Product Description
Introducing a custom gear set for electric airsoft guns, designed for high quality and high performance.
Born from H.T.G. Basic's "Kuro Concept," this gear set is compatible with Ver.2, Ver.3, and Ver.6 gearboxes, and is the industry's first to adopt spiral gears and all-helical gears.
With five gear ratios available: 18:1, 16:1, 13:1, 12:1, and 9:1 (DSG), and a total of 10 variations including conventional spur gear types, it expands customization possibilities.

【Integrated Design with High-Precision CNC Machining】
High-precision integrated design through CNC (Computer Numerical Control) machining eliminates compatibility issues, noise, and transmission efficiency variations between gears. It ensures optimal performance without the need to worry about combining with products from other manufacturers.

【Adoption of High-Strength Steel Material】
Utilizes S45C and 20CrMnTi (chromium-manganese-titanium alloy gear steel). The material and hardness of each part are adjusted to match the characteristics of electric airsoft guns, improving durability and reliability.

【Changes for Higher Speed and Easier Setup】
To accommodate motors with instantaneous rotation increase, such as brushless motors, improved electronic trigger response, or pre-cocking, the tappet pin position of the sector gear has been moved to a later position than conventional types.
This increases the freedom and simplicity of tappet plate settings.

Sector cutting processing is based on cutting from the front tooth, allowing for settings with minimal change in cutoff timing while adjusting the relationship between nozzle opening timing and the piston.
Additionally, nozzle closing timing can be adjusted by cutting the lower part of the tappet plate wing, improving the freedom of processing shape and making nozzle control easier.

Note: There are some differences from conventional settings, so please test thoroughly before use.

【Effects and Advantages of Spiral and Helical Gears】
◇Spiral Gear (adopted for pinion gear and bevel gear)
・High torque transmission efficiency: Due to the helical tooth surface contact, multiple teeth mesh simultaneously. This ensures smooth torque transmission and resistance to heavy loads.
・Noise reduction: Increased contact area between teeth and smooth meshing significantly reduce vibration and noise.
・Improved durability: Stress on the tooth surface is dispersed, resulting in less wear and a longer lifespan.
*The pinion gear included is for D-type motor shafts.
Please note that it cannot be used with O-type shafts such as our "Kuro Motor".

◇Helical Gear (adopted for counter gear and sector gear)
・Smooth operation: The obliquely cut tooth profile ensures continuous meshing with less impact.
・High rotation performance: Stable transmission is possible even at high rotation speeds, contributing to an improved rate of fire.
・Improved quietness: Compared to spur gears, contact is smoother, reducing noise within the gearbox.

◇Spiral Bevel Gear Specification Change
・Due to its structure, the spiral bevel gear is difficult to integrally mold and is therefore an assembly type.
・The anti-reversal latch drum has been improved from conventional MIM molding to CNC machining to reduce play.
・The number of anti-reversal teeth has been increased from 5 to 6, and as an advantage of separate CNC machining, they have a smoother shape.

【Further Performance Improvement with Precise Shimming】
Precise shimming minimizes backlash (play) between gears, which is expected to improve efficient torque transmission and response.

【Gear Ratio Lineup】
18:1: Standard gear ratio for balanced performance.
16:1: Improved rate of fire and moderate torque.
13:1: Ideal for users seeking high-speed firing.
12:1: Further pursuit of increased rate of fire.
9:1 (DSG): Dual Sector Gear specification for incredible rates of fire and crisp semi-auto shots due to short stroke.
*The gear ratio of the 9:1 (DSG) set is 18:1, but since the sector gear performs double the action, the effective gear ratio is 9:1.

【Set Contents】
・Sector Gear
・Counter Gear (Spur Gear)
・Bevel Gear
・Pinion Gear
・Hex Wrench
・Grub Screw for Installation

【Caution】
・Replacing the pinion gear on a brushless motor requires skill and knowledge. If you are not confident or do not have the proper tools, please consult a specialized shop.
・Cannot be used in combination with gears from other manufacturers or conventional spur gears.
・The sector gear's piston pulling teeth on the spiral helical gear set are 16 spur teeth (8 teeth for DSG).
・Installation may require processing and adjustment.
・Apply threadlocker to the grub screw for pinion fixation.
