Patent number: 11940047Abstract: To provide a simple-structured chain guide assembly frame capable of reliably maintaining a correct positional relationship between a driven sprocket and a sprocket holding portion without the possibility of driven sprocket detachment. The chain guide assembly frame includes a main body having a fixed-guide-side sprocket holding portion and a pivoting-guide-side sprocket holding portion. The fixed-guide-side sprocket holding portion includes a first fixed-guide-side support portion that supports a driven sprocket at a first contact point, and a second fixed-guide-side support portion that supports the driven sprocket at a second contact point located more outside than the first contact point. When the driven sprocket is in an erected state in which the driven sprocket is supported at the first contact point and second contact point, the vector of gravity acting on the gravity center of the driven sprocket points between the first contact point and second contact point.Type: GrantFiled: December 13, 2022Date of Patent: March 26, 2024Assignee: TSUBAKIMOTO CHAIN CO.Inventors: Volkmar Nyga, Seigo Ohsawa, Sung-Hwan Lim, Munehiro Maeda, Yuji Oshima

Patent number: 11933400Abstract: To provide a chain guide assembly frame capable of efficiently collecting the oil that adhered to various parts of the chain guide assembly, and guiding the collected oil to predetermined locations, to allow efficient use of oil, with a simple structure. The chain guide assembly frame includes driven sprocket holding portions, a fixed chain guide, and a pivoting chain guide holding portion on a main body. A drive sprocket holding portion is provided at a position lower than the driven sprocket holding portions. The main body includes a concave and/or convex oil passage that extends from an upper part toward a lower part to guide the oil toward above the drive sprocket holding portion.Type: GrantFiled: December 13, 2022Date of Patent: March 19, 2024Assignee: TSUBAKIMOTO CHAIN CO.Inventors: Volkmar Nyga, Seigo Ohsawa, Sung-Hwan Lim, Munehiro Maeda, Yuji Oshima

Patent number: 11732785Abstract: An object of the present invention is to provide a chain guide mechanism that can readily integrate all the components in a simple structure and enhance work efficiency during assembly or maintenance. The chain guide mechanism of the present invention is configured to be able to integrally support, on a frame, components including a plurality of sprockets, a chain, a fixed chain guide, and a pivoting chain guide. The frame includes a pivoting chain guide holding part that holds a mounting boss of the pivoting chain guide in a state of a loose fit. The pivoting chain guide holding part is configured to allow the mounting boss to be fitted therethrough from one side.Type: GrantFiled: November 5, 2021Date of Patent: August 22, 2023Assignee: TSUBAKIMOTO CHAIN CO.Inventors: Volkmar Nyga, Seigo Ohsawa, Munehiro Maeda, Yuji Oshima
