GN 000.5 Steel Safety Clutch Assemblies, for Safety Clutch Handwheels, with Needle Bearing

Standard Sheet GN 000.5 Print This Page More Information on Safety Clutch Handwheels Keyways P9 DIN 6885-2 ISO Fundamental Tolerances

Product description

The use of needle bearings and the hardened bearing surfaces make the clutch engagement extremely smooth. This is also assisted by the finer serrations and the increased length of the clutch assembly.

The use at higher shaft speeds and the longer service life are further advantages of the needle bearing.

An oil hole is provided which is connected to a pressure oiler in the wheel hub when the safety clutch handwheel is completely assembled.

The coupling attachment is axially secured in the handwheel hub by a clamping nut.

Application Notes

The relevant health and safety at work provisions state that handwheels must be attached to spindles such that they are not turned along together with the machine drive assembly. Safety clutch handwheels meet this requirement:

If not in operation, the wheel is disengaged. Shifting it in axial direction (pushing or pulling) will intermesh two serrated bushings, engaging the wheel with the shaft.
After releasing, the wheel will disengage again automatically.

A number of user notices for various design types are listed below. These notices are non-binding and given without liability. They do not constitute a warranty of proper function. The user must in any case determine whether the safety clutch handwheels are suitable for the intended purpose and use.

The details given at the application notes of GN 000.4 apply in principle also to these safety clutch handwheels.
With their needle bearings, they have the advantage over friction bearings that they can be used for somewhat higher speeds due to their substantially lower friction, lower wear and tear and lower sensitivity to lubrication.
Owing to their larger construction length and lower friction (hardened contact surfaces) and finer intermeshing, these wheels are also easier to engage.
