Description
Technical Field
The utility model belongs to the technical field of mechanical transmission technique and specifically relates to a herringbone tooth planet wheel.
Background
The helical gears have transverse force on the shaft, and in order to eliminate the force, one gear is made into the helical gears with opposite symmetrical directions to eliminate the force, and the helical gears look like a personal character, are called herringbone gears for short, and have the advantages of high overlap ratio, small axial load, high bearing capacity and smooth operation. Planetary gears refer to a gear system that can rotate around its own rotation axis like a fixed-axis gear, and the rotation axis of the planetary gears rotates along with the axis of other gears along with a planet carrier, and compared with the common gear transmission, the planetary gear transmission has many unique advantages, the most remarkable characteristic is that power can be split when power is transmitted, and an input shaft and an output shaft are on the same horizontal line, so the planetary gear transmission is widely applied to speed reducers, speed increasers and speed changers in various mechanical transmission systems, and particularly, the planetary gear transmission is widely applied to aircrafts and vehicles (particularly heavy vehicles) due to the characteristic of high load and high transmission ratio. A long tool withdrawal groove is reserved in the middle of the integral planet wheel, the machining is difficult, the total tooth width is long, the spot space is reserved, the welding type planet wheel is welded by electron beams, the precision is lost due to deformation after welding, and the welding cost is high.
