Summary of the invention
The utility model provides a kind of reinforced heavily loaded cranked link chain; Shortcomings such as it is less to have solved original 3214 types heavy duty cranked link chain tensile strength, and antifatigue and wear resistance are relatively poor, and working life is short; Working stability under impact and oscillating load operating mode is durable in use.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of reinforced heavily loaded cranked link chain comprises some bent plate chain links of serial connection successively, and the bent plate chain link comprises sleeve, roller, bearing pin and two cranked plates at least; Roller sleeve is on sleeve, and sleeve is fixed in the narrow end of bent plate chain link, and the position that two cranked plates are positioned at cranked link chain pitch width end is provided with pin shaft hole; Bearing pin is installed between two cranked plates through pin shaft hole, and the bearing pin of a bent plate chain link passes the sleeve of another bent plate chain link in the adjacent two bent plate chain links, and the diameter of bearing pin is 24.5～25.5 millimeters; The height of cranked plate is 63～65 millimeters; Thickness is 14.5～15.5 millimeters, and the cranked plate two ends are circular-arc, and radius of arc is 34～36 millimeters.
The height of cranked plate is 64 millimeters, and thickness is 15 millimeters, and the radius of arc at cranked plate two ends is 35 millimeters, and the diameter of bearing pin is 25 millimeters; One of pin shaft hole on two cranked plates is a circular hole, and another is a non-circular hole; One end of bearing pin is a spindle nose, and the position adjacent with spindle nose is big end, and big end is complementary with non-circular hole, and the other end of bearing pin is provided with lock pin, and the diameter of spindle nose is 32.5～33.5 millimeters; The diameter of spindle nose is 33 millimeters.
The reinforced heavily loaded cranked link chain that the utility model provides, because the height of cranked plate and thickness increase, cranked plate two ends radius of arc strengthens, and has therefore improved the soundness and the torque value of chain greatly, has improved the resistance to shock loads ability.Simultaneously because the pin diameter overstriking, so the wear resistance of chain and pull resistance also be improved, and tensile strength is increased to 580KN by original 476KN.
