Abstract

"DISPOSITIVO DE EXERCER FORçA DE PROPULSãO PARA TENSOR E MéTODO PARA INSPECIONAR O REFERIDO DISPOSITIVO". Prover um dispositivo para exercer força de propulsão que seja silencioso e superior em durabilidade para ser usado em um tensor para exercer uma força de tração na correia de acionamento sem fim tal como corrente de came ou similares em um motor de combustão interna. Um dispositivo para exercer força de propulsão (20) em um tensor para pressionar de uma correia de acionamento sem fim (10) via um tensor na direção de tensão para exercer uma força de tração na correia de acionamento sem fim (10) via um elemento de propulsão que compreende: um corpo de pressionar (30) encostado ao elemento propulsado na extremidade frontal e provido com uma rosca (34) na porção traseira dele; o corpo de pressionar sendo suportado pelo invólucro (21) a fim de não girar em volta do eixo, mas para mover-se ao longo do eixo; um eixo giratório tendo uma porção rosqueada (28) para ser parafusada na rosca (34); um elemento de mancal (25) interposto entre a porção traseira do eixo giratório (26) e o invólucro (21) para suportar o eixo giratório (26) a fim de ser capaz de girar em volta do eixo enquanto suporta uma força de reação de propulsão exercida no eixo giratório (26); e uma mola (39) provida entre o invólucro (21) e o eixo giratório (26) para impulsionar o corpo de pressionar (30) para frente; caracterizado em que a força de pressionar e torque de retorno são ajustados dentro da região compatível interposta entre o limite de desgaste permissível para o qual um ou ambos, do tensor e da correia de acionamento sem fim (10), podem resistir ao uso e o limite de barulho permissível de barulho gerado quando a correia de acionamento sem fim (10) está sendo direcionada para frente no mapa bidimensional usando a força de pressionar que é uma força de projeção do corpo de pressionar impulsionada pela mola (39) e torque de retorno requerido para girar o eixo giratório enquanto supera a força de impulso e força de fricção da mola para forçar o corpo de pressionar (30) a ser retraído em um estado em que uma carga constante é exercida no corpo de pressionar conforme variáveis."DEVICE TO EXERCISE DRIVE FOR TENSOR AND METHOD TO INSPECT THIS DEVICE". Provide a propelling force exerting device that is quiet and superior in durability to be used on a tensioner to exert a tensile force on the endless drive belt such as cam chain or the like in an internal combustion engine. A device for exerting propulsive force (20) on a tensioning tensioner of an endless drive belt (10) via a tensioner in the tension direction for exerting a tensile force on the endless drive belt (10) via an element a propulsion unit comprising: a pressing body (30) abutting the propelled element at the front end and provided with a thread (34) at the rear portion thereof; the pressing body being supported by the housing (21) in order not to rotate about the axis but to move along the axis; a rotary shaft having a threaded portion (28) to be screwed into the thread (34); a bearing element (25) interposed between the rear portion of the rotary shaft (26) and the housing (21) to support the rotary shaft (26) in order to be able to rotate around the shaft while supporting a reaction force of propulsion exerted on the rotary axis (26); and a spring (39) provided between the housing (21) and the rotary shaft (26) for pushing the pressing body (30) forward; characterized in that the pressing force and return torque are adjusted within the compatible region interposed between the allowable wear limit to which one or both of the tensioner and endless drive belt (10) can withstand wear and tear. allowable noise limit of noise generated when the endless drive belt (10) is being directed forward on the two-dimensional map using the push force which is a spring-driven push body projection force (39) and return torque required to rotate the pivot shaft while exceeding the thrust force and spring friction force to force the pressing body (30) to be retracted in a state in which a constant load is exerted on the pressing body according to variables.
