Spur Gear

A gear is a product with teeth added around a rotating wheel. Gear transmission mechanisms are widely used in the transmission of rotary motion, rotational speed, and rotational direction.

1. Smooth and reliable transmission:

Spur gear transmission is basically continuous meshing, and the meshing area is large, so the impact and noise during transmission are relatively small.

This smooth transmission characteristic makes spur gear widely used in high-demand occasions, such as aircraft, automobiles and other mechanical equipment.

2.Long service life:

Spur gear transmission has no sliding friction, so its wear and fatigue are relatively small.

This also makes the spur gear have a long service life, reducing the maintenance cost and replacement frequency of the equipment


Types and Characteristics of Gear Transmission

①Parallel Transmission    Rotation/power transmission between two parallel meshing gears    Straight gear + Helical gear + Internal gear + Herringbone gear + Helical internal gear

②Angular Transmission    Rotation transmission with angle transformation between intersecting axes    Straight bevel gear + Spiral bevel gear    Bevel gear

③Cross Transmission    Rotation transmission between non-intersecting and parallel axes    Screw gear    Worm wheel + Worm

④Linear Transmission    Displacement transmission from rotation to linear motion or vice versa    Straight rack + Helical rack

Advantages:

* No transmission delay, unlikely to jump or slip teeth

*Relatively free transformation of transmission direction

* Relatively free adjustment of transmission speed

*Capable of high-power transmission, as well as high-load and high-torque transmission

* Less impact from environmental factors such as temperature, humidity, and oiliness

* Suitable for small spaces
