Belt conveyor idler is an important component of many kinds and large quantities. It accounts for a total cost of 35% of the belt conveyor idlers
Bear more than 70% of the resistance, so the quality of the roller is particularly important.
Role is to support the roller conveyor and material weight. Roller operation must be flexible and reliable. Reducing roller conveyor with friction, accounting for the total cost of the conveyor belt more than 25% of life plays a key role. Although the roller is a relatively small component in the belt conveyor, the structure is not complicated, but produce high-quality roller is not easy.
Analyzing roller quality standards were the following: roller radial runout; axial runout; roller flexibility.
Deep groove ball bearing inner and outer ring raceway were tested arc-shaped groove, the channel is slightly larger than the radius of the sphere radius. Mainly used to bear radial load, but also bear certain axial load. When the bearing radial clearance to increase, with angular contact ball bearings, can withstand large axial load, but also for high-speed rotation. Bearings and tilted relative to the housing bore axis 8 to 16, still work, but the impact of its service life. And should not be used in high speed thrust ball bearings in the case of such bearings can withstand pure axial load.
Deep groove ball bearings generally use steel stamping a two-part synthetic cage, but the size or speed bearing solid cage is used that cage with stamping cage, as guided by the ball, holding the high-speed deep groove ball bearings frame is usually guided by the inner or outer wall.
With the same size of other types of bearings, deep groove ball bearing friction coefficient is small, lower vibration and noise, extreme high speed, high precision, user selection of the preferred bearing type. However, these bearings the impact of intolerance, not suited to withstand heavy loads.
Deep groove ball bearing structure is simple, easy to use, is the largest production volume, most widely used range of a class of bearings. Widely used in automobiles, household appliances, machine tools, motors, pumps, agricultural machinery, textile machinery and many other areas. Its production accounts for over 70% of total output bearing, our country is the highest yield, the most common and least expensive type of bearings.
