Description
Technical field
The utility model relates to a kind of retarder, particularly relates to robot retarder.
Background technique
Robot retarder (RV speed reducer) is generally made up of the prime of a planet-gear speed reducer and the rear class of a cycloidal planetary gear speed reducer, its structure set is compact, velocity ratio is large and have auto-lock function is under certain condition integrated, and is one of conventional speed reducer.
Below Liang Zhong robot of the prior art retarder is briefly described: see Fig. 1, the first robot retarder, columniform outer needle roller portion 12 is arranged on gear-box (shell) 11, columniform interior needle roller portion 13 is arranged on planet fluted disc 14, when inputting shaft (input shaft) 18 turns round in a clockwise direction, eccentric bushing 17 is driven also to do revolution clockwise, through ball bearing 17, anticlockwise eccentric operating made by planet fluted disc 14, interior needle roller portion 16 will with the anticlockwise revolution of planet fluted disc 14, while interior needle roller portion 13 is with the revolution of planet fluted disc 14 inhour, because of the engagement driving in inside and outside needle roller portion 13, inside and outside needle roller portion 13 will be made, clockwise rotation is done at 12 Ge Raoqi centers, to exert oneself the passing of pivot pin (axle) 15 along with planet fluted disc 14, to revolve round the sun with anticlockwise direction, the force-output shaft linked with pivot pin 15 of exerting oneself also can do the rotation in anticlockwise direction.Then introduce the second robot retarder, see Fig. 2, the rotation of input shaft is delivered to spur gear 22 from input gear, slows down by gear ratio, and this is the first reduction part.Spur gear 22 is connected with crankshaft portion 23, becomes the input of the second reduction part.In the eccentric part in crankshaft portion 23, by rolling bearing, RV gear is installed.In addition, the only pin tooth of more than the RV number of gears one inside housing department 21, arranges with equal tooth pitch.As set casing portion 21 rotates spur gear 22, then RV gear also carries out eccentric motion due to the eccentric motion in crankshaft portion 23.If now crankshaft rotation one week, then RV gear will rotate a tooth along the direction contrary with crankshaft portion 23, and this rotates the axle being output to the 2nd reduction part.First and second kind of robot speed reducer concrete structure can with reference to prior art.It is higher to there is cost in above-mentioned robot retarder, complex process, the problem that noise is larger.
Model utility content
The purpose of this utility model is exactly to solve the problem, and provides a kind of robot retarder, and object is robot retarder cost is reduced, and reduces noise and difficulty of processing.
To achieve these goals, the utility model adopts following technological scheme: a kind of robot retarder, there is shell, the periphery circumference of described enclosure arranges some outer needle rollers, in described shell, cycloid wheel is set, in the middle part of described cycloid wheel, central gear is set, described central gear is arranged on the input shaft that is installed in shell, in described cycloid wheel, circumference arranges three planetary pinions, each planetary pinion is arranged on corresponding crankshaft, described crankshaft is installed in the enclosure, rotate in order to drive cycloid wheel, each planetary pinion all engages with central gear, described cycloid wheel is positioned between two adjacent planetary pinions and arranges axle, described cycloid wheel periphery circumference arranges some interior needle rollers, described outer needle roller engages with described interior needle roller,
During work, power is passed to planetary pinion by central gear and realizes first order deceleration by input shaft, and transmission of power to cycloid wheel is realized the second level by crankshaft and slows down by planetary pinion, and is outputed power by axle.
Preferably: described input shaft and crankshaft surface are all coated with diamond coatings.
Compared with prior art, the utility model has following beneficial effect: robot retarder cost is lower than external cost, improvement after-processing technology can complete and be not more than 1 arc point precision, the machine Man's Demands in each field can be met, simultaneously, robot retarder noise after improvement reduces greatly, and production difficulty reduces.
