Abstract
The invention discloses a mounting structure of a part and a motor spindle; the motor spindle is provided with a connecting through hole; the part sleeves the motor spindle; the part is also provided with a mounting hole; and the position on the outer side of the part where the mounting hole is located is provided with an annular groove; the mounting hole and the connecting through hole are in the same straight line; and connecting pins for connecting the part and the motor spindle are inserted in the mounting hole and the connecting through hole; the length of the connecting pins is greater than the diameter of the motor spindle and less than the diameter of the annular groove; a check ring for limiting the connecting pin is arranged inside the groove; by the check ring arranged inside the annular groove, the connecting pins are limited inside the mounting hole and the connecting through hole, thereby preventing the axial force generated by the work of the part from being acted on the connecting pins to cause displacement and disengagement of the connecting pins, thus leading to the problem that the part is separated from the spindle.
Description
Technical field
The present invention relates to motor device field, particularly relate to a kind of part and machine shaft mounting structure.
Background technology
Some parts need to be fixedly attached on machine shaft, and drive work by machine shaft, traditional part and the fixed form of machine shaft on machine shaft and part, offer connecting through hole respectively, spring pivot is inserted in connecting through hole, machine shaft and part are secured together, this fixed form drives during part time job can produce axial force at machine shaft, axial force makes part and axle, part and spring pivot can produce certain displacement, after long-time, spring pivot easily comes off, part is caused to be separated with machine shaft, if now motor is still in rotation, probably part is thrown away, cause security incident.
Summary of the invention
A kind of installation is the object of the present invention is to provide to locate firm part and machine shaft mounting structure.
For reaching this object, the present invention by the following technical solutions:
A kind of part and machine shaft mounting structure, described machine shaft offers connecting through hole, described part is enclosed within machine shaft, described part also offers installing hole, and the position being positioned at installing hole outside part offers a circle circular groove, described installing hole and connecting through hole are on a straight line, and installing hole and connecting through hole interpolation have the connecting pin for union piece and machine shaft, the length of described connecting pin is greater than the diameter of machine shaft, is less than the diameter of circular groove, is provided with the back-up ring for blocking connecting pin in described groove.
Further, described connecting pin is straight pin, and the diameter of described straight pin is consistent with the internal diameter of installing hole and connecting through hole.
Further, the hardness of described connecting pin is not less than HRC60.
Further, described back-up ring adopts the circlip be conveniently set in groove.
Beneficial effect of the present invention is: described part link is positioned on installing hole and offers a circle groove, during installation, part is set on machine shaft, and make connecting through hole and installing hole located on a straight line, cylinder connecting pin hardness being not less than HRC60 inserts in connecting through hole and installing hole, union piece and machine shaft, and by being arranged on the circlip in groove, connecting pin is blocked, prevent the axial force produced during driven by motor part time job from connecting pin is departed from, cause part to be separated with machine shaft.
Accompanying drawing explanation
Fig. 1 is the cutaway view of the part that provides of the specific embodiment of the invention and machine shaft mounting structure.
In figure, 1, part; 2, machine shaft; 3, connecting pin; 4, circular groove; 5, circlip.
Embodiment
Technical scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, described part and machine shaft mounting structure comprise part 1 and machine shaft 2, described machine shaft 2 offers connecting through hole, described part 1 is enclosed within machine shaft 2, described part 1 also offers installing hole, described installing hole is opened on the large one end of part 1 internal diameter, the connecting pin 3 for union piece 1 and machine shaft 2 is also inserted with in described installing hole and connecting through hole, a circle circular groove 4 is also offered outside installing hole on described part 1, the length of described connecting pin 3 is greater than the diameter of machine shaft 2, be less than the straight line of circular groove 4, be provided with in described circular groove 4 for blocking connecting pin 3, prevent the back-up ring that connecting pin 3 comes off, described back-up ring adopts the circlip 5 be conveniently set in circular groove 4.
Described connecting pin 3 adopts straight pin, and the diameter of described straight pin is consistent with the internal diameter of installing hole and connecting through hole, and the hardness of described straight pin needs to be greater than HRC60, prevents connecting pin in rotation process from occurring phenomenon of rupture.
During installation, first part 1 is set on machine shaft 2, and make connecting through hole and installing hole located on a straight line, straight pin is inserted in connecting through hole and installing hole, again circlip 5 is set in circular groove 4 and straight pin is blocked, namely complete the installation of part 1 and machine shaft 2.
Below only describe the present invention with embodiment, but the present invention is not limited to above-mentioned size and outward appearance illustration, more should form any restriction of the present invention.As long as any improvement do the present invention or modification all belong within the protection range of the claims in the present invention opinion.
Claims (4)
