Three-facet step turnover transmission mechanism

Abstract

A three-facet step turnover transmission mechanism with uniform step angles and good turnover effect belongs to three-facet transmission mechanisms. The transmission mechanism comprises a drive shaftand a driven shaft, the drive shaft is connected with step wheels in a transmission way, the driven shaft is connected with wobbler wheels in a transmission way, the step wheels and the wobbler wheelsare orthogonally locked, the step wheels are provided with gear ports, the drive shaft is a splined shaft and provided with external splines, the step wheels are provided with internal splines, and the drive shaft is in spline coupling with the step wheels, the included angle between a connecting line of the center of the gear ports of the step wheels and the drive shaft and the horizontal planeis a step angle, the drive shaft is coupled with a plurality of step wheels, the degrees of two adjacent step angles are different, and the degrees progressively increase or decrease gradually. In thethree-facet step turnover transmission mechanism, two components which are the current tubular plastic part and the gear wheels are improved as an integral structure, gear port directions of the stepwheels are different, and have a certain angle difference during the installation; in such a way, the step angles of the step wheels are absolutely uniform, and the turnover effect is aesthetic during rotation without malfunction.

Description

technical field [0001] The invention relates to a three-side turning transmission mechanism, in particular to a three-side turning stepping and turning transmission mechanism. Background technique [0002] When turning over on three sides, each triangular tube is generally turned over gradually one by one. Each stepping wheel (ie, dial) is installed on the transmission shaft in sequence, and there is a "stepping angle" between each stepping wheel and the horizontal plane. , that is, the direction of each stepping wheel shifting tooth is gradually rotated at a certain angle relative to the transmission shaft. The common practice in China is to divide the stepping wheel into two components, that is, the middle part of the wheel can slide freely along the direction of the transmission shaft. The tubular plastic parts and the gears on the outer ring of the wheel are manually screwed to a certain angle and then fixed with self-tapping screws, so that there is a step angle between...

[0002] When turning over on three sides, each triangular tube is generally turned over gradually one by one. Each stepping wheel (ie, dial) is installed on the transmission shaft in sequence, and there is a "stepping angle" between each stepping wheel and the horizontal plane. , that is, the direction of each stepping wheel shifting tooth is gradually rotated at a certain angle relative to the transmission shaft. The common practice in China is to divide the stepping wheel into two components, that is, the middle part of the wheel can slide freely along the direction of the transmission shaft. The tubular plastic parts and the gears on the outer ring of the wheel are manually screwed to a certain angle and then fixed with self-tapping screws, so that there is a step angle between every two adjacent stepping wheels, so as to realize The progressive flipping of the triangular tube, but because it is manually adjusted, the step angle is uneven, the flipping effect is not good, and many quality problems occur
