The excavator slewing bearing is an indispensable structural component for mechanical rotation operations, and what form does the slewing bearing exist in this system structure? How does it work? 1. Slewing bearing The excavator adopts a rotating column type slewing bearing. The rotation angle of the slewing part is generally equal to or less than 180°. It […]
We all know that when the excavator is working, it can twist left and right, front and rear mainly by the slewing mechanism in the machine, and the slewing bearing plays a vital role as an important part of the slewing mechanism. When assembling and overhauling and using and maintaining the excavator slewing bearing, the […]
Crossed roller bearing is a special type of bearing with split inner ring and rotating outer ring. Because of its particularity, it is generally used in industrial robots, as a joint bearing for industrial robots, and can also be used for precision rotation work. Tables, medical instruments, etc. are widely used, so the quality of bearings […]
We all know that the crossed roller bearing is one of the commonly used bearings for robots, and it also plays a vital role. Industrial robots are also very common in industrial production, achieving refinement that humans cannot do, and robots will never tire. Can work all the time, which has played a great role in the […]
With the continuous advancement of science and technology, tractors have entered our daily life, and its application is more and more popular with everyone, and the development trend is showing continuous growth. The use of John Deere tractors has a long history, due to the advantages of turbocharged intercooled engines, shifting transmissions, powerful hydraulic systems, […]
The so-called clutch is to use “off” and “on” to transmit the right amount of power. The clutch consists of a friction plate, a spring plate (the tractor uses a disc spring, and the harvester uses a diaphragm spring), a pressure plate and a power take-off shaft. It is arranged between the engine and the […]
