Publication number: 20240140002Abstract: A forming mold for a drum-shaped shaft tube and a demolding method therefor are provided. The forming mold includes a rotating body having a through hole that passes through the center of the body in an axial direction. The body is divided into multiple parts in a longitudinal direction. The parts are combined in a circumferential direction to form the rotating body. A longitudinal maximum material size of each part is less than a minimum diameter of the through hole. Two side edges of a cross section of at least one part are deflected toward adjacent parts with respect to radial lines at which two end points of an outer arc of the cross section are located, and a chord length of the outer arc of the cross section is less than a chord length of an inner arc of the cross section. The body has a forming section.Type: ApplicationFiled: January 6, 2022Publication date: May 2, 2024Applicant: Shanghai GKN Huayu Driveline Systems Company LimitedInventors: Zhuoxuan ZHU, Fan YANG, Xianggang MENG

Patent number: 11384798Abstract: An angle-adjustable tripod universal joint which has one tripod, three rollers and one universal joint outer part. An inner wall of the universal joint outer part has three roller tracks, and one roller is disposed in each of the roller tracks and rolls along the roller track. The inner cavity of each roller has a rotatably disposed spherical shaft head of the tripod. The inner wall of each roller track has a guiding groove. The peripheral shape of each roller is cylindrical. The bottom surface of the guiding groove is a plane surface, and two side surfaces of the guiding groove are flat surfaces perpendicular to the plane surface. The peripheral surface of each roller is partially inserted into the corresponding guiding groove, and the peripheral surface of the roller is tangent to the corresponding plane surface.Type: GrantFiled: March 3, 2017Date of Patent: July 12, 2022Assignee: Shanghai GKN Huayu Driveline Systems Company LimitedInventors: Xiaotian Li, Tangjun Peng, Delin Wang, Zhenghua Zhang, Lu Jin
