DR encoder coupling

Diaphragm consists of several groups with bolts staggered with two coupling halves, each of the diaphragm by a set number of sheets stacked together, diaphragm coupling by elastic deformation of the diaphragm to compensate for the relative displacement of the two axes of the Union, is a high-performance metal stronger coupling element, do not run oil, more compact structure, high strength, long life, no rotation gap, independent of temperature and oil slicks, with acid, alkali corrosion, suitable for high-temperature, high-speed, medium corrosive environmental conditions of the drive shaft

Steel hubs are zinc plated.
They are precision swaged by a lifetime crimp to unique double loop element made form ELASTACAST polyurethane.
The hubs fix to sharts by metric set screws.
Maximum operating temperature is 80ºC.

Flexible couplings are usually cut from a metal wire rod made of commonly used materials are aluminum, stainless steel, engineering plastics. Flexible coupling using a parallel or helical grooving system to adapt to a variety of bias and precision torque transmission. Flexible couplings usually have good performance and price advantage, and in many stepper, servo system, the practical application, elastic coupling is the preferred product. One-piece design allows flexible couplings to achieve a zero gap torque transmission and without maintenance

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.
