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
