  • Chain transmission device
    Patent number: 11927244
    Abstract: When a contact area with a chain guide is reduced by a back surface of a link plate having a convex portion, a friction coefficient in a fluid lubrication region is reduced. A coating film containing 10% or more of chromium is on the link plate. A friction modifier made of a molybdenum compound and including with a lubricating oil promotes generation of MoS2 by the coating film, and prevents an increase in a friction coefficient in a boundary lubrication region.
