The gearbox is widely used in wind turbines and is an important mechanical component. Its main function is to transmit the power generated by the wind turbine under the action of wind to the generator and obtain the corresponding speed. Usually, the speed of the wind turbine is very low and far from the required speed for generator power generation. It must be achieved through the acceleration effect of the gearbox gear pair, so the gearbox is also called an acceleration gearbox. 1、 Feature 1: The gearbox adopts a universal design scheme and can be customized into industry-specific gearboxes according to customer needs. 2. Implement a universal box for parallel axis, orthogonal axis, vertical and horizontal axis, reducing the types of components and increasing the specifications and models. 3. Adopting a sound-absorbing box structure, a larger box surface area, and advanced gear grinding technology for large fans, cylindrical gears, and spiral bevel gears, the temperature rise, noise reduction, and operational reliability of the entire machine are improved, and the transmission power is increased.

Gear transmission is the most widely used form of transmission in mechanical transmission. It has accurate transmission ratio, high efficiency, compact structure, reliable operation, and long service life. The current achievable indicators of gear technology are: circumferential speed v=300m/s, rotational speed n=105r/min, transmitted power P=105KW, module m=0.004-100mm, diameter d=1mm~152.3mm.

feature

1. The instantaneous transmission ratio remains constant. The instantaneous transmission ratio of non-circular gear transmission can be designed according to the required variation law.

2. The transmission ratio range is wide and can be used for deceleration or acceleration.

3. The range of speed (referring to the circumferential speed of the joint) and transmitted power is large.

One method of gear machining is the forming method, which uses a forming milling cutter that perfectly matches the shape of the gear groove to cut the tooth profile, such as milling teeth; Another method is the generating method, which uses the meshing motion between the cutting tool and the passive gear to cut the tooth profile, such as hobbing and hobbing. Gear processing technology process 1. Forging and hot forging are still widely used blank forging processes for automotive gear parts. In recent years, cross wedge rolling technology has been widely promoted in shaft machining. This technology is particularly suitable for making complex stepped shaft blanks. It not only has high precision and small post-processing allowance, but also has high production efficiency.

The gear module is the most basic parameter for modular gear teeth, and the modules of spur, helical, and bevel gears can all refer to the standard module series table. If the number of teeth of the gear is constant, the radial size of the wheel will also be larger. The modular series standards are formulated based on design, manufacturing, and inspection requirements. For gears with non straight teeth, there are differences in modulus between normal modulus mn, end face modulus ms, and axial modulus mx, all of which are measured in millimeters based on the ratio of their respective tooth pitch (normal pitch, end face pitch, and axial pitch) to pi. For bevel gears, the module can be divided into large end module me, average module mm, and small end module m1. For cutting tools, there are corresponding tool module mo, etc. The application of standard modulus is very wide. In metric gear transmission, worm gear transmission, synchronous toothed belt transmission, ratchet, gear coupling, spline and other parts, standard modulus is the most basic parameter. It plays a fundamental role in the design, manufacturing, and maintenance of the above-mentioned components (see cylindrical gear transmission, worm gear transmission, etc.).
