Preferably, the piston inner hole is cylindrical bore.
Preferably, the piston inner hole is truncated cone shape endoporus, and the quantity of the truncated cone shape endoporus is two sections, and two sections of truncated cone shapes
Endoporus is arranged in the inside of shank in symmetrical form.
Preferably, the piston inner hole is combined endoporus, and the combined endoporus is cut by one section of cylindrical bore and two sections
Cone-shaped inner hole is combined, and two sections of truncated cone shape endoporus are arranged in the both sides of cylindrical bore in symmetrical form.
Preferably, the shank is made up of mild steel or low-carbon alloy steel.
Preferably, the carburized (case) depth of the shank is 0.6-1.8mm, and the depth of hardening of shank is 1.1-1.3mm.
Compared with prior art, beneficial effects of the present invention are as follows：Pass piston pin in the multiform, by shank
Portion offers piston inner hole, and piston inner hole is for cylindrical bore, truncated cone shape endoporus or by cylindrical bore and truncated cone shape endoporus group
The combined endoporus of synthesis, makes piston hole various shapes, solves and is asked because piston hole shape is more single and awkward
Topic.
