Abstract
A tire uniformity machine having a framework for receiving a tire to be tested, a rotatable chuck located within the framework and having a spindle driven by a motor directly coupled to the spindle to selectively cause rotation thereof, whereby the tire is chucked within the chuck assembly and caused to rotate by the motor. The motor is disposed in axial alignment with the spindle.
Claims20
A tire uniformity machine for testing tires, comprising:
- a) a framework for receiving a tire to be tested;
- b) a rotatable chuck assembly located within the framework, the chuck assembly comprising an upper chuck assembly and a lower chuck assembly movable in the axial direction to chuck a tire entering the framework for testing;
- c) said upper chuck assembly including a spindle axially supported by said framework but freely rotatable therein;
- d) a motor assembly directly coupled to said spindle, said motor assembly having an annular stator assembly receiving a portion of said spindle and a rotor assembly rotatable under a field generated by the stator assembly;
- e) said rotor assembly being keyed to said spindle, whereby the tire is chucked within the upper and lower chuck assemblies and caused to rotate by energizing said motor assembly.
