Mechanical equipment installationSprocketsWhat are the assembly requirements for chains?
1. The parts should be thoroughly cleaned before assembly.
2. The center lines of the teeth of the driving sprocket and the driven sprocket should coincide, and the deviation should not exceed 2/1000 of the center distance between the two sprockets.
3. When the working side of the chain is taut, the sag f of the non-working side (see figure below) should meet the design specifications. When there are no specifications and the angle α between the chain and the horizontal line is less than 60°, it can be calculated as follows:SprocketsAdjust the center distance L by 1% to 4.5%.
