Description

One end flat belt eccentric sleeve outer spherical ball bearing Technical Field The utility model belongs to the technical field of ball bearings, and particularly relates to an outer spherical ball bearing with an eccentric sleeve at one end. Background The eccentric sleeve outer spherical ball bearing is a bearing with a special structure, combines the aligning characteristic of the outer spherical ball bearing with the unique function of the eccentric sleeve, and is widely applied to various scenes in industrial production and operation of various mechanical equipment, and the special structure can adapt to complex working conditions such as the neutral difference of the axis of the shaft and the seat hole. The prior ball bearing has the following defects: 1. After long-term operation, the bearing is easy to wear, when the wear reaches a certain degree, serious vibration can be generated, but the existing bearing generally lacks an effective wear early warning mechanism, so that workers cannot easily detect the abnormal state of the bearing in time, and problems are often found when the bearing is worn seriously to cause equipment to be in a fault and stop, so that the normal operation of the equipment is influenced, and the production is interrupted due to sudden damage of the equipment, so that great economic loss is brought; 2. In the aspect of lubrication maintenance of bearings, the traditional mode is mostly dependent on manual periodic addition of lubricating oil, and a convenient and visual lubrication monitoring means is lacked. Operators are difficult to know the residual quantity of the lubricating oil in the bearings in real time, and the bearing can run in an oil shortage state due to the fact that the lubricating oil is not supplemented in time, so that abrasion is increased, the service life of the bearings is shortened, and the stability and reliability of the whole equipment are further affected.
