Abstract
Systems and methods for removing a bearing assembly from a shaft include a steam ring, the steam ring being a ring shaped member. The steam ring has an inner bore sized to circumscribe the shaft. A lip ring extends from a first end face of the steam ring and has an inner diameter length that is greater than an outer diameter length. A steam inlet port extends through a sidewall of the steam ring. A steam outlet port extends through the sidewall of the steam ring at a location spaced apart from the steam inlet port.

A system for removing a bearing assembly from a shaft, the system including:
- a steam ring, the steam ring being a ring shaped member and having:
- an inner bore sized to circumscribe the shaft;
- a lip ring, the lip ring extending from a first end face of the steam ring and having an inner diameter length that is greater than an outer diameter length;
- a steam inlet port extending through a sidewall of the steam ring;
- and
- a steam outlet port extending through the sidewall of the steam ring at a location spaced apart from the steam inlet port.
A system for removing a bearing assembly from a shaft, the system including:
- a steam ring, the steam ring being a ring shaped member and having:
- an inner bore circumscribing the shaft;
- a lip ring, the lip ring extending from a first end face of the steam ring, the first end face having an outer face surface radially outward of the lip ring and an inner face surface radially inward of the lip ring, and where the lip ring and the inner face surface define a steam circulation path along an inner race of the bearing assembly;
- a steam inlet port extending through a sidewall of the steam ring to the steam circulation path;
- a steam outlet port extending from the steam circulation path through the sidewall of the steam ring at a location spaced apart from the steam inlet port;
- and
- a steam source connected to the steam inlet port.
A method for removing a bearing assembly from a shaft, the method including:
- circumscribing the shaft with a steam ring, the steam ring being a ring shaped member and having:
- an inner bore;
- a lip ring, the lip ring extending from a first end face of the steam ring and having an inner diameter length that is greater than an outer diameter length;
- a steam inlet port extending through a sidewall of the steam ring;
- and
- a steam outlet port extending through the sidewall of the steam ring at a location spaced apart from the steam inlet port;
- and
- providing steam to the steam inlet port to heat the bearing assembly.
