Replacing the Elastomer Coupling (Optional Equipment)

Overview

Replacing the elastomer coupling can cause unintended movements.

Warning_Color.gifWARNING

UNINTENDED MOVEMENTS DUE TO DISMOUNTING

Secure the moving parts of the axis mounted in a vertical or tilted position against unintended movements.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Prerequisites

You need the following tools to remove the elastomer coupling:

oSet of hex keys

oSoft-faced hammer

NOTE: Do not use ball head hex keys. Excessive torque may cause the ball head to tear off. A torn off ball head is difficult to remove from the screw.

For suitable parts, refer to Replacement Equipment and Accessories.

Procedure Overview

Perform the following procedures to replace the motor and/or gearbox:

oPreparing the replacement of the elastomer coupling

NOTE:

7

Carefully tap on the screw head with a soft-faced hammer to loosen the cone of the expanding hub.

NOTE: If you cannot reach the screw head, use a hex key as extension and tap carefully on the hex key.

8

For CAR40: Pull the expanding hub carefully out of the hollow shaft of the gear rack pulley.

For CAR41 / CAR42 / CAR43 / CAR44: Pull the expanding hub carefully out of the hollow shaft of the toothed belt pulley (8).

NOTE: This may require a considerable force.

9

Mount the new elastomer coupling as well as the motor or and/or gearbox as described in Mounting the Motor and/or Gearbox.
