Gear spindle refers to the shaft on a machine tool that drives the rotation of a workpiece or tool. Usually composed of spindle components, bearings, and transmission components (gears or pulleys). In machines, it is mainly used to support transmission components such as gears and pulleys, transmit motion and torque, such as machine tool spindles; Some are used to clamp workpieces, such as mandrels. The gear spindle box is an important component of the machine tool, which is used to arrange the working spindle, its transmission parts, and corresponding additional mechanisms of the machine tool. The spindle box is a complex transmission component, including spindle components, reversing mechanisms, transmission mechanisms, braking devices, control mechanisms, and lubrication devices. Its main function is to support the spindle and rotate it, achieving functions such as spindle start, brake, speed change, and direction change.

Gearbox is an important mechanical component widely used in wind turbines. Its main function is to transfer 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, far from reaching the required speed for the generator to generate electricity. It must be achieved through the increasing speed effect of the gearbox gear pair, so the gearbox is also called the increasing speed box. According to the modular design principle of unit structure, the number of component types is greatly reduced, making it suitable for large-scale production and flexible selection. The spiral bevel gear and helical gear of the reducer are both carburized and quenched with high-quality alloy steel, with a tooth surface hardness of up to 60 ± 2HRC and a tooth surface grinding accuracy of up to 5-6 levels.
