Roller conveyor belt feeding heavy start-up requirements

    When the roller conveyor is stopped for any reason with the material , and then start belong reload starts. Requirements for Telescopic belt conveyor drive can be started with a

heavy material . Drum machine starts with the material to be reloaded , the motor output torque , that is, to overcome the belt support rollers and wheels each of the following

The static friction between the shaft caused by the resistance torque , but also the material in the drum to overcome the downward force caused by the drag torque . The material

in the drum of the tension caused by the downward drag torque is constant. The static friction is more than the dynamic friction large , which makes for overcoming the static

friction

The initial starting torque , compared with the normal operation of the dynamic friction moment of resistance caused by a large number. So the drive must have a low speed and

high starting torque function. Actually boot process , since the drum elasticity , each roller is rotated in order by industrial belt conveyor successively , not both

Rotation. Even if the wheel turning up , because the speed is low , between the roller and the roller shaft poor lubrication , will be very astringent , the dynamic friction is

unstable, and therefore the starting torque low speed a certain fluctuations. But in the startup process, take some time to

So that all wheels are turning up the torque began to decline. Only up to a certain speed , improved lubrication , the torque fluctuations will be reduced. Therefore, such a

large low-speed starting torque , is the need to maintain a certain amount of time , generally at least a few seconds. And the roller length and the start

The minimum speed , and the belt elasticity and so on. And start the low speed, torque and speed fluctuations will be relatively large .
