Jaw crusher we should be familiar with, well, jaw crusher parts you know how much?
1.The frame with broken jaw is mainly used to support eccentric shaft (main shaft), jaw plate and bear crushing force. Commonly used cast steel (such as ZG35) is cast as a whole or assembled separately, or welded with thick steel plate. In order to increase the rigidity, there are longitudinal and transverse stiffeners on the outside.
2. Jaw broken eccentric shaft (also known as the main shaft) supports the moving jaw and flywheel, bears bending and torsion, and acts as a crank. The eccentricity is generally io-35mm, which is a more valuable part of the machine. It is usually forged with high-strength and high-quality alloy steels such as 42mnmov, 30mnmob and 34mnmo, and 45 steel is also used for small ones. Generally, it needs to be tempered.
3. Jaw broken plate (broken plate) and guard plate. The jaw plate with teeth is installed in front of the moving jaw working face and the opposite frame, and the side guard plates without teeth are installed on the two inner walls of the frame to form a square cone crushing chamber. Jaw plate and guard plate are directly in contact with crushed materials, and they are subject to strong crushing extrusion pressure and friction and wear, so they are generally made of wear-resistant materials. ZGMn13 or expensive high manganese nickel molybdenum steel is commonly used. In small jaw crushers of small and medium-sized factories, white cast iron is also commonly used instead.
4. The function of jaw breaking thrust plate (lining plate) is to support the moving jaw and transmit the crushing force to the rear wall of the rack. When the rear end of the thrust plate is equipped with an adjusting device, it can be used to adjust the size of the discharge port. In design, gray cast iron material is often used to determine the size according to the condition that it can break by itself when it is overloaded. The thrust plate is also a kind of safety device, which can automatically stop working when the overload is not allowed, so as to increase the discharge port, so as to protect valuable parts such as moving jaw, eccentric shaft and frame from being damaged. Therefore, do not change the material and size of the original drawing without special reasons. A kind of
5. The working surface of jaw breaking jaw is equipped with jaw plate (crushing plate), which is usually cast with ZG45 and zc35. The upper part is supported by eccentric shaft. Some bearings are sliding bearings, some are rolling bearings, and the lower part is supported by thrust plate. The working surface of the moving jaw is inlaid with a broken plate with teeth, which is fastened with bolts, and attention should be paid to prevent loosening. In order to reduce the weight and increase the chipping property, the movable jaw is made into a box shape, and the bottom of the movable jaw is pulled by the hook head pull rod.
