Description
The utility model is the synthetic speed reducing driving device that is used for a kind of electromechanical integration of machinery, belongs to mechanical transmission fields.
Existing drive unit with shaft drive mainly contains cycloidal-pin wheel retarder and NGW plane table thermoconductivity meter.The cycloid wheel of cycloidal-pin wheel retarder be suspended on the output mechanism stressed poor, rigidity is little; And the cycloid wheel diameter restrictions size of planetary bearing, bearing pin, guide, thereby influence its intensity and life-span; Though high-precision cycloid wheel can form protruding the contact with a plurality of pin teeth, the bigger employing Bearing Steel that needs of contact stress.NGW planetary reducer velocity ratio is little, is generally less than 12.5, recommends below 9; Planetary pinion and planetary bearing intensity and life-span are lower, its hardened face gear and planet carrier precision height.In addition, the main driving component of these two kinds of retarders all is included in the gear ring, causes other part failure when the damage of a certain part elder generation will produce chain effect, causes that easily complete machine scraps; Its structure is complicated, each parts can only assemble vertically and be not easy to assembling, inspection and maintenance.No. 91230087.6 Chinese patents of prior art do not possess driving and the two kinds of functions of slowing down, and the power of motor could be passed to the retarder except that need adopt coupling in the use, also motor base will be set; And because of its high speed level gearwheel cantilever configuration, bearing load is big, and shaft extension rigidity is poor, adopts the eccentric bushing part more.The coaxial speed reducer of other form fails to widely apply in practice because of its deficiency is respectively arranged.
The purpose of this utility model is that the characteristics with motor and fixed axis gear transmission, little gear difference planetary driving mechanism and drag link are incorporated into one, and a kind of advanced person's electromechanical integration synthetic speed reducing driving device is provided.
The utility model is realized by following technological scheme: motor is fixed on the reduction case with flange plate, motor axle suspension is propped up in casing, small gear is sleeved on the motor shaft, two gearwheel engagements on small gear and the bent axle, two connecting rods are 180 ° of phase differences and are bearing on the crank throw and between the connecting rod crank throw bearing are installed, loading onto the bent axle branch of gearwheel and connecting rod strides by Bearing Installation on casing, internal gear on the connecting rod is meshed with external gear on the lower velocity shaft, on the external gear suit output shaft, output shaft is installed on the casing by bearing one end, the other end is installed on the interior bearing of casing, and motor shaft and output shaft center line are on same straight line in the scheme.Be parallel to shaft axis during the horizontal installation of the flask joint of retarder, be perpendicular to shaft axis during vertical the installation.During vertical installation, the center line of bent axle and motor shaft can be on same plane or on Different Plane, and motor can be contained on the casing or on the case lid.The quantity of connecting rod can be greater or less than two when higher or low when rotating speed, and its phase difference is 360 ° of quantity divided by connecting rod.All profiles of tooth can be straight-tooth, helical teeth, the herringbone tooths of involute or garden arc.According to the stress difference, all interior external tooths all can make the soft flank of tooth respectively, in hard, the hard flank of tooth.Motor shaft, output shaft, bent axle are parallel to each other can be respectively on Different Plane.
The utility model has following obvious advantage and effect compared with the prior art:
1. the drive unit of motor direct connection formation has reduced coupling, input shaft and bearing, has reduced rate of fault, has saved processing charges, has improved working life.
2. adopt bent axle to avoid eccentric bushing processing, assembling complexity, the weakness of damaging easily during use has improved operational safety and life-span.
3. structurally, the gearwheel of level adopts two supports at a high speed, and bearing load is low, and rigidity is big; Improve stress, thereby improved the bearing capacity of bearing and gear.
4. the quantity of connecting rod, shape and mutual phase difference can make it more economical rationally according to rotating speed and the little variation of load.
5. when adopting horizontal type structure, its flask joint and shaft axis are convenient to assembling and maintenance on same plane.
6. vertical structure has enlarged using scope.
