The Institute has delivered numerous innovations and product improvements, generated a number of patents and other intellectual properties.
In 2010,Tongli devoloped his new patent"Elliptic Raceway Slewing Ring".After the slewing ring applied with elliptical raceway, its load capacity increases over 30%, and its service life doubled with the same diameter of the raceway and ball. And with the same load capacity, the diameter of the raceway can reduce 15%--30% (change by M/D/Fa), or the diameter of the ball can reduce 40%. As a result:
1.Under the same load capacity, it can save raw material over 20% and save procurement cost over 10%.
2.It has outstanding advantage in the occasion that the structure or the transport width is limited, such as automobile crane, pump truck, large-tonnage auto crane, and so on.
3.Especially, the single-row ball slewing ring with the same diameter which applied with elliptical raceway can substitute for the three-row roller slewing ring which diameter of the upper row roller is under28; while the double-row eight point contact slewing ring which applied with elliptical raceway can substitute for the three-row roller slewing ring which diameter of the upper row roller is under50.
It's widely used in XCMG, Fuwa, Hitachi ,Liugong, Zoomlion, Lishide,Carter, Jonyang,Rongan etc.
Advanced equipment,superb technics, perfect measuring,vigorous team sucessfully form our commitment to be a 'top-rank in China,well-known to World'brand.
