Complex working conditions such as heavy impact, high-frequency reciprocating, dust corrosion, and continuous full-load operation are the main causes of fatigue fracture, wear and scrapping, and premature failure of eccentric shafts. Most manufacturers only rely on general experience in selecting materials and do not match materials based on actual working conditions. They blindly select ordinary carbon steel and inferior alloy steel, resulting in insufficient impact resistance and poor wear and fatigue resistance of the eccentric shaft, and cracks, deformation, wear and other faults in a short period of time., shaft breakage and other faults, causing frequent equipment downtime for maintenance, greatly increasing production and operation and maintenance costs, and seriously affecting the continuous operation efficiency of the equipment.

Equipment operating jitter, abnormal noise, heating and stagnation, and sudden drop in service life are mostly due to poor cooperation between the eccentric shaft and the bearing and connecting rod. Many customized eccentric shafts only focus on the appearance size, ignoring the roundness, cylindricity, smoothness and fitting tolerance accuracy of the shaft position, resulting in excessive, tight assembly clearance or uneven stress. Fitting deviation will cause eccentric operation and increased local friction, resulting in problems such as rapid bearing wear, loose connecting rods, and deviation of the accuracy of the whole machine. It not only frequently causes equipment failures and increases maintenance costs, but also leads to unstable output of the whole machine. Production capacity decline, seriously affects the stability and service life of the equipment.

When equipment companies customize non-standard eccentric shafts, the core problem they are most worried about is the leakage of drawings. The eccentric shaft drawings include core structural parameters, eccentric data, suitable size and supporting technology of the whole machine, and are the core technical assets of the enterprise. Traditional processing plants have many drawing circulation links, loose authority and lack of confidentiality mechanism, which are easy to cause problems such as drawing leakage, parameter outflow, model imitation and scheme plagiarism, which directly lead to theft of new product R & D achievements of enterprises, imitation of core models by peers, damage of market competitiveness and loss of orders, bringing irreversible economic losses and technical risks to enterprises.

Many equipment manufacturers generally encounter problems of poor consistency when purchasing eccentric shafts in batches: large deviations in the size of the shaft body of the same batch, uneven eccentricity, varying hardness, and obvious fluctuations in dynamic balance data. This will lead to confusion in assembly gaps of the whole machine, jitter in equipment operation, uneven noise levels, and uneven performance of batch equipment. It not only greatly increases the difficulty of assembly and debugging, causing time-consuming rework, but also makes the failure rate of finished equipment unstable and after-sales problems Frequent, seriously affecting product reputation and market quality stability, is a core process pain point in mass production.

Equipment factories often face core problems in customizing eccentric shafts: traditional processing processes are cumbersome, process connection is lagging, customization cycles are lengthy, sample delivery is slow, and mass production delivery is uncontrollable. Once you encounter scenarios such as new product research and development testing, emergency replacement of equipment parts, and urgent production of orders, excessive delivery times will directly slow down the research and development progress, cause equipment to be suspended and delayed in the delivery of the whole machine, causing production capacity losses and Double losses such as customer loss have become a key bottleneck restricting production operations.
