Excessively tight drive belts installed between a motor and a refrigeration compressor pulley may cause what condition?

🔍 Key Concepts

• Effect of belt tension on shaft bearings and radial load • Difference between problems caused by belts too tight vs belts too loose (slippage) • Which bearings are most affected when a side (radial) load is applied by a V‑belt on a pulley

💭 Think About

• Think about what happens to the side load on the shafts and bearings when the belt is pulled extra tight between the motor and compressor pulleys. • Ask yourself whether belt slippage is more likely with loose belts or tight belts, and which answer choices mention slippage. • Consider which bearings would see the greatest additional load: only on one machine, both machines, only on one end of the shafts, or on all bearings along both shafts.

✅ Before You Answer

• Verify whether excessive belt tension primarily increases radial load on the pulley-end bearings of both the motor and the compressor. • Check if belt slippage is logically associated with tight or loose belts before accepting any answer that mentions slippage. • Confirm which bearings are in line with the pulley side load (pulley-end vs opposite-end bearings) when a V-belt is over-tightened.
