ABSTRACT:
A sealed chain is provided that traps lubricant and dust electrostatically. The chain includes an inner plate which is penetrated by a bushing and an outer plate which is penetrated by a pin. The inner and outer plates are connected alternatingly. Between the inner plate and the outer plate, a seal which is coaxial with the bushing and the pin, is provided in contact with the inner and outer plates. The contact area between the seal and the inner plate is smaller than the contact area between the seal and the outer plate. An annular dust hole, which is around the end of the bushing for sliding on the pin is formed on the inner part of the surface of the seal facing the inner plate. When chain bends due to, for example, winding by a sprocket, the seal slides on the inner plate thus, generating electrostatic charge. The end of the bushing 12, which slides on the pin, is encircled by the dust hole, which entraps lubricant electrostatically on sliding surfaces and dust formed by the wear of sliding surfaces.
