Double Roller Chain Coupling

Double Roller Chain Coupling

Description
A double roller chain coupling consists of one duplex roller chain and two sprockets. Both shafts can be easily coupled or decoupled with a single joint pin inserted into or extracted from the roller chains. Since a powerful roller chain is engaged with the sprockets at all the teeth, a large torque can be transmitted. Although the coupling itself is smaller than other kinds of couplings.

Application
Double roller chain coupling can be used in textile, agricultural, lifting transportation, engineering, mining, light industry and chemical engineering machinery. This shaft coupling is suitable in high temperature, damp and dusty working conditions.

Features
1. The clearances between the chains and sprockets or between chain components absorb the great positional misalignment of both shafts.
2. The roller chain of this double roller chain coupling is made of heat-treated steel and manufactured precisely to the highest manufacturing standard.
3. Rational flexibility decreases vibration, overheating and wear of the bearings caused by the angle errors of the shafts.
4. Transmitting torque of this double roller chain coupling is 40 to 25000 N.m
