Paper Abstract

Ski lift tower cable sheaves are a maintenance item in that the sheave bearings must be lubricated periodically. Like most other bearings, wear-out failures can occur. Many times the temperature rise ofthe bearing over ambient is a leading indicator ofa bearing failure. Excessive temperature rise due to increased friction in the bearing often precedes any indication ofvibration or dimensional anomalies. Tests were perfonned using two readily available remote temperature sensing devices, the spot imager and scanning infrared camera. Temperature rise data is presented along with a discussion of temperature measuring techniques. Results show that infrared remote sensing is a cost effective means ofchecking the status oflift tower rotating machinery. Keywords: ski lift towers, ski lift tower sheaves, ski lift tower maintenance, bearing friction, bearing failure, infrared camera, infrared spot imaging, temperature rise data, ski lift tower rotating machinery.
