A reciprocating impact part non-concentric protruding shaft fixed bearing method, comprising the following steps:
- 1) arranging eccentric shaft sections and power shaft sections, arranging eccentric shaft section bearings on the eccentric shaft sections, and arranging power shaft section bearings on the power shaft sections;
- 2) arranging power shaft section bearing retaining rings and eccentric shaft section bearing retaining rings, such that the power shaft section bearing retaining rings and the eccentric shaft section bearing retaining rings respectively block the power shaft section bearings and the eccentric shaft section bearings, or the power shaft section bearing retaining rings and the eccentric shaft section bearing retaining rings are made into integrated non-concentric connected retaining sleeves, the external diameters of the power shaft section bearing retaining rings of the non-concentric connected retaining sleeves are smaller than the internal diameters of power shaft section bearing outer supporting rings, the external diameters of the eccentric shaft section bearing retaining rings are smaller than the internal diameters of eccentric shaft section bearing outer supporting rings, the power shaft section bearing retaining rings and the eccentric shaft section bearing retaining rings form height differences, and the spaces of the height differences avoid friction between the rotating eccentric shaft section bearing retaining rings and the power shaft section bearing outer supporting rings and/or avoid friction between the rotating power shaft section bearing retaining rings and the eccentric shaft section bearing outer supporting rings;
- arranging blocking sleeve rotating prevention components on the non-concentric connected retaining sleeves and the eccentric shaft sections and/or the non-concentric connected retaining sleeves and the power shaft sections, such that the blocking sleeve rotating prevention components prevent the non-concentric connected retaining sleeves from rotating relative to the power shaft sections and the eccentric shaft sections;
- arranging the non-concentric connected retaining sleeves between the power shaft section bearings and the eccentric shaft section bearings or between the eccentric shaft section bearings or between the eccentric shaft section bearings and power shaft section raking clutches;
- 3) arranging connecting rods, and arranging the connecting rods as separate snap-fitted crankshaft connecting rods or integrated sleeved crankshaft connecting rods, and sleeving the integrated sleeved crankshaft connecting rods onto the eccentric shaft section bearings;
- 4) arranging a case, and arranging the power shaft section bearings on the case, such that the power shaft section bearings support the power shaft sections and the eccentric shaft sections;
- and
- 5) arranging a power source component, such that the power source component drives the power shaft sections to rotate, and the power shaft sections drive the connecting rods in reciprocating impact.
