Spiral Ingot Bearing Protection and Protection Method Summary: Wuxi Huge Textile Machinery Co., Ltd. Xuanwei Zhoufei Shimei DZ Series Spindle Bearings are mainly used for chemical fiber blended yarns and yarns. The use of textile machinery spindles and cotton spinning companies to better protect and protect is very important. The author's point of view to contact the user to talk about the use of the spindle bearing series of products to protect and protect the aspects of the spindle bearing function features liquid dynamic pressure bearing common shaft shell with shaft /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
DZ series spindle bearings are mainly used for textile machinery spindles such as cotton, wool, hemp, enamel, chemical fiber, pure spinning and blending spinning machines and twisting machines. For cotton spinning companies; how to better use, protect and protect It is very important that these special items are here. The author is mainly from the point of view of the product producer and the user's application; some methods and opinions on the application, protection and protection of the products of the spindle bearing series.
The function and characteristics of the spindle bearing are used as special bearings for textiles; the layout of the bearing is quite special. It uses a single-row radial short cylindrical roller arrangement without inner ring; it is a high-speed fine bearing that accepts pure radial load. All the bearings after installation are still In the open case; considering the requirements of installation, packaging, transportation and user reinstallation; the current spindle bearing uses a special anti-rust oil. It not only has outstanding anti-rust function; it also ensures that the bearing enters the end user. It is not easy to break the scatter when installing the link.
Because the single-row radial short round roller is selected; therefore, the series bearing is rigid; it has large radial load and high production precision; the rotation is sensitive and stable; the noise is low; the customary high-speed operation, the layout is simple; the power consumption is low, the maintenance protection is convenient .
The current specifications for the products of the spindle bearing series are still: FZ/T92025 1994 "DZ series spindle bearings" textile industry specifications.
The cage with new reinforced nylon data has the following features: First, the new cage is made of engineering plastic PA66 glass fiber reinforced nylon, and second, it is made by injection molding; the cage is of good craftsmanship; the scale and shape are stable. The third is that the cage with nylon material has a certain self-smooth effect, and the fourth is to optimize the depiction of the layout of the pocket; it can make the roller undulate and reduce during the high-speed operation. Jurisdiction file.
The correct application of the spindle bearing is the first; in the case of the bearing housing bearing hole size, shape, accuracy is not good; the bearing will be affected by it; can not play the best function. For example; if the cooperation part bearing housing hole size accuracy and If the shape accuracy is not good, the bearing outer ring deformation will be formed; the roundness of the bearing inner hole will be deteriorated, if the shoulder accuracy is not good; the bearing outer ring and the roller will be skewed; the weight will gather the load; the bearing fatigue life will be reduced; Will cause damage to the cage, sintering, if the accuracy of the spindle bearing of the inner ring of the bearing is not good; such as accuracy in scale, roundness, cylindricity, waviness, roughness, azimuth, etc.; The addition of the entire set of spindle oscillation values.
Secondly; the complete set of bearings through the strict fine selection before installation; so the user before the application; scattered bearing parts have not been selected from the beginning, can not be used interchangeably.
Third; on the problem of the removal of spindle bearings and spindles. Because the spindle layout is compact; there are many other parts in the spindle cavity; their cleanliness also affects the cleanliness of the bearing cavity. Thus; before assembly Pre-scraping the parts of the ingots; installing the assembly in the future; and then finishing the ingots including the bearings is a reasonable process.
Fourth; the bearing should not be bumped and impacted during installation; bumps and impacts easily form a bump between the bearing parts; causing the bearing to fail.
Fifth; when the bearing seat is crimped, it is necessary to pay attention to the control of the viewpoint, strength and other elements of the curling; to prevent the unfavorable forming of the bearing parts from deformation.
Sixth; about the bearing that has passed the anti-rust period or the long-term storage time; it may show rust or the rust-proof oil is dry and the roller sticks to death.
The correct protection and protection of the bearing is the first priority; the spindle bearing in the spindle should be sufficient to ensure smoothness during operation; and smooth oil should be added according to the actual application; it is not long-term oil cut. Therefore, regarding the user company; Good and more suitable spindle smooth oil. The new special spindle oil can significantly improve the smooth function; extend the oil change cycle; extend the service life of the spindle and bearing; also has better anti-rust and anti-corrosion functions.
Secondly; the bearing of the reinforced nylon data holder should be used, the operating temperature should be lower than 120 °C, and the cooking should be prohibited.
Others; should pay attention to the method when removing the spindle protection; prevent damage and scratch the appearance of the roller. It is necessary to remove the residue of the bearing part as much as possible; it is better to use the method of scouring and suctioning the inside of the spindle to remove the residual oil. The dumping type causes the waste to accumulate and remains in the bearing part; it causes problems such as noise and wear failure of the bearing.
