The gear track of the scraper is installed on the gear track seat of the middle slot, which is the track supported and guided by the shearer. It is an important support point for the stability of normal coal mining for the shearer to realize the haulage of the shearer relying on the tooth and rail pin tooth of the scraper. Therefore, scraper conveyor parts manufacturers remind you to use a more durable scraper conveyor gear track. At present, the teeth and rails of the plate scraper in the market mostly adopt the structural forms such as integral die forging, integral casting, split welding and forging welding. Fission welding type rack and forge welding type rack is a compound structure, by putting the two track plate and pin gear processing compound into an organic whole, due to welding and machining accuracy cannot be guaranteed, so prone to open the phenomenon such as welding, fracture, wear, these two kinds of structure of the rack can't meet the need of the high-power coal winning machine supporting the fully mechanized coal face. Although the whole cast gear track avoids the problem of gear track cracking to some extent, the casting strength obviously fails to meet the use requirements, which affects the coal mining efficiency. The integral die forging gear track is strengthened by heat treatment of alloy structural steel. It adopts die forging technology and completes the manufacturing process by a series of procedures such as forging, forming, trimming and punching. Therefore, the overall strength of the tooth and rail of the scraper is higher than the above three technologies, the pin tooth position and tooth shape processing accuracy is more guaranteed, can make the shearer and the tooth and rail better mesh, the impact force in the use process is also smaller, for the large power shearer, conveyor supporting use to provide a guarantee. The integral die forged gear rail can meet the required performance requirements and is more durable. After reading, you choose and buy which scraper gear rail heart roughly spectrum!
