The LZ (ZL) elastic column pin toothed coupling is a column pin made of several non-metallic elastic materials, which is placed in the mating hole between the two halves of the coupling and the inner surface of the outer ring. The torque is transmitted through the column pin to achieve the connection of the two halves of the coupling
The LZ (ZL) elastic column pin tooth coupling has a simple structure and is easy to manufacture. It is convenient to install, disassemble, and replace elastic components without moving the two halves of the coupling. And it does not require lubrication, is easy to maintain, and has a certain elasticity and vibration absorption performance, but the temperature used should not exceed 70 ℃. The allowable relative displacement of the two connected shafts. For couplings without intermediate shafts, the allowable radial displacement △ y is 0.3-1.5mm, the allowable axial displacement △ x is 1.5-5mm, and the allowable angular displacement △ y is greater than 30 '. For couplings with intermediate shafts, the allowable radial displacement △ y is 0.15-0.75mm, the allowable axial displacement △ x is 1-20mm, and the allowable angular displacement △ a is 0 ° 30' -2 ° 30
Features:
(1) The transmission torque is large, and when the same torque is applied, the rotation diameter is mostly smaller than that of the gear coupling, with small volume and light weight, which can partially replace the gear coupling.
Compared with gear couplings, they have a simple structure, fewer components, convenient manufacturing, and do not require gear processing machines. There are two types of couplings: one is directly connected to the main and driven shafts using a single elastic pin toothed coupling, and the other is connected to the main and driven shafts using two couplings with intermediate shafts. Easy to manufacture, easy to install, and lightweight(3) Easy to maintain, with a longer lifespan. The nylon pin can be replaced by removing the gear plate. Nylon column pins are self lubricating materials that do not require lubrication, which not only saves lubricating oil but also purifies the working environment(4) Poor damping energy and high noise. It has the ability to compensate for the relative deviation between two axes and is suitable for medium and high power transmission. It is not suitable for working parts that have specific requirements for vibration reduction and require strict control of noiseThe LZ (ZL) elastic pin tooth coupling has good compensation performance for axial, radial, and angular axis deviation, good vibration reduction performance, simple structure, smooth operation, no noise, no need for lubrication, convenient maintenance, simple assembly and disassembly, good processability, low cost, and can be derived into various structural forms. It has good universality, wide applicability, and is easy to promote
