Embodiment 1

[0087] like figure 2 Shown is the radial sliding-cylindrical surface sliding fixed movable support pin, the movable support tail 210 is a fixed upright wall 211 with the cylinder as the top surface, and the generatrix of the cylinder is parallel to the main shaft axis of the movable support, wherein the fixed vertical Anti-falling walls or reinforcing ribs can also be added on both sides of the wall 211 . The fixed upright wall 211 and its reinforcing ribs are fixed on the movable support base 212, or are integrated with the movable support base 212. During work, the cylindrical surface is in sliding contact with the track surface 10, and the cylindrical surface is fixed relative to the movable support bottom 212.

Embodiment 2

[0089] like image 3 and Figure 4 Shown are the radial sliding-cylindrical rolling fixed support spring pin and the radial fixed support side bearing rolling-cylindrical rolling fixed support spring pin respectively. The dynamic support tail 210 of this type of spring pin is composed of a top bearing 4, Two top bearing pedestals 5 and a top bearing shaft 6 are formed. The outer surface of the top bearing 4 is a cylindrical surface, the top bearing shaft 6 is fixed, and the top bearing shaft frame 5 is fixed on the bottom 212 of the movable support or is integrated with the bottom 212 of the movable support. The generatrix of the outer cylindrical surface of the top bearing 4 is parallel to the main shaft axis of the bullet pin. During work, the cylindrical surface of the top bearing 4 is in rolling contact with the track surface 10, and is fixed relative to the bottom 212 of the movable support.

Embodiment 3

[0091] like Figure 5 and Image 6 Shown are a single top bearing moving bracket and a composite jacking bearing moving bracket respectively. The moving bracket tail 210 of this type of moving bracket 21 is composed of a top bearing 4 , two top bearing shaft frames 5 and a top bearing shaft 6 . The top bearing shaft 6 is fixed, the axis of the top bearing shaft 6 is parallel to the axis of the main shaft, and the top bearing shaft frame 5 is fixed on the movable support bottom 212 or integrated with the movable support bottom 212, which is parallel and symmetrical to the spring needle 2 Two upright walls passing through the center line of the compression spring 22 and perpendicular to the plane (the first symmetry plane of the spring pin) of the axis of the main shaft. The top bearing pedestal 5 can also have two upright walls that are parallel and symmetrical to the plane (the second symmetry plane of the pin) that the pin 2 passes through the center line of the clip spring ...

Abstract

The invention discloses a torque aspirator based on a spring needle mechanism, which comprises: a track, the track surface of which has a rotationally symmetrical axis in geometric configuration; the track surface is a cylindrical surface or other curved surface formed by rotating with a variable diameter; the spring needle , which includes a fixed bracket, a moving bracket and a pressure spring; the bracket body of the moving bracket and the fixed bracket are embedded in the head, and the compression spring is clamped by the bottom of the moving bracket and the fixed bracket, so as to form a single moving pair or a combination of A moving pair with a certain angle of rotation; the tail of the moving bracket constitutes the tip of the spring needle, and the needle tip of the spring needle at the end of the tip touches the track surface and moves along the track surface. The geometry of the spring needle tip matches the geometry of the track surface ; Wherein, one of the track and the spring needle is fixed on the torque suction and discharge shaft in a manner that follows the torque suction and discharge shaft, and the other is fixed. Through the cooperation of the spring pin and the track surface, it realizes the expansion and contraction of the spring pin driven by the compression spring to solve the instantaneous contradiction between power supply and load demand, that is, it endows the torque transmission with the ability to cut peaks and fill valleys as needed.

Description

technical field [0001] The invention relates to the technical field of mechanical energy saving, in particular to a torque aspirator based on a pin mechanism. Background technique [0002] Torque (or torque) transmission is one of the basic forms of mechanical power transmission, and power, load and shaft are the three basic elements of torque transmission. Generally speaking, power and load have their own intrinsic torsional characteristics, but their intrinsic torsional characteristics often do not match, resulting in mixed torque transmission, accompanied by the reduction of the power and load's own energy conversion efficiency, torsional shock , torsional energy transfer loss, shortened device life and reduced reliability. [0003] Rotating shaft torsion power transmission devices have been found in every corner of production and life in today's society, but due to the common difference in torque characteristics between power and load, it is difficult for power and load...
