Abstract
The utility model provides a reinforced heavy-load bending plate chain, which comprises bending plate chain links sequentially connected in series with each other. Two adjacent bending plate chain links are connected together in such a way that the narrow end of one chain link is connected with the wide end of the other chain link. The narrow end is arranged in the wide end. Each bending plate chain link comprises a cranked plate, a roller, a sleeve and a pin. The roller is sleeved onto the sleeve. The pin is arranged at the wide end of the bending plate chain link through a pin hole. The sleeve is arranged at the narrow end of the bending plate chain link through a sleeve hole. The pin hole is a D-shaped hole. The cross section of the part of the pin arranged inside the pin hole is D-shaped so as to be matched with the pin hole. According to the utility model, the wear resistance and tensile strength of the entire chain of the reinforced heavy-load bending plate chain are improved and the service life of the chain is prolonged. Meanwhile, the entire chain is operated more stably under the condition when a large torque and an impact are provided.
Description
Technical field
The utility model relates to a kind of reinforced heavily loaded cranked link chain, is specially a kind of high 5628 types heavy duty cranked link chain of transmission, bearing load that is used for.
Background technique
Cranked link chain is because its cranked plate structure and loading characteristic, is applicable to the transmission condition that low-speed heave-load, coarse pitch, transmitting torque are big, impact force is arranged, and is widely used in the more abominable occasion of environment such as various large-scale steel workss.Existing 5628 type cranked link chains all are to make according to the ISO3512 standard, and its pitch is 177.8 millimeters, and tensile load is 1890KN.In use, because that bearing pin adopts is cylindrical, columniform bearing pin in use rotates in pin shaft hole easily, particularly under the big situation of transmitting torque, causes this chain at transmission or job insecurity when articles conveyed.Simultaneously, find that in running the bearing pin wearing and tearing are very fast, be subject to impact fatigue and cause premature failure that working life is short again because the bearing pin of this chain adopts the 45# steel to do.
Summary of the invention
Shortcomings such as the utility model provides a kind of reinforced heavily loaded cranked link chain, has solved existing chain poor work stability, and working life is short.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of reinforced heavily loaded cranked link chain; At least comprise the bent plate chain link of serial connection successively; The narrow end of a bent plate chain link is positioned at the wide end of another bent plate chain link in the adjacent two bent plate chain links, and the bent plate chain link comprises cranked plate, roller, sleeve and bearing pin, and roller sleeve is on sleeve; Bearing pin is installed on the wide end of bent plate chain link through pin shaft hole; Sleeve is installed on the narrow end of bent plate chain link through sleeve hole, and pin shaft hole is D shape hole, and the cross section that is positioned at the position of pin shaft hole on the bearing pin is D shape and is complementary with pin shaft hole.
The material selection 20CrMnMo alloyed steel of bearing pin; One end of bearing pin is provided with spindle nose, and the position adjacent with spindle nose is big end, and big end is positioned at pin shaft hole, the lock pin that the other end of bearing pin is provided with perforation and is positioned at perforation.
This reinforced heavily loaded cranked link chain all is designed to D shape with the cross section at the position that is positioned at pin shaft hole on pin shaft hole and the bearing pin, has prevented that bearing pin from rotating in cranked plate.Simultaneously with the material selection 20CrMnMo alloyed steel of bearing pin; Make hardness, tensile strength and the impact resistance of bearing pin all be improved; Thereby the wear resistance and the tensile strength of whole chain have been strengthened; Tensile load has prolonged the working life of chain simultaneously by the corresponding 2190KN that brings up to of original 1890KN.
Description of drawings
The overall structure schematic representation of the reinforced heavily loaded cranked link chain that Fig. 1 provides for the utility model;
Fig. 2 is the design of part schematic representation of this cranked link chain;
Among the figure, 1-cranked plate, 2-roller, 3-bearing pin, 4-sleeve, 5-lock pin, 6-spindle nose, the big end of 7-, 8-pin shaft hole.
Embodiment
The utility model is done bright in detail specifically below in conjunction with accompanying drawing.
The overall structure of the reinforced heavily loaded cranked link chain that the utility model provides is as shown in Figure 1, is made up of the bent plate chain link that is connected in series successively, and the narrow end of a bent plate chain link is positioned at the wide end of another bent plate chain link in the adjacent two bent plate chain links.The bent plate chain link comprises cranked plate 1, roller 2, sleeve 4 and bearing pin 3; As shown in Figure 2; Bearing pin 3 is installed on the wide end of bent plate chain link through the pin shaft hole on the cranked plate 18; Sleeve 4 is installed on the narrow end of bent plate chain link through the sleeve hole on the cranked plate 1, is with roller 2 on the sleeve 4, and the bearing pin 3 of a bent plate chain link passes the sleeve 4 of another bent plate chain link in the adjacent two bent plate chain links.Pin shaft hole 8 is D shape hole; The cross section that is positioned at the position of pin shaft hole 8 on the bearing pin 3 is D shape and is complementary with pin shaft hole; An end of bearing pin 3 is provided with spindle nose 6 in the present embodiment, is to hold 7 greatly with spindle nose 6 adjacent positions, holds 7 to be positioned at pin shaft hole greatly; Its cross section is a D shape, the lock pin 5 that the other end of bearing pin 3 is provided with perforation and is positioned at perforation.The material selection 20CrMnMo alloyed steel of bearing pin.
Cranked link chain is used in this reinforced transmission; Material selection 20CrMnMo alloyed steel with bearing pin; Make hardness, tensile strength and the impact resistance of bearing pin all be improved; Thereby strengthened the wear resistance and the tensile strength of whole chain, tensile load has prolonged the working life of chain simultaneously by the corresponding 2190KN that brings up to of original 1890KN.The cross section that is positioned at the position of pin shaft hole in addition on pin shaft hole and the bearing pin all is designed to D shape, has prevented that bearing pin from rotating in cranked plate, make whole chain at high pulling torque, have work under the operating mode of impact more stable.
