Description
Technical field
The present invention relates to cycloid reduction technical field, a kind of novel pinwheel exports cycloidal reducer.
Background technique
Dalian University Of Communications teaching inventive innovation " pinwheel output pin swing planetary transmission speed reducer " (ZL200820218490.2) proposes one " pinwheel output pin swing planetary transmission speed reducer that bearing capacity is high, transmission efficiency is high, cost performance is high ", report according to " China Construction Machinery " 2010.10 in addition, this model utility is listed in national natural science fund subsidy project in 2009.
Research finds, this model utility exists following problems: (A) pinwheel needle roller bearing support causes complete machine cost too high in casing, because needle bearing internal diameter is now slightly larger than center diameter of gear pins, for X3 type cycloidal reducer: D
z=140, unit price 555 yuan, export, through looking into as adopted this model utility pinwheel: needle bearing NA4928 (140 × 190 × 50) unit price 864 yuan, a needle bearing cost is higher than complete machine valency; B) traditional freely-supported needle pin structure, thus low bearing capacity.
Research shows that the two large factors restricting cycloid bearing capacity are: (one) overall cycloid wheel pin-and-hole grinding: according to pin-tooth contact stress σ Jmax=(8914/Rz) (YmaxT
2/ b)
0.5, bearing capacity T
2be directly proportional to centre circle of gear pins Dz, the domestic initiation main shaft rotating diameter 1188mm super sized type horizontal inner hole grinding machine of Tianjin speed reducer factory, exactly in order to solve the grinding of X12 type cycloid wheel pin-and-hole.In " mechanical design handbook ", volume 930 pages is loaded with larger four kinds of types: Dz=750 ~ 1200, this just requires that inner hole grinding machine main shaft rotating diameter is up to 1350 ~ 2000.Calculating shows, if Rz=600, b=70, Ymax=1.5, partly bury tooth, and two wheel T
2=300000 (Nm), 4 wheel moments of torsion will up to 600000Nm., and bearing capacity is identical with star-wheel maximum type HJW80D, but is impossible by entirety cycloid wheel of hardening, because can not manufacture large so inner hole grinding machine; (2) gear-box vibration: producing the main factor of vibration is that prior art input shaft capacity eccentric bearing all adopts the in-built eccentric bushing of roller bearing, and radial internal clearance is larger." rolling bearing application manual " 720 pages: " the actual middle (center) bearing radial internal clearance that uses will have influence on bearing load distribution, vibration, noise, friction torque and life-span.”
Summary of the invention the object of the invention is to provide a kind of " novel pinwheel output cycloidal reducer ", in order to replace background technique " pinwheel output pin swing planetary transmission speed reducer " (ZL200820218490.2).
Technological scheme (1) cycloid wheels are cast iron spoke and Bearing Steel wheel rim assembly structure, Simplified flowsheet greatly; (2) adopt two back-to-back combinations of single row conical bearing, radial internal clearance is bordering on zero to eliminate vibration; (3) pin holes on pin wheel housing is half buried via hole.
Beneficial effect: be according to its creativeness of background technique: (1) bearing capacity is high, Maximum Torque T
2=600kNm; (2) low cost of manufacture 35-55%; (3) during running inertial force and moment of inertia complete equilibrium, noise are low in theory.
