Abstract
An adjustable spacer with a non-hardened intermediate portion therebetween is mountable between a pair of roller bearings also mounted on a shaft such an axle or spindle or the like. The intermediate portion allows the spacer to collapse in the axial direction to maintain desired axial loads on the bearings.
Claims16
An adjustable spacer comprising:
- an annular spacer comprising a first end portion having a face facing away from a second end portion, the face comprising a first material, the first material being a hardened material, and the second end portion located opposite said first end portion, and
- an intermediate portion of said annular spacer located between said first end portion and said second end portion, said intermediate portion comprising a second material of lesser hardness than the first material and more deformable than that first material,
- the annular spacer configured to be mounted coaxially with a bearing assembly and formed separately from the bearing assembly, the bearing assembly comprising rollers and one or more races wherein the annular spacer is separate from the rollers;
- wherein the intermediate portion is formed separately from said first end portion and second end portion and a separate high force section between the first end portion and second end portion, the high force section being configured to withstand a higher axial force than the intermediate section without deformation.
1 more element
An assembly comprising:
- a shaft comprising one or more bearings mounted thereon, the one or more bearings comprising rollers;
- an annular spacer mounted on said shaft, said annular spacer separated from the rollers, said annular spacer comprising a first end portion having a face facing away from a second end portion, the face comprising a first material, the first material being a hardened material, and the second end portion located opposite the first end portion,
- an intermediate portion of said annular spacer, located between said first end portion and said second end portion, said intermediate portion comprising a second material of lesser hardness than the first material and more deformable than the first material and a high force section between the first end portion and second end portion, the high force section being configured to withstand a higher axial force than the intermediate section without deformation.
