7〇〇) to fix a radial bearing below ( 500) The fixing shaft (400) of the rotating shaft and the 201009219 part of the above-mentioned fixing device (4〇〇) inserted into the mounting hole (31〇) are screwed together, and the above fixing device (4〇〇) is pressed The magazine (10) is pressed in the direction, and the compensation cap (8〇〇) of the height of the screw shaft in the center of the fixing device is adjusted according to the degree of screw tightening. The holder (400) can be moved up and down within the mounting hole (31〇). In order to make the mounting hole (3 10) cylindrical, the above-mentioned holder (side) is formed in a cylindrical shape which is inserted into the mounting hole (310) and movable. Further, the lower body diameter of the body (410) of the above-mentioned holder is smaller than the upper outer diameter, and it is preferable to form a step difference between the upper and lower sides. Insert the above spring © (700) in the lower part of the body (410) of the small outer diameter holder, and the step is stopped. A shaft hole (420) for fixing a rotating shaft (600) of a radial bearing (5 〇〇) is formed at a lower portion of the above-mentioned holder (400). The shaft hole (42〇) is provided with a tapping, and is inserted into a portion of the shaft hole (42〇) of the rotating shaft (600) to form a screw that is combined with the screw tapping, and the rotating shaft (600) is screwed to the shaft. The hole (42 〇) is preferred. The lower portion of the holder (400) described above forms a bearing pad (430) that is obliquely recessed into a portion of the radial bearing (500). A portion of the radial bearing (500) is inserted into the bearing pad (430). The remaining portion of the outer wheel abutting screw (210) is better than the ®. At this time, the inclination angle of the bearing pad (430) differs depending on the structure of the screw (2 10) of the screw shaft (2 ') 'but in any case, the outer wheel of the radial bearing is also for abutting the snail; f dry (2 1 0) threaded horn or The side 'forms a certain angle of inclination. Further, at this time, the shaft hole (420) is formed on the floor surface of the bearing pad (430), and the direction thereof is perpendicular to the floor surface. Thus, the mounting hole (3 1〇) is perpendicular to the length of the screw shaft (2〇〇) and the radial bearing (500) can be kept inclined. The mounting angle of the radial bearing (500) can also be changed by only replacing the holder (4〇〇). As shown in FIG. 3 and FIG. 6, the protrusion (440) is integrally formed at the lower portion of the machine 11 201009219 of the holder (400), and the protrusion is formed on the support frame (360) at the lower end of the mounting hole (310). The brake groove (320) of (44〇) is inserted into the radial bearing (5〇〇) of the holder (400) and fixed in a certain direction. The lower end of the spring (700) is adjacent to the upper surface of the support frame (36〇), and the upper end is sandwiched by the lower portion of the body (410) of the holder. As shown in Fig. 7, the above-mentioned compensating cap (8 〇〇) has an external thread formed on the outer surface thereof, and an internal thread which is coupled to the external thread of the above-mentioned compensating cap (8〇0) is also formed on the inner surface of the upper portion of the mounting hole (3 10). © According to the position adjuster of the first example of the present invention having the above structure, as shown in Fig. 7, the user generates a screw (2〇1) and a radial bearing (5) due to machining errors of parts or wear of parts during use.隔离) When the isolation phenomenon and compression force are too large or the preload is not appropriate, move the compensation cap (800) down or above. Then, the fixing device (400) overcomes the rebound force of the spring (700) or the support of the rebound force in the lower portion of the compensation cap (800), and moves down or on the side. Therefore, it is easy to disassemble the entire screw conveying device. Adjust the gap and preload between the screw (201) and the radial bearing (500). ® Figure 8 is a compensation error type screw conveyor (1〇〇a) for adjusting the clearance between the screw (201) and the radial bearing (5〇〇) according to the compensation cap (800) and according to the screw shaft (200) Rotate the nut body (300) to the left and right. The radial suction (500) converts the rotational motion of the screw shaft (2 turns) without loss and precisely converts it into a linear motion of the nut. The cross-sectional shape of the screw of the compensation error type screw conveying device screw shaft (200) according to the first example of the present invention is as shown in FIGS. 3 to 8, and is applicable not only to the semicircular groove but also as shown in FIG. Other shapes such as triangles, ladders, etc. 12 201009219 are also directly applicable. As shown in Fig. 9, when the cross-sectional shape of the screw is triangular, the radial bearing (500) preferably abuts the side of the screw thread. At this time, the high-speed rotating screw shaft (200) also has a good abutment between the screw (201) and the radial bearing (5〇〇), and the noise is increased, and the supporting force in the axial direction is increased, thereby safely conveying the nut body (300). .

The spring is inserted into the mounting hole (3iQ) and is disposed on the upper portion of the above-mentioned elastic crystal 13 201009219 (700) and can be inserted into the rod pin. a screw groove (450) is formed on the upper portion, and a holder (400) for fixing a rotating shaft (600) of the radial bearing (500) is inserted below the screw shaft (200) in a longitudinal direction thereof through the upper portion of the mounting hole (3 10) a pin hole (350), and a screw groove (450) inserted into the pin hole (3 50) and the holder (400), and a screw for adjusting the fixing device (400) according to a diameter inserted in the screw groove (450) portion A compensation pin (900) of the height of the shaft (200) in the center direction. The compensation pin (900) is first inserted into the mounting hole (3 10) in conjunction with the spring (700) and the retainer (400) of the radial bearing (500), and is inserted into the nut body from the side of the nut body (300). The pin hole (350) of (300) and the screw groove (450) above the holder. As shown in FIGS. 10 to 12, when the position compensation amounts of the respective radial bearings (500) are the same, a plurality of mounting holes provided in the longitudinal direction of the screw shaft (200) are pressed by a compensation pin (900) having a sufficiently long length. The holder (400) on (310). However, as shown in Fig. 17, the compensation pin (900a) is slightly smaller than the screw groove (450) of the holder (400) because the machining error or the degree of wear differs from each other, and the position compensation amount of the radial bearing (500) is different. The length is different so that each holder (400) is separately mounted and the compensation pin between the compensation pins (900a) can be inserted into the compensation pin. Referring to Figures 10 and 13, a position adjuster according to a second example of the present invention uses a compensation pin (900) instead of a compensation cap (800) as a compensation error tool, unlike the position adjuster according to the first example of the present invention. A screw groove (450) is formed on the holder (400), and a pin hole (350) is formed in the nut body (300). Although not shown, the overall length of the compensation pin (900) or the compensation pin (900a) and the auxiliary pin is shorter than the length of the nut body (300), so that the pin hole (350) is not filled with both side ends, and it is not filled. The part is combined with the screw and the compensation pin 14 is fixed. 201009219 (900) The position adjuster according to the second example of the present invention adjusts the compensation amount by the diameter of the compensation pin (9〇〇), and the compensation error is fine. Referring to Fig. 14 and Fig. 5, when the diameter of the compensation pin (900) is increased, the holder (4) and the rotatable radial bearing (500) are lowered. When the diameter of the compensation pin (900) is reduced, the above-mentioned holder (400) and the radial bearing (5 〇〇) rise according to the spring force of the spring (7 〇〇). At this time, the support frame (360) and the spring (700) continue to provide an upward elastic support force to the holder (4〇〇). Eight-body said 'As shown in Figure 15, the holder (4〇〇) is clamped into the pin hole (350) of the nut body (3〇〇) and the screw groove (45〇) of the holder (4〇〇) , holder 〇〇〇) bounces to the upper part according to the spring (700) being elasticized. The compensation pin (9 〇〇) sandwiched in the screw groove (45 〇) of the above-mentioned holder (400) is also pressurized in the upward direction, and a part of the compensation pin (900) is inserted into the pin hole (35 〇) to be caught. Therefore, when the diameter of the compensation pin (900) is large, the small diameter compensation pin (9〇〇) is inserted, and the fixing device (400) is pressed downward according to the difference in diameter, and the radial bearing is directed to the screw shaft (2〇〇) ) The center direction shifts. By these compensations, the amount of wear due to machining errors and friction causes the screw (200) and the radial bearing (5 〇〇) to abut each other with an appropriate pressure. Therefore, the radial bearing (500) described above has less noise than the ball screw during the abutment of the screw, and a precise conveying distance is obtained. Further, when the preload is lowered due to wear of the radial bearing (5 〇〇), etc., the "uncompromised integral screw conveying device also compensates for the error quickly", and Fig. 16 is the adjustment of the screw (2〇1) and the diameter according to the compensation pin (900). A compensation error type screw conveying device (i〇〇a) for the gap between the bearings (5〇〇) and the preloading pressure 15 201009219 A diagram of the nut body (3〇〇) is conveyed left and right by the rotation of the screw shaft (200). The radial bearing (500) described above rotates the rotational motion of the screw shaft (200) without loss and precisely converts it into a linear motion of the nut. Further, when the radial bearing (5 〇〇) abuts the screw (200) and wears for a long time and wears, the radial bearing (500) adjacent to the screw (2 预) is preloaded and lowered to cause a gap. This causes conflicts between the abutments and noise, vibration, heat generation, and backlash. At this time, the compensation pin (900) of the larger diameter is clamped into the pin hole (35〇) of the nut body (300), and the front small diameter compensation pin (9〇〇) is separated from the nut body (3〇〇). Screw hole (450) for pin hole (35〇) and ^ holder (400). When the pin hole (35〇) of the nut body (300) and the screw groove (450) of the holder (400) are inserted into the larger diameter compensation pin (900), the compensation pin (9〇〇) is increased in diameter. Large and large pressure holder (4〇〇) 'This eliminates conflicts between parts and noise, vibration, heat generation, backlash and other issues. The screw cross-sectional shape of the screw shaft (200) of the compensation error type screw conveying device according to the second example of the present invention is as shown in Figs. 1A to 1D, and is applicable not only to the groove of the semicircular shape but also as shown in Fig. 18a and As shown in Fig. 18b, other shapes such as a triangle and a ladder are also directly applicable. The screw surface is in the shape of a ladder. As shown in Fig. 18a, the radial bearing (5〇〇) preferably abuts the side of the screw thread. At this time, the 'high-speed rotating screw shaft (200) also has a good abutment between the screw (2〇1) and the radial bearing (5〇〇), and the noise is small, and the supporting force in the axial direction is increased, thereby safely conveying the nut body ( 300). However, when the screw shaft (2 turns) is not rotated at a high speed, as shown in Fig. 18a, the radial bearing may abut the screw (2 turns) threaded angle. According to the compensation error type screw conveying device of the present invention, as shown in Fig. 12, 201009219, a communication mounting hole (310) is formed on the nut body (300) and supplied to the friction portions of the radial bearing (500) and the screw (200). Lubricating oil supply hole for oil (3 70). Further, as shown in Figs. 19 and 20, in order to communicate the lubricating oil supply hole (360), a lubricating oil storage tank (1000) is provided outside or inside the nut body (300). When a lubricating oil storage tank (1〇〇〇) is provided inside the nut body (3〇〇), as shown in Fig. 20, a mounting hole (31〇) at both ends of the nut body (300) is inserted into the radial bearing (500). ), a lubricant storage box (1000) is installed in the middle mounting hole. These are used to improve the friction of the screw (21〇) and the strange bearing (5〇〇), and reduce wear. INDUSTRIAL APPLICABILITY According to the present invention having the above structure, the structure is simple and the friction m-line transportation between the screw shaft and the nut is minimized, the collision between the parts in the conveying device is completely cut off, and vibration, noise, and Because of the reduced precision of the part processing, there is a gap between the parts. 2 The time is used to compensate for the wear according to the friction between the radial bearing and the screw. This eliminates the noise caused by the conflict between the parts, and the vibration '& It has an epoch-making effect of increasing the life of the screw conveying device. The rotational motion is lossless and precise for energy efficiency and delivery. Further, according to the present invention, the ground of the screw shaft is converted into a linear motion of the nut. Therefore, a high precision bearing screw transfer device.
