The present invention is described more detail below, illustrative examples of the invention and explanation are used for explaining the present invention herein, It is but not as a limitation of the invention.
The method for processing and assembling of public service robot driver, it comprises the following steps:
In interior axle one end and hollow outer shaft one end elastic conjunction stop tab;Interior outer shaft can be driven respectively by two motors, It can be driven respectively by two different transmission mechanisms by a motor;Stop tab can make driving wheel installed in the specific bit of axle Put, avoid driving wheel from moving axially.
Process and assemble hole is distinguished on two elliptical drive for wheel, elliptical drive for wheel can be arranged on by pilot hole corresponding On axle;Two elliptical drive for wheel can drive the gear of the different numbers of teeth, wave producer of the elliptical drive for wheel as harmonic speed reducer.Make For wave producer when, can have axially arranged several rollers in the peripheral distribution of the elliptical drive for wheel, can thus drive two The flexbile gear of the individual different numbers of teeth rotates, so as to export the power of different drive ratios.
One ring spring is set in each pilot hole;In implementation process, radially add along each pilot hole hole wall Work has annular groove, and the ring spring is arranged in corresponding annular groove, and elliptical drive for wheel is fixedly mounted on corresponding by corresponding ring spring On axle;So on the one hand elliptical drive for wheel can be avoided directly to be contacted with corresponding axle and damage elliptical drive for wheel, the opposing party's donut The elastic force of spring can make assembling more convenient;Meanwhile elliptical drive for wheel can even be carried out with respective shaft by the way of gap coordinates Transmission, avoid both from contacting, wear phenomenon occur, and when the effect of attrition of axle and ring spring is driven, only need to change ring spring i.e. Can, save maintenance and maintenance cost.In the present invention, ring spring is the elasticity part for having radical elasticity, in the effect of its elastic force Under, elliptical drive for wheel can be fixed on axle, ensure that axle drives elliptical drive for wheel to rotate.
Two elliptical drive for wheel are separately mounted on the interior outer shaft by pilot hole, and make driving wheel and stop tab phase Connect;Stop tab includes the axial interstage sleeve with respective shaft interference fit, stop tab is rotated with axle, interstage sleeve one end has radially extended gear Piece, the ring spring are fixed and are set on interstage sleeve, can make ring spring is not direct to be contacted with axle, avoid damaging ring spring, described first is oval Driving wheel and the second elliptical drive for wheel axially connect with catch, prevent driving wheel from moving axially;The interstage sleeve perisporium forms Axially arranged several double wedges, each double wedge are radially into the gap of ring spring, so as to block ring spring, so can ensure that ring spring with Axle rotation.
Then interior axle is arranged on hollow outer shaft inner chamber, and the interior axle other end is stretched out the hollow outer shaft other end;As excellent Choosing, the interior axle are arranged on hollow outer shaft inner chamber by bearing;Specifically, the hollow outer shaft both ends are machined with receiving respectively Space, each receiving space is interior to be fixedly mounted a bearing, and the interior axle both ends are arranged on hollow by the two bearings Outer shaft inner chamber;When interior axle is installed, the interior axle other end is first penetrated into inner chamber from the bearing of one end described in hollow outer shaft, then from hollow The bearing of the outer shaft other end passes.Preferably, first placing hollow outer shaft vertically, its described one end is above, then The other end described in interior axle is placed in the bearing centre hole of one end described in hollow outer shaft, then one end described in interior axle applied downwards Pressure, its other end is penetrated inner chamber, then passed from the bearing centre hole of the hollow outer shaft other end;The interior axle other end is from hollow outer When the bearing centre hole of the axle other end passes, pressure is applied from bottom to top to the bearing of the hollow outer shaft other end, prevents the bearing Because the downward pressure of interior axle disengages it from outer shaft.
In implementation process, the end face of bearing can not only save space with outer shaft end face, and in transmission process In avoid interfering with miscellaneous part;Both ends described in interior axle are arranged in two bearings, so not only make interior outer shaft that phase can occur To rotating, outer shaft has higher axiality in guarantee;And may be such that interior axle support is more firm, transmission is more steady.Interior outer shaft Relative motion can use this sample loading mode, when interior axle is rotated by motor driven, outer shaft can be made not rotate, only by elliptical drive for wheel Outer gear is driven to rotate, so as to export power;When outer shaft is rotated by motor driven, interior axle can be made not rotate, only by ellipse The pinion rotation of the drive wheel different numbers of teeth in addition, so as to export the power with outer shaft different drive ratios, it is seen that the present invention can Realize the transmission of different drive ratios.
