Description

High speed large torque multiple-blade motor
Technical field
The present invention relates to multiple-blade motor more particularly to a kind of high speed large torque multiple-blade 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 specific power big, and output speed is high, and output torque is big, output torque Pulsation is again small, is again face sealing, high speed large torque multiple-blade motor not easy to wear, and can adjusting the speed at whole sealings.
In order to achieve the above object, The technical solution adopted by the invention is as follows: a kind of high speed large torque multiple-blade motor, packet It includes shell, rotor, blade, match oil clot and guide pad, rotor is located at center, and case cover at least has in rotor exterior, shell The shifting block that three pieces are distributed uniformly and circumferentially constitutes sliding slot between two neighboring shifting block, and the rotor sidewall is provided with an annular groove, It is along the circumferential direction uniformly provided with locating slot identical with shifting block quantity in annular groove, a blade, blade are installed on each locating slot It is inserted into sliding slot, makes that there is a shifting block in each cavity, be sealed between shifting block and blade by sealing element, it is two neighboring Blade, ring groove surface, the shifting block between two neighboring blade and a cavity is formed between inner walls;Be provided on rotor with The identical hydraulic fluid port of cavity quantity, hydraulic fluid port are connected with a corresponding cavity, and one end of rotor is connected with oil clot;Outside shell There is wall a dome ring J1, dome ring J1 to be placed in the guide groove of guide pad;The axle center of rotor and the axle center 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 movable vane piece one will be generated Rotation is played, blade pushes shell to rotate around its own axis, and during rotation, shifting block slides between two blades, cavity Volume become larger, when reaching maximum, cavity and high pressure chest are disconnected, then by communicating with oil clot with low pressure chamber, then When continuing rotation, cavity volume is gradually become smaller, by matching oil clot to low pressure chamber oil extraction, until reaching minimum;This completes one A circulation.
Further, be dolioform billiard table A2 that both ends cut out two spherical crowns in parallel in the rotor, billiard table A2 up to Rare three bar grooves B2, respectively billiard table A2, the width of slot B2 and the thickness of blade are identical, and the both ends of billiard table A2 are conical side surface C2 With conical side surface D2, there is slot E2 identical with slot B2 quantity, slot E2 to divide equally conical side surface C2, conical side surface on conical side surface C2 There is slot F2 identical with slot B2 quantity, respectively conical side surface D2, slot E2, slot B2 and slot F2 are sequentially connected logical, and it is fixed to constitute on D2 Position slot;The width of slot E2 and slot F2 are identical as the thickness of blade, there is a hole on conical side surface C2 between two neighboring slot E2 K2 is spherical surface G2 with the face being connected conical side surface C2, is spherical surface H2, spherical surface G2 and spherical surface H2 with the face being connected conical side surface D2 Radius and the centre of sphere it is identical as the radius of shell Internal Spherical Surface A1 and the centre of sphere, the both ends of the surface of rotor are anchor ring I2 and anchor ring Hole L2 corresponding with hole K2 is evenly equipped on J2, anchor ring I2, hole L2 is connected with corresponding hole K2, forms hydraulic fluid port, supplies Oil inlet or oil extraction are used.

Operation working principle of the invention is as follows:
As shown in Figure 1,1 inner wall of shifting block and shell between two neighboring blade 3, ring groove surface, two neighboring blade 3 Between formed a cavity, one shares 9 cavities.
It is located at the cavity of the top as shown in figure 1, wherein 1 annulus K1 of shell is located at Far Left, and at this moment the cavity volume is maximum. And in the lowermost cavity, 1 annulus K1 of shell is located at rightmost, and at this moment the cavity volume is minimum.9 all cavities all with horse The right side reached is communicated with oil clot 4, and some with oil clot 4 with high pressure chest by communicating, and some with oil clot 4 with low pressure chamber by communicating. When a cavity of motor is located at bottom, the volume of the chamber is minimum.At this moment, cavity begin through right side with oil clot 4 It communicates with high pressure chest, and is disconnected with low pressure chamber, when high pressure oil is by entering the cavity with oil clot 4, torque will be generated, pushed Rotor 2 rotates, and rotor 2 is rotated together with movable vane piece 3, and blade 3 pushes shell 1 to rotate around its own axis, makes motor rotation;? In rotation process, the shifting block i.e. annulus K1 that reciprocatingly slides between two blades 3 is slided between two blades 3, the volume of cavity Generating period variation, when rotor 2 is during being screwed into the top by bottom, which communicates with high pressure chest always, by Constantly increase in the cavity volume, high pressure oil constantly enters the cavity, constantly generation torque, rotates motor constantly.When When the cavity goes to the top, volume reaches maximum.At this moment, cavity and high pressure chest disconnect, then by matching oil clot 4 and low pressure chamber It communicates, when being further continued for rotation, which is gradually become smaller, will be by matching oil clot 4 to low pressure chamber oil extraction.When rotor 4 is at this During cavity is by being topmost screwed into the lowermost, which communicates with low pressure chamber always, since the cavity volume constantly reduces, So constantly to low pressure chamber oil extraction, until the cavity is returned to bottom.This completes a circulations.All nine cavities are all There is identical process, then motor will constantly rotate in cycles.
By adjust guide pad 7 tilt angle, that is, 1 interior annular K1 of adjustment housings axis and rotor 2 axis Angle, the revolving speed of motor can be adjusted.
Above-described embodiment is used to illustrate the present invention, rather than limits present aspect, in spirit of the invention and In scope of protection of the claims, to any modifications and changes that present aspect is made, protection scope of the present invention is both fallen within.
