Abstract
Description
Foreliggende oppfinnelse angår en innretning for koaksial, dreiefast og aksialt sperrbar forbindelse mellom et drev og en motor-drivaksel, med langsgående spor og ribber i innbyrdes inngrep for dannelse av den dreiefaste forbindelse og en radialt rettet tapp for dannelse av den aksiale sperring, idet drevet oppviser en akseltapp med to utvendige sylinderpartier og et fortannet parti mellom disse partier, mens drivakselen oppviser et innvendig fortannet parti og aksialt utenfor hver ende av dette innvendige sylinderpartier som er tilpasset hvert sitt av de utvendige sylinderpartier på akseltappen, og slik at det fortannede parti på henholdsvis akseltappen og drivakselen kan bringes i innbyrdes inngrep når drevet og drivakselen føres koaksialt sammen, styrt av sylinderpartiene. The present invention relates to a device for a coaxial, rotatable and axially lockable connection between a drive and a motor drive shaft, with longitudinal grooves and ribs in mutual engagement to form the rotatable connection and a radially directed pin to form the axial lock, the drive shows an axle pin with two external cylinder parts and a toothed part between these parts, while the drive shaft shows an internal toothed part and axially outside each end of this internal cylinder parts which are adapted to each of the external cylinder parts on the axle pin, and so that the toothed part on respectively, the axle pin and the drive shaft can be brought into mutual engagement when the drive and the drive shaft are guided coaxially together, controlled by the cylinder parts.
En slik innretning fremgår av US.patent 2578838. Med den kjente innretning kan det oppnås en tilfredsstillende sammenkobling med hensyn til å hindre innbyrdes dreining og aksialbevegelse, men for industrielle anvendelser kan de innbyrdes radialbevegelser bli større enn hva som er akseptabelt. Selv små innbyrdes radialbevegelser kan, særlige ved høye omdreiningstall, føre til merkbar og uakseptabel ubalanse. I en utførelse vist i skriftets fig. 1 forutsettes det anlegg mellom delene i en tverrgående flate, samtidig med at tappen befinner seg i nøyaktig tilpassede hull i hver av delene. Det kreves derfor stor nøyaktighet både med hensyn til hulldiameter i forhold til tappdiameter og med hensyn til hullenes beliggenhet i forhold til flaten. Selv en meget liten feil med hensyn til hullenes beliggenhet vil medføre enten at tappen ikke lar seg sette på plass eller at det ikke er kontakt i flaten når tappen er satt på plass. I det sistnevnte tilfellet må aksialbelastninger opptas av tappen alene. Det må dessuten forutsettes at det er trang pasning mellom tappen og hullene, slik at forbindelsen ikke lar seg løse på en enkel måte. Such a device appears in US patent 2578838. With the known device, a satisfactory connection can be achieved with regard to preventing mutual rotation and axial movement, but for industrial applications the mutual radial movements can be greater than is acceptable. Even small mutual radial movements can, especially at high revolutions, lead to a noticeable and unacceptable imbalance. In an embodiment shown in the document's fig. 1, it is assumed that the parts fit together in a transverse surface, at the same time that the pin is located in precisely adapted holes in each of the parts. Great accuracy is therefore required both with regard to hole diameter in relation to pin diameter and with regard to the location of the holes in relation to the surface. Even a very small error with regard to the location of the holes will result either in the pin not being able to be put in place or in the fact that there is no contact in the surface when the pin is put in place. In the latter case, axial loads must be absorbed by the pin alone. It must also be assumed that there is a tight fit between the pin and the holes, so that the connection cannot be loosened easily.
Disse ulemper unngås med innretningen i henhold til den foreliggende oppfinnelse, som kjennetegnes ved at drivakselen oppviser en tverrgående, gjenget tapp med en konisk eller stumpkonisk indre ende, mens det ene sylinderpartiet på akseltappen har et ringspor med radialt divergerende flater, og med et tverrsnitt som er tilpasset den indre enden til tappen, for dannelse av den aksiale sperring, og at når akseltappen og drivakselen er ført helt sammen er aksen til tappen forsatt mot den frie enden av akseltappen i forhold til ringsporet, slik at tilskruing av tappen bevirker at endeflater på drevet og drivakselen trykkes mot hverandre. These disadvantages are avoided with the device according to the present invention, which is characterized by the fact that the drive shaft has a transverse, threaded pin with a conical or blunt-conical inner end, while one cylinder part of the shaft pin has an annular groove with radially diverging surfaces, and with a cross-section which is adapted to the inner end of the pin, to form the axial lock, and that when the axle pin and the drive shaft are brought completely together, the axis of the pin is offset towards the free end of the axle pin in relation to the ring groove, so that screwing the pin causes the end surfaces of the drive and the drive shaft are pressed against each other.
Tappen vil således, uten at det stilles høye krav til toleranser, alltid kunne skrus inn i ringsporet slik at enden av tappen trykker mot den siden i ringsporet som er nærmest den frie enden av akseltappen, og endeflatene på drevet og drivakselen vil alltid kunne trykkes sammen. Forbindelsen lar seg enkelt løsgjøre, ved at tappen skrus noe ut. The pin will thus, without high demands on tolerances, always be screwed into the ring groove so that the end of the pin presses against the side of the ring groove that is closest to the free end of the shaft pin, and the end faces of the drive and the drive shaft will always be able to be pressed together . The connection can be easily loosened by unscrewing the pin slightly.
Andre fordeler og trekk ved oppfinnelsen vil fremgå av den følgende beskrivelse, i hvilken det skal forklares et utførelseseksempel av oppfinnelsen, under henvisning til den vedføyde tegning. Other advantages and features of the invention will be apparent from the following description, in which an embodiment of the invention will be explained, with reference to the attached drawing.
Figur 1 viser et lengdesnitt gjennom en innretning i Figure 1 shows a longitudinal section through a device i
henhold til oppfinnelsen. according to the invention.
Figur 2 viser et snitt gjennom fortanningen, etter linjen Figure 2 shows a section through the toothing, following the line
II-II i figur 1. II-II in figure 1.
Innretningen 1 i henhold til oppfinnelsen tjener til dreiefast forbindelse mellom en motor-drivaksel 2 og et drev 3 som kan dreie sammen. Akselen 2 har fra en ende 4 en aksial boring 5, som først utgjøres av et sylinderparti 6, som går over i et fortannet parti 7, med et sportverrsnitt som høyst er så stort som diameteren til sylinderpartiet 6. I det viste eksempel går det fortannede partiet 7 over i et annet sylinderparti 8, med en diameter som høyst er så stor som diameteren til tanntoppene i det fortannede partiet 7. I boringen 5 er innført en akseltapp 9 på drevet 3, med en utformning som er komplementær med den beskrevne utformning av boringen 5 og således omfatter et ytre sylinderparti 10 med en diameter som tilsvarer diameteren til det indre sylinderpartiet 6. Dette parti går over i et ytre fortannet parti 11, som er utformet komplementært med det indre fortannede parti 7. Deretter følger et ytre sylinderparti 12 med en ytterdiameter som tilsvarer diameteren til det indre sylinderpartiet 8. På sin frie ende er akseltappen 9 på drevet 3 utstyrt med et ringspor 13. I samme aksiale stilling som ringsporet 13 på akseltappen 9 har akselen 2 i det minste en tverrliggende, gjenget boring 15, i hvilken en gjenget tapp 14 med en indre ende 16 som er tilpasset ringsporet 13 er innskrudd, og enden 16 rager inn i sporet 13 på akseltappen 9. Derved sperres drevet 3 aksialt, idet den med den enden 17 som vender mot akselen 2 ligger mot endeflaten 4 på akselen 2. Den innbyrdes sentrering mellom akselen 2 og drevet 3 skjer ved hjelp av sylinderpartiene 6, 10 og 8, 12, mens dreiemomentoverføringen skjer ved hjelp av de fortannede partiene 7, 11. Dreiemomentoverføringen og sentreringen skjer således adskilt i innretningen i henhold til oppfinnelsen. På akselen 2 kan det være montert en sprederskive 18, for å forhindre at f.eks. en olj estråle som kommer ut mellom fortanningene kommer frem til en akseltet-ningsring 19. Motorakselen 2 er utstyrt med et lager 20. The device 1 according to the invention serves as a rotatable connection between a motor drive shaft 2 and a drive 3 which can turn together. The shaft 2 has, from one end 4, an axial bore 5, which is first made up of a cylinder part 6, which transitions into a toothed part 7, with a cross section which is at most as large as the diameter of the cylinder part 6. In the example shown, the toothed part the part 7 over into another cylinder part 8, with a diameter that is at most as large as the diameter of the tooth tops in the toothed part 7. In the bore 5, a shaft pin 9 is introduced on the drive 3, with a design that is complementary to the described design of the bore 5 and thus comprises an outer cylinder part 10 with a diameter corresponding to the diameter of the inner cylinder part 6. This part transitions into an outer toothed part 11, which is designed complementary to the inner toothed part 7. Then follows an outer cylinder part 12 with an outer diameter that corresponds to the diameter of the inner cylinder part 8. At its free end, the axle pin 9 on the drive 3 is equipped with an annular groove 13. In the same axial position as the annular groove 13 on the axle pin 9, the shaft 2 has at least one transverse, threaded bore 15, in which a threaded pin 14 with an inner end 16 which is adapted to the ring groove 13 is screwed in, and the end 16 projects into the groove 13 on the axle pin 9. Thereby the drive 3 is blocked axially, with the end 17 facing the shaft 2 lying against the end surface 4 of the shaft 2. The mutual centering between the shaft 2 and the drive 3 takes place by means of the cylinder parts 6, 10 and 8, 12, while the torque transmission takes place by means of the toothed parts 7, 11. The torque transmission and centering thus take place separately in the device according to the invention. A spreader disc 18 can be mounted on the shaft 2, to prevent e.g. an oil jet that comes out between the teeth reaches a shaft sealing ring 19. The motor shaft 2 is equipped with a bearing 20.
