Speaking of crane slewing bearing wear, the inspection methods are mainly divided into rotary method and tilt method. As for which inspection method to choose, it is mainly determined whether to use the tilt method or the rotary method to measure the bearing wear according to the counterweight configuration of the crane. The basic premise of the […]
Multi-directional die forging is a precision forging technology that performs split-die forging on a multi-directional die forging hydraulic press, and its deformation is mainly extrusion. During multi-directional die forging, two or more punches (or punch cores) pressurize the bad material simultaneously or sequentially from different directions for extrusion or upsetting. Compared with ordinary die forging and split […]
Robot bearings are generally used as joint bearings. The commonly used robot bearings are cross roller bearings and thin-walled bearings with equal cross-section. These two bearings are one of the key accessories for robots. When selecting robot bearings It must be selected according to actual needs, and there are also many precautions when choosing. The […]
One of the commonly used processing equipment in the field of calcium powder processing is hydrated lime equipment. With the strong requirements of the environmental protection department for the powder processing industry to strictly prohibit dust pollution. From a single piece of equipment, it has developed into an entire calcium hydroxide production line that is basically […]
Linear vibrating screen is a multifunctional screening and grading machine. It is widely used in mining, coal, smelting, motor installation process, building materials, refractory materials, light industry, chemical industry and other industries. It has the advantages of large output and high precision. About linear vibrating screen how much do you know about the installation? What should […]
The quality of the roller skin of the briquetting machine directly determines the service life of the briquetting machine. The hardness of the roller skin is the most important parameter to measure the quality of the roller skin of the briquetting machine. The hardness of the roller skin depends on the alloy steel grade selected for the […]
The tank body of the water tank truck is generally made of high-quality carbon steel plate, and the thickness of the plate is generally between 4-6mm. In order to improve the corrosion resistance and service life of the steel tank body, corrosion-resistant materials or stickers can be sprayed on the inner surface of the tank Anti-corrosion lining […]
Shaft forgings should choose different materials and adopt different heat treatment specifications (such as quenching and tempering, normalizing, quenching, etc.) according to different working conditions and use requirements, in order to obtain certain strength, toughness and wear resistance. 45 steel is a commonly used material for shaft forgings. It is cheap and can obtain better cutting […]
During the operation of the excavator, the slewing bearing has to bear a large impact load. When the excavator is tilted, the stress state is even more unfavorable. Generally, when the excavator runs for about 350,000 hours, the slewing bearing of the excavator may be crushed or broken, and the tooth profile wear and broken teeth at […]
Thin-walled crossed roller bearings are composed of crossed cylindrical roller bearings and crossed tapered roller bearings. Due to their particularity and incomparable advantages over other bearings, they are widely used, and some damages will inevitably occur in the use engineering , so what are the damage forms of thin-walled cross rollers? Surface wear and peeling […]
