TH45968B - Tension adjuster - Google Patents

Abstract

DC60, the first, inner shaft part 3 and outer second shaft part 4 are screwed together by screws 8 and 10 and spring 6 that press the first axle part 1 to rotate in a set direction. The presets are encased in the frame 2, the second shaft part 4 is inhibited from turning. This causes the rotary pressure of the compression spring 6 to be converted to the force that drives the second shaft part 4, the first shaft part 3 rotates while the ends follow. Its axis is in direct or indirect contact with frame 2 and frictional part 6 causing torque. The friction between itself and the first shaft part 3 is arranged in such a way that it touches the first shaft part 3, the elastic part 7 is arranged outside the second shaft part 4 along the radial part. Flexible 7 presses the friction element 6 to touch the first axle part 3 stabilizes the drive of the second axle part 4. To provide a structure for more stable driving of the second shaft segment. The tensioner, wherein, is used for the new high-power engine, inside the first shaft part 3, and the outer part of the second shaft 4 screwed in. Together by screw 8 and 10 and spring 6 pressing the part of the first shaft 1 to rotate in the set direction Before the advance is encased in the frame 2 parts of the second shaft 4 are limited to rotation by the effect of the compression spring of the compression spring 6 is converted to the force that drives the second shaft 4 parts. Of the first shaft 3 rotates while the ends of its axis are in direct and indirect contact with the structure 2 and Frictional part 6 that creates friction between itself and the first shaft part 3 is positioned in contact with the part of the first shaft 3, the retractable part 7 is Is arranged radially Outside the part of the second shaft 4 the retractable part 7 presses the friction part 5 to touch the part. Of the first shaft 3, with the effect of the thrust of the parts of the second shaft 4 is stabilized
