Simplify designs with slewing bearings.

Slewing bearing is used to connect the top and bottom of the machine together, also used to support the weight of the upper part and the machine work when the load, and make relative to the top of the lower rotating machinery.  This article mainly introduces the simplify designs with slewing bearings. 

Here are the main points of the article:

• Simplify designs with slewing bearings

• Simplify configurations with slewing bearings configuration

1.Simplify designs with slewing bearings

Slewing ring bearings can be used to simplify a drive system by incorporating gear teeth on the inner or outer race. Slewing ring bearings also save space, making it practical to use one bearing instead of two, thereby reducing the height required for an application. 

The latest white paper describes common tooth forms, angles, and hardness; explains the Lewis formula for tooth size and form selection; includes tables that designers can use to match gear details to their applications; and describes how to install a slewing ring bearing. 

2. Simplify configurations with slewing bearings configuration

In the machine tool industry, the standard of the structure of the slewing bearings with high precision level and at the same time exerted load to eliminate clearance, to reduce the vibration. Slewing bearings itself structure compact design, small cross section size, and the diameter range can be as small as 50 mm (this type of slewing bearings of steel ball size than traditionally used heavy series rotary bearing steel ball size small). This causes the designer started to traditional slewing bearings configuration to reconsider. 

In the moment of slewing bearings design choice depends on the load, stiffness, rotational speed, such as the size and rotation flexibility requirement, and considering the various aspects of practical application, the user and the slewing bearings manufacturer to design goal and slewing bearings applicability were discussed, help in lower cost and guarantee trouble-free working under the premise of the performance of the system to reach optimization. 

Commonly used to bear radial, axial and torque load of the derrick bearing, its installation configuration using two sets of ball or roller slewing bearing along the axial interval set form of this configuration is by two sets of slewing bearings on the shaft is set to obtain a higher torque load capacity over a long distance. 

However, for such a configuration, due to the space limitations and installation complexity, it is difficult to adapt to new applications, and this is the advantage of rotary bearing. Using a set of slewing bearings instead of two sets of slewing bearings not only can reduce the height of plant, also can simplify the structure of components, therefore, slewing bearings is particularly suited to the new type of industrial automation control device. 

Good design choice or a four-point contact ball slewing bearings, contact Angle formed at the intersection of a larger effective pitch diameter to offset the effect of negative moment. In addition, the use of large size of a single set of slewing bearings, can make the ball through contact with the channel slewing bearings in the center of the hole. This simplifies the overall design, improves the shape and protects the parts.
