Abstract

Inventia se refera la procedee si dispozitive de aplicare a peliculei elastice pe dantura rotilor dintate conice. Procedeul de aplicare a peliculei elastice pe dantura rotilor dintate conice se efectueaza prin aplicarea incontinua a cleiului pe dantura rotii dintate conice prin intermediul a cel putin unei role de aplicare a cleiului si cel putin a unei role de apasare. Noutatea consta in aceea ca se aplica incontinuu clei printr-un dispozitiv de distribuire pe o pelicula elastica si se incleiepelicula elastica pe dantura rotii dintate conice, careia i se comunica o miscare de precesie in jurul punctului de intersectie a axei sale si a generatoarelor rolei de apasare executata conica. Totodata rotii dintate conice i se comunica o miscare de rotatie in jurul axei sale, coordonata cu miscarea ei de precesie. Dispozitivul de aplicare a peliculei elastice pe dantura rotilor dintate conice include un rezervor (12) pentru clei, un mecanism de aplicare incontinua a cleiului, care include cel putin o rola de apasare (10). Latimea rolei (10)este mai mare decat latimea danturii rotii dintate conice (5). Noutatea consta in aceea ca dispozitivul include suplimentar un mecanism de avansare incontinua a peliculei elastice (11) si servomotoare (7, 8) dirijate de un sistem de comanda computerizat si legate cu portrola (2) si cu o masa (6), pe care este instalata roata dintata conica (5). Masa (6) efectueaza o miscare de precesie in jurul punctului de intersectie a generatoarelor dintilor si a axei ei si o miscare de rotatie in jurul axeisale, coordonata cu miscarea ei de precesie. Rolade apasare (10) este executata conica si este fixata in portrola (2) cu posibilitatea reglarii pozitiei ei unghiulare, iar axa ei trece prin punctul de intersectie a generatoarelor dintilor si a axeirotii dintate conice (5).The invention relates to methods and devices for applying the elastic film to the tooth of the conical toothed wheels. The process of applying the elastic film to the tooth of the conical gear wheels is carried out by the continuous application of the glue to the tooth of the conical gear wheel by means of at least one roll of application of the glue and at least of a press roll. The novelty is that the glue is applied continuously through a distribution device on an elastic film and the elastic film is glued to the tooth of the conical gear wheel, which is communicated with a precession movement around the intersection point of its axis and of the roller generators. pressed tapered. At the same time, the conical gear wheel communicates a rotational movement around its axis, coordinated with its precession movement. The device for applying the elastic film to the tooth of the conical gear wheels includes a reservoir (12) for glue, a mechanism for the continuous application of the glue, which includes at least one pressing roller (10). The width of the roller (10) is greater than the width of the gear tooth of the conical gear (5). The novelty is that the device further includes a mechanism for the continuous advancement of the elastic film (11) and servomotors (7, 8) controlled by a computerized control system and linked to the roller (2) and a table (6), on which the conical gear wheel is installed (5). Table (6) performs a precession movement around the intersection point of the tooth and axle generators and a rotational movement around the axis, coordinated with its precession movement. Pressing roller (10) is tapered and is fixed in the roller (2) with the possibility of adjusting its angular position, and its axis passes through the point of intersection of the tooth generators and the tapered tooth axirot (5).
