Torque arm - gear reducer 40

Torque arm – size 40 gear unit

The torque arm for a size 40 gear unit is a simple but key mounting element that allows a gearbox with a solid shaft to be mounted safely directly on the shaft of the driven machine, without the need for couplings or additional bearings. This makes installation faster, cheaper and takes up less space in the structure.

The main task of the torque arm is to take up the reaction torque generated during gear unit operation and transfer it to a fixed point of the structure - a frame, foundation or bracket - so that the gearbox housing does not rotate with the output shaft. In practice, this means lower dynamic loads transmitted to the machine shaft, longer bearing life and reduced vibration and noise throughout the drive system.

• Shorter installation time – the gear unit sits directly on the shaft, without a coupling
• Protects the driven shaft bearings from excessive radial loads
• Stable mounting that prevents the gear unit housing from rotating during operation
• Compatible with size 40 gearboxes, popular in conveyor, mixer and feeder drives
• Easy position adjustment thanks to connecting elements allowing a small correction of the setting
• Sturdy construction resistant to shock loads and continuous duty

The arm is made of durable materials, dimensionally matched to the size 40 gear unit housing, which ensures a secure, rigid connection without play. The fastening elements (bolts, bushings, pins) are usually included in the set, which speeds up implementation and removes the need to source additional components from other suppliers.

This is a solution for users who value simple installation and want to extend the trouble-free operation of the drive without the additional cost of couplings or auxiliary bearings.
