I. Core Positioning

Helical cylindrical gears are core components for mechanical transmission. Designed with helical tooth profiles, they enable smooth power transmission and are suitable for high-speed, heavy-load, and precision transmission scenarios. Compared with spur gears, they offer significant advantages in stability, load-bearing capacity, and noise reduction, and are widely applied in core equipment across various industries.

II. Core Advantages

Smooth Transmission & Low Noise: Progressive meshing of helical teeth enables multi-tooth simultaneous contact (contact ratio is 2-3 times that of spur gears), significantly reducing impact and vibration, and lowering operating noise by 30%-50%;
Superior Load-Bearing Capacity: 300% increase in tooth contact area ensures uniform load distribution. Under the same volume, the load-bearing capacity is 20%-40% higher than that of spur gears, and the service life is extended by 2-3 times;
High Efficiency & Compact Structure: Transmission efficiency reaches 95%-98%. High reduction ratios can be achieved by adjusting the helix angle (8°-25°), featuring a compact structure that saves installation space;
Versatile Adaptability: Supports parallel shaft/staggered shaft transmission, compatible with complex working conditions such as high speed (up to 10,000rpm+), heavy load, and precision positioning;
Reliable Manufacturing Process: Adopts high-quality alloy steel/powder metallurgy materials, undergoing carburizing and quenching, precision grinding processes. Tooth profile error is controlled to DIN Class 3/ISO Class 5 standards, with hardness up to HRC60-62.
