Customize Transmission Gears Spur Gear for stable power transmission performance

1) Description of Spur Gear

From the perspective of precision and low-noise adaptation, spur gears are straight-toothed gears manufactured with high precision and featuring optimised tooth profiles. By controlling pitch errors, tooth surface roughness, and meshing clearance, they achieve low-noise, high-precision power transmission, making them suitable for applications demanding high operational stability.

2) Characteristics of Spur Gear

Characterised by high machining precision (tooth profile tolerances of IT5-IT6 grade, surface roughness Ra≤0.8μm), with tooth profiles featuring either a modified or barrel design (to reduce meshing impact). Materials predominantly comprise high-strength alloys (such as 20CrMnMo) enhanced through heat treatment; Advantages include low operational noise (no-load noise ≤65dB), high transmission accuracy (transmission error ≤0.01mm), and exceptional wear resistance (tooth surface hardness 58-62HRC). These gears maintain stable performance during prolonged operation, minimising vibration impact on equipment.

5) Application

Suitable for equipment with stringent requirements for precision and noise levels, such as feed transmission systems in precision machine tools; miniature spur gears in instruments and gauges (e.g., flow meters, counters); transmission components in medical devices (e.g., infusion pumps, ventilators); lightweight precision transmission gears in aerospace equipment; and transmission gears in auxiliary systems of new energy vehicles (e.g., air conditioning compressors, power steering pumps).
