Figure 6-5. Theta Drive Shaft Bushing Replacement Kit
Version Information:
Bushings can only be replaced on certain theta drive shaft
models. Inspect the cylindrical outer section of the drive shaft to determine
which model is installed on your robot. For theta drive shafts that feature screws
on the cylindrical outer section, the bushings can be replaced.
For theta drive shafts that feature a smooth cylindrical outer section without
screws, bushings are not serviceable and the theta drive shaft must be
replaced. Contact your local OMRON representative for more information
Theta Drive Shaft Bushing Replacement Procedure
Use the following procedure to replace the theta drive shaft bushings.
IMPORTANT:
Do not rotate the drive shaft or the lower U-joint during this pro-
cedure. If either is rotated, the calibration data for joint 4 will be lost, requiring
recalibration. Refer to Aligning the Platform with the Joint 4 Motor on page 110
1. Remove power from the robot.
2. Remove the lower U-joint drive shaft set screw to disconnect the lower U-joint from the
theta drive shaft while leaving the U-joint connected to the platform shaft. Do not dis-
connect the upper U-joint.
