The application of sliding bearings is very extensive, such as textile machines, printing machines, automobiles, tobacco machinery, micro-motors, motorcycles and agricultural and forestry machinery, etc., sliding bearings have their own characteristics and advantages. So, why are sliding bearings widely used? Let's take a brief look!
1. Sliding bearings can reduce vibration, noise, pollution, and improve working conditions. It has an appropriate amount of elastoplasticity, which can distribute the stress on a wider contact surface and improve the bearing capacity of the bearing. Sliding bearings have good wear resistance, low friction coefficient and long service life.
2. The static and dynamic friction coefficients are similar, which can eliminate crawling at low speeds, thereby ensuring the working accuracy of the machine. No or less oil lubrication, suitable for places where it is impossible or difficult to refuel. It can be used without or with little maintenance.
3. The sliding bearing can form a transfer film during operation, which can protect the grinding shaft without the phenomenon of shaft biting. Sliding bearings have low hardness requirements for grinding shafts, and shafts that have not been quenched and tempered can be used, thereby reducing the difficulty of processing related parts.
4, thin-walled structure, light weight, can reduce mechanical volume. The back of steel can be electroplated with a variety of metals and can be used in corrosive media. Sliding bearings have been widely used in sliding parts of various machines.
