The basic introduction of gears

Gear; A mechanical component with teeth on the rim that can continuously engage to transfer motion and power is a mechanical component with teeth that can mesh with each other. The diameter of the big gear is twice that of the small one. If the big gear does not move, how many times does the pinion revolve around the big one? Conversely, if the pinion does not move, how many times does the big pinion revolve around the pinion? The big gear does not move, the small gear along the big gear revolution one week, the small gear rotation one week; When the pinion does not move, the big gear rotates once around the pinion, and the big gear rotates once and a half, i.e., once at 240°, once and a half at 360°, two times at 480°, and three times at 720°.
Gear is a mechanical part with teeth that can mesh with each other. It is widely used in mechanical transmission and the whole mechanical field. Modern gear technology has reached: gear modulus 0.004 ~ 100 mm; Gear diameter from 1 mm to 150 meters; Transmission power up to 100,000 kilowatts; Speed up to hundreds of thousands of RPM; The highest circumferential speed is 300 m/s.

Role of gears

Gear is a mechanical part with teeth that can mesh with each other. The application of gear in transmission appeared very early. At the end of the 19th century, the development of the principle of tooth cutting method and the use of this principle of tooth cutting special machine tools and tools have appeared, with the development of production, the smoothness of gear operation by attention. The role of gear is to transfer the rotation of one shaft to another shaft, but also to achieve deceleration, increase, change and reverse action.

Advantages and disadvantages of helical gears:

1 because the meshing surface by small - large - small, meshing smooth, small impact, low noise;

2 large bearing capacity, improve life and stability;

3zmin small not easy root cutting, small volume;

4 but the axial thrust, herringbone gear - no axial thrust, but create trouble.

Helical gear transmission consists of two helical gears meshing together. Purpose: to transfer the motion between two wrong axes in space. Features:

1 Spiral direction can change the center distance, transmission ratio

The steering can be changed by spiral rotation

3 quick wear

4 point contact

5 the axial force is small

advantages

(1) Good meshing, smooth transmission and low noise.

(2) Large degree of overlap, reduce the load of each pair of gear, improve the bearing capacity of gear.

(3) the minimum number of teeth without root cutting is small.

defect

(1) The manufacture of herringbone gear is complicated
