Find high quality elastic pin coupling with competitive price here. Please rest assured to buy elastic pin coupling with Xinxiang City Xinsheng Mine Manufacturing Co.,Ltd

The national standard is the GB5014-2003 (the original GB number for the GB5014-85), flexible pin coupling for a variety of mechanical coupling two coaxial axis of the drive shaft, usually used for frequent high and low speed movement. Working temperature of -20 ~ +80 ?; transmission nominal torque of 40 ~ 20000N.m. Elastic pin coupling Shaft hole type has cylindrical (Y), conical (Z) and short cylindrical (J). Elastic pin coupling shaft hole and keyway according to the national standard GB3852-83 "coupling shaft and keyway form and size" of the provisions of processing. Semi-coupling with precision casting, cast iron HT20-40, cast steel ZG35 ?, shaft hole and keyway with drawing, the pin made of MC nylon b made.

Elastic pin coupling features:

First, the elastic pin coupling is only suitable for low-speed medium-speed drive shaft, does not apply to the work of high reliability requirements, because the elastic components (pin) materials generally use nylon, a slight compensation Two-axis offset capacity, elastic pieces of work by cutting, poor job reliability.

Second, the elastic pillar coupling has a large structure is simple, reasonable, easy maintenance, symmetrical interchangeable, long life, allowing a larger axial movement, with a buffer, shock absorption, wear and other properties. Stick pin coupling

Third, the elastic pillar coupling is the use of a number of non-metallic elastic material made of the pin, placed in the flange half of the coupling flange, through the pin to achieve the coupling of the two halves, the coupling structure is simple , Easy to manufacture, install the replacement of flexible components more convenient, do not move the two halves coupling.
