Abstract
A planetary speed reducer with less teeth difference is composed of high-speed axle with eccentric wheel, annular plate with internal gear ring and the matching hole of eccentric wheel, low-speed axle with external gear, and casing. The method is characterized in that: the speed reducer is provided with three high-speed shafts with the same structure and two ring plates with the same structure, two eccentric wheels with opposite eccentric directions are arranged on the high-speed shafts, three eccentric wheel matching holes are radially and uniformly distributed in inner gear rings in the middle of the ring plates, a high-speed shaft connected with a prime motor is parallel to a low-speed shaft connected with a working machine and is rotatably arranged on a box body, an outer gear on the low-speed shaft is meshed with the inner gear rings on the ring plates, and the eccentric wheels on the high-speed shafts are in movable matching with the eccentric wheel matching holes on the ring plates. The utility model discloses simple structure, it is easy to make the assembly, light in weight, with low costs, the dependable performance, long service life is applicable to trade departments such as metallurgy, chemical industry, petroleum, gently spin, medicine, food, machinery, is an ideal mechanical transmission.
Description
" mechanical transmission " magazine the 16th is rolled up 37 pages of the 4th phases and has been put down in writing a kind of K-H three-ring speed reducer, it belongs to planetary speed reducer with small tooth number difference, by the lower velocity shaft (1), two of a band external gear respectively with ring flat-plate (4), (5), (6) and casing (7) formations of three eccentric high speed shafts (2) that are 120 ° of angles of cut and (3), three band ring gears and eccentric wheel matching hole, each parallel configuration, and rotating being installed on the casing, the eccentric wheel matching hole on eccentric wheel on high speed shaft (2), (3) and ring flat-plate (4), (5), (6) movingly.When prime mover drives the high speed shaft rotation, three ring flat-plates are done plane motion under the eccentric wheel on the high speed shaft drives, together in a flash, ring gear on every ring flat-plate has the external gear engagement on a place and the lower velocity shaft, three contact pointss are 120 ° of distributions, ring gear on the ring flat-plate is stirred external tooth crop rotation on the lower velocity shaft with its engagement and is slowed down and rotate, and power is passed to the working machine that connects with lower velocity shaft by lower velocity shaft.
The shortcoming of this retarder is a complex structure, and three eccentric wheel processing difficulties that are 120 ° of angles of cut on the high speed shaft are difficult for assembling.
The purpose of this utility model provides a kind of simple in structure, and processing and assembling is easy to planetary speed reducer with small tooth number difference.
The purpose of this utility model is to realize like this, adopt the identical high speed shaft of the three root architectures ring flat-plate identical with two chip architectures, two eccentric wheels are arranged on the every high speed shaft, two eccentric eccentric directions are opposite, every ring flat-plate has a ring gear, ring gear radially has three eccentric wheel matching holes, three high speed shafts are parallel to each other, and rotating being installed on the casing, eccentric wheel on the high speed shaft and the eccentric wheel matching hole on the ring flat-plate are movingly, lower velocity shaft and rotating is installed in casing on parallel that has external gear with high speed shaft, the ring gear engagement on the external gear on the lower velocity shaft and two ring flat-plates.When the high speed shaft that connects with prime mover rotates, the two rings plate is done plane motion under eccentric drive, ring gear on the ring flat-plate is stirred external tooth crop rotation big retarding on the lower velocity shaft with its engagement than rotating, and by lower velocity shaft power is passed to driven work mechanism.The power of prime mover can also can be imported by three high speed shafts simultaneously by one or two high speed shaft inputs.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is known K-H three-ring speed reducer structural drawing
Fig. 2 is the utility model structural drawing
In Fig. 2,9 and 10 is the identical ring flat-plates of two chip architectures, at the ring flat-plate center ring gear 11 is arranged, at three eccentric wheel matching holes of ring gear radial equipartition 12,13,14, three high speed shafts 15,16,17 have 18,19, two eccentric eccentric directions of two eccentric wheels opposite on the every high speed shaft, a lower velocity shaft 20 has external gear 21 on the lower velocity shaft.Three high speed shafts are parallel with lower velocity shaft, and rotating being installed on the casing, and casing does not draw in the drawings; Eccentric wheel matching hole on the ring flat-plate and the eccentric wheel on the high speed shaft are movingly; Moment is meshed in external gear on the lower velocity shaft and the engagement of the ring gear on the ring flat-plate, and the contact points on two ring flat-plates is 180 ° of distributions.During work, prime mover is imported power by high speed shaft.When high speed shaft rotated under prime mover drives, the eccentric wheel on the high speed shaft drove ring flat-plate and does plane motion, and the external gear that the ring gear on the ring flat-plate is stirred on the lower velocity shaft rotates, and rotated thereby drive the working machine that connects with lower velocity shaft.High speed shaft in the utility model also can turn bent axle with the hyperbolic of axis in same plane and replace.
Because the utility model high speed axle has only two eccentric wheels, the two rings plate, and also two eccentric eccentric directions are opposite, therefore make assembling easily, and simple in structure, cost is low.
