The post External-toothed slewing ring appeared first on ZZ.

]]> An external-toothed slewing ring is a specialized type of bearing engineered for heavy-duty rotational applications. It consists of a large circular ring with external gear teeth machined onto its circumference. These gear teeth enable controlled rotation when engaged with a pinion or other driving mechanism.

The design typically comprises three main components:

Outer Ring: Constructed from high-strength steel or alloy, the outer ring provides robust support for heavy loads and ensures durability.

Gear Teeth: Machined onto the outer diameter, the gear teeth facilitate controlled rotation and precise positioning when coupled with a pinion or gear mechanism.

Inner Ring: Supporting axial and radial loads, the inner ring ensures stability and smooth rotation. It often integrates mounting holes or other features for easy installation.

Applications:

External-toothed slewing rings are indispensable in various industries and machinery, including:

Construction Machinery: Cranes, excavators, and drilling rigs rely on slewing rings for heavy load-bearing and rotational movement.

Renewable Energy: Wind turbines and solar trackers utilize slewing rings to orient components for optimal energy capture.

Material Handling: Conveyor systems, turntables, and rotary tables employ slewing rings for efficient material distribution.

Aerospace and Defense: Radar systems, missile launchers, and satellite tracking systems benefit from the precision and reliability of slewing rings.

  • Gear Design:

The distinctive feature of an external-tooth slewing bearing is the presence of gears on its outer race. These gears are typically driven by mechanisms such as racks, motors, or other power sources, providing the bearing with self-driving capability.
Inner Diameter, Outer Diameter, and Width:

Similar to other bearings, the inner diameter, outer diameter, and width are basic geometric parameters of the external-tooth slewing bearing. These parameters determine the bearing’s dimensions and adaptability.

  • Load-Carrying Capacity:

External-tooth slewing bearings are designed to withstand substantial radial and axial loads, making them particularly useful in applications requiring support for large structures or rotational movements of equipment.
Gear Module and Pressure Angle:

The gear module is a measure of gear size, while the pressure angle describes the tooth profile. These parameters influence the transmission efficiency and precision of the bearing.

The applied stresses of the rolling elements on the raceways are calculated according to the Hertz laws and the modern criteria of plasticity. ZZ carries out localized hardening treatments which makes it possible to satisfy these criteria just as well in terms of surface pressure as well as subsurface fatigue.

For the slewing ring manufacture, ZZ selects the best material specifications to suit most foreseen usages.These materials are manufactured by approved steel works.Inspections are carried out at each significant step of manufacturing what makes it possible to warrant the quality of the products. Most of the time, we select high-grade Carbon steels which permit us to meet all operating requirements.Core hardening and tempering are carried out when the applied stresses dictate these processes.

There are two types of curves in the graph. One is the static load curve, which represents the maximum load that the slewing ring can bear when it remains stationary. The other is the limit load curve of slewing bearing bolts, which is determined when the clamping length of the bolt is 5 times the nominal diameter of the bolt, and the pre-tightening force is 70% of the yield limit of the bolt material.

]]> slewing bearing selection

Selection of structure type: There are four types of commonly used slewing bearings: single-row ball type, cross-roller type, double-row ball type, and three-row column type.
According to our experience and calculations, we have the following conclusions:

Slewing bearing installation
When Do ＜ 1800, single volleyball is the preferred type;
When Do＞1800, three-row column slewing ring is preferred.
If the slewing ring with the same external dimensions, the load capacity of the single-row ball type is higher than that of the cross roller type and the double-row reducing type, the Q series single-row ball type slewing ring has a more compact size, a lighter weight, and a better cost performance. The preferred series of single volleyball style. slewing bearing selection

Note:

  • n1 is No. of lube holes, the user can specify the lube hole position.
  • n-φ can be changed to threading holes, hole diameter M, thread depth 2M.
  • There are standard products in the catalog, and the inner and outer diameters are random tolerances. If there is a locating requirement for slewing bearing, please indicate the site and tolerance.
  • It is standard type of our products, if you need more please contact with engineer.

Note:

  • n1 is No. of lube holes, the user can specify the lube hole position.
  • n-φ can be changed to threading holes, hole diameter M, thread depth 2M.
  • There are standard products in the catalog, and the inner and outer diameters are random tolerances. If there is a locating requirement for slewing bearing, please indicate the site and tolerance.
  • It is standard type of our products, if you need more please contact with engineer.
