Publication number: 20170138461Abstract: A gearbox assembly with emergency lubrication system includes a housing with an interior including a lubricant sump. The housing includes a breather port and a visual inspection port. The breather port is sized for at least one of relieving internal pressure or admitting air. The visual inspection port is located to allow visual inspection of a component in an interior of the housing. A transmission is disposed within the interior of the housing in fluid communication with the lubricant sump. An emergency lubricant reservoir is in fluid communication with the transmission through the breather port and/or the visual inspection port. A method of retrofitting a gear box assembly with an emergency lubrication system includes removing plugs from visual inspection ports of a gearbox housing, removing a breather from a breather port of the gearbox housing, and installing jet plugs into the respective visual inspection ports and breather port.Type: ApplicationFiled: July 29, 2016Publication date: May 18, 2017Inventors: Anthony G.

Patent number: 5189929Abstract: A transmission gearbox noise control system is operative during normal operations of a transmission system to effectively null temperature variations among selected localized areas of the transmission gearbox housing by utilizing oil jets for cooling/heating thereof, thereby reducing or eliminating differential thermal expansion effects or minor manufacturing errors among such localized areas wherein transmission vibration levels (noise) emanating from the gearbox are abated. The system includes one or more metering valves, a spray rod mounted in combination with each metering valve, an oil reservoir, a fluid pathway for fluidically interconnecting each metering valve to the oil reservoir, at least one pump for circulating oil through the fluid pathway, and a regulating subsystem that is automatically or manually operative to initiate/terminate the operation of each metering valve, to regulate the rate of fluid flow therethrough, and/or to adjust the impingement pattern of the fluid jet discharged therefrom.Type: GrantFiled: March 9, 1992Date of Patent: March 2, 1993Assignee: United Technologies CorporationInventor: Anthony G.
