摘要： A gear box or the like adapted for prolonged effective use in a harsh and/or corrosive environment such as found in the chemical industry and are in which salt water is prevalent. Components of the gear box are provided with protective polymer coatings which are low friction and impervious to attack from the environment and materials used therein. Exterior surfaces of the housing are coated with a polymer that also withstands impact from foreign objects as exemplified by polyamides, epoxies and fluorocarbons with nylon being preferred. Other components such as the input shaft, bushings and the like are preferably coated with one or more layers of fluorocarbon polymers, with layers in contact with the component including a thermosettable binder component such as a phenolic. Certain coating thicknesses are most preferred.

摘要： A novel bushing for use with industrial equipment such as a gear box is disclosed as being particularly adapted for long time usage in an adverse corrosive environment, such as salt water. The bushing is coated on all exposed surfaces with a fluorocarbon poller which is tough, resilient and is unaffected by the harsh environment. Preferably, the fluorocarbon is a polytetrafluoroethylene, and if applied as a first layer directly to the metal bushing, also includes a thermoset binder material such as a phenolic. Top or outer coatings may also be applied and such coatings do not contain a binder. A mechanical advantage is provided for assembly and disassembly as well as protection for the element.
