Abstract
Description
technical field
[0001] The invention relates to the field of auto parts manufacturing, in particular to a remanufacturing pretreatment method for precision auto parts. Background technique
[0002] The crankshaft is the most important part of the engine. It bears the force transmitted by the connecting rod and converts it into torque through the crankshaft output and drives other accessories on the engine. The crankshaft is subjected to the centrifugal force of the rotating mass, the periodically changing gas inertial force and The combined effect of reciprocating inertial force makes the crank bearing subject to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, work uniformly, and have good balance; when maintaining and repairing the engine, it is necessary to The crankshaft is disassembled and inspected to determine whether the crankshaft can be used again. If it cann...
