Abstract
The utility model relates to a power drive device, in particular to a hydraulic motor. The hydraulic motor comprises a stator and a rotor, wherein the rotor is positioned at the inner side of the stator and maintained to have a precise rotation fit. The hydraulic motor is characterized in that the outer edge in the stator is provided with an oil duct, the oil duct is communicated with a plurality of uniformly distributed oil distribution holes arranged in the stator, and the side surface of the stator is provided with an oil inlet communicated with the oil duct; the inner side surface of the stator is provided with a plurality of oil outlets, and the oil outlets are connected to the outside of the motor through an internal pipeline; four working cavities with openings at the side parts are uniformly arranged in the rotor; end covers used for sealing the working cavities and preventing blades from slipping in the working cavities are fixed at both ends of the rotor through bolts; and a sealing device is arranged in a narrow gap between the rotor and the stator. The hydraulic motor has the advantages of simple structure, low energy consumption, small vibration, small leakage, practicality and convenience.
Description
(1) technical field
The utility model relates to a kind of Power Drive Unit, particularly a kind of oil hydraulic motor.
(2) background technique
Oil motor is with the drive unit of high-pressure and hydraulic oil as rotating power; Adopt Hydraulic Power Transmission System to utilize a plurality of change discharge capacity oil direct driving rotors to reach Sustainable Control; The oil motor that uses at present is owing to its structural limitations manufacturing process more complicated, and power consumption is high, and leakage rate is big; Vibrations are big, use very dumb.
(3) summary of the invention
The utility model is in order to remedy the deficiency of existing technology, and a kind of simple in structure, practical and convenient, power consumption is low, vibrations are little, seepage is little oil hydraulic motor is provided.
The utility model is realized through following technological scheme:
A kind of oil hydraulic motor; Comprise stator and rotor; Rotor is positioned at stator, and keeps accurate being rotatably assorted, and it is characterized in that: said stator interior outward edge is provided with oil duct; Oil duct is communicated with several equally distributed oil distributing holes that are arranged in the stator, and stator-side surface is provided with the filler opening that is communicated with oil duct; Said stator inner surface is provided with several oil outlets, and oil outlet is connected to the stator outside through internal pipeline; Evenly be provided with the active chamber of four side mouth in the said rotor; Be provided with the seal arrangement of band blade between said rotor and the stator in the narrow and small gap; Said two ends of rotor is fixed with the seal operation chamber and prevents that blade from slipping into the end cap of active chamber through axle.
Said seal arrangement comprises and is arranged at the paired groove of stator inner surface, and inside grooves is connected with through spring and keeps the accurate blade that is slidingly matched, and vane tip closely contacts with rotor outer surface.
The beneficial effect of the utility model is: the hydraulic motor structure of this model utility is simple, and is reasonable in design, practical and convenient, is convenient to regulate control, can be used for being suitable for wide popularization and application in the running of multiple lathe rotating shaft.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the structural representation of the utility model;
Among the figure, 1 stator, 2 rotors, 3 oil ducts, 4 oil distributing holes, 5 filler openings, 6 oil outlets, 7 active chambers, 8,9 springs, 10 blades.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises stator 1 and rotor 2; Rotor 2 is positioned at stator 1; And accurate being rotatably assorted of maintenance; It is characterized in that: said stator 1 inner outward edge is provided with oil duct 3, and oil duct 3 is communicated with several equally distributed oil distributing holes 4 that are arranged in the stator 1, and stator 1 side surface is provided with the filler opening 5 that is communicated with oil duct 3; Said stator 1 inner surface is provided with several oil outlets 6, and oil outlet 6 is connected to stator 1 outside through internal pipeline; Evenly be provided with the active chamber 7 of four side mouth in the said rotor 2; Be provided with the seal arrangement of band blade 10 between said rotor 2 and the stator 1 in the narrow and small gap; Said rotor 2 two ends are fixed with seal operation chamber 7 and prevent that blade 10 from slipping into the end cap of active chamber 7 through axle 8; Said seal arrangement comprises and is arranged at the paired groove of stator 1 internal surface, and inside grooves is connected with through spring 9 and keeps the accurate blade 10 that is slidingly matched, and blade 10 tops contact with rotor 2 intimate.
Adopt the oil hydraulic motor of the utility model,, and keep accurate being rotatably assorted because the gap between stator 1 internal diameter and rotor 2 external diameters is very little; Hydraulic oil is after filler opening 5 gets into oil duct 3 in the time of work, and oil duct 3 is connected with oil distributing hole 4, because oil distributing hole 4 is alternately to connect with active chamber 7; Rotor 2 rotation work chambeies 7 will communicate with any one oil distributing hole 4 wherein; Hydraulic oil will enter into the active chamber 7 that communicates, because rotor 2 external diameters play sealing to other oil distributing hole 4, hydraulic oil can not flow out through other oil distributing holes 4; After hydraulic oil is filled with active chamber 7; Continue to inject and will produce pressure and force rotor 2 disequilibriums to be rotated, the speed of rotation and torque are relevant with the pressure difference between the motor oil outlet with the flow of hydraulic oil, along with the position in the rotation work chamber 7 of rotor 2 will produce displacement; Rotor 2 external diameters will seal this oil distributing hole 4 when moving to the oil distributing hole 4 that breaks away from current connection; And stator 1 internal diameter also carries out temporarily sealing to this active chamber 7, and when this active chamber 7 of rotor 2 turned to oil outlet 6, hydraulic oil just can need all not discharged hydraulic oil through oil outlet 6 pressure releases; Only need a small amount of hydraulic oil to inject when making 7 times tasks of this active chamber, thereby make oil hydraulic motor more energy-conservation.And simultaneously make other active chamber 7 alternately be communicated with acting in succession with oil distributing hole 4 because of the rotation of rotor 2, and so replace the property acting, make rotor 2 lasting rotations.This oil hydraulic motor also is furnished with seepage oil recovery channel, makes work more steady.
