CHAIN TRANSMISSION-RELIABLE AND EFFICIENT

Chains used in mechanical engineering by the nature of their work are divided into three main groups: drive, traction and cargo. Drive chains are the most common. They transmit movement from the energy source to the receiving organ of the machine. The object of the invention is to ensure the transmission of motion in three-row chain gears when transmitting high power and to ensure the uniformity of movement of the driven sprockets. This task is solved by improving the design of the chain transmission by installing sprockets with a phase shift and performing the chains of all three rows separately. The essence of the design is that the chain transmission is made in three rows, including three parallel mutually paired (connected rigidly) with a phase shift of the angle t / 3 (where t is the step between the teeth of the sprockets or the chain step), three leading and three driven sprockets, and all three chains are separated from each other and independently engage with the corresponding sprockets.
