Technical field
The present invention relates generally to the assembly apparatus field of hydraulic system, mainly is a kind of power take-off and gear pump transmission connecting mechanism device.
Background technique
In the hydraulic system of dumping car, gear pump is to connect or the hanger suspending Placement by transmission shaft at present, and such Placement transmission shaft is not easy to reach balance, can produce centrifugal force, cause the knockout press of gear pump to increase, very easily damage, working life is lower, simultaneously, the concentricity of these Placements also is difficult to reach requirement, and very inconvenient during use, the weight of whole hydraulic system is very big, consumable material, cost is higher.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and a kind of power take-off and gear pump transmission connecting mechanism device of easy to use, function admirable is provided.
The present invention solves the technological scheme that its technical problem adopts: this power take-off and gear pump transmission connecting mechanism device, mainly comprise power take-off and gear pump, be in transmission connection by bindiny mechanism between described power take-off and the gear pump, bindiny mechanism comprises connection overcoat, spline connecting sleeve I, spline connecting sleeve II and spline connecting sleeve III, the power take-off splined shaft of power take-off is provided with spline connecting sleeve I, the gear pump splined shaft of gear pump is provided with spline connecting sleeve III, interconnects by spline connecting sleeve II between spline connecting sleeve I and the spline connecting sleeve III; Between power take-off splined shaft and the spline connecting sleeve I, all be connected between spline connecting sleeve I and the spline connecting sleeve II by spline.
Be provided with spring in the described spline connecting sleeve II, the two ends of spring contact with spline connecting sleeve I and spline connecting sleeve III.
Described power take-off and gear pump by screw at the two ends that are connected overcoat.
Described power take-off splined shaft is provided with bearing and seal ring.
Described power take-off and gear pump by screw at the two ends that are connected overcoat.
Described connection puts outward and is provided with drain oil.
The effect that the present invention is useful is: the present invention has improved the life-span of gear pump and transmission part, eliminate the unbalanced potential safety hazard of transmission shaft, oil hydraulic pump connects in self-unloading does not need transmission shaft and gear pump suspension bracket, do not need to change power take-off, connecting body and gear pump directly are installed to get final product, the radial force adjustment of working automatically when having improved power take-off and gear pump coaxality and gear high-pressure work, improve the operating life of gear pump, alleviate original hydraulic system weight 30-40 kilogram, thereby saving raw material, 400-500 unit reduces cost, reduce operating cost more than 100, solved the problem in hydraulic system mounting point and space, energy saving consumption, per car steel use amount reduces 40 kilograms, thereby has reduced the consumption of fuel oil.
