Introduction to self-lubricating bearings
Self-lubricating bearings are divided into composite self-lubricating bearings, solid-inlaid self-lubricating bearings, and bimetallic materials.
Self-lubricating bearings, self-lubricating bearings of special materials, according to different uses and working conditions, choose different self-lubricating bearings.
One of the major types of solid inlaid self-lubricating bearings (JDB) is a novel lubricating bearing that combines the characteristics of metal bearings and oil-free lubrication bearings. The metal matrix bears the load, and the specially formulated solid lubricating material plays the role of lubrication.
It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. It is especially suitable for heavy loads, low speeds, reciprocating or swinging situations where it is difficult to lubricate and form an oil film, and it is not afraid of water wash and other acid erosion. And scouring. Products have been widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, molds, lifting machinery, textile machinery, wind power generation, ships, steam turbines, water turbines, injection molding machines and equipment production lines. The wear resistance is twice that of ordinary bushings.
General-purpose steel base oil-free self-lubricating bearings
1 No oil lubrication or less oil lubrication, can be used without maintenance or less maintenance.
2 Good wear resistance, low friction coefficient and long service life.
3 It has an appropriate amount of elasticity and plasticity, which can distribute the stress on a wider contact surface and improve the bearing capacity of the bearing.
4 The static and dynamic friction coefficients are similar to ensure the working accuracy of the machine.
5 It can reduce the vibration of the machine, reduce noise, prevent pollution, and improve working conditions.
6 A transfer film can be formed during operation to protect the grinding shaft.
7 The hardness requirements for the grinding shaft are low, which reduces the processing difficulty of related parts.
8 Thin-walled structure, light weight, can reduce the mechanical volume.
9 The back of steel can be electroplated with a variety of metals, which can be used in corrosive media; it has been widely used in sliding parts of various machines.
