Description

Mute chain

Technical Field

The utility model discloses be applied to industrial field, specifically be a silence formula chain.

Background

The chain is generally a metallic chain ring or ring, and is used for mechanical transmission and traction. Chains used to obstruct traffic paths (e.g. in streets, rivers or estuary entrances), chains used mechanically. In the same kind of products, the chain product series is divided according to the basic structure of the chain, i.e. according to the shape of the elements, the parts and the positions meshed with the chain, the size proportion among the parts and the like. The types of chains are many, but their basic structures are only the following ones, and others are all variations of these ones. As can be seen from the above chain structures, most of the chains are composed of chain plates, chain pins, shaft sleeves and the like. Other types of chains only change the chain plates according to different requirements, some chain plates are provided with scrapers, some chain plates are provided with guide bearings, and other chain plates are provided with rollers and the like, which are used for modification in different application occasions. The conventional chain generates a part of noise due to frictional vibration generated during use.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a silence formula chain to solve the problem of proposing among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a silent chain, includes the outer link joint, be equipped with two spliced poles on the outer link joint, two the inner chain has been cup jointed on the spliced pole, the inner chain includes the inner link joint, be equipped with two siphunculus on the inner link joint, be equipped with logical sound hole on the siphunculus, the sleeve has been cup jointed on the siphunculus, be equipped with the bloop on the sleeve, the end of siphunculus is equipped with the inner chain apron, the end of spliced pole is equipped with the outer chain apron.

Preferably, the connection mode between the inner chain plate and the inner chain cover plate can be welding.

Preferably, the silencing holes and the sound through holes are uniformly distributed on the sleeve and the through pipe.

Preferably, the surfaces of the inner chain cover plate and the inner chain plate are polished.

Preferably, lubricating oil is arranged at the contact position of the connecting column and the through pipe.

Compared with the prior art, the beneficial effects of the utility model are that: holes with different calibers are added at different positions in the sound transmission process to form a structure with resistance to noise reduction, so that the purpose of noise reduction is achieved while noise is generated by the chain, and the noise in the use environment is reduced.

Fig. 1 is a design structure diagram of the present invention.

Wherein the connecting column 1, the outer chain plate 2, the inner chain 3, the inner chain plate 31, the through pipe 32, the ventilation hole 33, the sleeve 34, the muffling hole 35, the inner chain cover plate 36 and the outer chain cover plate 4.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a silent chain, includes outer link joint 2, be equipped with two spliced poles 1 on the outer link joint 2, two the inner chain 3 has been cup jointed on the spliced pole 1, inner chain 3 includes inner link joint 31, be equipped with two siphunculus 32 on the inner link joint 31, be equipped with logical sound hole 33 on the siphunculus 32, sleeve 34 has been cup jointed on the siphunculus 32, be equipped with the bloop 35 on the sleeve 34, the end of siphunculus 32 is equipped with inner chain apron 36, the end of spliced pole 1 is equipped with outer chain apron 4.

Specifically, the connection between the inner link plate 31 and the inner link cover plate 36 may be a weld.

The universality of the equipment is improved, and the equipment adopts different connection modes in different production environments and different use environments.

Specifically, the muffling hole 35 and the vent hole 33 are uniformly distributed on the sleeve 34 and the through pipe 32.

The silencing effect is more uniform and reliable.

Specifically, the surfaces of the inner chain cover plate 36 and the inner chain plate 31 are polished.

The friction force between the parts is small, so that the equipment runs more smoothly during running.

Specifically, the contact position of the connecting column 1 and the through pipe 32 is provided with lubricating oil.

The working principle is as follows: when the chain is in operation, the connecting column 1 and the through pipe 32 rub to generate noise, and the through pipe 32 is provided with the sound through holes 33, and the sound eliminating holes 35 are formed in the outer sleeve 34, so that a resistant sound eliminating condition can be formed in the sound transmission process, the purpose of eliminating the noise while the chain generates the noise, and the noise in the use environment is reduced.
