Shaft Extension

Mounting the Shaft Extension

Overview

The shaft extension can be used, for example, to couple an external encoder.

Prerequisites

You need the following tools to mount the shaft extension:

oSoft-faced hammer

oTorque wrench with a set of hexagon sockets

For suitable parts, refer to Replacement Equipment and Accessories.

Procedure Overview

Perform the following procedures to mount the shaft extension:

oPreparing the mounting of the shaft extension

oMounting the shaft extension

Preparing the Mounting of the Shaft Extension

Step	Action
1	Clean all parts.
2	Inspect all parts for damage.

NOTICE

UNINTENDED EQUIPMENT OPERATION

oReplace any damaged parts immediately.

oClean all parts before assembly and use.

Failure to follow these instructions can result in equipment damage.

Mounting the Shaft Extension

Step	Action
1	For CAR40: Insert the shaft extension into the hollow shaft of the rack pinion. Verify that there is no gap between the shaft extension and the rack pinion so that the installation surface is in full contact with the mounting surface of the axis. For CAR41 / CAR42 / CAR43 / CAR44: Insert the shaft extension (2) into the hollow shaft of the toothed belt pulley (1). Verify that there is no gap between the shaft extension and the toothed belt pulley so that the installation surface is in full contact with the mounting surface of the axis. NOTE: To insert the shaft extension completely, you may have to tap the shaft extension at the last 2 mm (0.079 in) slightly with a soft-faced hammer (not on the screw head).
2	Tighten the screw (3) of the shaft extension. Tightening torque: oFor CAR40 / CAR41: 2.9 Nm (25.7 lbf-in) oFor CAR42 / CAR43 / CAR44: 10 Nm (89 lbf-in) NOTE:
