Abstract
The utility model provides an enhanced heavy-load curved plate roller chain, which comprises a plurality of curved plate chain links in series connection in sequence, wherein each curved plate chain link comprises two curved chain plates with two arc-shaped ends, one ends of the curved plate chain links are wide ends, and the other ends of the curved plate chain links are narrow ends. The portions of the curved chain plates located at the wide ends and the narrow ends are respectively provided with pin shaft holes and sleeve holes. Pin shafts are installed at the wide ends of the curved plate chain links through the pin shaft holes, and rollers are sleeved on sleeves which are fixed at the narrow ends of the curved plate chain links through the sleeve holes. One pin shaft of one of two adjacent curved plate chain links penetrates through the sleeve of the other of the two adjacent curved plate chain links. The firmness, torsion value and impact-resisting loading performance of the chain are improved. Simultaneously, the abrasion resistance and tensile performance of the chain are enhanced, and the tensile strength is increased from the existing 280 kilo Newton to 318 kilo Newton.
Description
Technical field
The utility model relates to a kind of reinforced heavily loaded cranked link chain, is specially a kind of high 2510 types heavy duty cranked link chain of transmission, bearing load that is used for.
Background technique
The heavy duty cranked link chain is widely used in low-speed heave-load, the transmission of impact is arranged; Be specially adapted to oil-well rig, power shovel, building machinery, track-laying vehicle, liquid stirrers, sewage disposal device, textile industry with in the equipment such as mangler, of many uses.Existing 2510 types heavy duty cranked link chain is thinner because of thickness of link plates, and boundary dimension is less, and bearing pin is thinner; Therefore bearing capacity is less; Antifatigue and wear resistance are relatively poor, impact with the oscillating load operating mode under be easy to yield deformation and crack to cause chain to lose efficacy, working life is shorter.
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 2510 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 that two two ends are circular-arc cranked plate; One end of bent plate chain link is wide end, and the other end is narrow end, and the position that is positioned at wide end and narrow end on the cranked plate is respectively equipped with pin shaft hole and sleeve hole; Bearing pin is installed on the wide end of bent plate chain link through pin shaft hole; Roller sleeve is on sleeve, and sleeve is fixed in the narrow end of bent plate chain link through sleeve 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; The diameter of bearing pin is 16.8～17.5 millimeters; The height of cranked plate is 49～51 millimeters, and thickness is 11～13 millimeters, and the radius of arc at cranked plate two ends is 26～28 millimeters.
The height of cranked plate is 50 millimeters, and thickness is 12 millimeters, and cranked plate two ends radius of arc is 27 millimeters; The diameter of bearing pin is 17 millimeters, and an end of bearing pin is a spindle nose, and the other end of bearing pin is provided with lock pin.
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 318KN by original 280KN.
