Abstract
The invention provides an outer slip ring high speed coiling motor to solve problems that a present coiling motor slip ring is placed in a machine base, thus rotor body balance is not easy to operate, carbon brush replacement is difficult, a wind path of a slip ring chamber is complex, powdered carbon is not easy to collect and carbon brush vibrates at a high rotating speed. The outer slip ring high speed coiling motor employs a one-piece slip ring which is placed outside a machine base, a slip ring chamber and the machine base are separated, and a motor body wind path is simplified. A brush rod is fixed on the slip ring chamber, and the slip ring chamber the brush rod can be assembled and disassembled integrally to facilitate carbon brush replacement, slip ring maintenance and subsequent rotor dynamic balance. A slip ring chamber top is provided with an independent cooling blower and an integrating wind device, and a slip ring cooling effect is good. The brush rod is fixed at two ends, and vibration is difficult to generate at a high rotating speed. A slip ring chamber bottom is provided with an arc plate, and powdered carbon collection and cleaning are facilitated.
Description
Technical field
The present invention relates to high speed coiling electric motor structure, be specifically related to a kind of outer slip ring high speed coiling electric motor structure.
Background technology
The structure of slip ring high speed coiling electric motor is as shown in Figure 1 in existing; Slip ring 102 places support 101 inside, receives spatial constraints, exists rotor dynamic balancing not easy to operate; Carbon brush is changed and carbon dust is collected difficulty; Slip ring is problem such as easy care not, and brush holder support 103 adopts an end to fix, and is prone to produce vibration during high rotating speed.Need a kind of new electric machine structure of design, address these problems.
Summary of the invention
Place base inner and the above-mentioned variety of issue that produces to the slip ring of slip ring high speed coiling electric motor in existing, the applicant improves through research, and a kind of outer slip ring high speed coiling electric motor is provided, and slip ring is shifted out the support inner chamber.
Technical scheme of the present invention is following:
A kind of outer slip ring high speed coiling electric motor; Comprise support, between base outer, support and non-shaft stretching end bearing, the slip ring chamber is set, it is indoor that slip ring is installed in said slip ring; The top of slip ring chamber is provided with cooling blower; The corresponding said cooling blower air outlet of slip ring chamber interior place is provided with wind-drive device, and the bottom of slip ring chamber is provided with arc, and the brush holder support two ends are fixed on the outer wall of slip ring chamber.
Its further technical scheme is: said wind-drive device radially is bell mouth shape.
Its further technical scheme is: the bottom of said brush holder support and slip ring chamber is open.
Useful technique effect of the present invention is:
The present invention shifts out the support inner chamber with slip ring, has simplified the wind path structure of motor body, the rotor dynamic balancing easy operating; Brush holder support and slip ring chamber can VTOL be left slip ring under order, are convenient to change carbon brush and slip ring and safeguard; Brush holder support can be fixed at two ends, is difficult for vibration; The slip ring chamber is provided with independent wind path, and adds wind-drive device, is beneficial to the cooling slip ring; The indoor arc that is provided with of slip ring makes things convenient for carbon dust to collect, and reduces noise.

Embodiment
Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.
As shown in Figure 2, the present invention shifts out support 1 inner chamber with slip ring chamber 2, places support 1 outside, between support 1 and non-shaft stretching end bearing.Slip ring chamber 2 equates with support height of center (the motor base plane is to the distance at motor shaft center), is installed on the sole plate, does not link with support 1.Slip ring 3 is installed within the slip ring chamber 2, and slip ring 3 adopts whole slip ring, is convenient to install, dismantles and safeguards.2 tops, slip ring chamber are provided with independent cooling blower 6, separate with motor main body cooler.2 top boards inner corresponding cooling blower 6 air outlets in slip ring chamber are provided with wind-drive device 5, help the slip ring cooling.Wind-drive device 5 is the bell mouth shape (see figure 3) from radially seeing, the slip ring top is brushed in wind gathering.Slip ring chamber 2 biside plates are equipped with observation window and shutter.
As shown in Figure 3,2 bottoms, slip ring chamber are provided with arc 7, are used to collect carbon dust and discharge.Arc 7 is installed on the sole plate, does not connect with slip ring chamber 2, does not influence the installation and removal of slip ring chamber 2.Brush holder support 4 two ends are fixed on the 2 liang of outer walls in slip ring chamber, and brush holder support 4 is open with 2 bottoms, slip ring chamber, can leave slip ring under order in VTOL, and integral installation and dismounting make things convenient for slip ring to safeguard with carbon brush and change.
Based on said structure, the present invention places slip ring 3 outside the support 1, and separate with support 1 slip ring chamber 2, simplifies the motor body wind path; Can whole install and remove with brush holder support 4 slip ring chamber 2, is convenient to change carbon brush and safeguards slip ring and follow-up rotor dynamic balancing; Slip ring chamber 2 is provided with independent cooling blower 6 and wind-drive device 5, and the slip ring cooling effect is better; Brush holder support 4 employing two ends are fixed, and under high rotating speed, are difficult for producing vibration; 2 bottoms, slip ring chamber are provided with arc 7, make things convenient for carbon dust to collect and cleaning.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from basic design of the present invention, all should think to be included within protection scope of the present invention.
