Embodiments of the Invention

Hereinafter, embodiments of the present invention will be explained with reference to the figures.

[First Embodiment]

The first embodiment is a bearing 10 that is a first component 1A and a second component 1B rotatably holding. 1 is a cross-section that in a device 1 arranged bearings 10 represents (cross section through a surface comprising the axis of rotation AX1). Is it the device 1 around a reduction gear, is the first component 1A z. B. a component (housing), which rotates by the driving force, which is transmitted by a built-in in the reduction gear vibration gear, with a lower rotational speed than the rotational speed of a servomotor. Further, the second component 1B a vibrationally holding the vibration gear member (rotation axis) or a vibration gear in the space to this component (rotation axis) holding member (retaining flange). As examples of the device 1 Apart from a reduction gear, a machine tool, a rolling machine, an airplane, a motor vehicle or a railroad can be cited.

As in 1 pictured is a shaft bearing 1 a rolling bearing that has a plurality of rollers 110 a cage 120 , an outer ring (outside track) 130 and an inner ring (inner track) 140 having.

The outer ring 130 and the inner ring 140 are annular components which are concentrically arranged about a rotation axis AX1 and have a different diameter. The outer ring 130 and the inner ring 140 are each at a first component 1A and a second component 1B the device 1 z. B. attached by insertion.

The outer ring 130 and the inner ring 140 each have a rolling surface inclined to the axis of rotation AX1 132 and rolling surface 142 on. Between the rolling surface 132 of the outer ring 130 and the rolling surface 142 of the inner ring 140 is the cage 120 arranged.

2 is a perspective view of the cage 120 alone. As in 2 shown, it is at the cage 120 around a basket-shaped cage having a plurality of pockets P and formed annularly.

The cage 120 has a first annular part 122 and a second annular part 124 and a plurality of pillars 126 on. The first annular part 122 is one on the side of the one end of the cage 120 in the axial direction of the bearing 10 formed annular part. The second annular part 124 is one on the side of the other end of the cage 120 in the axial direction of the bearing 10 formed annular part. The second annular part 124 is concentric with the first annular part 122 arranged and has a smaller diameter than the first annular part.

The majority of piers 126 is between the first annular part 122 and the second annular part 124 arranged in the circumferential direction about the rotation axis AX1 as a center at a certain distance next to each other. The respective pillars 126 run between the first annular part 122 and the second annular part 124 and connect the first annular part 122 and the second annular part 124 together. This is the cage 120 formed overall in a truncated cone shape.

The pockets P have one of the first annular part 122 , the second annular part 124 and two adjacent pillars surrounded rectangular shape. The respective pockets P hold the rollers 110 , At the warehouse 1 According to the present embodiment, the rollers 110 inside the respective pockets P holding cage 120 on the outer ring 130 mounted, and then the inner ring 140 mounted so that between it and the outer ring 130 the roles 110 and the cage 120 lie. The roles 110 are taken from below the pockets P in the pockets P. The width of the pockets P (distance between two adjacent pillars 126 ) is slightly narrower than the diameter of the rollers 110 , So the roles 110 not before mounting on the outer ring 130 fall out of the pockets P, they are z. B. in the pockets P (between two adjacent pillars 126 ).

While the roles 110 each between the outer ring 130 and the inner ring 140 on the respective rolling surface 132 and rolling surface 142 Roll, they rotate about an axis of rotation AX1 inclined to the axis of rotation AX1. This will cause the outer ring to rotate 130 (and the first component 1A) and the inner ring 140 (and the second component 1B) about the roles 110 relative to the axis of rotation AX1.

In addition, in the pockets P through a restriction plate 122A of the first annular part 122 and a second restriction plate 124A of the second annular part 124 a shift of roles 110 limited in the direction of the axis of rotation AX2. Further, in the pockets P through a side surface 126A two adjacent pillars 126 , through the rolling surface 132A and the rolling surface 142A a shift of roles 110 limited in the direction orthogonal to the rotation axis AX2 direction. In other words, the first annular part act 122 , the second annular part 124 and the pillars 126 as restriction parts, which is a shift of roles 110 in the direction of the rotation axis AX2 and in the direction orthogonal to the rotation axis AX2 direction.

3 is a longitudinal section showing the condition during assembly of the bearing 10 according to the present first embodiment shows. In 3 is the outer ring 130 at the first component 1A attached and the rolling surface 132 is arranged in an upwardly facing position. On the rolling surface 132 are the majority of roles 110 and the roles 110 in the respective pockets P holding cage 120 arranged.

The outer ring 130 has a reference surface 134 on that to the rolling surface 132 forms an angle. The reference surface 134 is an area that coincides with one end of the rolling surface 132 is connected and if the rolling surface 132 has an upward facing position, also pointing upwards. In other words, the reference surface shows 134 if the rolling surface 132 has a down facing position, also down. In the present first embodiment, the reference surface is 134 However, in another embodiment, it may also be a surface that forms another angle to the axis of rotation AX1 than orthogonal.

On the outer circumference of the annular part 122 a guide part G is formed over the entire circumference. On the guide part G is on one of the reference surface 134 of the outer ring 130 opposite position formed a guide surface GS.

The cage 120 is on the outer ring 130 arranged such that the guide surface GS on the reference surface 134 of the outer ring 130 is present (has more precise surface contact). Characterized in that the guide part G (the guide surface GS) at a certain position (reference surface 134 ) of the outer ring 130 is applied, the position of the cage 120 to the outer ring 130 and the location of the cage 120 established.

Specifically, both the guide surface GS of the guide member G and the reference surface 134 of the outer ring 130 an annular shape. Further, the radial width of the guide surface GS and the reference surface 134 about the same. Because of the cage 120 such on the outer ring 130 is arranged that the entire guide surface GS on the entire reference surface 134 Surface contact has, is the position of the cage 120 opposite the outer ring 130 determined at the planned appropriate position.

Further, even in the event of attempting the cage 120 in a situation in which z. B. the guide surface GS to the reference surface 134 is inclined to the outer ring 130 to mount, by the surface contact of the guide surface GS with the reference surface 134 corrected this inclination, and the position of the cage 120 to the outer ring 130 determined at the planned appropriate position.

Because the position and location of the cage 120 to the outer ring 130 is determined to the appropriate position and position, and the position and position of the portion which forms the pockets P (first annular part 122 second annular part 124 and two adjacent pillars 126 ) to the rolling surface 132 of the outer ring 130 set appropriately. Because the roles 110 in the appropriate position and position to the rolling surface 132 arranged to be pressed and held in the pockets P, also becomes the position and location of the rollers 110 on the rolling surface 132 appropriate.

At the time when the guide surface GS at the reference surface 134 is present, there are pressed into the pockets P roles 110 in a slightly floating state to the rolling surface 132 of the outer ring 130 , As in 3 shown, are pushed into the pockets P roles 110 if the inner ring 140 from above the outer ring 130 is mounted, through the rolling surface 142 of the inner ring 140 pressed down and come with the rolling surface 132 in contact, getting into a state in which they are between the rolling surface 132 and the rolling surface 142 be held under a uniform load (preload) in the pockets P.

Accordingly, in the first embodiment, the guide surface GS becomes at the reference surface 134 rests on the position and location of the cage 120 and the respective roles 110 to the outer ring 130 set appropriately. Therefore, the disadvantage is avoided that z. B. other sections than the rolling surface 142 of the inner ring 140 on the peripheral surface of the rollers 110 meet and dents on the peripheral surface of the rollers 110 form. As a result, a worker can use the inner ring 140 easy to assemble.

Second Embodiment

The second embodiment will be described with reference to FIG 4 to 6 explained. The present second embodiment relates to a device 1' having a structure according to that of a first component 1A over two camps 10a . 10b each second components 1B and 1B ' are attached. 4 (a) shows a cross section of the device 1' (Cross section through a surface comprising the rotation axis AX1). The device 1' is z. B. a reduction gear. Is it the device 1' around a reduction gear, is the first component 1A z. B. a housing of the reduction gear, and the second component 1B and the second component 1B ' are each z. B. a rotation axis of the reduction gear or a retaining flange of the reduction gear. As examples of the device 1 Apart from a reduction gear, a machine tool, a rolling machine, an airplane, a motor vehicle or a railroad can be cited.

As in 4 (a) shown, become the first component 1A and the second component 1B about a camp 10a rotatably held to each other and further, the first component 1A and the second component 1B ' over the camp 10b rotatably held each other. The warehouse 10a and the camp 10b each have the same structure as the bearing 10 of the first embodiment. Hereinafter, the same reference numerals are used to simplify the explanation for the same structural elements. Specifically, the structure elements of the warehouse 10a a a at the back of the number of the structural element of the camp 10 attached and attached to the structural elements of the warehouse 10b is a b at the back to the number of the structural element of the camp 10 attached. As in 4 (a) is shown in the warehouse 10a the cage 120a in one with the side of the first annular part 122a arranged downward state. Further, in the warehouse 10b the cage 120b in one with the side of the first annular part 122b arranged upward state.

In 4 (b) is an enlarged view of the portion of the bottom of the first component 1A (Section that the camp 10a and the sealing component 2 includes). As in 4 (b) is shown in the section of the bottom of the device 1' the warehouse 10a arranged, and over the camp 10a become the first component 1A and the second component 1B rotatably held each other. At the bottom of the first component 1A will be between the inside of the first component 1A and the outside of the second component 1B the sealing component 2 fastened by the interior of the device 1' enters a sealed to the outside state.

5 (a) to 5 (e) are illustrations showing the assembly of the device 1' explain. First, as in 5 (a) shown, two outer rings 130a and 130b at the first component 1A (eg the housing of a reduction gear) fastened by pressing.

Next, as in 5 (b) shown the roles 110a holding cage 120a in one with the side of the second annular part 124a upward state from below to the outer ring 130a approximated. The roles 110a are taken from above the pockets Pa in the pockets Pa. The width of the pockets Pa (distance between two adjacent pillars 126a) is slightly narrower than the diameter of the rollers 110a , Therefore, the rollers accommodated in the pockets Pa become 110a from two adjacent piers 126a supported, so they do not escape from the pockets Pa and out of the cage 120 fall out.

As in 5 (c) is shown, the sealing component 2 at the first component 1A attached. Specifically, it is the sealing component 2 around an elastically deformable annular component having a slightly larger outer diameter than the inner diameter part 1Aa of the first component 1A having. The sealing component 2 is caused by elastic deformation in the inner diameter part 1Aa of the bottom part of the first component 1A used.

At the guide part Ga of the cage 120a On the opposite side of the guide surface GSa, a seating surface 122aB is formed over the entire circumference or a part of the first annular part 122a formed in the circumferential direction. The cage 120a becomes with the seating surface 122aB as a bottom surface on an inner wall surface 2A the one at the first component 1A attached sealing component 2 placed in a position in which the guide surface GSa of the reference surface 134a of the outer ring 130a opposite. Because of the cage 120a on the inner wall surface 2A is put on, the cage becomes 120a about the sealing component 2 at the first component 1A provisionally held. Therefore, it also happens in the event that holding the cage 120a by a holding means (the hand of a worker, a tool, etc.) is released, not to a fall of the cage 120a from the first component 1A ,

Based on 6 Now the structure of the inner ring 140a explained, the z. B. by pressing into the second component 1B (For example, the rotation axis of a reduction gear) is attached. On the inner ring 140a is one to the rolling surface 142a in the radially outer direction above and also in the inner periphery of the sealing component 2 matching flange 144a educated. The flange 144a is over the entire circumference or part of the inner ring 140a formed in the circumferential direction and has an orthogonal to the radial direction of the inner ring 140a running claw 146a (see enlarged view of 6 ).

As in Figure 5 (d) and 5 (e) shown, becomes the second component 1B at the first component 1A assembled. Specifically, the second component 1B on the side of the first component 1A (along the axis of rotation AX1 upwards) raised so that the flange 144a of the inner ring 140a the inner diameter part of the sealing component 2 happens. The cage 120a is in a state where part of the roles 110a in the radial inner direction to the inner diameter part of the sealing component 2 is disposed on the sealing component 2 placed. Passed the flange 144a the inner diameter part of the sealing component 2 , the claw remains 146a at the end surface of the rollers 110a hang. Will be in the condition of at the end face of the rollers 110 hinged claw 146a the second component 1B on the side of the first component 1A raised, comes the claw 146a after the role 110a from the pillar 126a of the cage 120a something was pushed up, with the pillar 126a in contact and pushes the cage 120a and the roles 110a on the side of the first component 1A high.

The roles 110a and the cage 120a be through the inner ring 140a (mainly by the claw 146a) without changing the situation on the side of the first component 1A raised. Therefore, a guide surface GSa passes while maintaining the reference surface 134a opposite state with the reference surface 134a in surface contact (abutment). In other words, the flange 144a (the claw 146 ) the function on the sealing component 2 mounted cage 120a on the side of the reference surface 134a to move and the guide part GSa with the reference surface 134a to bring into contact.

As in 5 (e) is represented by the fact that the guide surface GS on the reference surface 134 rests on the position and location of the cage 120 and the roles 110 to the outer ring 130a set to the appropriate position and location. As in 5 (e) shown seals the sealing component 2 the gap (gap of a ring shape) between the first component 1A and the second component 1B , Thereby, that by the sealing component 2 the space between the first component 1A and the second component 1B Sealed will leak from around the camp 10a and 10b filled lubricating oil prevented.

In the present second embodiment, at the stage of assembling the second component 1B at the first component 1A the position and location of the cage 120a and the roles 110a automatically set to the appropriate position and location. Therefore, the disadvantage is avoided that z. B. other sections than the rolling surface 142a of the inner ring 140a on the peripheral surface of the rollers 110a meet and dents on the peripheral surface of the rollers 110a form. As a result, a worker can use the inner ring 140a easy to assemble.

As in 5 (e) shown, the cage 120b on the outer ring 130b placed so that the guide surface GSb with the reference surface 134b of the outer ring 130b Contact has (rests). If the guide surface GS is at the reference surface 134b On, as well as the first embodiment, the position and the position of the cage 120b and the roles 110b to the outer ring 130b set appropriately.

Then, as in 5 (e) shown, the inner ring 140b by z. B. Press-fitting to the second component 1B ' (eg retaining flange) attached.

Next, in the same sequence as in the case of 3 explained assembly of the inner ring 140b to the outer ring 130b assembled. Because the position and location of the cage 120b and the roles 110b to the outer ring 130 is determined appropriately, the disadvantage is avoided that z. B. other sections than the rolling surface 142b of the inner ring 140b on the peripheral surface of the rollers 110b meet and dents on the peripheral surface of the rollers 110b form. A worker can thus use the inner ring 140b easy to assemble.

In the above, an embodiment illustrating the present invention has been explained. However, the embodiment of the present invention is not limited to the above, but various modifications are possible within the technical scope of the present invention.

On the other hand, in another embodiment, the guide member G can be applied without limitation to the entire circumference of the annular member 122 even be formed on only one part. As an example, the guide member G has an angular dimension of about 20 °, and also in the circumferential direction of the first annular member 122 can be formed at a distance of 180 ° in two places or at a distance of 120 ° in three places. In other words, by using a structure in which at at least two locations, the guide surface GS on the reference surface 134 rests on the position and location of the cage 120 to the outer ring 130 be determined appropriately.

In the above embodiment, the outer ring rotate 130 and the inner ring 140 relative, when the guide surface GS with the reference surface 134 Contact has. In contrast, it can also be provided in another embodiment that the outer ring 130 and the inner ring 140 rotate relatively when the guide surface GS with the reference surface 134 has no contact. Specifically, when assembling the inner ring 140 on the outer ring 130 a greater preload than the above embodiment is exerted. This will make the cage 120 elastically deformed such that the guide surface GS of the reference surface 134 by a certain size, if z. B. a part of the inner ring 14 with the cage 120 comes into contact. In this case, turn the outer ring 130 and the inner ring 140 relative, when the guide surface GS on the reference surface 134 in a contactless state. This can cause abrasion of the guide surface GS and the reference surface 134 be avoided.

Likewise, in the above embodiment, the inner ring 140 of the camp 10 and the second component 1B the device 1 a separate structure, wherein in another embodiment, the inner ring 140 and the second component 1B can also be formed in one piece.

Further, in the above embodiment, the guide part G is attached to the first annular part 122 of the cage 120 However, in another embodiment, the guide member G (and the guide surface GS) but also on the second annular part 124 be formed. In this case, at the guide surface GS of the second annular part 124 opposite position, the reference surface of the outer ring 130 (or the inner ring 140 ) educated.

Furthermore, it is the roles 110 the above embodiment to cylindrical rollers, which can be replaced in another embodiment, however, by tapered rollers.

Further, in the above embodiment, the assembly is made on the inner ring 140 in a state in which the appropriate position and location of the cage 120 and the roles 110 to the outer ring 130 However, in another embodiment, a structure may be applied, in which the mounting on the outer ring in a state in which the appropriate position and position of the cage and the rollers is fixed to the inner ring. This structure is based on 7 explained.

7 is the same view as in 3 , which is a view for explaining the mounting of a bearing 10 " is. As in 7 shown, has an inner ring 140 ' a reference surface 144 ' with the same function as the reference surface 134 on, and a cage 120 ' points to one of the reference surface 144 ' opposite a guide surface GS " on.

Bearing, which has an outer ring, an inner ring arranged concentrically with the outer ring, a plurality of rollers arranged between the outer ring and the inner ring, and a cage holding the plurality of rollers, the cage having a guide part which abuts either the inner ring or the outer ring during assembly, whereby the position of the cage to which a ring is set. Warehouse after Claim 1 wherein the cage has a restriction member restricting a displacement of the rolling elements in the direction of the rotation axis and the direction orthogonal to the rotation axis, and in that the guide member rests on one of the rings during assembly, the position of the restriction member to the rolling surface of the one Rings is set. Warehouse after Claim 1 or Claim 2 wherein the cage has a pair of concentrically arranged annular bodies respectively connected by a plurality of pillars arranged side by side in the circumferential direction of the annular bodies at a certain distance, and the guide member is formed on one of the annular components of the pair in that it projects over the entire circumference of the annular body or a part thereof in the radial outer direction of the annular body. Stock after one of Claims 1 to 3 , wherein the fact that the guide member rests during assembly on one of the rings, the position of the restriction member is set to the rolling surface of the ring in question. Stock after one of Claims 1 to 4 wherein the one ring has a reference surface which is also directed upward in an upward position of the rolling surface of the one ring, and in which the cage is fixed to the one ring by the abutment of the guide member on the reference surface. Stock after one of Claims 1 to 4 wherein the one ring has a reference surface which is also directed downwards in a downward position of the rolling surface of the one ring, and in which the cage is fixed to the one ring by the abutment of the guide member on the reference surface. Stock after one of Claims 1 to 6 wherein the guide member has a guide surface by which the position of the cage is fixed to the relevant ring during assembly by the surface contact with the reference surface. Device having a bearing according to Claim 6 or the up Claim 6 referred back Claim 7 comprising a first component to which the one ring is mounted, a second component to which the other ring of the inner ring and the outer ring is mounted, and a sealing component, which is arranged at a position opposite to the reference surface and the gap sealed between the first component and the second component. Device after Claim 8 further comprising a component whereby, during assembly of the patch on the sealing component, the cage is moved to the side of the reference surface and the guide member abuts the reference surface. Device after Claim 9 wherein the cage is mounted on the sealing component when mounted in a position where the guide portion of the reference surface is opposed, the sealing component is an annular component sealing the annular space between the first component and the second component, the means for abutment is formed on the other ring, protrudes in the radial outer direction to the rolling surface of the other ring and also has an outer circumference, which fits in the inner periphery of the sealing component, when mounting the second component on the first component passes through the inner diameter of the sealing component, with the Sealing component patched cage and the rolling elements comes into contact, without changing the position of the cage and the rolling elements moves to the side of the reference surface and brings the guide member with the reference surface in contact.
