Z Series-Keyless Locking device Z8:

1.Shaft collar selection method

Choose shaft collar according to load

1.select the shaft collar should meet:

a. transmitted torque Mt ≥ M

b. axial force:Ft ≥ Fx

c. transfer force:Ft ≥ F2X+(M X10-3)2

d. radial force Pt ≥ Fr/d.1 X103

2,the rated load of a connection which to use numerous shaft sleeve.

When Rated load of a shaft sleeve is less than required transfer load, then can set more than two shaft sleeves in series, the total rated load:

Mtn=m.Mt

Type in: Mtn - n shaft sleeve’s rated load:M - load coefficient (m value shown in chart A)
