The motor are rigid jointed with flange to the cap of deceleration box. The pinion gear is shrunk-on the motor shaft and is engaged with two large gears on the crank shaft. The inner gear installed on the link of the crank shaft engages with outer gear on the output shaft. Two ends of output shaft are fitted with bearings. Said device features strong bearing capacity, large drive ratio, smooth operation, reliable property, simple structure, easy making, long service life, small maintenance work and low cost.
Description
The present invention 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.These No. 91230087.6 Chinese patents of existing skill 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 objective of the invention is the characteristics of motor and fixed axis gear transmission, little gear difference planetary driving mechanism and drag link are incorporated into one, a kind of advanced person's electromechanical integration synthetic speed reducing driving device is provided.
The present invention 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, between the connecting rod crank throw bearing is 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, and 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 present invention 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.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the horizontal installation External view of the present invention.
Fig. 3 is the vertical installation External view of the present invention.
Fig. 1 illustrates the biography mode and the structure of synthetic speed reducing driving device and forms: mainly contain motor (1), small gear (2), gearwheel (3), bent axle (4), bearing (5), two connecting rods (6) with internal gear, output shaft (8), external gear (7), bearing (9), (10), casing (11) and case lid (12).
Motor (1) is fixed on casing (11) case lid (12) with flange plate, suit small gear (2) on the transmission shaft of motor (1), small gear (2) and two gearwheels (3) engagement, gearwheel (3) is sleeved on the bent axle (4), connecting rod (6) is 180 ° of phase differences and is bearing on the crank throw, connect with bearing (5) between connecting rod (6) and the crank throw, bent axle (4) is striden by two bearings (10) branch and is installed on the casing, internal gear on the connecting rod (6) and external gear (7) engagement, external gear (7) is sleeved on the output shaft (8), on casing, the other end is bearing on the interior bearing of casing output shaft (8) by two bearing (9) one end bearings.Motor can be contained on the casing or on the case lid during vertical installation.
During work, power is by the small gear (2) on the motor reel (1) input, small gear (2) and gearwheel (3) engagement, and the rotation by gearwheel (3) is rotated parallel and symmetrical two bent axles (4), thereby realizes that the first order slows down; Bent axle (4) is through being contained in the bearing (5) on its crank throw, and driving two connecting rods (6) with internal gear is 180 ° plane motion as phase difference, and external gear (7) engagement on the internal gear of connecting rod (6) and the output shaft (8) realizes second level deceleration.The center line of bent axle (4) equates to the distance of input shaft and output shaft; It is stressed good that the block bearing (10) of bent axle (4) and output shaft (8), (9) divide the both sides of striding gearwheel (3) and connecting rod (6) to form freely supported structure.Horizonally split between casing (11) and case lid (12) during the horizontal installation of retarder; Other each cooperation and point of attachment also are equipped with Sealing, supporting member and key, bolt equijoin spare.Casing (11), case lid (12) subdivision between bearing (9) and external gear (7) are provided with flange on casing (11) or the case lid (12) during the vertical installation of retarder.The connecting rod phase difference is evenly distributed on the bent axle with 360 ° of quantity divided by connecting rod and moves when higher or low when rotating speed.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.
