Description
Technical field
The present invention relates to a kind of motor, particularly about a kind of motor of being convenient to carry out assembling operation.
Background technology
Existing motor please refer to shown in Figure 1ly as No. 94147553 " motor rotor Motor rotor structure " patent of invention of TaiWan, China application case, this existing motor 9 roughly comprises a housing 91, a stator 92, a rotor 93, a clasp 94 and a collar 95.This housing 91 has a basal wall 911, and this basal wall 911 is provided with a central siphon 912, is provided with a bearing 913 in this central siphon 912; This stator 92 is socketed on the periphery wall of this central siphon 912; This rotor 93 has an axle center 931, and this axle center 931 is in conjunction with this bearing 913, and the periphery wall in this axle center 931 is provided with a retaining ring groove 932; This clasp 94 can form closed ring structure as shown in Figure 2, and this clasp 94 has a centre bore 941, and by these centre bore 941 outward extending several otch 942; 95 tops that are stacked at this clasp 94 of this collar.
Existing motor 9 mainly is to assemble this stator 92, clasp 94 and the collar 95 in advance in regular turn when assembling, and the axle center 931 of this rotor 93 is stretched through behind this collar 95 and the clasp 94, combines with this bearing 913 again; Wherein utilize this clasp 94 to have the design of several otch 942, make this axle center 931 to be forced into and the centre bore 941 of this clasp 94 that stretches through, can snap in smoothly in this retaining ring groove 932 for this clasp 94 by the application of force; Whereby, this existing motor 9 can prevent that effectively this rotor 93 breaks away from this housing 91 by this clasp 94 in the actual operation process.
Yet, referring again to shown in Figure 1, the clasp 94 of aforementioned existing motor 9 mainly is connected to an end face of this bearing 913, and this end face of this bearing 913 only has can be for the lead angle design of these axle center 931 combinations of guiding, and this lead angle still can't provide this clasp 94 enough deformation spaces; Therefore, desire to be forced in the process of centre bore 941 of this clasp 94, will cause this axle center 931 to be difficult for being forced into the centre bore 941 of this clasp 94, and then cause the inconvenience in the assembling when this axle center 931.In addition, when this axle center 931 desires further to be forced into the centre bore 941 of this clasp 94 by force, also because this bearing 913 fails to provide this clasp 94 enough deformation spaces, so this clasp 94 is forced into action by force because of this axle center 931 quite easily, make these centre bore 941 peripheries produce situations such as the damage of breaking, and then influence the effect of holding of buckleing of this clasp 94, cause this clasp 94 effectively to reach and prevent that this rotor 93 breaks away from the function of these housings 91.
Summary of the invention
Main purpose of the present invention provides a kind of motor, and it mainly fails to provide problems such as enough deformation spaces in order to the bearing that solves existing motor.
For reaching aforementioned goal of the invention, technological means that the present invention used and the effect that can reach by this technological means are:
A kind of motor, it comprises a pedestal, a bearing, positioning piece, a rotor and a stator.This pedestal has a central siphon; This bearing is arranged in this central siphon, this bearing has one first end face and one second end face, and be provided with a through hole that runs through this first end face and second end face, the position of adjoining this first end face of this through hole forms a depressed part, this depressed part has one second periphery of the inner hole wall of one first periphery of first end face of adjoining this bearing and adjoining this through hole, and the plane at this first end face place to this second periphery has an axial distance; This keeper is arranged at first end face of this bearing, this keeper has a perforation, the inner hole wall of this perforation radially extends several grooves, respectively form a button between this groove respectively and hold sheet, and this keeper has a radial distance by the inner hole wall of this perforation to the inner hole wall of the through hole of this bearing, and this radial distance is not more than this axial distance; This rotor has a rotation axis, and this rotation axis is in conjunction with the through hole of this bearing, and the periphery wall of this rotation axis forms a stopper slot, and this stopper slot is held sheet for each button of this keeper and stretched into; This stator has an assembly hole to be sheathed on the outer peripheral face of this central siphon.Whereby, can utilize the depressed part of this bearing to provide this keeper enough deformation spaces, promote the assembling convenience and can prevent effects such as this keeper damages in assembling process to reach.
Wherein, first periphery of this bearing to this second periphery has a distance, each groove of this keeper is that starting point is radially extended a predetermined length to form a terminal part respectively towards the outer peripheral edges direction of this keeper with the inner hole wall of this perforation, respectively this groove has a radical length respectively from the inner hole wall of this perforation to this terminal part respectively, and respectively this radical length is not more than the distance of this first periphery to this second periphery.Whereby, make the depressed part of this bearing can provide this keeper more enough deformation spaces, with the more perfect assembling convenience of further lifting.
The terminal part of each groove of this keeper can be between first periphery and second periphery of this bearing, and perhaps respectively the terminal part of this groove more can directly be aligned in first periphery of this bearing.Whereby, hold sheet when each button of this keeper and be subjected to promptly having bigger deflection in the process that this rotation axis urges, make can stretch through the more easily perforation of this keeper of this rotation axis.
The depressed part of this bearing forms an inclination tangent plane or a cancave cambered surface between this first periphery and second periphery.Whereby, make each button of this keeper hold sheet and be subjected to this rotation axis and urge and be bent downwardly when distortion that this depressed part can provide more enough deformation spaces.
One retainer ring is set in the central siphon of described pedestal, and this retainer ring compresses fixes this keeper, makes this keeper can be positioned between this retainer ring and this bearing.Whereby, can prevent effectively that this keeper breaks away from the central siphon of this pedestal, to reach the effect that promotes linking steady character.
In sum, beneficial effect of the present invention is: when this motor is desired to be forced into the perforation of this keeper in the rotation axis of rotor, really can provide this keeper enough deformation spaces by the depressed part of this bearing, therefore, this rotation axis is forced in the perforation of this keeper more easily, to promote the overall package convenience.The more important thing is, because this bearing can be by the design of this depressed part, to provide this keeper enough deformation spaces, so being difficult for causing this perforation periphery because of being forced into by force of this rotation axis, this keeper produces situations such as the damage of breaking, make this keeper can prevent effectively that this rotor breaks away from this pedestal in operation process, and then can guarantee the product quality of motor of the present invention.
