Abstract
The utility model relates to a multi-point engaging outer gear speed reducer. The speed reducer comprises a center input shaft, a driving gear, driven gears, an output gear, a center output shaft, an input end casing and an output end casing, wherein the driving gear is fixedly arranged on the center input shaft; the center input shaft is fixedly arranged on the input end casing through a bearing; the driven gear is fixedly arranged on the input end casing through a gear shaft and a bearing; the output gear is fixedly arranged on the center output shaft; the center output shaft is fixedly arranged on the output end casing through a bearing. The speed reducer is characterized in that at least two driven gears are symmetrically distributed along the circumference of the driving gear and are engaged with the driving gear; a second driven gear with the different tooth number is fixedly arranged on the other shaft end of each driven gear, and each second driven gear is engaged with the output gear.
Description
Technical field
The utility model 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 problems to be solved in the utility model 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 utility model 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 along driving gear engages with 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 multiple driven gears from multiple orientation and driving gear, thus improved the larger moment of torsion output capability of gear of identical modulus and material.
