The main reasons for the inflexible operation of the rollers and measures to solve the problem

Belt conveyor in a large number of rollers, is one of the important parts of the conveyor, its price is about 25% of the total price of the conveyor, roller maintenance and replacement costs are also an important part of the operating costs of the belt conveyor, roller operation of the entire conveyor running resistance, power consumption, the service life of the rollers and conveyor belts, maintenance workloads and transportation costs have a great impact.

1 Reasons for inflexible roller operation

Factors affecting the degree of flexibility of roller operation and its service life are mainly the following aspects.

(1) the manufacturing quality of the rollers. Mainly in the bearing seat stiffness is not enough to ensure the assembly accuracy of the rollers, thus restricting the flexibility of the roller operation.

(2) Seal lubrication and maintenance. As the working environment of the belt conveyor is relatively harsh, generally speaking, the use of the site of the dust is very large, the bearing housing sealing form of roller running flexibility has a great impact, if the sealing is not good, dirt is easy to enter the bearing caused by the roller rotation is not flexible; in addition, the bearing lubricating grease, if you use the general calcium-based lubricating grease is easy to discoloration and drying, can not play a very good role in lubrication.

2 roller running inflexible solution measures

(1) in the manufacturing process to ensure that the specified precision requirements, such as stamping bearing housing bore accuracy to reach level 3, the size tolerance, coaxiality and ellipticity of the two ends of the tube body must be in line with the national standard, can not exceed the difference. There should be strict quality inspection of the products to ensure that all the factory products are qualified.

(2) sealing lubrication, the equipment should be equipped with qualified lubrication materials, such as the use of lithium grease, which can improve the lubrication of the bearings, which is very necessary to extend the service life of the rollers.

(3) The bearing seat adopts centripetal ball bearing support, plastic sealing ring labyrinth sealing structure, so as to ensure that the rollers work with reasonable force, while the dustproof effect is good, low resistance, and easy to install and dismantle, easy to maintain, which can effectively reduce the operating costs of the conveyor.

Belt conveyor routine maintenance, analyze and solve some of the main problems affecting the normal operation of the belt conveyor, to ensure the good operation of the equipment, can effectively improve production efficiency. Welcome to leave a message to exchange the problems you encountered.
