The service standard of mine ring chain is: (1) bear tensile force; (2) fatigue caused by pulsating beverage load; (3) Friction and damage between the ring chain and the ring chain, between the ring chain and the sprocket chain, between the ring chain and the thick plate and the groove help;

1. Service standard for ring chains for mining

The service standard of mine ring chain is:

(1) bear the tensile force;

(2) fatigue caused by pulsating beverage load;

(3) Friction and damage between the ring chain and the ring chain, between the ring chain and the sprocket chain, between the ring chain and the thick plate and the groove help;

(4) by coal powder, rock powder and wet and cold gas effect caused by erosion.

2. Failure analysis of mine ring chain

The breaking mode of mining ring chain is roughly divided into:

(1) the load of the chain link exceeds the breaking load of its own foundation pile and leads to premature rupture. This kind of rupture is mostly caused in the shortcomings of the chain shoulder or straight arm, such as the gap welding heat hazard area and some round rod cracks;

(2) After running for a period of time, the chain link does not break the load, resulting in the fracture caused by fatigue, which is mostly generated at the joint of the straight arm and the arc of the chain.

3. Provisions for ring chains for mining purposes

(1) In the same material and cross section, to have a higher bearing capacity;

(2) In addition to having a large breaking load, there should be a large tensile strength;

(3) The effect of the maximum bearing capacity requires a small deformation in order to ensure a good fit;

(4) high fatigue limit;

(5) high wear resistance;

(6) High ductility and great ability to digest and absorb impact loads;

(7) Geometric drawing specifications comply with engineering drawings.

Analysis of Chinese chain industry quality work

Since 2003, Chinese chain industry still maintains rapid development speed. In 2004, under the guidance of the state macro-control policy, the Chinese chain industry changed the previous development thinking of heavy production and heavy market, adjusted and optimized the product structure, and gradually realized the transformation of economic growth mode. At the same time, Chinese chain industry has been developing high-tech content and high value-added new products, improving product quality and enhancing the competitiveness of Chinese chain industry in the international market as an important development strategy of enterprises. In recent years, in the chain drive association, chain drive standardization technical committee, the national chain quality supervision

The chain driving mechanism includes a chain

The utility model relates to a chain drive mechanism on a NC drilling machine used for blind hole processing in a perforating gun barrel. The utility model relates to a chain drive mechanism to solve the problem that the distance between the cutter head and the main sprocket on the NC drilling machine used for blind hole processing in a perforating gun barrel is long, and the single chain drive is easy to loosen and break the chain. The transmission motor drives the transmission pair gear to rotate through the transmission gear shaft and the transmission main gear, and the main sprocket shaft then rotates and drives the main sprocket to rotate. The chain drive and the centralized heating mechanism of the plastic bottle blowing machine, the chain drive mechanism comprises a chain and a number of transmission gears, the chain is fixed with a number of chain block components, including the chain block, each chain block

Force analysis and structure optimization of connecting link

The connecting link is the connecting part of the scraper chain of coal mine scraper conveyor, which plays an important role in the traction chain. Due to the special working conditions, traction chain link often occur fracture phenomenon, once the chain link is broken, the whole equipment is in a state of paralysis, seriously affecting the normal production of coal mine. Not only the economy suffered serious losses, but also the search for the broken chain and link are carried out on the side of the coal wall, there is a certain risk, and even cause personal accidents. The connecting link has a high breaking capacity, and a high reliability is required in the work. So the study of connecting link link change. Previous analyses of the butt link did not consider the effect of the cylindrical pin, and
