What is the special performance NSK BELTOP 8 bearings? 2020 - 01 - NSK BELTOP 8 is designed specifically for 26 belt type stepless transmission ( The CVT transmission) Development of high reliability, low friction bearings, help to improve the reliability and efficiency of CVT. Belt type stepless transmission through the belt and pulley transmission engine power, with continuous stepless speed regulation ability. BELTOP 8 bearing performance is as follows: 1, configuration, structure and technical parameters ( FIG. 1) Figure 1 beltop 8 eight points in the configuration characteristics of low inside and outside the circle with special heat treatment ( 你的开支) , prolong service life; 'Through the use of special heat treatment ( UR EQTF) Ball, prolong life, improve card bite force majeure; Due to the use of plastic cage, longer life, friction, smaller and lighter weight; Low by setting the proper internal technical parameters of complex function; * compact, lightweight bearing ( Narrow offset channel) ； When introducing no worm outer ring ( High stiffness outer ring) To prevent the creep; Low by adding solid lubrication coating prevent bearing wear ( New features) ； Low on repairing circular channel block edges curb across shoulder defects ( New features) 。 2, features low high reliability ( FIG. 1) Figure 1 fatigue test results by optimizing the internal technical parameters and use of UE in the ring/HTF will prolong life. Another application EQTF on the ball, plastic cage instead of conventional cage, in the process of bearing operation can inhibit the deterioration of the surface roughness, longer service life. In addition, by taking advantage of the increase of outer ring stiffness peristalsis technology and adding solid lubricating coatings, can inhibit the bearing wear caused by CVT vibration increase. Low torque ( Figure 2, figure 3) Plastic cage can reduce the bearing lubricating oil mixing resistance produced by the rotation, reduce the friction. Figure 2 dynamic friction torque and the relationship between the oil amount figure 3 ties dynamic friction torque and rotational speed reducing size and weight by optimizing internal technical parameters, application of long life technology ( UR, THE and EQTF) , and by using offset channel and channel inhibition of climbing shoulder shoulder tip rounding bruises, can reduce the size and weight. 3, application BELTOP 8 products with long life, low torque and improve the creep resistance, small volume, lightweight, such as technology, not only applies to the belt type stepless transmission, also can be applied to all kinds of transmission, including automatic transmission and electric car/hybrid transmission. NSK BELTOP product contains 8 basic technology, based on the experience and achievement development project, is a kind of help applications in harsh environments using belt type stepless transmission with high reliability, low torque, small size and weight of the rolling bearing, currently used in many belt type CVT. Hk united bearing focus bearing industry informationization service nearly 20 years, with many excellent bearing enterprise grows together, also witnessed China's bearing production technology from low to high development process. We will adhere to continue, the steadfast work, don't, don't give up, for the benign development of Chinese bearing industry do render some. Hk united bearing network bearing engineers, 2019. 07. 26
