摘要： A gear case seal is provided for use with a traction motor. The seal may have an arcuate body with an outer annular layer forming a centrally located channel extending along its length, and an inner annular layer bonded to the outer annular layer along opposing axial edges so as to close off the centrally located channel. The body may also have a middle layer disposed within the centrally located channel and made from a material different than a material of the inner and outer layers.
