Industrial sprocket

Industrial sprocketIn the process of processing, attention should be paid to various factors such as the size, structure, heat treatment requirements of the sprocket, the final finishing method of the tooth surface, and the batch of products.

  For the chain sprocket with large size and medium hole, the tooth part should be machined on the gear machine; the shaft sprocket integrated with the shaft, the bar is cut, the shaft part is turned, and then the tooth part is machined on the gear machine;Large sprocket, Casting or flame-cutting thick steel plate into blanks, or welding into sprocket blanks, and then processing the teeth.

Industrial sprocketInstallation Precautions:
(1) Install the crankshaft chain lun.
(2) Install the timing chain damping plate on the cylinder block.
(3) Align the timing mark on the crankshaft chain lun with the timing mark on the bottom of the timing damper plate.
(4) Hang down the timing chain, fix the camshaft sprocket, and install the timing chain on the crankshaft gear.
(5) Align the center line of the positioning hole on the camshaft chain lun with the timing mark on the top of the timing chain damping plate.
(6) Align the positioning pin on the camshaft with the positioning hole on the camshaft chain lun.Install the chain lun on the camshaft, and the bolt tightening torque is 100N·m.
(7) Lubricate the timing chain and chain lun with engine oil.
(8) Rotate the crankshaft twice to check whether the engine timing marks are aligned.If the timing marks are not aligned, follow the above operation points and perform the operation again
