Abstract
A mechanical self-centring gear extractor device allows the use of a hydraulic cylinder to provide the extraction force, while having self-centring that prevents the accidental opening of the claws, increasing safety during extraction. The extractor includes a first spindle and pulling claws articulated and indirectly coupled to the first spindle, so they can move along it while being supported by it; including a centring device for the claws consisting of connecting rods articulated at one of their ends to intermediate regions of the claws and at the opposite end to a support whose position can be adjusted coaxially along the upper part of the first spindle, including a second spindle coaxial with the first spindle and independent of it in rotation and secured to it in stroke, and including an external thread to thread a handle joined in stroke and independent in rotation of that position adjustable support.
