Compared with the existing three-ring speed reducer, the three-ring speed reducer of the utility model has the advantages of larger output torque and bearing capability, stronger overload capacity, more stable drying, smaller vibration and noise, small size, light weight and easier manufacture.
Description
Technical field
The utility model relates to speed reducer in the field of machining, gear transmission manufacturing equipment, is specifically related to a kind of three ring speed reducer.
Background technique
Existing three-ring speed reducer is compared aspects such as its output torque, bearing capacity, transmission efficiency and is had certain advantage with the common cylinder gear reducer, but owing to still adopt involute gear as inside and outside gear pair transmission, its output torque, bearing capacity, overload capacity, transmission efficiency, transmission stability, vibration and noise all remain further to be improved.
The model utility content
Technical problem to be solved in the utility model provides a kind of three-ring gear reducer, has output torque, bearing capacity is bigger, and overload capacity is stronger, and transmission is more steady, and vibration and noise are littler, and size is little in light weight, makes the characteristics that are more prone to.
For solving the problems of the technologies described above, three-ring gear reducer provided by the utility model, comprise box assembly, input shaft, output shaft, the input shaft ring flat-plate, driving key, described input shaft, the output shaft parallel configuration, respectively by Bearing Installation on described box assembly, three described input shaft ring flat-plates are installed on each described input shaft, described input shaft ring flat-plate connects described output shaft by described driving key respectively, it is characterized in that, each described input shaft ring flat-plate is the inner cycloidal gear ring flat-plate, three eccentric bushings are installed on each described input shaft, eccentric bushing of the corresponding respectively connection of each described inner cycloidal gear ring flat-plate, described driving key is an epicycloidal gear, the epicycloidal tooth of epicycloidal gear engagement on the hypocycloidal tooth of described inner cycloidal gear ring flat-plate and the described output shaft.
As improvement, the utility model also comprises synchronous pinion gear, synchronous gearwheel, described synchronous pinion gear respectively is installed on each described input shaft, and on described output shaft, each described synchronous pinion gear connects by described synchronous gearwheel described synchronous gearwheel by Bearing Installation.
Preferably, described three eccentric bushings are 120 ° of off-centre mutually.
It is fewer differential teeth planetary wheel type of belt drive that technical solutions of the utility model adopt, and its gear engagement motion belongs to dynamic gear train, and its output shaft and input shaft parallel configuration have the feature of parallel axes cylindrical gear reducer again.Three identical inner cycloidal gear ring flat-plates of reason drive an epicycloidal gear output, so be called double cycloid gear three ring flat-plate speed reducers.
The utility model is except having the advantage of planetary reducer and common cylinder gear reducer, and owing to used double cycloid gear auxiliary driving mechanism, compare existing three-ring speed reducer, have output torque, bearing capacity is bigger, overload capacity is stronger, transmission is more steady, vibration and noise are littler, and size is little in light weight, make the advantage that is more prone to, be particularly suitable for the occasion that output torque is big, overload capacity is big, velocity ratio is big and use, obvious especially as use advantage on marine anchor hinge machine.
