Broken shaft gearhead
Belt conveyor gear reducer occur at off-axis high-speed shaft. The most common is the use of a reducer of the first stage bevel gear shaft perpendicular to the high speed shaft.
Occurs off-axis for two main reasons.
Reducer speed shaft design strength is not enough
This situation generally occurs at the shoulder of the shaft, because here there are fillet, prone to fatigue damage, such as rounded corners make the gear is too small in a
short period of time broken shaft. After the broken shaft fracture usually flush. This happens should be replaced or modified gear reducer design. drag chain conveyor
Speed shaft misalignment
Motor shaft and reducer speed shaft misalignment causes the input shaft when increased radial load, increase the bending axis, long-term operation will occur off-axis
phenomenon. In the installation and maintenance of its location should be carefully adjusted to ensure that two concentric shafts. In most cases do not occur off the motor shaft
Axis, this is because the motor shaft 45 steel materials are generally, relatively coarse motor shaft, stress concentration is better, so that the motor axis is usually not

Dual motor drive in case of off-axis
Dual motor drive is on the same drive gear equipped with two rollers and two motors. High-speed shaft of the gear unit design or selection of smaller margin more likely to occur
when the phenomenon of broken shaft. Belt conveyor drive past without using fluid couplings are more prone to this type of situation, because the two Taipower
Machine startup and runtime speed synchronization and the force balance is difficult to guarantee. Now, most have adopted a fluid coupling less off-axis phenomenon occurs, but
should pay attention to the amount of fuel coupling can not be too much so that it has a role and improve the torque limiting coupling life.
Shorter life of the belt
Life of the belt and the belt with the belt usage condition related to quality. Conveyor belt cleaner running should ensure a reliable easy to use, there should be no material
return belt. If the content can not guarantee the return trip will occur with the return of the material on the belt drive roller or belt into
Idler pulleys, belts will be put bad material, and may damage the drum surface layer of vulcanized rubber. Will appear on the belt break, reducing the life of the belt. Belt
manufacturing quality is more concerned about a user content. After the selection of a model should also assess the quality of its manufacturing.
National accreditation bodies have a special quality can be tested. Appearance can be performed on routine checks to see whether there is cracking, aging, manufacturing storage
time is too long after. One of the above situation should purchase. In the initial discovery of cracks tend to use belt
Between relatively short on damage.
