Abstract
A self-retaining wear-pad leveler has a first plate having arms on opposing sides and forming an aperture through the first plate. A rear section is coupled to a rear portion of the first plate and has tabs extending from opposing sides of the rear section. The arms are configured for being retained about a ball of a spherical bearing assembly, and the tabs are configured to cause rotation of the leveler about the bearing when engaged by a component coupled to and rotating about the bearing.
Claims16
A self-retaining wear-pad leveler, comprising:
- a first upper plate having a pair of opposing horizontally-extending arms on opposing sides thereof and forming an aperture therebetween through the first plate, each arm having an upper outer surface defining a convex pivot at a distal end thereof spaced from an opposing lower inner surface of the associated arm;
- and
- a rear section coupled to and downwardly extending from a rear portion of the first plate and having a pair of horizontally-spaced tabs extending from opposing sides of the rear section in a direction away from the convex pivots, the convex pivots being spaced from the rear section;
- wherein the arms are configured for cooperating to receive a portion of a ball of a spherical bearing assembly within the aperture between the arms for retaining the leveler adjacent the ball;
- wherein the tabs are configured to cause rotation of the leveler about a fastener axis coaxial with a fastener vertically extending through the ball of the spherical bearing assembly when the tabs are engaged by a component coupled to and rotating about the fastener axis;
- and
- wherein the leveler is formed from an elastic material, the convex pivots being configured to allow rotation of the component relative to the leveler about a lateral pivot axis intersecting and generally perpendicular to the fastener axis and flexing of the elastic material providing for limited rotation of the component about pivot axes that intersect both the fastener axis and lateral pivot axis and extend away from the lateral pivot axis.

A self-retaining wear-pad leveler, comprising:
- a body comprising opposing upper and lower plates coupled to each other by a rear section vertically extending between rear portions of the upper and lower plates;
- a pair of opposing horizontally-extending arms extending from each upper and lower plate, the arms of each plate being on opposing sides of an aperture defined therebetween, the apertures of the plates being coaxial;
- each arm having a respective upper or lower outer surface defining a convex pivot at a distal end thereof spaced from an opposing respective lower or upper inner surface of the associated arm and from the rear section;
- and
- a pair of horizontally-spaced tabs extending from the rear section in a direction away from the convex pivots;
- wherein the arms of each plate are configured for cooperating to receive a portion of a ball of a spherical bearing assembly within the aperture between the arms of each plate and between the plates for retaining the leveler adjacent the ball;
- wherein the tabs are configured to cause rotation of the body about a fastener axis coaxial with a fastener vertically extending through the ball of the spherical bearing assembly when the tabs are engaged by a component coupled to the bearing assembly and rotating about the fastener axis;
- and
- wherein the leveler is formed from an elastic material, the convex pivots being configured to allow rotation of the component relative to the body about a lateral pivot axis intersecting and generally perpendicular to the fastener axis and flexing of the elastic material providing for limited rotation of the component about pivot axes that intersect both the fastener axis and lateral pivot axis and extend away from the lateral pivot axis.

A wear-pad leveler for a bearing assembly, the assembly having a spherical bearing assembly carried in a pillow block, the leveler comprising:
- a first upper plate having a pair of opposing horizontally-extending arms on opposing sides thereof and forming an aperture therebetween through the first plate, an upper outer surface of each arm having a convex pivot at a distal end thereof, the first plate having an opposing lower inner surface configured for placement adjacent the pillow block, each convex pivot being spaced from the inner surface of the associated arm;
- and
- a rear section coupled to and downwardly extending from a rear portion of the first plate and having a pair of horizontally-spaced tabs extending from opposing sides of the rear section in a direction away from the convex pivots;
- wherein the arms are configured for being retained about a ball of the spherical bearing assembly within the aperture;
- wherein the tabs are configured to cause rotation of the leveler about a fastener axis coaxial with a fastener vertically extending through the ball of the spherical bearing assembly when engaged by a component coupled to and rotating about the bearing assembly;
- and
- wherein the leveler is formed from an elastic material, the convex pivots being configured to allow rotation of the component relative to the leveler about a lateral pivot axis intersecting and generally perpendicular to the fastener axis and flexing of the elastic material providing for limited rotation of the component relative to the pillowblock about pivot axes that intersect both the fastener axis and lateral pivot axis and extend away from the lateral pivot axis.
