Abstract
A shaft-holding type speed reducer comprises a speed reducer body, the speed reducer body at least comprises input shafts and output shafts, the output shafts bidirectionally and symmetrically extend to two sides of the speed reducer body, a bearing installation part and a wheel installation part are installed on the outer end portion of each output shaft at each side, each bearing installation is connected with a car body through a bearing, and wheels are directly fixed on the wheel installation parts. The shaft-holding type speed reducer is special for a flat wagon, the output shafts of the speed reducer are driving shafts of the flat wagon, driving wheels, bearing seats and other components are directly installed on the shaft-holding type speed reducer, no coupling and other components are required for transition connection, and the shaft-holding type speed reducer is simple in structure and high in transmission efficiency. A motor is directly installed on a speed reducer base plate, and then is in elastic connection wit the car body through lifting holes in the base plate, so that impulsive load is buffered when the speed reducer is started.
Description
Technical field
The utility model relates to the reductor technical field, the axle hung type reductor that specifically a kind of flatcar is special-purpose.
Background technology
In the engineering goods of walking such as flatcar type, often to use motor and speed reducer, through reductor the speed of motor is reduced to rational rotating speed, and then drives the motion of mechanical equipments such as flatcar.In traditional flatcar, reductor is a transition member, realizes that through reductor power by the transmission of motor to main shaft, that is to say, is the split design-calculated between the output shaft of reductor and the main shaft of traveling gear.
The utility model content
The purpose of the utility model is to provide a kind of axle hung type reductor, and a kind of special reduction gear is provided, and provides a kind of flatcar special-purpose reductor through reductor being carried out again optimal design.
The technical scheme that its technical matters of the utility model solution is taked is: this kind axle hung type reductor; Comprise the reductor body; At least have input shaft and output shaft in the said reductor body, it is characterized in that, described output shaft bi-directional symmetrical extends to the both sides of reductor body; And be respectively bearing installation portion and wheel installation portion at the position, outer end of every side output shaft; Bearing installation portion is connected with car body through bearing, the direct fixing vehicle wheel of wheel installation portion, and bearing installation portion wherein and the wheel installation portion interior external position on output shaft can exchange.
Described bearing installation portion is a stepped shaft, and is provided with the jam nut or the jump ring of fixed type bearing in the outer end of stepped shaft.
Described input shaft bi-directional symmetrical extends to the both sides of reductor body.
Described reductor body is three grades of decelerations.
On the reductor body, increase the base plate of an installation motor, also have on the said base plate and be used for and car body bonded assembly hole for hoist.
The beneficial effect of the utility model is: this axle hung type reductor is the flatcar special reduction gear; The output shaft of reductor is the axle drive shaft of flatcar, and assemblies such as direct mount adhesion wheel, bearing seat need not parts such as coupler and carry out transition and connect; Simple in structure, driving efficiency is high; Motor is directly installed on the reductor base plate, is connected the impact load when the available buffer reductor starts again with car body elasticity through the hole for hoist on the base plate.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the birds-eye view of the utility model;
Among the figure: 1 reductor body, 2 output shafts, 21 bearing installation portions, 22 wheel installation portions, 3 input shafts, 4 bearings, 5 wheels, 6 base plates, 61 holes for hoist.
The specific embodiment
Like Fig. 1, shown in Figure 2, this kind axle hung type reductor comprises reductor body 1, is three grades of decelerations, twin shaft input and twin shaft output.
In present case, input shaft 3 bi-directional symmetrical extend to the both sides of reductor body, are the twin shaft input.Certainly, also can import by single shaft, also can play same technique effect.
The output shaft of reductor is the axle drive shaft of flatcar, and assemblies such as direct mount adhesion wheel, bearing seat need not parts connections such as coupler, and are simple in structure, and driving efficiency is high; Motor is directly installed on the reductor base plate, is connected the impact load when the available buffer reductor starts with car body elasticity through the hole for hoist on the base plate.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
Claims (5)
1. axle hung type reductor; Comprise the reductor body, have input shaft and output shaft at least in the said reductor body, it is characterized in that; Described output shaft bi-directional symmetrical extends to the both sides of reductor body; And be respectively bearing installation portion and wheel installation portion at the position, outer end of every side output shaft, bearing installation portion is connected the direct fixing vehicle wheel of wheel installation portion through bearing with car body.
2. axle hung type reductor according to claim 1 is characterized in that, described bearing installation portion is a stepped shaft, and is provided with the jam nut or the jump ring of fixed type bearing in the outer end of stepped shaft.
