Embodiment
The utility model is further described with reference to the accompanying drawings and detailed description:
As shown in FIG. 1 to 3, a kind of rotating shaft for jet graph plotter, including the main shaft 1 positioned at centre, the main shaft 1
Both ends integrally formed with axis 11 and outer shaft 12, the quantity of axis 11 and outer shaft 12 is two.
The outer shaft 12 is located at the outer end of axis 11, the main shaft 1, axis 11 and outer shaft 12 for be arranged concentrically and diameter by
It is decrescence small, the circumferential uniform groove 13 of the outer wall of main shaft 1, cutting 2 is plugged in the groove 13, the both ends of the cutting 2 pass through spiral shell
The baffle ring 3 being connected on axis 11 abuts, and the section of the groove 13 is isosceles trapezoid, section and the phase of groove 13 of the cutting 2
Match somebody with somebody and the upper surface of cutting 2 exceed main shaft 1 outer wall.The upper surface of the cutting 2 is arc, and the upper surface of multiple cuttings 2 is enclosed
Into the circle contour of an interruption.Cutting 2 is made up of polyethylene, and cutting 2 is inserted from the either end of main shaft 1, and the both ends of cutting 2 pass through
Baffle ring 3 fastens, therefore cutting 2 will not loosen, and multiple cuttings 2 are equipped with frictional force when can increase transmission, are not easy to skid,
Small dot bulge can also be set in the upper surface of cutting 2, further lifts frictional force.Wherein the width of baffle ring 3 is without departing from
The length of axle 11, the outer wall of axis 11 set screw thread, and the external diameter of baffle ring 3 is no more than the external diameter of main shaft 1, while to ensure that baffle ring 3 can
Effectively to crimp the end face of cutting 2, therefore the external diameter of baffle ring 3 is greater than the lower surface of cutting 2 between the center line of main shaft 1
Distance.
Be arranged bearing on the outer shaft 12, the bearing include inner ring 4, outer ring 41 and be located at inner ring 4 and outer ring 41 it
Between ball 42, bearing also includes the sealing ring positioned at the both ends of ball 42, and sealing ring is generally fixed on inner ring 4, and this is bearing
Prior art, introduction is no longer developed in details herein.
One end of the bearing abuts the outer face of axis 11, and one end for the inner ring 4 actually abuts the outer of axis 11
End face.
The other end of bearing is locked by the locking nut 6 being screwed onto on abutting outer shaft 12, actually the other end for inner ring 4
Locked by the locking nut 6 being screwed onto on outer shaft 12.The inner face outer rim extension of the locking nut 6, which is provided with, abuts inner ring 4
Support head 61.
Bearing is set in bearing block 5, and the outer end inner wall of the bearing block 5 is provided with the stopper 51 to extend internally, described outer
The outer face of circle 41 abuts stopper 51.So the Internal and external cycle of bearing is reliably fixed, safe and reliable lasting.
The outer face of the outer shaft 12, which is fixed, is crimped with sheath, and the sheath includes round plate 7 and positioned at the outer rim of round plate 7
