Abstract
The invention relates to a planetary reducer with small teeth differences. According to the technical scheme, the planetary reducer with small teeth differences is characterized by comprising a frame and a power input shaft; the power input shaft is rotationally arranged on the frame through a first bearing; two eccentric shaft sections with opposite direction are fixedly arranged on the power input shaft and are provided with gears through a second bearing respectively; the two gears are in the same shape, and the outer portions of the two gears mesh with a same inter gear respectively; the meshing positions of the two gears and the inter gear are located on the corresponding side faces of inter teeth thread of the inter gear; and a plurality of through holes are evenly distributed on the peripheries of the two gears, a positioning pin is arranged in each through hole, a sliding pin sleeve is sleeved on each positioning pin, and the positioning pins rotationally match with the through holes of the gears through the sliding pin sleeves. The novel planetary reducer is reasonable in structure, low in cost and large in output torque.
Description
Technical field
The present invention relates to the big speed reducer of a kind of outputting torsion.
Background technique
At present, the speed reducer kind of various structures is a lot of on the market, and major part all realize to slow down by gear train, and such speed reducer outputting torsion is little, and its usage mode is restricted, also more complicated of internal structure in addition, and cost is than higher, and versatility is poor.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and provides a kind of rational in infrastructure, and cost is low, the novel fewer differential teeth planetary decelerator that outputting torsion is big.
Realize above-mentioned purpose, the present invention adopts following technological scheme: a kind of fewer differential teeth planetary decelerator, it is characterized in that: include frame, power input shaft, power input shaft rotates by clutch shaft bearing and is arranged on the frame, fixedly install the opposite eccentric shaft part of both direction on the input shaft, be provided with gear by second bearing respectively on two eccentric shaft parts, the shape of two gears is identical, the outside of two gears is engaged with same internal gear respectively, two gears and the engagement position of internal gear are positioned at the relative bi-side of groove of internal gear, the periphery of two gears is evenly distributed with a plurality of through holes, is provided with locating stud in each through hole, and locating stud is fixedly installed on the frame, be arranged with the slip guide on the locating stud, locating stud is rotatably assorted by the through hole formation of slip guide and gear.
By adopting such scheme, make speed reducer have simple in structure, volume is little, characteristics such as outputting torsion is big, wherein when can making transfer input shaft moving, two eccentric wheels are enclosed within two gears while active forces on the eccentric wheel on internal gear by arranging, and active force is on two corresponding surfaces of internal gear, reversing greatly of internal gear just increases greatly like this, the running track of using each gear of assurance of locating stud.
The further setting of the present invention is: described internal gear both sides are provided with chimb, be provided with the 3rd bearing between two chimbs and the frame, described two gears periphery through hole arranges equally, be provided with same locating stud between the through hole of two gears its mutual conduction after two eccentric shaft parts shift to install, the two ends of locating stud all are fixed on the frame; Described frame is provided with through hole, and input shaft places this through hole, and input shaft rotates by two clutch shaft bearings of being spaced apart and is arranged on the frame, and two eccentric shaft parts are arranged between two clutch shaft bearings of input shaft and adjacent setting,
By adopting such scheme, be optimize product structure, the basis of performance and ease of use makes, the above-mentioned plan of establishment in addition can make these speed reducer both sides use, and increases its versatility.
Below in conjunction with accompanying drawing the present invention is further described.
