Something About Worm Gear Reducer

A worm gear reducer is a right angle gear solution that allows the maximum speed reduction in the smallest package.

It was used in low to moderate horsepower applications. They offer low initial cost, high ratios, and high output torque in a small package. They have a much higher tolerance for shock loading then helical gear reducers. Helical reducers are used in higher horsepower applications where long-term operational efficiency is more important than initial cost.

Some of the most common causes for premature failure of a worm gear reducer include improper selection for the application, changing the motor horsepower or speed, incorrect alignment of couplings, improper or insufficient lubrication, and lack of regular maintenance.
