Process and device for elastic film application onto the bevel gear teeth

The invention relates to processes and devices for elastic film application onto the bevel gear teeth.The process for elastic film application onto the bevel gear teeth is realized by continuous application of glue onto the bevel gear teeth by means of at least a glue applying roller and at least a presser roller. Novelty consists in that it is continuously applied glue through a glue distribution device onto an elastic film and the elastic film is glued onto the teeth of the bevel gear, which is communicated a precession gear around the point of intersection of its axis and of the generators of the pressure roller made conic. Concomitantly, the bevel gear is communicated a rotary motion around its axis, coordinated with the precession motion thereof.The device for elastic film application onto the bevel gear teeth includes a capacity (12) for glue, a glue continuous feeding mechanism, including at least a pressure roller (10). The width of the roller (10) is greater than the width of the teeth of the bevel gear (5). Novelty consists in that the device additionally includes an elastic film continuous feeding mechanism (11) and servomotors (7, 8), controlled by a computer control system and joined with the roller holder (2) and a table (6), onto which it is installed the bevel gear (5). The table (6) carries out a precession motion around the point of intersection of the teeth generators and its axis and a rotary motion around its axis, coordinated with the precession motion thereof. The pressure roller (10) is made conic and fixed into the holder (2) with the possibility of controlling its angular position, and its axis passes through the point of intersection of the teeth generators and of the axis of the bevel gear (5). Invenţia se referă la procedee şi dispozitive de aplicare a peliculei elastice pe dantura roţilor dinţate conice.Procedeul de aplicare a peliculei elastice pe dantura roţilor dinţate conice se efectuează prin aplicarea incontinuă a cleiului pe dantura roţii dinţate conice prin intermediul a cel puţin unei role de aplicare a cleiului şi cel puţin a unei role de apăsare. Noutatea constă în aceea că se aplică încontinuu clei printr-un dispozitiv de distribuire pe o peliculă elastică şi se încleie pelicula elastică pe dantura roţii dinţate conice, căreia i se comunică o mişcare de precesie în jurul punctului de intersecţie a axei sale şi a generatoarelor rolei de apăsare executată conică. Totodată roţii dinţate conice i se comunică o mişcare
