江苏HL type elastic pin coupling

The elastic pin coupling (GB5014-85) is suitable for various coaxial transmission systems. It uses the cross-sectional shear strength of nylon rods to transmit torque, the nominal torque is 160-160000N.M, and the working temperature is -20℃- 80°C.The structure is simple, with cushioning and damping performance, axis offset compensation ability, suitable for use in occasions where noise is not controlled.Allowable compensation is 0.15-0.25mm in radial direction and 0.5° in angular direction.The shaft hole types are cylindrical (Y), conical (Z) and short cylindrical (J).The shaft hole and keyway are processed according to the standard GB3852-83 "Coupling shaft column and keyway form and size".The semi-coupling is made of casting, iron HT20-cast steel ZG35Ⅱ, the shaft hole and keyway are made of drawing, and the pin is made of MC nylon b.Elastic pin couplings are generally elastic pin couplings and nylon rod pin couplings. The former is connected by several screws.

Characteristics of HL type elastic pin coupling:
1, 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 transmission shafts with strong impact and large vibration.
2, 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 pin with an elastic sleeve (rubber material) at one end , 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 nylon, which has the ability to compensate for 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, and is not suitable for workability. More demanding conditions.

3. 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;

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.
