Description
Technical field
The utility model belongs to the mechanical transmissioning technology field, relates in particular to a kind of pinwheel output needle pendulum Gear Planet Transmission retarder.
Background technique
Tradition cycloidal-pin wheel gearing speed-reducer all has a common weakness: pinwheel is fixed, cycloid wheel cast-over crop rotation planetary motion, an independent output mechanism must be arranged thus, and rotary arm bearing is in planet wheel (cycloid wheel), size is subjected to the restriction of planet wheel, simultaneously because the restriction output mechanism of structure can only adopt cantilever structure, limited quantity as the cycloid wheel of planet wheel, usually can only adopt two cycloid wheel, can't realize the equilibrium problem of moment in the transmission process, the raising of the intensity of simultaneity factor rigidity and each parts all is restricted, thereby has restricted the further raising of complete machine bearing capacity.Other has a kind of ring-plate pin pendulum Gear Planet Transmission retarder, because (ring flat-plate is a nonaxisymmetric structure to the restriction of the physical dimension of ring flat-plate, and weight and rotary inertia are bigger), the inertial force of ring flat-plate can't active balance in transmission process, so in transmission process, can cause bigger vibration and noise, influence using effect; Simultaneously, though adopt the structure of four ring flat-plates to increase the bearing capacity of complete machine, the physical dimension and the weight of retarder also are multiplied.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and a kind of bearing capacity height, transmission efficiency height, pinwheel output needle pendulum Gear Planet Transmission retarder that cost performance is high are provided.
The technological scheme that its technical problem that solves the utility model adopts is: pinwheel output needle pendulum Gear Planet Transmission retarder, mainly comprise pinwheel 1, output disc 2, pin supporting disk spring bearing 3, pin supporting disk 4, input shaft 5, input shaft spring bearing 6, pin 7, roller 8, cycloid wheel 9, gear pin 10, pin gear sleeve 11, casing 12, case lid 13, rotary arm bearing 14, eccentric bushing 15 and needle bearing 16, it is characterized in that, pinwheel 1 output, pin 7 one ends are fixed in pin supporting disk 4, one end is fixed on the case lid 13, the rotation of restriction cycloid wheel 9,9 two one group of cycloid wheel, phase phase difference 180.Cycloid wheel 9 is finished pin pendulum Gear Planet Transmission with pin gear sleeve 11 engagement driving in the process of doing the space translation, pin gear sleeve 11 outputs power to output disc 2 as output shaft by gear pin 10 and pinwheel 1, output disc 2 and pinwheel 1 link by coupling, and are supported in the casing 12 by needle bearing 16.Described cycloid wheel 9 has two groups at least.
The beneficial effects of the utility model are: the bearing capacity of similar retarder complete machine is increased at least be twice, the power of complete machine in transmission process and the balance of moment have been realized simultaneously, give full play to transmission advantages such as the multiple tooth conjugation engagement of pin pendulum Gear Planet Transmission and the hard flank of tooth, obtained bigger bearing capacity and long service live more; Increase the rigidity of system, improved transmission accuracy, reduced the complete machine natural frequency of vibration, improved the antivibration ability; Also increase machine weight as few as possible, the cost performance of retarder is improved.
