Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bearing lubrication technology and relates to a bearing oil circulation lubrication device. Background Technology
[0002] Existing bearing roller lubrication technology cannot guarantee lubrication stability during the bearing lubrication process. Insufficient lubrication leads to increased internal friction in the bearing, thereby accelerating wear and shortening its service life. Uneven lubrication can cause localized overheating, resulting in material degradation and even sintering. The root causes of these shortcomings lie in improper lubrication system design, mismatched lubricant selection, harsh operating environments, or untimely maintenance. Conventional solutions include using high-quality lubricants, improving lubrication system design, regularly inspecting and replacing lubricants, and adopting automated lubrication systems. However, these methods also have drawbacks. While using high-quality lubricants can improve lubrication performance, it is costly; improving lubrication system design may require significant initial investment and structural modifications; and while regularly inspecting and replacing lubricants can ensure lubrication quality, it requires substantial manpower and time. Therefore, there is an urgent need for a bearing oil circulation lubrication device to solve these problems. Utility Model Content

The bearing body to be lubricated is horizontally placed into the bearing groove of the main positioning seat, ensuring that the bearing body is aligned with the axis of the oil guide cavity. The front positioning shell and the rear positioning shell are respectively fixed to the main positioning seat with bolts. The front and rear sides of the bearing housing are designed to ensure that the convex annular structure of the sealing liner fits tightly against the edge of the bearing groove, forming a radial seal. Then, the external lubricating oil supply pipe is sealed to the outside of the oil inlet. After the oil supply system is started, the lubricating oil is evenly distributed to the bearing raceway through the oil guide cavity. The rubber sealing liner and the sealing inner liner work together to prevent leakage. During the lubrication process, the flow rate at the oil outlet needs to be monitored. When the oil flows out continuously and stably, the oil supply is stopped. When disassembling, first disconnect the oil pipe, then remove the front sealing plate, the rear sealing plate, and the positioning shell bolts in sequence, and finally remove the bearing body to complete the lubrication of the bearing raceway.

At the same time, the rear sealing insert is tightly fitted to the rear side of the front sealing plate to enhance the sealing performance. During the lubrication operation, lubricating oil is injected from the oil inlet. The oil is evenly diffused to the bearing raceway through the oil guide cavity. The embedded positioning ring ensures that the oil passage is unobstructed. The sealing outer liner and the sealing inner liner work together to prevent oil leakage. Excess oil flows back to the circulation system from the oil outlet.
[0013] In practical use, the external lubricating oil supply pipe is sealed to the outside of the oil inlet. After the oil supply system is started, the lubricating oil is evenly distributed to the bearing raceway through the oil guide cavity. The rubber sealing outer liner and sealing inner liner work together to prevent leakage. During the lubrication process, the flow rate at the oil outlet needs to be monitored. When the oil flows out continuously and stably, the oil supply is stopped.
