Bearings play a crucial role in textile machinery, and the following is the relevant introduction:

Application in spinning equipment

Spinning machine: The spindle of a spinning machine is a key component, and the spindle bearing directly affects the quality and production efficiency of the yarn. High-performance miniature bearings are widely used here, and they need to have the characteristics of high speed, low noise and long life. For example, high-precision ball bearings are used to ensure the stability of the spindle when rotating at high speed and reduce the broken end rate of the yarn. The drafting mechanism of a spinning machine is also inseparable from bearings. These bearings need to withstand a certain amount of tension and frequent reciprocating motion, so they require good wear resistance and accuracy retention.

Roving frame: Bearings are required for both the winding mechanism and the transmission mechanism of the roving machine. The bearings of the winding mechanism need to ensure the uniformity and stability of the yarn during the winding process, while the bearings of the transmission mechanism need to withstand large torque and impact loads. For example, bearings with special sealing structures are used to prevent flying flowers and impurities from entering the bearing and affecting its normal operation. The spindle part of the roving machine is also equipped with bearings. These bearings need to maintain good dynamic balance performance while rotating at high speed to reduce yarn hairiness and mass fluctuations.

Applications in weaving equipment

Loom: The spindle bearing of a loom is one of the key components, which needs to bear large radial and axial loads, and at the same time ensure the high-speed operation of the loom and accurate motion control. For example, large cylindrical roller bearings or tapered roller bearings are used to meet the load-bearing requirements and accuracy requirements of the spindle.The weft insertion mechanism and weft beating mechanism of the loom also use a large number of various types of bearings. The bearings of the weft insertion mechanism need to introduce the weft yarn into the weaving mouth quickly and accurately, so they require high speed and high precision. The bearings of the weft insertion mechanism need to bear large impact loads to ensure that the weft yarn is tightly driven into the fabric.

Air jet looms and water jet looms: The air or water jet devices in these new looms require special bearings to ensure their proper operation. These bearings need to operate in high-pressure, high-speed fluid environments, and have good sealing and corrosion resistance. For example, bearings made of special materials and equipped with special sealing devices to prevent fluid leakage and erosion of the bearings.

Application in printing and dyeing equipment

Printing and dyeing machine: The rollers and guide rollers of the printing and dyeing machine need to be fitted with bearings. These bearings need to work in humid, high temperature and chemical environments, so they must have good corrosion resistance and water resistance. For example, bearings made of stainless steel or bearings with special coatings are used to resist the corrosion of the printing and dyeing liquid. The transmission part of the printing and dyeing machine is also inseparable from the support of bearings. The transmission bearing needs to withstand a certain torque and speed, and it is necessary to ensure the smooth operation of the printing and dyeing machine and accurate speed control.

Bearing selection and maintenance points

Selection basis: According to the working characteristics and requirements of textile machinery, choose the appropriate bearing type. For example, for high-speed running parts, ball bearings or air bearings suitable for high speed should be selected; for larger bearing parts, roller bearings should be selected. Considering the factors of the working environment, such as temperature, humidity, chemical corrosion, etc., choose bearings with corresponding protective properties. For example, waterproof bearings should be selected in humid environments, and corrosion-resistant bearings should be selected in chemically corrosive environments. According to the accuracy requirements and installation space of the equipment, choose the appropriate bearing accuracy grade and size specifications.

Maintenance measures: Regularly check the running status of the bearing, including temperature, noise, vibration, etc. By monitoring these parameters, the abnormal condition of the bearing can be detected in time, such as overheating, abnormal noise or excessive vibration, etc., and take corresponding measures for repair or replacement. Keep the bearing clean and lubricated. Regularly clean the bearing to remove dirt and impurities on the surface, and add an appropriate amount of lubricating oil or grease. In the textile environment, flying flowers and fibers are easy to enter the inside of the bearing, so it is necessary to strengthen the sealing and protection of the bearing. For damaged bearings, it is necessary to replace them in time. When replacing the bearing, it is necessary to strictly follow the operating procedures to ensure the installation quality and accuracy. At the same time, the relevant parts should be inspected and maintained to ensure the normal operation of the entire equipment.
