With the continuous growth of the demand for coal, coal mining machinery is also developing rapidly. Second, as an important transmission component of the main equipment in coal mining, mining high-strength ring chain is also developing rapidly. Because it is a key part of the scraper conveyor in coal mine, so its quality and performance have a profound impact on the amount of coal mining and the efficiency of the equipment.

With the increasing demand for coal, coal mining machinery is also developing rapidly. As an important transmission component of the main equipment in coal mining, mining ring chain is also developing rapidly. Because it is a key part of the scraper conveyor in coal mine, so its quality and performance have a profound impact on the amount of coal mining and the efficiency of the equipment.

High strength ring chain for mining has been developing, which can be divided into the following four aspects: the development of steel for high strength ring chain for mining, the development of heat treatment technology, the optimization of ring size and shape, different chain design and the development of chain making technology. Due to these developments, the mechanical properties and reliability of high-strength ring chain used in mining have been greatly improved. The specifications and mechanical properties of ring chain produced by some advanced chain manufacturing enterprises in the world have far exceeded the current international standard DIN22252.

Early foreign low-level mining ring chain steel is mostly carbon manganese steel, low carbon content, little alloying element content, low hardenability, chain diameter is generally < 019mm. In the 1970s, a series of high - grade chain steel of Mn - Ni - Cr - Mo was developed. In the late 1980s, 23MnNiMoCr54 steel was developed. In recent years, due to the continuous improvement of the performance requirements and chain specifications of mechanized coal mining in coal mines, some foreign chain companies closely follow the changes and development of the market, developed some new steel, these steel performance is more stable, better quality, higher than 23MnNiMoCr54 steel.

Shandong Deyao Electromechanical Technology Co., Ltd. is located at the foot of Mount Tai, the first of the five mountains, belonging to the ancient civilized town of Dawenkou, the company was founded in 2005, is Tai 'an city and even Shandong Province within the ring chain production leading enterprises. The products mainly include high strength ring chain, mine ring chain, mine compact chain, ship anchor chain, etc. Welcome to consult and guide.

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
