What Causes a Gasoline Generator to Seize Up and Become Immovable?

[MackenzieMarie]

The reasons why a gasoline generator seizes up and becomes immovable are: 1. Poor quality of the crankshaft and bearings, with subpar smoothness of the journal and bearing surfaces; 2. Incorrect installation of the main or connecting rod bearings, improper adjustment of clearance, or excessive or insufficient contact area, all of which make it difficult to form an oil film between the shaft and bearings; 3. Severe wear and failure of the oil pump gears, leading to reduced oil pressure and difficulty in supplying oil to designated lubrication points, resulting in dry friction of the bearings; 4. Blockage of the oil passages by contaminants. A gasoline generator typically consists of components such as the stator, rotor, end cover, and bearings. It generates kinetic energy by burning fuel in the cylinder, driving the piston inside the engine cylinder to reciprocate. This motion drives the connecting rod attached to the piston and the crank connected to the rod, producing a reciprocating circular motion around the crankshaft center to output power.
