Description

Technical Field

[0001] This utility model relates to the field of bearing grease equalization, and in particular to a double grease equalization mechanism suitable for bearings of different specifications. Background Technology

[0002] During the manufacturing process of bearings, in order to ensure the proper operation and service life of the bearings, it is necessary to apply grease evenly. This reduces friction, lowers temperature rise, and extends bearing life. For rolling bearings, grease application is a necessary step before they are put into use. After applying grease, to prevent uneven grease distribution, the inner and outer rings of the bearing need to be rotated to a certain extent to ensure even grease distribution inside the bearing.

[0003] However, existing bearing grease leveling equipment can only rotate the outer circumference or inner ring of the bearing when rotating it. To achieve a good grease leveling effect, it requires more time and manpower. Furthermore, for bearings with different outer diameters, inner diameters, and thicknesses, there may be a need to change different tooling fixtures, making the operation cumbersome and inefficient.

[0004] Therefore, we propose a double grease-mixing mechanism applicable to bearings of different specifications. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a dual grease-leveling mechanism suitable for bearings of different specifications. Through the relatively arranged anti-slip clamps, the bearing is simultaneously clamped from the outer circumference and inner ring, which can adapt to different outer and inner diameter specifications. The elastic deformation of the spring allows the anti-slip clamps to automatically adapt to bearings of different thicknesses or sizes. In addition, the relative rotation of the sleeve and the shaft allows the outer and inner limiting rings to rotate independently, and with the cooperation of the second and third bevel gears, the power transmission direction is changed, realizing differentiated rotation of the two, enhancing the uniformity of grease distribution, and improving grease-leveling efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A double grease-leveling mechanism suitable for bearings of different specifications includes a drive assembly, the top of which is provided with a clamping assembly; the clamping assembly includes an outer limiting ring, and an inner limiting ring is provided inside the outer limiting ring. The tops of the outer limiting ring and the inner limiting ring are slidably connected to multiple equally spaced sliders, and the tops of the sliders are fixedly connected to anti-slip clamping blocks. The sliders and anti-slip clamping blocks on the outer limiting ring are arranged in opposite directions to the sliders and anti-slip clamping blocks on the inner limiting ring.

[0008] Furthermore, a movable rod is fixedly connected to one end of the slider, and a limiting cylinder is slidably connected to the end of the movable rod away from the slider. A spring that is fixedly connected to the movable rod is fixedly connected inside the limiting cylinder.

[0009] Furthermore, the top ends of both the outer and inner limiting rings are provided with sliding grooves adapted to the slider, and the sliding grooves are fixedly connected to the limiting cylinder.

[0010] Furthermore, the drive assembly includes a housing, a bracket is fixedly connected inside the housing, a shaft is rotatably connected inside the bracket, and the top end of the shaft passes through the top end of the bracket and the housing and is fixedly connected to an inner limiting ring.

[0011] Furthermore, a sleeve that is rotatably connected to the bracket is rotatably connected to the middle part of the shaft, a third bevel gear is fixedly connected to the bottom end of the sleeve, and a connecting rod that is fixedly connected to the outer limiting ring is fixedly connected to the top end of the shaft through the top end of the outer shell.

[0012] Furthermore, a second bevel gear is fixedly connected to the bottom end of the shaft and inside the bracket.

[0013] Furthermore, a motor is fixedly connected to the outer wall of the bracket, and the transmission end of the motor passes through the inner wall of the bracket and is fixedly connected to a first bevel gear that meshes with the second bevel gear and the third bevel gear.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. With the anti-slip clamping blocks set in opposite directions, the bearing can be clamped from both the outer circumference and the inner ring at the same time, which can accommodate bearings with different outer and inner diameters; the equidistant distribution of multiple sets of sliders ensures uniform clamping force and prevents the bearing from shifting during the grease application process.

[0016] 2. By utilizing the elastic deformation of the spring, the anti-slip clamping block can automatically adapt to bearings of different thicknesses or sizes. The sliding cooperation between the movable rod and the limiting cylinder restricts the movement range of the slider, ensuring clamping stability.

[0017] 3. The outer and inner limiting rings can rotate independently through the relative rotation of the sleeve and the shaft; the transmission of the second and third bevel gears changes the direction of power transmission, realizing differentiated rotation of the outer and inner limiting rings, such as reverse rotation, which enhances the uniformity of oil distribution and improves the oil-leveling efficiency during oil leveling.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] Reference Figures 1 to 5 As shown, this is a preferred embodiment of the present invention of a double grease-balancing mechanism for bearings of different specifications, including a drive assembly 1, and a clamping assembly 2 at the top of the drive assembly 1; the clamping assembly 2 includes an outer limiting ring 201, an inner limiting ring 202 is provided inside the outer limiting ring 201, and a plurality of equally spaced sliders 206 are slidably connected to the top of both the outer limiting ring 201 and the inner limiting ring 202, and an anti-slip clamping block 207 is fixedly connected to the top of the sliders 206; the sliders 206 and the anti-slip clamping block 207 on the outer limiting ring 201 are arranged in opposite directions to the sliders 206 and the anti-slip clamping block 207 on the inner limiting ring 202.

[0027] The anti-slip clamping blocks 207 are arranged in opposite directions, and the bearing can be clamped from the outer circumference and inner ring at the same time, which can accommodate bearings with different outer and inner diameters. The equidistant distribution of multiple sets of sliders 206 ensures uniform clamping force and prevents the bearing from shifting during the grease application process.

[0028] One end of the slider 206 is fixedly connected to a movable rod 204, and the end of the movable rod 204 away from the slider 206 is slidably connected to a limiting cylinder 203. A spring 205 fixedly connected to the movable rod 204 is fixedly connected inside the limiting cylinder 203.

[0029] The elastic deformation of the spring 205 allows the anti-slip clamping block 207 to automatically adapt to bearings of different thicknesses or sizes, providing buffer clamping force and preventing bearing damage caused by rigid clamping; the sliding cooperation between the movable rod 204 and the limiting cylinder 203 limits the movement range of the slider 206, ensuring clamping stability.

[0030] The top of both the outer limiting ring 201 and the inner limiting ring 202 are provided with a sliding groove adapted to the slider 206, and the sliding groove is fixedly connected to the limiting cylinder 203.

[0031] The guide effect of the slide groove ensures that the slider 206 slides smoothly along a straight line, preventing the anti-slip clamping block 207 from tilting during clamping; the fixed connection between the limiting cylinder 203 and the slide groove ensures that the installation position of the spring 205 is stable and maintains the consistency of the elastic clamping force.

[0032] The drive assembly 1 includes a housing 101, a bracket 102 is fixedly connected inside the housing 101, and a shaft 105 is rotatably connected inside the bracket 102. The top end of the shaft 105 passes through the top end of the bracket 102 and the housing 101 and is fixedly connected to the inner limiting ring 202.

[0033] The motor 103 drives the shaft 105 to rotate, which in turn drives the inner limit ring 202 to rotate, providing basic power for the bearing grease distribution; the fixed support of the bracket 102 ensures the coaxiality of the shaft 105 when it rotates, and avoids shaking during power transmission.

[0034] A sleeve 106 rotatably connected to the bracket 102 is rotatably connected to the middle part of the shaft 105. A third bevel gear 109 is fixedly connected to the bottom end of the sleeve 106. The top end of the shaft 105 passes through the top end of the outer shell 101 and is fixedly connected to a connecting rod 107 fixedly connected to the outer limiting ring 201.

[0035] The relative rotation between the sleeve 106 and the shaft 105 allows the outer limiting ring 201 and the inner limiting ring 202 to rotate independently; the transmission of the third bevel gear 109 changes the direction of power transmission, realizing differentiated rotation of the outer limiting ring 201 and the inner limiting ring 202, such as reverse rotation, which enhances the uniformity of oil distribution and improves the oil-washing efficiency during oil-washing.

[0036] A second bevel gear 108 is fixedly connected to the bottom end of the shaft 105 and inside the bracket 102;

[0037] The second bevel gear 108 can drive the shaft 105 to rotate.

[0038] A motor 103 is fixedly connected to the outer wall of the bracket 102. The transmission end of the motor 103 passes through the inner wall of the bracket 102 and is fixedly connected to a first bevel gear 104 that meshes with the second bevel gear 108 and the third bevel gear 109.

[0039] The motor 103 provides stable power to the shaft 105 and sleeve 106 through the meshing of the first bevel gear 104 with the second bevel gear 108 and the third bevel gear 109, ensuring the rotation of the outer limit ring 201 and the inner limit ring 202, thereby achieving effective grease distribution on the bearing.

[0040] Specific implementation process: First, place the bearing to be greased in the clamping assembly 2. The inner ring of the bearing contacts the anti-slip clamping block 207 on the inner limiting ring 202, and the outer ring of the bearing contacts the anti-slip clamping block 207 on the outer limiting ring 201. During placement, because the movable rod 204 at one end of the slider 206 is connected to the spring 205 inside the limiting cylinder 203, the spring 205 will elastically deform according to the size of the bearing, so that the anti-slip clamping block 207 tightly fits the inner and outer rings of the bearing, realizing adaptive clamping for bearings of different specifications. Then, start the motor 103. The transmission end drives the first bevel gear 104 to rotate. The first bevel gear 104 simultaneously meshes with the second bevel gear 108 and the third bevel gear 109. The second bevel gear 108 drives the shaft 105 to rotate, thereby causing the inner limiting ring 202 to rotate. The third bevel gear 109 drives the sleeve 106 to rotate, and through the connecting rod 107, causes the outer limiting ring 201 to rotate. The outer limiting ring 201 and the inner limiting ring 202 can rotate differently. During the rotation of the bearing, in conjunction with the external grease-spreading device, the grease is evenly applied to the raceway and balls of the bearing, completing the grease-spreading operation of the bearing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
