Product description

Information

GN 327 safety clutch handwheels feature the ultimate in health and safety at work standards because the handwheel, if disengaged, is mounted on a fixed component, the bearing flange. The wheel is fully disengaged from the rotating shaft.

The bearing flange can also accept the bearing of the shaft via the bearing bushing (code no. 1). This bearing bushing is a dry bearing (DU bushing). Normally, the shaft has a separate bearing and the bearing bushing serves to center the bearing flange.

Centering can also be effected by a centering ring (code no. 2) if the appropriate bore hole has been made at the machine side. In this case there is no need for the bearing bushings and no bearing friction (heating) will occur.

Assembly Instructions

Shaft bushing and countershaft pulley are delivered in two separate components. Before assembly, make sure that the shaft bushing can be pushed smoothly and free-moving over the shaft.

Proper function is guaranteed only if:

  • shaft bushing and bearing surface are level with each other
  • the shaft axis lies at a right angle to the bearing surface on the machine side.

Design with bearing bushing (identification no. 1)

Push the handwheel and the shaft bushing at the same time over the shaft, bolt down the bearing flange, and fix the shaft bush axially with the countershaft pulley.

Design with centring ring (identification no. 2)

The handwheel can be bolted at once through the centring ring above the bearing flange. Then push the shaft bushing onto the shaft and fix it axially with the countershaft pulley.

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 safety clutch handwheels described under the application notes of GN 000.4, GN 000.5 and
GN 321.6 are characterized by the fact that they require no special machine-side measures for attaching. They are simply pushed over the shaft. However, the inevitable bearing friction generates a link between shaft and handwheel which needs to be kept in mind as specified above.
For applications with very high rotary speed, ultimate levels of safety at work and under continuous operation, the safety clutch handwheel with fixed bearing flange is the best possible solution. The separate bearing configuration means that the user notices given for types 1. to 3. do not apply.
However, this safety clutch handwheel is more complex, with a number of requirements to be met at the machine side.
