Description
Technical field
The utility model relates to a kind of two tertiary gear retarders that are used to have only three grades of decelerations of two axles realizations of input and output, belongs to a kind of mechanical transmission.
Background technique
In modern mechanical, a lot of machines all need retarder, and retarder is used in the every field of national economy.The performance of retarder, complexity depend on the structural type of reducing gear to a great extent.With the gear reducer is example, and the velocity ratio of requirement is big more, and structure is just complicated more, and needed step of reduction is just many more, and the corresponding number of axle is also just many more, and the volume of retarder is just big more, and quality is also big more.
The employed retarder of people has gear reducer, turbine and worm retarder, plane table thermoconductivity meter, cycloidal-pin wheel retarder and harmonic speed reducer at present.Gear reducer has the advantage of easy processing simple in structure, but the velocity ratio of gear reducer is less.In gear reducer, its structure is: gear generally is fixedly mounted on the axle with key, the gear engagement on gear on the axle and the adjacent disalignment.The quantity of this mode of structure decision axle must be Duoed 1 than the quantity of gear mesh both step of reduction, if make the retarder of big speed ratio, will increase the quantity of axle when increasing the gear mesh number, the volume of retarder just certainly will increase like this, and its weight has also increased; The mechanical efficiency of turbine and worm retarder is low, and it is high-abrasive material that its turbine needs again, and price is expensive; Plane table thermoconductivity meter, cycloidal-pin wheel retarder and harmonic speed reducer, its complex structure, requirement on machining accuracy height and manufacturing process difficulty are big, and what have also needs special device, so the manufacture cost height.
Obviously, develop and a kind ofly have big speed ratio, and simple in structure, volume is little, lightweight cylinder gear speed reducer has crucial meaning and use value.
Summary of the invention
Proposition of the present utility model aims to provide a kind of two tertiary gear retarders realizing multi-stage speed-reducing and big speed ratio, has overcome little, the bulky problem of gear reducer velocity ratio.
Technical solution of the present utility model is to realize like this;
A kind of two tertiary gear retarders, comprise casing, input shaft, input shaft gear, duplicate gear I, output shaft, output shaft gear, duplicate gear II, it is characterized in that described input shaft is supported in the casing by bearing of input shaft I and bearing of input shaft II, input shaft gear and input shaft are fixedly connected by key, and duplicate gear I is contained on the input shaft by duplicate gear I bearing I and duplicate gear I bearing I I supporting sleeve; Output shaft by
Output shaft bearing I and output shaft bearing II are supported in the casing, and output shaft gear and output shaft are fixedly connected by key, and duplicate gear II is contained on the output shaft by duplicate gear II bearing I and duplicate gear II bearing I I supporting sleeve; The gearwheel engagement of input shaft gear and duplicate gear II, the gearwheel engagement of the small gear of duplicate gear II and duplicate gear I, the small gear of duplicate gear I and output shaft gear engagement.
The axle head of described input shaft is adorned logical lid of input shaft and input shaft end cap respectively; The axle head of output shaft is adorned logical lid of output shaft and output shaft end cap respectively.
Compared with prior art, the utility model has the advantages that conspicuous, show that mainly two tertiary gear retarders have only two axles of input and output, be set with duplicate gear on the axle, can realize that three grades slow down and big speed ratio, when duplicate gear being made equally, be used interchangeably, reduce production costs.
