Abstract
The present invention relates to speed reducing gear technology and the super-large speed reducing gear over 1E6 Nm may be manufactured in a medium machine tool. The speed reducing gear of the present invention features that one elastic rod inside the gear seat is used to connect the output shaft, several inner gears and circular cover plate to form one grating and the elastic multi-piece inner gear output assembly has several inner gears corresponding to one outer gear each. The machining and installing errors of the gear pairs are compensated autonomously via the micro deformation of the elastic rod, resulting in uniform load function. Compared with the H-series planetary gear reducing gear in the invention patent, the present invention has 30-40 % reduced size and 25-45 % reduced weight.
Description
The present invention relates to few tooth difference drive technology field, a kind of elasticity is all carried few tooth difference speed reducer, a kind ofly can produce 100*10 under the condition of medium gear cutting machine
4The super large moment of torsion speed reducer of Nm.
Few tooth difference speed reducer is divided into involute less tooth difference speed reducer and cycloid speed reducer two major types according to tooth curve.The involute speed reducer has two kinds of way of outputs: (one) pin axle type, and this moment, ring gear was fixed; (2) ring gear output, this moment, ring gear connected with the output shaft disk.Patent of invention H series star wheel reducer belongs to the latter.Its difference with the prior art only is to change pin into rolling friction by sliding friction, has obviously strengthened difficulty of processing.Because the width of gear is subjected to the restriction of gear shaping machine stroke and the wide increase of tooth alignment error thereupon of tooth that bearing capacity is descended, thereby can only strengthen modulus for the high pulling torque speed reducer, strengthens gear diameter so that strengthen support.Consequently: add gearwheel and bring difficulty to heat treatment; Select for use bigger working machine tool will double to pay processing charges; The weight increase causes the waste of metals resources.
The object of the invention: adopt elasticity all to carry multidisc internal gear engagement pair, relying on increases the secondary quantity of gear engagement, and processing high pulling torque speed reducer is to satisfy the supporting needs of heavy duty industrial on medium-sized lathe.
Embodiment (one) connects one with elastic rod with output shaft disk, multi-disc ring gear and end circle, constitutes cage shape ring gear output block, and support with bearing respectively its both sides; (2) ring gear in () is changed into all carry circle, thereby become the fixing output block of ring gear.
The present invention is when making the high pulling torque speed reducer, and ring gear is not processed the restriction of diameter and gear shaping stroke, as long as increase gear sheet number.This has just opened up a brand-new road for making the especially big bearing capacity speed reducer of height lightweight.The present invention and H series star wheel reducer, SH three-ring gear reducer (once obtaining the national science and technology second prize) reach the table that is compared as follows of the external Z series hard-tooth surface speed reducer of introducing:

2The elasticity of=105 m=12 B=75 design is all carried speed reducer, and its Maximum Torque is up to 125*10
4Nm, the about 12T of weight alleviates 26T nearly than former D125 cement mill.
Below in conjunction with accompanying drawing the present invention is encyclopaedized:
Fig. 1. elasticity is all carried the structure principle chart that few tooth differs from three horizontal speed reducer embodiments one of wheel.
Fig. 2. palisade, six chip elasticity are all carried ring gear output block structure principle chart.
Fig. 3. vertical oil-proof elasticity is all carried few tooth difference speed reducer embodiment's two structure principle chart.
Because fundamental diagram and existing technology are identical, therefore only architecture advances is made description.
With reference to Fig. 1,2 horizontal a kind of elasticity are all carried few tooth difference speed reducer, mainly by input shaft [14], rotary arm bearing [4], external gear, internal gear, output shaft and support constitute, it is characterized in that: elastic rod [6] uniform on the circumference is successively with output shaft [3] disk, ring gear [7] and end circle [12] connect one, constitute cage shape ring gear output block device at support [1] inner chamber, simultaneously for improving the radial load ability of output shaft, adopt two sides of support structures, whole gear pairs are all placed within two supporting points: output shaft is bearing in support [1] endoporus by bearing [2], the end circle is bearing on flange [11] axle journal that connects with end cap [15] by bearing [13], flange [11] is to be used for pin [10] in the device float dish W mechanism, and column sleeve [8] is located floating disc [9].The function of elastic rod [6] is to rely on resiliently deformable to compensate the gear pair machining error automatically.The corresponding external gear [5] of each ring gear.Gear pair has 2～18 pairs, if external gear staggers by 180 ° 2 pairs the time, staggers by 120 ° in the time of 3 pairs, then decides on the gear shaping stroke by 3 groups 2 pairs or 2 groups 3 pairs for 6 pairs, and the rest may be inferred, adopts that gear pair not only improves transmission stability and improves dynamic balancing more than 3 pairs.
Bearing [2] is two, and purpose is to improve output shaft run-out precision and bearing capacity.
The structural type of support [1] is the horizontal support that thin walled cylinder connects side feet, cylinder outer surface has equidistant stiffening rib to connect with two footing and improves the mechanical strength of support greatly, simultaneously, cylindrical portions may only two ends is the fitting surfaces that need processing: the front end endoporus is in order to supporting output shaft bearing [2], the rear end cooperates with end cap [15] seam, the mechanical strength, the two ends coaxality that have not only improved big bearing hole make processing technology become more simple again, are more conducive to add the detection in man-hour;
To big retarding than the time adopt the two-stage transmission: elementaryly use the fixed shaft gear train gear transmission, the few tooth difference of secondary usefulness or with two-stage tooth is poor less.But when the pre-installed bevel-gear sett form right angle of input shaft transmission speed reducer.
When export by pin axle type W mechanism when adopting ring gear to be fixed on the support endoporus, ring gear in the ring gear output block changed into all carry circle [7] and get final product, the rotary arm bearing bearing capacity will descend at this moment.
With reference to Fig. 3 support [1] is vertical support (itself and the difference of horizontal support only are that footing is installed and change disc type into), between output shaft [3] and support front end bearing hole cylindrical, 1～2 oil sealing [16] is arranged, oil sealing places in the oil sealing base [17] that connects one with the output shaft disk, all carries few tooth difference speed reducer thereby constitute vertical elasticity.Vertical type major part is on the polymeric kettle that is applied to industry such as chemistry, chemical industry, food, pharmacy, the stirrer, therefore requires the speed reducer can not leakage of oil.The function of oil sealing [16] just is to prevent the speed reducer leakage of oil, and its principle is: the lubricant oil of support inner chamber can not from bottom to top leak the oil seal circle and then reveal lubricant oil from top to bottom.
Floating disc W mechanism is made up of floating disc [9], pin [10] and column sleeve [8], and floating disc W mechanism lacks most popular output mechanism in the tooth difference speed reducer now.
