Problems solved by technology

[0004] 2) No overload protection function, the transmission process is fast, fast, and too rigid;
[0005] 3) When the gear cutting accuracy is required to be high or have a special tooth shape, high-precision machine tools, special tools and measuring instruments are required to ensure that the manufacturing process is complicated and the cost is high;
[0006] 4) Gears are easily worn under friction, which can easily lead to slipping
[0007] At the same time, in some fields with small power transmission, flexible starting and small starting torque are required; gear transmission often has the above limitations, so a transmission structure with simple structure, more labor-saving, lower cost and more flexible is required

Abstract

The invention provides a variable force transmission mechanism, and belongs to the field of mechanical transmission. Comprising a first crankshaft rod, a second crankshaft rod, a connecting structure, a base body frame and a supporting frame. The base body frame comprises two outer supports which are oppositely arranged in parallel. Each of the first crankshaft rod and the second crankshaft rod is formed by sequentially connecting a plurality of bent structure rods end to end, and the first crankshaft rod and the second crankshaft rod penetrate through the through holes in the upper ends of the supporting frames and are rotationally connected with the supporting frames; the head end and the tail end of the first crankshaft rod are connected to the two opposite outer supports in a rolling mode correspondingly, and the multiple connecting structures stretch across the position between the first crankshaft rod and the second crankshaft rod at intervals. In the whole transmission mechanism, the multiple connecting structures are connected for transmission, it is guaranteed that power transmission is stable and flexible, and the multiple bent structure rods are evenly arranged around the axis of the crankshaft rod at an angle; the overall structure is simple, installation is convenient, high-precision technical support is not needed, cost is lower, and more flexible transmission can be achieved.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a variable force transmission mechanism. Background technique [0002] At present, in the field of machinery, gear transmission is the most widely used and is more suitable for transmission between large powers. It can be used to transmit motion and power between two shafts that are not far from each other. In the process of power transmission, gear transmission will have the following defects : [0003] 1) Vibration, impact and noise during operation, and generate dynamic load; [0004] 2) No overload protection function, the transmission process is fast, fast, and too rigid; [0005] 3) When the gear cutting accuracy is required to be high or the gear has a special tooth shape, high-precision machine tools, special tools and measuring instruments are required to ensure that the manufacturing process is complicated and the cost is high; [0006] 4) The gears are easily ...
