Embodiment 1

[0013] Embodiment 1: a dynamic intermittent operation reducer, including a reducer input shaft 14, a first-stage reduction transmission gear 4 and a second-stage reduction transmission gear shaft 12, the first-stage reduction transmission large gear 4 is in phase with the reducer input shaft 14 Mesh, and through the rolling bearing 1 empty sleeve on the second-stage reduction transmission gear shaft 12; between the first-stage reduction transmission large gear 4 and the second-stage reduction transmission gear shaft 12, there is a device that can dynamically control the combination of the two. and disengaged combination clutch / brake 13. The rim end of the combined clutch / brake 13 is fixedly connected to the first-stage reduction transmission large gear 4 through the connecting screw 2 and the positioning pin 3; while the hub end is connected to the second-stage reduction transmission gear shaft 12 through the flat key 11, and the second-stage The reduction transmission bull ge...

Embodiment 2

[0017] Embodiment 2: The friction disk of the hydraulically driven combined clutch / brake 13 in the present invention must work under the "wet" cooling state, and the working fluid is hydraulic oil; the lubricating oil of the gear and the bearing is gear oil, in order to avoid both For mixing, the present invention sets an isolation band on the periphery of the combination clutch / brake 13.

[0018] The advantages of the present invention are as follows: firstly, the structure is compact and the appearance is beautiful; secondly, the input shaft will always be in a rotating state; thirdly, the combination clutch / brake driven by hydraulic pressure is used, which works smoothly and reliably without hard impact; fourthly, it can be realized conveniently Automatic control of intermittent operation; Fifth, a wide range of applications and a broad market prospect.

Abstract

A vibration absorber of dynamically intermittent-operated type is prepared as engaging the first stage of reduction driving large gear with input shaft of reduction gear and free-jacketing it to the second stage of reduction driving gear shaft through rolling bearing, setting clutch / brake enabling to control separation and combination of the two between said large gear and said gear shaft, driving second stage of driving large gear and output shaft to be operated when clutch frictional disc is contacted and cutting off driving chain of the second stage gear when clutch frictional disc is released.

Description

technical field [0001] The invention relates to a general mechanical transmission device, in particular to a dynamic intermittent operation reducer, which is used for reduction ratio movement and power transmission. Background technique [0002] The characteristics of the existing gear reducer are: after its input shaft is connected to a power source (such as an electric motor, an internal combustion engine), through deceleration transmission, the output shaft is continuously operated at a constant speed, and the power is transmitted to the working machine. If the output shaft of the reducer is required to operate intermittently, there are usually two methods: one is to cut off and connect the power source regularly, and the other is to add a clutch between the power source and the input shaft of the reducer. Its shortcoming is that the former must frequently stop and start the power source, causing adverse effects on the power machinery; the latter increases the external tr...
