The gearbox is like the "brain" of a car, smartly shifting between gears to help the car go faster or save on fuel. Without it, our cars wouldn't be able to "shift gears" to improve efficiency as needed.
1. Pressure Angle
To maintain a consistent power output, the force (F) needs to remain constant. When the pressure angle (α) is heightened, the normal force (Fn) acting on the tooth surface must also rise. This increase enhances the pitch and meshing forces on the tooth surface, in conjunction with frictional forces, which subsequently elevates vibration and noise levels. Despite the gear center distance error not impacting the precise engagement of involute tooth profiles, any variation in this distance causes periodic alterations in the working pressure angle.
2. Coincidence
During load transmission, the gear teeth experience varying degrees of deformation. Consequently, upon engagement and disengagement, an engagement impulse is induced along the engagement line, resulting in torsional vibration and noise generation.
3. Gear Accuracy
The noise level of gears is substantially impacted by their precision. Consequently, the primary strategy for mitigating gear motor noise is to improve gear precision. Attempts to reduce noise in gears of low accuracy are ineffective. Among the individual errors, the two most significant factors are the tooth pitch (base or peripheral) and the tooth shape.
4. Gear Parameters and Structural
Configuration Gear parameters encompass the diameter of the gear, the width of the teeth, and the structural design of the tooth blank.
