Product Details

HL type elastic pin coupling is a pin made of several non-metal elastic materials, which is placed in the flange hole of the two halves of the coupling, and the two halves of the coupling are connected by the pin. The coupling has a simple structure , It is easy to manufacture, it is more convenient to assemble and disassemble the elastic element, without moving the two couplings.

The elastic parts are sheared during work, and the workability is extremely poor. It is only suitable for medium-speed transmission shafts with very low requirements. It is not suitable for working conditions with high performance requirements. For example, the transmission shaft system of the lifting mechanism of hoisting machinery cannot It is not suitable for low-speed, heavy-duty transmission shaft systems with strong impact and large vibration. It should not be used for transmission shaft systems with large radial and angular deviations and low installation accuracy. Eliminate varieties.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 on the cross section of the elastic pin and the squeeze between the pin and the pin hole wall strength.

Characteristics of HL type elastic pin coupling:

1. The structure is simple, easy to manufacture, and it is convenient to install and disassemble the elastic element, and there is no need to move the two couplings;

2. The material of the elastic element (column pin) is generally nylon 6, which has the ability to compensate the deviation of the two axes in a small amount. It is not suitable for low-speed, heavy-duty and transmission shafts with strong impact and large vibration.

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 slightly compensate for the offset of the two axes. The elastic part is sheared when working, and the workability is extremely poor. It is only suitable for the medium-speed transmission shaft system with very low requirements. Working conditions with high workability requirements.
