One-way bearing is free to rotate in one direction, while in the other direction to lock a bearing. Also called a one-way clutch bearing, but depending on the industry, the role of different named.
The metal in the one-way bearing, comprising a number of rollers, roller or ball, and the rolling seat (hole) shape rolling it in only one direction and in the other direction generates a large resistance (The so-called "one-way").
Entity using one-way bearing GCr15 bearing steel, heat-treated hardness HRC61-65, bearing small size and high load carrying capacity, there is enough storage space for grease, may have come a long lubrication intervals.
The wedge block overrunning clutch uses a special-shaped wedge block instead of a roller as a wedge tightening member. It is a clutch that uses a wedge block and inner and outer raceways to form a friction pair.
When there is no relative movement between the inner ring, the outer ring and the wedge, the steering is the same and the rotation speed is equal, the torque can be transmitted, otherwise they are all relative slip.
This sliding state that does not transmit torque is called overtaking. Wedge overrunning clutch mainly includes basic type, no inner ring type and bearing type.
The connection form is divided into key connection, gear connection, pulley connection, sprocket connection, bolt connection, etc.
Main purpose: textile machinery; printing machinery; automobile industry; appliances; detectors.
