Abstract
A seal for sealing around a drive shaft protruded through a hole or opening in a liquid containing box. The seal includes a seal housing secured to the box and having a center opening, and a flinger sleeve secured to the drive shaft and projected through the center opening of the seal housing. The sleeve includes an inner wrap-around flange that extends axially inward and radially outward of the center opening to repel liquid directed towards the box hole. A clamping ring provides radial location setting of the seal housing relative to the shaft and axial location setting of the sleeve relative to the seal housing while also providing clamping of the sleeve to the drive shaft.
Claims12
A seal assembly for sealing around a rotatable drive shaft extended through a hole in a gear box, said gear box defining an interior wherein liquid lubricant is sprayed around the gear box interior, said seal assembly comprising:
- a seal mount and a flinger sleeve, said seal mount mountable to said gear box and as mounted defining an opening surrounding said shaft extended through said hole;
- said flinger sleeve mountable to said shaft and as mounted protruded through said opening of said seal mount and in desired spaced radial and axial relation to said seal mount;
- and
- said seal mount and flinger sleeve cooperatively configured as so mounted with the sleeve including an inner wrap-around flange rotatable with rotation of said shaft and which wraps axially inward and radially outward of said opening of said seal mount whereby lubricant directed towards said seal mount opening is repelled away from the opening upon contact with said rotating flange.
A seal assembly for sealing an opening through an opening in a wall of a gear box, said opening providing protrusion of a drive shaft as between an interior and exterior of the gear box and wherein liquid lubricant is sprayed throughout the interior and is desirably prevented from leaking through said opening, said seal assembly comprising:
- a seal housing, a flinger sleeve and a clamping ring;
- said seal housing mountable to a wall of the gear box and defining an opening surrounding the drive shaft protruded through said gear box opening;
- said flinger sleeve mountable to said drive shaft and as mounted, protruded through said opening of said housing, said flinger sleeve configured to have an inner flange extended axially inwardly and radially outwardly of said opening of the seal housing;
- said clamping ring and said seal housing cooperatively configured to have mateable rib and lip components and said clamping ring and said flinger sleeve cooperatively configured to have mateable abutting edges whereby with the clamping ring mounted to the drive shaft and the rib and lip component mated, the seal mount can be desirably located for securement to the gear box, and as secured with the edges of the ring and sleeve in abutment, the sleeve can be secured to said shaft for desirable spacing of the flange axially relative to the seal mount.
