Description

Technical Field

[0001] This utility model relates to the field of bearing end cap technology, specifically to an oil-proof bearing end cap assembly. Background Technology

[0002] A bearing cap is a component used to secure and protect a bearing, typically installed on the outside of the bearing. Its main functions include: fixing the bearing position to prevent movement or loosening during operation; protecting the bearing by preventing dust, impurities, and lubricating oil from leaking out, extending bearing life; and maintaining lubrication by helping to retain the lubricating oil or grease inside the bearing.

[0003] Existing bearings often vibrate during operation due to their installation location or structural issues. This vibration causes wear at the connection between the bearing and the bearing cap, affecting the stability of the connection and compromising the seal. Consequently, the bearing cap's ability to seal the bearing is compromised, leading to lubricant leakage. Therefore, these bearings have certain shortcomings.

[0004] In conclusion, it is necessary to invent an oil-proof bearing cap assembly. Utility Model Content

[0005] To address this issue, this utility model provides an oil-proof bearing cap assembly to solve the problem that some bearings often vibrate during operation due to issues with their installation location or structure. This vibration not only causes wear at the connection between the bearing and the bearing cap during rotation but also affects the stability of the connection, thus compromising the sealing performance of the bearing cap.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil-proof bearing cap assembly, including an outer cover, an inner cover installed at the front opening of the outer wall of the outer cover, and oil-proof components disposed close to the outer cover and the inner cover.

The outer wall of the inner cover 200 is connected to the inner wall of the mounting groove 110. The outer wall of the inner cover 200 is fixedly connected to the inner wall of the mounting groove 110 by bolts. By opening the mounting grooves 110 and bolts, the outer cover 100 and the inner cover 200 can be set up with separate structures, so that personnel can replace them in time when either of them is worn.

[0024] The outer cover 100 and inner cover 200 are equipped with oil leakage prevention components, including movable pressure rings 120. The movable pressure rings 120 are all located on the inner wall side of the outer cover 100 and on the outer side of the bearing outer wall. A first rubber sealing ring 130 is fixed to the inner wall side of each movable pressure ring 120. The first rubber sealing ring 130 is fixedly abutted against the outer surface of the bearing. The first rubber sealing ring 130 can be made of rubber and has a certain degree of elasticity. When it abuts against the outer wall of the bearing, even if the bearing vibrates, the sealing performance of the first rubber sealing ring 130 will not be affected. A first clamping spring 121 is fixed to the outer wall of the movable pressure ring 120 near the outer cover 100. Multiple first clamping springs 121 are evenly arranged in a ring array, with the first clamping springs 121 located away from the movable pressure ring 120. One end of each of the 20 is fixedly connected to the inner wall side of the outer cover 100. The first clamping spring 121 will make the movable pressure ring 120 and the first rubber sealing ring 130 reach the outer ring of the bearing through elastic force. The movable pressure ring 120 is used to fix the first rubber sealing ring 130. The movable pressure ring 120 can be made of plastic material and can deform to a certain extent. The outer wall side of the outer cover 100 is provided with threaded holes for connection. Multiple threaded holes are evenly arranged in a ring array. The inner wall of each threaded hole is threaded with a clamping bolt 140 for clamping. The insertion end of the clamping bolt 140 passes through the threaded hole and abuts against the outer wall of the movable pressure ring 120. Personnel can rotate the clamping bolt 140 to clamp the movable pressure ring 120 and the first rubber sealing ring 130 against the outer wall of the bearing to ensure the sealing of the connection with the outer wall of the bearing.

[0025] The oil leakage prevention component also includes an inner pressure ring 210, which is fixed to the outer wall side of the inner cover 200 and corresponds to the position of the through hole in the outer cover 100. The inner pressure ring 210 can be snapped onto the inner wall of the bearing. Each inner wall of the inner pressure ring 210 is provided with a second rubber sealing ring 220, which can improve the sealing performance after the inner pressure ring 210 is connected to the inner wall side of the bearing. A second clamping spring 222 is fixed to the end of the second rubber sealing ring 220 near the inner pressure ring 210. Each adjacent second clamping spring 222 is fixed with a second pressing spring 222. There is a rubber buffer pad 221. The ends of the rubber buffer pad 221 and the second clamping spring 222 away from the second rubber sealing ring 220 are both fixed to the inner wall side of the inner pressure ring 210. The second clamping spring 222 can improve the sealing performance of the connection between the second rubber sealing ring 220 and the inner wall side of the bearing through elastic force. The rubber buffer pad 221 can buffer and absorb the vibration generated by the inner wall of the bearing during operation, so as to reduce the transmission of vibration to the inner pressure ring 210. At the same time, it can also improve the sealing performance after the second rubber sealing ring 220 abuts against the inner wall of the bearing.
