Rokee® Customized ZL Elastic Pin Coupling for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
ZL elastic pin coupling is a device that uses several non-metallic materials to make column pins, which are placed in the mating holes between the two halves of the coupling and the inner surface of the outer ring, and transmit torque through the column pins to connect the two halves of the coupling.
Main features of ZL elastic pin coupling
High transmission torque: At the same torque, its rotational diameter is mostly smaller than that of a gear coupling, so it has a small volume and light weight, and can partially replace a gear coupling.
Simple structure: Compared with gear couplings, it has fewer components, is easier to manufacture, and does not require gear machining machines.
Easy maintenance: Its installation, disassembly, and replacement of elastic components are relatively convenient, without the need to move the two halves of the coupling. Meanwhile, the nylon column pin is made of self-lubricating material and does not require lubrication, which not only saves lubricating oil but also purifies the working environment. When repairing, remove the baffle to replace the nylon pillar pin.
Compensation capability: It has a certain ability to compensate for shaft offset and general shock absorption performance.
ZL elastic pin coupling is suitable for coaxial transmission shaft systems, utilizing the longitudinal shear strength of nylon rods to transmit torque. Its working temperature range is -20~70 ° C, which can partially replace toothed couplings. In addition, it also has the performance of compensating for the relative offset of the two axes, which is suitable for medium and high power transmission. However, it should be noted that it is not suitable for work areas with specific requirements for vibration reduction and strict noise control.
When choosing ZL elastic pin coupling, the appropriate type should be determined according to the working conditions, and then the specific size of the coupling should be selected according to the torque and speed of the shaft. The main technical parameters include the main dimension D, allowable shaft hole, shaft hole length Y, nominal torque Tn, allowable speed n, and moment of inertia I. Among them, there are multiple specifications of allowable shaft holes to choose from, such as 12, 14, 16, 18, etc., to meet the needs of different shaft diameters.
The assembly steps of ZL elastic pin coupling are relatively simple, mainly including the following steps:
Install the outer ring onto the half coupling and secure it onto the flange of the half coupling using a suitable baffle.
Secure the outer ring and half coupling with screws.
Fill the nylon rod into the hole between the outer ring and the half coupling.
Install the other half coupling into the outer ring and continue to insert the nylon rod into the hole of the outer ring and half coupling.
Finally, use screws to secure the other baffle to the outer ring of the coupling.
precautions
When selecting and purchasing, attention should be paid to ensuring that the aperture range of the selected coupling matches the diameter of the shaft, and that the specified allowable torque is greater than or equal to the working torque.
During use, the wear of the coupling should be checked regularly, and severely worn components should be replaced in a timely manner.
Couplings should be avoided from being used under overload or harsh working conditions to extend their service life.
ZL elastic pin coupling has the characteristics of simple structure, easy manufacturing, large torque transmission, convenient maintenance, and certain compensation ability. When selecting and using, attention should be paid to following relevant technical parameters and precautions to ensure its normal operation and extend its service life.
