There are many types of bearings, among which there is a special bearing, I don't know how much you know, one-way bearings, and then I will popularize the type and production method of single bearings for everyone.
A single direction bearing is a bearing that rotates freely in one direction and locks in the other. Single direction bearings are also called overrunning clutches, but they are named according to different industries and different functions. The metal housing of a single direction bearing contains many rollers, needle rollers or balls, and the shape of its rolling seat (cavity) allows it to roll in only one direction and generate great resistance in the other direction (so-called "one direction").
Powder metallurgy unidirectional bearings use the forming and sintering process to make metal powder (or a mixture of metal powder and non-metal powder) into products. On the basis of studying the characteristics of powder and the characteristics of process changes, the corresponding technical process is adopted to change the shape, performance and structure of powder and become bearing products that meet different needs.
Solid one-way bearings use GCr15 bearing steel, the hardness after heat disposal is HRC61-65, the bearing is small in size and has high load-bearing capacity, there is enough space to store smooth grease, and there can be a long smooth distance period. Powder metallurgy single direction bearings and solid single direction bearings can completely "lock" the propeller shaft when subjected to driving force.
It prevents the lack of "locking" performance of traditional stamped outer ring unidirectional bearings, and is mainly used: textile machinery; Printing machinery ; automotive industry; Household appliances; Money detector. Series single direction needle roller bearings: Consists of a stamped outer ring and a plastic adhering frame that can be supplied with a plastic reed or a stainless steel reed to guide the needle roller.
Beveled raceways and needle rollers on the outer ring are mounted as locks. HFL (Clutch and Bearing Assembly): Support bearings are mounted on both sides of the needle roller clutch and accept radial loads, and the support bearings are needle roller and plastic sticking frame assemblies. Since there is no inner ring, the wear on the shaft is large, so it is better to stop the heat disposal of the shaft.
