Factors affecting the performance of thespiral conveyor idlers
As an important part of roller belt conveyor , belt conveyor transport materials when exposed to more than 70 % of the resistance. As usage large, large frequency conveyor replacement parts, we need to consider some aspects of the selection, use and maintenance to improve the performance of idlers . Here, on the Hai Yu sound mechanical introduce affect performance ZM Belt conveyoridlers major factor . ( A ) the sealing effect is not good: the internal use of the sealing roller is axially non -contact labyrinth seal , which is characterized by the inner , outer seal is formed between the gap to achieve a small zigzag sealed better dust , but the water is less effective , and production status of underground ZM Pharmaceutical metal detectoris dusty , and dust with water , so that the sealing rollers must have a good dustproof, waterproof effect. If the water will corrode roller bearings, into the dust will damage the bearings, the ultimate impact idlers life. ( 2 ) roller shaft concentricity difference: drawing roller shaft axis , which is characterized by its surface roughness and dimensional accuracy can be achieved without working drawings , easy to use them , saving labor . However, due to wear and tear due to mold and other factors caused the production of dimensional accuracy when drawing axis unstable , often have exceeded the phenomenon , coupled with the transport process could easily lead to bend , so that the roller shaft concentricity poor , two idler shaft bearing clearance side installation can not be guaranteed , so that the roller rotation resistance increases , the impact roller life. ( 3 ) bearing concentricity difference: roller bearing is used for stamping , leather tie at the cylinder without processing , bearing directly on the cylinder welded skin . When stamping bearing is not round or cylindrical end face inequality skin are easy to create with the Department after the tube leather welding different ends of the bearing shaft , resulting in reduced bearing clearance , rotational resistance increases, the rotation is not The importance of idlers we all understand , then for idlers need to carefully consider the choice of treatment . The above three aspects that need to refer idler selection , but also in the use and maintenance of rollers need to focus attention in the three points.
