Abstract
The utility model belongs to a speed reducer for machine driving, comprising a rotating arm, an output axis, an inner ring gear, an outer gear, a shell and a pin axis. The utility model is characterized in that the inner ring gear is arranged in the shell; the inner ring gear is meshed with the outer gear; an eccentric wheel is arranged on the inner ring gear concentrically; the eccentric wheel is fixedly connected with the rotating arm; a plurality of pin holes are arranged on the inner ring gear; the pin axis passes through the pin holes to fix on the shell, wherein, and the diameter of the pin hole is larger than that of the pin axis; the outer gear is fixedly connected with the output axis; a supporting bearing is arranged on the shell arranged on the both ends of the rotating arm and the output axis; the rotating arm is collinear with the output axis. The utility model has the advantages that the output and the input as dead axes are collinear; an output mechanism V is unnecessary; the structures of the input and output axes are not cantilever structures; the stress of each component is even; the axial dimension is reduced; the stress of the pin axis is little, and the pin axis is not easy to break off; the stress of the bearing of the rotating arm is also little, and the dead position does not exist; the service life is long.
Description
The utility model belongs to a kind of mechanical transmission retarder.
Existing coaxial input output fewer differential teeth planetary speed reducer mostly is the K-H-V type speed reducer greatly, and its structure is the planetary gear train of being made up of central gear K, pivoted arm H and output mechanism V, not only rotation but also revolve round the sun of planet wheel in its operation process.Because planet wheel and input shaft disalignment and revolution is arranged, so need output mechanism, and output shaft must make cantilever structure, so the member stress inequality, rotary arm bearing, output mechanism damage easily, and axial dimension is big.
Goal of the invention of the present utility model is to provide a kind of input output coaxial and need not the planetary reducer of output mechanism.
The utility model is realized by following scheme: it comprises pivoted arm, output shaft, ring gear, external gear, shell and bearing pin, it is characterized in that being provided with in the shell ring gear, ring gear and external gear engagement, one eccentric wheel is set on ring gear with one heart, eccentric wheel and pivoted arm are affixed, several pin-and-holes are set on ring gear, bearing pin passes pin-and-hole and is fixed on the shell, wherein the pin-and-hole diameter is greater than bearing pin, external gear and output shaft are affixed, on the shell at pivoted arm and output shaft two ends, spring bearing is set, pivoted arm and output shaft conllinear.
The utility model input output are the dead axle conllinear, the V of no-output mechanism, input, output shaft are non-cantilever structure, each member stress is even, reduced axial dimension, because bearing pin and shell are one, and are distributed on the bigger circumference of radius, when bearing identical moment of face, bearing pin is stressed littler than K-H-V type, frangibility not, rotary arm bearing is stressed also little, and the life-span is long; Ring gear both can be designed to monolithic, also can be multi-disc, and did not have the dead center position.
Fig. 1 is the structural representation of retarder.
Fig. 2 is the left view of retarder.
Fig. 3 is the ring gear structural representation.
As shown in Figure 1, 2, 3, retarder comprises pivoted arm 8, output shaft 6, ring gear 2, external gear 5, shell 1, spring bearing 7 and bearing pin 4, ring gear 2 is set in the shell 1, ring gear 2 and external gear 5 engagements are provided with an eccentric wheel 9 with one heart on ring gear 2, several pin-and-holes 3 are set on ring gear 2, bearing pin 4 passes pin-and-hole 3 and is fixed on the shell 1, wherein pin-and-hole 3 diameters are provided with spring bearing 7 greater than bearing pin 4 at pivoted arm 8 and output shaft 6 two ends, and pivoted arm 8 and output shaft 6 conllinear.Pivoted arm 8 is affixed with eccentric wheel 9, and output shaft 6 is affixed with external gear 5.Squarely can be done by ring gear 2 tail protrusion places, also can do circularly, and a side is open-minded, and spring bearing 7 and shell 1 are fixed together.During retarder work, pivoted arm 8 drives eccentric wheel 9 and rotates, and ring gear 2 is being done translation under the drive of eccentric wheel 9 and under the constraint of bearing pin 4, and drives output shaft 6 with external gear 5 engagements, realizes the output of motion and power.
Its velocity ratio is:
I=W
Input/ W
Output=-Z
Outward/ (Z
