Three-row drive chains from the manufacturer

Commercially available three–row drive chains are made from individual product components. They are used to transfer torque from the shaft of a power unit to the gearbox shaft of a device performing mechanical work. Official website https://privod-tsepi.ru/privodnyie-czepi/tryoxryadnyie-czepi / the manufacturer represents mass-produced, three-row models, each link of which has the following design scheme:

  • Metal side plates.
  • Connecting rollers.
  • A system of bushings and movable rollers.

Such links are fixed in three rows and typed along the desired chain length. The outer and inner plates of each adjacent row are arranged coaxially, which ensures an even distribution of the external load between them. The free rotation of the rollers reduces the friction that occurs when rotating with the help of a gear.

Classification and main types

Three-row drive chains are manufactured according to the established domestic GOST standards. They have the abbreviation of the designation, which is generally accepted for Russian and foreign engineering and technical reference books.:

  • "3" is a three–row structure. 
  • PR – drive roller chain.
  • The digital value is the chain pitch (mm).
  • The second group of figures is the magnitude of the destructive structural load (kN).

Additionally, in the description for each model, the manufacturer indicates the diameters of the rollers and rollers, the width between the plates, the length of the roller and roller, the height and thickness of the plates.

Scope of application

The design of the three-row drive chains is designed to perform mechanical work associated with high loads. They can maintain their working capacity for a short time even in the event of a rupture or damage to one in-line link. A significant margin of safety allows them to be used for maintenance:

  • Stationary lifting mechanisms.
  • Aggregates of excavators and loaders.
  • Conveyor systems.
