Description
Technical field
What the present invention relates to is a kind of orthogonal formula steering wheel planetary reducer transmission device.
Background technique
Orthogonal formula harmonic wave drive speed reducer due to its reduction speed ratio large, volume is little, lightweight, output torque is large, transmission accuracy high, be widely used in all trades and professions multiple fields, but, its orthogonal formula harmonic wave drive speed reducer is subject to the impact of two-stage transmission and harmonic wave deformation wave, the transmission efficiency of its product does not increase all the time, the harmonic speed reducer efficiency of single-stage only has about 75%, add the bevel gear drive of one-level, total transmission efficiency just only has about 50%, for the user of ask for something transmission efficiency height use occasion, must be subject to certain restrictions, there is certain defect.
The design of orthogonal formula planetary reducer is also realized by double reduction mechanism, one-level is bevel gear transmission equally, one-level is single ripple planet eccentric speed reduction structure in addition, its volume is equal to the volume with orthogonal formula harmonic driving, mounting interface is also consistent with it, possesses that reduction speed ratio is large, volume is little too, lightweight, output torque large, transmission accuracy high.The transmission efficiency of its product can realize about 90%.Its working life same also improves relatively.
Summary of the invention
The object of this invention is to provide a kind of orthogonal formula planetary reducer transmission device, fill up orthogonal formula harmonic wave drive speed reducer transmission efficiency and life-span deficiency, realize the features such as reducer reduction speed ratio is large, volume is little, lightweight, output torque is large, transmission accuracy is high, transmission efficiency is high, the life-span is long.
Orthogonal formula planetary reducer, it is characterized in that comprising motor high speed input part, one-level bevel gear gearing down pair, secondary planet gear reduction driving mechanism, and described one-level bevel gear drive comprises bevel pinion, bevel gear wheel, bevel pinion is by the motor shaft of straight pin tight joint in motor high speed input part, bevel gear wheel structure, with eccentric structure, is connected with planetary pinion in secondary planet gear reduction driving mechanism by bearing; Described secondary planet gear reduction comprises: compound planet gear, the housing of band ring gear; Planetary rotation by housing internal gear restriction and planetary pinion does plane motion; Planetary pinion and internal gear are the meshed transmission gear of a pair few teeth difference, and planetary pinion is a duplicate gear, and output shaft joins gears meshing with planetary another simultaneously, are a pair few teeth difference engagement output form equally; Resetting shaft is connected firmly mutually by screw and setting circle pin and output shaft, and resetting shaft passes through again and is with the bevel gear wheel endoporus of eccentric structure and potentiometer to be connected simultaneously.
Motor of the present invention realizes orthogonal transmission by the bevel gear that pair of orthogonal engages, double-planetary gear is driven to rotate by being with the bevel gear wheel of eccentric structure, planetary rotation is by the restriction of internal gear, planet crop rotation plane motion, namely planet wheel both circled around fixed axis, also do rotation motion around own axes, planetary pinion and internal gear are the meshed transmission gear of a pair few teeth difference, sun gear joins gears meshing with planetary another as output mechanism simultaneously, be a pair few teeth difference engagement output form equally, thus achieve the object of deceleration.
The present invention has the features such as compact structure, volume is little, velocity ratio is large, transmission accuracy is high, transmission efficiency is high, the life-span is long.
Accompanying drawing explanation
Figure is orthogonal formula planetary reducer structural representation.
Figure number illustrates: 1 motor, 2 housings (band ring gear), 3 bevel pinions, 4 potentiometers, 5 bevel gear wheels (band eccentric structure), 6 planetary pinions (double structure), 7 output shafts (band ring gear), 8 end caps, 9 resetting shafts.
Concrete enforcement
As shown in the figure, this orthogonal formula planetary reducer, comprises motor input at a high speed, one-level bevel gear gearing down pair, the transmission of secondary planet gear reduction.Described one-level bevel gear drive comprises: bevel pinion 3, bevel gear wheel 5, bevel pinion 3 passes through straight pin tight joint on motor shaft, motor 1 drives bevel pinion 3 to rotate, bevel pinion 3 drives bevel gear wheel 5 by orthogonal manner, thus achieve primary speed-down, bevel gear wheel structure, with eccentric structure, is connected with planetary pinion (duplicate gear) 6 by bearing; Secondary planet gear reduction comprises: drive double-planetary gear 6 to rotate by being with the bevel gear wheel 5 of eccentric structure, the rotation of planetary pinion 6 is subject to the restriction of housing internal gear 2, planet crop rotation plane motion, namely planet wheel both circled around fixed axis, also do rotation motion around own axes, planetary pinion and internal gear are the meshed transmission gear of a pair few teeth difference, planetary pinion is a duplicate gear, output mechanism joins gears meshing with planetary another simultaneously, be a pair few teeth difference engagement output form equally, thus achieve the object of deceleration.The information feed back of potentiometer 4: resetting shaft 9 is connected firmly mutually by screw and setting circle pin and output shaft 7, resetting shaft 7 passes through again bevel gear wheel 5 endoporus of band eccentric structure simultaneously, and be connected with potentiometer 4, potential monitoring is to the powertrain information of retarder.Thus receive information respective handling.
