Abstract
The utility model discloses 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 has also offered mounting hole, and the position being positioned at mounting hole outside part offers a circle circular groove, described mounting hole and connecting through hole are on a straight line, and mounting 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, be less than the diameter of circular groove, the back-up ring for blocking connecting pin is provided with in described groove, by the back-up ring arranged in circular groove, by connecting pin gear in mounting hole and connecting through hole, prevent the responsive to axial force produced during part time job on connecting pin, cause connecting pin to produce displacement to come off, thus cause the problem that part is separated with rotating shaft.
Description
Technical field
The utility model relates to motor device field, particularly relates to a kind of part and machine shaft mounting structure.
Background technique
Some parts need to be fixedly attached on machine shaft, and drive work by machine shaft, traditional part and the means of fixation of machine shaft on machine shaft and part, offer connecting through hole respectively, resilient key is inserted in connecting through hole, machine shaft and part are secured together, this means of fixation drives during part time job can produce axial force at machine shaft, axial force makes part and axle, part and resilient key can produce certain displacement, after long-time, resilient key 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.
Model utility content
The purpose of this utility model is that providing a kind of installs the firm part in location and machine shaft mounting structure.
For reaching this object, the utility model 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 mounting hole, and the position being positioned at mounting hole outside part offers a circle circular groove, described mounting hole and connecting through hole are on a straight line, and mounting 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 mounting 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.
The beneficial effects of the utility model are: described part connecting end is positioned on mounting hole and offers a circle groove, during installation, part is set on machine shaft, and make connecting through hole and mounting hole located on a straight line, cylinder connecting pin hardness being not less than HRC60 inserts in connecting through hole and mounting 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 sectional view of the part that provides of the utility model embodiment and machine shaft mounting structure.
In figure, 1, part; 2, machine shaft; 3, connecting pin; 4, circular groove; 5, circlip.
Embodiment
The technical solution of the utility model 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 mounting hole, described mounting 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 mounting hole and connecting through hole, a circle circular groove 4 is also offered outside mounting 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 mounting 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 mounting hole located on a straight line, straight pin is inserted in connecting through hole and mounting 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 with embodiment, the utility model is illustrated, but the utility model is not limited to above-mentioned size and outward appearance illustration, more should form any restriction of the present utility model.As long as any improvement do the utility model or modification all belong within the protection domain of the utility model claim opinion.
