- Residual Stress And Fatigue PerformanceGear transmission is widely applied in various mechanical equipment due to its advantages of accurate transmission ratio and high transmission efficiency. China has now become a major gear-producing country—with the output value of the gear industry exceeding 236 billion yuan in 2017, ranking first
- Influencing Factors And Fault Prevention of Gearbox Oil LeakageAs a core component for transmitting power and motion in mechanical equipment, the reliability and stability of gearbox operation are crucial. However, oil leakage is one of the most common faults of gearboxes. It not only causes lubricating oil waste and environmental pollution but also leads to in
- Gears: Fundamental Principles, Types, And Industrial ApplicationsGears are indispensable mechanical components in power transmission systems, functioning to adjust speed, torque, and direction of motion between rotating shafts. With a history spanning centuries—from ancient wooden gears to modern precision-engineered components—they remain the backbone of countle
- Why A Single Bearing Failure Triggers Total Gearbox Collapse: Industry InsightsIn the practical application of traction gearboxes for rail transit, a common phenomenon emerges during disassembly and inspection: while one bearing shows obvious damage, other components such as gears, adjacent bearings, seals, and even the gearbox housing also exhibit abnormalities to varying deg
- Gear Transmission: Core Principles, Types, Applications And Future TrendsAs a fundamental mechanical power transmission technology, gear transmission plays an irreplaceable role in modern industry. From the precision movement of wristwatches to the heavy-duty operation of industrial machinery, from automotive transmissions to aerospace engines, gears realize the efficien
- Failure Analysis of Gear Ring Ellipticity Out-of-Tolerance Caused by Improper Heat Treatment Clamping1. Introduction: A Persistent Challenge in Gear Ring ManufacturingIn the production of gear ring components (including large-module gears, gear rings, and rim gears), ellipticity out-of-tolerance after heat treatment is a long-standing issue. However, on-site judgments often misattribute the problem
- Knowledge of Involute Splines: Strength Depends on Diameter, Not ModulusInvolute splines are crucial power transmission components in mechanical drive systems, renowned for their excellent mechanical strength and smooth transmission characteristics. They find widespread application in aircraft, automobiles, heavy machinery, construction machinery, and other fields. A co
- Application of Couplings1. Overview of CouplingsA coupling is a key mechanical component designed to connect two shafts (such as the output shaft of a motor and the input shaft of a working machine) in power transmission systems. Its core functions include transmitting torque, compensating for relative misalignments betwee
- Tapered Roller Bearings: Get Axial Clearance Wrong, And All Design Efforts Go To WasteTypical data shows that when axial clearance is 10%–20% below the recommended value, the bearing's service life can be reduced by 40%–60% due to excessive contact stress and lubrication failure. Conversely, a clearance 30% above the optimal range only shortens life by 10%–15% and mainly affects oper
- Wind Turbine Gearbox: Current Status, Layout, And Future TrendsWind turbine gearboxes are one of the core components in wind power generators, located between the rotor and the generator. They undertake the crucial task of converting the low-speed mechanical energy captured by the rotor into the high-speed mechanical energy required by the generator. As the "tr
