Textile Machinery Crossed Roller Bearings
Bearings are an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. In other words, the bearing is used to support the shaft, to guide the shaft or to fix the shaft. The function of the bearing is to support the shaft. The shaft can be rotating or stationary during operation.
Bearings can bear a certain load and have certain strength and rigidity. It has a small friction torque, which makes the rotating parts rotate flexibly. It has a certain bearing accuracy and is the basic requirement to ensure the rotation accuracy of the supported parts.
The bearing of the textile machine is a conical bushing, a lock washer and accessories with a stop ring on the outer diameter of the outer ring and a sealing ring on both sides. Textile machinery crossed roller bearings are mainly used to bear radial and axial combined loads mainly based on radial loads.
In the process of installation and use, the dustproof effect is good and a certain eccentric adjustment can be achieved. The traditional main drive shaft is supported by traditional bearings, such as thrust bearings (when the main drive shaft is vertical), angular contact ball bearings (when the main drive shaft is horizontal), and the performance of these traditional bearings is relatively stable under good working conditions. , but the performance is unstable when the force is uneven. Due to the periodic uneven load, the bearing wears violently and has a short life, so it needs to be replaced frequently.
The mechanism adopts crossed roller bearings, which has many advantages. Since the rollers are arranged in a crossed manner, only one set of crossed roller bearing rings can bear the loads in all directions. Compared with the traditional model, the rigidity is increased by 3 to 4 times.
At the same time, because the inner ring or outer ring of the crossed roller bearing is divided into two structures, the bearing clearance can be adjusted, and even if a preload is applied, high-precision rotational motion can be obtained.
Textile machinery crossed roller bearings are particularly suitable for bearing results with limited radial mounting dimensions. When selecting a bearing without an inner ring or a needle roller and cage assembly, the journal surface and housing hole surface matched with the bearing are directly used as the inner and outer rolling surfaces of the bearing, in order to ensure the load capacity and running performance are the same as those with ferrules.
Textile machinery crossed roller bearings are widely used in machine tools, metallurgical machinery, textile machinery and printing machinery and other mechanical equipment, and can make the mechanical system design very compact and flexible.
