The invention discloses a
maintenance system for gear flaw detection. The
system comprises a base, a case and a flaw
detector, the case is fixedly mounted at the upper end of the base, a PLC is fixedly mounted on one side of the outer wall of the base, a box door is hinged to one side of the outer wall of the
machine box, a first motor and two bearing seats are fixedly installed in one side of thebottom end in the
machine box, a
threaded rod is rotatably installed between the two sets of bearing seats, a threaded sliding seat is installed on the outer portion of the
threaded rod in a threadedmode, and a supporting rod is fixedly installed at the upper end of the threaded sliding seat through a containing and carrying plate. According to the invention, a driving gear is installed, staticnondestructive flaw detection operation can be carried out on the gear, hidden structural dangers existing in gear production and
machining can be found in time, structural flaw detection operation can be carried out on the gear under the dynamic operation condition, and therefore the stress and deformation conditions of the gear structure under the operation state can be mastered, and the detection effect is effectively improved.
