Abstract
The utility model relates to a speed reducer for driving with a small gear difference. The speed reducer is improved for solving the problems that the speed reducer at the third circle has a large structure and a low input rotating speed; the overload capacity of the hard-surface gear epicyclic speed reducer is weak and the cost is high. The speed reducer uses a double-stage driving structure with multi-axis driving, multi-rings being pressed and multi-phases distributing and multi-gears engaged to form characteristics of a food power distributing, a big driving ratio, a compact structure and a moving balancing, and the W mechanism of the epicyclic transmission is eliminated and all the inner parts are rounded and the production is simple. The speed reducer also achieves the characteristics of a low processing cost/power, a single machine driving ratio of 500, a torquemoment/weight value of 90, a high torquemoment/volume value, a compact structure, big overload ability and a coaxial output. The speed reducer can be used as a universal speed reducer in a new generation to replace the traditional three-circle and more than two level NGW hard-surface gear epicyclic speed reducer and can be used in the important field of mine, metallurgy, elevating transporting, hydropower station, etc.
Description
Affiliated technical field: the purpose of this utility model provides a kind of multi-axis balancing formula inner ring plate little tooth difference speed reducer, is excessive at the three-ring gear reducer structure, and input speed is low; Problem such as the weak and cost height of stiff dough tooth planetary reducer overload capacity and improved.
Background technique: along with the development of modern industrial technology, technical performance and economic indicator to mechanical transmission have proposed more and more higher requirement, under these circumstances, have velocity ratio big, obtained extensive use from the planetary pinion transmission of advantages such as heavy and light, size are little.Planetary drive with small teeth difference is exactly wherein a kind of.Existing few tooth difference transmission has various ways, with regard to the few tooth difference transmission of parallel axes, classifies by the ring flat-plate kind of making eccentric swing, can be divided into board-like transmission of outer shroud and inner ring plate formula transmission two classes.The outer ring plate transmission is with three rings. and single, dicyclo retarder and pendulum ring PS retarder are representative, the inner ring plate transmission is representative with F.P. (FR2571462), the structure of all kinds of retarders differs, but its principle has its general character: promptly having input shaft, to be the parallel axes carry-over moment big, strong and the no special output mechanism distinguishing feature simple in structure of multiple tooth engagement overload capacity has obtained using widely in various low-speed heave-load operating mode situations such as metallurgy, mine, chemical industry.
But the board-like transmission speed reducer of outer shroud still also comes with some shortcomings:
1, be not suitable for running up, because the driving mechanism of three-ring speed reducer own is made up of three blocks of big non-round ring plates, its movement inertia is very huge, and in high speed operation, its unstability can show especially out, and running noise can rise along with the quickening of speed.When serious bearing and axle are produced very big shearing force, reduction of service life:
2, processing cost height: three-ring speed reducer needs relatively more accurate process equipment now, could guarantee the processing of its leggy and the requirement of assembly precision, and the process-cycle also needs long time simultaneously.
3, volume is big, the weight height: because three-ring speed reducer must have two axles parallel to each other, its spatial requirement is big than the hard flank of tooth planetary pinion of homotype, and the waste of material is more serious.
The inner ring plate formula makes moderate progress to above-mentioned deficiency, but because the requirement on machining accuracy of the ring flat-plate of interior three-ring type retarder and eccentric shaft is higher equally, makes cost be difficult to real reduction; And interior dicyclic retarder is subjected to force unbalance when but moving because of it, bumpy motion, and especially when high speed operation, its noise height; Inner ring plate formula retarder in the past in a little ring gear inclusion body, is subjected to structural limitations, and axle and bearing all are difficult to bear bigger load, and when the use condition of large speed ratio and heavy duty, these deficiencies are more outstanding.
For above-mentioned reasons, finally limited the use of parallel axes ring-plate little tooth difference speed reducer.
Summary of the invention: the utility model is that promptly inner ring plate formula (F.P. (FR2571462) or stiff dough tooth planetary reducer) retarder is subjected to ring gear inclusion body structural limitations at the deficiency of existing gear with small teeth difference retarder, is difficult to bear bigger heavy duty load; Outer shroud board-like (traditional three-ring speed reducer) reducer structure is excessive, and input speed is low, and a kind of multi-axis balancing formula inner ring plate little tooth difference speed reducer that provides.Its most fundamental characteristic is to utilize four shaft drive, the Fourth Ring is stressed, four phase distribution, the two-stage drive mechanism that forms multiple tooth engagement in the ring gear is arranged, under the W mechanism characteristics that keeps original big speed ratio of gear with small teeth difference retarder and no Gear Planet Transmission, realized the optimum shunting of the power heavy duty of can loading, compact structure can reduce cost and dynamic balancing can improve taking into account of these characteristics of rotating speed.
The technological scheme that its technical problem that solves the utility model adopts is: adopt four bent axles with four ring flat-plate series operations, respectively be shaped on off-centre such as two sections on four bent axles and turn the footpath, according to motor car engine crank throw phase angle layout principle design, according to four quadratic crank mechanisms respectively last, down, a left side, the orientation layout of right position, the input shaft driving gear drives four eccentric shafts that driven tooth is arranged and rotates (rotation), four eccentric shaft axles divide two groups to drive four transmission ring flat-plates simultaneously and do plane motion, be meshed with the internal tooth of ring gear by the external tooth on the transmission ring flat-plate, output shaft and ring gear link, and are then spread out of by output shaft; If ring gear is motionless, then four external tooth ring flat-plates consist of a rotor with four eccentric shafts, do relative movement (revolution) with ring gear simultaneously, and the supporting frame of rotor both had been that the driving mechanism while also had been the output mechanism of power and motion.
The external tooth ring flat-plate that four uniform thickness are arranged, its four plates radial arrangement symmetry, if be reference point with the eccentric summit of every ring flat-plate, then the eccentric summit of four plates exists respectively: a plate is 0 degree, and two plates are 90 degree, and three plates are 270 degree, and four plates are 180 degree; Axial arranged is one, four plates are one group, two, three plates are another group, become 180 degree to be evenly equipped with the hole of two supporting eccentric shafts in while in each garden, piece ring flat-plate upper edge week with vertical along the via hole that becomes uniform two eccentric shafts of another group of 180 degree garden week with it, be to keep compact structure, but also direct connection of motor shaft, and ring gear can transfixion.
The utility model has adopted the two-stage speed change transmission of the few tooth difference of the first order garden stud wheel and the second level, and unit can form big speed ratio.(first order is 5, and the second level is 100 o'clock, and resultant gear ratio reaches 500).
The beneficial effects of the utility model:, can make little tooth difference speed reducer compact integral structure, big, the stress balance of velocity ratio, stable drive, bearing capacity is big.Noise hangs down little, the stable drive efficient height of temperature rise, and manufacture cost obviously reduces, and has characteristics overload-resistant, that impact is good, the transmission of the most suitable large speed ratio high-speed overload.
