Flexible Gear Couplings

High performance and easy in installation manufactured using fully automatic hobbing machine.

Roller Chain Couplings

Roller Chain Flexible Couplings are compact, long lasting flexible couplings, capable of transmitting relatively high torques with minimum of space consumption

Torque Limiter

Nu-Teck torque limiter is a protective device that limits torque transmitted in a drive system by slipping when torque demand exceeds a preset value as a result of shock loads, over loads, or machine jams.

Sprockets

Nu-Teck Sprocket Wheels are manufactured from quality materials. Teeth are hob-cut for correct tooth form, tooth thickness and profile.

Half Flexible Gear Couplings

Under the misalignment condition of two shafts of the equipment, the teeth contact in case of straight cut hub will be as minimum as shown in the figure no. 1.

Under heavy loads the ends of the hub teeth will get damaged resulting in the excessive play between hub & sleeve. This leads to a reduction in the life of the coupling.

NU-TECK Triple Crowned Teeth

The triple crowned teeth hub is manufactured on a fully automatic hobbing machine with a built-in crowing attachment which is controlled by hydraulic & electronic systems. Under the misalignment condition of two shafts on the equipment, due to the curvature on teeth flank the contact area is much more. This means that there is an increase in the life of the coupling.

Misalignment Details

In case of straight tooth gear coupling the maximum allowable angular misalignment (μ) is .1/2 deg. and in case of Nu Teck Triple Crowned tooth Gear Coupling the misalignment is 1.1/2 deg.
