Abstract
A torque transmission device has a pinion that includes a plurality of rollers that mesh with a plurality of teeth of an output. Each roller is supported by a bearing having rotating bearing elements. A clearance compensation for the diametrical difference between a diameter of each roller and an inscribed diameter of the associated rotating bearing elements is included in the plurality of teeth of the output such that there is no interference between the plurality of rollers and the plurality of teeth.
Claims7
A torque transmission device comprising, in combination:
- an output having teeth;
- and
- a pinion having a plurality of rollers that mesh with the teeth of the output, wherein each roller is supported by a bearing having rotating bearing elements and each bearing includes a clearance between the roller and the rotating bearing elements, wherein the clearance creates an interference between at least one roller and at least one tooth of the teeth of the output, and wherein the teeth of the output include a clearance compensation that is equal to a diametrical difference between a diameter of each roller and an inscribed diameter of the associated rotating bearing elements.
A method of compensating for dimensional clearances in a torque transmission device, comprising
- providing a rack having a plurality of teeth;
- and
- providing a pinion having a plurality of rollers that mesh with the plurality of teeth of the rack;
- providing a bearing to rotationally support each roller, with each bearing having rotating bearing elements, wherein each bearing includes a dimensional clearance between each roller and the rotating bearing elements that creates an interference between at least one roller and at least one tooth of the plurality of teeth of the rack;
- and
- providing a clearance compensation between the plurality of rollers and the bearings of the plurality of rollers of the pinion,
- wherein the clearance compensation is based upon a diametrical difference between a diameter of each roller and an inscribed diameter of associated rotating bearing elements.
