Description
The present invention relates to the involute gear epicyclic transmission mechanism, relate more particularly to mixed few-differential involute gear epicyclic transmission mechanism and device.
In " the mixed few-differential involute planetary transmission device " of on April 1st, 1985 application (application number: 85100376) and " mixed few-differential involute gear epicyclic transmission mechanism and the device " applied in 1987 (application number: 87102061) set forth in twice patent application document by two pairs of inside engaged gears pay the gearing down formed and more than three pairs or three pairs inside engaged gear pay the speed change of forming transmission, do not pay the gearing down formed and pay the speed change of forming transmission but relate to by two pairs of inside engaged gears by a pair of inside engaged gear.
The purpose of this invention is to provide a kind of its velocity ratio not only by pay by two pairs of inside engaged gears form and also by paying the mixed few-differential spider of forming retarder by a pair of inside engaged gear as special case.
Another free-revving engine of the present invention provides a kind ofly pays the mixed small teeth difference star transmission of forming two velocity ratios by two pairs of inside engaged gears.
Another important purpose of the present invention is to adopt the rolling star-wheel as the rotation transfer mechanism between the planetary pinion.
The object of the present invention is achieved like this: mixed few-differential spider retarder of the present invention has in two pairs meshed gears pay, the planetary pinion of every pair of gear pair is enclosed within on two crankshafts as power input bent axle rotationally, is bound up with the rolling star-wheel again between two planetary pinions; The internal gear that a pair of inside engaged gear is paid is fixed, and another internal gear and pto that inside engaged gear is paid is solidified as a whole.Describedly pay the planetary-gear speed reducer of forming by a pair of inside engaged gear and be meant and keep and internal gear that pto is solidified as a whole and the planetary pinion that is meshed with it, cancelling another pays inside engaged gear and replaces star-wheel seat (being retainer ring), rotation transfer mechanism between star-wheel seat and the planetary pinion adopts the rolling star-wheel, be provided with the consistent and the same number of halving hole of center circle on planetary pinion and star-wheel seat, the rolling bearing on the rolling star-wheel is packed in the halving hole; In like manner, also can keep another inside engaged gear is paid, and cancellation is paid with a pair of inside engaged gear that pto connects, the star-wheel seat then is solidified as a whole with pto, and other is because of the above.Describedly pay the mixed small teeth difference star transmission of forming two velocity ratios by two pairs of inside engaged gears, be on the basis of paying the planetary-gear speed reducer of forming by two pairs of inside engaged gears, to realize, that is: connect by the rolling star-wheel between the planetary pinion, on rolling star-wheel intermediate cylindrical, load onto bearing, as support, star-wheel seat and input end internal gear are all rotatable with a star-wheel seat, when fixing star-wheel seat, the input end internal gear rotates, and is then paid by a pair of inside engaged gear and forms a close steps; When fixing input end internal gear, the rotation of star-wheel seat is then paid by two pairs of inside engaged gears and is formed a big speed ratio.Adopt the rolling star-wheel as rotation transfer mechanism between the described planetary pinion or between planetary pinion and the star-wheel seat, the rolling star-wheel has three sections cylindrical crank throws, middle one section cylindrical body is around the center line rotation of self and around the revolution of retarder center line, so claim that it is a star-wheel, on the cylinder of crank throw two ends rolling bearing is housed all, insert respectively in the planetary pinion halving hole, as be used for speed changer, then in the middle of one section cylinder rolling bearing also is housed and the halving hole of the star-wheel seat of packing in; Because the star-wheel kinematic pair is rolling bearing, so claim that this kind rotation transfer mechanism is the rolling star-wheel, adopt the rotate mixed few-differential involute tooth cam planet driving device of transfer mechanism of rolling star-wheel to abbreviate mixed few-differential spider retarder (can make speed increaser) and speed changer as.
It is that spur wheel is paid that inside engaged gear of the present invention is paid, and its gear is poor, the throw of eccentric of modulus and corresponding crankshaft respectively can be similar and different.
Above-mentioned mixed few-differential involute gear epicyclic transmission mechanism is a basic structure, its power input shaft connection is gone up power input magazine just the mixed few-differential spider retarder and the speed changer series of various needs capable of being combined, it is horizontal, vertical, backstroke, the side formula that its installation form has, and output form has cylinder axis type, end face pawl, inner splined hole, the two keyholes of interior list etc. multiple.
