Description
Technical field
The utility model is related to harmonic speed reducer fields, refer in particular to a kind of right-angled intersection needle bearing with internal tooth.
Background technology
Harmonic speed reducer is a kind of new, high-precision transmission decelerating device, mainly by wave producer, flexbile gear and firm gear
Three basic building blocks composition, it makes flexbile gear generate controlled elasticity to deform by wave producer, and is meshed with firm gear to transfer movement
And power.Harmonic speed reducer must assemble right-angled intersection needle bearing again, can be just that it has outstanding bending resistance.Generation at present
The running part for the state-of-the-art emulated robot developed in boundary, using humorous at leg, arm, finger, trunk
Ripple retarder.And the limitation of the contour structures of robot finger joint, inside the space installed and used for retarder and again
Amount is all greatly limited.Therefore, the present inventor makes further research this, develops a kind of right-angled intersection with internal tooth
Thus needle bearing, this case generate.
Utility model content
The purpose of this utility model is to provide a kind of right-angled intersection needle bearings with internal tooth, greatly have compressed machine
The axial dimension of people's harmonic speed reducer.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of right-angled intersection needle bearing with internal tooth, including inner ring, outer ring, the inner ring, the equivalent width of outer ring, and
Inner ring and outer ring offer opposite 90 ° of V-groove, and the V-groove is provided with needle roller, and the inner ring offers valve, institute
It states needle roller and V-groove is packed by valve, the valve is fixed by screw；The contact surface of inner ring and flexbile gear is provided with internal tooth,
Outer ring is equipped with the screw via being connected with Rigid Gear of Harmonic Reducer.
Further, the inner ring, outer ring V-groove by be provided with oil sealing.
Further, slim steel ring is provided between the oil sealing and inner ring, the slim steel ring agrees with oil sealing.
After using the above program, the utility model compared with prior art, has the following advantages：
With very good bending resistance square ability and robust motion, this product is made to possess excellent sealing effect, internal tooth
It can greatly reduce axial dimension with the flexbile gear perfect cooperation of harmonic speed reducer, disclosure satisfy that robot harmonic reduction
Device is that solid basis has been established in the research and development of ultrathin harmonic speed reducer to the requirements of bearing.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model；
Label declaration
Inner ring 1, internal tooth 11, outer ring 2, needle roller 3, valve 4, screw 5, oil sealing 6,
Slim steel ring 7.
Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments.
As shown in the figure, a kind of 3 bearing of right-angled intersection needle roller with internal tooth 11, including inner ring 1, outer ring 2, inner ring 1, outer ring 2
Opposite 90 ° of V-groove is offered, needle roller 3 is provided in V-groove, due to the presence of needle roller 3, there is very prominent resist
Moment of flexure ability.
Inner ring 1 offers valve 4, and needle roller 3 intersects loading by valve 4, is connected again with trip bolt 5 after installing, and is formed
3 track of complete needle roller, will not have any impact to the operation of needle roller 3.
For inner ring 1 through Overheating Treatment, hardness is high, not easy to wear, the contact surface of flexbile gear is provided with internal tooth 11, internal tooth 11 can
With the flexbile gear perfect cooperation of harmonic speed reducer, axial dimension is greatly reduced, disclosure satisfy that robot harmonic speed reducer pair
Solid basis has been established in the requirements of bearing, the research and development for ultrathin harmonic speed reducer.
The slim steel ring 7 of hot insert one again in inner ring 1, has a good surface smoothness, and 6 perfect cooperation of oil sealing, very well
Solve Leakage.
Above are only specific embodiment of the utility model, at the same in all the utility model it is involved as " it is upper and lower, left,
The words such as right, centre " are only used as to refer to, not absolute limit, and all changes that unsubstantiality is carried out using the utility model should all
It falls into the category of infringing the protection scope of the present invention.
