Gear transmission refers to a device that transmits motion and power through gear pairs, and it is a widely used mechanical transmission method in modern equipment. Its transmission is relatively accurate, efficient, compact in structure, reliable in operation, and has a long service life. There are many types of gear transmission methods, and this article provides examples of different gear transmission methods.

01 Cylindrical gear transmission

When two gears mesh and the main axes of the gears are parallel to each other, we call it parallel axis gear transmission. Also known as cylindrical gear transmission. Specifically divided into the following aspects: spur gear transmission, parallel shaft helical gear transmission, herringbone gear transmission, gear rack transmission, internal gear transmission, cycloidal gear transmission, planetary gear transmission, etc.

1) Spur gear transmission

2) Parallel axis helical gear transmission

3) Herringbone gear transmission

4) Gear and rack transmission

5) Internal gear transmission

6) Planetary gear transmission

02 bevel gear transmission

If two main axes are not parallel to each other, it is called intersecting axis gear transmission, also known as bevel gear transmission. Specifically divided into: spur bevel gear transmission, helical bevel gear transmission, curved bevel gear transmission, etc.

1) Straight bevel gear transmission

2) Helical bevel gear transmission

3) Curved bevel gear transmission

03 Interlocking shaft gear transmission

When the two main axes are staggered in space, it is called staggered shaft gear transmission. There are staggered shaft helical gear transmission, hypoid gear transmission, worm gear transmission, etc.

1) Interlocking shaft helical gear transmission

2) Hyperbolic gear transmission

3) Worm gear transmission

04 Ten uncommon gear transmissions

1. Cylindrical gear transmission 1

2. Cylindrical gear transmission 2

Each gear (screw) has only one tooth, and the width of the gear end face must be greater than the gear shaft spacing.

3. Four small gears rotate coaxially and in opposite directions

This mechanism is used to replace a bevel gear transmission to avoid the use of vertical axes.

4. Gear coupling 1

The internal gears do not have bearings.

5. Gear coupling 2

The internal gears do not have bearings.

6. Internal and external gears

7. Gear reducer with equal number of teeth

This is a result that is usually considered impossible to achieve.

8. Spiral gear transmission 1

Auxiliary external spiral transmission.

9. Spiral gear transmission 2

Spiral transmission inside the auxiliary device.

10. Spiral gear transmission 3
