Description
type elastic column pin coupling product introduction:
Characteristics of elastic column pin coupling
1. Elastic pin coupling is only suitable for medium speed transmission shaft system with very low requirements, and is not suitable for working conditions with high reliability requirements, because the material of elastic components (pin) is generally selected nylon, which has the ability to slightly compensate the deviation of two axes, and the elastic parts are subjected to shear when working, resulting in poor working reliability.
Second, the elastic column pin coupling has a large structure simple, reasonable, convenient maintenance, two sides of symmetry interchangeable, long life, allowing greater axial movement, with buffer, shock absorption, wear resistance and other properties.
Three, the elastic column pin coupling is made of a number of non-metallic elastic materials of the column pin, placed in the flange hole of the two-half coupling, through the column pin to realize the two-half coupling connection, the coupling structure is simple, easy to manufacture, installation and removal of elastic components is more convenient, do not move the two-half coupling.
The national standard of elastic column pin couplings is gb5014-2003 (the original country label is gb5014-85), elastic column pin couplings are suitable for a variety of mechanical connection with two axes of the drive shaft, usually used for frequent high and low speed movement.Operating temperature is -20 ~ +80℃;The transfer of nominal torque is 40 ~ 20000n. m.The shaft holes of the elastic pin coupling are cylindrical (Y), conical (Z) and short cylindrical (J).The shaft hole and keyway of the elastic column pin coupling are processed according to the national standard gb3852-83 “form and size of shaft column and keyway of coupling”.Half coupling with precision casting, cast iron HT20-40, cast steel ZG35 Ⅱ, axle hole and the keyway USES the drawing forming, dowel pin with MC nylon made from b.

The coupling consists of two hubs:one pin hub with the corresponding pins and a bush hub.The torque is transmitted via the steel pins with their taper elastomer rings and the corresponding bores in the bush hub.
