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 the reduction in life of coupling.

Nu-Teck Roller Chain Flexible Couplings are compact, all steel, long lasting flexible couplings, capable of transmitting relatively high torques with minimum space consumption. Consequently, they provide a most economical means of positive transmission of power from one shaft to another. The simple design and construction of these couplings make them extremely easy to install and disconnect, providing additional economy of operation.
The sprockets are identical in construction, thus providing a balanced unit in operation and reducing effects of vibration. In addition, the flexibility of roller chain plus clearance between the chain rollers and sprocket teeth allow for slight misalignment and shaft end float.

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. It automatically re-engages when the over load torque has passed, no resetting is required. The Nu-Teck torque limiter prevents machine damage and eliminates costly downtime. The Nu-Teck torque limiter utilises spring-loaded friction surfaces for its operations. The slip torque is preset by adjustment of the spring force. The Nu-Teck torque limiter can be used with a sprocket, gear, sheave or flange plate as a center member that is clamped between two friction facings.

Nu-Teck Sprocket Wheels are manufactured from quality materials. Teeth are hob-cut for correct tooth form, tooth thickness and profile. Assuring maximum life of chain and sprocket wheel. Nu-Teck can hob sprockets up to 3" pitch in British or American standards for any no. of teeth and no. of strands. Plate type sprockets can also be supplied in all sizes. Sprockets can be teeth induction hardened or volume hardened as per customer requirements.

We manufacture gears and pinions as per customer requirements.
