Embodiment Construction

[0027] FIG. 4 therefore shows a cross section through a belt tensioning system 1 with eccentrically arranged tensioning pulleys. The belt tensioning system 1 comprises a lower cylindrical housing 3 and an upper cylindrical housing 5 which have an outer diameter and an inner diameter which are as equal as possible. The cylindrical housings 3 and 5 interact axially in such a way that they can rotate relative to each other about a longitudinal axis 6 . The upper cylindrical housing 5 contains a side-mounted lever 8 , where the tensioning wheel is fastened by a screw 9 .

[0028] The radial inner surface of the upper cylindrical housing 5 is connected in a rotationally fixed manner to the axial end of a hollow pin 2 . The outer pin 2 has a rotationally fixed disk 4 on its other end, a friction plate 13 is arranged on its circular surface towards the lower cylindrical housing 3, and the friction plate 13 is mounted on the upper cylindrical housing 5, During the rotational movemen...

Abstract

The invention relates to an end profile on slide bearing complementary elements, which comprises a pin (22) and at least one bearing sleeve (24, 24') receiving said pin (22). The pin receives an off-center force (F) that acts at a right angle to the bolt / bearing sleeve unit (20). The at least one bearing sleeve (24, 24') is cylindrical and the pin (22) tapers to the axial end from defined positions. The invention also relates to a geometrically opposite geometry of pin and bearing sleeve.

Description

technical field [0001] The invention relates to an end profile structure (Endprofilierung) for reducing surface pressure on a sliding bearing complementary element (Gleitlagergegenlaufpartnern), comprising a pin and at least one bearing bush receiving the pin, wherein the pin bears a vertical direction Eccentric force acting on the pin-bearing-bush unit. Background technique [0002] Axial units are known which consist of a pin and at least one bearing bush which receives the pin radially, wherein the pin and the bearing bush form complementary plain bearing elements which are assigned to each other. In this case, the pin can absorb a force acting perpendicular to the pin-bearing bush unit (sliding bearing), which acts on the pin centrally or eccentrically. [0003] In particular in commercially available belt tensioning systems, a fastening arrangement consisting of a pin-bearing bush unit of this type is common. Used in belt tensioning systems such as control engines or ...
