Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the part of the embodiment of the utility model, rather than all
Embodiment.Embodiment based on the utility model, those of ordinary skill in the art are not making the premise of creative work
Lower obtained all other embodiment, shall fall within the protection scope of the present invention.
See Fig. 1 and 2, there is provided a kind of gear bushing 2, is connected for being adapted with drive gear, including the first cylindrical portion
21 and second cylindrical portion 22, the diameter of the first cylindrical portion 21 be more than the diameter of the second cylindrical portion 22, the first cylindrical portion 21 and second
Cylindrical portion 22 is integrally formed connection, and axial through hole 24, the first circle are offered in the first cylindrical portion 21 and the second cylindrical portion 22
21 outer wall of column portion is connected with outwardly extending spacer 23 on 22 end of the second cylindrical portion.
Wherein, the first cylindrical portion can be used for being connected with the cylindrical hole phase gap of drive gear.
Wherein, the second cylindrical portion can be used for being connected with the cylindrical hole phase gap of drive gear.
Preferably, magnet is additionally provided with spacer.Specifically, magnet can be embedded in spacer.Due to the first circle
Column portion or the second cylindrical portion be connecteds with drive gear for clearance fit, the magnet in spacer can allow bushing and drive gear it
Between be mutually adjacent to, be unlikely to slide so when multiple drive gears are connected or when gear bushing is connected with drive gear.
Wherein, Fig. 3 is seen, the drive gear 1 being connected is adapted with bushing includes base substrate 11, has an axial circular on base substrate 11
Post holes 12, axial cylindrical bore 12 are divided for 122 and second axial cylindrical bore 121 of first axis cylindrical hole, first axis cylindrical hole 122
Connected with the second axial cylindrical bore 121 and the aperture of first axis cylindrical hole 122 be more than the second axial cylindrical bore 121 aperture.
Wherein, base substrate is the ladder circle axis of a cylinder with symmetrical structure.Specifically, ladder circle axis of a cylinder includes the first cylindrical shaft
111st, the second cylindrical shaft 112, the 3rd cylindrical shaft 113, the second cylindrical shaft 112 are coated on the outer wall of the first cylindrical shaft 111, and second
Cylindrical shaft 112 is arranged on the center position of the first cylindrical shaft 111, and the 3rd cylindrical shaft 113 is coated on 112 outer wall of the second cylindrical shaft,
3rd cylindrical shaft 113 is arranged on the center position of the second cylindrical shaft 112, the first cylindrical shaft 111, the second cylindrical shaft 112, the 3rd cylinder
Axis 113 is integrally formed connection.
