Abstract
Antifriction bearings for transmitting forces between race members movable rectilinearly and rotatively relative to each other in which the bearing elements move to and from bearing positions in closed loop paths that are continuous and extend uninterruptedly for substantially the full effective bearing length of spaced lands on one of the race members.
Claims14
In a rectilinear and rotary motion bearing having relatively spaced first and second race members,
- one of said members having relatively spaced bearing lands,
- rollable bearing elements in said bearing for movement between said first and second race members and movable into and out of engagement with said bearing lands,
- retainer means between and movable relative to said first and second race members and having a plurality of closed loop paths for retaining said bearing elements between said first and second race members, the invention comprising
- said closed loop paths each having a pathway defined therein through which the bearing elements project for rectilinear and rotary rolling engagement with said first and second race members,
- said bearing lands being relatively spaced by recesses defined in said one member,
- and said lands and closed loop paths being unequal in number with said closed loop path extending continuously for substantially the full effective length of said bearing lands,
- each said closed loop path having two of said pathways each of which is relatively spaced from the other an extent greater than the extent of each of said bearing lands and less than each of said recesses.
In a bearing having inner and outer circular race members coaxially arranged for relative arcuate and rectilinear movement,
- one of said members having alternating bearing lands and recesses defined therein,
- rollable bearing elements between said race members,
- means retaining certain of said bearing elements coaxially between said race members and for movement each in a respective one of a plurality of closed loop paths in which each of said paths is relatively spaced from the other,
- each said closed loop path having at least two relatively spaced pathways through which the bearing elements therein project for bearing engagement between said race members,
- and said closed loop paths and lands being unequal in number with the relative space between the center line of each pathway of their respective closed loop path being greater than the extent of each said bearing land and less than each of said recesses.
In a bearing having inner and outer race members coaxially arranged for relative rectilinear and rotatable movement,
- rollable bearing elements between said members for bearing engagement therewith,
- means retaining said bearing elements for movement in a plurality of respective closed loop paths coaxially between said members and for rectilinear and rotary movement relative thereto,
- bearing lands and non-bearing recesses alternately defined on one of said race members for bearing and non-bearing engagement respectively with said bearing elements,
- each said respective closed loop path having a pathway through which the bearing elements in said respective closed loop path project for engagement with said race members,
- said pathway of one closed loop path being spaced an extent from the pathway of the next adjacent closed loop path different than the arcuate extent of each of said bearing lands,
- and said closed loop paths and bearing lands being unequal in number.
