Plum-type Coupling

Product Description
Plum coupling is a common flexible coupling, also known as "chuck coupling", usually composed of two plum blossom sleeves, several star connecting bolts and other components. Its structural feature is that the center of the two plum blossom sleeves is on the same axis, and the sleeve and the sleeve are meshed with each other through star connecting bolts, so as to achieve torque transmission.

The advantages of plum-type couplings include:

  1. High torque capacity: Plum-type couplings have a high torque capacity, making them suitable for applications that require high torque transmission.

  2. Absorption of misalignment: Plum-type couplings can absorb misalignment between the drive and driven shafts, reducing stress on the system and extending the service life of the equipment.

  3. Dampening effect: Plum-type couplings have a dampening effect on the system, reducing vibration and noise levels.

  4. Easy installation: Plum-type couplings are easy to install and remove, making maintenance and replacement quick and convenient.

  5. Wide range of sizes and materials: Plum-type couplings are available in a wide range of sizes, materials, and designs to accommodate different applications and requirements.

  6. Versatility: Plum-type couplings can be used in a variety of applications, including conveyor systems, agricultural machinery, and industrial equipment.

Overall, plum-type couplings offer high torque capacity, absorption of misalignment, and a dampening effect on the system, making them a reliable and versatile solution for power transmission systems. They are available in a wide range of sizes and materials, and can be used in a variety of applications, ensuring a long service life and low operating costs.

It is widely used in automobiles, industrial machinery, mines, ships, electric power, medical equipment and other fields, providing an important guarantee for the efficient and reliable operation of these equipment.


Product Operation Guide

Coupling installation:


(1) Place the two plum sleeves of the coupling on the shaft connected to each other, and make sure that the hole center lines of the two torx sleeves coincide.


(2) Install star connecting plugs, according to different models of couplings, different numbers of star connecting bolts need to be installed, and the position and direction of each star connecting plug should be the same when installing.


(3) After installation, tighten the star connection bolt, not too tight or too loose.


Daily use and maintenance of couplings:


(1) During use, pay attention to avoid overload and overload, evenly distribute the load and reduce shock and vibration.


(2) Regular inspection and maintenance to ensure the good operation of the plum coupling. The inspection includes the appearance of the coupling, whether the coupling hole is deformed, whether the star connection plug has cracks and wear, etc.


(3) If a problem with the coupling is found and needs to be repaired or replaced in time, damaged products or unauthorized accessories must not be used.


In short, the operation guide of the plum coupling includes three aspects: preparation before installation, installation and daily use and maintenance of the coupling. When using, you need to pay attention to the following points: ensure that the installation location and environment are suitable, choose the appropriate model and specifications, pay attention to evenly distribute the load and reduce vibration, and regularly inspect and maintain. These measures ensure the normal operation of the product and extend the life of the Torx coupling.


FAQ

The following are frequently asked questions and answers to the Plum coupling:


1. How to prevent overload of plum coupling?


A: It is important to choose the appropriate model and specifications to ensure that the performance meets the requirements of use. At the same time, regular maintenance and inspection are carried out to avoid overload and overload.


2. How does the plum coupling prevent inconsistent speed?


A: Add a deceleration or speed increase device between the connecting shafts to ensure that the speed is consistent. During the installation process, pay attention to whether the plum blossom sleeve is deformed, and it needs to be installed on the same axis. 


3. How to overhaul and maintain the plum coupling?


A: It is necessary to clean and check whether the various parts of the coupling are intact, including the appearance of the coupling, whether the coupling hole is deformed, whether the star connection plug has cracks and wear, etc. If there is a problem, it needs to be repaired or replaced in time.
