How to improve the performance of idlers

Idler roller conveyors as a key component in the material transport 90 degree conveyor belt to withstand the resistance of more than 70% , as the utilization of large , large frequency of

replacement parts , in the selection, use , and maintenance are required in consider some aspects to improve the performance of idlers . Next

Side effects , I will introduce the main reason for the use of performance roller what .
First, the sealing effect is not good :
Sealing roller is used within the axial non-contact labyrinth seal , which is characterized by the inner and outer seal member is formed between the gap to achieve a small

tortuous sealing against dust is better, but the waterproof effect is poor, and mine vertical conveyor production conditions are dusty , and dust with water ,

So used roller seal must be dust-proof , waterproof effect. If the water will corrode the inner roller bearings, into the dust will damage the bearings , and ultimately affect

the service life of the roller .
Second , roller shaft concentricity difference:
Drawing roller shaft axis , which is characterized by a surface roughness and dimensional accuracy can be achieved without processing requirements of the drawings , with up
Convenient, saving labor . However, due to the optical axis of the production drawing tire tool wear due to factors such as dimensional accuracy is unstable, often have exceeded

the phenomenon , coupled with the transport process could easily lead to bend , so that the roller shaft concentricity deviation , roller shaft two side installation of the

bearing clearance can not be guaranteed ,

Thereby rotating roller resistance increases , affecting the life of the roller .
Third , bearing concentricity difference:
Roller bearing is used for stamping , and tube skin with the Department without processing , bearing sleeve welded directly on the skin . Stamping bearing skin is not round or

barrel at the end with the inequalities are easy to cause skin after welding ends of the cylinder bearing different axes , resulting in reduced bearing clearance , rotation

Resistance increases, the rotation is not flexible.
Idlers we all understand the importance of , and that the choice for idlers need to seriously consider seriously. The above three points that need to refer to when selecting

roller aspects , but also in the use and maintenance of rollers that need focused attention on three points .
