Ramp and Roller Designs
The use of this type of one-way clutch can be suitable for overrunning, indexing and anti-reverse use in various environments.
When used as an overrunning one-way clutch
Ramp-type roller one-way clutches will be installed in this way, using the outer ring as the overrunning member. This is very important for high speed overtaking. In the use of inner ring overrunning, the centrifugal force acting on the rollers will cause the overrunning speed to be limited.
When used as a non-return one-way clutch
Ramp roller type one-way clutches in which only the inner ring rotates are suitable for relatively low speeds. If the required speed is higher than the recommended speed, it is recommended to use a sprag type one-way clutch.
When used as an indexing one-way clutch
The outer ring is often seen as the oscillating element, and the inner ring is often seen as the slave element. Otherwise, the inertia of the rollers and springs will cause errors, especially at high frequency indexing. The use of diluted oil and strong springs provides high-speed indexing accuracy and high quality.
Wedge design
This wedge type one-way overrunning clutch is generally composed of an inner ring, an outer ring, a wedge block group, a wedge block cage, a strong spring and a bearing. The wedges transfer force from one raceway to the other by wedging between the inner and outer rings. Wedges have two diagonal diameters (the distance from one corner of the wedge to the other diagonally), one of which is larger than the other. Wedge action occurs when the inner and outer rings rotate relative to each other and force the wedges to have a larger vertical position on a relatively large cross-section.
