he characteristics of the elastic pin coupling
The coupling has been listed as the national standard gb5014-85, which is suitable for the transmission shaft of two coaxial lines of mechanical connection, usually used for high and low speed movement. Working temperature is 20 ~ + 80 ℃; The transfer torque is 40 ~ 20000n. m.
Low elastic dowel pin shaft coupling with bigger has simple and reasonable structure, convenient maintenance, bilateral symmetry, interchangeable, long life, allows larger axial channeling, buffer, shock absorption, wear-resisting performance, etc.
The axial hole type has cylindrical (Y), conical (Z) and short cylindrical (J). The shaft hole and keyway are machined according to the national standard gb3852-83 "coupling shaft and keyway form and dimension". 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.
Low elastic dowel pin shaft coupling is the use of a number of non-metallic elastic material dowel pin, put in two and a half coupling flange hole, achieved by column pin half coupling, the coupling structure is simple, easy to manufacture, replace the elastic element installation is more convenient, need not move two half couplings. Elastic element (dowel pin) nylon material selection in general, there are two axis offset trace compensation ability, flexible work under shear, work reliability is poor and is only applicable to medium speed transmission shafting with low requirements, the operation condition of the high reliability requirement does not apply to work.
