Abstract
The utility model relates to a ringlike decelerator. The utility model is characterized in that the input shaft of the ringlike decelerator is fixed with a circular ring body cam with a helical tooth groove, the inner side of a housing is fixed with a stator with an inner spherical helical tooth groove, and an output shaft is fixedly connected with a star wheel carrier. The star wheel carrier is uniformly distributed and assembled with a plurality of star wheels. The gear teeth of the star wheel are assembled with rollers. The star wheels are assembled between the stator and the circular ring body cam. The rollers on the gear teeth of the star wheel are respectively engaged with the helical tooth groove of the cam and the helical tooth groove of the stator. The utility model has the advantages of reaching the multiple-point engagement, decreasing the load of stressed components, and enhancing the mechanical efficiency, and the single-stage drive ratio can reach 50. The efficiency is high, the service life is long, the volume is small, and the weight is light.
Description
The utility model belongs to a kind of retarder.
In the last hundred years, transmission component in the retarder is gear and worm screw substantially, a tooth is only arranged or be no more than of the transmission of three teeth at the most during their engagements as power, thereby the stressed load of element (tooth) of the unit's of making transmission power is very big, must cause physical dimension to increase, there is certain relative sliding velocity in weight increase during simultaneously owing to engagement, thereby the portion of energy that consumes become heat-energy losses, so overall efficiency is lower.
The purpose of this utility model provides a kind of loop type speed reducer, can realize the multiple spot engagement, adopts rolling friction to replace sliding friction, improves mechanical efficiency, and volume is little, and is in light weight.
The purpose of this utility model is achieved in that housing, input shaft, the output shaft of retarder, its technological scheme main points are: the cirque body cam of an affixed band spiral alveolar on input shaft of speed reducer, the stator of spherical spiral alveolar in the inboard affixed band of housing, the affixed star wheel frame of output shaft, several star-wheels of uniform assembling on the star wheel frame, assemble roller on the star-wheel gear teeth, star-wheel is assembled between stator and the cirque body cam, and the roller on the star-wheel gear teeth meshes with the spiral alveolar of cam and the spiral alveolar of stator respectively.
The utility model has the advantages that: can realize the multiple spot engagement, reduce the load of forced element, adopt rolling friction to replace sliding friction, thereby improved mechanical efficiency, it has absorbed planetary pinion and worm geared advantage, the system that establishes one's own system is realized the coaxial-type transmission, and single staged transmission ratio can reach 50, the efficient height, life-span is long, and volume is little, and is in light weight.
The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 8 is stator half a slit bamboo or chopped wood schematic representation.
Fig. 9 is embodiment's 2 structural representations.
See Fig. 1-6, the utility model embodiment 1 structure is as follows: the input shaft 5 cirque body cam 6 that is fixedly connected, and cam face has spiral alveolar 11, and its sectional shape is the opening rectangle shown in Fig. 6 a, also can be the semicircle shown in Fig. 6 b, spiral alveolar 11 can be single line, two-wire and multi-thread helix.The housing internal fixation connects stator 1, and stator 1 is combined into one by 2 half slit bamboo or chopped woods, and there is spiral chute 12 stator 1 inboard, and its sectional shape is the opening rectangle, or is semicircle.Output shaft 9 star wheel frame 10 that is fixedly connected uniformly on the star wheel frame 10 is opened 3-6 notch, and each notch connects star-wheel 7 by little axle, and star-wheel 7 a uniform 6-12 gear teeth are assembled roller 2(roller bearing on each gear teeth), promptly on each star-wheel 7 6-12 roller 2 arranged.The roller 2 of star-wheel 7 respectively with stator 1 and cirque body cam 6 on spiral chute engagement.
Working principle: when input shaft 5 drives 6 rotations of cirque body cam, power passed to be distributed on cam 6 circumference and the roller 2 on 3-6 the star-wheel that is engaged with, roller 2 can revolve round the sun again in rotation, roller 2 can mesh with the inner spiral groove tooth of stator 1 again, because stator 1 admittedly easily, give 2 one reaction forces of roller, each roller 2 on the star-wheel assembly 7 alternately advances along inner spiral groove, star-wheel 7 is turned round, thereby driving star wheel frame 10 also rotates, with joining output shaft 5 rotations of star wheel frame, thereby reach output torque and speed change purpose.
See Fig. 7, the utility model embodiment 2 structures: the structure of seeing embodiment 1, output shaft 9 is fixing, be that star wheel frame 10 is fixing with frame 15, housing 8 cancellations of stator 1 outside, stator changes rotor 13 into, and rotor 13 structures are with aforementioned stator structure, outer surface is installed rotating belt 14, and other structure is with embodiment 1.Working principle: because output shaft fixes, star-wheel can't be realized revolution, thereby produces reaction force rotor 13 is rotated, by drivign belt 14 outputs.
