How toChoose Roller Crusher Bearing Correctly
Bearing is one of the most essential parts of roller crusher , if the roller crusher bearing choice is bad, will speed up the equipment to a great extent of wear and tear, thus accelerate the bearing replacement cycle, increase the equipment failure rate and the cost of production.What are the precautions for selection of roll crusher?Below is the luoyang dahua gives some Suggestions.
1. The size of the bearing size when choosing bearing must first determine the size, choose according to the size of the shaft bearing, large shaft roller bearing is generally selected, smaller axis choose ball bearings.
2, The bearing capacity of roll crusher of center line and the center line of the bearing pedestal is different, and the Angle of the differences, or bearing spacing is bigger and less rigidity of shaft, and then you can choose to have good regulatory roller bearings, as well as the outside of the ball bearing, the bearing under the condition of the tilted slightly, can maintain the normal work.
3, The speed of the bearing for roll crusher has its limited range , bearing itself has his own limit speed.If the bearing more than its speed will appear bearing temperature, lubricant dry, serious still can cause jammed condition of bearing.
4. Be sure to know the load of bearing. If is large load, select roller bearing, small load select carbon steel made bearing.
5.Bearing stress direction. Choose deep groove ball bearing, cylindric bearing, or needle bearing when the bearing is forced radial load. If force in small axial load, choose thrust ball bearing; in large axial load, choose thrust roller bearing. If the bearing is forced combined load in radial and axial direction, mostly choose angular contact ball bearing or tapered roller bearing.
