The main reason why the sprocket chain drive generates dynamic load during work is

(1) The chain speed and the driven sprocket angular speed change periodically, resulting in additional dynamic load.The greater the acceleration of the chain, the greater the dynamic load will be.The acceleration of the chain is visible, the higher the speed of the sprocket, the larger the chain pitch, and the less the number of sprocket teeth, the dynamic load will increase. (2) The speed of the chain in the vertical direction...

The main failure mode of roller chain drive

The main failure modes of chain drive are as follows: (1) Fatigue failure of chain plate Under the repeated action of the tension of the loose side and the tension of the tight side, the chain plate will suffer fatigue damage after a certain number of cycles.Under normal lubrication conditions, fatigue strength is the main factor limiting the load-carrying capacity of a chain drive. (2) Roller sleeve…

Heat treatment of gear sprocket made of 45 gauge steel

According to the requirements of the sprocket gear: if the impact force is small, surface carburizing, nitriding and other technologies can be carried out!In this way, the surface hardness is high, the matrix hardness is low, the wear resistance is good, and it is not easy to break.If the impact load is large, it is due to the quenching and tempering treatment, that is, high temperature tempering. 45#…

Analysis of Design Calculation of Roller Chain Drive

1. Failure form of chain drive 1) Fatigue damage of chain When the chain is working, the chains on both sides of the sprocket are tensioned and relaxed.The chain continuously moves from the loose edge to the tight edge, so all its components work under the action of variable stress. After a certain number of cycles, the chain plate will have fatigue fracture…

Analysis of the Causes of the Chain Stuck or Broken Chain of the Sprocket Chain in the Scraper Conveyor

Failure: One of the main functions of the scraper conveyor in the fully mechanized mining face is to transport the coal blocks cut by the shearer, which is realized by the chain installed on the scraper conveyor.The chain itself is an elastic body, and the amount of coal cut by the shearer is uncertain, resulting in inconsistent weight of coal blocks carried by the scraper conveyor chain.long…

Simple calculation method of analytical sprocket

1. The number of teeth Z of the sprocket is calculated according to the transmission ratio ι: ι=n2/n2=Z1/Z1 In the formula: n2: the speed of the small sprocket n1: the speed of the large sprocket Z2: the number of teeth of the small sprocket ZXNUMX: The number of teeth of the large sprocket is two, the diameter of the index circle of the sprocket...
