Abstract
The invention relates to an interaxial one-way clutch, which comprises a driving shaft, a driven shaft, a roller, an actuating element and the like. When the rotating speed of the driving shaft exceeds that of the driven shaft, the two shafts are combined through the roller and groove structures between the two shafts, and the rotating speeds are the same. When the speed of the driving shaft is lower than that of the driven shaft, the two shafts are naturally separated, and the respective motion states are kept unchanged and are not interfered with each other. When other structural characteristics are matched, axial force transmission, axial motion driving and the like can be realized.

The roller bearing further comprises a retainer, and the rollers are mounted on the retainer.
The actuating element acts on the cage to move the rollers towards the shallow ends of the pockets.
The roller is in a frustum shape, and the vertex of the roller is positioned on the central line of the driving shaft and the driven shaft.
The roller is pressed and self-locked with the driving shaft and the driven shaft, namely, when the roller is pressed between the end faces of the driving shaft and the driven shaft, the roller cannot move along the axial direction of the roller.
The groove for installing the roller can be arranged on the end face of the driving shaft and also can be arranged on the end face of the driven shaft.

Detailed Description
An embodiment of the present invention will be described in detail with reference to fig. 1.
As shown in figure 1, the one-way clutch between shafts comprises a driving shaft (4) and a driven shaft (5), wherein the two shafts are arranged on the same straight line, one end of the driven shaft (5) is provided with a wedge-shaped groove in the circumferential direction, and a roller (1) and an actuating spring (2) are arranged in the groove. The rollers (1) are mounted on the cage (7) and are arranged uniformly in the circumferential direction, and the springs (2) are actuated to move the rollers (1) towards the shallow ends of the grooves. The end face of the driving shaft (4) is in contact with the roller (1) and is not in contact with the end face of the driven shaft (5).
When the distance between the end A of the driving shaft (4) and the end B of the driven shaft (5) is unchanged, namely the other ends of the two shafts are fixed, the driving shaft (4) rotates, the friction force between the end surface and the roller (1) enables the roller (1) to move to the shallow end of the groove, the roller (1) is clamped between the driving shaft (4) and the driven shaft (5), the two shafts are combined and connected into a whole, and the movement states are the same. The driving shaft (4) rotates reversely, the friction force between the end surface and the roller (1) enables the roller (1) to move towards the deep end of the groove, the driving shaft (4) is separated from the driven shaft (5), and respective motion states are kept without mutual interference.
When the A end is fixed, the B end is not fixed, the driven shaft (5) is fixed in the circumferential direction and cannot rotate, the driving shaft (4) rotates to enable the roller (1) to move towards the shallow end of the groove, and the driven shaft (5) cannot rotate, so that the roller (1) pushes the driven shaft (5) to move rightwards to transmit axial thrust and motion. When the driving shaft (4) rotates reversely, the two shafts are separated and do not interfere with each other.
When the B end is fixed, the A end is not fixed, the driven shaft (5) is fixed in the circumferential direction and cannot rotate, the driving shaft (4) rotates to enable the roller (1) to move towards the shallow end of the groove, and the driven shaft (5) cannot rotate, so that the roller (1) pushes the driving shaft (4) to move leftwards to transmit axial thrust and motion. When the driving shaft (4) rotates reversely, the two shafts are separated and do not interfere with each other.
The present invention has been described in connection with the accompanying drawings, and it is to be understood that the invention is not limited to the specific embodiments disclosed, but is intended to cover various modifications, adaptations or uses of the invention, and all such modifications and changes are intended to be included within the scope of the invention.
