gear meshing degree:

The gear of the spur gear planetary reducer directly enters the meshing/directly exits the meshing, so the impact force of the spur gear from entering the meshing to exiting the meshing is large;

While the gears of the helical planetary reducer are meshing, the contact line is from short to long to short, which is a gradual meshing process; it can be seen that the helical gear has a small impact force from entering meshing to exiting meshing., Good meshing degree,.

overlap coefficient of gear:

The overlap coefficient of helical gears> the overlap coefficient of spur gears.

Helical gears have a helix angle. While the gears are running, both helical gears and spur gears have an end face coefficient overlap, while helical gears also have an axis surface overlap coefficient. Because helical gears have more overlapping surfaces, the carrying capacity of helical gears is higher than that of spur gears.

Transmission influence:

The gear of the helical gear is centered on the gear, and its contact surface is an oblique straight line;

The meshing contact line of a straight tooth is a straight line parallel to the axis of the gear,

Therefore, the gear error of the helical gear

Noise and vibration

The disadvantage of straight planetary gearheads is mainly that they produce vibration.

The noise and vibration of the helical planetary reducer are smaller.

Appearance:

Helical gears are gear misalignment, placed on cylindrical gears.

There is no misalignment when the spur gear is placed.
