With the selection principle of rolling bearings

The selection of rolling bearing with should be used according to the specific conditions ( Mainly load case) And its size to determine, see below illustrates in detail. Condition: bearing ring relative to the status of the load with the selection of principles: 1, the load swing in the direction to rotate or ring, choose the interference fit or transition fit, the load of the fixed ring 2, select clearance fit 3, when swimming with integral type bearing as the support, should be relative to the direction of the load for a fixed ring as swimming ring, choose the clearance fit or transition fit conditions: load the selection of type and size match principle: impact load or overloading load, choose cooperate more closely. The load, the greater the fit interference will condition: the greater the bearing size with the choice of principle: with the increase of the bearing size, choose the interference fit of the greater the amount of interference also; Gap, the greater the conditions of clearance fit, the bearing clearance with the choice of principle: USES the interference fit can lead to the decrease of the bearing clearance. Should check clearance whether meet the requirements of the bearings after installation, so that the correct choice to cooperate and bearing clearance condition: cooperate with the selection of other principle: the material of the shaft and bearing seat, strength and thermal conductive performance, external and heat in the bearing and its way of thermal conductivity, bearing installation and adjustment performance, etc. , shall be considered
