Description

Technical Field

[0001] The utility model relates to the field of grease permeation after grease injection of bearings, in particular to an improved grease permeation machine. Background Art

[0002] Grease needs to be injected into the bearing. In order to evenly distribute the grease in the bearing, a grease-permeating machine will be used to grease the bearing after grease injection. In the Chinese utility model patent with the authorization announcement date of 2024.03.08 and the authorization announcement number of CN220567044U, a bearing grease adding and grease-permeating device is disclosed. The cylinder pressure is used to push the grease injection sleeve close to the bearing to be greased. At the same time, the internal baffle of the grease injection sleeve drives the linear bearing to move downward, so that the rotating seat is pressed on the inner ring of the bearing to be greased; after the grease injection is completed, the motor is started, and the central shaft and the rotating seat are driven to rotate through the motor, the first transmission gear and the second transmission gear. The rotation of the rotating seat drives the inner ring of the bearing to be greased, the rolling element and the retaining frame of the bearing to be greased to rotate, so that the injected grease can be evenly distributed in the bearing raceway. However, the drive of the rotating seat requires a motor and a two-stage transmission gear, which has a complex structure and occupies a relatively large space. There is no limit structure for the lifting and lowering of the rotating seat. When the spring gives the inner ring of the bearing to be greased an appropriate axial preload, once the spring loses its elasticity or cannot be reset, the inner ring of the bearing cannot be pressed, affecting the grease quality. Utility Model Content

[0003] In order to overcome the above shortcomings, the purpose of the utility model is to provide an improved grease-allowing machine which has a simple structure, occupies a small area, provides lifting and lowering limits for the rotating seat, and ensures uniform grease-allowing of the bearing.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: an improved grease-permitting machine, comprising: a coupling sleeve, which has an axial through hole inside, and a lower transverse slot hole connected to the axial through hole is arranged on the lower end side wall of the coupling sleeve; a lower transverse pressure block, which is locked and fixed in the lower transverse slot hole with a matching shape; a telescopic shaft, which is slidably arranged at the lower end of the axial through hole through a linear bearing and extends out of the axial through hole, and a limiting slot is arranged on the side wall of the telescopic shaft, and the width of the limiting slot is greater than the width of the lower transverse pressure block. When the telescopic shaft is raised or lowered, the upper and lower side walls of the limiting slot can be respectively limited by the upper and lower end faces of the lower transverse pressure block; a spring, which is arranged in the axial through hole and located at the top of the telescopic shaft; a rotating seat, which is fixed at the bottom of the telescopic shaft; a motor, whose output shaft is connected and fixed to the top of the coupling sleeve; a cylinder, which drives the motor to rise and fall.

[0005] The beneficial effects of the improved fat-permeating machine of the utility model are:

[0006] Firstly, when the cylinder drives the motor, the coupling sleeve, the telescopic shaft and the rotating seat to move down together until the rotating seat reaches the inner ring of the bearing, the motor at the top drives the rotating seat to rotate through the coupling sleeve, thereby evenly shaking the grease in the bearing, eliminating the gear transmission, and the motor is driven from top to bottom, which occupies a small area and has a simple structure, making it easy to install the improved grease machine on a bearing assembly machine with a small installation space.

[0007] Secondly, the spring provides a buffering effect when the rotating seat just contacts the inner ring of the bearing to be greased, that is, the rotating seat and the coupling sleeve can move relative to each other to prevent the rotating seat from crushing the inner ring of the bearing; at the same time, when the telescopic shaft is lifted and lowered, the upper and lower side walls of its limit groove are limited by the lower lateral pressure block of the coupling sleeve, and the lower lateral pressure block provides a limit for the lifting and lowering of the rotating seat, giving an extreme position to ensure that the rotating seat can press the inner ring of the bearing and ensure the uniformity of the bearing grease.

[0008] Preferably, the axial through hole is in a stepped shape with the upper end diameter being smaller than the lower end diameter, and the upper end of the spring abuts against the step surface of the axial through hole, so as to provide an upper limit for the telescopic shaft and an installation environment for the spring.

[0009] Preferably, the upper end of the telescopic shaft is concavely provided with a mounting groove, and the lower end of the spring is located in the mounting groove. The lower end of the spring is located inside the telescopic shaft, ensuring that the spring can be stably compressed and release elastic force in the axial direction.

[0010] Preferably, the bottom of the rotating seat is in a frustum shape, matching the inner ring of the bearing to be greased.

[0011] Preferably, it includes a support column, which is provided with a bracket through the cooperation and sliding of a longitudinal slide rail and a slider, the motor is fixed on the bracket, and its output shaft faces downward and passes through the bracket, and the cylinder is fixed on the support column to drive the bracket to rise and fall.

[0012] Preferably, the cylinder is connected and fixed to the bracket via a floating joint. The floating joint connection is adopted to reduce the eccentricity of the cylinder.

[0013] Preferably, the output shaft is inserted into the upper end of the axial through hole, and the upper end of the coupling sleeve is provided with an upper transverse slot hole, the upper transverse slot hole is connected with the axial through hole, an upper transverse pressure block is clamped in the upper transverse slot hole, and the upper transverse pressure block is fixed to the coupling sleeve by bolts and clamps the output shaft.

[0014] Preferably, the side of the output shaft clamped by the upper transverse pressing block is a plane, and the two are clamped by surface contact. The surface contact clamping method is adopted so that the upper transverse pressing block can stably clamp the output shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] See also Figure 1-Figure 10 As shown, this embodiment discloses an improved grease-permitting machine, including a coupling sleeve 10, which has an axial through hole 11 inside, and a lower transverse slot 12 connected to the axial through hole 11 is arranged on the lower end side wall of the coupling sleeve 10; a lower transverse pressing block 20, which is locked and fixed in the lower transverse slot 12 with a matching shape; a telescopic shaft 30, which is slidably arranged at the lower end of the axial through hole 11 through a linear bearing 31, and extends out of the axial through hole 11, and a limiting groove 32 is arranged on the side wall of the telescopic shaft 30 The width of the limit groove 32 is greater than the width of the lower transverse pressing block 20. When the telescopic shaft 30 is lifted or lowered, the upper and lower side walls 32a and 32b of the limit groove 32 can be respectively limited by the upper and lower end surfaces 20a and 20b of the lower transverse pressing block 20; the spring is arranged in the axial through hole 11 and is located at the top of the telescopic shaft 30; the rotating seat 40 is fixed at the bottom of the telescopic shaft 30; the motor 50, whose output shaft 51 is connected and fixed to the top of the coupling sleeve 10; the cylinder 60 drives the motor 50 to lift or lower.

[0037] The axial through hole 11 is in a stepped shape with the upper end diameter smaller than the lower end diameter. The upper end of the spring abuts against the step surface of the axial through hole 11 . The upper end of the telescopic shaft 30 is concavely provided with a mounting groove 33 , and the lower end of the spring is located in the mounting groove 33 .

[0038] The bottom of the rotating seat 40 in this embodiment is in a frustum shape, which matches the inner ring of the bearing 90 to be greased.

[0039] The improved fat-permeating machine also includes a support column 70, which is provided with a bracket 73 through the cooperation and sliding of a longitudinal slide rail 71 and a slider 72. The motor 50 is fixed on the bracket 73, and its output shaft 51 faces downward and passes through the bracket 73. The cylinder 60 is fixed on the support column 70 to drive the bracket 73 to rise and fall, wherein the cylinder 60 is connected and fixed to the bracket 73 through a floating joint 61.

[0040] The output shaft 51 is inserted into the upper end of the axial through hole 11. The upper end of the coupling sleeve 10 is provided with an upper transverse slot 13, which is communicated with the axial through hole 11. An upper transverse pressing block 80 is clamped in the upper transverse slot 13. The upper transverse pressing block 80 is fixed to the coupling sleeve 10 by bolts and clamps the output shaft 51. The side of the output shaft 51 clamped by the upper transverse pressing block 80 is a plane 52, and the two are clamped by surface contact.

[0041] The working principle of this embodiment is:

[0042] The cylinder 60 drives the bracket 73 to descend, and the motor 50 on the bracket 73 drives the shaft sleeve 10, the telescopic shaft 30, and the rotating seat 40 to move downward together until the rotating seat 40 reaches the inner ring of the bearing 90 to be greased. The motor 50 at the top drives the shaft sleeve 10 to rotate through the upper transverse pressing block 80, and the rotating seat 40 fixed at the lower end of the shaft sleeve 10 also rotates accordingly, and then the grease in the bearing 90 to be greased is shaken evenly. When the rotating seat 40 just reaches the inner ring of the bearing 90 to be greased, the rotating seat 40 and the telescopic shaft 30 move upward accordingly, and the spring is compressed until the lower side wall 32b of the limiting groove 32 is limited by the lower end surface 20b of the lower transverse pressing block 20, at which time, the rotating seat 40 and the telescopic shaft 30 stop moving upward.

[0043] After grease is allowed, the cylinder 60 drives the bracket 73 to rise, and the motor 50 on the bracket 73 drives the connecting sleeve 10, the telescopic shaft 30, and the rotating seat 40 to move up together. The rotating seat 40 releases the inner ring of the bearing after grease is allowed, and the spring resets, forcing the telescopic shaft 30 and the rotating seat 40 to move downward until the upper side wall 32a of the limiting groove 32 is restricted by the upper end surface 20a of the lower transverse pressure block 20, and the telescopic shaft 30 and the rotating seat 40 stop moving downward.

It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
