Summary of the invention
The utility model purpose is: the direct current motor of dust collector that a kind of novel shaft connecting mode is provided.
A technical scheme of the present utility model is: a kind of direct current motor of dust collector of novel shaft connecting mode, it comprises: be positioned at an end casing, be contained in casing and have a rotating shaft rotor, be contained in casing and surrounding rotor and the stator that is provided with, be positioned at the other end and have the fan housing of air inlet and be housed in the movable vane wheel of fan housing and decide impeller, wherein said rotating shaft and movable vane are taken turns to fix by a nut and are connected.
One end of rotating shaft described in the utility model is arranged with a lining, and this lining is step-like.
Step-like lining described in the utility model stretches into in the nut.
The spin locking direction of nut described in the utility model is opposite with the direction of rotation of movable vane wheel.
One end of casing described in the utility model is provided with the flange of a ring-type, and its diameter is less than the diameter of deciding impeller.
Flange described in the utility model by at least one screw with decide impeller and interfix.
The utility model advantage is: connect by fixed by nut, coupling mechanism force is arranged during electric motor starting, be difficult for becoming flexible, and lining adopts ledge structure, increase and movable vane wheel fit diameter, Stability Analysis of Structures, life-saving.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the cutaway view of prior art shaft connected mode;
Fig. 2 is an exploded perspective view of the present utility model;
Fig. 3 is a cross-sectional schematic of the present utility model;
Wherein: 10, casing; 12, flange; 20, fan housing; 22, nut; 2,30, movable vane wheel; 3,32, trim ring; 31,320, trim ring hole; 34, lining; 40, decide impeller; 42, air-out passage; 44, screw; 50, rotor; 60, stator; 100, rotating shaft; 102, air outlet.
Embodiment
Embodiment: shown in figure 2-3, the utility model provides a kind of specific embodiment of direct current motor of dust collector of novel shaft connecting mode, and it comprises the casing 10 that is positioned at an end and has flange 12, be contained in the casing 10 and have the rotor 50 of a rotating shaft 100, the stator 60 that is contained in casing 10 interior also surrounding rotors 50 and is provided with, be positioned at the other end and have the fan housing 20 of air inlet (not label), be housed in the movable vane wheel 30 in the fan housing 20, what be positioned at that movable vane takes turns 30 belows and have several air channels 42 decides impeller 40, and be positioned at 30 times sheets of movable vane wheel on, lower clamping ring 32.Its shaft 100 and movable vane wheel 30 fixes by a nut 22 and is connected, and nut 22 has T shape hole, and it is opposite that the spin locking direction of nut 22 and movable vane are taken turns 30 direction of rotation, and upper and lower trim ring 32 includes the trim ring hole 320 that is positioned at the center.
Casing 10 is the cylinder of an end opening and interior hollow, the employing metal material is made, and flange 12 is positioned at the openend of casing 10, profile in the form of a ring, its diameter is less than the diameter of deciding impeller 40, and greater than the diameter of casing 10, the part that makes the air channel 42 of deciding impeller 40 be positioned at flange 12 outsides is exposed outside, guarantee to discharge by the exposed excessively air channel 42 of the movable vane wheel 30 part air communication of coming out, and the part air-flow enters into casing 10 because of the air channel that is positioned at flange 12 inside parts, flow through gap between rotor 50 and the stator 60, the air outlet 102 from casing 10 flows out at last.This flange 12 with decide impeller 40 by plane contact, and by several screws 44 at least and decide impeller 40 and interfix.Realize good fixing thus, and be convenient to miniaturization, densification, low cost, and it is more smooth and easy to make that internal gas flow flows.
One end of rotating shaft 100 is arranged with the lining 34 that is step-like, and this lining 34 is at movable vane wheel 30 and decide between the impeller 40, through the hole of upper and lower trim ring hole 320 and movable vane wheel 30 and stretch in the T shape hole of nut 22 into, to strengthen fixing of rotating shaft 100 and movable vane wheel 30.
The utility model connects by fixed by nut, and coupling mechanism force is arranged during electric motor starting, be difficult for becoming flexible, and lining adopts ledge structure, increase and movable vane wheel fit diameter, Stability Analysis of Structures, life-saving.
