What are the precautions for pulley assembly
The belt wheel cover should be well and securely installed to ensure that the belt break or loose exit of the pulley is a major safety hazard. 7, taper sleeve belong to wearing parts, after long time operation, inner hole and the chain slot may be damaged, should check before every assembly, finding defects should be timely replacement of spare parts.
Before the installation within the check assembly measured in hex bolt length, so as to guarantee the assembly bolts can resist taper sleeve after blind hole bottom, cooperate closely to ensure the cone, and ensure the bolt by blind holes on the bottom of the reverse thrust, produces the principle of double nut locking function. After the pulley check and adjust the position of the main and moving pulley, ensure that the two wheels are in the same plane and the belt is tight.
The three inner hexagonal bolts are to be installed in place to ensure that the cones are uniformly axial and ensure that the coaxial alignment of the belt and cone is good.
Assembly with hex bolt assembly before application of gasoline cleaning and dry, not in a bolt or screw hole lubricating oil or grease, coating to ensure that the bolt fastening has enough friction self-locking ability.
Last clean before assembly must use gasoline, to ensure that all parts clean and dry, cooperate closely and no oil so as to ensure the matching surface, there is enough friction
