Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
144 words
Disengaging member for a clutch or the like comprising a sliding sleeve formed with a bore, a bearing mounted on said sliding sleeve and including a revolving race and a non-revolving race, stop means for limiting axial movement of said nonrevolving race with respect to said sliding sleeve, said revolving race having contact surfaces for engagement by radially extending disengaging elements of a clutch, and retaining means effective in axial direction of said sliding sleeve for ensuring retention of said bearing on said sliding sleeve, said retaining means being disposed in a position relative to said stop means to provide axial and unbiased free play of said bearing on said sliding sleeve, and said bearing having an inner race having a diameter greater than at least a portion of said sliding sleeve to provide radial free play of said bearing on said sliding sleeve.
Claim 2
Dependent Claim
144 words
Disengaging member for a clutch or the like comprising a sliding sleeve formed with a bore, a bearing mounted on said sliding sleeve and including a revolving race and a non-revolving race, stop means for limiting axial movement of said nonrevolving race with respect to said sliding sleeve, said revolving race having contact surfaces for engagement by radially extending disengaging elements of a clutch, and retaining means effective in axial direction of said sliding sleeve for ensuring retention of said bearing on said sliding sleeve, said retaining means being disposed in a position relative to said stop means to provide axial and unbiased free play of said bearing on said sliding sleeve, and said bearing having an inner race having a diameter greater than at least a portion of said sliding sleeve to provide radial free play of said bearing on said sliding sleeve.
