Description
Technical field
The utility model is related to operated implement fields, more particularly to a kind of card for harmonic wave speed reducing machine firm gear Gear Shaping
Tool and lathe.
Background technology
Harmonic speed reducer is a kind of transmission gear means for realizing movement and power transmission by flexible gear flexible deformation.
In general, harmonic speed reducer is made of basic building blocks such as wave producer, flexbile gear, firm gear and flexible bearings.Wave producer with
In flexbile gear relative rotation, flexbile gear is forced to generate elliptoid radial deformation in its longitudinal end according to certain rules.Flexbile gear at work
The tooth at long axis both ends is engaged with firm gear, and then completely disengaged at short axle.With the continuous relative rotation of wave producer and flexbile gear,
So that deformation of flexible wheel constantly converts, the flexbile gear gear teeth and firm gear cycle carry out side set transmission that is engaging-in, engaging, nibble out, disengaging.Due to
Harmonic drive has the characteristics that precision is high, transmission ratio is big, efficient, small, return difference is small, can transmit movement to confined space,
It is therefore widely used in each field such as robot, space technology, electronic manufacturing technology, there is nearly 90% harmonic gear at present
Device is applied in robot industry and is needed in the industry of progress precision positioning.
About the processing method of Rigid Gear of Harmonic Reducer, have some patents, as Chinese patent CN106141598A is disclosed
A kind of processing method of the high-accuracy Rigid Gear of Harmonic Reducer of robot comprising determine that the facewidth of two toothrows and root circle are straight respectively
Diameter；It is turned into the first cylindrical surface by the root diameter of the first toothrow in firm gear green body inner ring side, is reserved on the cylindrical surface
The axial length of the first toothrow facewidth；In the firm gear green body inner ring other side the second circle is turned by the root diameter of the second toothrow
Cylinder is reserved with the axial length of the second toothrow facewidth on the cylindrical surface；Intersection on the first cylindrical surface and the second cylindrical surface
Process annular groove；Reserved part on the first and second cylindrical surface processes tooth respectively according to determining tooth parameter.The present invention can be
The tooth of the two rows of different numbers of teeth of firm gear inner circumferential machine-shaping, can basis in transmission process with the tooth engagement of corresponding flexbile gear
It needs that any one tooth is selected to be driven, transmits two kinds of transmission ratios to achieve the purpose that realize, meet robot to transmission
The requirement of ratio.
For another example Chinese patent CN102678881A disclose a kind of firm gear for short cylinder flexible gear harmonic reducer and flexbile gear and
Its processing technology, it is related to a kind of firm gear of short cylinder flexible gear harmonic reducer and flexbile gear and its processing technology.The internal tooth of firm gear is
The gear teeth with inclined angle alpha, inclined angle alpha inclined direction is consistent with subtended angle direction θ 2 of the flexbile gear at long axis, and inclined angle alpha is 0.1 °
~2 °.The top of two sections of tooth curve sections of flexbile gear external tooth flank profil is linked together by tooth top straightway, each tooth curve
Section is connected smoothly by upper arc radius and lower arc radius.Harmonic speed reducer includes firm gear, flexbile gear and wave producer；
The ratio between the length of flexbile gear and its internal diameter are less than 1.Flexbile gear in short cylinder flexible gear harmonic reducer is with firm gear by low-speed WEDM
Obtained from machine tooling.The flexbile gear gear teeth in the present invention are engaged with the firm gear gear teeth at certain inclination angle, more without inclination angle
When compare, the total contacts area of all rodent populations improve 15%, to improve the registration of harmonic gear, and then improve humorous
The rigidity of wave transmission.
Above-mentioned each method both for firm gear control process, all not to firm gear in process step up to fill
It sets and is improved, the scheme that especially firm gear stressing conditions are improved.Make firm gear tooth when it would therefore be highly desirable to propose a kind of processing
Base uniform force, will not damage firm gear gear blank machined surface firm gear gear hobbing process fixture.
