Ekiwandiiko kya Globoidal Cam Indexer

Globoidal Cam Indexer kye ki?

Globoidal cam indexer (era eyitibwa barrel cam oba Roller Gear Cam indexer) kye kyuma ekitambula obulungi ekikyusa okuyingiza okutambula okutambula obutasalako mu kutambula okutambula okutambula obutasalako, okutambula obulungi okutambula oba okufuluma okw’ennyiriri nga tukozesa cam eriko enkula y’essaawa- (globoidal) ekwata ku rollers eziteekeddwa ku turret oba output shaft. Ewa entambula ya indexing etandikirawo ennyo, ennungi-stop indexing nga erimu okukankana n'okukankana okutono bw'ogeraageranya n'enkola endala ez'okulaga index.

Enkula

Ebitundu ebikulu mulimu cam eriko globoidal (barrel-shaped) nga erina helical groove ekoleddwa mu kyuma mu ngulu yaayo, output turret etekeddwamu cam-follower rollers eziwera ezikwata groove, n’ennyumba enkalu ewanirira byombi cam shaft ne turret shaft ku precision bearings. Nga cam yeekulukuunya obutasalako, groove’s variing lead angle evuga rollers-era bwekityo turret-nga eyita mu alternating dwell ne index (motion) phases munda mu cam rotation emu.

Ebintu Ebirina Okulowoozebwako mu Kulonda

Ensonga enkulu mulimu omuwendo gwa siteegi za index, enkoona y’omuwendo, omugerageranyo gw’obudde bw’okubeera, torque y’okufulumya n’obusobozi bw’obutakola, ekika kya motion curve (modified sine, modified trapezoidal) ekikosa velocity/acceleration smoothness, positioning accuracy/repeatability, ne permissible input speed. Load inertia ne cycle rate eyeetaagisa birina okukwatagana ne cam sizing okwewala okukankana okuyitiridde oba okwambala nga tekunnabaawo.

Okusaba

Globoidal cam indexers zikozesebwa mu byuma ebipakinga, layini z’okuteeka mu bucupa n’okuwandiika, okukuŋŋaanya mu ngeri ey’obwengula, ebyuma ebikuba ebitabo, n’enkola z’okutambuza enzitoya nga entambula entuufu, eddiŋŋanwa ey’ekiseera ekigere yeetaagibwa ku miwendo gya cycle egy’amaanyi.

Ebintu Ebirina Okulowoozebwako mu Kussaawo

Okukwatagana obulungi wakati wa cam shaft ne turret output shaft kyetaagisa okukuuma obutuufu bw’okukwatagana kwa roller. Omusingi gw'okussaako gulina okuba omugumu era nga tegukankana-okukuuma obutuufu bw'okuwandiika. Okusiiga (mu ngeri entuufu oil bath) kulina okukakasibwa nga tonnatandika, era backlash/preload wakati wa rollers ne cam groove kulina okukeberebwa n’okutereezebwa okusinziira ku manufacturer specification mu kiseera ky’okutandika okukola.

Wano Mu lupapula luno, twanjula DF Flange Model Cam Indexers okuva mu TallMan Robotics, ojja kulaba data sheet, ebifaananyi by'okufulumya,vedios nga bwe biti:
