The purpose of this utility model provides a kind of pendulum roll-type deceleration machinery, it have simple in structure, volume is little, in light weight, cost is low, stable working, noise is little, load is big, durable, life-span long, big, the energy-efficient characteristic of reduction speed ratio scope, be particularly suitable for being contained in making pendulum roll-type decelerator in the motor.
It is mechanical that the utility model is achieved in that a kind of pendulum roll-type slows down, it is characterized in that having housing, be fixed with internal gear on the housing, the axis place of internal gear is provided with a bent axle, be connected on the housing by bearing, two returnnings are arranged on the bent axle, two returnnings are equipped with the balance planetary external gear of active planetary pinion and this gear respectively by bearing, two gears mesh with the planetary transmission of internal gear respectively, the axis of internal gear is provided with an output shaft, output shaft is connected on the housing by bearing, output shaft with initiatively be connected by a positive heart Hooks coupling universal coupling between planetary external gear.
The structure of above-mentioned positive heart Hooks coupling universal coupling can be: have coupling lever, coupling lever and output shaft or initiatively the center planetary gear between centers have following structure: the end of a part is provided with a recessed sphere and arc-plane formula keyway, the end of another part also is provided with a recessed sphere and arc-plane formula keyway, plane, above-mentioned two arc keyway places is orthogonal, two part middle parts are provided with a spheroid, two arc keys of orthogonal intersection are housed on it, be slidingly matched with the arc keyway on 2 parts, two part ends are provided with the transposition vacancy, i.e. the transposition space.
The structure of above-mentioned positive heart Hooks coupling universal coupling can also be: have a coupling lever, coupling lever and output shaft or active planetary pinion jack shaft are to having following structure: the end of a part has a recessed sphere and keyway, be fixed with dull and stereotyped key in the keyway, the end of another part has the protruding sphere that is slidingly matched with above-mentioned concave spherical surface, and is provided with the spacing rotation keyway that cooperates with dull and stereotyped key.
The similar cross chain coupling of working principle of positive heart Hooks coupling universal coupling, different with cross-garnet butt coupling in the past is that this coupling axially is loose connection, does not promptly have axial coupling member.This structural type compactness (axially), volume reduce, wearing and tearing reduce, noise lowers, and assembling is simple.Owing to be the concavo-convex connection of sphere, guaranteed each sphere centre always on axis (the positive heart), in high speed torque transmits, demonstrate the advantage of high lubricating property, high-wear resistance, high pulling torque transmission performance simultaneously.
In order further to reduce the impact of returnning bearing, improve its life-span, preferably be provided with the elastic sleeve that cooperates with the returnning bearing.For example, the outer ring set of nylon, nylon inner ring sleeve, the outer ring set of rubber, rubber inner ring sleeve etc.
The input shaft of above-mentioned deceleration machinery and the output shaft of motor are one, and the shell of speed reducer also is connected as a single entity with the shell of motor, can make the decelerator of premium properties.Its volume is very little, and is in light weight, and it is convenient to use, and the life-span is long.
Be fixed on the support as the output shaft with above-mentioned reducing motor, speed reducer and motor housing are drum-type structure, can be made into motorized pulleys.Its volume is little, and it is convenient to use.
Characteristics of the present utility model are: simple in structure, volume is little, in light weight, cost is low, stable working, noise is low, the life-span is long, energy-efficient, the reduction speed ratio scope is big, transmitting torque is big, with its reducing motor of making, have volume little, use convenient, flexibly, advantage of wide range of application.
