Abstract
A kind of harmonic speed reducer, including wave producer, flexbile gear, firm gear and intersection bearing, it is characterised in that：The flexbile gear is cup configuration, is flexbile gear tooth in the front end of flexible cylinder；The firm gear is hollow carnival hat type firm gear structure, has internal tooth to be adapted to flexbile gear tooth in firm gear endoporus, and outside is made of the cylindrical surface of two various outer diameters, and there are several holes in the end face of big cylinder；There is a fixed block, flexbile gear is fixed in the middle part of the fixed block, and both ends of the surface there are several threaded holes on fixed block, and described threaded hole one end, which is fixed, intersects bearing outer ring, and the other end is used to connect external component.It is more that its advantage is that of avoiding existing retarder flexbile gear, firm gear materials, and processing technology is complicated, shortcoming of high cost, save the materials of harmonic speed reducer, processing technology is simplified, is ensureing harmonic speed reducer service precision and in the case of the service life, is reducing processing cost.
Description
[technical field]
The element with teeth for the band of translatory movement is the utility model is related to, is related to a kind of harmonic speed reducer.
[background technology]
The deceleration transmission component of intelligent industrial robot uses harmonic speed reducer mostly, and harmonic reduction transmission is a kind of dependence
Controlled elasticity deformation is driven to transmit the novel mechanical of movement and power caused by flexible gear, its basic building block includes ellipse
Wave producer, thin-wall barrel shape flexbile gear and have fine rigid firm gear.When wave producer rotates, flexbile gear is forced to produce bullet
Property deformation, its tooth and firm gear tooth is interacted, so as to fulfill the purpose of transmission.The deceleration of existing intelligent industrial robot
Device is divided into cup type and hollow two major class of carnival hat type according to the difference of flexbile gear structure, and cup type harmonic reduction uses dedicated intersection
Bearing, flexbile gear is a cup-shape, therefore referred to as cup type, its structure is few relative to hollow carnival hat type flexbile gear materials, but phase therewith
The firm gear materials matched somebody with somebody are more, and processing is also more complicated.Hollow carnival hat type harmonic speed reducer because of flexbile gear structure as carnival hat so gain the name,
And dedicated intersection bearing is used, what its structure and cup type used intersect, and bearing is different, hollow carnival hat type harmonic reduction flexbile gear
The material used compares for cup type, more using material, and flexbile gear processing technology is complicated, but it is firm to match with carnival hat flexbile gear
It is then less to take turns dosage.That is：Existing cup type harmonic speed reducer is its advantage less using flexbile gear material, but matched firm
It is more to take turns materials, processing is also more complicated, this is its shortcoming；And hollow carnival hat type harmonic speed reducer then subtracts with cup type harmonic wave
Fast device is on the contrary, hollow carnival hat type harmonic reduction flexbile gear is more using material, and flexbile gear processing technology is complicated, this is its deficiency
Place, but it is then less with firm gear dosage that carnival hat flexbile gear matches, and this is then its advantage.
[content of the invention]
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of new harmonic speed reducer.It is intended to
Two kinds of harmonic speed reducers of the cup type of the prior art and hollow carnival hat type are maximized favourable factors and minimized unfavourable ones, overcome its shortcoming, it is humorous to reach saving
The materials of ripple retarder, simplify processing technology, and in guarantee harmonic speed reducer service precision and in the case of the service life, reduction is processed into
This purpose.
Technical solution is used by the utility model solves its technical problem：A kind of harmonic speed reducer, including ripple are provided
Generator, flexbile gear, firm gear and intersection bearing, it is characterised in that：The flexbile gear is cup configuration, is soft in the front end of flexible cylinder
The gear teeth；The firm gear is hollow carnival hat type firm gear structure, has internal tooth to be adapted to flexbile gear tooth in firm gear endoporus, and outside is by two differences
The cylindrical surface of outside diameter is formed, and there are several holes in the end face of big cylinder；There is a fixed block, flexbile gear is fixed in the middle part of the fixed block,
Both ends of the surface have several threaded holes on fixed block, and described threaded hole one end, which is fixed, intersects bearing outer ring, and the other end is used to connect outside
Component.
The beneficial effects of the utility model are：It is more to avoid existing retarder flexbile gear, firm gear materials, processing technology is complicated,
Shortcoming of high cost, saves the materials of harmonic speed reducer, simplifies processing technology, is ensureing that it is smart that harmonic speed reducer uses
In the case of degree and service life, processing cost is reduced.

The utility model will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the cup type harmonic speed reducer structure diagram of the prior art.
Fig. 2 is the hollow carnival hat type harmonic speed reducer structure diagram of the prior art.
Fig. 3 is the structure diagram of the utility model.
Fig. 4 is 2 structure diagram of flexbile gear of the utility model.
Fig. 5 is 3 structure diagram of firm gear of the utility model.

In figure：1 be wave producer, 2 be flexbile gear, 22 be flexible cylinder, 23 be flexbile gear tooth, 3 be firm gear, 4 be intersect bearing,
5 it is fixed block, 51 is threaded hole.
[embodiment]
Referring to attached drawing, a kind of harmonic speed reducer of the utility model, including wave producer 1, flexbile gear 2, firm gear 3 and intersection bearing
4, it is characterised in that：The flexbile gear 2 is cup configuration, is flexbile gear tooth 23 in the front end of flexible cylinder 22；The firm gear 3 is hollow
Carnival hat type firm gear structure, has internal tooth 31 to be adapted to flexbile gear tooth 23 in firm gear endoporus, exterior cylindrical surface 32 by two various outer diameters,
33 are formed, and there are several holes 34 in the end face of big cylinder；There is a fixed block 5, flexbile gear 2 is fixed in the middle part of the fixed block, fixed block
Upper both ends of the surface have several threaded holes 51, and described threaded hole one end, which is fixed, intersects 4 outer ring of bearing, and the other end is used to connect exterior portion
Part.
