Description
Technical field
The present invention relates to a kind of mixing planetary type gear transmission unit.
Background technique
Existing RV transmission device sees Patent Office of the People's Republic of China with CN1366590A invention disclosed patent: " transmission device of internal-meshing planetary gear construction " and be published in paper on the 2nd phase of " Dalian Railway University's journal " June in 1999 " robot with the research of highi degree of accuracy RV transmission ".The deficiency of existing RV transmission device is that eccentric shaft places within the internal gear, makes the size of the rotary arm bearing on the eccentric shaft be subjected to the restriction of internal gear diameter.Simultaneously, because the operating conditions of rotary arm bearing is more abominable, the operating life of rotary arm bearing is shorter, often directly influences the life-span of whole transmission device.
In addition, the external tooth wheel plate of existing RV transmission device has only two, but the inertial force balance that eccentric shaft produced in the RV transmission of two external gear plate structures, but the moment of inertia that inertial force produced can not balance, the dynamic performance of transmission device be certainly will influence like this, vibration and noise particularly under the high-speed motion situation, easily produced.
Summary of the invention
The objective of the invention is above-mentioned deficiency, design a kind of new structure RV transmission device, change position of eccentric, thereby the restrictive condition of rotary arm bearing size is improved and the mechanical property of transmission device is improved at disclosed RV transmission device.
Technological scheme of the present invention is: novel ring-plate structure RV transmission device, comprise body, be installed in sun gear on the input shaft, be installed on the eccentric shaft with the sun gear planet gear meshed, be installed in internal gear ring plate on the eccentric shaft, pass equal support plate that internal gear ring plate connects and output axillare, bearing with joining shaft.Its structure is: also comprise an external gear that is fixedly mounted on the body front end-plate, describedly be installed in internal gear ring plate on the eccentric shaft 5 and be meshed with external gear on being installed in the body front end-plate.
New type annular plate type RV actuator of the present invention, its structure is: a plurality of planetary pinions and sun gear engagement; Multiple-eccentric shaft mechanically is connected to corresponding planetary pinion; Many joining shafts pass the gear ring flat-plate and mechanically connect output axillare and equal support plate.
New type annular plate type RV actuator of the present invention, its structure is: described internal gear ring plate adopts three gear ring plate structures, the quality of middle internal gear ring plate is the twice of the quality of both sides internal gear ring plate, and eccentric shaft is spent with the eccentric phase difference mutually 180 on the internal gear ring plate of both sides in the eccentric phase place on the middle internal gear ring plate; Middle internal gear ring plate and both sides internal gear ring plate respectively be installed in the body front end-plate on external gear be meshed.
New type annular plate type RV actuator of the present invention is characterized in that: described internal gear ring plate adopts cycloid pin tooth profile of tooth or involute tooth profile of tooth to be meshed with the engagement of external gear on being installed in the body front end-plate.
New type annular plate type RV actuator of the present invention, its structure is: described input shaft and output shaft are the hollow shafts of solid shaft or band inner spline groove.
Major advantage of the present invention is:
Because the structure that the external gear on the present invention adopts internal gear ring plate and is installed in the body front end-plate is meshed, make the internal gear that is arranged on the body change the external gear that is installed on the body front end-plate into, eccentric shaft and rotary arm bearing are placed outside the gear engagement, thereby the size that makes rotary arm bearing is not subjected to the restriction of gear diameter, the selection of bearing has had bigger space, and the life-span of rotary arm bearing can be improved.
Owing to adopt three gear ring plank frames, if the quality of internal tooth wheel plate is the twice of the quality of both sides internal tooth wheel plate wherein, eccentric shaft is spent with the eccentric phase difference mutually 180 on the internal tooth wheel plate of both sides in the eccentric phase place on the middle internal tooth wheel plate.Just can guarantee balance of shaking force that eccentric shaft produced and moment of inertia balance all the time, make transmission device remain dynamic balancing, improve the dynamic performance of transmission device.
Input shaft of the present invention and output shaft respectively have two kinds, and a kind of is solid shaft, and the 2nd, hollow shaft; The solid shaft structure is suitable for and the connecting of the axle of coupling or hollow, and hollow shaft structure is suitable for directly and spool connects.
Bearing on the support of the present invention can adopt no preload or preload hollow roller bearing, no preload or the dark cave of preload hollow roller bearing according to the needs of using operating mode, can also adopt the roller bearing of dark cave roller bearing and surperficial correction of the flank shape; The fatigue life of adopting the roller bearing of dark cave roller bearing and surperficial correction of the flank shape can improve bearing; The fatigue life of adopting no preload hollow roller bearing, the dark cave of no preload hollow roller bearing can improve bearing, improve the tolerance ability and the running accuracy of axle system, can also improve stability of vibration; Adopt the preload hollow roller bearing, bear the fatigue life that dark cave hollow roller bearing can improve bearing in advance, improve the tolerance ability and the running accuracy of axle system, can also improve stability of vibration, particularly increased the rigidity that axle is.
Working principle of the present invention is: according to the theory of engagement, when input shaft rotated, the sun gear that is installed on the input shaft drove three planet wheels rotations, and planet wheel is done rotation around the axis of self on the one hand, does revolution around the axis of sun gear on the other hand.Simultaneously, planet wheel drives the rotation that eccentric shaft is being done identical not only rotation but also revolved round the sun, eccentric shaft just drives middle internal gear ring plate and the motion of both sides internal gear ring plate with corresponding eccentric phase difference, and middle internal gear ring plate and both sides internal gear ring plate are done cycloid motion under the constraint of body external gear; Meanwhile, output axillare and output shaft are with the revolution motion output of eccentric shaft.
Lower in speed, under the less operating conditions of inertial force, the present invention also can adopt two ring-plane structures, two gear ring flat-plates identical in quality, and it is poor that the eccentric phase place of eccentric shaft on two internal gear ring plate has respective phase.Two ring-plane structures are axially having less size than three ring-plane structures.Also can adopt three three ring-plane structures that the gear ring flat-plate is identical in quality, it is poor that the eccentric phase place of eccentric shaft on three internal gear ring plate has respective phase.
