Customers often ask what the code name in the coupling is and what does it mean. Let me briefly answer this question for you.
First of all, let's talk about the shaft hole code of the coupling, for example:
Active end: J1 type shaft hole, B type keyway, d=20mm, L=38mm
Driven end: J type shaft hole, B1 type keyway, d=22mm, L=38mm
In fact, the shaft hole of the coupling has Y type, J type, J type₁Type, Z type, Z₁Type, Z₂Type, Z₃Type, the most commonly used are the first 3 forms.
Y type-long cylindrical shaft hole
J type-short cylindrical shaft hole with counterbore
J₁Type-Short cylindrical shaft hole without counterbore
Z type-long conical shaft hole with counterbore
Z₁Type-Long conical shaft hole without counterbore
Z₂Type-Short conical shaft hole with counterbore
Z₃Type-Short conical shaft hole without counterbore
Besides, the connection forms of the lower keyway are A type, B type, B₁Type, C type, D type, U type, UI type, UZ type, the first 3 types are commonly used.
A type-flat key single keyway
Type B-120° layout flat key double keyway
B₁Type -180°layout flat key double keyway
C type-conical shaft hole flat key single keyway
D type-cylindrical shaft hole common tangential keyway
U-Cylindrical Interference Connection
UI type-stepped cylindrical interference connection
UZ type-cone interference connection
