This respect, should consider to choose high temperature bearing

Teach you high temperature rolling bearings which we should give full consideration to the choice of several main aspects in order to select suitable high temperature bearing designed, stopped the mechanical application of high temperature bearing conditions, performance requirements, high temperature surrounding the bearing specification, and the comprehensive analysis of the marketability and economy. Owing to generally determine the diameter of axle first, then choose high temperature bearing, so we must first of all, based on the high temperature bearing inside diameter, considering the conditions such as high bearing installation space and configuration conditions, a preliminary determine the type of high temperature bearing; Secondly, high temperature bearing is by comparing the size of the high temperature bearing life needed for the 'mechanical' and 'high temperature bearing load calculated by the high temperature bearing life', the level of precision, internal clearance are attached to the frame, the high temperature of bearing lubricating oil internal structure and determine the basic requirements. Choice of general steps as follows: as shown in figure 1, the really high temperature bearing type and configuration. （ Reference elements include: equipment temperature bearing space; High temperature bearing load size, direction and nature; Speed; Rotation accuracy; Noise and friction torque; Rigid; As described in the inner ring and outer ring of relative tilt; And removing device; High temperature bearing configuration; Market and economic) 。 2, high temperature influence bearing size is. （ High temperature lead to the service life of the bearing of machinery can request; Equivalent dynamic load. Equivalent static load. Speed; The main work size of high temperature and bearing; Basic dynamic load rating; At the rated static load; Allow the axial movement of the load) 。 3, precision grade really. （ Rotation accuracy; Noise and friction torque; Speed; High temperature bearing accuracy) 。 4, cooperate with the internal work clearance. （ The size of the load and the nature; Temperature in the operation of respectively; Shaft and housing information, size and accuracy; Cooperate; The difference in temperature of inner ring and outer ring; Speed; Pre-tightening force; High temperature impact bearing calculation accuracy; High temperature lead to bearing internal clearance) 。 5. Stick to the frame data and types. （ Speed; Noise) 。 Figure 6. A special case. ( Medium conditions, such as temperature, water, vacuum, medicine, dust, gas, magnetic field, etc. ; Special data; Special heat treatment; Special surface treatment; Lubricant) 。 7, smooth, smooth agent and seal installation. （ The use of temperature; Speed; A smooth way; Smooth agent; Seal installation; High temperature bearing speed limit; Smooth life grease) 。 8, device and the method and mechanism is removed for working size. 9, high temperature bearing and its surrounding the final specification for sure. In order to obtain the final high temperature bearing performance, in order to satisfy the request. A: choosing teaching quality under the high temperature impact bearing to bearing a: no
