Description
Technical field
The utility model relates to technical field of transmission machinery, especially a kind of supporting mass of heavy speed reducer.
Background technique
At present, existing speed reducer drive structure generally comprises supporting mass, transmission shaft and driving gear, usually adopts key pin to carry out being connected and transmitting torque between transmission shaft with driving gear.For large-scale or heavy speed reducer because the moment transmitted is very large, if adopt a key pin to carry out connecting, there will be driving torque imbalance, instability, problem that transmission efficiency is low, and the transmission part of speed reducer is fragile, cause reduce the working life of speed reducer, reliability reduces.
Model utility content
The purpose of this utility model is to provide the higher heavy speed reducer supporting mass of a kind of transmission efficiency, and this transmission shaft directly arranges gear at axle head and forms overall structure, the equalising torque of transmission, stable.
The purpose of this utility model is achieved by the following technical solution:
Heavy speed reducer supporting mass, comprises housing and transmission shaft, and transmission shaft to be located in housing and to be connected with housing by bearing and to fix, and one end of described transmission shaft is provided with gear I, and the other end is provided with gear II, and described gear I and transmission shaft are connected to form overall structure; Described gear II to be connected with transmission shaft by key pin and to fix; The inner side of described gear I is provided with bearing I, and the inner side of described gear II is provided with bearing II.
As optimal technical scheme of the present utility model, described bearing I is tapered roller bearing, and bearing II is selfaligning roller bearing.
As optimal technical scheme of the present utility model, the inner side of described bearing I is provided with oil sealing I, the outside of bearing I be provided with successively lock washer and and cap; The outside of described bearing II is provided with bearing cap, is provided with oil sealing II between bearing cap and bearing II.
As optimal technical scheme of the present utility model, the end of described gear II is provided with hubcap.
As optimal technical scheme of the present utility model, described gear II to be connected with transmission shaft by being distributed on three key pins on transmission shaft excircle and fixing.The material of described transmission shaft is 42CrMo, and the material of described housing is Ordinary Steel, cast iron or cast steel.
The beneficial effects of the utility model are: relative to prior art, an axle head of the utility model transmission shaft directly arranges gear and forms overall structure, to be connected with gear at the other end of transmission shaft by being distributed on three key pins on axle excircle and fixing, the transmission efficiency of whole supporting mass improved, the moment of transmission balances more, stablize.The utility model is applicable to large-scale, heavy speed reducer or other heavy machinery.
