Single-row cross roller slewing ring (11 series)-internal gear type

Structural features, functions, scope of application

The slewing ring is a new type of mechanical parts. It is composed of inner and outer rings, rolling elements, etc. The slewing ring is a large bearing that can accept generalized loads, and can accept large axial and radial loads and overturning moments together. The depth of the hardened layer of the single-row interspersed roller slewing ring raceway The depth of the hardened layer of the raceway is currently non-destructively tested. It is mainly ensured by technology and equipment. The necessary depth of the hardened layer is such that the slewing ring does not fall off. To ensure. What kind of impact will the insufficient depth have on the bearing capacity of the slewing ring? The additional static capacity CO is proportional to the depth of the hardened layer H0.908. If the depth of the hardened layer required to be 4mm is only quenched to 2.5mm, then the CO will be reduced from 1 to 0.65. The resulting slewing bearing failure mode is rolling If the road falls off, even if the welding repair method is adopted, it is in vain.

The slewing bearing is a representative rolling bearing with a wide range of uses. It is used for high-speed and even extremely high-speed operation and is very durable. This type of bearing has little conflict, high limit speed, simple structure, low cost, and easy to achieve high production accuracy. The slewing ring bearing also has a certain aligning ability. When it is skewed by 10 degrees relative to the housing hole, it still works normally, but it has a certain impact on the life of the bearing. Slewing ring bearing cages are mostly stamped steel plate corrugated cages, and large bearings are mostly car-made metal solid cages.
