Abstract
A long and thin combined shaft structure used in a gearbox is mainly formed by oppositely connecting a first shaft and a second shaft. The joint of the first shaft and the second shaft is sleeved and connected with a spline sleeve with a spline. A screw which can prevent the two shafts from moving in the axial direction is axially inserted and connected between the two ends of the joint of the first shaft and the second shaft. The outer circle of the connected end of the first shaft or the second shaft is positioned by the spline sleeve through h6/H7 in a matched mode. A protruding shoulder used for abutting against the spline sleeve is arranged on one of the first shaft and the second shaft, and a snap spring correspondingly used for limiting movement of the spline sleeve is arranged on the other shaft. The long and thin combined shaft structure has the advantages of being reasonable and compact in structure, convenient to use and install, capable of meeting the use requirement, convenient to produce and manufacture, capable of greatly improving the machining efficiency, and the like.
Description
Technical field
What the present invention relates to is a kind of for the elongated built-up shaft structure in gearbox, belongs 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 object of the invention is to overcome the deficiency that prior art exists, and provide a kind of rational in infrastructure, compact, easy to install and use, usage requirement can be met, be convenient to manufacture, significantly improve work efficiency for the elongated built-up shaft structure in gearbox.
The object of the invention is to have come by following technical solution, 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 present invention 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 invention.
Fig. 2 is the structure for amplifying schematic diagram of an axle of the present invention and two shaft connection places.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1,2, of the present invention 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 present invention 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.
