high speed bearing Axial bearing

The machine is in operation, the general spindle or drive shaft temperature higher than the adjacent parts of the temperature, so the shaft will heat up elongation. In order to keep the shaft to rotate flexibly, in supporting structure design, while meeting the axial positioning accuracy requirements, but also consider the axial heat free expansion requirements. Axial positioning and axial expansion way is the corresponding.

Adjustment of the bearing high speed bearing‍ clearance is to control the running accuracy of the shaft. The axial position adjusting shaft is in order to meet the specific requirements of some of the gear transmission. For example: in the worm, worm axis must fall in the middle plane worm gear to ensure the correct engagement, so the worm shaft can adjust its position in the axial direction. The bevel gear drive, pitch cone cone vertex two bevel gear must coincide, which required two bevel gear shaft can be axially adjusted.

Ring chain electric hoist dustproof and waterproof

Electric chain hoist Thin section bearings‍ is also called electric chain hoist, hoist is one of the indispensable tool of crane.

Electric hoist chain types are: imported electric chain hoist, super low electric chain hoist, chain electric hoist lifting weight is 0.5t~10t. Electric chain hoist chain is equipped with a chain, the chain electric hoist looks neat appearance, anti rust oil is also equipped with a belt, so as not to use electric chain hoist chain in the chain bag, to prevent rusting of the chain. To extend the service life of the electric hoist.

Ring chain electric hoist is firm and durable, waterproof and dustproof performance is good, the compact forming a small aluminum. But electric chain hoist equipment in order to ensure the safety and Triple row roller slewing bearing‍ own the development of the friction clutch and the upper and lower limit switches, the use of simple and convenient. Electric hoist is also provided with a leakage protection devices and overload protection device, if the maximum gravity is lifting more than electric hoist can bear, electric hoist will automatically cut off power, to avoid the accident which occurs due to overload, not causing harm to use.
