Belt wheel assembly considerations for pulley
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 belt wheel cover should be well and securely installed to ensure the loose exit of belt fault or pulley in operation. 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
Three and three inner hexagonal bolts are to be installed in place to ensure that the cones are uniformly axial, ensuring that the coaxial alignment of the belt and cone is good. 4, 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.
1, the last time before assembly must use gasoline cleaning, in order to make sure all the parts clean and dry, cooperate closely and no oil so as to ensure the matching surface, there is enough friction. 2 before assembly by turning the hex bolt, erection and 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.
