Detailed Description

The invention is further described below with reference to the accompanying drawings:

as shown in fig. 1, in the figure: 1. output shaft, 2, bearing II, 3, driver plate, 4, key, 5, gear shaft, 6, slider, 7, round pin axle, 8, screw II, 9, bearing I, 10, fixing base I, 11, screw I, 12, retaining ring, 13, fixing base II, 14, ring flange, 15, box extension board.

The automatic transmission device comprises an input shaft, an output shaft and a box body support plate, wherein the input shaft and the output shaft are both arranged on the box body support plate, a pin shaft is arranged on the end face of the input shaft, one end of the output shaft is provided with a drive plate which rotates along the axis of the output shaft, a sliding groove with a sliding block therein is formed in the drive plate, one end of the pin shaft is in contact with the sliding block, the central line of the output shaft deviates from the central line of the input shaft, the input shaft is a gear shaft, the gear shaft is arranged on a fixed seat I, the fixed seat I is arranged on the box body support plate through a fixed seat II, the gear shaft is arranged on the fixed seat I through a bearing I and a check.

The gear shaft of the invention is connected with the power of the main drive to provide the power of the drive, the gear shaft is installed on a fixed seat I through a bearing I, a retainer ring and a screw I, and the fixed seat I is installed and fixed on a box body support plate through a fixed seat II and a screw; the end face of the gear shaft is provided with a fixed pin shaft, the pin shaft toggles the dial plate to rotate through a sliding block in the dial plate groove, and the dial plate is fixed on the output shaft through a key and a screw II to drive the output shaft to rotate; the output shaft is connected with a flange plate through a bearing, and the flange plate is fixed on the box body support plate through screws. When the gear shaft rotates, the sliding block is shifted through the pin shaft, the sliding block transmits power to the driving plate, the driving plate drives the output shaft to rotate, and the sliding block moves in the driving plate groove while rotating. When the sliding block moves to the maximum distance from the center of the output shaft, the rotating angle in unit time is minimum, and the rotating speed of the output shaft is slowest; when the sliding block moves to the minimum distance from the center of the output shaft, the rotating angle in unit time is the largest, and the rotating speed of the output shaft is the fastest at the moment, so that the rotating speed of the output shaft is changed according to the sine line.

The invention mainly adopts the structure concept that the center line of the power input shaft and the center line of the output shaft deviate a certain distance, the slide block in the output shaft chute is stirred to push the output shaft end to rotate by making a fixed pin shaft at the input end do uniform motion along the center line of the input shaft, and the distance of the slide block in the output shaft chute regularly changes by rotating for a circle, thereby realizing the speed change of the output sine line. The power of the main transmission is transmitted to the gear shaft, and the sliding block in the sliding groove of the driving plate at the end face of the output shaft is stirred by the shaft pin arranged on the end face of the gear shaft to push the output shaft to rotate. The input shaft rotates at a constant speed, and the rotating angles in unit time are the same; for the output shaft, as the central line deviates a certain distance, the rotating angle in unit time changes along with the movement of the sliding block, when the sliding block is at the maximum distance from the center of the output shaft, the rotating angle in unit time is the minimum, the rotating speed is the slowest, and when the sliding block is at the minimum distance from the center of the output shaft, the rotating angle in unit time is the maximum, the rotating speed is the fastest, so that the speed change of the output sine line is realized.
