1.Ramp and roller type design The slope and roller type one-way clutch is composed of the outer ring of the cylinder inner diameter, the inner ring with the ramp and a set of rollers which bear the spring force and are always in close contact with the inner and outer ring. As long as one of the raceways rotates in the direction of its movement to another, the arrangement essentially ensures that the speed is instantaneous and the immediate drive capability is Guaranteed. The use of this type of one-way clutch can be used in a variety of environments, such as the transcendence, the degree of separation and Reverse. When used as a beyond-one-way clutch The slope type Roller type unidirectional clutch will be installed in this way, that is, the outer ring as a transcendental member. This is important for high-speed transcendence. In the application of the inner ring transcendence, the centrifugal force acting on the rollers will lead to the exceeding speed Limitation. When used as a non-inverting one-way clutch Only the inner ring rotation of the ramp roller type unidirectional clutch is suitable for a lower speed. If the required speed is higher than the recommended speed, a wedge-type unidirectional clutch is Recommended. When used as a sub-dimensional one-way clutch The outer ring is often seen as a swinging element, and the inner ring is often seen as a slave element. otherwise, the inertia of the rollers and springs will result in errors, especially at high frequency degrees. The use of diluted lubricants and strong springs provides high-speed accuracy and high-quality of the Grade.
2.Wedge-block Design This wedge-type unidirectional overrunning clutch is generally composed of an inner ring, outer ring, wedge block, Wedge cage, Strong Spring and Bearing. The wedge transmits strength from one raceway to the other by the wedge between the inner and outer rings. The wedge has two diagonal diameters (that is, the distance from one corner of the wedge to the other), one of which is greater than the Other. Wedge action occurs when the inner and outer rings are rotated relative to the larger cross section forcing the wedge to have a larger vertical position.
3. The self-locking wedge is mainly dependent on the wedge between the inner and outer rings and the self-locking angle. 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, which must be greater than the tangent of the self-locking angle. If the condition is not secure, the wedge will not occur.
