Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a dustproof sealing bearing. Background Art

[0002] Dust-proof sealed bearings are bearings with a special sealing structure that can effectively prevent the intrusion of dust, moisture and other foreign matter while retaining lubricant, thereby extending the service life of the bearing and improving performance.

[0003] For example, a Chinese patent with publication number CN210509975U discloses a dustproof sealed bearing, including a bearing body, an outer ring end of the bearing body is detachably connected to a dust cover through a clamping mechanism, a heat dissipation device is provided on the surface of the dust cover, a first folded edge is fixed at the bottom edge of the dust cover, a second folded edge is provided at the inner ring edge of the bearing body corresponding to the position of the first folded edge, the second folded edge is an L-shaped structure, the second folded edge is close to the first folded edge, and a gap is set between the second folded edge and the first folded edge;

[0004] The technical solution recorded in this proposal gathers the heat inside the bearing body onto the thermally conductive silicone sheet, and the heat on the thermally conductive silicone sheet is dissipated to the outside through the thermally conductive silicone sheet. It has a good heat dissipation effect and avoids the heat inside the bearing body from being unable to dissipate quickly, which causes changes in its material structure and increases the service life of the bearing. However, this solution does not have an active heat dissipation function when in use, resulting in low heat dissipation efficiency, which affects user use.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a dust-proof sealed bearing is provided to achieve a purpose with greater practical value. Utility Model Content

[0010] Furthermore, a sealing ring is installed on the end surface of the dustproof plate close to the inner sleeve, and sealing grooves are provided at the top and bottom ends of the inner sleeve, and the outer side of the sealing ring is slidably connected to the inner side of the sealing groove.

[0011] The beneficial effect of adopting the above further solution is that the connection sealing performance between the dustproof plate and the inner sleeve is improved through the sliding connection between the outer side of the sealing ring and the inner side of the sealing groove.

[0016] Furthermore, a gap is provided between the heat dissipation blades and the heat dissipation fins.

[0017] The beneficial effect of adopting the above further solution is that, by providing a gap between the heat dissipation blades and the heat dissipation fins, scratches between the heat dissipation blades and the heat dissipation fins are prevented.

[0018] Furthermore, the inner top end of the extension sleeve is inclined.
