TSR
Since the introduction of the Taper Secure Radial (TSR) Series rims and wheels in 1992, customers worldwide in mining and industrial operations have experienced significant benefits. Some of the benefits are: vastly increased rim and component life, improved tire life and performance, better air retention and less equipment downtime which leads to increased production.
Component flexing and movement are common in standard rim designs. This movement causes premature rim and component failures. Any damage in the o-ring sealing area, or the bead seat band and lock-ring mating area will lead to air loss in the tire. Movement of rim components also leads to excessive tire bead movement, damaging the tire's beads, causing air loss and premature tire failures.
The taper design of the TSR secures all rim components in place. It eliminates any movement or flexing of the rim components (side rings, rim base, bead seat band, lock ring, and o-ring). The beads of the tire are secure and stable. Air loss and the problems associated with it are eliminated.
In a typical 57” rim assembly, there is only 138 square inches of contact between the flange and back section. At 120-psi tire inflation pressure this works out to 7600-psi pressure.
A 57” TSR rim assembly at 120-psi inflation pressure has 2.5 times more contact area between the flange and the backsection. As a result, the contact pressure is reduced to only 1350-psi.
The taper design gives the side rings more surface area over which to seat. The increased contact area spreads the forces and pressures out evenly across the components. The thickness of this area gives the side ring the stability to react against the forces of the tire. The fully machined taper ensures an even distribution of the contact stresses.
