Gear moving, so with the feeling!  Machining turns out to be beautiful too

Let’s start with a batch of gear animations

• Constant velocity joint

• Satellite bevel gear

epicyclic transmission

The input is pink carrier and the output is yellow gear.  Two planetary gears (blue and green) are used to balance the forces applied to the input and output. 

• Cylindrical gear drive 1

cylindrical gear drive 2

Each gear (screw) has only one tooth, the width of the end face of the gear must be greater than the distance between tooth shafts 

• Four pinions rotate in opposite direction

 This mechanism is used instead of 3 bevel gear drives to avoid the use of vertical shafts. 

• Gear coupling 1
• Internal gears have no bearings.

• Gear coupling 2
• Internal gears have no bearings.

• A gear reducer with equal number of teeth

• Helical gear drive 1
• Auxiliary external screw drive.

• Helical gear drive 2
• Auxiliary inside screw drive.

• Helical gear drive 3

• Helical gears drive eccentrically

• Internal engagement simulation engine

• Internal engagement simulates slide drive

• Planetary gears simulate rocking motion

Cylindrical gear drive  

When two gears engage and the spindles of the gears are parallel to each other, we call it parallel-shaft gear transmission.  Also called cylindrical gear drive.  

Specifically divided into the following several aspects: spur gear transmission, parallel shaft helical gear transmission, miter gear transmission, rack and pinion transmission, internal gear transmission, cycloid gear transmission, planetary gear transmission and so on.

Herringbone gear drive

Rack and pinion drive

Bevel gear drive  

If two spindles are not parallel to each other, it is called intersecting shaft gear drive, also known as bevel gear drive.  

Specifically divided into: straight tooth cone gear drive, bevel gear drive, curve tooth bevel gear drive. 

• Straight tooth cone wheel drive

Helical bevel gear drive

• Curved bevel gear drive

Staggered shaft gear drive  

When the two spindles are interlaced on different surfaces, it is called staggered shaft gear transmission.  There are staggered helical gear drive, hypoid gear drive, worm drive and so on.
