What are the types of gears?

There are many types of gears. The following are some common styles for your reference. If you are unclear, you can consult EP Processing for free.

1. It can be divided into circular rotating gear train, conversion gear train and fixed axis gear train, etc.

2. Internal gear and external gear.Among them, the steering of the two inner gear wheels is the same, and the steering of the outer gear wheels is opposite.

3. Cross-axis helical gear transmission, hypoid gear transmission, worm gear transmission.

4. Straight-tooth bevel gear transmission, helical bevel gear transmission, and arc-tooth bevel gear transmission.

5. Herringbone cylindrical gear external meshing transmission.

6,Spur gearExternal meshing, spur gear internal meshing, spur gear rack meshing transmission.

7. The helical cylindrical gear meshes externally, the helical cylindrical gear meshes internally, and the helical gear rack meshes for transmission.

In this way, you may not be very clear about what each series has. Then, the following is based on the relative tooth line of the product.gearThe three conditions of the direction of the bus bar, the shape of the tooth curve, and the relative position of the two shafts classify the common gear products.

XNUMX. According to the direction of the tooth line of the product relative to the gear bus, the following types can be subdivided:

Straight teeth, helical teeth, herringbone teeth and curved gears.

XNUMX. According to the shape of the tooth curve of the product, the following types can be subdivided:

Involute teeth, cycloid teeth and arc gears.

XNUMX. According to the relative position of the two axes, the following types can be subdivided:

1. Two-axis parallel plane gear transmission:

Cylindrical gear transmission: straight teeth, helical teeth, herringbone teeth,Gear racktransmission.

2. Space gear drive with two non-parallel shafts:

a. The two shafts are misaligned: hyperbolic bevel gear, helical gear, worm gear and worm drive.

b. Two shafts intersect: Straight tooth, helical tooth, curved tooth, bevel gear drive.

The above is the description of gear types shared by the EP editor today, including but not limited to, tomorrow will share with you the characteristics, shortcomings and main uses of gear transmission products, so stay tuned!
