Description

A kind of planetary reducer

Technical field

It the utility model is related to mechanical speed change drive technology field, especially a kind of planetary reducer.

Background technology

Planetary gear reducer belongs to K-H-V type Gear Planet Transmissions, is a kind of new mechanical driving device.The biography Dynamic device is by centre wheel（Centre wheel K）, planet carrier（That is eccentric shaft H）Formed with special output mechanism V, it has single-stage driving Than big, compact-sized, small, light weight, the features such as easy to process, reliable, service life is long, transmission efficiency, application In industries such as oil, chemical industry, agricultural machinery, light industry mine, building machineries.Many mechanical transmissioning technology published books fill such transmission Put and be also elaborated, usually, for its transmission mechanism, be broadly divided into：It is pin type, floating disc, slide block type, few Tooth differential, zero tooth differential, bellows-type, double crank type and the single groove of single pin are sliding.These output mechanisms are because of complicated, system Make that difficult, easy to wear, gap is big, cause output accuracy low, return difference is big, it is impossible to applied to more demanding occasion.

Utility model content

In view of the above-mentioned drawbacks of the prior art, problem to be solved in the utility model there is provided a kind of planet tooth Wheel decelerator, it is not only simple in structure, and processes and assembles easily, meanwhile, output accuracy is also greatly improved, reduces return difference, even It may also reach up gapless output.

In order to solve the above-mentioned technical problem.A kind of planetary reducer of the utility model, including output device, it is special Sign be the output device include two end faces, a floating ring being arranged between two end faces and one end quartering with Floating ring connection, the other end intersect four linking arms being connected with two end faces.The transmitting device, which has, to be made to justify around axis All translational motions, the characteristic of not autorotation.

Planetary reducer includes casing, planetary gear, centre wheel, eccentric bushing, transmitting device and output shaft.Using upper State the planetary reducer of output device, during work, eccentric bushing, which rotates, drives the planetary gear with centre wheel internal messing to put down Face is moved, i.e., planetary gear makees circumference translational motion, and the movement for making to turn round around own axes around centre wheel axis, if centre wheel It is fixed on output shaft, output device connection planetary gear and casing, at this moment, planetary gear cannot rotate, and centre wheel can rotate, Then output device compensates planetary circumference translational motion, and rotary motion is passed to centre wheel, is finally exported by output shaft； If centre wheel is fixed on casing, output device connection planetary gear and output shaft, at this moment, planetary gear can rotate, centre wheel It cannot rotate, then output device compensates planetary circumference translational motion, rotary motion is passed to output shaft, by output shaft Output.

A kind of preferred solution as a kind of planetary reducer of the utility model：Output device include two end faces, The floating ring and one end quartering being arranged between two end faces are connected with floating ring, the other end intersects and two end faces Four linking arms of connection, two end faces can be an entirety with external part, have among two end faces and floating ring One through hole passes through, and the central shaft of two end faces, floating ring and through hole is same axis, through two end faces and the through hole of floating ring Shape be square, two end faces, floating ring and linking arm have connection end, for two end faces and linking arm and is connected Connection between arm and floating ring, linking arm are affixed elastic components.

As a kind of another preferred solution of planetary reducer of the utility model, difference is：Through two The shape of the through hole of a end face and floating ring is circular shape, and the linking arm is the rigid member being hinged.

In short, using the planetary reducer of above-mentioned utility model, planet tooth in planetary reducer can compensate for The circumference translational motion of wheel, planetary rotary motion high accuracy, gapless are exported.
