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.
1 reducer high speed shaft design strength is not enough
This situation generally occurs in the shaft shoulder because here there 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.flexible conveyor
2 high-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, which is due to the motor shaft 45 steel materials are generally, relatively coarse motor shaft, stress concentration is better, so that the motor axis is usually not
3 pairs in case of broken motor drive shaft
Dual motor drive is a drive rollers in a unified reducer and two equipped with two motors. High-speed shaft of the gear unit design or selection margin is small compared prone
to the phenomenon of broken shaft. Belt conveyor drive past without using hydraulic devices such situations are more prone to coincidence, because the two TaipowerMetal detector for food
Machine startup and runtime speed synchronization and the force balance is difficult to guarantee. Now, most have been used off-axis hydraulic coincidence is less common
