Abstract
The utility model relates to a speed reducer. The utility model provides a nest rolling output mechanism for planetary speed reducers. The machine utilizes a rolling element to filter out the revolution motion of a planetary transmission, and transmit the spinning motion to an output shaft. The utility model has the advantages of compact structure and small volume, replaces sliding friction by rolling friction, therefore, the utility model also has the advantages of high transmission efficiency, etc.
Description
The utility model relates to a kind of speed reducer, particularly relates to a kind of output mechanism of fewer differential teeth planetary decelerator.
In the prior art, various few tooth differential planetary speed reducers comprise cycloidal-pin wheel planetary speed reducer and involute planetary gear speed reducer, its output mechanism mainly contains following several: 1. pin axle type output mechanism, 2. crosshead shoe output mechanism, 3. floating disc type output mechanism, 4. zero teeth difference type output mechanism.In addition, second pair of gear pair of NN type planetary gear speed reducing mechanism also uses as output mechanism when slowing down.More than various structures its pluses and minuses are all arranged.The high axial dimension of pin axle type output mechanism transmission efficiency is compact, but requirement on machining accuracy height, because bearing pin is equivalent to overhang, for guaranteeing necessary strength, pin diameter must be enough big, on planetary pinion, must occupy sizable position, the radial dimension of speed reducer is strengthened, then reduce relatively in the space that bearing occupies, and has reduced bearing intensity, and the crosshead shoe output mechanism is fairly simple, be easy to processing, but transmission efficiency is lower, and axial dimension is bigger, and is general comparatively suitable under the situation of small-power intermittent working.Floating type output mechanism efficient is higher, but no matter adopts rolling sleeve type structure or bearing structure, and its size is all bigger.Advantages such as NN type planetary speed reducer structure is similar with zero tooth difference speed reducer, has processing simple and easy, and speed ratio is big, and radial dimension is little, but axial dimension is difficult to reduce, and therefore the problem that occurs under little speed ratio situation generally is used for the large speed ratio transmission more.In addition, more than all driving mechanisms a common shortcoming is all arranged, promptly reduce volume and eliminate sliding friction and be difficult to take into account simultaneously, therefore to realize quite difficulty of volume is little, power is big, efficient is high speed reducer.
The purpose of this utility model provide a kind of axially and radial dimension all very little, simple and compact for structure, and, thus, make planetary speed reducer reach that volume is little, efficient is high, noise is low, technique effect stably turns round to roll as the planetary speed reducer output mechanism of the kind of drive substantially.
The utility model is finished like this: at first arrange two above rolling elements 5 between planetary pinion and motor output shaft 6 end face gardens dish, its number is according to speed reducer size and requirement of strength decision, these rolling elements 5 can be distributed on the concentric garden, also can not be distributed on the concentric garden.The position corresponding on the dish of planetary pinion 3 and motor output shaft 6 end face gardens with rolling element 5, make the garden nest shape shallow hole 1 that number equates with rolling element 5 numbers, garden nest diameter is equivalent to the throw of eccentric that rolling element 5 diameters add upper planetary gear 3, and its edge section shape and rolling element 5 adapt.Rolling element 5 rolls around nest edge, garden during running, and the revolution motion of planetary pinion 3 is filtered out, and its spinning motion is transferred to output shaft 6.
The utility model also is divided into planetary pinion 3 two planetary pinions of equity, these two planetary pinions respectively are installed on two opposite eccentric bushings 2 of eccentric direction, between two planetary pinions, place plural rolling element 5, its number is also decided according to speed reducer size and requirement of strength, these rolling elements can be distributed on the concentric garden, also can be distributed on other appropriate location, on the two-wheeled position corresponding with rolling element, make the same number of garden of number and rolling element nest shape and cheat 28, its diameter equals the rolling element diameter and adds the twice throw of eccentric, and its edge section shape and rolling element adapt.Rolling element rolls along nest edge, garden during moving the commentaries on classics.The centrifugal force that two-wheeled produced is cancelled out each other thus, does not therefore need balance iron, has reduced the axial dimension of speed reducer.
Above-mentioned rolling element can be made into the drum shaped body that garden ball, short garden post, garden sheet or other any curve are rotarily formed.Above-mentioned garden nest shape shallow hole one and two also can be made into the garden ring raceway, and its external diameter is identical with garden nest diameter, and raceway section shape and rolling element 5 adapt.
In order to make its compact structure, planet wheel 3 and eccentric bushing 2 directly can be contained on 1 in the motor, make motor 1 flange plate as the speed reducer bonnet simultaneously, thereby the speed reducer volume is reduced to as far as possible little degree.
The utility model compared with prior art has the following advantages:
(1). compact structure, volume is little;
(2). running is steadily;
(3). the transmission efficiency height.

Eccentric bushing 2 of the present utility model directly is contained on 1 on the motor, and the eccentric direction of two eccentric bushings is opposite.Planetary pinion 4 is meshed with gear ring 4, transmission all can be selected as the case may be with steel ball 5 its numbers, diameter and position, output shaft 6 end faces have the garden dish, and the diameter of garden nest shape shallow hole 1 equals the garden bulb diameter and adds throw of eccentric, and the diameter on nest shape shallow hole ground, garden 8 equals the garden bulb diameter and adds the twice throw of eccentric.The utility model can be used for few tooth differential Gear Planet Transmission of cycloid in planet transmission, involute planetary transmission and other any profile of tooth as output mechanism.Reach a compact structure, good effects such as volume is little, running is steady, transmission efficiency height.
