Abstract

A transportation refrigeration unit, which is configured to defrost the evaporator coil of an evaporator, is provided with improvements to a power transfer mechanism (218). The power transfer mechanism (218) incorporates a coupling mechanism (236) that can transfer power from the condenser fan (206) to the evaporator fan (210). In one embodiment, the coupling mechanism (236) is encapsulated in a housing (226), which forms an interior cavity for receiving a lubricating fluid therein. The interior cavity is such that the coupling mechanism (236) is immersed in the lubricating fluid.
