Abstract

A brushless motor, including a base plate, a sleeve, a stator core, and a bearing, the sleeve is located on the upper surface of the base plate, the stator core is located on the upper surface of the base plate and fits outside the sleeve, the bearing is installed in the sleeve, and the base plate A bottom cover is also installed on the lower surface of the bottom cover, and a plurality of fastening screws are pierced through the periphery of the bottom cover. The fastening screws pass through the bottom plate and the through holes on the sleeve, and are screwed into the threaded holes on the stator core. Compared with the existing brushless motor, the assembly process of the utility model is simple and convenient, which improves the assembly efficiency of the brushless motor, and after assembly, the perpendicularity between the bearing and the bottom plate can be adjusted without disassembly.

Description

A kind of brushless motor

Technical field

The utility model relates to a kind of brushless motor.

Background technology

Present brushless motor comprises base plate, sleeve, bearing and stator core, its installation process is, earlier sleeve is installed on the base plate, bearing places sleeve inner, afterwards stator core is socketed in the outside stationary part that forms brushless motor of sleeve, the brushless motor of this structure, need three cover tools just can finish installation, installation process is comparatively complicated, and labor intensive and activity duration are more, simultaneously, when Bearing Installation, if the bearing run-off the straight, when dead eye can not keep vertical with the plate face of base plate, bearing can't be adjusted to plumbness, need to reinstall after the dismounting.

The utility model content

At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of brushless motor, and its installation process is simple, and the perpendicularity of manual adjusting bearing and base plate.

For achieving the above object, the utility model adopts following technical scheme:

A kind of brushless motor comprises base plate, sleeve, stator core, and bearing, sleeve is positioned at the upper surface of base plate, and stator core is positioned at plate upper surface and is linked in the sleeve outside, Bearing Installation is in sleeve, the lower surface of base plate also is equipped with a bottom, and this bottom periphery cross-under has a plurality of trip bolts, and trip bolt passes base plate, and the through hole on the sleeve, be bolted in the screwed hole on the stator core.

Base plate is provided with an installing hole coaxial with sleeve, and bottom is provided with the projection that equates with trip bolt quantity, and the periphery of installing hole is provided with the recess that embeds for projection, in the plug-in opening that the trip bolt cross-under is offered on projection.

The bottom of sleeve is provided with the lug that is fitted in plate upper surface, and through hole is arranged on the lug.

This brushless motor also includes a support ring, and this support ring is socketed in the sleeve outside and is limited between lug and the stator core.

The beneficial effects of the utility model are:

Than existing brushless motor, the utility model assembling process is simple and convenient, has improved the packaging efficiency of brushless motor, and, after assembling, need not dismounting, just can adjust the perpendicularity of bearing and base plate.

Embodiment

Below, in conjunction with the accompanying drawings and embodiment, the utility model is described further:

As shown in Figure 1, 2, brushless motor of the present utility model comprises base plate 1, sleeve 3, stator core 2, and bearing 4, sleeve 3 is positioned at the upper surface of base plate 1, and stator core 2 is positioned at base plate 1 upper surface and is linked in sleeve 3 outsides, bearing 4 is installed in the sleeve 3, the lower surface of base plate 1 also is equipped with a bottom 5, and these bottom 5 periphery cross-under have a plurality of trip bolts 53, and trip bolt 53 passes base plate 1, and the through hole on the sleeve 3 31, be bolted in the screwed hole 21 on the stator core 2.

Upper surface at bottom 5 is provided with a plurality of projections 52 that equate with trip bolt 53 quantity, base plate 1 is provided with an installing hole 11 coaxial with sleeve 3, the periphery of installing hole 11 is provided with a plurality of recess 12 for projection 52 embeddings, in the plug-in opening 51 that trip bolt 53 cross-under are offered on projection 52; Above-mentioned projection 52 is embedded in the recess 12 one to one, realizes the fixing of bottom 5 and base plate 1 position.In the utility model, three trip bolts 53 can be set, the central shaft of these three trip bolt 53 winding bottoms 5 evenly distributes, and the quantity of above-mentioned projection 52 and recess 12 equally also is three.

The bottom of sleeve 3 is provided with the lug that is fitted in base plate 1 upper surface, and through hole 31 is arranged on the lug; Above-mentioned brushless motor also includes a support ring 6, and this support ring 6 is socketed in sleeve 3 outsides and is limited between lug and the stator core 2.

Above-mentioned brushless motor only needs operating personnel to utilize a screwdriver can finish assembling, and assembling process is simple and convenient, after assembling is finished, check the perpendicularity of bearing 4 and base plate 1 plate face,, adjust certain trip bolt 53 accordingly and get final product if when the axis of bearing 4 and base plate 1 out of plumb.

Those skilled in the art can make other various corresponding changes and deformation, and these all changes and deformation should belong within the protection range of the utility model claim all according to technical scheme described above and design.
