Description
technical field:
The utility model relates to a kind of compact type harmonic speed reducer, is mainly used in mechanical transmissioning technology field.
background technique:
Harmonic gear and traditional involute gear are essentially different, and the latter, when transferring power, is completed by single tooth, the former is completed jointly by a plurality of teeth, therefore, transmit same moment of torsion, the boundary dimension of harmonic gear reducer is little more a lot of than the retarder of involute.
Therefore, harmonic gear, particularly high-precision harmonic gear is the series products that China endeavours exploitation always, its maximum purposes is all kinds of robots, wind-driven generator and all kinds of gearing, for existing speed reducer, it is a revolutionary product, and it has, and transmitting torque is large, size is little, precision is high, the low feature of when work noise.
summary of the invention:
The utility model, for current technology status, provides a kind of compact type harmonic speed reducer, and this harmonic speed reducer is simple and compact for structure, and coaxality is good.
Concrete technological scheme of the present utility model is as follows:
A kind of compact type harmonic speed reducer, comprise generator, flexbile gear, just take turns and left and right housing, right shell body peace end is on the right side of generator axle and be provided with right bearing in both cooperation places, firm wheel with internal tooth is arranged on left shell, flexbile gear front portion is sleeved on generator, and flexbile gear anterior band external tooth is also coupled with firm wheel internal tooth, the inside and outside bearing that is all equipped with in described flexbile gear rear end, flexbile gear rear end inner hole sleeve is contained on generator axle, and at both fitting surfaces, left bearing is housed; Flexbile gear rear portion outer ring sleeve is loaded in left shell, and at both fitting surfaces, flexible support bearing is housed.
Between described flexbile gear front portion and generator, by flexible bearing, coordinate.
Described flexible bearing right side is located by right shell body, and the left side of flexible bearing is provided with spacing back-up ring.
the utility model compared to existing technology, has following features:
(1) compact type harmonic speed reducer of the present utility model, flexbile gear is arranged on generator axle, thereby makes structure compacter.
(2) this harmonic speed reducer coaxality is high;
(3) high conformity between each part;
(4) transmission accuracy is high;
(5) flexible bearing adopts spacing back-up ring to limit the axial displacement of bearing, makes the performance of retarder more stable.

Fig. 1 is outline drawing of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to schematic diagram.
In figure: 1-just takes turns; 2-flexible bearing; 3-right bearing; 4-generator; 5-right bearing lid; 6-right shell body; 7-left shell; 8-flexbile gear; 9-left bearing; 10-left bearing lid; 11-flexbile gear spring bearing; The spacing back-up ring of 12-.
embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, compact type harmonic speed reducer of the present utility model, comprises generator 4, flexbile gear 8, just takes turns 1 and right shell body 6, left shell 7, and right shell body 6 peace ends are at the left end of generator axle 4, and being provided with right bearing 3 in both cooperation places, right bearing 3 outer ends are provided with right bearing lid 5.Just wheel 1 is arranged on right shell body 6 and is provided with internal tooth, and flexbile gear front portion is sleeved on generator 4, and flexbile gear 8 front portions are provided with external tooth and are coupled with firm wheel 1 external tooth.Flexbile gear 8 rear portion inner hole sleeves are contained on generator axle 4 and in both cooperation places and are provided with left bearing 9.Right shell body 6 is sleeved on outer ring, flexbile gear rear end, and is provided with flexbile gear spring bearing 11 at the two fitting surface, and outer end is provided with left bearing lid 10.Flexbile gear 8 rear ends are output terminal.Generator 4 left ends are sleeved in the endoporus of flexbile gear 8; The output terminal of flexbile gear 8 stretches out left shell 7, for power output, is connected with load.
Flexbile gear 8 is anterior to be coordinated by flexible bearing 2 with 4, generator.Flexible bearing 2 is arranged on generator 4.Flexible bearing 2 right sides are located by the positioning step of generator axle, and the left side of flexible bearing 2 is provided with spacing back-up ring 12, and this spacing back-up ring 12, by being connected with generator 4, has guaranteed the axial position of flexible bearing in this way.
Compact type harmonic speed reducer of the present utility model, whole device is placed in left and right housing, between these two housings, with finger setting, and with bolt tightening, is fixed with firm wheel in left shell, and the two to be just to take turns external cylindrical surface location, and with bolt tightening; Just wheel is coupled with flexbile gear, and generator is housed in flexbile gear, between flexbile gear and generator, flexible bearing is housed.
working principle of the present utility model:
During the utility model work, power, by the input of generator right bearing lid end, utilizes harmonic wave principle to reduce the input speed of motor, improves output torque simultaneously, and output torque is from the output shaft end output of flexbile gear.
During power input, generator axle right-hand member is connected with input motor in the mode of key, and power output is exported in the mode of annular keyway, and the large I of output torque is recently adjusted according to the deceleration of retarder.
