Abstract
The utility model relates to the technical field of motors and aims to provide a motor housing connection support for a dust collector. The motor housing connection support comprises a motor shaft mounting base, the center of the motor shaft mounting base is provided with a shaft hole, two sides of the motor shaft mounting base extend outwardly to form engaging lug sheets which are connected with a motor housing, the central part of an outer end of one engaging lug sheet is provided with two connection holes, and the central part of an outer end of the other engaging lug sheet is provided with two connection notches. The beneficial effects of the motor housing connection support are that requirements for hole location precision of the connection holes are low, the manufacturing cost is low, and the installation is convenient.
Description
Technical field
The utility model relates to technical field of motors, relates in particular to a kind of suction cleaner using motor shell connection bracket.
Background technology
On dust catcher, all can use motor, stable in order to guarantee motor overall performance, the connection of motor housing is all to connect by connection bracket, in order to guarantee bonding strength, and the various parts of motor internal are positioned, connecting hole and location hole are set in connection bracket simultaneously, the axle of motor also passes from the center of connection bracket simultaneously, so connecting hole in motor housing connecting hole and connection bracket, location hole need to guarantee higher precision in processing, if precision causes connecting normally because of position, hole misalignment when installing not again, and common electric machine connecting support just exists the required precision of position, hole high now, manufacturing cost is high, the problem that installation effectiveness is low.
Chinese patent Granted publication number: CN202997762U, June 12 2013 Granted publication day, a kind of electric machine support is disclosed, be arranged on motor main body output, draw together base and be fixed on the cover plate on described base, offering and hold the through hole that described motor main body output shaft passes on base, through hole offers the first installing hole around, on institute's cover plate, bearing is installed, bearing is coaxial with described through hole.This kind of electric machine support, is comprised of base and cover plate, simple in structure, improves its run stability energy.Its weak point is that this kind of electric machine support is high to position, the hole required precision of connecting hole, installs inconvenient.
Utility model content
The utility model is high to position, hole precision high request in order to overcome motor housing connection bracket of the prior art, manufacturing cost is high, and inconvenient deficiency is installed, and provides a kind of position, hole required precision of connecting hole lower, low cost of manufacture, suction cleaner using motor shell connection bracket easier for installation.
To achieve these goals, the utility model adopts following technical scheme:
A kind of suction cleaner using motor shell connection bracket, comprise motor shaft holder, the center of described motor shaft holder is provided with axis hole, the both sides of described motor shaft holder stretch out and form the attachment lug being connected with motor housing, the middle part, outer end of one of them attachment lug is respectively equipped with two connecting holes, and the middle part, outer end of another attachment lug is provided with two and connects breach.Motor shaft passes from axis hole, in the connecting hole of one side of motor housing, packing bolt into connects, this bolt is not tightened, the connection breach of attachment lug one end is snapped on bolt, then two connecting holes on another attachment lug are connected with bolt and are tighted a bolt with the connecting hole of opposite side on motor housing, last again two bolt tightenings corresponding with connecting breach, so just completed the installation of motor housing connection bracket, even if the center of connecting hole exists a little deviation also can not affect the normal mounting of motor housing connection bracket, the motor housing connection bracket of this kind of structure is low to position, the hole required precision of connecting hole, manufacture processing cost is low, easier for installation.
As preferably, on two attachment lugs, be arranged with reinforcement pit.Because attachment lug integral body is longer, strengthening pit is in order to increase the intensity of attachment lug self, thereby reduces the vibration transmission of rotor, improves the whole service life of motor.
As preferably, on described attachment lug, at the position of strengthening between pit and axis hole, be also provided with location hole.Location hole is connected with the impeller of determining in motor of dust collector, so just determining impeller, motor housing connection bracket, motor housing, all connects into an integral body, and bonding strength is large, and overall performance is stable, reliable.
As preferably, motor shaft holder is provided with bearing chamber, and the openend of described bearing chamber is provided with reinforcement bulge loop.The junction insufficient strength of bearing chamber and motor shaft holder, increases the intensity of motor fixing seat by strengthening bulge loop.
Therefore, position, the hole required precision that the utlity model has connecting hole is lower, low cost of manufacture, beneficial effect easier for installation.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation that partly cuts open of the present utility model.
In figure: motor shaft holder 1 axis hole 2 attachment lug 3 connecting holes 4 connect breach 5 and strengthen pit 6 location hole 7 bearing chambers 8 reinforcement bulge loops 9.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
A kind of suction cleaner using motor shell connection bracket as depicted in figs. 1 and 2, comprise motor shaft holder 1, the center of described motor shaft holder 1 is provided with axis hole 2, on motor shaft holder, be also provided with bearing chamber 8, in bearing chamber 8, be provided with bearing, the openend of bearing chamber 8 is provided with strengthens bulge loop 9, strengthens bulge loop and can effectively increase the bonding strength between bearing chamber and motor shaft holder, thereby improve useful life, motor output shaft passes brearing bore and passes from axis hole, the both sides of described motor shaft holder 1 stretch out and form the attachment lug 3 being connected with motor housing, wherein the middle part, outer end of the attachment lug on the right is provided with two connecting holes 4, the outer end of the attachment lug on the left side is also provided with two and connects breach 5, the base that connects breach is circular-arc, to the distance of axis hole and the center of connecting hole, the distance to axis hole equates in the center of circle of this circular arc, during connection, connecting breach is first stuck on bolt, treat that all connecting hole contrapositions tight a bolt after completing again, thereby make easier for installation, even if the position of connecting hole exists a little deviation also can not affect the normal mounting of motor housing connection bracket, the motor housing connection bracket of this kind of structure is low to position, the hole required precision of connecting hole, manufacture processing cost is low, easier for installation, on two attachment lugs 3, be arranged with and strengthen pit 6, strengthen pit and can increase the intensity of attachment lug, thereby can resist vibration, reduce the transmission of vibration, prevent from resonating between internal structure of motor, thereby improve the useful life of motor, on attachment lug 3, at the position of strengthening between pit 6 and axis hole 2, be also provided with location hole 7, location hole is connected with the impeller of determining in motor of dust collector, so just determining impeller, motor housing connection bracket, motor housing, all connect into an integral body, bonding strength is large, and overall performance is stable, reliable.Therefore, position, the hole required precision that the utlity model has connecting hole is lower, low cost of manufacture, beneficial effect easier for installation.
