Abstract
A lubrication system for the spline connection and generator bearing of a high speed aircraft generator which utilizes a split ring seal and quad o-ring is disclosed. The split ring seal retards lubricant flow so that there is an accumulation in the area of the splined connection which prevents wear of the splines. The retardation also forces oil to a bearing lubrication hole.
Claims6
A spline and bearing lubrication system for use in high speed aircraft generator drive systems having:
- a stub shaft having external splines for transmitting power,
- a power receiving internally splined tube having a splined portion and a smooth portion,
- a bearing located around said power receiving internally splined tube,
- a splined connection formed by the stub shaft external spline and the power receiving internally splined tube, said connection having first and second ends,
- a source of high pressure engine lubricating oil which is supplied to said first end of said splined connection, the improvement comprising:
- a lubrication hole connecting said first side of said splined connection to said generator bearing for supplying said engine lubricating oil to said generator bearing and
- means located at said second end of said splined connection and secured to said power receiving splined tube for retarding the flow of said oil across said splined connection, for forcing a portion of said oil into said lubrication hole and for preventing fretting or corrosion of said splined connection.
