Refrigerator Drive belts and couplings

Refrigerator Troubleshooting – Drive couplings

Instead of employing a flywheel and drive options, compressors may be designed for direct coupling.
The coupling on small compressors may be of a rigid flange type. Larger compressors will have a more elaborate resilient coupling similar to that shown in Figure 95, consisting of a flange assembly, a centre ring assembly, a number of forged [...]

Refrigerator Troubleshooting – Drive belts

Correct alignment of the flywheel and drive pulley, and correct tensioning of the drive belt(s), are most important during the installation or replacement of belt(s) or motor. Incorrect alignment and tensioning can result in excessive belt wear, loss of compressor efficiency, and motor failure due to faulty motor or compressor drive shaft bearings.
Alignment
This may be [...]
