In order to solve the problems referred to above, the utility model be the technical scheme is that a kind of hydraulic system, including PTO, shaft coupling, hydraulic test, described shaft coupling connects PTO and hydraulic test, it is characterized in that, described shaft coupling includes the first half a coupler and the second half a coupler, the first described half a coupler includes that power input connects end, the first coupling body, shaft coupling connection end I, and the second described half a coupler includes that shaft coupling connects end the II, second coupling body, hydraulic test connects end；The power input of described first shaft coupling connects end and connects PTO, described shaft coupling connects end I and arranges connection projection, described shaft coupling connects end II and arranges connection groove, and what described shaft coupling connection end I was arranged couples in the connection groove that protruding holding just is arranged on shaft coupling connection end II；Arranging spacing preiection on described connection projection two side, described connection groove madial wall arranges limited impression, the lucky holding of described spacing preiection is in limited impression.

Except above-mentioned improvement, the utility model also optimizes at following aspect:

Described hydraulic test includes hydraulic pump and hydraulic oil container and the fluid pressure line being connected with hydraulic pump, and described hydraulic oil container is arranged on the top of hydraulic pump, and hydraulic pump is connected with hydraulic oil container.

Described connection projection is trapezoidal projection, and described connection groove shapes is and couples the protruding trapezoidal groove matched.

Described couple protruding with couple groove and be provided with wearable elastic pad along the position that its circumferencial direction fits.

Described wearable elastic pad is nylon spacer.

The beneficial effects of the utility model are:

1, a kind of hydraulic system of the utility model have employed shaft coupling as the connecting device connected between PTO and hydraulic test, and shaft coupling overcomes the drawback of existing tradition shaft coupling, spacing preiection and limited impression it is correspondingly arranged respectively in the connection projection and connection groove of composition shaft coupling two half a coupler, the contact area of two half a couplers can be increased, alleviate the hard contact of two half a couplers, it is to avoid cause the generation of serious wear phenomenon.Additionally the utility model also arranges wearable elastic pad at two half a coupler contact surfaces, effectively reduces contact friction, and the use longevity that can be greatly prolonged shaft coupling is bright, and equipment traveling comfort has been effectively ensured.

2, between PTO and the hydraulic test of the current hydraulic means of a kind of hydraulic system of the utility model, the shaft couplings using traditional belt or routine connect more, are susceptible to skid or the problem of shaft coupling serious wear.It has reasonable in design, and contact wear is little, service life length feature.

Detailed description of the invention

For the technical characterstic of this programme can be clearly described, below by a detailed description of the invention, and combine its accompanying drawing, this programme is illustrated.

As Figure 1-5, the utility model one hydraulic system, it is mainly used in providing hydraulic power for hydraulic lifting equipment.This hydraulic system includes PTO 1, shaft coupling 2, hydraulic test 3, the PTO selected in the present embodiment is motor, PTO 1 and hydraulic test 3 are linked together by shaft coupling 2, described hydraulic test 3 includes hydraulic pump 31 and hydraulic oil container 32 and the fluid pressure line being connected with hydraulic pump, described hydraulic oil container 32 is arranged on the top of hydraulic pump 31, and hydraulic pump 31 is connected with hydraulic oil container 32.

Described shaft coupling 2 includes the first half a coupler 21 and the second half a coupler 22, the first described half a coupler 21 includes that power input connects end the 211, first coupling body 212, shaft coupling connects end I 213, and the second described half a coupler 22 includes that shaft coupling connects end the II 221, second coupling body 222, hydraulic test connects end 223.The power input of described first shaft coupling 21 connects end 211 and connects PTO 1, described shaft coupling connects end I 213 and arranges connection protruding 4, described shaft coupling connection end II 221 arranges connection groove 5, and described shaft coupling connects the protruding 4 lucky holdings of connection of end I 213 setting and arranges in connection groove 5 on shaft coupling connection end II 221；Described connection arranges spacing preiection 41 on protruding 4 two sides, and described connection groove 5 madial wall arranges limited impression 51, and the described lucky holding of spacing preiection 41 is in limited impression 51.

Spacing preiection and limited impression it is correspondingly arranged respectively within coupling projection and coupling groove, partly in order to increase the contact area of two half a couplers, so can alleviate two half a couplers due to hard contact, it is to avoid due to the phenomenon generation of the serious wear that hard contact causes；On the other hand, spacing preiection and limited impression match, and can be prevented effectively from operationally two half a couplers and occur the most significantly to misplace,

The described projection 4 that couples is preferably trapezoidal projection, and is set to coupling groove shapes and couples the protruding trapezoidal groove matched.The phenomenon that so can reduce the shaft coupling serious wear that hard contact causes further occurs.

For alleviating contact frictionally damage half a coupler further, it is provided with wearable elastic pad 6 with coupling groove 5 along the position that its circumferencial direction fits in the described projection 4 that couples.Described wearable elastic pad is preferably nylon spacer, it is possible to select have the pad of other material of same performance as an alternative according to actual conditions.

The above is preferred embodiment of the present utility model; for those skilled in the art; on the premise of without departing from the utility model principle, it is also possible to make some improvements and modifications, these improvements and modifications are also regarded as protection domain of the present utility model.
