Utility model content
Defect and deficiency that the utility model exists in order to solve above-mentioned prior art, provide a kind of assembling more smooth and easy convenience, and to locate automaticity high when assembling, good positioning effect, after assembling, steadiness is good, simultaneously the novel electrical micro-machine end cap of heat radiation and high lubricating effect.
Technical solutions of the utility model: a kind of novel electrical micro-machine end cap, comprise end cap body, be arranged on the electrode hole of end cap body both sides and be arranged on the axis hole at end cap body middle part, described end cap body lower surface is provided with two square projections that coordinate electrode hole, in described square projection, be provided with the pole piece groove that coordinates electrode hole, described end cap body outer ring is provided with two symmetrical location arc cutters, described end cap body downside outer ring is provided with assembling circle, and described assembling circle inner side is provided with two symmetrical assembling C angles.
The setting of square projection in the utility model, makes the stable and convenient more that coordinates of pole piece and end cap, the designs of two arc cutters, and for automation assembling and positioning, and outward appearance is more agile; The setting at assembling circle and assembling C angle, makes the more smooth and easy convenience of its assembling, and after assembling, steadiness is good, makes motor operation sound lighter.
Preferably, described end cap body middle part is provided with the round ring boss that coordinates axis hole, and described round ring boss bottom is provided with motor shaft assembling step.
This kind of structure makes motor shaft more firm and reliable with coordinating of axis hole, and the utility model central axis hole adopts the moulding of quality material fine grinding, makes motor shaft and axis hole contact-making surface more smooth, and frictional force drops to extremely low.
Preferably, described end cap body upper surface is provided with two semi-circular recesses for identifying, and is provided with and strengthens projection between two semi-circular recesses, and described reinforcement projection is provided with two Pulvis Emolliens hot holes.
The setting of semi-circular recesses, not only can arrange mark thereon, can also save to a certain extent material, reduces costs; The setting of Pulvis Emolliens hot hole, makes its radiating effect and lubricant effect better.
Preferably, described end cap body outer ring is provided with assembling and positioning groove, and the position of described assembling and positioning groove is corresponding with the position at assembling C angle.
The setting of assembling and positioning groove, coordinates the assembling and positioning sheet on shell, makes the assembling and positioning of end cap and shell more solid and reliable.
Preferably, each square protruding side is provided with an assembling post, and the height of described assembling post is higher than the height of assembling circle, and lower than the height of square projection.
The setting of square projection in the utility model, makes the stable and convenient more that coordinates of pole piece and end cap, the designs of two arc cutters, and for automation assembling and positioning, and outward appearance is more agile; The setting at assembling circle and assembling C angle, makes the more smooth and easy convenience of its assembling, and after assembling, steadiness is good, and the setting of Pulvis Emolliens hot hole, makes its heat radiation and high lubricating effect simultaneously, makes motor operation sound lighter.
