Abstract
The utility model relates to a speed-changing box of a loading machine, in particular relates to a special output shaft for a speed-changing box of an easily-mounted loading machine. The output shaft mainly aims at solving the technical problems that the transmission shaft adopted by the speed-changing box in the prior art is complicated in structure, transmission can be realized only by adopting a plurality of parts, the mounting is difficult, the transmission efficiency is lower, the production cost is higher, the strength is poorer, the service life is shorter and the like. The output shaft comprises an output shaft body, a middle spline is arranged in the middle of the output shaft body, end splines are arranged at two ends of the output shaft body, and two ends of the output shaft body are respectively connected with a threaded head.
Description
Technical field
The utility model relates to a kind of loading machine gearbox, especially relates to a kind of special-purpose output shaft of loading machine gearbox of easy installation.
Background technique
Gearbox is one of important transmission part of loader, speed and moment of torsion that it is responsible for motor is transmitted pass to whole transmission system, change the velocity ratio between motor and the wheel, realize advancing and the backward gear manipulation of loader, and the power of traveling gear is given in the situation incision dig that can be implemented in engine running, with the needs that adapt to the loader operation and travel, be convenient to starting and the parking safety of motor.Loading machine gearbox structural type is based on planetary hydraulic power gear shift.Chinese patent discloses a kind of loading machine gearbox (notice of authorization number: CN 201568536 U), it comprises casing and variable-speed shaft, one runs through casing, one in the casing is provided with a shaftgear, the outer two ends of upper box are respectively arranged with prominent unit, a side of one is provided with oil pump, casing is provided with two, three, four and five, two are provided with and normal two commonly engaged gears that mesh of a shaftgear, two middle parts are provided with sliding sleeve, sliding sleeve is provided with bearing pin, be respectively arranged with counter gear on two of the sliding sleeve both sides, reversing clutch and just changeing gear, just changeing clutch, three high gears that just changeing gear and three last settings often mesh, also be provided with three low speed gears on three, four reverse gears engagements on counter gear and four, four are provided with four shifting slide gears, four shifting slide gears are by slippage action and three low speed gears, three arbitrary engagements of high gear, four four commonly engaged gears that go up to arrange often mesh with five shaftgears on five, and five two ends are provided with prominent first; Two two ends are respectively arranged with counter-rotating oil cylinder and just changeing oil cylinder, the counter-rotating oil cylinder with just change oil cylinder and be connected with bearing pin on the sliding sleeve by plunger, reverse oil cylinder with just change oil cylinder and be connected with selector valve, selector valve is connected with the walking control valve with throttle.But the transmission shaft structure that this gearbox adopts is comparatively complicated, needs to adopt a plurality of parts could realize transmission, installs comparatively difficultly, and transmission efficiency is lower, and cost of production is higher, and intensity is relatively poor, and working life is shorter.
The model utility content
The utility model provides a kind of special-purpose output shaft of loading machine gearbox of easy installation, it mainly is that to solve the transmission shaft structure that the existing in prior technology gearbox adopts comparatively complicated, need to adopt a plurality of parts could realize transmission, install comparatively difficult, transmission efficiency is lower, cost of production is higher, and intensity is relatively poor, the technical problem that working life is short etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The special-purpose output shaft of the loading machine gearbox of easy installation of the present utility model, comprise the output shaft body, the middle part of described output shaft body is provided with the middle part spline, and the two ends of output shaft body are respectively equipped with the end spline, and the two ends of output shaft body connect a thread head respectively.Middle part spline and two end splines are integrated on the output shaft body, make transmission efficiency higher.The case-carbonizing of spline is hardened, carburized layer depth 0.8-1.2mm, surface hardness HRC56-62, core hardness HRC30-45.
As preferably, have groove on the section of described thread head.Can relatively easily output shaft be connected with other parts with groove by screw thread.
As preferably, the output shaft body at spline two ends, described middle part is provided with bulge loop.By the bulge loop location, not only can strengthen the intensity of whole output shaft, output shaft comparatively accurately is encased in the gearbox.
Therefore, the utility model is integrated in middle part spline and two end splines on the output shaft body, makes its structure comparatively compact, and cost of production is lower, and assembling is comparatively easy, and intensity is higher, and transmission efficiency is better, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
The A of accompanying drawing 2 Fig. 1 is to structural representation.
Component, position and numbering among the figure: output shaft body 1, middle part spline 2, end spline 3, thread head 4, groove 5, bulge loop 6.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the special-purpose output shaft of the loading machine gearbox of the easy installation of this example, as Fig. 1, Fig. 2, comprise output shaft body 1, the middle part of output shaft body is provided with middle part spline 2, the two ends of output shaft body are respectively equipped with end spline 3, and the two ends of output shaft body connect a thread head 4 respectively.Have groove 5 on the section of thread head.The output shaft body 1 at spline two ends, middle part is provided with bulge loop 6.
During use, it is encased in the loading machine gearbox gets final product.
The above only is specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
