- Flexible pin coupling: (1) HL type - flexible pin coupling has been listed as a national standard GB5014-85, applicable to a variety of mechanical coupling two coaxial drive shaft, usually used to move the frequent low-speed movement. Operating temperature -20 ~ +80 ℃; to pass nominal torque of 40 ~ 20000N.m. ② flexible pin coupling with a larger structure is simple, reasonable, easy maintenance, both sides symmetrical interchangeable, long life, allow greater axial movement, cushioning, shock absorption, wear performance. ③ flexible pin coupling is the use of certain non-metallic elastic material made of studs placed in the coupling halves flange hole, through the studs to achieve coupling halves coupled, the simple structure of the coupling, easy to manufacture, assembly and disassembly to replace the elastic element, do not move the two coupling halves. Elastic element (Pin) of the material is generally used in nylon, traces compensation capacity of two-axis offset, shear elastic member work by the working poor reliability, and applies only to the requirements of low-speed drive shafts, NA in working conditions requiring high reliability. The HL - Elastic pin coupling base ④ this parameter and the main dimensions of shaft hole type the cylindrical (Y) (Z) and short cylindrical conical (J). Shaft bore and keyway according to the national standard GB3852-83 the coupling shaft pillar and keyway form and size, "the provisions of processing. Coupling half using precision casting, cast iron HT20-40, ZG35 Ⅱ cast steel shaft bore and keyway drawn shaped pin made of MC nylon b. 2.HLL - flexible pin coupling with brake wheel: HLL - brake wheel flexible pin coupling The coupling has been included as the national standard GB5014-85, two same applies to a variety of mechanical couplings The axis of the drive shaft, usually used to move frequently high and low speed movement. Flexible pin coupling product description: consists of two identical halves couplings and nylon dowel pin, baffle and bolts. Pin into the pin holes on the two coupling halves flange which is loaded in the direction of the coupling half-holes is alternating. Side of the coupling halves fixed bezel. Operating temperature -20 ~ +80 ℃; to pass nominal torque of 40 ~ 20000N.m. Main features: flexible pin coupling has a simple structure, reasonable, easy maintenance, both sides symmetrical interchangeable, long life, allowing greater axial movement, cushioning, shock absorption, wear performance. Brake wheel and coupling halves split structure, brake wheel and coupling halves bolted to also replace the bezel. Steel brake wheel cylindrical surface hardening treatment. Flexible pin coupling for occasions: applies only to the requirements of low-speed drive shafts, The discomfort for work requiring high reliability condition.
