Description

The novel vertical dynamic balancing does not have the needle guard cycloidal reducer
Technical field
The present invention relates to cycloid braking technique field, a kind of novel vertical dynamic balancing does not have the needle guard cycloidal reducer.
Background technique
There is not interruption in SUMITOMO CHEMICAL heavy-duty machine tool Co., Ltd. to the research of cycloidal-pin wheel transmission always, from 69 years 50 types, 94 years 4000 types, to 6000 types in 2000, it is said that the development that reaches 31 years has realized up to 40% lightweight.
After introducing China's sixties from day, very fast just mad domestic speed reducer industry, the cycloidal reducer product has horizontal WX series, vertical LX series, and horizontal WB series, vertical LB series are arranged, and also has the Ministry of Chemical Industry's standard and the standard B of First Machinery Industry Department series.
Discover, have following three problems on SUMITOMO CHEMICAL 6000 types and domestic X, the B series structure:
(A) traditional " pin wheel housing is connected in structure on the body end face with long spiro nail ": because the retarder active force all produces from pin wheel housing, thereby must strengthen pin wheel housing, thickening connecting flange, overstriking long spiro nail, heavy body, heavy body is not with radiating fin to increase weight and manufacture cost greatly, and heat dispersion is poor;
(B) cantilever W output shaft structure, the output shaft cantilever support, thereby axial dimension is long, pin shaft extension end amount of deformation is big.
(C) adopt traditional " band needle guard, two fulcrum needle pin structures ":
(C-1) in " gear pin adds cover to be made to contact with cycloid wheel and be rolling friction, has prolonged this strength member life-span of cycloid wheel " " mechanical design handbook " (second edition) 707 pages.But " gear pin produces bending deflection after bearing cycloidal gear teeth pressure, and bending deflection is crossed ambassador's gear pin and contacted badly with pin gear sleeve, rotates dumb gear pin and the pin gear sleeve surface of contact of easily causing and glues together, and cause cycloid wheel and pin tooth gummed." " 799 pages of Gear Transmission Design handbook and Wang Wenbin " mechanical design handbook " volume 3.17-109 page or leaf; (C-2) splash lubrication oil can't be lubricated several pin teeth in top and needle guard rubbing surface in the retarder;
(C-3) needle pin of two fulcrum needle pin structures must have enough big pin footpath, in addition curtate ratio K for not producing excessive bending deflection 2=R Zr z -1Sin (180/z b) tell us, because needle guard (r has been arranged z) make reduction speed ratio>43 o'clock most of types all must take out tooth, the result who takes out tooth is the bearing capacity drop by half;
Summary of the invention
It is the doubly serial cycloidal reducers of Japanese 6000 type 1.5-2 that the present invention aims at creating bearing capacity, and a kind of novel vertical dynamic balancing does not have the needle guard cycloidal reducer.Zhu Xiaolu " 6 pages of Gear Transmission Design handbook, " 1-12 page or leaf on the gear handbook: cycloid efficiency eta=0.9~0.98 ≈ 0.94, identical with NGW η=0.96 (secondary), 0.94 (three grades), thereby can replace the NGW planetary reducer.The most advanced retarder of technological scheme must possess following key element:
(1) structure advanced person's body because body heavily accounts for 60% of complete machine, and existingly reset valency with machine, yet the structural type of body does not cause gear expert's great attention so far, and this point just can be found out from Japanese 6000 types, domestic X, B series;
(2) axial dimension is short; (3) overload capacity is strong.
Technological scheme is described below:
(A) adopt both ends of the surface the flange circle to be arranged, the vertical thin walled cylinder body of radiating fin arranged outward, its advantage is: have very high mechanical strength, in light weight, perfect heat-dissipating, according to " 7-81 page or leaf on the gear handbook, Cheng Daxian " mechanical design handbook " volume 3.14-411 page or leaf and open the theoretical calculation formula of planetary reducer support (casing) the wall thickness δ that 274 pages of scheduling theory works of exhibition " planetary differential transmission device " propose and be defined as in conjunction with casting material and technology wall thickness: δ~1.5T D 0.25(mm) (T D-Nm);
(B) adopt rigidity cage type W output mechanism: the output shaft disk is connected one with equal load plate with uniform pin, its block bearing places the both sides of escapement, can shorten axial dimension greatly, the device Circular Plate doubles the pin flexural stress between wheel and wheel, reduce the external diameter that the pin diameter can increase capacity eccentric bearing, also can improve the dynamic load rating ability of capacity eccentric bearing;
(C) adopt four wheels to make the rotating mass on the input shaft be in static balancing, dynamic equilibrium state, transmission is more steady;
(D) according to Wang Wenbin " mechanical design handbook " volume 3.174-129 page or leaf: " RV... pin tooth partly is embedded in the pin holes of pin wheel housing, does not have bending deflection basically ", partly burying tooth is to process the pin wheel housing endoporus car of pin-and-hole greatly to D Z-dz+4e+ (0.2-0.4) obtains, and needle pin is not with cover, and half buried via hole opening both sides wedge angle is repaiied blunt, not only improves wedge angle intensity but also be beneficial to oil-feed;
(D-1) needle pin and half buried via hole had both been realized and cycloidal gear teeth rolling engagement movingly, were beneficial to again from half buried via hole and axially extracted out;
(D-2) theoretical calculation shows, the contact stress of needle pin and half buried via hole only is the 6-8% of allowable value, thereby can guarantee that pin wheel housing can use for a long time, and it is lubricated better not to be with needle guard to make, and the single-stage reduction speed ratio needn't be taken out tooth to 144 greatly.Be calculated as follows: [cycloid 6275 retarder parameters] N=62kW, n 1=1000rpm, i=143, T 2=79590Nm (η=0.94), Rz=325, e=1.50, K 1=0.6646, K 2=1.5755, Y 1Max=1.350, b=56mm, needle guard (tooth) radius r z=ρ 1=4.50, half buried via hole radius of curvature ρ 2=4.509 (hole φ=9.018), so: pin-tooth directed force F max=2000T/ (K 1Rz Za)=5154 (N), pin tooth and half buried via hole contact stress: σ Jmax=0.418{FE (ρ 1 -12 -1)/b} 0.5==0.418{5154 * 2.06 * 10 51 -12 -1)/56} 0.5=38.8 (MPa) (be allowable value 6.1%)
(notes) Xu Hao " mechanical design handbook " volume 1.4-289 page or leaf: steel-cast iron [σ H]=633 (MPa);
Beneficial effect: according to SUMITOMO CHEMICAL 6000 types, creativeness of the present invention is:
(1) have advanced thin-walled body and W output mechanism, thus 20-30% in light weight, the short 25-35%. of axial dimension;
(2) the pin tooth is not with cover and is partly buried tooth, thereby bearing capacity is 1.5-2 times of 6000 types;
(3) when running inertial force and moment of inertia complete equilibrium in theory;
