首页:公司动态 >> 托辊振动轴承的优势
1、外观特点 1. Appearance characteristics A.滚动体直径加大,滚动体长度加大。B.保持架由外圈挡边引导滚子,减少对滚子的作用力。 C.采用内圈挡边引导滚子,改善滚子运转。 D.圆柱滚子轴承保持架采用整体式结构,强度大大提高。 E.调心轴承外径设计有油槽油孔,润滑效果好。 The diameter of the A. roller increases and the length of the rolling body increases. The B. cage is guided by rollers on the outer ring to reduce the force on the roller. C. uses inner ring to guide rollers to improve roller operation. D. cylindrical roller bearing cage adopts integral structure, and its strength is greatly improved. The outer diameter of the E. aligning bearing is designed with oil groove oil hole, and the lubrication effect is good. 2、选用材料 2. Selection of materials A.内外圈及滚动体采用真空脱气轴承钢,耐疲劳性能好。B.保持架采用铝铁锰青铜材料,强度高,弹性好,耐磨性能更好。 A. inner and outer rings and rolling bodies adopt vacuum degassing bearing steel, which has good fatigue resistance. B. cage adopts aluminum iron manganese bronze material, with high strength, good elasticity and better wear resistance. 3、热处理方式 3. Heat treatment A.内外圈采用贝-马混合淬火或马氏淬火+高温回火,硬度均匀,内应力小;韧性好,抗冲击和振动。 B.在150C温度以内工作时,稳定性好。 The A. inner and outer rings are made of shell and horse mixed quenching or martensitic quenching and high tempering, with uniform hardness, small internal stress, good toughness, impact resistance and vibration. When B. works at the temperature of 150C, the stability is good. 4、公差及制造工艺 4, tolerance and manufacturing process A.严格按P6级精度标准制造,尤其内外径公差度很小。 B.滚动体尺寸相互差≤0.002 C.圆柱滚子外径有凸度修行,避免应力集中。 D.滚动表面超精处理,光洁度高。 A. is strictly manufactured according to P6 level accuracy standard, especially the tolerance of inside and outside diameter is very small. B. roller body size difference is less than or equal to 0.002 C.. The cylindrical roller has a convexity outer diameter to avoid stress concentration. D. rolling surface ultra precision treatment, high finish. 5、内部游隙 5. Internal clearance 游隙按振动机械要求生产,范围控制在很小范围内,一致性好。 The clearance is produced according to the requirements of vibration machinery, and the scope is controlled in a very small range, and the consistency is good. 6、使用效果 6. Effect of use 噪音低,温升小,稳定性好,使用寿命长,没有早期疲劳现象。 Low noise, small temperature rise, good stability, long service life, no early fatigue.
