Technical field
The present invention relates to a kind of two ends output speed reduction gearing, particularly a kind of two ends output speed reduction gearing of cycloidal-pin wheel structure.
Background technique
Three-ring gear reducer and cycloidal planetary gear speed reducer are in conjunction with deriving a lot of new drive devices, and these derive from transmission device and have a lot of common advantages:
1) each transmission shaft all adopts simple beam structure, and each stress is good.
2) pinwheel, the cycloid tooth engagement of pure rolling adopted in multiple tooth engagement simultaneously, engagement position, and driving force operates steadily apart from big.
3) remove the W mechanism of cycloidal planetary gear speed reducer, power transmission line is short, and is simple in structure, the efficient height.
4) number of rotary arm bearing increases, and installing space is unrestricted, can the life-span on request carry out the design of rotary arm bearing.
These structural features make the driving mechanism of derivation have simple in structure, characteristics such as transmission efficiency is high, the transmission power scope is big, velocity ratio is big, simple in structure, specific power height., existing structure influenced the development of product but also existing some problems.
Patent of invention hyperbolic axle double cycloid gear planetary speed reducer (CN201121687Y) is though adopted two double crank mechanisms that are mutually 180 °, the centrifugal force of teething-ring plate is balance mutually, but the centrifugal moment that centrifugal force produces is to two cranks and output shaft and uneven, do not reach dynamic balancing, produce vibrations and impact.Patent of invention three-ring hypocycloid reducer (application publication number CN101813166A) has adopted three crank mechanisms that are mutually 120 °, the centrifugal inertia force of teething-ring plate is balance mutually, centrifugal inertia force produces alternation moment to crankshaft and output shaft, does not also reach dynamic balancing.Synchronously to adopt one or two blocks of balance plates are set on demand in the teething-ring plate one or both sides (can be ring gear to band double crank ring-plate-type pin pendulum retarder (ZL96207312.1), also can be not toothed balance plate) teething-ring plate and balance plate phase difference be 180 °, but also may form unbalanced centrifugal force and centrifugal torque of couple, can not guarantee each dynamic balancing.Because toothed belt has radial force to crankshaft, the structural feature that reaches toothed belt self has also limited the power range of transmitting in addition.
Existing in addition speed reducer can not satisfy the needs that export simultaneously at two ends because the restriction of structure is end output.
