Bearing at high speed
Bearing rotating at high speed, especially the speed close to or exceeds the limit speed of the dimension table records, major should pay attention to the following items:
(1) the use of precision bearing;
(2) the analysis of bearing internal clearance (considering the temperature rise of bearing internal clearance reduction);
Cage (3) the analysis of material type (for high-speed rotation, suitable for use of copper alloy cage or phenolic resin system. But there are also suitable for high speed spinning of synthetic resin molding cage);
(4) analysis of lubrication method (lubrication is suitable for high speed rotating cycle, spray lubrication, and lubrication oil mist lubrication and oil lubrication methods).
