Abstract

DC60 (17/04/56) in a non-sequential transmission that operates variable speed transmission. From the driving part to the rotating part, followed by the movement of the carrier supporting the rotating part. Change the velocity, which has frictional contact with the driven and follower parts, so that the weight and cost of the pressure regulating cam mechanism can be reduced. to make the ability In the assembly of the prefabricated kit was improved and to achieve the compactness of the adjusting cam mechanism. Controls the pressure in the radial direction of the transmission shaft. to achieve the aforementioned results. The pressure regulating cam mechanism 66 consists of a protrusion 67 arranged as one of the swivel parts 28 and the output swivel 61 and is arranged to protrude to the other side and the Nook 68 is arranged in another part of Swivel part 28 and PTO 61 for loading and contacting The apex of the protrusion 67 in a non-sequential transmission that performs variable speed transmission. From the driving part to the rotating part, followed by the movement of the carrier supporting the rotating part. Change the speed in which there is a frictional contact with the driving and rotating parts. to enable Reduce the weight and cost of the pressure regulating cam mechanism. to make the ability In the assembly of the prefabricated kit was improved and to achieve the compactness of the adjusting cam mechanism. Controls the pressure in the radial direction of the transmission shaft. in order to achieve the aforementioned results The pressure regulating cam mechanism 66 consists of a protrusion 67 arranged as one of the swivel parts 28 and the output swivel 61, and is arranged to protrude to the other side and the Nook 68 is arranged in another part of Swivel part 28 and PTO 61 for loading and contacting The apex of the overhang 67
