Of electromotor lubricant
The breed of electromotor and norms size are numerous, the lubricant of general electromotor is chosen depend on bearing type, revolution and temperature, bear.
Small-sized electromotor is commonly used sliding bearing, in bearing inside set oil storage groove or oily Chi Cai uses the annulus that swing oil and oily catenary, circle that swing oil to use lube to lubricate circularly inside axle sleeve, useful also wick is lubricant, the durable life that carries lubricating oil is 20000-4000H.
Medium-sized electromotor is multi-purpose scroll bearing (above of 25mm of Ф internal diameter) , use grease is lubricant, normally one-time backfill grease (the backfill inside bearing makes an appointment with 1/2 fat, after using 1 year, clean again change) .
The likelihood in large electric machinery uses scroll bearing or sliding bearing, two kinds of lubricant are used possibly, general sliding bearing is used oil-lubricated, scroll bearing lubricates with fat.
The bearing temperature of electromotor should be controlled commonly between 65-80, alloy sliding bearing is best under 65. Next watches use oil for electromotor.
