Abstract
The utility model discloses a connecting structure with long service life of a chain, which comprises two inner side plates and two outer side plates, wherein the two inner side plates and the two outer side plates are connected through a pin shaft, a sleeve and a ball are sleeved outside the pin shaft in sequence, a thread section is arranged at the top of the pin shaft, a stop nut is screwed at the thread section, and a stop washer is arranged below the stop nut. The utility model improves the connecting structure between the chain links, enhances the strength and greatly prolongs the service life of the chain.
Description
Technical Field
The utility model relates to the field of shapers chains, in particular to a connecting structure with long service life of a chain.
Background
As the running speed of the setting machine is greatly improved, new requirements are put forward on the performance of the chain, the chain which is originally used on a common low-speed setting machine can be used for one year, and the use requirement of 3-6 months can be met when the chain is used on a high-speed setting machine, so that the development of the high-speed setting machine in China is greatly limited, and the use and maintenance cost of printing and dyeing enterprises is improved.
It can be seen from the prior art in fig. 3 that the assembly is realized by the snap ring for the shaft being snapped into the notch of the pin shaft, fastening is not possible, and the snap ring for the shaft needs to bear a large axial load during the running process of the chain, so that the chain is easy to be damaged due to failure.
Disclosure of Invention
The utility model aims to provide a connecting structure with long service life of a chain.
The novel structure of the chain has the advantages that the connecting structure between chain links is improved, the strength is enhanced, and the service life of the chain is greatly prolonged.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
the utility model provides a long service life's of chain connection structure, includes two interior side plates and two exterior side plates, two interior side plates and two exterior side plates pass through the round pin hub connection, the round pin axle is outer to be equipped with sleeve pipe and ball in proper order, round pin axle top department is equipped with the screw thread section, screw thread section department has connect stop nut soon, stop nut below is equipped with the stop washer.
Further, through holes for penetrating through the pin shafts are formed in the two inner side plates and the two outer side plates, and protruding blocks for limiting the pin shafts are arranged at the bottoms of the pin shafts. The original riveting is changed into movable insertion, and the connection and the disassembly are more convenient.
Further, the inner side of the sleeve is flared from the middle to the two ends. And a swinging space is reserved for swinging in the running activity of the chain, so that the swinging angle of the chain is increased.
Further, a bushing is arranged between the sleeve and the pin shaft. The wear resistance is improved.
Further, the lining is made of PEEK. The PEEK material has good wear resistance.
Further, the two inner side plates are provided with protruding parts protruding towards the outer side plate. The contact surface between the inner side plate and the outer side plate is reduced, the abrasion is reduced, and the service life is prolonged.
The beneficial effects of the utility model are as follows:
1. the utility model improves the connecting structure between the chain links, enhances the strength and greatly prolongs the service life of the chain.
2. The wear resistance of the connecting structure is improved by adding the bushing and improving the structure of the inner side plate, and the service life is prolonged.
3. The inner side of the sleeve pipe is flared from the middle to the two ends, a swinging space is reserved for swinging in the running activity of the chain, and the swinging angle of the chain is increased.
4. According to the utility model, the original riveting mode is changed into the active insertion mode by the pin shaft, and the pin shaft is limited by the convex blocks, so that the disassembly and the assembly are easier.
