To Make The Transmission Of The Chain Play The Best Role Must Master The Relevant Knowledge

The role of the chain is simply the role of a transmission. How to make the chain transfer action decorative chain use to the best? Let's take a look at the proper use of chain drive.

First of all, we must ensure that the rotation plane of the two sprockets should be in the same vertical plane of the safety chain, otherwise it is easy to make the chain produce abnormal wear or the chain is easy to fall off. Secondly, the center connection of the two sprockets is best horizontal, and try to avoid vertical transmission, so as to avoid poor engagement or disengagement with the lower sprockets.

The tension force of the chain drive does not determine the working ability of the chain, the knowledge determines the size of the verticality, and the most common method of tension is to move the sprocket to increase the central moment of the two wheels. If the center distance is not adjustable, the tension wheel can also be used to tighten, and the tension wheel should be installed near the loose edge of the drive sprocket. In addition, it can also be tensioned with a pressure plate or a pallet, especially for chain transmission with a large center distance, and it is more reasonable to control the sag with a pallet.

The lubrication of the chain drive is also very important, and appropriate lubrication can reduce the wear of the chain and extend its service life. How do you lubricate the chain? In general, there are several methods. Manually apply regularly with an oil can or brush; Oil bath lubrication or splash lubrication, using a sealed transmission box, the former chain and sprocket part immersed in the oil, the latter using a larger diameter of the oil tray splash oil; Oil pump pressure injection oil lubrication, oil pump through the pipeline to the chain continuous oil supply, circulation oil can play the role of lubrication and cooling. Kinematic viscosity of lubricating oil used in chain drive is about 20 ~ 40mm2/s at operating temperature. Only where the speed is very slow and the oil cannot be supplied, can grease be used instead.
