Description
Oppfinnelsen vedrorer en lagring for rotorakselen for elektromotorer, hvor rotorakselen bærer et viftehjul for opprettelse av undertrykk eller overtrykk. The invention relates to a bearing for the rotor shaft for electric motors, where the rotor shaft carries a fan wheel for creating underpressure or overpressure.
I denne forbindelse kjennes forskjellige lagringer. Det fins f.eks. lagringer med lagre som krever en aksial reguleringskraft for at upåklagelig funksjon skal sikres. Det gjelder lagre som f.eks. vinkelkontaktlagre, kuleskallagre eller ku-lelagre som opptar både aksiale og radiale krefter. Ved de kjente konstruksjonene påvirkes disse lagre med en aksial reguleringskraft via en separat anordning. In this connection, different storages are known. There are e.g. bearings with bearings that require an axial adjustment force to ensure impeccable function. This applies to warehouses such as angular contact bearings, ball shell bearings or ball bearings which absorb both axial and radial forces. In the known constructions, these bearings are affected by an axial regulating force via a separate device.
Det er i denne forbindelse uheldig at det for en upåklagelig funksjon kreves ekstra komponenter, som fjærer, kuler eller andre organer. Foreliggende oppfinnelse går ut på å gjore lagringen så enkel som mulig. In this connection, it is unfortunate that extra components, such as springs, balls or other organs, are required for an impeccable function. The present invention aims to make storage as simple as possible.
Ifolge oppfinnelsen loses denne oppgave ved at det under utnyttelse av den aksialkraft som genereres av viftehjulet under drift, på viftehjulsiden er anordnet et lager, som ut fra sin konstruksjon krever en aksial reguleringskraft, f. eks. et kulelager som opptar aksial og radial kraft, og at det ikke foreligger noen ekstra anordning for tilveiebrin-gelse av en aksial reguleringskraft. According to the invention, this task is solved by utilizing the axial force generated by the fan wheel during operation, a bearing is arranged on the fan wheel side, which, based on its construction, requires an axial regulating force, e.g. a ball bearing that absorbs axial and radial force, and that there is no additional device for providing an axial regulating force.
Det kan være fordelaktig at det er anordnet et glidelager på motstående side. Dessuten er det viktig at den aksialkraft som genereres av viftehjulet ved drift ovenfra, er storre enn kraften av rotorens 6 vekt. Denne konstruksjon har den avgjorende fordel at en separat anordning for opprettelse av den aksiale reguleringskraft kan falle bort. It can be advantageous if a sliding bearing is arranged on the opposite side. Furthermore, it is important that the axial force generated by the fan wheel when operating from above is greater than the force of the rotor's 6 weight. This design has the decisive advantage that a separate device for creating the axial regulating force can be dispensed with.
Et utforelseseksempel av oppfinnelsen er vist i tegningen og nærmere omtalt nedenfor. Figuren er et lengdesnitt gjennom et stovsugerhus i forenklet gjengivelse. An embodiment of the invention is shown in the drawing and discussed in more detail below. The figure is a longitudinal section through a vacuum cleaner housing in a simplified representation.
Figuren viser et lengdesnitt gjennom et stovsugerhus 7, som The figure shows a longitudinal section through a vacuum cleaner housing 7, which
I IN
er gjengitt i forenklet form og kuttet bak motorrommet 8. Stovsugerhuset 7 omfatter motorrommet 8 sugerommet 9. I motorrommet 8 er det anordnet en elektromotor 10, som er fes-tet på skilleveggen 11 mellom motorrommet 8 og sugerommet 9. Elektromotoren griper med sin aksel 12 inn i sugerommet og bærer et viftehjul 13 der. is reproduced in simplified form and cut behind the motor compartment 8. The vacuum cleaner housing 7 includes the motor compartment 8 and the suction compartment 9. In the motor compartment 8 there is an electric motor 10, which is attached to the partition wall 11 between the motor compartment 8 and the suction compartment 9. The electric motor grips with its shaft 12 into the suction chamber and carries a fan wheel 13 there.
Den totale lagring av rotoren 6 og akselen 12 er konstruert som folger: På elektromotorens 10 vifteside er det anordnet et lager 2, som ut fra sin konstruksjon normalt krever en aksial regu-leringskraf t, i dette tilfelle et kulelager 3 av den type som opptar både aksialt og radialt trykk. Dette omfatter en ytre ring 14, en indre ring 13 og kuler 16, som er sammen-satt slik at kulelagret kunne trekkes fra hverandre i retning av motstående side 4 av elektromotoren, 10. På motstående side 4 er det anordnet et glidelager.5. Dette omfatter en filtring 17, en klembrille 18 og et deksel 19. I tillegg er det anordnet en opplopsskive 20. Under drift genereres et undertrykk i sugerommet 9. Sugerommets 9 utlopsåpning (ikke vist) befinner seg bak viftehjulet 13 i tegningsretning. The total storage of the rotor 6 and the shaft 12 is designed as follows: On the fan side of the electric motor 10, a bearing 2 is arranged, which, based on its construction, normally requires an axial regulating force, in this case a ball bearing 3 of the type that occupies both axial and radial pressure. This comprises an outer ring 14, an inner ring 13 and balls 16, which are assembled so that the ball bearing could be pulled apart in the direction of the opposite side 4 of the electric motor, 10. On the opposite side 4, a sliding bearing is arranged. 5. This includes a filter 17, a clamping glass 18 and a cover 19. In addition, there is a baffle plate 20. During operation, a negative pressure is generated in the suction chamber 9. The outlet opening of the suction chamber 9 (not shown) is located behind the fan wheel 13 in the direction of the drawing.
Undertrykket i sugerommet 9 bevirker nå en aksialkraft i den retning som er antydet med pilen. Som folge av dette vil indre ring 15 og ytre ring 14 via kulene 16 presses mot hverandre i kulelageret 3, slik at en separat anordning for opprettelse av en aksial justeringskraft kan falle bort. The negative pressure in the suction chamber 9 now causes an axial force in the direction indicated by the arrow. As a result of this, the inner ring 15 and outer ring 14 via the balls 16 will be pressed against each other in the ball bearing 3, so that a separate device for creating an axial adjustment force can be omitted.
I tilefelle tyngdekraftretningen også er identisk med pilens retning, vil rotorens 6 vekt holde kulelageret 3 sammen ved stillstand. Ved drift ovenfra, dvs. når tyngdekraftens retning virker mot pilens retning, sorger opplopsskiven 20 for at rotoren ved stillstand er i anlegg mot glidelageret.. 5. Ved denne driftstype er det dog viktig at aksialkraften som opprettes som folge av undertrykket er storre enn rotorens 6 vekt. If the direction of gravity is also identical to the direction of the arrow, the weight of the rotor 6 will hold the ball bearing 3 together at standstill. When operating from above, i.e. when the direction of gravity acts against the direction of the arrow, the baffle plate 20 ensures that the rotor is in contact with the sliding bearing at standstill. 6 weight.
