How to Select a Locking Assembly

A locking assembly is a device that is used to connect two shafts and hubs in order to produce a frictional connection. Locking assemblies are used in various applications, including pumps, brake disc mountings, machine tools, and spiral wheels. They are designed to handle large forces without backlash.

Locking assemblies are manufactured to high standards and can be found in several designs. The basic design consists of a single or double taper thrust ring. This design is better suited for applications that require bending movements, such as in pulley systems.

Keyless lock assemblies are used in a variety of applications, including hydraulic clutches, flange couplings, and speed reducers. These devices are keyless and offer easy installation and adjustment. They also eliminate backlash, eliminating costly machining and downtime.

When selecting a locking assembly, it is important to consider the size of the shaft and the material it is made of. Having the right dimensions will ensure the best performance. For instance, if the shaft is too small, the locking device might not be able to transmit the required torque. In addition, the hub may be too large, which could result in failure.

It is advisable to talk to your manufacturer’s engineering team about potential problems in early stages of designing. This will help you avoid costly mistakes in the long run. Moreover, you’ll learn more about their products and how to avoid weak points.

The quality of the components you use in your locking assembly is essential to its precision. If the material is not of high quality, the screws will be overtightened and the hub may suffer deformation. Also, you should ensure that the axial and radial loads are properly balanced. High-quality materials like stainless steel can help protect the shaft and other valuable parts of your machine.

It’s also recommended that you check the torque capacity of your slit adaptor sleeves. Rated torque capacities are based on the wall thickness of the adaptor. For instance, if you measured the diameter of the shaft, a slit adaptor sleeve should not exceed 12.5% of that diameter.

In order to minimize the costs of the shaft, it is advisable to consider using locking devices with smaller bearings. This is especially beneficial if the shaft is in a high-temperature application. Additionally, reducing the bearing size will lower the inertia of the shaft. However, this can reduce the overall diameter of the locking assembly.

There are many other factors that must be considered when choosing a locking device. For example, a locking device must be able to withstand high stresses and humidity. The locking device must also balance the load and temperature. Another consideration is the amount of frequent component removal and replacement.

A locking assembly combines a shaft and hub with a high clearance. With this combination, the force and stress are evenly distributed over the entire 360-degree contact. The high pressure keeps out contaminants and prevents wear. As a result, the locking assembly is superior to external clamping connections.
