Description
Technical field
The present invention relates to a kind of gear-box, especially a kind of milling train gear-box that contains high, low speed output.
Background technique
In the process that realizes power-converting, gear-box has been brought into play considerable effect.Along with development of science and technology, people constantly propose new requirement to the conversion of power, and various forms of gear-boxes arise at the historic moment according to different demands.
The gear-box that is used for milling train at present, two output shaft generally all is to wait rotating speed, but, satisfy the technical need that requires the special milling train of different rotating speeds between two output shafts, often need be in the design according to traditional gear arrangement mode transition speed change step by step, if the rotating speed between two output shafts differs more than ten times, must cause the volume of gear-box bigger, need occupy bigger installing space.
Summary of the invention
The objective of the invention is to, when requiring different rotating speeds at existing milling train gear-box between two output shafts, the volume of gear-box is bigger, need occupy the practical problem of bigger installing space, and a kind of new milling train gear-box is provided.
The object of the present invention is achieved like this: a kind of milling train gear-box that contains high, low speed output, comprise casing, input shaft, output shaft, and it is characterized in that:
A) first gear shaft, first output shaft, second gear shaft, second output shaft be arranged in parallel, they by bearings in casing; Input shaft is provided with first gear shaft is vertical, and by bearings in casing;
B) fixedly install a bevel gear wheel by key on first gear shaft, by bearings first hollow gear shaft is arranged, the described bevel gear wheel and first hollow gear shaft lay respectively at the gear both sides in first gear shaft, also fixedly install second driving gear by key on described first hollow gear shaft;
C) fixedly install first output gear by key on first output shaft, second hollow gear shaft is arranged, also fixedly install first driving gear on described second hollow gear shaft by key by bearings;
D) fixedly install second output gear by key on second output shaft;
E) the input shaft end fixedly installs a bevel pinion by key; Bevel gear wheel engagement on the bevel pinion on the input shaft and first gear shaft;
F) gear in first hollow gear shaft and first output gear engagement;
G) gear in second hollow gear shaft and second driving gear engagement; First driving gear simultaneously with first gear shaft and second gear shaft in gear engagement; Gear in second gear shaft also meshes with second output gear.
In the present invention: described first gear shaft, one end passes casing, and fixedly installs flywheel by key.
In the present invention: the speed ratio of described first driving gear and second output gear is 1: 1
In the present invention: the speed ratio of first output shaft is 31.25: 1; The speed ratio of second output shaft is 3: 1.
The invention has the advantages that: because first output shaft is through bevel pinion and bevel gear wheel between the input shaft and first gear shaft, the gear in first gear shaft and first driving gear, the gear in second hollow gear shaft and second driving gear, the gear in second hollow gear shaft and the first output gear level Four are slowed down, and second output shaft is under 1: 1 the prerequisite at the speed ratio of described first driving gear and second output gear, only through bevel pinion and bevel gear wheel between the input shaft and first gear shaft, the gear in first gear shaft and the first driving gear double reduction, (gear in second gear shaft is an idle pulley to turn to back output by second output gear of the gear driven in second gear shaft, do not have chronotropic action), said structure has strengthened the gap of speed ratio between first output shaft and second output shaft; Owing between first output shaft and second output shaft, commutate, realized that second output shaft and first output shaft export in the same way by second gear shaft (idle pulley); Because during slow down in the second level of first output shaft, the third level is slowed down and the fourth stage slows down, be based on all that the associated gear of first gear shaft and first output shaft realizes, make first gear shaft have the effect of transmission shaft, low speed gear axle, transition gear axle concurrently, make first output shaft have transmission shaft, transition gear axle and output shaft concurrently, realized usefulness more than one, structure is very compact; Because an end of first gear shaft stretches out casing, and is furnished with flywheel, can put aside work capacity, makes in the gear-box work more steady.
