Description

A kind of high-performance blade hydraulic motor
Technical field
The present invention relates to multiple-blade motor more particularly to a kind of high-performance blade hydraulic motors.
Background technique
Existing vane motor structure is that a rotor eccentricity is placed in cylinder body, blade radial or with rotor half Diameter is angled to be placed in rotor, and blade is thrown away under the action of spring or oil pressure when work, forms seal chamber with cylinder body. This form vane motor due to be between blade and cylinder body by a contact linear sealing, sealing performance compared with Difference, output torque is lower, in addition generating very big friction between blade and rotor and cylinder body when rotation, causes vane motor Overall wear is fast, and the service life is short, low efficiency.In addition, rotor must have in order to guarantee that blade can pass in and out safely in rotor when rotation Comparable diameter, the volume that is bound in this way is big, and specific power is low, although there is Double-blade type hydraulic motor, due to there was only two panels blade, Output torque pulsation is larger, and output torque also owes big.
Summary of the invention
The object of the present invention is to provide one kind to be both able to achieve that specific power is big, and output torque is big, and output torque pulsation is again small, entirely It is again face sealing, a kind of high-performance blade hydraulic motor not easy to wear, and can adjusting the speed at portion's sealing.
In order to achieve the above object, The technical solution adopted by the invention is as follows: a kind of high-performance blade hydraulic motor, including Shell, blade, matches oil clot, guide pad at rotor, and rotor is located at center, and for case cover in rotor exterior, shell is hemispherical, shell End face extend internally and there is circle an annulus K1, annulus K1 to cross the centre of sphere of shell;Blade is installed on locating slot;It is opened on the rotor Have and be also slidably arranged on sliding slot with the one-to-one sliding slot of locating slot, the blade on locating slot, and passes through sealing element and seal;Phase A cavity is formed between adjacent two blades, ring groove surface, inner walls and annulus K1 side wall, is provided with and cavity number on rotor Identical hydraulic fluid port is measured, a hydraulic fluid port is connected with a cavity, and the both ends of rotor are respectively connected with oil clot;The outer wall of shell has One dome ring J1, dome ring J1 are placed in the guide groove of guide pad;The axis of rotor and the axis of shell are not overlapped;
When the high pressure oil of high pressure chest is by entering cavity with oil clot, torque, drive rotor rotation, rotor band will be generated Movable vane piece and shell rotate together, while shell is rotated around its own axis, and blade on the chute carries out stretching motion, are turning During dynamic, the volume of cavity is become larger, and when reaching maximum, cavity and high pressure chest are disconnected, then by with oil clot with Low pressure chamber communicates, and when being further continued for rotation, cavity volume is gradually become smaller, by matching oil clot to low pressure chamber oil extraction, until reaching minimum; This completes a circulations.
It further, is dolioform billiard table A2 that both ends cut out two spherical crowns in parallel in the rotor, the one of billiard table A2 End is conical side surface C2, and at least three bar groove E2 on conical side surface C2, respectively conical side surface C2, slot E2 are sliding slot;Circular cone side There is a hole K2 on the C2 of face between two neighboring slot E2;It is spherical surface G2, radius and the centre of sphere with the face being connected conical side surface C2 Identical as the radius of shell Internal Spherical Surface A1 and the centre of sphere respectively, an end face of rotor is anchor ring I2, is evenly equipped with thereon and hole K2 phase Corresponding hole L2, hole L2 are connected with corresponding hole K2, form hydraulic fluid port, for for oil inlet or oil extraction.
Further, the shape of the cross section of the slot E2 is successively to be connected by cone plane S2, circular arc P2 and cone plane M2 It connects, cone plane S2 and the outer end for boring plane M2 are respectively connected with a circular arc R 2, and two circular arc Rs 2 are concentric, in each circular arc R 2 Sealing element is installed.
