To promote energy-saving and emission-reduction technologies of belt drives

a new high efficient and safety belt drives system technology is developed.The development of domestic energy-saving emission reduction technology of the belt drives of pumping unit is discussed.The high efficient and secure belt drive system composition is discussed

and the two key components-energy-saving and safety ball-type coupling and high efficient belt drive are introduced.The working process

the structures and the characteristics of the ball-type coupling have been introduced in detail.The recommend high efficient belt drive is also simply introduced.The main process of design of the new high efficient and safety belt drive system is introduced

and suggests using the new belt drive system in various fields.
