Precision 90°Angle Gear for Industrial Planetary Speed Reducer Use
The 90-degree angle gear is the core component of the planetary
reducer to achieve orthogonal power transmission (the input/output
shafts are staggered at 90 degrees). Its performance directly
determines the torque capacity, transmission efficiency and life of
the reducer.
90-degree angular gear function logic chain:
Planetary gear train output → angular gear pair (bevel gear) meshing → power transfer 90° → load shaft output
Note: Compared to worm gear solutions, bevel gear angular
transmission efficiency is increased by 15%-25% and lifespan is
increased by 2-3 times.
Technical Features of Planetary Reducer 90-Degree Angle Gears
(I) High Precision and Low Backlash
The bevel gears utilize a helical tooth design with a curved tooth
contact line, resulting in a smoother meshing process and reduced
vibration and noise. Furthermore, precision grinding processes
(such as four-axis CNC grinding) control tooth profile accuracy to
ensure minimal backlash (tooth clearance), meeting the highest
positioning accuracy requirements.
(II) Compactness and High Rigidity
Space Optimization: The 90-degree right-angle layout significantly
reduces the axial dimensions of the equipment, making it
particularly suitable for confined spaces (such as robotic arm
joints and side drive units in automated production lines).
Structural Reinforcement: The gearbox is constructed of ductile
iron or high-strength alloy steel, supported by rigid bearings, to
withstand high radial loads and impact forces.
(III) Efficient Transmission and Durability
Transmission Efficiency: Spiral bevel gears achieve an efficiency
exceeding 95%, significantly higher than worm gear transmissions
(approximately 60%-70%).
Life Guarantee: The tooth surfaces undergo a carburizing and
quenching treatment, achieving a hardness of HRC58-62. A forced
lubrication system reduces wear and extends service life.
Typical Application Scenarios for Planetary Reducers with 90-Degree
Angle Gears
(I) Industrial Automation Equipment
In mechanisms requiring tight steering, such as robot joints and
indexing tables, 90-degree angle gears combined with planetary
reducers achieve high-precision positioning and optimized spatial
layout.
(II) Heavy-Duty Machinery Systems
In mining conveyors and metallurgical rolling equipment, for
example, their high-rigidity structure can withstand heavy load
shocks while simplifying drive train design through right-angle
output.
(III) Precision Machining Machinery
In the feed systems of CNC machine tools, the smooth steering
characteristics of bevel gears can reduce cutting vibration and
improve surface quality.
