Description

Rigid couplings are known for their high rigidity and torsional rigidity, making them suitable for applications that require zero rotational clearance, even under heavy loads. They are designed to transmit torque without any deviation, ensuring efficient power transmission. However, it's important to note that any deviation in the system can lead to damage to the shaft, bearings, or couplings. Therefore, they are not recommended for high-speed environments where relative displacement between shafts can occur due to high temperatures.
That being said, rigid couplings can still be effective in servo system applications if the relative displacement is carefully controlled. In fact, small-sized rigid couplings made of aluminum alloy have gained popularity in motion control due to their lightweight, ultra-low inertia, and high sensitivity. These couplings offer maintenance-free operation and excellent resistance to oil and corrosion.
While there was skepticism in the past about using rigid couplings in servo drives, their high torque capacity, rigidity, and zero clearance performance have gained recognition. As a result, they are increasingly being utilized in the motion control field.

 

 

Effect

High Rigidity Coupling serves the purpose of linking the active shaft and driven shaft in various mechanisms, enabling them to rotate simultaneously and transmit torque. Additionally, certain couplings possess the added functionalities of enhancing the dynamic performance of the shaft system, reducing vibrations, and providing a buffering effect. It is essential to note that the generated content has been rearranged while maintaining the underlying information from the original text.

To minimize the impact of radial force, it is recommended to establish a direct connection between the motor spindle and the load, effectively eliminating any inertia. One approach is to utilize a coupling mechanism that helps reduce the initial force exerted on the motor during startup. By rearranging the provided information, we can form the following alternative text:
A coupling should be utilized to weaken the starting force when initiating the motor. This will allow for the elimination of inertia caused by radial force, promoting a direct connection between the motor spindle and the load. Such an arrangement will enhance operational efficiency and reduce strain during the startup process.

Power transmission refers to the process of transferring power and torque from one component or system to another. It plays a crucial role in improving the overall performance of the transmission system. By effectively transmitting power and torque, the efficiency and reliability of the system are enhanced. This ensures smooth operation and optimal functioning of the machinery or equipment involved. Power transmission is essential in various industries and applications, such as automotive, manufacturing, and energy sectors. It involves the utilization of different mechanisms and technologies to transfer power, including gears, belts, chains, and shafts. These components work together to transmit power efficiently and effectively, resulting in enhanced working performance of the transmission system.

Vibration reduction and buffering effects can vary to different degrees. It is important to understand the various levels of effectiveness in order to choose the best solution for your needs. When it comes to vibration reduction, different materials and technologies are available that can provide varying degrees of dampening. Some materials are highly effective at reducing vibrations, while others may only offer minimal damping. Similarly, buffering effects can also differ depending on the specific solution employed. Buffering materials and techniques can range from soft, cushion-like materials to more rigid structures that absorb and dissipate energy. The extent of buffering provided by these solutions can vary, so it is crucial to consider the specific requirements of your application before selecting the appropriate option. Ultimately, understanding the different degrees of vibration reduction and buffering effects will help you make an informed decision that suits your specific needs.

7. Change the transmission direction

Concentricity correction, available in varying degrees of axial, radial, and angular compensation performance, is a crucial aspect of precision engineering. This correction process aims to optimize the alignment and concentricity between different components, ensuring their flawless functioning. By carefully adjusting the axial, radial, and angular parameters, manufacturers can achieve accurate alignments and reduce any deviations that might arise during the manufacturing process. This correction procedure plays a vital role in enhancing product quality and performance, particularly in industries where precision is of utmost importance.

 

Coupling installation method

1. Bolt direct fixing type

The most conventional and low-cost method of connection involves using screws to directly attach the front end to the shaft. However, there is a risk of damaging the shaft or making it difficult to disassemble due to this direct contact. Therefore, it is crucial to pay attention and take necessary precautions when using this method.

2. Clamping type

The countersunk bolt utilizes its tightening force to effectively compress the slit, creating a secure grip around the center of the shaft. This design allows for easy and hassle-free installation and disassembly processes without causing any harm or damage to the shaft.

3. Separation type

The ease of fixing and disassembling the shaft sleeve without the need to move the device is one of its key advantages. Furthermore, this process does not result in any damage to the axis, making it even more convenient. The shaft sleeve's complete separation feature allows for effortless repairs and disassembly, providing efficient maintenance without any adverse effects on the axis.

4. Semi detached type

The shaft sleeve's connection method involves using a clamping type at one end and a separate type at the other end. To install, begin by securing one end of the shaft into the clamping type sleeve. Then, proceed to insert the other end into the separate type sleeve. This installation process is straightforward and uncomplicated.

5. Keyway type

The direct bolt fixation type is the most conventional method of fixation that is perfect for transmissions requiring higher torque to prevent any axial movement. It is usually fixed directly with bolts and used in combination with the clamping type. This method is highly suitable for ensuring a secure and safe transmission of power.

The connection method of the expansion sleeve type relies on the conical bevel amplification effect, providing a dependable and consistent connection. This type of connection is particularly suitable for high torque transmission and is highly recommended for machine tool spindles. By utilizing the expansion sleeve type, a secure and stable connection can be achieved, making it an ideal choice for various applications.
