Definitions

  • the invention based on the shearer loader of the type mentioned at the outset, proposes that the housing section of the gearbox housing adjoining the support arm has a separate, radially protruding fastening flange that can be fixed by means of a separate screw connection to a matching counter flange at the free end of the support arm .
  • the separate screw connection for fixing the gear housing on the support arm has screw bolts and preload nuts which can be mechanically fixed in the preloaded position.
  • Such hydraulically pretensionable screw connections have the advantage that they can apply a precisely defined pretensioning force easily and with greater security, which is particularly important for the connection between the support arm and the gear housing, as the extremely high torques of the cutting roller must be supported via this flange connection .

Claims (3)

  1. Haveuse-chargeuse à tambour pour l'extraction minière en longues tailles, avec un corps de machine (1) pouvant être déplacé le long d'un convoyeur de taille (2) dans le sens longitudinal de front de taille et au moins un tambour de coupe (4), qui est supporté par un bras de support (3) fixé de manière à pouvoir pivoter au niveau du corps de machine (1), est monté au niveau de l'extrémité libre du bras de support (3) de manière à pouvoir tourner autour d'un axe s'étendant de manière parallèle par rapport au toit du filon et de manière perpendiculaire par rapport au front de taille et peut être entraîné par un moteur d'entraînement associé au bras de support (3) par l'intermédiaire d'une chaîne de transmission disposée dans l'intérieur du bras de support (3) et d'une transmission planétaire se trouvant au niveau de l'extrémité libre du bras de support (3), dont le boîtier de transmission (5) relié sans possibilité de rotation à la section d'extrémité du bras de support (3) est constitué de sections de boîtier (5a, 5b, 5c) annulaires alignées les unes aux autres de manière axiale, qui sont maintenues ensemble par des boulons filetés (6) se trouvant au niveau de leur périphérie,
    caractérisée en ce
    que la section de boîtier (5c), jouxtant le bras de support (3), du boîtier de transmission (5) présente une bride de fixation (7) distincte, faisant saillie de manière radiale, qui peut être immobilisée au moyen d'une liaison par vissage (8, 9) distincte au niveau d'une contre-bride (10) adaptée à celle-ci au niveau de l'extrémité libre du bras de support (3).
  2. Haveuse-chargeuse à tambour selon la revendication 1, caractérisée en ce qu'une liaison solidaire en rotation entre la dernière roue dentée de la chaîne de transmission se trouvant dans le bras de support (3) et l'arbre d'entraînement de la transmission planétaire a lieu par un élément composite cannelé (12), lequel peut être enfilé, lorsque la transmission planétaire est montée, depuis le côté décalé, dans des ouvertures de logement adaptées dans la dernière roue dentée de la chaîne de transmission ou de l'arbre d'entraînement de la transmission planétaire.
  3. Haveuse-chargeuse à tambour selon la revendication 1, caractérisée en ce que la liaison par vissage (8, 9) distincte servant à immobiliser le boîtier de transmission (5) au niveau du bras de support (3) présente des boulons filetés (8) et des écrous de précontrainte (9), qui peuvent être bloqués de manière mécanique dans la position précontrainte.
