Abstract
For the elongated built-up shaft structure in gearbox, it forms primarily of an axle and two axle relative bondings, and a described axle and the connecting part of two axles are socketed with the spline housing of band spline joint; Axially a screw rod that can prevent diaxon from moving axially is plugged with between the two ends of a described axle and two axle connecting parts; Connect end cylindrical and the spline housing of a described axle or two axles are coordinated by h6/H7 locates; An axle in a described axle and two axles being provided with the convex shoulder be close to for spline housing, another root axle being provided with the corresponding jump ring for limiting spline housing movement; It has rational in infrastructure, compact, easy to install and use, can meet usage requirement, is convenient to manufacture, and significantly improves the features such as work efficiency.
Description
Technical field
The utility model relates to a kind of for the elongated built-up shaft structure in gearbox, belong to construction machinery gear box technical field.
Background technique
In existing gearbox designs, have because of restrictions such as overall structures, the bearings at both ends span of axle is large, thin and grow (length to diameter ratio is 1:22) when design axle, centre is also with gear, band rectangular spline, and this all brings difficulty to the processing, assembling etc. of part.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of rational in infrastructure, compact, easy to install and use, can meet usage requirement, be convenient to manufacture, significantly improve work efficiency for the elongated built-up shaft structure in gearbox.
The purpose of this utility model has been come by following technical solution, and a kind of for the elongated built-up shaft structure in gearbox, it forms primarily of an axle and two axle relative bondings, and a described axle and the connecting part of two axles are socketed with the spline housing of band spline joint; Axially a screw rod that can prevent diaxon from moving axially is plugged with between the two ends of a described axle and two axle connecting parts.
Connect end cylindrical and the spline housing of a described axle or two axles are coordinated by h6/H7 locates; An axle in a described axle and two axles being provided with the convex shoulder be close to for spline housing, another root axle being provided with the corresponding jump ring for limiting spline housing movement.
The utility model has rational in infrastructure, compact, easy to install and use, can meet usage requirement, is convenient to manufacture, and significantly improves the features such as work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram of an axle described in the utility model and two shaft connection places.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2, described in the utility model a kind of for the elongated built-up shaft structure in gearbox, it forms primarily of an axle 1 and two axle 2 relative bondings, and a described axle 1 and the connecting part of two axles 2 are socketed with the spline housing 3 of band spline joint; Axially a screw rod 4 that can prevent diaxon from moving axially is plugged with between a described axle 1 and the two ends of two axle 2 connecting parts.
Connect end cylindrical and the spline housing 3 of a described axle 1 or two axles 2 are coordinated by h6/H7 locates; An axle in a described axle 1 and two axles 2 being provided with the convex shoulder 5 be close to for spline housing 3, another root axle being provided with the corresponding jump ring 6 for limiting spline housing 3 movement.
Elongated built-up shaft described in Fig. 1 can fixedly mount multiple gear 7, spacer 8, bearing 9 etc.
The utility model is by being divided into two, left and right by slender axles, and realize connecting by spline width and shaft hole matching, wherein an axle and two shaft connection places adopt spline, by spline housing torsion pass, two ends prevent axle from moving axially by screw rod, one axle 1 place cylindrical and spline housing 3 are coordinated by h6/H7 locates, and ensures that the shaft shoulder 5 and jump ring 6 limit spline housing 3 and move with one heart.
