Abstract

The utility model relates to a gear assembly, in particular to an easily-transmitting two-shaft assembly of a gearbox of a loader, and mainly aims at solving the technical problems that a transmission wheel adopted by a gearbox in the prior art is complex in structure, incapable of realizing transmission unless a plurality of gears are adopted, not easy to assemble, low in transmission efficiency, high in production cost, poor in strength, short in service life, and the like. The two-shaft assembly comprises a middle input shaft. An outer spline is arranged at one end of the middle input shaft. An inner ring cam is connected on the middle input shaft through a connecting piece. An outer ring gear is arranged outside the inner ring cam. Ratchets are arranged on the outer surface of the inner ring cam. A rolling column is arranged inside each ratchet. A spring and a spring seat are arranged on the inner ring cam. The spring seat abuts against the rolling column.

Description

Loading machine gearbox two axle assemblies of easy transmission
Technical field
The utility model relates to a kind of gear assembly, especially relates to a kind of loading machine gearbox two axle assemblies of easy transmission.
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 structure of the driving mechanism that this gearbox adopts is comparatively complicated, needs to adopt more part 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 loading machine gearbox two axle assemblies of easy transmission, it mainly is that to solve the structure of the driving mechanism that the existing in prior technology gearbox adopts comparatively complicated, need to adopt more part 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:
Loading machine gearbox two axle assemblies of easy transmission of the present utility model, input shaft in the middle of comprising, an end of input shaft is provided with external splines in the middle of described, be connected with interior ring cam by link on the middle input shaft, interior ring cam is equipped with outer ring gear outward, and the outer surface of interior ring cam is provided with ratchet, is provided with roller in the ratchet, interior ring cam is provided with spring, spring seat, and spring seat withstands on the roller.Outer ring gear can rotate at interior ring cam, because the ratchet of interior ring cam tilts to a direction, so outer ring gear can only be toward a direction rotation, and when reverse, roller can by spring, spring seat location firmly can't move, thereby guarantee transmission efficiency.Link can be bolt.
As preferably, be provided with first rolling bearing, second rolling bearing between described middle input shaft and the outer ring gear, be provided with separation sleeve between first rolling bearing and second rolling bearing.First rolling bearing, second rolling bearing can make things convenient for outer ring gear to rotate around middle input shaft.
As preferably, described outer ring gear is provided with oil duct.Can inject lubricant oil in the oil duct.
As preferably, described in the middle of the axle journal place of input shaft be provided with the 3rd bearing.Input shaft was fitted into behind the gearbox more smooth and easy rotationally in the middle of the 3rd bearing can make.
Therefore, the utility model is assembled together middle input shaft, interior ring cam, outer ring gear, and outer ring gear can one-way rotation, make its structure comparatively compact, cost of production is lower, and assembling is comparatively easy, intensity is higher, and transmission efficiency is better, and is simple and reasonable for structure.
