Abstract
An example shaft assembly includes a metal shaft and a plastic ring element interference-fitted to the metal shaft. The plastic ring element includes a footing proximate to an outer diameter of the metal shaft. The shaft assembly also includes a metal compression ring interference-fitted to the footing of the plastic ring element to apply a radial locking force between the footing and the metal shaft.
Claims15
An apparatus, comprising:
- a metal shaft;
- a plastic ring element interference-fitted to the metal shaft, the plastic ring element comprising a footing proximate to an outer diameter of the metal shaft;
- and
- a metal compression ring interference-fitted to the footing of the plastic ring element to apply a radial locking force between the footing and the metal shaft.
1 more element
A system, comprising:
- a first shaft assembly, comprising:
- a first metal shaft;
- a first plastic gear interference-fitted to the first metal shaft, the first plastic gear comprising a first footing proximate to an outer diameter of the first metal shaft;
- a first metal compression ring interference-fitted to the first footing to apply a first radial locking force between the first footing and the first metal shaft;
- a first plastic pulley interference-fitted to the first metal shaft, the first plastic pulley comprising a second footing proximate to the outer diameter of the first metal shaft;
- and
- a second metal compression ring interference-fitted to the second footing to apply a second radial locking force between the second footing and the first metal shaft;
- a motor comprising a second metal shaft and a second plastic pulley attached to the second metal shaft;
- and
- a coupling belt engaged with the first pulley and the second pulley to couple a torque from the motor to the first metal shaft.
7 more elements
A method, comprising:
- interference-fitting a plastic ring element to a metal shaft, wherein the plastic ring element comprises a footing proximate to an outer diameter of the metal shaft;
- and
- interference-fitting a metal compression ring to the footing, wherein the metal compression ring applies a radial locking force between the footing and the metal shaft.
