Combined transmission conversion mechanism

Abstract

The invention relates to a combined transmission conversion mechanism. The mechanism comprises an epicycloidal gear crankshaft. A shaft hole matched with the outer race of an angular contact ball bearing is formed in the epicycloidal gear crankshaft. The angular contact ball bearing is matched with an A segment of a shaft I. A hypocycloidal gear ring is arranged on the left end surface of a combined gear I. An epicycloidal gear is engaged with the hypocycloidal gear ring. The shaft I is connected with a shaft II through the angular contact ball bearing. A C segment on the shaft I is matched with a spline socket. A spline groove matched with a combined gear II is formed in an A segment of the shaft II. The combined gear II is bonded to the combined gear I by sliding on the spline groove ofthe shaft II and the spline socket, and disconnection and connection of the shaft I and the shaft II are achieved; and a spline groove and a retainer ring groove are formed in an A segment of an intermediate shaft, a key groove matched with a cylindrical gear II is formed in a B segment of the intermediate shaft, and by changing the engagement states of the combined gears and cylindrical gears, the bonding state between the combined gears and the power input direction, acceleration or deceleration transmission conversion from first-level to third-level or from third-level to first-level is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a combined transmission conversion mechanism, which is suitable for cutting and combining, decelerating and speeding up the power of three shafts on a straight line. Background technique [0002] With the rapid development of my country's economy, more profound changes have taken place in industries such as automobiles, petroleum, motorcycles, and aerospace. Mechanical transmission, assembly lines, and food packaging all require combined transmission conversion mechanisms. The existing combined transmission conversion mechanisms are bloated. , complex structure, can only realize the unidirectional flow of power, can not realize the two-way flow of power; and the existing combined transmission transformation mechanism can not realize the power cutting and combining, deceleration or speed-up of three axes on a straight line.

[0002] With the rapid development of my country's economy, more profound changes have taken place in industries such as automobiles, petroleum, motorcycles, and aerospace. Mechanical transmission, assembly lines, and food packaging all require combined transmission conversion mechanisms. The existing combined transmission conversion mechanisms are bloated. , The structure is complicated, and only one-way flow of power can be realized, and two-way flow of power cannot be realized; and the existing combined transmission conversion mechanism cannot realize the power cutting and combination, deceleration or speed-up of three axes on a straight line
