Slewing Bearing With Internal Gear with gear on the internal ring. Gear hardening treatment or not is based on the working conditions. Compared with slewing bearing with external gear, the internal gear will has longer service life when worked in the same environment due to the gear is in the inner ring, as it can make the gear has good dust prevention and the grease oil can be kept for a longer time and more important the internal teeth have lower transmission contact stress and less wear. However, it is inconvenient for installation and fault diagnosis check after some time using due to the size limitation and compact interior space.
Features and Benefits of Slewing Bearing With Internal Gear
One of the main quality issues we encountered in our aftermarket work a few years ago was raceway noise.
Why is there a raceway noise? We think that the main reason is that the hardness of the raceway is not enough or the quenching depth of the raceway is not enough.After a long period of wear between the steel ball and the raceway, the raceway will be worn out.
Starting from a small area, if the problem become serious, a very loud noise will be emitted. In order to solve this problem, we started from the raceway grinding equipment and the raceway grinding process.
After continuous exploration by engineers and front-line workers, we have successfully mastered and improved the raceway grinding production process, ensuring that there was no noise problems again from that time.
slewing bearing or slewing ring is a rotational rolling-element bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. Slewing bearings with internal gear are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base. We produce different slewing bearings with internal gear to meet your your various needs of the slewing ring bearing with internal gears.
