How to improve the torque of worm gear and worm in slewing drive

In the process of designing slewing drives, U-TRSM design engineers often come across standardized slewing drives with the same size and space constraints that do not meet the performance parameters of the customer’s application. So in this situation, how to improve the torque and other parameters of the worm gear and worm in slewing drive is something we often need to consider. Here are a few points summarized by the U-TRSM design engineers, which are shared for your reference:

1. Increase the tooth ratio by increasing the tooth ratio between the worm gear and worm, such as double-headed or even multi-headed worm.

2. Optimize the design of the worm gear and worm, choose materials with better mechanical properties, optimize the structural design of the worm gear and worm, and increase its load carrying capacity and torque, such as changing the diameter, modulus, pressure angle, and other parameters of the worm gear.

3. Improving the machining accuracy can greatly reduce friction and wear, improve operating efficiency and service life, and thus increase torque.

4. Using the suitable lubricant can greatly reduce friction and wear, improve operating efficiency and service life, and thus increase torque.

5. Adjusting the preload force can eliminate the internal clearance and deformation of the worm gear and worm, improve the precision and stability, and thus increase the torque.

6. Regular inspection and maintenance to keep the slewing drive in good working condition.
