Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is enlarged drawing at A in Fig. 1.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
As shown in Figure 1, 2, a kind of rotating flow distribution motor, including shell 9, the front end of shell 9 are fixedly connected with oil distribution casing seat 1,
Rotation connection rotation oil distribution casing 4 in oil distribution casing seat 1 also sets up fixed oil distribution casing 8 between oil distribution casing seat 4 and shell 9, fixed with oil
Disk 8 is fixedly connected with shell 9, and rotating has 5 rotation distributor ports 400 on oil distribution casing 4, has 5 fixations on fixed oil distribution casing 8
Five oil inlet passages 900 being connected to fixed distributor port are arranged in distributor port 800,9 front end of shell, and rotation distributor port 400, fixation are matched
Oilhole 800 and oil inlet passage 900 correspond.It is rotatablely connected crankshaft 25 in shell 1, is arranged 5 around crankshaft 25 in shell 9
Sliding sleeve 10 is respectively set in a cylinder body installation cavity, the both ends in cylinder body installation cavity, and the both ends rotation of cylinder body 14 is plugged in corresponding
In sliding sleeve 10, the both ends setting of cylinder body 14 is used for the lubricating cylinders hole 1400 of oil inlet lubricating.Cylinder body 14 and oil inlet passage 900 connect
Logical, be slidably connected plunger 16 in cylinder body 14.After sliding sleeve 10, when crankshaft 25 applies peripheral force, this week to plunger 16
When being transferred to cylinder body 14 to power, cylinder body 14 can make slight swing by the axis on sliding sleeve 10 around sliding sleeve 10 to eliminate
The peripheral force.
The crankshaft 25 is eccentric shaft, and bearing 32 is socketed on the eccentric position of crankshaft 25, and bearing 32 is cylinder roller bearing,
32 housing of bearing connects spheric seat 29, and inner end and 29 outer surface of spheric seat of plunger 16 touch, also set up on spheric seat 29 for limiting
The limit assembly of position plunger 16.Specifically, plunger 16 has the plunger lubrication hole 1600 for lubrication, before the inner end of plunger 16
Two sides are touched with 29 outer surface of spheric seat afterwards, towards 16 inner recess of plunger in the middle part of the inner end of plunger 16, avoid connecing with spheric seat 29
Touching abrasion.The limit assembly includes axis limit stop ring 22, disc spring 21 and retainer ring 20.The inner end front and rear sides of the plunger 16
Plunger card slot 1600 is respectively set, retainer ring 20 is embedded in plunger card slot 1600, and spheric seat is respectively set in the rear and front end of spheric seat 29
Card slot 2900, axis are embedded in spheric seat card slot 2900 with limit stop ring 22, and disc spring 21 is set to retainer ring 20 and axis limit stop ring 22
Between.The lower end of plunger 16 can be connected on spheric seat 29 using limit assembly, be that plunger 16 cannot relatively spherical seat 29
Be moved forward and backward, but plunger 16 can relatively spherical seat 29 make the rotation of certain angle, in this way, crankshaft 25 is in rotation,
Since spheric seat 29 can be rotated relative to crankshaft 25, plunger 16 and spheric seat 29 only have very small rotation, and frictional force is very small.
In the present invention, the rear end of the rotation oil distribution casing 4 is sequentially connected driving lever 36, driving lever 36 and crankshaft in a known manner
25 are fixedly connected, and fixed oil distribution casing 8 is sheathed on outside driving lever 36, setting sliding cylinder sleeve 2, rotation between fixed oil distribution casing 8 and driving lever 36
Turn oil distribution casing 4 and the sliding rotation of cylinder sleeve 2 is socketed, such crankshaft 25 can drive rotation oil distribution casing 4 to rotate in rotation.
In the present invention, for tool there are two oil inlet and outlet 100, two oil inlet and outlets 100 both can be on the oil distribution casing seat 1
As oil inlet, and it may be used as oil outlet.
The working principle of the prior art: working media first enters from oil inlet and outlet 100, logical by rotation oil distribution casing 4, oil inlet
Road 900 enters cylinder body 14, and the plunger 16 in cylinder body 14 is made to move reciprocatingly, and makes the rotation of crankshaft 25, and crankshaft 25 drives again simultaneously
Rotate oil distribution casing 4 rotate, wherein rotation oil distribution casing 4 share out the work while rotating medium when, make 5 oil inlet passages successively
Be staggered oil inlet, and the reciprocating motion of plunger 16 is made to generate torque to crankshaft 25, and then rotates crankshaft 25.
Present invention is characterized in that 1, present invention employs the crankshaft 25 of centering type, spheric seat is installed in eccentric part
29, outer surface of the inner end of plunger 16 always with spheric seat 29 touches, and has bearing 32 between spheric seat 29 and crankshaft 25, so that
Spheric seat 29 can be rotated relative to crankshaft 25, thus be avoided that between generation crankshaft 25 and plunger 16 that frictional force is excessive to damage motor
Phenomenon；2, the both ends of cylinder body 14 are installed on sliding sleeve 10 by the present invention, when crankshaft 25 applies peripheral force, the peripheral force to plunger 16
When being transferred to cylinder body 14, cylinder body 14 can make slight swing by the axis on sliding sleeve 10 around sliding sleeve 10 to eliminate this week
Xiang Li.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
