Diff\u00e9rence entre les poulies folles et les poulies de tension<\/h2>\n

Il existe deux types fondamentaux de poulies\u00a0: la les poulies folles et les poulies de tension<\/a>, mais leur r\u00f4le et leur conception sont similaires.<\/p>\n

Poulie de tension<\/h3>\n

Une poulie de tension utilise un bras \u00e0 ressort ou un actionneur hydraulique pour appliquer la pression appropri\u00e9e et aider \u00e0 maintenir la courroie tendue et align\u00e9e. Dans un syst\u00e8me de courroie d\u2019entra\u00eenement, la poulie de tension est dot\u00e9e d\u2019un ressort pour maintenir la tension et l\u2019alignement corrects de la courroie auxiliaire.<\/p>\n

Poulie folle<\/h3>\n

La poulie folle est boulonn\u00e9e sur le moteur et sert de guide pour enrouler la courroie de distribution dans le bon sens.[\/vc_column_text][\/vc_column_inner][vc_column_inner column_padding=\u00a0\u00bbno-extra-padding\u00a0\u00bb column_padding_tablet=\u00a0\u00bbinherit\u00a0\u00bb column_padding_phone=\u00a0\u00bbinherit\u00a0\u00bb column_padding_position=\u00a0\u00bball\u00a0\u00bb column_element_direction_desktop=\u00a0\u00bbdefault\u00a0\u00bb column_element_spacing=\u00a0\u00bbdefault\u00a0\u00bb desktop_text_alignment=\u00a0\u00bbdefault\u00a0\u00bb tablet_text_alignment=\u00a0\u00bbdefault\u00a0\u00bb phone_text_alignment=\u00a0\u00bbdefault\u00a0\u00bb background_color_opacity=\u00a0\u00bb1″ background_hover_color_opacity=\u00a0\u00bb1″ background_image=\u00a0\u00bb39195″ background_image_position=\u00a0\u00bbcenter center\u00a0\u00bb background_image_stacking=\u00a0\u00bbdefault\u00a0\u00bb enable_bg_scale=\u00a0\u00bbtrue\u00a0\u00bb background_image_loading=\u00a0\u00bbdefault\u00a0\u00bb column_backdrop_filter=\u00a0\u00bbnone\u00a0\u00bb column_shadow=\u00a0\u00bbnone\u00a0\u00bb column_border_radius=\u00a0\u00bbnone\u00a0\u00bb column_link_target=\u00a0\u00bb_self\u00a0\u00bb overflow=\u00a0\u00bbvisible\u00a0\u00bb gradient_direction=\u00a0\u00bbleft_to_right\u00a0\u00bb overlay_strength=\u00a0\u00bb0.3″ width=\u00a0\u00bb1\/3″ tablet_width_inherit=\u00a0\u00bbdefault\u00a0\u00bb animation_type=\u00a0\u00bbdefault\u00a0\u00bb bg_image_animation=\u00a0\u00bbnone\u00a0\u00bb border_type=\u00a0\u00bbsimple\u00a0\u00bb column_border_width=\u00a0\u00bbnone\u00a0\u00bb column_border_style=\u00a0\u00bbsolid\u00a0\u00bb column_padding_type=\u00a0\u00bbdefault\u00a0\u00bb gradient_type=\u00a0\u00bbdefault\u00a0\u00bb][divider line_type=\u00a0\u00bbNo Line\u00a0\u00bb custom_height=\u00a0\u00bb22vh\u00a0\u00bb][\/vc_column_inner][\/vc_row_inner][divider line_type=\u00a0\u00bbNo Line\u00a0\u00bb custom_height=\u00a0\u00bb10″][vc_column_text]\n

Huit sympt\u00f4mes d\u2019une poulie d\u00e9fectueuse<\/h2>\n

Nous sugg\u00e9rons aux m\u00e9caniciens de remplacer une poulie \u00e0 chaque fois qu\u2019une courroie de distribution ou une courroie auxiliaire est remplac\u00e9e et vice versa. Cependant, il y a huit signes avant-coureurs d\u2019une poulie d\u00e9fectueuse \u00e0 observer\u00a0:<\/p>\n

    \n
  1. Balancement \u2013 Faites balancer la poulie d\u2019avant en arri\u00e8re. Il ne devrait y avoir aucun mouvement ou jeu d\u2019un c\u00f4t\u00e9 \u00e0 l\u2019autre.<\/li>\n
  2. Mauvais alignement \u2013 Des poulies mal align\u00e9es causeraient des probl\u00e8mes de bruit de courroie, caus\u00e9s par des roulements us\u00e9s.<\/li>\n
  3. Poulie fissur\u00e9e ou cass\u00e9e \u2013 V\u00e9rifier l\u2019absence de dommages physiques \u00e9vidents.<\/li>\n
  4. Poulie tournant librement \u2013 Faites tourner la poulie avec vos doigts. Tourne-t-elle de plus de 1\/2\u00a0tour? Si c\u2019est le cas, la cause est un manque de graisse dans le roulement, un signe qu\u2019il va bient\u00f4t devenir d\u00e9faillant.<\/li>\n
  5. Roulements gripp\u00e9s \u2013 Une indication que la poulie va bient\u00f4t se bloquer.<\/li>\n
  6. D\u00e9coloration \u2013 Elle peut \u00eatre due \u00e0 un grippage intermittent des roulements de la poulie ou \u00e0 une d\u00e9faillance du tendeur, causant un patinage de la courroie.<\/li>\n
  7. Accumulation de surface \u2013 Indication cl\u00e9 d\u2019un tendeur us\u00e9 causant un patinage de la courroie.<\/li>\n
  8. Usure excessive \u2013 Courante sur les v\u00e9hicules utilis\u00e9s dans des environnements poussi\u00e9reux.<\/li>\n<\/ol>\n
