Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, 4 and 5, the disassembling tool for the diesel engine gear shaft is provided with a pull shaft 1; the pull shaft 1 is provided with a threaded rod 11 which is matched with a threaded hole 41 in the diesel engine gear shaft; the threaded rod 11 is of a hollow structure; the top end of the threaded rod 11 is provided with a pull shaft head 12; the shaft drawing head 12 is in an elliptic structure with two corresponding side wall surfaces being planes 13; the center of the pull shaft head 12 is provided with a blind hole 16 for connecting with a hydraulic connecting pipeline; the upper end face of the blind hole is opened; the inner wall surface of the blind hole is provided with an internal thread 14; a pull shaft through hole communicated with the blind hole is formed in the center of the bottom surface of the blind hole 16; the blind hole 16 is communicated with a central through hole of a diesel engine gear shaft through the pull shaft through hole 15 and a central through hole of the threaded rod to form a lubricating oil passage; the disassembling tool is also provided with a positioning sleeve 2 sleeved on a diesel engine gear shaft 4; with reference to fig. 2, the positioning sleeve 2 is a cylindrical structure with an opening at one end; the closed end of the positioning sleeve 2 is provided with a through hole 21 for a threaded rod to pass through; the two sides of the opening end of the positioning sleeve are symmetrically provided with observation windows 22.
Referring to fig. 5, the lower portion of the threaded hole inside the diesel gear shaft has an oil passage 42 communicated therewith; the diameter of the oil passage 42 is smaller than that of the threaded hole; an oil channel hole 44 is arranged corresponding to the oil channel 42, and an oil groove 43 is processed on the shell of the diesel engine gear shaft; the oil groove 43 is divided into two parts.
And a bolt in threaded fit with the threaded rod is also arranged between the pull shaft head and the positioning sleeve.
