摘要：The invention discloses a means of increasing the maximum allowable load onmechanical elements that roll on each other, such as the members of constant or variablespeed friction drives, ball or roller bearings, rollers, etc. The increased allowable load isachieved by constructing at least one of the elements that roll on each other in twoparts, including a rolling-surface part that is heavily preloaded by one or more additionalparts that induce large compressive stresses on the principal planes normal to therolling-surface. Optimum materials for the rolling- surface part are those that have alarge modulus of resilience, since these materials afford the maximum allowable loadcapacity. In addition to hardened steels, such materials include shape-memory materials,reinforced plastics, bronze and aluminum alloys, and chilled cast iron. Shape-memorymaterials in particular have the advantage of simplifying the supporting structure,especially when the rolling surface is convex.
