Abstract
A grinding assembly contacts a tire supported by a frame relative to the tire. The grinding assembly includes at least one section, and an axial positioning assembly supporting the at least one section. The axial positioning assembly enables the at least one section to be axially repositioned relative to the tire. The at least one section includes a grinding head, where the grinding head includes a grindstone rotatably supported thereon, the grindstone having rounded shoulders at its axial extremities. The grinding assembly further includes a radial positioning assembly supporting the grinding head for radial movement with respect to the tire.
Claims6
A grinding assembly in a tire uniformity machine for profile grinding a tire having axial and radial dimensions, the grinding assembly comprising
- a first section including a grindstone, and a radial positioning assembly that moves said grindstone relative to the tire in a radial direction and includes a linear actuator that causes the radial movement of said grindstone, said grindstone being rotatable and driven by a motor, wherein said grindstone has a grinding surface adapted to contact the tire, said grinding surface defining a pair of rounded shoulders formed at axial extremities thereof;
- and
- an axial positioning assembly supporting the first section and actuating the first section relative to the tire in an axial direction, said axial positioning assembly including a linear actuator that causes the axial movement of said first section, wherein said axial positioning assembly and said radial positioning assembly are adapted to move said grindstone along a selected profile while said grindstone contacts the tire to shape the tire according to said profile.
A grinding assembly for contacting a tire supported by a frame relative to the tire, the grinding assembly comprising:
- at least one section;
- an axial positioning assembly supporting said at least one section and enabling said at least one section to be axially repositioned relative to the tire, said at least one section including a grinding head, said grinding head including a grindstone rotatably supported thereon, said grindstone having rounded shoulders at its axial extremities;
- a radial positioning assembly supporting said grinding head for radial movement with respect to the tire;
- and a tilt adjuster provided adjacent said grinding head to provide for pivotal movement thereof, wherein said axial positioning assembly includes at least one rail extending along the frame, and a rail carriage supporting said at least one section on said at least one rail, said rail carriage being axially repositionable along said at least one rail.
