Compact worm gear drives deliver improved performance

28 May 2013

Tsubaki Europe has launched a new range of Troi Drive and Worm Power Drive reducers which benefit from an improved oil seal design for reduced maintenance requirements.

The reducers are available in a range of sizes and offer a compact design which makes them suitable for most applications. The design follows Tsubaki’s '€co & Eco' philosophy which embraces economy and ecology to deliver products which offer high performance with reduced total life costs.

Starting with the compact base unit, a choice of input and output shaft types can be selected followed by the shaft and mounting style required by each situation. Both the Troi Drive and Worm Power Drive products employ a worm gear-to-wheel configuration which enables them to provide a very high reduction ratio, generally 1:10 to 1:60, with a self-locking ability; reduction ratios of 1:100 to 1:3600 are also available by selecting a double reduction drive.

Because the power is transmitted through a regular sliding contact, the use of a worm gear results in extremely low vibration and noise, even when dealing with high torque loads. 

The smaller, compact design of the Worm Power Drive range is capable of producing an output torque from 12Nm up to 5,700Nm. It is available with either solid or hollow output shafts with a range of mounting options, making it suitable for a variety of applications.

Improvements to the oil seal design on both the input and output shafts has doubled the life of the oil seals. Additionally, the environmental credentials have been improved by changing the paint process to electrostatic baking and by removing the use of paint thinners.

The larger, Troi Drive TD series reducer uses a drum shaped troidal worm gear, which provides premium performance and efficiency. Solutions are available in medium to large sizes (125-315), with both solid or hollow output shafts, and output torques from 1,100Nm up to 47,000Nm.
