Conveyor Belt Conveyor Idler Analysis
An influencing factor dysfunctional roller
(1) roller manufacturing quality. Roller manufacturing problems mainly in the stiffness of the bearing seat belt is not enough, it is difficult to ensure accuracy of the idler
assembly, thereby constraining the roller operation flexibility.
(2) use of sealed lubrication and maintenance. Since the work environment is more severe Belt conveyor , generally site dust are large, bearing the seal forms flexibility for
running a great impact idlers, if seal is not good, it is easy to enter the dirt caused by roller bearings rotation is not flexible;
Also, if using the general bearing grease calcium base grease dries easily change color, you can not play a very good lubrication.
Idler running flexible approach
(A) in the manufacturing process of idlers guarantee the accuracy requirements, such as stamping bearing bore precision to achieve three, dimensional tolerances of the pipe
ends, concentricity and ovality must comply with GB, can not exceed the difference .
(2) sealed lubrication, in addition to manufacturing quality assurance, but to go with the better lubricating materials, such as using lithium grease, you can improve the
lubrication conditions, which prolong the service life of the roller is very necessary.
(3) using the radial ball bearing bearings, labyrinth seal plastic seal ring structure, both to ensure that the work roller reasonable force, and dust effects, resistance, and
easy assembly and disassembly, easy to maintain, effectively reduce the operating costs of the conveyor.
The main reason is caused by skidding traction rollers reduce friction, overloaded or belt is jammed.
(1) roller damage, debris winding, burying materials and other reasons will not turn a lot of rollers, conveyor belts or fittings damaged by increased resistance to idlers,
conveyor serious deviation, such as excessive cargo were so excessive resistance caused by belt conveyor design belt slipping.
(2) belt use for some time due to plastic deformation and elongation, resulting in insufficient belt tension, friction and traction while reducing slippage.
(3) the conveyor belt and the drive roller contact surface immersed in mud, dust, friction coefficient declined sharply, thereby belt slippage.
Tape slippage prevention and treatment
(A) to strengthen the operation of conveyor management, control the amount of material to prohibit overloading operation. In addition, the normal use of slip protection device,
when the conveyor belt to slip through the sensor signals, automatic shutdown, ease of maintenance treatment.
(2) on a regular or timely adjustment of belt tension. Car-tensioning device configuration or vertical belt tensioning device, belt slippage may add weight to resolve. But
should not add too much so as not to be subjected to unnecessary excessive belt tension and reduce its useful life; the
Spiral conveyor tensioning device configuration, when the belt slip adjustable tensioning stroke to increase tension; For those open layout of the conveyor, encounter rain,
snow, weather easily slip, the best Configuring hydraulic tensioner. Hydraulic tensioning device has an automatic increase in tension
Force compensation function, but also has broken with automatic shutdown feature.
(3) measures taken to prevent water spray, adding the non-face with a sweeper, and enhance the operator's responsibility, timely removal of mud on the roller, material and other
