Choosing a Slewing Ring Turntable

Choosing a slewing ring turntable is the best option if you want to enjoy your music at the best possible quality. There are a lot of advantages that you can get from choosing this kind of turntable. It also has a long life and is very reliable. Moreover, it comes with many features and applications that you can choose from.

Structure

Basically, a slewing ring is a pair of concentric rings that allow rotational motion between them. In most cases, the inner ring is affixed to a turning object via an adapter plate, while the outer ring lays flat against a motionless surface. Depending on the application, some slewing rings may incorporate an internal gear or an external gear. Slewing rings are commonly used in heavy duty machines, such as excavators, and are also used in port machinery, robotics, and wind power.

One of the best uses of the slewing ring is the fact that it can be used to sling heavy objects around. These are commonly used in construction machinery, such as excavators, cranes, and welding manipulators. They are also used in mining machinery, wind power, packaging machinery, and other industrial applications. They are also commonly found in marine machinery, such as dockside hoists and shipbuilding equipment.

The slewing ring can be classified into the single row ball slewing ring and the double row ball slewing ring. In general, the latter is used in vertical applications, such as cranes, and the former is used in rotary devices.

Rolling elements

Generally, a slewing ring turntable is comprised of two concentric rings. The outer ring is fixed to the mounting surface while the inner ring is rotated. The rotational speed of the inner ring is usually less than 10 rpm.

The rolling elements on a slewing ring turntable are usually in the form of a roller. They are kept in a heavily lubricated environment. They are separated by steel strip cages. These cages can be used to prevent contact between adjacent rolling elements. They also guide the rolling elements properly in the no-load area.

Rolling elements are generally made of 100Cr6, but they are also available in ceramic. Generally, these rolling elements are used in applications where high speeds and mass critical are required.

These rolling elements are usually inserted into a raceway. They are then induction hardened to a specific depth. The gap between the race and the roller is filled with lubricant. This provides a uniform spread of the load between the two bearings.

Lubrication

Unlike ball and roller bearings, slewing ring turntables can be a bit less complicated to maintain. The lubrication of such bearings is crucial to avoiding premature wear and tear. It is also important to know what type of lubricant to use. The best option is to consult your manufacturer for accurate recommendations.

Sliding slewing ring bearings are ideal for low to moderate loads and can be used in many applications, including industrial gearboxes and motors. They are corrosion resistant and have low moisture absorption. They do not require seals, making them easy to maintain.

The best way to maintain a slewing ring turntable is to monitor its performance. This can be achieved by checking the performance of its bearings and bolts periodically. The bolts should be replaced after seven years or fourteen thousand hours of operation. You should also check the condition of the tooth surface. This should be cleaned regularly and coated with a corresponding grease.

Applications

Various types of slewing rings are used in robotics, wind power, and mining. They also serve as components in packaging and drilling machinery. They are designed to transmit radial, axial, and moment loads.

Several slewing ring types are available, including the standard wire-race slewing ring and the slewing ring with sliding elements. The latter is made of plastic or hard-anodized aluminum, and provides a smooth surface for movement. It is ideal for applications that require light weights or intermittent rotation.

The slewing ring is a rotating part, which can be driven by a pinion or a gear. It is often integral to the machine component it supports, but it is also available as a separate gear. The slewing ring is generally screwed into place through evenly spaced mounting holes.

A slewing ring is designed to transmit radial, axial, moment, and thrust loads. The turning torque is calculated by considering factors such as the flatness of the supporting structure, the grease in the ring, and the seal type. The turning torque is also influenced by the applied load and the mounting orientation.
