Analysis and Prevention of Common Troubles in Overhead Hoist Trolley Crane Reducer

Analysis and Prevention of Common Troubles in Overhead Hoist Trolley Crane Reducer：

1 failure analysis

The reducer is an important transmission part of the Overhead Hoist Trolley Crane. The torque is transmitted through the gear meshing, and the high speed operation of the motor is transferred to the required speed. The gear will be broken during the transmission torque. And tooth surface wear and other mechanical failure, resulting in gear failure were as follows:

A. Short time overload or by the impact of the load, repeated bending caused by repeated fatigue break;

B. Tooth surface is not smooth, there are raised the stress concentration, or lubricant is not clean;

C. Due to excessive temperature caused by lubrication failure;

D. Due to hard particles into the friction surface caused by wear and tear.

2 Precautions

A. Overhead Hoist Trolley Crane can not be used to start, start, brake to be slow, smooth, non-specific circumstances prohibit the sudden anti-car;

B. Replace the lubricant in a timely manner, and clean the shell, and to select the appropriate type of lubricant;

C. Always check whether the oil is clean; find that lubrication is not clean and timely replacement.
