Abstract

A device to connect at least two components to each other properly. It is arranged so that one component has one pin element (1) and the other assembly has a recess (2), one for at least one such pin (1) area of the pin ( 1) This has at least one cam (5) in its peripheral direction. Where this cam extends radially Beyond the imaginary cylindrical surface (4) on one side, and such a support slot has a number of grooves in its peripheral direction that are concave in the line The radius from the cylindrical surface in imaginary (7) on one side, where the groove These correspond to the cam (5) and cam (5), and the groove (8) is formed into the wedge profile. Whose wedge surface (6, 9) has the shape Along one logarithmic spiral path When compared With the axle of the pin (1) and the support hole (2) thereof, by the pitch sequence or the taper of the joint wedge face (6, 9) with the same quantity. And that was created in order This causes the interlocking friction overlap of the pins (1) and the support compartment (2) due to the given relative motion. This overlap is achieved in the radial and axial directions between pins (1) and supports (2) regardless of the direction of rotation. And the direction of gravity or weight When contact of a joint wedge surface (6, 9) occurs by creating a joint or a certain pressure gap, and therefore a gap-free nature.

Claims (6)

1. a device that has at least two components Where one component has One of the pins (1) and the other component has a recess (2), one for supporting the pin (1) at least one area of the pin (1) has at least one cam (5). In its peripheral direction Which stretches along the radius beyond the contour surface The imaginary cylinder (4) and the support compartment (2) have a number of grooves that correspond to the eccentric ball (5) in their peripheral direction. Which is radial concave entering from the imaginary cylindrical surface (7) and cam (5) and groove (8) are designed in the shape of a contour. The wedge, which is characterized by that the wedge surface (6, 9) of the cam (5) and of the groove (8), travels a literal spiral path. It is related to the axis of the pin (1) and the support hole (2). The pitch or taper of the working surfaces of the wedge face (6, 9) with the same amount. One quantity is designed to be very flat due to the determined relative motion between the pins (1) and the support (2) after the contact of the combined wedge surface (6, 9), which makes Born Increased by creating joint pressure, so without loosening Frictional overlap Self-tightening is provided in radial and in axial direction between pins (1) and support (2) regardless of the direction of rotation. 2. The device is indicated in claim 1, where each of the three wedge-shaped structures, one placed behind the other.
