One-way bearing working principle and structure design

Refers to the so-called 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 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 ( Acupuncture point) Shape so that it can only scroll in one direction, while in another direction will produce very big resistance ( The so-called 'one-way') 。 One-way bearing principle of work: the general principle of the one-way bearing is clamping principle, used for clamping roller in the working face is a slope, in roller bearing down turn is downhill, against the turn is uphill, available in the form of irregular cheese block overrunning clutch is also the same working principle. One-way bearing structure design: 1, slope and slope and roller overrunning clutch roller type design by the cylinder diameter of inner ring and outer ring, slope of the spring force and always under 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 of the sphenoid starting 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, From the corner of the wedge to the other diagonal distance) One of them is greater 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. 3, self-locking wedge Angle relies mainly on the inside and outside the circle wedging and self-locking wedge between Angle. The basic concept of wedge overrunning clutch for wedge friction coefficient and inner ring suddenly produce torque on the driving direction, the friction values must be bigger than self-lock Angle of tangent value. If the conditions are not safe, wedge will not occur. Self-lock Angle is determined by the structure of the wedge, the points on the inside and outside the circle use wedge and its connection respectively. In the design of the wedge has a very low initial self-lock Angle to ensure that at the beginning of the combination of absolute. With the increase of torque, wedge will produce a but make roll wedge deflection of radial force, caused the wedge roll over to a new location. Wedge is often designed to have a self-locking Angle can increase gradually, and the position until it from beyond the location of the maximum load bearing - The sample. Larger self-locking Angle can reduce the radial force produced by the wedge block into, so as long as at the request of the elongation and brinell hardness limit allows large torque is passed. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
