Description

Technical Field

[0001] The utility model relates to the field of shaft sleeves, in particular to a mounting assembly and a shaft sleeve. Background Art

[0002] In current mechanical transmission systems, the installation of the sleeve is usually a key step, which is directly related to the working performance and life of the mechanical equipment. However, traditional sleeve installation methods often have many shortcomings.

[0003] First, the traditional installation method mainly relies on manual labor to directly press the sleeve into the inner ring of the bearing. This method requires high skills from the operator, has low installation efficiency, and is prone to loose fit between the sleeve and the bearing due to inaccurate installation. Secondly, due to possible uncertainties in the installation process, such as the operator's technical level, the temperature and humidity of the installation environment, etc., the gap between the sleeve and the bearing may be too large or too small, which in turn affects the operating stability and accuracy of the mechanical equipment. In addition, the traditional installation method is also prone to wear between the shaft and the bearing due to loose installation. During long-term operation, this wear will gradually intensify, resulting in a decline in the performance of the mechanical equipment and even causing failures.

[0004] Therefore, developing a new type of sleeve installation assembly to achieve fast and stable installation of the sleeve on the inner ring of the bearing is of great significance for improving the performance and service life of mechanical equipment. Utility Model Content

[0028] Embodiment 2

[0029] See attached Figures 5 to 9As shown, on the basis of Example 1, in order to realize the installation splint 1 being sleeved and fixed on the shaft sleeve body 2, the slide groove 4 is a "Zhong"-shaped groove, and two slide grooves 4 are provided. The two slide grooves 4 are symmetrically distributed about the pipe mouth of the shaft sleeve body 2, and the slider 3 is a "Zhong"-shaped block, and the slider 3 is slidably connected in the slide groove 4; the surface of the slide groove 4 is provided with an embedding groove 5, and the long side length of the embedding groove 5 is equal to the long side length of the slide groove 4, and a rubber gasket 6 is fixed on the surface of the embedding groove 5, and the thickness of the rubber gasket 6 is less than the depth of the embedding groove 5, and the thickness of the connecting piece 7 is less than the thickness of the slider 3, and the brake screw 8 clamps the rubber gasket 6 after being locked.

[0030] Insert the sleeve body 2 into the inner ring from one end of the bearing, then sleeve the mounting clamp 1 on one end of the sleeve body 2, push the mounting clamp 1 to move toward the bearing, and pull the slider 3 along the slide groove 4 when the mounting clamp 1 slides. When the mounting clamp 1 and the end plate of the sleeve body 2 clamp the inner ring of the bearing, screw the brake screw 8 to lock and clamp the rubber gasket 6 to prevent the mounting clamp 1 from sliding. The sleeve body 2 is then installed on the inner ring of the bearing, and the shaft body is inserted into the sleeve body 2. The sleeve body 2 is between the inner ring of the bearing and the shaft body to prevent wear between the shaft body and the bearing.

[0031] Embodiment 3

[0032] See attached Figure 8 On the basis of the second embodiment, in order to prevent the locked brake screw 8 from loosening, a receiving groove 9 is opened on the surface of the slider 3, and the notch of the receiving groove 9 and the connecting piece 7 are on the same side of the slider 3. A baffle 10 is inserted into the inside of the receiving groove 9, and a rubber support plate 11 is fixed between the baffle 10 and the receiving groove 9. In the initial state, the rubber support plate 11 blocks one side of the locked brake screw 8; a rubber gasket 12 is fixed on the side of the mounting splint 1 facing the end plate of the sleeve body 2, and a rubber gasket 2 13 is fixed on the surface of the end plate of the sleeve body 2, and the rubber gasket 2 13 is opposite to the rubber gasket 12.

[0033] It should be noted that when installing the brake screw 8, it is necessary to squeeze the baffle 10 and retract it into the receiving groove 9. At this time, the baffle 10 squeezes the rubber support plate 11 to produce elastic deformation, and the baffle 10 retracted into the receiving groove 9 no longer blocks the brake screw 8 from being screwed on the connecting plate 7. After the brake screw 8 is locked, the baffle 10 is released. At this time, the rubber support plate 11 rebounds and pushes the baffle 10 out of the receiving groove 9, and the part of the baffle 10 extending out of the receiving groove 9 blocks one side of the brake screw 8 to prevent the brake screw 8 from loosening, thereby ensuring that the end plate of the installation clamp 1 and the sleeve body 2 tightly clamps the inner ring of the bearing.

[0034] Embodiment 4

[0035] Based on the third embodiment, a shaft sleeve is proposed, including a mounting assembly.

[0036] When in use, insert the sleeve body 2 into the inner ring from one end of the bearing, then sleeve the mounting clamp 1 on one end of the sleeve body 2, push the mounting clamp 1 to move toward the bearing, and when the mounting clamp 1 slides, the traction slider 3 slides along the slide groove 4. When the mounting clamp 1 and the end plate of the sleeve body 2 clamp the inner ring of the bearing, screw the brake screw 8 to lock and clamp the rubber gasket 6 to prevent the mounting clamp 1 from sliding. The sleeve body 2 is then installed on the inner ring of the bearing, and the shaft body is inserted into the sleeve body 2. The sleeve body 2 is between the inner ring of the bearing and the shaft body to prevent wear between the shaft body and the bearing. The part of the baffle 10 extending out of the storage groove 9 blocks one side of the brake screw 8 to prevent the brake screw 8 from loosening, thereby ensuring that the end plate of the mounting splint 1 and the sleeve body 2 tightly clamp the inner ring of the bearing.
