Description
Oppfinnelsen vedrører universalledd. Mer særskilt vedrører oppfinnelsen et universalledd som innbefatter et plastlager i innrettede åpninger i armene til åkene i et universalledd. The invention relates to universal joints. More specifically, the invention relates to a universal joint which includes a plastic bearing in aligned openings in the arms of the yokes in a universal joint.
I noen kjente universalledd, eksempelvis universalledd som benyttes i noen automobil-styremekanismer, er det anordnet plastringskiver mellom navet i universalleddet og hver åk- In some known universal joints, for example universal joints used in some automobile steering mechanisms, plastic washers are arranged between the hub in the universal joint and each yoke
arm i leddet. Disse skivene reduserer gnidningsfriksjonen mellom nav og armer og virker også som smussbeskyttelser eller tetninger. Dreiemomentet overføres fra åkarmene til navet gjennom nållagre som er montert på tapper som rager ut fra navet. arm in joint. These washers reduce the rubbing friction between hub and arms and also act as dirt guards or seals. The torque is transmitted from the yokes to the hub through needle bearings mounted on pins that protrude from the hub.
Oppfinnelsen vedrører et universalledd som innbefatter et åk med gaffelarmer. Armene har boringer som flukter med hverandre. Et plastlager som er innsatt i hver boring har en langsgående boring som strekker seg fra innsiden av lageret og i det minste delvist gjennom lageret for opptak av tapper. The invention relates to a universal joint which includes a yoke with fork arms. The arms have bores that align with each other. A plastic bearing inserted into each bore has a longitudinal bore extending from the inside of the bearing and at least partially through the bearing for receiving pins.
Oppfinnelsen skal forklares nærmere under henvisning til tegningsfigurene, hvor: Fig. 1 viser et eksplosjonsriss av et universalledd ifølge oppfinnelsen, og The invention shall be explained in more detail with reference to the drawings, where: Fig. 1 shows an exploded view of a universal joint according to the invention, and
fig. 2 viser et snitt gjennom universalleddet i fig. 1 i sammensatt tilstand. fig. 2 shows a section through the universal joint in fig. 1 in assembled state.
Universalleddet innbefatter et første åk med gaffelarmer 12The universal joint includes a first yoke with fork arms 12
og 14. Armene 12 og 14 har en respektiv boring 15 og 18.and 14. The arms 12 and 14 have a respective bore 15 and 18.
Disse boringene flukter med hverandre. Et andre åk er<*>~utformet med gaffelarmer 22 og 24 og har i flukt med hver- These bores are flush with each other. A second yoke is<*>~formed with fork arms 22 and 24 and has flush with each-

En boring 32 går gjennom navet 3 0 perpendikulært på navflaten 34. En lignende boring 36 går gjennom navet 30, perpendikulært på navflaten 38. Boringens 32 akse er perpendikulær på boringens 36 akse. De to aksene krysser hverandre i nav- A bore 32 passes through the hub 30 perpendicular to the hub face 34. A similar bore 36 passes through the hub 30, perpendicular to the hub face 38. The axis of the bore 32 is perpendicular to the axis of the bore 36. The two axes cross each other at the nav-
et 30.a 30.
Universalleddet innbefatter også plastlagre 40, 42, 44 og 46. Lageret 40 har en skulder 48 i en overgang mellom et parti 50 med større diameter og et parti 52 med mindre diameter. Lagerne 42, 4 4 og 4 6 er utformet på samme måte. The universal joint also includes plastic bearings 40, 42, 44 and 46. The bearing 40 has a shoulder 48 in a transition between a part 50 with a larger diameter and a part 52 with a smaller diameter. The bearings 42, 4 4 and 4 6 are designed in the same way.
Universalleddet innbefatter også en tapp 54 med et sentralt plassert omløpende ringspor 56. Dessuten innbefatter universalleddet to kortere tapper 58 og 60. Hver av disse har et V-formet spor 62 og 64. Hvert av de nevnte lagre, se eksempelvis lageret 40, har en langsgående boring 66 som kan strekke seg delvist gjennom lageret i fra innerflaten 67 (se fig. 2), men som fortrinnsvis går helt gjennom lageret. The universal joint also includes a pin 54 with a centrally located circumferential ring groove 56. The universal joint also includes two shorter pins 58 and 60. Each of these has a V-shaped groove 62 and 64. Each of the aforementioned bearings, see for example the bearing 40, has a longitudinal bore 66 which can extend partially through the bearing i from the inner surface 67 (see fig. 2), but which preferably goes completely through the bearing.
Når universalleddet skal samles føres lagerne 40 og 4 2 inn i hullene 16 og 18. Lagerne 44 og 46 plasseres i hullene 26 When the universal joint is to be assembled, bearings 40 and 4 2 are inserted into holes 16 and 18. Bearings 44 and 46 are placed in holes 26
og 28. Navet 30 plasseres så mellom åkene, idet boringen 36 flukter med boringene 16, 18 og boringen 32 flukter med boringene 26, 28. Tappen 54 kan så stikkes inn gjennom boringen 66 i lageret 40. Dette skjer fra utsiden av universalleddet. Tappen føres gjennom boringen 36 og gjennom boringen 68 i lageret 42. Deretter føres tappene 58 på plass i fra utsiden av leddet, idet de føres gjennom boringene 70 og 72 i lagerne 44, 46, og inn i boringen 32. De V-formede sporene 62 og 64 på tappene 58 og 60 passer rundt sylinder-flaten i ringsporet 56 på tappen 54. and 28. The hub 30 is then placed between the yokes, with the bore 36 aligned with the bores 16, 18 and the bore 32 aligned with the bores 26, 28. The pin 54 can then be inserted through the bore 66 in the bearing 40. This happens from the outside of the universal joint. The pin is passed through the bore 36 and through the bore 68 in the bearing 42. Then the pins 58 are passed into place from the outside of the joint, being passed through the bores 70 and 72 in the bearings 44, 46, and into the bore 32. The V-shaped grooves 62 and 64 on the pins 58 and 60 fit around the cylinder surface in the ring groove 56 on the pin 54.
Av fig. 2 går det frem at når universalleddet er samletFrom fig. 2 states that when the universal joint is assembled
vil hvert lager, eksempelvis lageret 40, være plassert i boringen 16 i en åkarm 14 slik at lagerskulderen 48 ligger an mot innerflaten 49 på armen 14. Partiet 52 med den each bearing, for example the bearing 40, will be located in the bore 16 in a yoke arm 14 so that the bearing shoulder 48 rests against the inner surface 49 of the arm 14. The part 52 with the
mindre diameter går gjennom boringen 16. På lignende måte ligger skulderne på de andre lagerne 42, 44, 46 an mot innerflaten på tilhørende arm, idet partiet med mindre diameter går gjennom boringen i armen. smaller diameter goes through the bore 16. In a similar way, the shoulders of the other bearings 42, 44, 46 rest against the inner surface of the associated arm, the part with the smaller diameter going through the bore in the arm.
Oppfinnelsen fjerner behovet for dyre nålelagre. Den elimin-erer også behovet for individuelle lagre som er adskilt fra trykkskivene. Fordi lagerne er forsynt med åpne boringer som muliggjør en innføring av tappene fra utsiden av armene lettes sammensettingen av universalleddet sammenlignet med sammensettingen av de vanlige universalledd hvor det innbefatter nålelagre med lukkede ender. The invention removes the need for expensive needle bearings. It also eliminates the need for individual bearings that are separate from the thrust washers. Because the bearings are provided with open bores that enable the pins to be inserted from the outside of the arms, the assembly of the universal joint is facilitated compared to the assembly of the usual universal joints where it includes needle bearings with closed ends.
Lagerne kan tilformes av ulike plastmaterialer med selv-smørende egenskaper. Lagerne kan også fremstilles med smøremiddellommer dersom det er nødvendig med ekstra smøre-middelkapasitet. The bearings can be made of various plastic materials with self-lubricating properties. The bearings can also be manufactured with lubricant pockets if extra lubricant capacity is required.
