Selection of Coupling Shaft Hole Counterbore

XINLAN analysis selectionCouplingWhen the shaft hole chooses whether to have a counterbore, it mainly depends on whether the shaft can move axially, and does not require axial tension or installation space.
       There are three types of shaft holes for couplings: Y-type, J-type, and Z-type.
The Y-shaped shaft hole is a long cylindrical shaft hole.
The J type shaft hole is divided into J type and J1 type. J type is a short cylindrical shaft hole with counterbore, and J1 type is a short cylindrical shaft hole without counterbore.
Z type shaft hole is divided into Z type and Z1 type, Z type is a short conical shaft hole with counterbore, and Z1 type is a short conical shaft hole without counterbore.
 The taper of the Z-shaped shaft hole is 1:10.
