Uppfinnare: B W Andersson Foreliggande uppfinning avser en for elektriska impulsgivare avsedd kamskiva med installbar kamlangd och bildad av tva i f6rhallande till varandra vridbara och mot varandra anliggande nock- eller kamforsedda skivor med gemensam axel. Det speeiellt kanneteeknande for uppfinningen är att de kamforsedda skivorna aro lagrade i var sin pa axeln ovridbart fast navdel och vridbara i forhallande till sina navdelar medelst en pa vane navdel anordnad, mot axiell rbrelse last stallskruv, vars gangor ingripa i en pa motsvarande kamforsedda skiva anordnad kuggkrans. Vid en lamplig utforingsform är kuggkransen anordnad pa den yttre mantelytan av ett pa den kamforsedda skivan anordnat ring-format utsprang, sorn ingar i ett ringformigt spar i navdelen, vilken har en tangentiellt till sparet anordnad urtagning far stallskruven.
Inventor: B W Andersson The present invention relates to a cam disc intended for electric pulse transducers with an adjustable cam length and formed by two camshafts or cam-mounted discs with a common shaft which are rotatable relative to one another and abutting one another. The special feature of the invention is that the cam-mounted discs are each mounted in a rotatably fixed hub part on the shaft and rotatable in relation to their hub parts by means of a custom hub part arranged, against axial displacement load stable screw, the passages of which engage in a corresponding cam-mounted disc. gear ring. In a suitable embodiment, the ring gear is arranged on the outer circumferential surface of a ring-shaped projection arranged on the combed disc, which forms an annular groove in the hub part, which has a recess arranged tangentially to the groove for the stable screw.
For fortydligande av hur de i den sammansatta kamskivan inghende detaljerna kunna se ut och hur de samverka hanvisas till bifogade ritning. Fig. 1 visar den sammansatta kamskivan dels sedd frau ena axelanden och dels sedd frail sidan. Fig.2 visar en av de nockeller kamforsedda skivorna med det kuggforsedda ringformiga utspranget. Fig. 3 visar en av navdelama med det ringformiga sparet och med en tangentiellt mot sparet anordnad urtagning. Fig. 4 visar en av snackskruvarna avsedd att anbringas i navdelens tangentiella urtagning. To clarify how the details contained in the composite cam disc can look like and how they work together, reference is made to the attached drawing. Fig. 1 shows the composite cam disc partly seen from one of the shaft ends and partly seen from the side. Fig. 2 shows one of the cam or cam-provided discs with the toothed annular projection. Fig. 3 shows one of the hub parts with the annular recess and with a recess arranged tangentially to the recess. Fig. 4 shows one of the screwdrivers intended to be fitted in the tangential recess of the hub part.
Den reglerbara kamskivan monteras och anvands pa fOljande satt. Skruvarna i navdelarnas tangentiella urtag och de nook- eller kamforsedda skivorna med kuggkransarna f5ras ihop med var sin navdel, sâ att kuggkransarna inga i navdelarnas ringformiga spar. Detta gores sa, att snackskruvarnas kuggar inpassas I kuggarna pa karaskivornas kuggkransar. De erhallna hada enheterna patradas en fyrkantaxel pa sadant satt, att de nock- eller kamforsedda skivorna komma att ligga an mot varandra. Vardera kamskivehalvans navdel är salunda fixerad i forhallande till den ge- mensamma axel de aro upptradda pa, men genom att vardera kamskivehalvans nook- eller kamforsedda skiva Or vridbar relativt resp. navdel, kan man reglera den sammansatta kamskivans flock- eller kamlangd. Detta sker genom att man vrider pa nagon eller hagge av de i navdelarnas tangentiella spar anordnade skruvarna, varvid de flock- eller kamfOrsedda skivorna komma att vridas i forhallande till resp. navdelar. Pa detta salt kan man variera den sammansatta kamskivans nookeller kamlangd och saledes andra den av den sammansatta kamskivan beroende impulstiden. The adjustable cam disc is mounted and used in the following way. The screws in the tangential recesses of the hub parts and the nook- or cam-fitted discs with the toothed rings are brought together with their respective hub parts, so that the toothed rings do not have any annular grooves in the hub parts. This is done so that the teeth of the snack screws fit into the teeth of the toothed rings of the caraway discs. The resulting units are mounted on a square shaft in such a way that the cam- or cam-mounted discs abut each other. The hub part of each cam disc half is thus fixed in relation to the common axis on which they are threaded, but by each cam nozzle or cam-provided disc Or being rotatable relative to resp. hub part, you can adjust the flock or cam length of the composite cam disc. This is done by turning one or more of the screws arranged in the tangential grooves of the hub parts, whereby the flocc- or cam-fitted discs will be rotated in relation to resp. navdelar. On this salt one can vary the cam length of the composite cam disc and thus the second pulse time depending on the composite cam.
Uppfinningen är ej begransad till den nu beskrivna utforingsformen utan kan varieras mom ramen for folj ande patentansprak. The invention is not limited to the embodiment now described but can be varied within the scope of the following patent claims.
