Abstract

The utility model provides a reinforced transmission bending plate roller 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 wide end of one chain link is connected with the narrow end of the other chain link. Pins are arranged at the wide ends of the bending plate chain links through pin holes in the bending plate roller chain. Sleeves are arranged at the narrow ends of the bending plate chain links through sleeve holes in the bending plate roller chain. The sleeve are sheathed with rollers. The pin holes are D-shaped holes. The cross sections of the two ends of the pins are D-shaped so as to be matched with the pin holes. The pin of one chain link of two adjacent bending plate chain links passes through the sleeve of the other chain link. The reinforced transmission bending plate roller chain is stable in working performance, long in service life and high in durability.

Description

Cranked link chain is used in a kind of reinforced transmission
Technical field
The utility model relates to a kind of reinforced transmission and uses cranked link chain, is specially a kind of high 4020 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 4020 its pitches of type cranked link chain are 127 millimeters, and bent plate thickness is 15.7 millimeters, and the bent plate height is 91.9 millimeters, and tensile load is 990KN.In use, because its tensile strength is too small, fatigue failure even fracture often take place in chain; Simultaneously because bearing pin adopts cylindrical; Columniform bearing pin in use rotates in pin shaft hole easily, so the working stability of this chain is not good, and working life is not long.
Summary of the invention
Shortcomings such as the utility model provides a kind of reinforced transmission to use 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:
Cranked link chain is used in a kind of reinforced transmission; At least comprise the bent plate chain link of serial connection successively; The wide end of a bent plate chain link is connected with the narrow end of another bent plate chain link in the adjacent two bent plate chain links, and bearing pin is installed on the wide end of bent plate chain link through the pin shaft hole on the cranked plate, and sleeve is installed on the narrow end of bent plate chain link through the sleeve hole on the cranked plate; Be with roller on the sleeve; Pin shaft hole is D shape hole, and the cross section at the two ends of bearing pin is D shape and all is complementary with 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.
The thickness of cranked plate is 16 millimeters, and the height of cranked plate is 92.2 millimeters.
One end of bearing pin is provided with spindle nose, and the position adjacent with spindle nose is big end, and the cross section of big end is a D shape, the lock pin that the other end of bearing pin is provided with perforation and is positioned at perforation.
Cranked link chain is used in this reinforced transmission; With the thickness of cranked plate and highly all corresponding increasing; Tensile load is by the corresponding 1200KN that brings up to of original 990KN, and the cross section with the two ends of bearing pin is designed to D shape simultaneously, has prevented that bearing pin from rotating in the cranked plate hole; Therefore the working stability of this chain improves greatly, and operating life also prolongs to some extent simultaneously.
Description of drawings
The reinforced transmission that Fig. 1 provides for the utility model is with the overall structure schematic representation of cranked link chain;
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 reinforced transmission that the utility model provides is as shown in Figure 1 with the overall structure of cranked link chain, is made up of the bent plate chain link that is connected in series successively, and the wide end of a bent plate chain link is connected with the narrow 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, and 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; Pin shaft hole 8 is D shape hole, and the cross section at the two ends of bearing pin 3 is D shape and all is complementary with pin shaft hole 8.The height of cranked plate 1 is 92.2 millimeters in the present embodiment, and thickness is 16 millimeters.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; One end of bearing pin 3 is provided with spindle nose 6; With spindle nose 6 adjacent positions is big end 7, holding 7 cross section greatly is D shape, the lock pin 5 that the other end of bearing pin 3 is provided with perforation and is positioned at perforation.
Cranked link chain is used in this reinforced transmission, and an end of bearing pin is a spindle nose, and the other end is provided with lock pin, can prevent that cranked plate from expanding outwardly; The cross section that is positioned at the pin shaft hole position on pin shaft hole and the bearing pin is D shape, can prevent relatively rotating between bearing pin and the cranked plate; With the thickness of cranked plate and highly corresponding increase, improved the tensile load of chain greatly simultaneously, therefore cranked link chain is used in this reinforced transmission, and not only stable work in work, and long service life is durable in use.
