Abstract
The invention disclosed includes a gear puller system in which a vibrating means is used to loosen the target gear in a machine making it easier to remove or pull the gear from a housing, such as a hub. In one embodiment, the vibrator transmits vibrations along the shaft of the gear puller. In second vibration, the vibrating means transmits vibrations through the machine to the gear puller.
Claims13
A gear pulling system comprising:
- a gear puller including;
- a shaft having a first end and a second end, wherein said shaft is threaded for most of its length between said first end and said second end and includes an unthreaded portion in between said first and second ends;
- a first tightening means positioned at said first end;
- a claw, said claw having a crosspiece, said crosspiece defining an orifice having an internal thread, wherein said orifice is threadably engaged with said threaded shaft;
- at least two claw legs pivotally attached to said crosspiece;
- and,
- a vibration means, said vibration means operatively attached to said shaft to generate vibrations through said shaft by means of an electrical connection and a frequency mechanism wherein said vibration means is directly connected to said shaft at said unthreaded portion.
