Description
Technical field
The utility model is related to harmonic speed reducer technical field, and in particular to it is a kind of apply in harmonic speed reducer it is soft
Wheel.
Background technology
Harmonic drive（Harmonic Drive）It is the fifties in last century by American inventor C.Walt Musser Ma Se
Mid-term innovation and creation by the original creation operating principle for applying metallic elastic mechanics and only 3 basic elements of character（Ripple occurs
Device, flexbile gear, firm wheel）The accurate control reductor of composition, harmonic drive has the advantages that other transmissions are not available.At present
Through being widely used in the industries such as electronics, space flight and aviation, robot.
When wave producer loads bowlder in flexbile gear, force flexbile gear to produce elastic deformation and be in ellipticity, make soft at its major axis
Take turns in the teeth groove of the engaging-in firm wheel of the gear teeth, as fully engaged state, and the two-wheeled gear teeth are not contacted completely at its short axle, in disengagement
State, nibbles out or engaging-in state from being engaged to then to be between the process of disengagement.When wave producer is continuously rotated, force soft
Wheel constantly deform, make the two-wheeled gear teeth entrance it is engaging-in, engage, nibble out, disengage during constantly change respective work
State, generates so-called side set motion, it is achieved thereby that the transmission that active wave producer is moved with flexbile gear.In this engagement process
In, to make tooth it is engaging-in, nibble out and smoothly realize, it is necessary to the shape to gear is modified.For this reason, it may be necessary to research and develop a kind of structure
Flexbile gear reasonable in design.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, there is provided a kind of smart structural design, rational harmonic wave flexbile gear
Tooth-shape structure.
To achieve the above object, technical scheme provided by the utility model is：
A kind of harmonic wave flexbile gear tooth-shape structure, it includes a circular disk body, and the home position of the circular disk body is provided with ellipse
Through hole, to the axially extending formation socket part in one side direction, the outer peripheral face of the socket part is provided with for the inner edge of the ellipse hole
Teeth, the teeth groove of the teeth is a width of≤1.31 times of transverse tooth thickness, addendum coefficient is 0.5~0.8.
Used as a kind of improvement of the present utility model, the tooth top of the teeth is provided with the rounding that radius is 0.08mm.
Used as a kind of improvement of the present utility model, the tooth root of the teeth is provided with the rounding that radius is 0.3mm.
The beneficial effects of the utility model are：The utility model smart structural design, rationally, using involute double circular arc tooth
Shape as harmonic wave special tooth form, one is easy for cutter manufacture, and two are easy for detection；And addendum coefficient is small, tooth is high relatively low,
Do not need larger engagement distance to be obtained with big mesh volume, larger moment of torsion can be born；And the facewidth increases, tooth root
Circular arc increases, and reduces the risk that tooth root fracture failure occurs, while engaging logarithm is up to 35~45%, the flank of tooth is smaller than pressing, so that
Deflection is smaller, the service life of flexbile gear can be greatly improved, beneficial to wide popularization and application.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is the teeth positive structure diagram of socket part in Fig. 1.
Specific embodiment
Referring to a kind of harmonic wave flexbile gear tooth-shape structure that Fig. 1 and Fig. 2, the present embodiment are provided, it includes a circular disk body 1, should
The home position of circular disk body 1 is provided with ellipse hole 2, and the inner edge of the ellipse hole 2 is to the axially extending shape in one side direction
Into socket part 3, the outer peripheral face of the socket part 3 is provided with teeth, and the space width e of the teeth is≤1.31 times of transverse tooth thickness, height of teeth top system
Number is 0.5~0.8.For convenience of installing, multiple flange mounting holes are provided with the peripheral position of circular disk body 1.
In the present embodiment, the long axis length d1 of the socket part 3 is that 83.15mm, AL d2 are 82mm, minor axis length
D3 is 81.42mm.The space width e of the teeth is 0.7298 mm, and transverse tooth thickness s is 0.5582 mm, and tooth top is provided with radius R1 and is
The rounding of 0.08mm, tooth root is provided with the rounding that radius R2 is 0.3mm.Mutually fitted with the utility model harmonic wave flexbile gear tooth-shape structure
The long axis length of the steel wheel matched somebody with somebody is 83.966mm, AL is 82.449mm, minor axis length is 82.82mm.Tooth on steel wheel
Thickness is 0.7293 mm.
The utility model smart structural design, rationally, using involute bicircular arcs tooth form as harmonic wave special tooth form, one
Cutter manufacture is easy for, two are easy for detection；Had the advantage that with like product tooth comparision：
1）Addendum coefficient is small, and tooth is high relatively low, it is not necessary to which larger engagement distance is obtained with big mesh volume, can be with
Bear larger moment of torsion；
2）The facewidth increases, the increase of tooth root circular arc, reduces the risk that tooth root fracture failure occurs；
3）The deflection that harmonic wave flexbile gear is used is smaller, can greatly improve the service life of flexbile gear；
4）The engagement logarithm of tooth is up to 35 ~ 45%, and the flank of tooth is smaller than pressing.
The announcement and teaching of book according to the above description, the utility model those skilled in the art can also be to above-mentioned reality
The mode of applying is changed and changed.Therefore, the utility model is not limited to specific embodiment disclosed and described above, right
Some modifications and changes of the present utility model should also be as falling into scope of the claims of the present utility model.Additionally, to the greatest extent
Some specific terms have been used in pipe this specification, but these terms are merely for convenience of description, not to the utility model
Any limitation is constituted, using the tooth-shape structure of same or similar other structures, in the utility model protection domain.
