Choose in what circumstances of motor bearing grease or oil, bearing tell you

Motor bearing lubrication in high speed, high temperature, under the standard of grease has not fit can be used lubricating oil.
According to the lubrication oil circulation system, can bring a lot of heat.
Characteristics is the key of the lubricating oil viscosity, viscosity dilution degree of harm of lubricating oil of liquidity and the friction between the oil slick, work temperature of motor bearing lubricating oil viscosity is usually 12 -
15cst。
Speed is higher than the should take low viscosity, the more load weight should take higher viscosity.
Common mechanical lubricating oil, lubricating oil are high speed mechanical lubricating oil, turbine oil, compressor oil, insulating oil, cylinder oil, etc.
Oil lubrication method includes: a.
Oil bath lubrication oil bath lubrication is the most general way of lubrication, suitable for low and medium speed bearing lubrication, motor bearing part in the tank, the lubricating oil by the bearing parts of rotation, and then flow into the tank oil level should be slightly less than the minimum at the center of the roller.
b。
Oil lubrication oil lubrication for have to ration oil bearing components, spill every 3 - in general
A drop of it is advisable to 8 seconds, excessive residual oil will cause motor bearing temperature increase.
c。
Circulation lubrication with gasoline pump will be handed to the blocking of oil bearing structures, according to the bearing lubricating oil filter again refrigeration after application.
Because of the oil circulation system can bring a certain calorific value, make the bearing temperature reduction, therefore method for speed higher bearing components.
d。
Spray lubrication with dry air compressed by the sprayer and lube oil blending produce welding soot, spewing bearing, cyclone can make motor bearing temperature reduction and reasonably can avoid residue invasion.
This method is suitable for high speed, high temperature lubrication of the bearing components.
e.
Spewing oil lubrication with a petrol pump high pressure shot into the bearing, the nozzle into the bearing of the bearing at the other end into the oil in the tank.
In high speed bearing, double twist and the ball bearing is at very high rotational speed peripheral gas generated cyclone, with general lubrication method is difficult to be sent to the bearing lubricating oil, lubricating oil in this time be sure to use high pressure Wells of spray to the bearing, the nozzle part should be in the inner hole and bearing center.
