Abstract

The utility model belongs to the field of hydraulic pump technology and discloses a cylinder body used for a hydraulic rotary motor. The cylinder body comprises a cylinder body main body, an internal spline, a plurality of storing grooves and flow channels; the cylinder body main body is of a cylinder-shaped structure having two ends; a through hole penetrating the two ends is arranged in the center of the cylinder body main body; the internal spline is arranged on one end of the through hole; the storing grooves used for matching pistons are arranged in circumferential side of one end of the through hole at an interval along the through hole; the flow channels are respectively arranged at the bottoms of the storing grooves; and the storing grooves and the flow channels penetrate through the two ends of the cylinder body main body. The beneficial effects of the cylinder body are that the internal spline closely cooperating with a main shaft is arranged on the cylinder body so that when a hydraulic walking motor on a main machine is started and stopped, the cylinder body is not liable to swing, so impact generated by inertia can be reduced, stability of the whole machine is achieved and service lifetime of the whole machine is prolonged.

Description

A kind of cylinder body for hydraulic rotary motor
Technical field
The utility model belongs to oil hydraulic pump technical field, relates to a kind of cylinder body for hydraulic rotary motor.
Background technique
Hydraulic pressure convolution motor is a kind of executive component of hydraulic system, and the fluid pressure that it provides oil hydraulic pump can change the mechanical energy (torque and rotational speed) of its output shaft into.In real work, running mechanism is due to the weight reason of itself, on main frame, walk motor with hydraulic pressure can produce very large inertia in starting with in stopping, thereby bring larger impact to hydraulic system, the working life that this can greatly reduce the manoeuvring performance of running mechanism and have a strong impact on complete machine.
Conventionally people just improve to reach and reduce the impact of answering inertia to produce from the accessories such as main shaft, relief valve and swash plate, and people only focus on the basic role of cylinder body, do not improve from reducing the aspect of answering inertia generation to impact.
The utility model is exactly that this improves this shortcoming, improves anti-inertia and produces the performance of impacting.
Model utility content
The purpose of this utility model is: a kind of cylinder body for hydraulic rotary motor is provided, is applied in hydraulic rotary motor, can well coordinate the accessories such as main shaft, relief valve and swash plate, greatly reduce and answer the impact of inertia generation and the working life of improving complete machine.
The technical solution of the utility model is: a kind of cylinder body for hydraulic rotary motor, comprise cylinder body body, also comprise internal spline, tank and runner, cylinder body body is the cylindrical-shaped structure with two ends, cylinder body body center offers the through hole that runs through two ends, and through hole one end is provided with internal spline, and Zhou Ce interval, through hole one end is provided with the several tanks for mating with piston along through hole, a runner is offered in each tank bottom, and each tank and runner run through cylinder body body two ends.
As further improvement of the utility model, Zhou Ce interval, through hole one end is provided with screw along through hole, and screw is placed between through hole and tank.
As further improvement of the utility model, also comprise external splines, the side of cylinder body body is provided with external splines.
As further improvement of the utility model, tank is provided with 6~12.
As further improvement of the utility model, screw is provided with 6~12.
As further improvement of the utility model, tank is provided with 9.
As further improvement of the utility model, screw is provided with 9.
As further improvement of the utility model, cylinder body body is provided with the rounding horn shape flange that is placed in screw top.
The beneficial effects of the utility model are: the internal spline being provided with by cylinder body body, coordinate closely main shaft, on main frame, walk motor with hydraulic pressure is in starting and stopping, the utility model is not easy to swing, thereby can reduce the impact of answering inertia to produce, to reach the steady of entirety, the life-span of improving complete machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is right elevation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage are more clear, in conjunction with the following drawings, it are further described, with reference to Fig. 1 and Fig. 2.
A kind of cylinder body for hydraulic rotary motor, comprise cylinder body body 1, also comprise internal spline 2, tank 3 and runner 4, cylinder body body 1 is for having the cylindrical-shaped structure at two ends, cylinder body body 1 central authorities offer the through hole 11 that runs through two ends, and through hole 11 one end are provided with internal spline 2, and through hole 11 Zhou Ce intervals, one end are provided with the several tanks 3 for mating with piston along through hole 11, a runner 4 is offered in each tank 3 bottoms, and each tank 3 runs through cylinder body body 1 two ends with runner 4.
Through hole 11 Zhou Ce intervals, one end are provided with screw 5 along through hole 11, and screw 5 is placed between through hole 11 and tank 3.Screw 5 is evenly distributed between through hole 11 and tank 3 to stationarity when revolution can be increased, thereby the working life of improving oil hydraulic pump entirety.
Also comprise external splines 6, the side of cylinder body body 1 is provided with external splines 6.
Tank 3 is provided with 6~12.Preferably, tank 3 is provided with 9.
Screw 5 is provided with 6~12.Wherein, screw 5 is provided with 9 and reaches optimum efficiency.
Cylinder body body 1 is provided with the rounding horn shape flange that is placed in screw 5 tops.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned mode of execution.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition,, although used some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
