Abstract
"MéTODO DE FABRICAçãO DE UMA PLACA RETENTORA DE AMORTECEDOR DE VIBRAçãO TORCIONAL EM UMA Só PEçA, E, PLACA RETENTORA" é apresentado um método de fabricação de uma placa retentora de amortecedora de vibração torcional inteiriça (20) para um conversor de torque (26). A placa retentora inclui uma periferia anular (36) encurvada na forma de uma acanaladura genericamente em forma de C (46) para reter pelo menos uma mola (56). O método inclui as seguintes etapas. Primeiramente, a placa retentora (20) é estampada basicamente para formar um segmento de placa central (34), uma periferia anular (36), e uma abertura de cubo (44). A seguir, a periferia anular da placa retentora é pré-encurvada. A placa é então tratada termicamente para aumentar as propriedades físicas da placa retentora. A mola é disposta dentro da periferia anular pré-encurvada. Finalmente, a periferia anular da placa retentora é completamente encurvada em uma acanaladura genericamente em forma de C para substancialmente circundar a mola desse prevenindo que a mola seja removida da acanaladura em forma de C da placa retentora durante a operação da placa retentora."METHOD OF MANUFACTURING A TORCIONAL VIBRATION SHOCK HOLDER PLATE IN ONE PIECE, E, HOLDER PLATE" presents a method of manufacturing a retaining plate for torsional vibration damper (20) for a torque converter (26) . The retaining plate includes an annular periphery (36) curved in the form of a generally C-shaped groove (46) to retain at least one spring (56). The method includes the following steps. First, the retaining plate (20) is stamped basically to form a central plate segment (34), an annular periphery (36), and a hub opening (44). Then, the annular periphery of the retaining plate is pre-curved. The plate is then heat treated to increase the physical properties of the retaining plate. The spring is disposed within the pre-curved annular periphery. Finally, the annular periphery of the retaining plate is completely curved in a generally C-shaped groove to substantially surround the spring thereof preventing the spring from being removed from the retaining plate's C-shaped groove during operation of the retaining plate.
