Abstract

Abstract A recirculating ball flat way bearing assembly for facilitating movement between two relatively heavy objects such as, for example, a grinder or milling machine and a way. The components of the bearing assembly include a base plate having recessed side areas and partial opposed bearing tracks on each side surface. A body portion is also provided having recessed sides and partial opposed tracks. A guide member with arcuate ends is adapted to be secured to the base, with the housing then being received over the parts thus assembled so that the partial tracks on the opposed sides of the base plate and on the opposed sides of the housing will, in cooperation with the arcuate ends of the guide member, serve to form an endless run or race for a plurality of opposed balls received therewithin. Means are provided for securing the three components together, and a U-shaped telescoping cover plate is also provided which has its base slid over the top of the body portion and has inturned bottom flanges which partially enclose the bearings when they are in the bottom run, thereby preventing dislodgement of the same.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 120 words
A recirculating bearing assembly comprising; A. a base plate having opposed partial ball runs therein; B. a guide member secured to said base plate; C. a body portion 1. secured to said base plate and said guide member and 2. having opposed partial ball runs which cooperate with said guide member and said partial ball runs of said base plate to form opposed endless ball runs; D. a plurality of ball bearings received in said endless ball runs; and E. a cover plate 1. telescopically received over said body portion, said guide member, and said base plate, and 2. including means for retaining said balls in place for at least a portion of the length of said endless ball runs.
Claim 2
Dependent Claim 120 words
A recirculating bearing assembly comprising; A. a base plate having opposed partial ball runs therein; B. a guide member secured to said base plate; C. a body portion 1. secured to said base plate and said guide member and 2. having opposed partial ball runs which cooperate with said guide member and said partial ball runs of said base plate to form opposed endless ball runs; D. a plurality of ball bearings received in said endless ball runs; and E. a cover plate 1. telescopically received over said body portion, said guide member, and said base plate, and 2. including means for retaining said balls in place for at least a portion of the length of said endless ball runs.
Claim 3
Dependent Claim 43 words
having opposed partial ball runs which cooperate with said guide member and said partial ball runs of said base plate to form opposed endless ball runs; D. a plurality of ball bearings received in said endless ball runs; and E. a cover plate
Claim 4
Dependent Claim 43 words
having opposed partial ball runs which cooperate with said guide member and said partial ball runs of said base plate to form opposed endless ball runs; D. a plurality of ball bearings received in said endless ball runs; and E. a cover plate
Claim 5
Dependent Claim 21 words
including means for retaining said balls in place for at least a portion of the length of said endless ball runs.
Claim 6
Dependent Claim 21 words
including means for retaining said balls in place for at least a portion of the length of said endless ball runs.
Claim 7
Dependent Claim 54 words
The assembly of claim 1 wherein said base plate A. is substantially flat and rectangular in plan; B. has opposed, reduced width portions extending through a portion of its length; and c. said partial ball runs being formed by arcuate shoulders joining the outboard edges of said base plate and said reduced width portions.
Claim 8
Dependent Claim 59 words
The assembly of claim 1 wherein said guide member A. is substantially flat and rectangular in plan; B. has opposed arcuate ends; C. has a width dimension equal to the widest width dimension of said base plate; and D. has a length dimension that is less than the length dimension of said reduced width portions of said base plate.
Claim 9
Dependent Claim 74 words
The assembly of claim 1 wherein said body portion A. has opposed reduced width undercut portions extending through a portion of its length; B. said partial ball runs being formed by arcuate shoulders joining the outboard edges of said body portion and said reduced width portions and the upper wall of said undercut portion; and C. the length of said reduced width undercut portions being slightly greater than the length of said guide member.
Claim 10
Dependent Claim 28 words
The assembly of claim 1 wherein said cover plate A. is U-shaped in cross-sectional configuration; and B. has inturned flanges on the outboard ends of its opposed legs.
