Abstract

The invention relates to the field of transmission devices mainly comprising teeth or friction pieces, connecting rods or levers and cams or at least comprising two elements in the three types, in particular to a stepless speed change device capable of automatically adjusting a motion state and an application method thereof. The stepless speed change device comprises a driving shaft (1) and a driven shaft (2), and is characterized by further comprising a transmission wheel (3) and a bracket (6); the driving shaft (1) includes a driving shaft body (11) and a driving transmission surface (12); the driven shaft (2) includes a driven shaft body (21) and a driven transmission surface (22); the bracket (6) coats the driven shaft (2); and at least one pair of transmission wheels (3) is arranged between the driving shaft (1) and the driven shaft (2). The application method of the stepless speed change device capable of automatically adjusting the motion state is characterized by comprising transmission and adjustment. The stepless speed change device is simple in structure, convenient for use, capable of automatically adjusting the speed and wide in application range.

Description

technical field [0001] The invention relates to the field of transmission mainly including teeth or friction parts, connecting rods or levers, cams, or at least two elements of these three types, specifically a continuously variable transmission device that can automatically adjust the motion state and How to use it. Background technique [0002] The Chinese patent with the publication number 102056697A disclosed a "circular saw" on May 11, 2011, which includes a transmission mechanism of the prior art. The technical solution disclosed in the patent is that the speed change mechanism of the power tool has parallel The first and second rotating shafts and the first gear train and the second gear train having different transmission ratios are arranged, and the first gear train and the second gear train respectively have a gear for meshing with each other and for connecting the first rotating shaft. Torque is transmitted to the driving gear and the driven gear of the second ro...
