Behavior of some sealing arrangements for machine tool spindles
- Univ. of Illinois, Urbana, IL (United States)
A test stand has been built and instrumented to simulate conditions in the spindle cavity of production machine tools, such as high-speed transfer machines, machining centers, milling machines, etc. The purpose of the simulation is to better understand causes of premature support rolling element bearing failures due to grease degradation and corrosion, from the ingress of coolant vapor. Performance characteristics based on coolant vapor in the test chamber, as measured by relative humidity, chamber temperature and chamber pressure relative to the lab atmosphere were obtained for a radial double-lip seal, labyrinth seal, viscoseal/face seal combination and a mechanical face seal. For the operating conditions considered, the best performance was obtained from the viscoseal/face combination followed by the labyrinth seal. 14 refs., 15 figs.
