The goals of gearbox design in different usage environments are also different

The gearbox is an important part of the fan, and its main function is to accelerate the rotation of the rotor shaft to drive the generator to generate electricity. In addition to the transmission components, the gearbox also includes a detection system, a lubrication system, a control system, a heating system, a cooling system, etc.

Gearbox design goals:

The goals pursued by the development and design of gearbox products in different environments are also different, which can be roughly divided into:

High-power heavy-duty gearbox: the design goal is high reliability and long life. Typical examples are wind power generation speed-up gearboxes, hot rolling main drive gearboxes, vertical mill gearboxes, etc.

Gearboxes for vehicles and ships: The design goals are small size, light weight, and flexible and smooth operation when shifting gears are required. Typical examples are construction machinery gearboxes, vehicle travel gearboxes, and marine propulsion gearboxes.

High-precision gearbox: the design goal is small output speed fluctuation, small hysteresis, small vibration, etc. Typical examples are servo transmission gearboxes, foil strip finishing mill gearboxes, CNC machine tool transmission gearboxes, etc. -- motor driver

General-purpose gearbox: the design goal is modularization, high degree of serialization and standardization, good interchangeability, and moderate price.

High-speed gearbox: The design goal is smooth transmission, low vibration and noise, and good dynamic performance. Typical examples are steam turbine gearboxes, high-speed wire mill gearboxes, etc.

On-load starting gearbox: the design goal is controllable output speed or torque, and strong overload capacity. Typical examples are belt conveyor gearboxes, crane hoist gearboxes, mixer gearboxes, etc.

General-purpose gearbox: the design goal is low cost and low precision. Typical examples are agricultural machinery gearboxes, manual gearboxes, etc.

In fact, for a specific gearbox product, its design goal may also have the above-mentioned multiple features at the same time. Naturally, its design requirements are more complicated, and specific problems need to be analyzed in order to solve them in a targeted manner. specific problem. Determine the goal pursued by gearbox development and design, which can help to establish the objective function of product optimization design, or the design elements and directions that should be focused on.
