DC series for the wedge-type one-way clutch, no internal and external ring, from the double cage to maintain the wedge, the selection should be in accordance with the customer requirements of the design of the inner and outer ring, while in use, to attach rolling bearings to withstand axial and radial loads, because the curvature of the wedge is larger than the roller, loading capacity, So it has a larger torque capacity than the same size roller clutch. Wedge block is the use of anti-friction materials, and because of its own special structure, so that the inner and outer ring contact surface of the wedge also changes accordingly, life is greatly extended.
The function of the self-locking angle wedge mainly depends on the wedge and self-locking angle of the wedge between the inner and outer rings. The basic concept of the wedge one-way clutch requires that the friction coefficient of the wedge is related to the sudden torque generated by the inner ring in the driving direction. This friction value must be greater than the tangent value of the self-locking angle. If conditions are unsafe, wedging will not occur.
The self-locking angle is determined by the structure of the wedge, and the points on the inner and outer rings are connected with wedges respectively.
The wedges are designed with a low initial self-locking angle to ensure an absolute initial bond. As the torque increases, a radial force will be generated on the wedge that deflects the wedge raceway, causing the wedge to roll to a new position. Wedges are often designed to have a self-locking angle that gradually increases from the override position to the maximum load-bearing position. A relatively large self-locking angle can reduce the radial force generated by the wedge, thus allowing greater torque to be transmitted as long as it is within the requirements of the elongation and Brinell hardness limits.
Main uses of one-way bearings: textile machinery; printing machinery; automobile industry; household appliances; banknote detectors.
These bearings are suitable for applications where equipment and components are required to be simple, such as for agricultural machinery, transportation systems or construction machinery. We can produce OEM bearings as your design or sample.
