Belt pulley 1 drives flywheel 2 to rotate by belt 3, and there is belt pulley 1 first surface 10, first surface 10 to be located at skin
1 periphery of belt wheel surround 1 central axes of belt pulley, and there is flywheel 2 second surface 20, second surface 20 to be located at 2 periphery of flywheel, surround
The inner face 30 of 2 central axes of flywheel, belt 3 is posted by first surface 10, second surface 20, and inner face 30 is equipped with several circle muscle side by side
Position 300, first surface 10 is groove face and second surface 20 is smooth surface, and first surface 10 is equipped with several belts circular respectively side by side
Take turns the annular groove 100 of 1 central axes, several muscle positions 300 be embedded in several grooves 100 on 1 groove face of belt pulley and
2 smooth surface of flywheel is pressed on, the design coordinates skin of the inner face 30 with multi-turn muscle position 300 using groove face belt pulley 1, smooth surface flywheel 2
Band 3 uses, and 3 axial position of belt can be limited by the groove 100 of 1 central axes of circular belt pulley of groove face in rotation process,
Inhibit the position in rotation process of belt 3 to fall partially, conducive to overcoming belt 3 to be easy the defect skidded off from smooth surface, and belt 3 can be prevented
Deviate from from the flywheel 2 of smooth surface, meanwhile, the flywheel 2 of smooth surface is in the installation for facilitating belt 3 (if belt pulley 1 and flywheel 2 all use
Groove face does not allow belt 3 easy to install then, and belt 3 is easy to wander off, fall off if belt pulley 1 and flywheel 2 all use smooth surface) while
The condition that belt 3 carries out fine position is provided, though when belt 3 assembles position it is inclined some if can operate after it is in smooth surface enterprising
(3 position of belt is opposite if belt pulley 1 all uses groove face with flywheel 2 is defined dead, skin to the adaptive fine position correction of row
Situation with 3 biasings can not voluntarily finely tune correction so as to cause rotating path to distort), it deacclimatizes, match belt 3 in belt pulley
1 position avoids the biasing of belt 3, rotating path distorts and makes the abrasion of muscle position 300 and distortion damage, raising 3 longevity of belt
Life.So-called smooth surface be for convex-concave surface (such as groove face), smooth surface be without recess (groove 100, pit etc.) and
Protrusion face, relative to groove face smooth surface upper belt 3 be easy lateral sliding.In present embodiment, the formation of first surface 10
There are 7 annular grooves 100, the inner face 30 of corresponding belt 3 to be equipped with 7 circle muscle positions 300, it is clear that quantity is not limited.
Second surface 20 is cylindrical surface, i.e., smooth surface is cylindrical surface, and in a first direction, the inward flange of smooth surface inwardly exceeds slot
The inward flange in face and the outer edge of smooth surface exceed the outer edge of groove face outward, and first direction is parallel to machine shaft 710, belt 3
Width E be less than or equal to groove face width D, smooth surface provide 3 first direction of belt on position adjustment leeway.The inner edge of groove face
Edge is aligned with the inward flange of belt 3, and the outer edge of groove face is aligned with the outer edge of belt 3.In a first direction, the inner edge of smooth surface
Edge inwardly exceed belt 3 inward flange and smooth surface outer edge outward exceed belt 3 outer edge, so design, belt 3 is provided
The leeway that position adjusts on first direction conducive to the edge for avoiding belt 3 from deviating from smooth surface, is also conducive to the outer edge of belt 3 simultaneously
Tensile force is consistent.Width B, A and the B difference that the width A of smooth surface is more than several muscle positions 300 side by side is single muscle position 300
1.4 times to 2.8 times of mean breadth, single 300 mean breadth of the muscle position i.e. width sum divided by muscle of each muscle position 300
The quantity of position 300；The width of one of muscle position 300 is C, the width phase of each muscle position 300 as shown in figure 12 in this implementation
Together, then single 300 mean breadth of muscle position be equal to any one muscle position 300 width.1 central axes of belt pulley and 2 central axes of flywheel
Parallel, the vertical range of 1 central axes of belt pulley and 2 central axes of flywheel is 100 millimeters to 105 millimeters.The outer diameter of belt pulley 1 is
22.4 millimeters, the outer diameter of flywheel 2 is 134 millimeters.1 central axes of belt pulley are overlapped with 710 central axes of machine shaft；Belt 3 with fly
It is in 65 degree to 75 degree angles to take turns 2 two tangent sections, and angle is preferably 67 degree, 69.5 degree or 71 degree.The width D of groove face is less than
The width A of smooth surface.
Flywheel 2 include be located at lateral surface 21 inside and outside it with medial surface 22, connect the outside of smooth surface and lateral surface 21
Fillet surface 23, the inner side chamfering face 24 for connecting smooth surface and medial surface 22.Lateral surface 21 is respectively perpendicular to medial surface 22 in flywheel 2
Axis, the outer diameter of lateral surface 21, the outer diameter of medial surface 22 are less than the diameter of smooth surface, and outside fillet surface 23, inner side chamfering face 24 are
