Product Description
The JMIIJ Double Key Elastic Diaphragm Coupling are different from the common diaphragm couplings. They not only connect the intermediate shaft, extend the transmission distance, but also have two diaphragms to increase the flexibility compensation amount, so they are also called double diaphragm couplings.
JMIIJ Double Key Elastic Diaphragm Coupling can accurately transfer speed, operation without rotation difference, and can be used for precision mechanical transmission. The transmission efficiency is up to 99.86% in the transmission, especially for medium and high speed high power transmission. It is simple in structure, light in weight, small in volume and convenient in assembly and dismantling. Do not have to move the machine to install, without lubrication. It can move safely under the condition of shock and vibration. It has obvious shock absorption, no noise, no wear and tear.
Application
1. Include power transmission to industrial equipment such as pumps, gear boxes, compressors, blowers, mixers, and conveyors.
2. Widely used in various mechanical and hydraulic fields
3. Small dimension, low weight, high transmitted torque
4. Elastomers made of polyurethane with shore hardness between 80-98
5. Compensating the axial relative drift, buffer and vibration reduction
6. Material:steel and aluminum alloy
