Hypoid Angle Gear Kit 80 Degree Engagement For Micro Reducer

Hypoid Angle Gear Kit 80 Degree Engagement For Micro Reducer

1. The technical principle and structural characteristics
① Non-standard shaft intersection angle design

• 80° Shaft Angle: Different from the 90° vertical transmission of traditional hypoid gears, the input and output shafts of this gear are arranged at an angle of 80°, which is suitable for scenarios where space is limited or non-orthogonal transmission is required.
• Axis offset: The meshing point of the hypoid gear is not on the axis, but the offset design optimizes the contact stress distribution of the tooth surface to improve the bearing capacity.

② Gear grinding process and material characteristics

• Hard tooth surface processing: Carburizing and quenching process is adopted, the hardness of the tooth surface is up to 56-62HRC, and after high-precision grinding, the roughness of the tooth surface Ra≤0.8μm, and the accuracy level can reach ISO 10 or above, which significantly reduces wear and noise.
• Continuous hobbing technology: Using a full CNC spiral bevel gear machining machine, continuous indexing cutting through a double-layer cutterhead, avoiding the accuracy loss of traditional intermittent tooth splitting, and supporting independent parameter adjustment of concave and convex surfaces.

③ Miniaturized design

• Compact design: Diameters as small as 38 mm are available and the weight is light, making them suitable for integration in precision equipment.
• Hollow shaft configuration: Some models use hollow output shaft for direct mounting of couplings or lead screws, simplifying mechanical design.

2. Performance advantages

① High reduction ratio and high efficiency

• Single-stage gear ratio up to 300:1: Compared with worm gear reducers (efficiency of only 60%-70%), hypoid gears have an efficiency of more than 90% and no self-locking, which is suitable for scenarios that require bidirectional transmission.
• Low-noise operation: The helical tooth meshing method reduces the impact, and with the gear grinding process, the noise can be controlled below 60dB, which is better than that of ordinary bevel gears.

② High load capacity and long life

• Increased contact strength: After carburizing and quenching, a 0.3-0.5mm hardened layer is formed on the tooth surface, and the contact stress can be increased by more than 30% in combination with the optimized tooth surface contact zone design.
• Shock resistance: Suitable for frequent start-stop or load fluctuation conditions.

③ Spatial adaptability

• Flexible installation: It supports flange installation, foot installation and other methods, and the output shaft can be customized to adapt to complex mechanical structures.
• Offset distance optimization: By adjusting the axis offset, the strength of the small wheel can be balanced with the transmission efficiency.

3. Typical application scenarios
① Industrial automation

• Collaborative robot joints: For example, the wrist joints of dual-arm robots use 80° hypoid gears to achieve high torque density transmission while reducing joint volume.
• Precision positioning stage: A wafer handling mechanism in semiconductor equipment that ensures positioning accuracy (repeatability error ≤± 1 arc minute) by utilizing high reduction ratio and low backlash characteristics.

② Medical & Food Machinery

• Surgical instrument drives: Rotating joints, such as endoscopes, require low noise, long life, and FDA-compliant materials.
• Food packaging equipment: the indexing mechanism of the high-speed filling machine needs to withstand frequent start-stop impacts, and the wear-resistant characteristics of the hypoid gear can extend the maintenance interval.

③ Aerospace & Military

• UAV flight control system: The micro reducer is used for servo control, and the 80° axis intersection angle optimizes the layout of the internal space of the fuselage.
• Missile Guidance Devices: In extreme temperatures (-50°C to 125°C) and vibration environments, carburized quenched gears are more reliable than traditional worm gears.

4. Maintenance and selection suggestions

• Lubrication requirements: The lubricating oil needs to be replaced after 300 hours of first operation, and the oil level should be checked every 3000 hours or half a year ther
• eafter to avoid mixing mineral oil with synthetic oil.
• Oil seal inspection: Ensure that the oil seal is soaked in oil during long-term storage to prevent lip hardening; If oil leakage is found during operation, the oil seal should be replaced in time.
