NameHelical Bevel Gearbox, also known as Planetary Helical Bevel Gearbox.
Principle: Utilizes cycloidal pin tooth meshing and planetary transmission principle.
StructureMainly divided into the input section, the reduction section, and the output section.
II. Working Principle
As the input shaft rotates with the eccentric sleeve, due to the characteristics of the involute wheel's tooth profile curve and the limitation of the needle gears, the involute wheel's motion becomes a plane motion with both rotation and revolution. When the input shaft rotates one full cycle clockwise, the eccentric sleeve also rotates one full cycle, causing the involute wheel to rotate one tooth in the opposite direction to achieve deceleration. With the help of the W output mechanism, the low-speed self-revolutionary motion of the involute wheel is transmitted through the pin shaft to the output shaft, thus obtaining a lower output speed.
Section 3: Features and Advantages
High transmission efficiencyAchieves a high reduction ratio of 1:87 and over 90% efficiency in a single-stage transmission. If a multi-stage transmission is used, the reduction ratio can be even greater. The reduction ratio of a single-stage transmission is 9.87, double-stage transmission reduction ratio of 1215133, multi-level combinations can reach tens of thousands.
Compact and small in structureDue to the use of planetary transmission principles, the input and output shafts align on the same axis, resulting in a compact machine design.
Smooth operation with low noiseThe involute needle gear has a higher number of teeth, a larger overlap coefficient, and a mechanism for balanced components, which keeps vibration and noise to a minimum.
Utilize reliable and long-lastingThe main components are made of bearing steel material, heat treated for high strength, and feature rolling friction in some transmission contacts for durability.
Well-designed, easy to maintainEasy to disassemble and install, with few parts and simple lubrication, trusted by users.
