The function of bearing, function and use bearing plays a simple support.
If the driving part,
Such as shaft)
Cooperate with hole directly, the transmission resistance will be very big, after wearing is not easy to change.
Bearing through the support parts of rolling contact between driving part, so the sliding resistance is small, low consumption, start easy.
Bearing the main function is to support the mechanical rotator, reduce the coefficient of friction in the process of movement, ensure the rotation accuracy.
Understandably, it is used for a fixed axis, it can only rotate and its axial and radial motion control.
If there is no bearing shaft, it can't work at all.
Because can move in any direction of axis, and work only need axis rotation.
Bearings are widely used in automobile, rear wheel, transmission, and electronic components.
Electric: general motors, household electrical appliances.
Instruments, internal combustion engines, construction machinery, railway vehicle, loading and unloading machinery, all kinds of industrial machinery.
Machine tool spindle, agricultural machinery, high frequency motor, gas turbine, centrifugal separator, the car front wheel, differential pinion shaft.
Oil pump, roots blower, air compressor, all kinds of transmission, fuel injection pump, printing machinery, motors, generators, internal combustion engines, gas turbines, machine tool spindle, gear reducer, loading and unloading machinery, all kinds of industrial machinery, etc.
Almost as long as it in rotation, it USES the bearing.
A: 970. 801 million kind of high temperature resistant bearing is widely used in detail next up: the present situation of the bearing development in our country
