Function and classification of active disk finished product components

　　The active disc finished component is suitable for scraper conveyors and scraper conveyor systems in coal mines. The sprocket chain is driven by a sprocket. The sprocket assembly is subjected not only to static loads but also to pulsating and impact loads, making it a vulnerable part. Therefore, the sprocket is made of steel. Now, let's learn about the functions and classifications of the active disc finished component!

　　The active disc finished component is processed and formed in the machining center, with the tooth surface hardened. The sprocket forging must have no defects such as cracks, sandwiches, wrinkles, forging injuries, or chuck slag on the surface. After 6 months of operation, the sprocket assembly is installed at 180 degrees, evenly installed, and the wear on both sides of the chain teeth is uniform.

　　Functions of the active disc finished component assembly:

　　The active disc finished component is an important transmission part of the scraper conveyor and conveyor. When the high-power motor transmits torque to the sprocket shaft assembly, the sprocket drives the scraper blades to pull the coal.

　　Composition of the active disc finished component assembly:

　　The active disc finished component is installed on the head frame and end frame of the head gear. It mainly consists of sprockets, shafts, bearings, housings, retaining tools, end caps, seals (floating seals, skeleton oil seals, O-rings, dust seals), etc.

　　Classification of the active disc finished component group:

　　The sprocket assembly of the scraper conveyor consists of sprockets and rollers. The structure of the sprocket assembly is divided into two types: partial and integrated.

　　a segmented sprocket assembly consists of one sprocket and two semicircular segmented rollers, fixed with bolts. There are two sprockets at both ends of the roller, forming a double-sided chain structure. The roller holes are connected to the low-speed shaft of the reducer and the ends of the blind shaft. The advantage of the segmented structure is that when the teeth wear out, only the sprocket needs to be replaced, and the roller does not need to be replaced.

　　b the difference between the integrated sprocket assembly and the separated roller is that the roller and sprocket are welded together. The integrated sprocket assembly is easy to disassemble and maintain.

　　According to different usage positions, it is divided into cylinder head sprocket shaft assembly and tail rocket shaft assembly.

　　The dynamic sprocket combination of the embedded scraper conveyor is usually a concave chain. Compared with the convex chain, it can adapt to domestic annular chains, significantly reducing chain wear. Even if the main link becomes larger, it will not lose the chain, greatly extending the chain replacement cycle.

　　The corresponding chain tension adjustment uses a worm gear reduction self-locking stretching mechanism, which saves labor in adjustment, is easy to operate, and ensures simultaneous stretching on both sides. At the same time, the high-strength mining circular chain of the embedded scraper conveyor is a conveyor chain with a large load capacity and wear resistance. According to the characteristics of material segmentation, it prevents the return chain and scraper from separating from the material, causing a sharp increase in oil quantity and clogging the mechanical warehouse with blocked chain scraper accidents.

　　Moreover, the embedded scraper conveyor is also equipped with an overload protection device. If the chain is overloaded, it will automatically stop running and send an alarm signal. To reduce the wear of the scraper and chain of the buried scraper conveyor, basalt tin is added internally, which not only has a much longer lifespan than metal linings but also has less friction resistance than metal linings.

　　The buried scraper conveyor is equipped with a chain alarm device, which can promptly detect chain breakage, chain failure, automatic shutdown, and alarm signals. By adding a unique backpack drive mechanism, it not only increases power, saves space, but also facilitates installation. The embedded scraper conveyor consists of a screw shaft with spiral blades, a cylinder body, and the installation of bearings. Considering the importance of its tightness, the sealing between the screw shaft and the bearing uses double oil seals. The oil seal prevents fine powder from entering the bearing seat, while the right sealing component prevents the smooth lubricating grease of the bearing from flowing into the oil cylinder. The oil seal is also known as a rotary lip seal.
