There are mechanical elements that can continuously mesh movement and power on the wheel edge.Gear is a tooth -to -teeth mechanical parts that can mesh, and the application of gears appeared in the transmission very early.At the end of the 19th century, the principles of exhibition and toothing and the successive appearance of special machine tools and tools that used this principle. With the development of production, the stability of gear operation was valued.
Gearbox
The application of the gear box in the wind power generation unit is widely used, and it is often used in the wind power generation unit, and it is an important mechanical part. The main function of the gear box is to pass the power generated by the wind wheel under the action of the wind.The machine can get the corresponding speed.Generally, the speed of the wind wheel is very low. It is far from the speed required by the generator power generation. It must be achieved through the growth rate of the gear box gear sideline. Therefore, the gear box is also called the growth box.1. Features 1. Gearbox adopts a general design scheme, which can be transformed according to customer needs as the industrys dedicated gear box.2. Realize parallel axis, direct -intersection shafts, vertical, and horizontal universal boxes.3. Using the structure of the sound -absorbing box, the larger box surface area and the large fan, the cylindrical gear and the spiral cone gear are all adopt an advanced tooth grinding technology, which improves the temperature rise, noise and operation reliability of the whole machine, and the reliability of operation is improved, transmittingIncreased power.
gear drive
Gear transmission is the most widely used transmission form in mechanical transmission.Its transmission ratio is accurate, high efficiency, compact structure, reliable work, and long life.At present, gear technology can be reached: circular speed v = 300m/s, speed n = 105R/min, transmitted power p = 105kW, mold M = 0.004 ~ 100mm, diameter d = 1mm ~ 152.3mm.
1. Instant transmission ratio is constant.The instantaneous transmission ratio of non -round gear transmission can be designed as required.
2. The transmission ratio is large and can be used for deceleration or growth.
3. The range of speed (knuckle round weekly speed) and the range of transmission power are large.
Gear processing
The method of gear processing is a forming method, which is to cut out the tooth shape by using the forming milling cutter that is completely matched with the shape of the alginus.Cut the tooth -shaped processing methods such as scratching and teeth.Gear processing process 1. Forging blank heat mold forging is still a rough forging process widely used in automotive gear parts.In recent years, wedge horizontal rolling technology has been widely promoted in shaft processing.This technology is particularly suitable for a relatively complicated step -shaft -type blank. It not only has high accuracy, small post -processing waste, but also high production efficiency.
Gear mold
Gear modulus is the most basic parameter of the modulus wheel tooth. The modular number of straight tooth, oblique tooth and cone tooth can refer to the standard modulus series table.If the number of gears to the gear is certain, the larger the radial size of the wheels.The model series standards are formulated in accordance with the requirements of design, manufacturing and inspection.For gears with non -straight tooth, the difference between the modulus modulus MN, the end -facial modulus MS, and the axial modulus MX are all with their tooth distances (method direction tooth distance, end surface tooth distance and axis axis.The ratio of the distance between the teeth) and the circular rate is also in millimeter.For cone gears, the mold has a large -end modulus ME, average modulus MM, and small end modulus M1.For tools, there are corresponding tool mold MOs.The application of standard modulus is widely used.The standard modulus is the most basic parameter in public gear transmission, worm transmission, synchronous tooth strap transmission and spin wheels, gear coupling, bonds and other parts.It plays the role of basic parameters for the design, manufacturing, and maintenance of the above parts (see cylindrical gear transmission, worm transmission, etc.).
