Example Embodiment
[0024] Example 1: Full-groove self-regulating friction type one-way overrunning clutch C1 with symmetrical double tapered rollers
[0025] Figure 1~2 The clutch C1 shown in 8 belongs to the roller type overrunning clutch. Similar to most clutches of this type, it includes an outer ring 30 that revolves around the same axis X, an inner ring 40, a set of at least one double tapered roller 50 as an intermediate member, and an annular ribbon spring 70 as a pretension spring. .
[0026] Among them, for the convenience of manufacturing, the symmetrical double tapered roller 50 is used for the side surface of the friction contact, and it is best to have a complete truncated conical surface of revolution with two axially symmetric half cone apex angles equal to β, and β = 90 degrees-ρ / 2. Among them, ρ is the angle between the inclined surfaces of the outer ring 30 and the corresponding inner and outer channels of the inner ring 40 in the axial plane. In order to reduce the no-load resi...

[0044] Example 2: Full groove self-regulating friction type two-way overrunning clutch C2 with the same rotating surface
[0045] In fact, like Figure 3A~3B , The clutch C2 shown in 9A-9B is only an improved application of the clutch C1 in the first embodiment, and like the clutch C1, the clutch C2 is also a roller type overrunning clutch, and has the existing technology All functions of the so-called two-way overrunning clutch with pawl.
[0046] Among them, the wire-shaped bow spring 20 instead of the ring-shaped ribbon spring 70 is best made of spring steel wire, see Figure 9A~9B , The radius of curvature of the arc section 22 in the plane-shaped gyration space is optimally smaller than the gyration radius of the gyration circle where the curvature center lines of the double tapered rollers 50a and 50b are located. In order to increase its elasticity and circumferential extension length, the circular arc section 22 is deliberately made into an axial convex shape and formed wit...

[0055] Example 3: Full-channel self-regulating friction type two-way overrunning clutch C3 with different turning surfaces
[0056] See Figure 4~5 , Like clutch C2, two-way overrunning clutch C3 is still a two-way one-way overrunning clutch C1 whose working directions are opposite to each other. The only difference is that the former is a two-way combination of two identical clutches C1 in the same plane rotation space. The latter is a rigid double coupling of two identical clutches C1 in different plane-type rotating spaces, so as to have a carrying capacity completely equivalent to that of the one-way clutch C1.
[0057] Among them, the two sets of oppositely facing outer channels 42a and 42b are arranged at roughly corresponding circumferential positions, and the respective sets of notches 48a and 48b respectively have exactly the same circumferential and radial positions corresponding to each other, and are located at The same axial end of the outer channel 42a or 42b, such as...
