One-way backstop bearing principle
A one-way backstop bearing is a type of backstop bearing that can be freely rotated in one direction and locked in the other direction. The metal casing of the one-way backstop bearing contains a large number of rollers, needles or balls, and its rolling seat (hole) is shaped so that it can only roll in one direction and a large resistance in the other direction.

How one-way backstop bearing works
1. Backstop bearing ramp and roller design The ramp and roller one-way clutch consists essentially of the outer ring of the inner diameter of the cylinder, the inner ring with the slope, and a set of rollers that are respectively subjected to the spring force and are always in close contact with the inner and outer rings. composition. As long as the rotation of one of the raceways in its direction of motion has an effect on the other, this arrangement essentially ensures the instantaneousness of the speed of overrun and ensures immediate drive capability. This type of one-way clutch can be used for overtaking, indexing and non-reversal in various environments.
When used as an overrunning one-way clutch, the sloping roller type one-way clutch will be installed in such a way that the outer ring is used as a transmissive member. This is very important for high speed overtaking. In the application of the inner ring transcendence, the centrifugal force acting on the roller will result in a limited speed of overrun. When used as a non-return one-way clutch, a ramp-type one-way clutch with only inner ring rotation is suitable for relatively low speeds. If the required speed is higher than the recommended speed, a wedge type one-way clutch is recommended.
When used as an indexing one-way clutch, the outer ring is often seen as a wobble element and the inner ring is often seen as a slave element. Otherwise, the inertia of the rollers and springs will cause errors, especially at high frequency divisions. The use of diluted lubricants and powerful springs provides high-speed indexing accuracy and high quality.

2. Wedge design of backstop bearing This wedge type one-way overrunning clutch is generally composed of inner ring, outer ring, wedge group, wedge cage, strong spring and bearing. The wedge transfers forces from one raceway to the other by wedging between the inner and outer races. The wedge has two diagonal diameters (ie, the distance from one corner of the wedge to the other diagonal) one of which is larger than the other. The wedge action forces the wedge to have a larger vertical position on a relatively large cross section when the inner and outer rings are rotated relative to each other.

3, backstop bearing self-locking angle wedge mainly depends on the wedge and self-locking angle between the inner and outer rings. The basic concept of a wedge one-way clutch requires that the friction coefficient of the wedge be related to the sudden generation of torque in the inner ring in the drive direction. This friction value must be greater than the tangent of the self-locking angle. If the condition is not safe, the wedge 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 respectively connected by wedges.

The design of the wedge has a very low initial self-locking angle to ensure absolute bonding at the beginning. As the torque increases, a radial force will be created on the wedge that deflects the wedge race, causing the wedge to roll to a new position. Wedges are often designed to have a self-locking angle that can be gradually increased, as it goes from the overrun position to the maximum load bearing position. A relatively large self-locking angle can reduce the radial force generated by the wedge, so that a large torque is allowed to be transmitted as long as the elongation and Brinell hardness limits are required.
