1 Mod 14T 8Mm Bore M4 Screw Helical Gear 2Pcs 45 Degree Right-Hand (Round Shaft)

Description: Hardened Steel Material: The helical gears are made of 1045 steel, and the surface is treated with high-temperature quenching and black oxidation. Compared with ordinary steel, they have higher hardness, strength, stability, firmness, wear resistance and stronger deformation resistance. High Efficiency: Precision engagement design reduces energy loss and ensures efficient transmission, with an efficiency of over 95%. It operates with less friction, vibration, and noise, making it suitable for use in scenarios with high requirements for quiet, such as precision instruments. How to Use: Installation: Our gears are all 45-degree left-hand gears and can be installed vertically (90 degrees) in general mechanical transmissions. Gears of the same module can be paired with any teeth to form different transmission ratios. Application: Helical gears can transmit power and change speed and torque, or transfer power between different shafts. They are used in the drive systems of electric and hybrid vehicles, machine tools, printing presses, packaging machines, textile machines, and other mechanical equipment.
