Introduction and application of clutch one way bearing
A clutch one way bearing is a bearing that can rotate freely in one direction and lock in the other direction. One-way bearing is also called beyond the clutch, but according to different industries, different roles to name. The metal shell of a one-way bearing contains many rollers, needles or ball bearings, and the shape of its rolling seat (hole) makes it roll only in one direction, while there will be great resistance in the other direction (the so-called "one-way").
Powder metallurgy Unidirectional bearings are made of metal powder (or a mixture of metal powder and nonmetal powder) by forming and sintering processes. On the basis of studying the characteristics of powder and process characteristics, the corresponding technical process is adopted to change the shape, performance and organizational structure of powder to become bearing products to meet different needs.
The one way bearing manufacturer uses GCr15 bearing steel when making solid one-way bearings. After heat treatment, the hardness is in HRC61-65. The bearing is small in volume and has high bearing capacity. Powder metallurgy unidirectional bearings and solid unidirectional bearings can completely "lock" the drive shaft when it is driven, avoiding the problem of insufficient "lock" performance of traditional stamping outer ring unidirectional bearings.
Main uses: textile machinery; Printing machinery; Automobile industry; Household appliances; Money detector, according to the use of different will have different one way bearing price.
Unidirectional needle roller bearing: it is composed of stamping outer ring and plastic cage, which can have its own plastic reed or stainless steel reed guide needle roller. The bevel raceway and needle roller on the outer ring are used as locking device. HFL(Clutch and Bearing assembly) : Support bearings are mounted on both sides of the needle roller clutch and bear radial load. As support bearings are needle roller and plastic cage assembly. Because there is no inner ring, the shaft wear is greater, so it is best to use the shaft heat treatment.
