Advantages of self-lubricating bearings
Self-lubricating bearings are divided into composite material self-lubricating bearings, solid-inlaid self-lubricating bearings, bimetal material self-lubricating bearings, and special materials self-lubricating bearings. According to different uses and working conditions, different self-lubricating bearings are selected, one of which is solid inlaid Self-lubricating bearing (JDB for short) is a novel smooth bearing that combines the characteristics of metal bearing and oil-free smooth bearing. The metal matrix receives the load, and the specially formulated solid smooth material plays a smooth role.
It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-smoothing ability. It is especially suitable for heavy loads, low speeds, reciprocating or swinging places that are difficult to smooth and form an oil film, and are not afraid of water washing and other acid erosion. And scouring. Products have been widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, molds, hoisting 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.
The advantages of self-lubricating bearings (oil-free bearings), most of the bearings used in various machinery industries are balls, needles and the like, but a small part of them has adopted self-lubricating bearings. It is believed that smooth bearings will become the dominant bearing in the near future. The following are the application characteristics and advantages of partial self-lubricating bearings: oil-free smooth bearing series, oil-free smooth or low-oil smooth, suitable for places where it is impossible to refuel or it is difficult to refuel, and can be used without or with little care.
Self-smoothing bearings Self-smoothing bearings have good wear resistance, low friction coefficient, long service life, and proper elasticity, which can spread stress on a wide contact surface and improve the bearing capacity of the bearing. The static and dynamic friction coefficients are similar, which can eliminate creeping at low speeds, so as to ensure the working accuracy of the machine. It can reduce vibration, noise, avoid pollution and improve working conditions.
During operation, it can form a transfer film, play a role in maintenance of the grinding shaft, without the phenomenon of shaft biting, the hardness of the grinding shaft is low, and the shaft without quenching and tempering treatment can be used, thereby reducing the processing difficulty of related parts , Thin-walled structure, light weight, can reduce the mechanical volume, the steel back can be electroplated with a variety of metals, which can be used in corrosive media; it has been widely used in the sliding parts of various machines.
