Abstract
A dental handpiece (10) has a supporting rotor assembly (15) and ball bearings (13, 14) supporting the rotor. Each ball bearing (13, 14) has a plurality of balls (22). Each bearing (13, 14) has an inner race (20) and an outer race (21) and at least the outer race (21) has an increased outer diameter.
Claims18
A dental handpiece of the type having a rotor supported by a ball bearing assembly, said ball bearing assembly having at least one ball and an inner and an outer race, wherein the improvement comprises a configuration selected from an outer race having a thickened cross section as compared to said inner race, an outer race having a thinner cross section as compared to said inner race, an inner race having a thickened cross section as compared to said outer race, an inner race having a thinner cross section as compared to said outer race, and combinations thereof.
A dental handpiece comprising a rotor, one or more ball bearings supporting said rotor, said ball bearing(s) having a plurality of balls, an inner race, and an outer race, said outer race having a thickened cross section.
A method of fabricating a dental handpiece comprising the step of providing a bearing component of a density selected to provide sound dampening properties to the handpiece.
A method of fabricating a dental handpiece comprising the step of providing a bearing component fabricated from at least two different materials.
A dental handpiece of the type having a rotor supported by a bearing, the improvement comprising adjusting the dimension of at least one of the bearing components using a sleeve thereover or therein.
