Abstract
The utility model provides a special speed reducer for a metallurgical ladle car, which comprises a body, an input shaft, a speed reduction and transmission mechanism and an output shaft, wherein the speed reduction and transmission mechanism adopts four-stage gear transmission, the second stage is a bevel gear, and the first, third and fourth stages are cylindrical gears. The special speed reducer is convenient to install, and saves space; in addition, the requirement on transmission ratio is met; practical problems in the production are solved; and good economic benefit is created.
Description
Technical field
The utility model relates to the speed reducer equipment in the industrial field, particularly relates to the speed reducer of a kind of metallurgical molten steel car special use.
Background technique
At present, the metallurgical molten steel car in the steel mill is as the container and the haulage device of molten steel, more and more obtains using, and in the process of using the molten steel car speed reducer equipment that is absolutely necessary.But traditional speed reducer in use owing to be subjected to the restriction of on-the-spot usage space, usually because driving force is promptly too small inadequately, makes metallurgical molten steel car in use often go wrong, and has a strong impact on ordinary production.
Therefore design and a kind ofly save the space, metallurgical molten steel car special reduction gear easy for installation just becomes the problem of needing solution at present badly.
Summary of the invention
The purpose of this utility model is in order to solve problems of the prior art, a kind of metallurgical molten steel car special reduction gear to be provided, and by rational design, saves the space, and is easy for installation, and satisfies the demand of velocity ratio.
To achieve these goals, the technical solution of the utility model is: propose a kind of metallurgical molten steel car special reduction gear, comprise body, input shaft, reduction gearing mechanism, output shaft, wherein reduction gearing mechanism adopts the level Four gear transmission, the second level is bevel gear, first and third, level Four is cylindrical gears.
The input shaft of above-mentioned speed reducer is placed on left end, adopts vertical drive mechanism.
Input end at described body has the fixed electrical machinery support.
Above-mentioned output shaft is a hollow shaft, the outer tensioner cover of installing of axle.
Above-mentioned level Four gear final stage centre distance is 380mm.
Reduction speed ratio 156.1 is finished in above-mentioned level Four gear transmission.
Power of the present utility model is P1=15KW by output power, and the motor of output speed n1=1000r/min provides.
The utility model is according to on-the-spot use condition, input shaft is placed on left end, adopt vertical drive mechanism, increase electric machine support at input end, guarantee that motor shaft and input shaft are concentric, easy for installation, save the adjustment time, for saving the space and reducing the shortcoming that keyway sum of errors wall is thin, intensity is low, adopted the mode of dress tensioner cover on the output cylindrical.
The beneficial effects of the utility model are: the utility model is easy for installation, saves the space, has satisfied the demand of velocity ratio again, has solved the practical problem in producing, and has created good economic benefit.

Embodiment
Below in conjunction with accompanying drawing, technology contents of the present utility model is further described.
As shown in Figure 1, input shaft 2 of the present utility model is at the left end of body 1, as shown in Figure 2, reduction gearing mechanism of the present utility model adopts the level Four gear transmission, wherein, secondary driving gear 4 is a bevel gear, and one-level driving gear 3, three grades of driving gears 5, level Four driving gears 6 are cylindrical gears.
According to on-the-spot use condition, input shaft 2 is placed on left end, adopt vertical drive mechanism, increase electric machine support at input end, guarantee that motor shaft and input shaft 2 are concentric.
Output shaft 7 in Fig. 2, the hollow shaft endoporus does not have keyway, and the tensioner cover has been installed outside hollow shaft, is used for locking the cooperation of hollow shaft, has reduced hollow shaft bore deformation and the low shortcoming of intensity.
The power of speed reducer body 1 is by input shaft 2 inputs, and its power is P1=15KW by output power, and the motor of output speed n1=1000r/min provides.Through one-level driving gear 3,4, three grades of driving gears 5 of secondary driving gear and level Four driving gear 6, reduction speed ratio 156.1 is finished in the level Four gear transmission altogether, and by output shaft 7 outputs, its output torque reaches 22316Nm, output speed n2=6.4r/min. at last.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
