Oil sources is also possible to be exported by oil pump, then observes delivery rate in real time by oil mass viewer, and pass through oil mass
Valve 3 controls delivery rate.
In present invention, it is desirable to the bottom shuttle of fuel feeding is rotating shuttle 7.To improve fuel feeding effect, rotating shuttle 7 has spiral oil charging structure,
Spiral oil charging structure oil suction and can supply rotating shuttle 7 from oil pipe automatically according to the high-speed rotation of rotary shuttle shaft 5.
Spiral oil charging structure includes rotation shuttle seat 6, rotary shuttle shaft 5 and the rotating shuttle 7 being mounted on rotary shuttle shaft 5.It is fixed in rotation shuttle seat 6
There is the axle sleeve 8 being sheathed on outside rotary shuttle shaft 5, there is oil-gap 81 between the inner wall of axle sleeve 8 and the outer wall of rotary shuttle shaft 5, in axle sleeve 8
The upper oriented oil connection 82 for crossing 81 oil transportation of oil-gap of installation.
Rotary shuttle shaft 5 is formed with axial cavity 51 in one end of installation rotating shuttle 7, and the inner end of axial cavity 51 passes through radial oil inlet
Hole 52 is connected to oil-gap 81 is crossed, and the outer end of axial cavity 51 is to 7 fuel feeding of rotating shuttle.The inner wall of axial cavity 51 is formed with rotating shuttle 7
The first spiral oil transportation structure 53 that oil conveys outward from inner end.
When sewing machine works, under 5 high-speed rotation of rotary shuttle shaft, the first spiral oil transportation structure 53 can generate axis during rotation
To driving force, so that oil liquid be conveyed along axial cavity 51 to rotating shuttle 7.
First spiral oil transportation structure 53 can be the spiral groove positioned at 51 inner wall of axial cavity, be also possible to be located at axial
The spiral prominence tooth of 51 inner wall of cavity.
Under 5 high-speed rotation of rotary shuttle shaft, the oil liquid of input axial cavity 51 can be distributed in axial cavity 51 because of centrifugal force
Inner wall, oil liquid are easier to be distributed on the driving of the first spiral oil transportation structure 53 on inner wall.Meanwhile because the first spiral oil transportation knot
Structure 53 is located at the inner wall of axial cavity 51, and the good airproof performance of axial cavity 51 avoids oil liquid from overflowing under the action of the centrifugal force
Risk.
Rotating shuttle 7 has axis mounting portion 7a, and oil liquid is from the port of axial cavity 51 to 7 fuel feeding of rotating shuttle, axis mounting portion 7a and rotation
It is equipped with the first sealing ring 71 between 5 outer wall of shuttle axis, prevents oil liquid from overflowing from junction.
Rotary shuttle shaft 5 is formed with the second spiral oil transportation structure 54 in the outer wall for crossing oil-gap 81.Second spiral oil transportation structure 54 can
To be the spiral groove positioned at 5 outer wall of rotary shuttle shaft, it is also possible to the spiral prominence tooth positioned at 5 outer wall of rotary shuttle shaft.Second spiral oil transportation
Structure 54 is for the oil transportation between oil connection 82 and fuel feed hole 52.It is equipped between 5 outer wall of axle sleeve 8 and rotary shuttle shaft for sealing
Cross the second sealing ring 83 of 81 port of oil-gap.Second sealing ring 83 may be mounted at one end of oil-gap 81, can also pacify
It was mounted in the both ends of oil-gap 81.
In other embodiments, when the distance between oil connection 82 and fuel feed hole 52 are close, oil connection 82 can
With directly 51 oil inside offering of cavity in the axial direction, the second spiral oil transportation structure 54 can be saved.
In main view shown in Fig. 1, when rotary shuttle shaft 5 is rotated counterclockwise with scheming shown direction, the first spiral oil transportation knot
The hand of spiral of structure 53 is left hand direction, plays the role of conveying oil liquid from 5 rear end forward end rotating shuttle 7 of rotary shuttle shaft.Work as rotating shuttle
Axis 5 is when rotating clockwise, and the hand of spiral of the first spiral oil transportation structure 53 is clockwise direction.Second spiral oil transportation structure 54
The hand of spiral is identical as the hand of spiral of the first spiral oil transportation structure 53, utilizes the first spiral oil transportation structure 53 or the second spiral transferring
The rotation driving oil liquid of oily structure 54 axially conveys, to 7 fuel feeding of rotating shuttle.
First spiral oil transportation structure 53 can automatically adjust fuel delivery according to revolving speed.The revolving speed of rotary shuttle shaft 5 is higher, rotating shuttle 7
Need oil mass bigger, while the first spiral oil transportation structure 53 is also bigger to the driving force of oil liquid with the raising of revolving speed, realizes and supplies
The automatic adjustment of oil mass.
Highly preferred embodiment of the present invention has illustrated, and the various change or remodeling made by those of ordinary skill in the art are not
It can depart from the scope of the present invention.
