DC Series Gear Drum Coupling(Q/LZP02.07-2005)

This standard is applicable to the connection between the output shaft of the reducer of the lifting mechanism and the copper wire rope reel in lifting equipment, as well as other similar mechanical equipment that both transmits torque and bears radial loads.
However, it cannot be used as a transmission subject to axial load.

Note:
R/min= Allowable speed of rotation; N.m= Norminal torque; N= Radial load; d= Diameter of shaft hole; 
L= Length of shaft hole; S n-d2 a d3= Size of drum connection size; m3= Wear and tear scale;
Xmax= Axial clearance; e= Loading location; l= Rotational inetia; m= Mass
1. The maximum shaft deviation angle this couplings is ±0°30′.
2. The connection thread of lubricating oil hole is Rcl/4.
3. Both the moment of inertia l and the mass m are approximate values for reference only
4. With the new revision of the standard products, the change of the material and the progress of technology, the information in this document is subject to change. No further notice will be given.
