摘要： A method and apparatus for providing improved lubrication of a spline connection between a PTO driver and a bevel gearbox in which lubricant from the bevel gear housing is directed to a location above and radially outwardly from the splined connection and the apparatus then directs the lubricant flow toward the splined connection by force of gravity. The apparatus is configured to be self-aligning when installed in an existing receptacle in the gearbox housing thereby enabling the apparatus to be conveniently installed in a housing designed to utilize gearbox lubricant to lubricate the splines.

摘要： An improved modular disc cutterhead connecting drive shaft configuration having a means for laterally centering the shaft between adjacent cutterhead modules thereby equalizing engagement on each end of the shaft with the module connectors. Further durability improvement is realized by a structure to radially center the shaft in the shaft receptacles of each module to maintain uniform loading on the shaft/receptacle interface which improves the durability of the connecting drive shaft end connections. Additional connecting shaft durability is provided by a means to lubricate the drive shaft connector connecting interfaces using lubricant reservoirs disposed within the modules.

摘要： A method of gradually relieving pressure in a hydraulic system of a work machine, wherein a pump in fluid communication with the hydraulic system and a fluid reservoir, is operable for pressurizing fluid from the reservoir and pumping the pressurized fluid into the hydraulic system, wherein the pump is restrictive to fluid flow therethrough when not operating, and the hydraulic system includes at least one valve in fluid communication with the work element configured for receiving the pressurized fluid. The valve is controllably operable in at least two operating modes, including a first mode wherein the pressurized fluid can pass therethrough between the pump and the work element or elements, and a second mode wherein the fluid is prevented from passing between the pump and the work element. The method includes operating the valve or valves in the first mode for at least a predetermined time period while the pump is not operating, to allow at least some of any of, the pressurized fluid in the work element to flow through the hydraulic system and gradually drain through the pump to the reservoir so as to reduce any pressure in the hydraulic system and the work element.
