HL type-elastic pin couplingIt uses several pins made of non-metal elastic materials and is placed in the flange holes of the two halves of the coupling. The two halves of the coupling are connected by the pins. The coupling has a simple structure, easy to manufacture, and flexible in assembly and disassembly. The components are more convenient, and there is no need to move the two couplings.
The elastic parts are sheared during work and have poor workability. They are only suitable for medium-speed transmission shafts with very low requirements. They are not suitable for working conditions with high performance requirements. For example, the transmission shaft system of the lifting mechanism of hoisting machinery cannot be selected. It is not suitable for low-speed, heavy-duty transmission shaft systems with strong impact and large vibration, and should not be used for working conditions with large radial and angular deviations and transmission shaft systems with low installation accuracy. It is an obsolete product. .The pin in the German Lingsi elastic pin coupling shaft is in shear and squeezed state when working, and its strength condition is to calculate the shear strength of the elastic pin cross section and the squeeze between the pin and the pin hole wall strength.
HL type-elasticPin couplingcharacteristic:
1. The structure is simple, easy to manufacture, and it is convenient to install and disassemble the elastic element, without moving the two couplings;
2. The material of the elastic element (column pin) is generally nylon 6, which has the ability to compensate for the deviation of the two axes in a small amount. It is not suitable for low-speed, heavy-duty, and strong impact and vibration drive shaft systems.
3. The strength condition is to calculate the shear strength of the elastic pin cross section and the extrusion strength of the pin and the pin hole wall; the HL type elastic pin coupling uses a column with an elastic sleeve (rubber material) at one end. The pin is installed in the flange hole of the coupling halves to realize the coupling of the coupling halves.The material of the elastic element (column pin) is generally selected from nylon, which has the ability to compensate the deviation of the two axes in a small amount. The elastic part is sheared when working, and the workability is poor. It is only suitable for the medium-speed transmission shaft system with very low requirements. More demanding conditions.
