Abstract
A kind of flexbile gear for having arc tube structure, including connecting portion and the cylinder that is connected with connecting portion, it is characterised in that：The cylinder includes the external tooth section of front end and the cambered surface cylinder section of rear end, and the outer wall of the cambered surface cylinder section is with raised cambered surface.The connecting portion can be flange.The beneficial effects of the utility model are：After the raised cambered surface of increase, equivalent to the thickness for adding thin-walled, when wave producer acts on flexbile gear inner wall, the flexbile gear amount of being deformed passes through raised cambered surface and can weaken, so that the deformation of flexbile gear bottom linker reduces, the distortional stress of flexbile gear bottom can be reduced, improve flexbile gear service life.
Description
Technical field
The element with teeth for the band of translatory movement is the utility model is related to, is related to harmonic speed reducer, espespecially one kind has arc
The flexbile gear of shape tube structure.
Background technology
Flexbile gear is a core part in harmonic speed reducer, and the flexbile gear tube structure of harmonic speed reducer is straight wall at present
Shape, there is the external tooth of varying number on its thin-wall barrel front end is cylindrical, and stage casing is thin-wall construction, when wave producer loads flexbile gear endoporus
Afterwards, flexbile gear thin-wall barrel can produce certain radial deformation, and when wave producer rotates, flexbile gear is deformed, by external tooth and
Firm gear internal tooth engages, and the thin-wall barrel of flexbile gear transmits torque to correlation reducing gear, and the cylinder stage casing of flexbile gear is just in the course of work
It is related to the Multiple factors such as torsional rigid, the staring torque of harmonic drive, the size and service life of bearing capacity；Harmonic wave at present
The flexbile gear tube structure of retarder is straight wall shape, has the external tooth of varying number on its thin-wall barrel front end is cylindrical, stage casing is thin-walled
Straight barrel structure, as shown in Figure 1：Flexbile gear stage casing thin-wall barrel acts the work for transmitting torque to related reducing gear during the work time
With torsional rigid, the staring torque, the size and flexbile gear service life of bearing capacity etc. for being related to harmonic speed reducer transmission are multiple
Factor.Straight wall cylinder shortcoming：1. the torsion stiffness of flexbile gear cylinder carrying is limited.2. wave producer rotates in flexbile gear,
The stress that deformation of flexible wheel produces directly is delivered to flexbile gear flange base by straight barrel, and such flexbile gear bottom stress is concentrated, flexbile gear
Service life shortens.This is its shortcoming.
The 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 flexbile gear for having arc tube structure.
Be intended to reduce the distortional stress of flexbile gear bottom again, improve flexbile gear service life.
Technical solution is used by the utility model solves its technical problem：There is provided a kind of has the soft of arc tube structure
Wheel, including connecting portion and the cylinder that is connected with connecting portion, it is characterised in that：External tooth section and rear end of the cylinder including front end
Cambered surface cylinder section, the outer wall of the cambered surface cylinder section is with raised cambered surface.
The connecting portion can be flange.
The beneficial effects of the utility model are：After the raised cambered surface of increase, equivalent to the thickness for adding thin-walled, when ripple occurs
When device acts on flexbile gear inner wall, the flexbile gear amount of being deformed passes through raised cambered surface and can weaken, so that flexbile gear bottom connects
The deformation of fitting reduces, and can reduce the distortional stress of flexbile gear bottom, improve flexbile gear service life.
Brief description of the drawings
The utility model will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the flexbile gear structure diagram of the prior art.
Fig. 2 is the structure diagram of the utility model flexbile gear.
In figure：1 be connecting portion, 2 be cylinder, wherein 21 be external tooth section, 2a is straight wall cylinder section, 2b is cambered surface cylinder section.
Embodiment
Referring to attached drawing, a kind of flexbile gear for having arc tube structure of the utility model, including connecting portion 1, be connected with connecting portion 1
Cylinder 2, it is characterised in that：The cylinder 2 includes the external tooth section 21 of front end and the cambered surface cylinder section 2b of rear end, the cambered surface cylinder
The outer wall of body section 2b is with raised cambered surface.
In the embodiment of the utility model, the connecting portion 1 is flange.
Claims (2)
