The working principle of one way bearing with keyway?

Technical principle of one-way bearing with keyway.

A one-way bearing with keyway is a bearing that is free to rotate in one direction and locked in the other. The metal housing of a one-way bearing with keyway contains many rollers, needle rollers or ball rollers, and the shape of the rolling seat (cavity) makes it only roll in one direction, while in the other direction will produce a large resistance.

The working principle of the one-way bearing with keyway.

1. Sprag design
This type of sprag freewheel consists roughly of an inner ring, an outer ring, a sprag group, a sprag cage, a strong spring and a bearing. The sprags are wedged between the inner and outer ring to transmit the force from one raceway to the other. The wedge has two diagonal diameters, (i.e., from one corner of the wedge to another pair of corners of the distance) one of which is larger than the other. The wedging action occurs when the inner and outer rings rotate relative to each other forcing the wedge to have a larger vertical position in a larger cross section.

2. Self-locking angle wedge action mainly relies on the wedge between the inner and outer ring wedge and self-locking angle.

3. Ramp and Roller Type Design
The ramp and roller freewheel basically consists of an outer ring with a cylindrical inner diameter, an inner ring with a ramp and a set of rollers that are subjected to spring forces and are always in close contact with the inner and outer ring. As long as the rotation of one of the rollers in its direction of motion affects the other, this arrangement essentially ensures immediate overrunning speed and guarantees immediate driving capability.
This type of freewheel is suitable for overrunning, indexing and stopping in various environments.
When used as an overrunning freewheel, the Ramp Roller Freewheel is installed in such a way that the outer ring is used as the overrunning member. This is very important for high-speed overrunning. In the case of an inner ring overrunning, the centrifugal force acting on the rollers will cause the overrunning speed to be limited.

How to care for one-way bearings with keyways.

The maintenance of bearings is much the same. The relative motion of the rolling element and raceway and the intrusion of contaminants and dust cause the rolling element and raceway surfaces to wear. It affects the accuracy of the main machine. Silent machinery with the bearings, the usual maintenance is mainly to prevent the invasion of pollutants and dust. Can choose to improve certain technical measures to move forward, in order to arrive at a more satisfactory need. Change lubrication methods, such as the use of oil and gas, oil mist and spray lubrication; improve cooling conditions.

1.The influence of life

Different cleanliness of the lubricant has a great influence on the life of the ball bearing. Therefore, improving the cleanliness of lubricating oil can extend the life of the bearing.

2.Influence of noise

Cleanliness seriously affects the vibration level of the bearing, especially the vibration of high frequency band is more significant. Bearings with high cleanliness have low values of vibration speed.

3.Influence of bearing grease

Preventing the metamorphosis and accelerated aging of grease affects whether the lubricating function of grease decreases.
