Abstract
A traction motor suspension bearing and assembly wherein a bearing liner having grooves cooperating with a member on an axle surface to restrict lubricant losses.
Claims25
A bearing for use with a traction motor suspension assembly wherein a member is carried on the axle to reduce the oil losses through said bearing comprising,
- a bearing body having an arcuate bearing surface defining an axial sleeve portion adapted to engage a surface of said axle,
- said bearing body having a first recessed groove formed circumferentially in the periphery of said bearing surface into which said member extends and is rotated with said axle,
- a passage communicating with said first groove, said passage being located to allow excess lubricant which enters said first groove to be moved into said passage by rotation of said member with said axle,
- a second recessed groove in the periphery of said bearing surface, and,
- means connecting said second groove with said first groove to allow excess lubricant from said second groove to move to said first groove.
2 more elements
A bearing comprising,
- a arcuate bearing surface sized to engage a journal,
- a first groove in which a rotating member may move during rotation of a journal,
- a passage communicating with said first groove to allow a lubricant to be moved away from said groove and into said passage by said member during rotation thereof,
- a second groove, and
- means connecting said second groove to said first groove so lubricant collecting in said second groove can move into said first groove and be moved by said member into said passage.
2 more elements
An assembly comprising,
- a rotatable shaft,
- a bearing mounted in supporting relation with respect to said shaft, said bearing having a first groove and a second groove therein opening toward said shaft,
- a passage communicating with said first groove through which lubricant can move,
- means carried by said shaft which extends beyond the diameter of said shaft and into said first groove, said means rotating with said shaft to move lubricant in said first groove toward said passage, and
- means connecting said first groove to said second groove to aid in returning lubricant from said said second groove to said first groove.
2 more elements
In combination in an assembly for traction motors,
- an axle,
- a bearing,
- an axle cap having a lubricant reservoir therein mounted to aid in holding said bearing in contact with said axle,
- both said bearing and said axle cap having window openings therein which generally register with one another and open to said reservoir,
- said bearing having a circumferential first groove in the bore thereof and a passage communicating between said groove and said reservoir.
- said bearing also having a second circumferential groove positioned axially outwardly of said first groove and means connecting said first and second grooves together to allow lubricant collecting in said second groove to move into said first groove, and
- a member carried by said axle and extending into said first groove to aid in moving lubricant from said first groove to said passage and thence to said lubricant reservoir as said member is rotated by said axle.
