Abstract
The invention relates to the technical field of speed reducers, in particular to a multitooth meshed driving device for transmitting power by an eccentric bearing, which mainly comprises a planetary wheel, a driving shaft, a tapered roller bearing, eccentric bearings, a cycloidal gear and an output shaft, wherein two eccentric bearings are simultaneously arranged on the driving shaft and the cycloidal gear; and the cycloidal gear and a pin stock form rolling contact. Under the condition that a pin wheel is fixed, the cycloidal gear does epicyclic motion for transmitting the driving to the output shaft by the eccentric bearings. The multitooth meshed driving device has the advantages of scientific design, reasonable structure, high torsional rigidity, driving ratio and motion precision, small return difference and starting inertia, strong impact resistance, high driving efficiency and the like.
Description
Technical field
What the present invention relates to is the speed reducer technical field, is specially a kind of transmission device that passes through the multiple tooth engagement of capacity eccentric bearing transferring power.
Technical background
Existing transmission device is to adopt the RV transmission, the RV transmission overcomes the weakness of the harmonic speed reducer of joint of robot transmission, it is the transmission of movement that harmonic speed reducer passes through the resiliently deformable realization of flexbile gear, cause rigidity not enough, return difference is bigger when making transmitted load, has influenced the Location accuracy and the dynamic characteristic of end effector of robot; And kinematic accuracy also reduces along with service time, and the RV transmission has then that torsional stiffness is big, and velocity ratio is big, moment of torsion density (bearing capacity/volume) height, and the kinematic accuracy height, return difference is little, starts under the inertia strong shock resistance and transmission efficiency advantages of higher.
Summary of the invention
The objective of the invention is to, it is transmission device by the multiple tooth engagement of capacity eccentric bearing transferring power that a kind of transmission device is provided, and has changed the pattern of the eccentric shaft transferring power in the conventional construction.
Technical solution of the present invention: a kind of transmission device that passes through the multiple tooth engagement of capacity eccentric bearing transferring power, mainly comprise planet wheel, transmission shaft, tapered roller bearing, capacity eccentric bearing, cycloid wheel, output shaft, two capacity eccentric bearings are housed on transmission shaft, and capacity eccentric bearing is installed on the cycloid wheel, forming between cycloid wheel and the gear pin rolls contact, owing to pinwheel maintains static, in this case, cycloid crop rotation planetary motion is passed to output shaft with transmission by capacity eccentric bearing;
The uniform endoporus in last three centers of two identical cycloid wheel (3) of 180 ° of layouts of described intersection is as the bearing outer ring of capacity eccentric bearing (14).
The transmission device design science of the multiple tooth engagement of the present invention, rational in infrastructure; Have that torsional stiffness is big, velocity ratio is big, kinematic accuracy is high, return difference is little, start that inertia is little, strong shock resistance and transmission efficiency advantages of higher.
