Solution when the load torque exceeds the rated load of the reducer by S67D112M84-1.5-26.93

Reducer Selection adjustment

Replacing large-sized reducer: This is the most direct and effective method. Depending on the actual load torque, select a reducer model with higher load capacity, such as upgrade to a larger reducer such as the S77 to ensure that the reducer can withstand the required load.

Using multi-stage reducer: you can consider using multi-stage reducer in series to share the load. By reasonably configuring the transmission ratio of reducers at each level, the load bearing by each level of reducers is within its rated range, which can not only meet the load requirements but also improve the transmission efficiency to a certain extent.

Load optimization

Optimize process flow: Evaluate and optimize the entire production process flow to see if the actual torque the reducer can be reduced by adjusting the operating mode and reducing unnecessary loads. For example, optimize the speed and amount of material transportation to avoid excessive load shocks in a short period of time.

Balancing load: Check whether the load is unbalanced, such as adding auxiliary equipment or adjusting the load distribution, so that the load is evenly distributed to each transmission component, thereby reducing the local load pressure of the reducer. For some devices with multiple driving points, a load balancing device can be used to ensure load balancing of each driving point.

Power system adjustment

Increase the power of the drive motor: If the motor power is insufficient, it is one of the reasons why the load torque exceeds the rated load of the reducer, consider replacing a motor with more power. This can provide more power so that the reducer will not bear excessive load due to insufficient motor output torque during operation. However, it should be noted that the increase in motor power must be matched with the transmission capacity of the reducer to avoid the situation of 'large horse pulling small cars' and causing energy waste.

Adopt variable speed drive: install variable speed drive devices such as frequency converters to adapt to load changes by adjusting the running speed of the motor. When the load is large, the motor speed can be appropriately reduced to reduce the output torque and avoid overloading of the reducer; when the load is small, the motor speed can be increased and production efficiency can be improved. This method can flexibly adjust the motor output according to actual working conditions, so that the reducer can operate within a more reasonable working range.

Strengthen maintenance and monitoring

Regular maintenance: Strengthen the daily maintenance and maintenance of the reducer to ensure that it is in a good working condition. Regularly check the wear of key components such as gears, bearings, etc. of the reducer, and replace parts with severe wear in a timely manner to reduce the reduction in transmission efficiency and additional load caused by component wear. At the same time, keep the lubrication system of the reducer good, and regularly replace the lubricant oil to ensure that the quality and oil volume of the lubricant meet the requirements, so as to reduce friction resistance and improve transmission efficiency.

Real-time load monitoring: Install torque sensors and other monitoring equipment to monitor the load status of the reducer in real time. When the load torque is close to or exceeds the rated value, an alarm will be issued in time so that the operator can take corresponding measures, such as adjusting the production process, stopping the equipment operation, etc., to avoid the reducer operating under overload for a long time and extend its service life.
