Background

The part for supporting the relative rotating shaft is a bearing, the bearing is an important part in mechanical equipment, and the bearing has the main function of supporting a mechanical rotating body, reducing the friction coefficient in the movement process of the mechanical rotating body and ensuring the rotation precision of the mechanical rotating body.

The bearing has the following functions in mechanical equipment:

1. the support, i.e. for carrying the shaft, is essentially capable of taking up radial loads.

2. Lubrication, the lubrication of the rolling bearing can reduce the internal friction and abrasion of the bearing and prevent burning and sticking; the service life of the bearing is prolonged; the lubricating method of the bearing comprises grease lubrication and oil lubrication. The amount of the lubricant is particularly required to be used during lubrication, and no matter oil lubrication or grease lubrication is adopted, the service life of the bearing is influenced by insufficient lubrication when the amount is too small, and the rotating speed is influenced by large resistance generated when the amount is too large.

3. The sealing of the bearing can be divided into self-contained sealing and external sealing. The bearing with the seal is a device which is manufactured by the bearing with the sealing performance. Such as bearing with dust cap, sealing ring, etc. The sealing occupies small space and is convenient to mount and dismount; the bearing outer seal is a seal device manufactured to have various performances when an internal member such as an end cap is mounted. The external seal of the bearing is divided into a non-contact seal and a contact seal. The non-contact type sealing is suitable for high-speed and high-temperature occasions and has different structural forms such as a gap type, a labyrinth type and a gasket type. The contact type sealing is suitable for working conditions of medium and low speed, and is commonly used in structural forms of felt sealing, leather cup sealing and the like.
