Abstract
The utility model relates to a well casement harmonic speed reducer ware is refered in particular to in harmonic speed reducer ware field, including body, wave generator, flexbile gear, circular spline, the circular spline is inlayed at this internally, flexbile gear and the meshing of circular spline part, wave generator sets up in the flexbile gear, and wave generator's inside has seted up axial through -hole, and the electric wire is arranged from the inside line of walking of through -hole. After adopting above -mentioned scheme, avoided the cable to expose outside for the cable is not fragile.
Description
Technical field
The utility model relates to harmonic speed reducer field, refers in particular to a kind of hollow type harmonic speed reducer.
Background technique
Speed reducer is a kind of power transmission mechanism, utilizes the velocity transducer of gear, and the winding number of electric motor is decelerated to desired winding number, and obtains the mechanism of larger torque.Speed reducer of a great variety, model is different, variety classes has different purposes, wherein harmonic wave speed reducing machine is a kind of a kind of Novel speed reducer utilizing Planetary Gear Transmission principle to grow up, because its bearing capacity is high, velocity ratio is large, and volume is little, lightweight, stable drive and transmission accuracy these particular advantages high, make harmonic wave speed reducing machine be widely used in the industries such as electronics, space flight and aviation, robot.
The coupling shaft of existing harmonic wave speed reducing machine is generally solid, when harmonic wave speed reducing machine connect two need between the parts of transmission, to need trace arrangements time, electric wire can only carry out arrangement and install in the outside of harmonic wave speed reducing machine, cable etc. is so not only made to be exposed to outside, add installing space, increase installation difficulty, and easily damage, also add the length of cable, cause unnecessary waste.
Therefore, the present inventor makes further research this, and develop a kind of hollow type harmonic speed reducer, this case produces thus.
Model utility content
The purpose of this utility model is to provide a kind of hollow type harmonic speed reducer, avoids cable and is exposed to outside, make cable not fragile.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of hollow type harmonic speed reducer, comprise body, wave-generator, flexbile gear, just take turns, described firm wheel is embedded in body, described flexbile gear engages with firm part of taking turns, described wave-generator is arranged in flexbile gear, and the inside of wave-generator offers axial through hole, and electric wire is from the inner cabling arrangement of through hole.
Further, the one end on described wave-generator offers input screw, and described firm wheel offers output screw.
Further, also comprise and just take turns integrated load, described load correspondence exports screw and offers corresponding screw.
Further, deep groove ball bearing is provided with between described firm wheel and body.
After adopting such scheme, the utility model compared with prior art, has the following advantages:
Save the material of general harmonic speed reducer loading section, reduce manufacture cost; During conducting transmission line arrangement, cable passing in through hole, can avoid cable and being exposed to outside, making cable not fragile, but also decrease the length of cable, avoid unnecessary waste; The integration of firm wheel and load, greatly reduces the axial dimension of harmonic speed reducer entirety.Further improvement of the present invention, just between wheel and body, has been provided with two deep groove ball bearings, has greatly improved stability of rotation and the bending resistance of this kind of hollow type harmonic speed reducer.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Label declaration
Body 1, wave-generator 2, through hole 21, flexbile gear 3, just takes turns 4, upper shell 5,
Input screw 6, exports screw 7.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in the figure, a kind of hollow type harmonic speed reducer that the utility model discloses, comprise body 1, wave-generator 2, flexbile gear 3, just take turns 4, described firm wheel 4 is embedded in body 1, deep groove ball bearing is provided with between firm wheel 4 and body 1, firm wheel 4 is integrated with load, and the output screw 7 just wheel 4 offered is corresponding with the through hole 21 that upper shell 5 is offered; Flexbile gear 3 with just take turns 4 parts and engages, wave-generator 2 is arranged in flexbile gear 3, and the one end on wave-generator 2 offers and inputs screw 6, and power source is by being connected rear input with wave-generator 2.The inside of wave-generator 2 offers axial through hole 21, and electric wire is from the inner cabling arrangement of through hole 21.
Working principle: power inputs, wave-generator 2 is driven to rotate, when wave-generator 2 rotates continuously, the distortion of flexbile gear 3 constantly changes, flexbile gear 3 is also constantly changed with the engagement of just taking turns 4, by engaging-in, engage, nibble out, throw off, engaging-in again, carry out again and again, thus realize flexbile gear 3 and relatively just taken turns 4 along the rightabout slow circumvolve of wave-generator 2.And cable passing in through hole 21, can avoid cable and being exposed to outside, make cable not fragile, but also decrease the length of cable, avoid unnecessary waste; The integration of firm wheel 4 and load, greatly reduces the axial dimension of harmonic speed reducer entirety.
Above are only specific embodiment of the utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
