1, bearing installation
Bearing installation, removal methods, should be based on the nature of the bearing structure, size, and bearing components with. Therefore, adequate research in the design and installation of the assembly department. To be installed in accordance with the standard. The task of this project follows the usual standards
(1) of the bearing inner ring and the shaft is a tight fit, the outer ring and the housing as a more loose fit, available presses the bearing press-fitted in the bearing on the shaft is then loaded into the housing together with the bearing together, when press-fitted in the The end surface of the bearing pad assembly sleeve of a soft metallic material (copper or soft steel). The assembly casing diameter should be slightly larger than the journal diameter, outer diameter should be less than the diameter of the bearing inner diameter wall, in order to avoid pressure in the cage. A large number of installed bearings plus a handle on the sleeve.
(2) of the bearing inner ring and the shaft, the outer ring and housing bore is a tight fit, the end face of the assembly casing should be made simultaneously pressing the bearing end face of the inner and outer rings of the ring, or a disc and assembly sleeve, so that The pressure at the same time spread to the inner and outer rings, the bearings are pressed into the shaft and housing. This installation method is particularly suitable for the installation of the self-aligning radial spherical bearing.
(3) of the bearing outer ring and the housing bore for the tight fit, the inner ring and the shaft as compared to a loose fit, the bearing is pressed into the housing, this time assembled the outside diameter of the sleeve should be slightly less than the diameter of the housing bore.
(4) heating installation, hot charging bearings or bearing rings separable uniformly heated to 80 ~ 100 ℃ (should not exceed 100 ° C) into the fuel tank or dedicated heater.
2, after the installation of the bearing, requires careful adjustment, alignment may lead to bearing suffered another load, friction and vibration. This may accelerate fatigue and reduce life, and may cause damage to the period of use of other machine parts. In addition, the vibration and friction may greatly increase the risk of premature failure.
3, in the course of the operation, the bearing requirements correct re-lubrication, perfect performance. Bearing lubrication, divided into grease and oil lubrication. In order to make the bearing play function, first, to select the appropriate conditions of use, the purpose of the lubrication method. If only to consider lubrication, oil lubrication lubrication dominant. But the grease around the bearing structure can be simplified specialty.
4, when the bearing will reach its end-use period, it should be replaced. Although bearings can no longer be used, but the right to remove the original bearing the timely replacement of new bearings, can play a good role in promoting the new bearing life extension. First, removed appropriate use of the tools that will help to prevent damage to the other machine components, second, does not properly remove the technology might be the operator hazards.
5, in the course of often the bearing running external conditions monitoring, temperature monitoring, vibration and noise measurement. Factory production plan can be achieved, improving productivity and efficiency.
