Description

Technical Field

[0001] The utility model relates to the technical field of sliding bearings, in particular to a sliding bearing which is convenient for adding lubricating oil. Background Art

[0002] At present, sliding bearings are bearings that work under sliding friction. Sliding bearings work smoothly, reliably and without noise. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil without direct contact, which can also greatly reduce friction loss and surface wear. The oil film also has a certain vibration absorption ability.

[0003] According to a Chinese patent with the publication number "CN211599301U", a sliding bearing is disclosed, including a base and a bearing, wherein fixing holes are opened on the left and right sides of the upper surface of the base, a lower bearing seat is fixedly connected to the middle of the upper surface of the base, a first connecting plate is fixedly connected to the upper part of the left and right ends of the lower bearing seat, a first guide rail is opened at the front and rear ends of the middle of the upper surface of the lower bearing seat, an upper bearing seat is arranged at the upper end of the lower bearing seat, a second connecting plate is fixedly connected to the lower part of the left and right ends of the upper bearing seat, the second connecting plate corresponds to the first connecting plate, a second guide rail is opened at the front and rear ends of the middle of the bottom of the upper bearing seat, and an oil guide hole is opened in the middle of the surface of the upper bearing seat. This type of sliding bearing improves the stability of the upper bearing seat during installation through the groove and the clamping plate, facilitates the assembly of the upper bearing seat through the fixing screw, the fixing nut, the first connecting plate and the second connecting plate, and facilitates the addition of lubricating oil through the oil filling hole and the oil guide hole. When in use, lubricating oil is added from the oil filling port so that the lubricating oil enters the interior of the bearing body from the oil pipe, which is very inconvenient. Frequent disassembly of the oil seal screw poses the risk of thread slippage, which will cause the staff to spend a long time to open the oil seal screw. The bearing body is not fixed and there is a risk of sliding. Therefore, a sliding bearing that is easy to add lubricating oil is proposed to solve the above-mentioned problems.
