Description
Sistema de apoyo y rodadura para tambor desmoldeador en fundición.Support and rolling system for drum casting mold release.
El objeto de la presente invención es un sistema de apoyo y rodadura para tambor desmoldeador en fundición de nueva estructuración, con cuyo empleo se reduce el número de paradas por mantenimiento, así como la duración de cada parada.The object of the present invention is a system support and rolling for new mold casting drum structuring, whose use reduces the number of stops by maintenance, as well as the duration of each stop.
Ya se conocen tambores para desmoldear objetos fundidos: Son de grandes dimensiones y van apoyados con posibilidad de girar alrededor de su eje por lo que requieren dos o más zonas de apoyo con posibilidad de rodadura, una de las cuales, al menos, tiene que incluir elementos motrices.Drums for unmolding objects are already known cast: They are large and are supported with possibility to rotate around its axis so it requires two or more zones of support with possibility of rolling, one of which, at least, It has to include driving elements.
Las Patentes EP 0 066 931 y E 0 326 876 entre otras, constituyen ejemplos claros del actual estado de la técnica.EP Patents 0 066 931 and E 0 326 876 between others are clear examples of the current state of technique.
Un problema básico de estos tambores de tecnología convencional radica en el rápido deterioro de sus apoyos: Dado que se trata de aparatos de grandes dimensiones, las vibraciones a que se someten sus apoyos (y que se transmiten a sus rodamientos) son enormes.A basic problem of these drums of conventional technology lies in the rapid deterioration of its supports: Since these are large appliances, the vibrations to which your supports are subjected (and transmitted to your bearings) are huge.
La tecnología convencional soluciona este problema recubriendo las ruedas de apoyo con material elastomérico, lo cual reduce vibraciones y alarga la vida de los rodamientos, pero entonces lo que se deteriora rápidamente es el material elastomérico y requiere un muy frecuente recambio: En la práctica se traslada el problema de sustituir el rodamiento por sustituir el elastómero.Conventional technology solves this problem coating the support wheels with elastomeric material, which reduces vibrations and lengthens the life of the bearings, but then what deteriorates rapidly is the material elastomeric and requires a very frequent replacement: In practice the problem of replacing the bearing is replaced by replacing the elastomer

Se describe a continuación un ejemplo de realización práctica, no limitativa, del presente invento.An example of practical, non-limiting embodiment of the present invention.
La presente invención trata de un sistema de apoyo y rodadura para tambor desmoldeador en fundición.The present invention concerns a system of support and rolling for casting mold release drum.
El tambor (1) para enfriar y desmoldear objetos fundidos ya es conocido: Se mantiene apoyado en grupos de apoyo (2) y gira alrededor de su eje (11), para lo cual, al menos uno de dichos apoyos (2) es también motriz.The drum (1) to cool and unmold objects Fades is already known: It remains supported by support groups (2) and rotates around its axis (11), for which, at least one of said supports (2) is also motive.
Dichos grupos de apoyo (2) son grupos motorreductores independientes, que apoyan en lugar fijo (F_{1}).These support groups (2) are groups independent gearmotors, which support in a fixed place (F_ {1}).
Los soportes (21) y el grupo motor-reductor (22) se disponen coaxialmente en cada grupo de apoyo (2). Entre ambos se ubica, al menos, una rueda (23), de apoyo y motriz para el tambor (1).The supports (21) and the group motor-reducer (22) are coaxially arranged in each support group (2). Between them there is at least one wheel (23), support and drive for the drum (1).
De conformidad con la invención -ver figura 1- cada grupo de apoyo (2) emplea, al menos, tres puntos de apoyo: Dos (P_{1}), (P_{2}) para apoyo directo de los soportes (21) y otro (P_{3}) para apoyo del grupo motor-reductor (22).In accordance with the invention -see figure 1- Each support group (2) employs at least three support points: Two (P_ {1}), (P_ {2}) for direct support of the supports (21) and other (P_ {3}) for motor-reducer group support (22).
De conformidad con la invención -ver figura 2- cada rueda (23) consta de un alma metálica (23a) y una camisa exterior (23b), también metálica, y concretamente de un material metálico con una carga de rotura superior a 100 Nw/mm^{2}, lo cual evita –o reduce considerablemente- un deterioro prematuro de la(s) rueda(s) (23). En la figura 2 se observan tres ruedas (23), pero este número puede variar (aumentar/disminuir) sin alterar la esencia del invento.In accordance with the invention -see figure 2- each wheel (23) consists of a metal core (23a) and a shirt exterior (23b), also metallic, and specifically of a material metallic with a breaking load greater than 100 Nw / mm2, which which avoids - or considerably reduces - a premature deterioration of the wheel (s) (23). Figure 2 shows three wheels (23), but this number may vary (increase / decrease) without alter the essence of the invention.
De conformidad con la invención los rodamientos (21a) de cada soporte (21) son rodamientos de rodillos (21b) cilíndricos oscilantes siendo cilíndrica la superficie exterior de su aro externo (21c) -ver figura 3- con lo que los mayores esfuerzos debidos a las vibraciones los soportan directamente los rodillos (21b) y no el aro exterior (21c), lo cual evita -o reduce considerablemente- un deterioro prematuro del soporte (21).In accordance with the invention the bearings (21a) of each support (21) are roller bearings (21b) oscillating cylindrical being the outer surface of cylindrical its outer ring (21c) -see figure 3- with what the older efforts due to vibrations are directly supported by rollers (21b) and not the outer ring (21c), which avoids -or reduces considerably - a premature deterioration of the support (21).
