Helical gears: the core of precision transmission - Decoding the technical advantages of Shandong Prior Machinery Manufacturing Co., Ltd.!
1. Why are helical gears an ideal choice for high-speed and heavy-load transmission?
With its unique helical tooth design, helical gears have achieved the core advantages of smooth transmission, low noise and strong load-bearing capacity. Compared with spur gears, the contact line of its tooth surface is distributed obliquely, and multiple teeth are involved in the work during the meshing process, which effectively disperses the load and reduces impact vibration. Shandong Prior Machinery Manufacturing Co., Ltd. relies on high-speed hobbing and grinding machine technology to accurately control the helix angle (8°-25°) of helical gears to ensure its stable operation in heavy-load scenarios such as wind power equipment and construction machinery, meeting customers' core needs for high torque and low loss.

2. How does the "helix angle" of helical gears affect performance? How does Prior overcome this technical difficulty?
The helix angle is a key parameter of helical gears, which determines the axial force, transmission efficiency and noise level. Through modular design and CNC machining centers, combined with heat treatment deformation prediction technology, Prior has controlled the helix angle error within ±0.1°, which not only ensures high overlap (increased to more than 2.0), but also reduces axial thrust by optimizing tooth surface modification technology. The special gear heat treatment equipment equipped on its production line further enhances the tooth surface hardness and fatigue resistance, increasing the product life by more than 30%.

3. How does Prior's helical gear achieve "precise adaptation" under complex working conditions?
In response to the needs of different industries, Prior provides customized helical gear solutions:
Wind power field: using large modulus (3-8 mm), high precision (DIN 6 grade) helical gears, matching the parametric modeling technology of the inner helical gear ring, to adapt to the harsh load of large megawatt gearboxes;
Automobile transmission: through the combination of hobbing + grinding process, the tooth profile error is ≤0.01 mm and the surface roughness Ra≤0.8 μm, meeting the extreme requirements of electric vehicles for low noise and high speed;
Heavy machinery: combining carburizing hardening treatment and tooth root transition fillet optimization technology to improve impact resistance and avoid the risk of fracture caused by stress concentration.

4. How does Prior's "integrated gear production line" enable helical gear manufacturing?
The company's 12,000 square meter intelligent production base integrates three core links: high-speed gear hobbing, CNC grinding, and precision testing:
High-speed gear hobbing machine: supports a module range of 1-20 mm, a maximum processing diameter of 1500 mm, and is suitable for batch production of helical gears of multiple specifications;
Gear grinding process: The dynamic dressing technology of the worm grinding wheel is used to achieve a tooth surface accuracy of DIN 5-7, ensuring the dimensional stability of the gear after carburizing and quenching;
Full-process quality control: Through the three-coordinate measuring instrument and the gear meshing detection system, the cumulative pitch error (Fp≤0.04 mm) and tooth deviation (Fβ≤0.01 mm) are strictly monitored.
