Description

Technical Field

[0001] This utility model relates to the field of pushing device technology, and in particular to a pushing device for bearing installation. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. When a bearing is fixed on a fixed shaft, it is not easy to move the bearing on the fixed shaft. Nowadays, the bearing is pushed to the designated position on the fixed shaft by manually using tools to knock it. The operation is time-consuming and labor-intensive, and it is easy to damage the bearing. Utility Model Content

[0003] This utility model discloses a pushing device for bearing installation, which solves the problem that using tools to push the bearing to a designated position on a fixed shaft by tapping is time-consuming and laborious, and can easily damage the bearing.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A bearing mounting pusher includes a lifting ring, a fixed ring above the lifting ring, a set of bearing blocks arranged in a circular array inside the fixed ring, a spring fixed between the bearing blocks and the inner wall of the fixed ring, a limiting rod penetrating the fixed ring fixed on the bearing blocks, and an L-shaped plate fixed at the bottom of the bearing blocks; a connecting ring threaded to the inner wall of the fixed ring is fixed at the top of the lifting ring, and a movable ring with an inner diameter decreasing from top to bottom is fixed on the inner wall of the connecting ring, with the end of the L-shaped plate away from the bearing blocks contacting the inner wall of the movable ring; a support rod is fixed on the fixed ring, a support frame is fixed at the other end of the support rod, a hydraulic rod is fixed on the support frame, a slider slidably connected to the support rod is fixed at the telescopic end of the hydraulic rod, a connecting rod is fixed at the bottom of the slider, and a sleeve is fixed at the other end of the connecting rod.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] First, the bearing is fitted onto the fixed shaft. Then, depending on the size of the bearing, the lifting ring is rotated, causing the connecting ring to move the moving ring upwards. After the moving ring moves upwards, it can stretch the No. 1 spring by squeezing the L-shaped plate, causing the limiting rod to move inwards towards the fixed ring, thus moving the bearing block. Once the position of a set of bearing blocks is adjusted, the bearing can be placed inside the fixed ring, allowing the bearing blocks to support it. Then, the hydraulic rod is activated, causing the slider to move downwards via the connecting rod, allowing the end of the fixed shaft to enter the sleeve. The sleeve continues to move downwards, pushing the fixed shaft downwards, thus completing the operation of installing the bearing in the designated position on the fixed shaft. This invention can quickly install the bearing in the designated position on the fixed shaft. The operation is simple and fast, requiring no manual operation by personnel, and will not damage the bearing. Attached Figure Description

[0012] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 and Figure 2As shown, this utility model provides a pushing device for bearing installation, including a lifting ring 1, a fixed ring 2 above the lifting ring 1, a set of bearing blocks 4 arranged in a ring array inside the fixed ring 2, a spring 41 fixed between the bearing blocks 4 and the inner wall of the fixed ring 2, a limiting rod 42 penetrating the fixed ring 2 fixed on the bearing blocks 4, and an L-shaped plate 43 fixed at the bottom of the bearing blocks 4; a connecting ring 5 threadedly connected to the inner wall of the fixed ring 2 fixed at the top of the lifting ring 1, a moving ring 51 with an inner diameter decreasing from top to bottom fixed on the inner wall of the connecting ring 5, and the end of the L-shaped plate 43 away from the bearing blocks 4 contacting the inner wall of the moving ring 51; a support rod 7 fixed on the fixed ring 2, a support frame 71 fixed at the other end of the support rod 7, a hydraulic rod 72 fixed on the support frame 71, a slider 73 slidably connected to the support rod 7 fixed at the telescopic end of the hydraulic rod 72, a connecting rod 8 fixed at the bottom of the slider 73, and a sleeve 81 fixed at the other end of the connecting rod 8. Depending on the size of the bearing, rotating the lifting ring 1 causes the connecting ring 5 to move the moving ring 51 upwards, pressing the inner wall of the moving ring 51 against the end of a set of L-shaped plates 43, stretching the first spring 41. The limiting rod 42 and the bearing block 4 then move towards the axis inside the fixed ring 2. After adjusting the position of the set of bearing blocks 4, the bearing is sleeved on the fixed shaft and then placed into the fixed ring 2, where the set of bearing blocks 4 supports the bearing. Then, the hydraulic rod 72 is activated to slide the slider 73 downwards (there are two hydraulic rods 72 and two support rods 7), causing the connecting rod 8 to move the sleeve 81 downwards, allowing the end of the fixed shaft to enter the sleeve 81. As the sleeve 81 continues to move downwards, the fixed shaft can be pushed downwards, completing the operation of installing the bearing in the designated position on the fixed shaft. The set of bearing blocks 4 allows for the support of different bearing models by adjusting the position of the bearing blocks 4 according to the size of the bearing.

[0014] like Figure 1 and Figure 2 As shown, a set of slidingly connected abutment rods 21 pass through the fixed ring 2. A connecting block 22 is fixed to one end of the abutment rod 21 outside the fixed ring 2. A second spring 23 is fixed between the connecting block 22 and the fixed ring 2. A slidingly connected sleeve 3 is fitted on the fixed ring 2. An annular block 31 with its inner wall in contact with the connecting block 22 is fixed inside the sleeve 3. The inner diameter of the annular block 31 increases from top to bottom. An annular ring 32 with a threaded connection to the fixed ring 2 is rotatably connected to the bottom of the sleeve 3. When the bearing is placed on a set of bearing blocks 4, the annular ring 32 can be rotated to make the sleeve 3 move the annular block 31 downward. The annular block 31 can then squeeze the connecting block 22, compressing the second spring 23. The abutment rods 21 move towards the outer wall of the bearing, thus holding the bearing in place. After the set of abutment rods 21 hold the outer wall of the bearing, the fixing effect of the bearing can be increased, making the bearing more firmly fixed, so that the bearing can be installed in the designated position on the fixed shaft later.

[0015] like Figure 1 and Figure 2 As shown, a rubber pad 24 is fixed to one end of the abutment 21 near the axis of the fixed ring 2; a short rod 33 is fixed to the annular ring 32. The rubber pad 24 can increase the friction between the abutment 21 and the bearing; the short rod 33 makes it easier for the operator to rotate the annular ring 32.

[0016] like Figure 3 As shown, a baffle 6 is threadedly connected to the inner side of the lifting ring 1. The baffle 6 is designed so that, depending on the distance the fixed shaft needs to move downward, the baffle 6 can be rotated so that when the bearing is installed in place, the bottom end of the fixed shaft contacts the baffle 6, and the baffle 6 serves a positioning function.

[0017] like Figure 1 As shown, a base 9 is fixed to the bottom of the support frame 71, and the lifting ring 1 is located above the base 9. The base can increase the stability of the support frame 71.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
