Abstract
The invention discloses a multi-point-meshing outer gear speed reducer which comprises a central input shaft, a driving gear, driven gears, an output gear, a central output shaft, an input end machine shell and an output end machine shell. The driving gear is fixed on the central input shaft which is fixed on the input end machine shell through a bearing, the driven gears are fixed on the input end machine shell through a gear shaft and a bearing, and the output gear is fixed on the central output shaft which is fixed on the output end machine shell through a bearing. The multi-point-meshing outer gear speed reducer is characterized in that at least two driven gears are symmetrically distributed along the circumference of the driving gear to be meshed with the driving gear, and a second driven gear different in tooth number is fixed at the other shaft end of each driven gear and meshed with the output gear.
Description
Technical field
The present invention and a kind of gear reduction unit, specifically a kind of multi point engagement external gear speed reducer.
Background technique
At present, traditional two pitch wheels of gear reduction unit are by monolateral tooth transmitting torque, and the moment of torsion transmitting is less.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of multi point engagement external gear speed reducer of transmitting large torque.
In order to solve the problems of the technologies described above, multi point engagement external gear speed reducer of the present invention comprises center input shaft, driving gear, driven gear, output gear, center output shaft, input end casing, output terminal casing, driving gear is fixed on the input shaft of center, center input shaft is fixed on input end casing by bearing, driven gear is also fixed on input end casing by gear shaft and bearing, output gear is fixed on the output shaft of center, center output shaft is fixed on output terminal casing by bearing, it is characterized in that, the at least symmetrical plural driven gear of circumference and driving gear engagement along driving gear, another axle head of driven gear is also fixed the second driven gear of different numbers of teeth, the second driven gear and output gear engagement.
Adopt the design's beneficial effect to be: the gear teeth meshing by a plurality of driven gears from a plurality of orientation and driving gear, thus improved the larger moment of torsion output capability of gear of identical modulus and material.
Accompanying drawing explanation
Fig. 1 is the structural representation of multi point engagement external gear speed reducer of the present invention.
