Gasoline must be used for the last cleaning of the belt pulley assembly to ensure that the parts are clean and dry, so as to ensure that the mating surface is tightly matched and free of oil pollution and sufficient friction.
Inside hexagonal bolts for assembly should also be washed and dried with gasoline before assembly. Lubricating oil or grease should not be applied in bolts or holes to ensure that the bolts have sufficient friction self-locking ability after tightening.
When the three inner hexagonal bolts are about to be installed in place, they need to be tightened in turn to ensure that the taper sleeve receives uniform axial force and that the pulley and the taper sleeve are positioned in good coaxiality.
Check and measure the length of the inner hexagonal bolt before installation to ensure that the assembly bolt can hold the bottom of the blind hole of the cone sleeve after tightening, so as to ensure that the cone surface fits tightly and that the bolt is pushed backward by the bottom of the blind hole, thus producing the same anti-loosening effect as the double nut principle.
Inspect and adjust the relative position of the main and driven pulleys after the pulleys are fastened to ensure that the two pulleys are in the same plane and the belt tension is moderate.
The pulley cover shall be in good condition and firmly installed to ensure that the breakage of the belt or the loosening of the pulley during operation will result in a major safety accident.
The taper sleeve belongs to the fragile parts. Belt Pulley Assembly After a long period of operation, the inner hole and chain groove may be damaged. Before each assembly, it should be inspected and the spare parts should be replaced in time if defects are found.
