One-way clutch bearing

Abstract

The invention relates to a one-way clutch bearing. In the axial direction, an outer ring and an inner ring are divided into a rolling body mounting section and a rolling needle mounting section; a roller path is arranged on the outer ring inner wall and the inner ring outer wall of the rolling body mounting section; a plurality of rolling bodies are arranged in the roller path on the outer ring and the inner ring; a rolling body holder is used for uniformly separating the plurality of the rolling bodies; a plurality of rolling needle groups are arranged between the outer ring inner wall and the inner ring outer wall of the rolling needle mounting section; a rolling needle holder is used for uniformly separating the plurality of the rolling needle groups; each rolling needle group comprises a first rolling needle and a second rolling needle; each first rolling needle and each second rolling needle are arranged in a holding slot of the rolling needle holding frame; a pressure angle is formed between a center connecting line of the first rolling needle and the second rolling needle and a contact pressure direction of the inner ring; each first rolling needle is positioned at the radial inner end of the holding slot, and is in contact with the outer wall of the inner ring; and each second rolling needle is positioned at the radial outer end of the holding slot, and is in contact with the inner wall of the outer ring. The one-way clutch bearing is simple and compact in structure, is good in processing process and is high in precision; and product quality is guaranteed.

Description

technical field [0001] The invention relates to a one-way clutch bearing. Background technique [0002] One-way clutch bearing is a kind of bearing, which is characterized by the function of one-way rotation and reverse stop, and is widely used in one-way clutches of washing machines, one-way clutches of automobiles and one-way clutches of electric automatic vehicles. At present, the basic principles of the one-way clutch bearings at home and abroad to realize the one-way function mainly include the following schemes: a structure such as figure 1 As shown, the raceways of the inner and outer rings of the one-way clutch bearing are circular, and the stop in the middle is a detent that forms a parabolic shape on the outside; another structure is as follows figure 2 As shown, the inner ring and rolling outer circle of the one-way clutch bearing are circular, and the raceway of the outer ring is multi-shaped; there is also a structure such as image 3 As shown, the outer diam...

Problems solved by technology

At present, the basic principles of the one-way clutch bearings at home and abroad to realize the one-way function mainly include the following schemes: a structure such as figure 1 As shown, the raceways of the inner and outer rings of the one-way clutch bearing are circular, and the stop in the middle is a detent that forms a parabolic shape on the outside; another structure is as follows figure 2 As shown, the inner ring and rolling outer circle of the one-way clutch bearing are circular, and the raceway of the outer ring is multi-shaped; there is also a structure such as image 3 As shown, the outer diameter of the outer ring raceway and the rolling body is circular, and the inner ring raceway is made into a multi-tap shape. The principle of realizing one-way is to rely on the wedge-shaped part on the inner ring raceway to realize the stop. This strange shape The characteristics of the production process have brought great difficulties

To sum up, in the above-mentioned several structures, whether it is to set multi-slip grooves on the inner ring or outer ring, or to make the rolling elements into a parabolic shape, the processing technology is very complicated, and the precision is poor, and the product quality cannot be guaranteed.
