[0002] With the development of wind power gear box technology, most of the bearings of the products are designed as bearings without outer rings. For the assembly mode of two bearings of a planetary gear as shown in the figure, the lower bearing is first placed vertically on a special platform, the planetary gear is assembled into the bearing from top to bottom, the upper bearing is hoisted and vertically assembled into the planetary gear, and the bearing is fixed by a tool, and then the planetary gear device can be hoisted by a special lifting tool. Figure 1 The bearing rollers are fixed by rubber bands in a circle, and after most of the bearing rollers are assembled into the inner hole, the rubber bands need to be cut off.

[0003] In this assembly mode, the planetary gear or the bearing may not be hoisted flat, which may cause the problem of jamming during assembly, especially when the lower bearing is assembled, it is not convenient to check, and the planetary gear is heavy, and when jamming occurs, the bearing may be damaged by impact, and in addition, when the lower bearing is assembled, there is a safety hazard in the process of cutting the rubber band.

[0004] Therefore, how to solve the problem of impact damage to the bearing during the assembly of the planetary gear is a problem that needs to be solved by the technical personnel in the field. SUMMARY

[0005] Therefore, the purpose of the present application is to provide a bearing clamp which can realize the installation of the bearing in the horizontal direction to avoid impact damage to the bearing during the assembly of the planetary gear.

[0006] In order to achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] The core of this invention is to provide a bearing clamp, in which the connecting rod assembly 3 moves axially along the support rod 1, thereby driving the chuck assembly 4 to extend and retract radially in the support rod 1, so as to realize the contact and separation of the chuck assembly with the bearing inner hole, thereby realizing the horizontal installation of the bearing, so as to avoid the planetary gear causing impact damage to the bearing during the assembly process.

[0038] Please refer to Figure 1 A bearing clamp includes a support rod 1, a locking assembly 2, a connecting rod assembly 3, and a chuck assembly 4.

[0039] Specifically, the locking assembly 2 is sleeved on the support rod 1 so that the locking assembly 2 can move axially along the support rod 1; the connecting rod assembly 3 is sleeved on the end of the support rod 1, can move axially along the support rod 1, and abuts against the locking assembly 2; the chuck assembly 4 is connected to the connecting rod assembly 3 radially along the support rod 1, and moves radially along the support rod 1 to abut against or move away from the inner hole of the bearing.

[0040] The bearing clamp designed in the above manner moves the connecting rod assembly 3 along the axial direction of the support rod 1, thereby driving the chuck assembly 4 to extend and retract radially in the support rod 1. This enables the chuck assembly 4 to abut against and separate from the bearing inner hole, thus achieving horizontal installation of the bearing and avoiding impact damage to the bearing caused by the planetary gears during assembly.

[0041] In the above embodiment, the linkage assembly 3 includes a fixed block 31, a sliding block 32, and a connecting rod 33. The fixed block 31 is fixedly sleeved on the end of the support rod 1, the sliding block 32 is sleeved on the circumference of the support rod 1 and can slide along the axial direction of the support rod 1, the end face of the sliding block 32 abuts against the locking assembly 2, and the position of the sliding block 32 is fixed by the locking assembly 2. The connecting rod 33 connects the fixed block 31, the sliding block 32, and the clamp assembly 4 so that the sliding block 32 can move along the axial direction of the support rod 1, thereby driving the clamp assembly 4 to move in the radial direction of the support rod 1.

[0042] It should be noted that the movement of the sliding block 32 drives the movement of the connecting rod 33, thereby changing the radial dimension of the chuck assembly 4 along the support rod 1. When the sliding block 32 is pulled backward, it causes the connecting rod 33 to contract radially along the support rod 1, so that the diameter of the cylindrical surface formed by the chuck assembly 4 becomes smaller, allowing the chuck assembly 4 to be inserted into the inner hole of the bearing. Subsequently, the sliding block 32 is pushed forward, causing the connecting rod 33 to extend radially along the support rod 1, so that the diameter of the cylindrical surface formed by the chuck assembly 4 becomes larger, allowing the chuck assembly 4 to be pressed tightly against the inner hole of the bearing.

[0043] In the above case, the locking assembly 2 includes a collar bolt 21 and a spring 22; the collar bolt 21 is sleeved on the support rod 1 along the circumference of the support rod 1, and the end of the spring 22 abuts against the collar bolt 21 and the sliding block 32 respectively.

[0044] It is understandable that the ends of the spring 22 abut against the collar bolt 21 and the sliding block 32 respectively, which can prevent the collar bolt 21 from contacting the chuck assembly 4, thereby preventing the collar bolt 21 from interfering with the chuck assembly 4 and thus affecting the operation of the chuck assembly 4.

[0045] Furthermore, once the sliding block 32 has moved to a certain position, it is locked by the collar bolt 21 and the spring 22 to prevent the sliding block 32 from moving when the chuck assembly 4 is working.

[0046] In real-world applications, the spring 22 can also be replaced with other components, as long as the aforementioned technical effects can be achieved.

[0047] In the above embodiment, three sets of connecting rods 33 are provided, and the three sets of connecting rods 33 are evenly arranged along the circumference of the support rod 1.

[0048] It should be noted that each set of connecting rods 33 is connected to the sliding block 32, the fixed block 31 and the chuck assembly 4. The three sets of connecting rods 33 are evenly arranged along the circumference of the support rod 1 and can move synchronously along the radial direction of the support rod 1, so that the process of the chuck assembly 4 abutting against or leaving the bearing inner hole is more stable.

[0049] Furthermore, three sets of clamp assemblies 4 are evenly arranged along the circumference of the support rod 1, and the three sets of clamp assemblies 4 are connected to the three sets of connecting rods 33 in a one-to-one correspondence.

[0050] It is understandable that the clamp assembly 4 is provided in three sets, and the three sets of clamp assemblies 4 are evenly arranged around the support rod 1. One set of clamp assemblies 4 is connected to one set of connecting rods 33.

[0051] Based on the above embodiments, the chuck assembly 4 includes a chuck 41, a positioning block 42, and a bolt 43; the chuck 41 is connected to the connecting rod 33, the positioning block 42 is located at the head of the chuck 41, and the bolt 43 is located at the end of the chuck 41 to lock the bearing.

[0052] It should be noted that loosening the collar bolt 21 and pulling the sliding block 32 backward causes the connecting rod 33 to retract radially along the support rod 1, thereby reducing the diameter of the cylindrical surface formed by the three sets of chuck assemblies 4, so that the chuck assembly 4 can be inserted into the inner hole of the bearing. Then, the sliding block 32 is pushed forward, causing the connecting rod 33 to extend radially along the support rod 1, thereby increasing the diameter of the cylindrical surface formed by the chuck assembly 4. The positioning block 42 abuts against the inner wall of the bearing. The collar bolt 21 is tightened to fix the sliding block 32 in the axial position. The bolt 43 set at the end of the chuck 41 is tightened to abut against the end face of the bearing to fix the bearing.

[0053] In the above embodiments, any one of the clamps 41 is provided with a lifting rod 44, and the lifting rod 44 is provided with a screw hole.

[0054] It is understandable that the lifting is carried out through the screw holes on the lifting rod 44. The lifting rod 44 has screw holes in different positions to balance the lifting. After lifting, hold the support rod 1 and slowly install the bearing by aligning it with the planetary gear hole.

[0055] As a preferred embodiment, the positioning block 42 is provided with a U-shaped groove.

[0056] It should be noted that the positioning block 42 has a U-shaped groove, which can be used to adjust the size of the positioning block 42. If the size of the positioning block 42 is too small, a larger positioning block 42 can be replaced.

[0057] In the above case, the end face of the positioning block 42 that abuts against the bearing is set as a conical surface.

[0058] Understandably, the end face of the positioning block 42 that abuts against the bearing is set as a conical surface, with the small end facing inward. The three positioning blocks 42 form a cone to achieve positioning. The size of the positioning block 42 is slightly smaller than the diameter of the bearing, thereby enabling the bearing to be installed smoothly.

[0059] In summary, the bearing fixture provided by this invention allows for the following steps during planetary gear bearing assembly: the planetary gear is placed horizontally on a platform, the bearing fixture is pressed against the inner hole of the bearing, the bearing fixture is lifted using a tooling, the bearing is leveled and aligned with the planetary gear bearing hole, the first bearing is installed, the bearing fixture is removed, a spacer ring is installed, the second bearing is lifted, leveled and aligned, the bearing fixture is removed, and the bearing is manually pushed in to achieve proper assembly, thus completing the planetary gear bearing assembly.

[0060] Specifically, loosening the collar bolt 21 causes the three sets of connecting rods 33 to automatically retract, reducing the diameter of the cylindrical surface formed by the three clamps 41. This allows them to be inserted into the bearing's inner hole. Pushing the sliding block 32 forward causes the three sets of connecting rods 33 to move synchronously, increasing the diameter of the cylindrical surface formed by the three clamps 41 to secure the bearing's inner hole. The three positioning blocks 42 at the heads of the three clamps 41 form a cone for positioning; their size is slightly smaller than the bearing's diameter, thus facilitating the bearing's smooth installation. Tightening the collar bolt 21 locks the clamps 41 to the bearing. Additionally, tightening the bolts 43 on the end face of the clamps 41 presses the bearing, completely fixing it in place. Lift the bearing by using the screw hole of the lifting rod 44 on one of the chucks 41. After lifting, hold the support rod 1 and slowly insert it into the planetary gear hole. During the bearing installation process, once most of the bearing is inserted into the inner hole of the planetary gear bearing, cut the rubber band on the outer circle of the bearing. After the bearing is installed, loosen the bolt 43 on the chuck 41 and the collar bolt 21 on the support rod 1. The connecting rod 33 will automatically retract, and the cylindrical surface formed by the three chucks 41 will become smaller, allowing it to be removed. When installing the second bearing, due to interference from the middle spacer ring, the bearing cannot be assembled into place in one go. The bearings are already in the inner hole and fixed. After removing the bearing fixture, manually push the bearing inward to assemble it into place.
