One-way bearing structure and working principle

                                              One-way bearing structure and working principle

One-way bearing is free to rotate in a direction, and locked in another direction of a bearing. One-way bearing is also called the non-return device or overrunning clutch. Structure in general have a roller type and wedge type.

One-way bearing is free to rotate in a direction, and locked in another direction of a bearing. One-way bearing is also called the non-return device or overrunning clutch, just according to different industries, the effect is different. One-way bearing metal shell, contains a number of roller, needle or ball, and the rolling (hole) of the shape that it can only scroll in one direction, while in another direction will produce very big resistance (the so-called "one-way").

1, slope, and roller type design

Basic by slope and miler overrunning clutch cylinder diameter of inner ring and outer ring, slope of the spring force and under always closely contact with inside and outside the circle of a set of roller. As long as one of the raceway on the direction of rotation on the output became another, this arrangement is essentially to ensure the speed beyond the ability of immediacy and ensure the driver immediately.

2, the wedge type design

The wedge clutch roughly by the inner ring and outer ring, wedge block group, the wedge of cage, strong springs and bearing. Wedge with wedging between, outer ring from a race to give power to another race. Wedge will have two diagonal diameter, (that is, from the corner of a wedge to another diagonal distance) one more than another. , the interaction between the wedge and the outer ring relative rotation occurs in larger on the cross section of forced wedge more vertical position.
