Gearboxes are widely used across many industries. However, numerous issues can arise during their installation. Below is a brief overview of the main problems encountered during installation and their solutions:
Problem of Shaft Breakage Due to Insufficient Load Capacity:
When selecting a model, users often mistakenly believe that meeting the required output torque is sufficient. This is not entirely accurate. First, the rated output torque of the matched motor multiplied by the reduction ratio should, in principle, be less than the rated output torque of a similar gearbox model provided in the product catalog. Second, the overload capacity of the drive motor and the actual maximum required working torque must also be considered. Theoretically, the rated output torque of the gearbox should be more than twice the user’s maximum required working torque. This guideline is particularly critical in certain applications, as it not only protects the internal gears of the gearbox but, more importantly, prevents the output shaft from being twisted off. The main reason is that if there are issues with equipment installation and the gearbox’s output shaft or its driven host machine becomes jammed, the drive motor’s overload capacity will continue to increase its output. This may cause the force on the gearbox’s output shaft to exceed twice its rated output torque, resulting in shaft breakage. Additionally, if the instantaneous torque borne by the output shaft during frequent acceleration and deceleration exceeds twice its rated output torque, it can ultimately lead to shaft failure.
Solutions:
Pay close attention to model selection when purchasing a gearbox. It is advisable to choose a model with slightly higher specifications than strictly required, rather than opting for a marginally adequate model due to lower cost or other reasons. Choosing an undersized model is more likely to lead to problems.
