Indexing movable tooth transmission with intermittent motion

Abstract

The invention discloses an indexing movable tooth transmission device with an intermittent motion. A movable tooth frame is arranged in a center wheel, and is a ring formed by connecting multiple movable tooth frame sections by gaskets; through holes are formed in the two sides of each gasket; the two through holes are corresponding to connecting through holes on two adjacent movable tooth frame sections; two adjacent movable tooth frame sections are connected by bolts penetrating through inner and outer gaskets and the connecting through holes; and a push rod movable tooth is arranged on eachpair of gaskets, and comprises a push rod, a baffle plate, a spring, a bearing frame, rolling bearings and a pin shaft. Two rolling bearings of the push rod movable tooth are near an outer arc surface of a wave exciter and an inner arc of the center wheel; a key slot is formed in a center through hole of the wave exciter; grooves, axially recessed, are formed in the outer peripheral surface of the wave exciter; the generatrix of the groove is parallel to the axis of the wave exciter; and two or multiple grooves are symmetrical about a plane crossing through the axis. The indexing movable tooth transmission device with the intermittent motion is stable in transmission; and through the springs on the push rod movable teeth, the impact in the transmission process is reduced, the vibration isreduced, and the service life of the movable tooth transmission mechanism is prolonged.

Description

technical field [0001] The invention relates to movable gear transmissions. Background technique [0002] With the current development of mechanical products in the direction of automation, the status of various automatic machines in mechanical products is becoming more and more prominent. Due to the requirements of the production process, mechanisms are often needed to achieve periodic indexing and indexing actions, and various intermittent mechanisms have gradually entered the industry. Due to its small volume and weight, large transmission ratio, high efficiency, stable operation, low noise and long life, the movable tooth reducer is widely used in ships, vehicles and agricultural machinery. With the research on movable tooth reducer In-depth, the optimization of its structure is becoming more and more important. For example, the patent CN 107166017 A can well realize the problem of anti-backlash in the movable tooth transmission process, but the general structure of the...

Problems solved by technology

Due to its small volume and weight, large transmission ratio, high efficiency, stable operation, low noise and long life, the movable tooth reducer is widely used in ships, vehicles and agricultural machinery. With the research on movable tooth reducer In-depth, the optimization of its structure is becoming more and more important. For example, the patent CN 107166017 A can well realize the problem of anti-backlash in the movable tooth transmission process, but the general structure of the current movable tooth reducer cannot realize its intermittent motion function , cannot be used in mechanisms that require periodic pauses and movements. Currently, other types of intermittent mechanisms, such as intermittent cams, have disadvantages such as insufficient carrying capacity, unstable operation, and loud noise.
