RISSound of Linear Guideway Type Recirculating Linear Ball Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The sound characteristics of linear guideway type (LGT) recirculating linear ball bearing driven at a constant linear velocity was studied. The measurement results of the sound characteristics ...
Vibrations of the All-Ceramic Ball Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: All-ceramic ball bearings with silicone nitride balls and silicone nitride rings were tested and the vibration characteristics were compared with those of hybrid ceramic ball bearings and ...
Vertical Stiffnesses of Preloaded Linear Guideway Type Ball Bearings Incorporating the Flexibility of the Carriage and Rail
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article deals with the vertical stiffnesses of preloaded linear guideway type ball bearings (linear bearings) incorporating the flexibility of the carriage and rail. First the vertical ...
Running Torque of Ball Bearings With Polymer Lubricant (Running Torque Formulas of Deep Groove Ball Bearings Under Axial Loads)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A running torque analysis was performed on axially loaded deep groove ball bearings lubricated with a polymer lubricant. The analysis included a Type I and a Type II bearing. The Type I ...
Study on Piston Slap Induced Liner Cavitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Liner cavitation induced by piston slap in a diesel engine is caused by water pressure fluctuation when the pressure of coolant falls below saturated vapor pressure. Cavitation erosion of cylinder liners is thought to be ...
Effect of Larch Forest Density on Snow Surface Energy Balance
Publisher: American Meteorological Society
Abstract: It is established that the density of a larch forest strongly influences the snowmelt energy under its canopy. In the spring thaw of 1994, 1995, and 1996, the surface snowmelt at three different sites located at the southern ...
