Application areas with wheels
Industrial Machinery: Such as conveyor belts, elevators, textile machinery, packaging machinery, lathes, forging and pressing machines, etc. Pulleys are used to transmit power and motion, coordinating the work between various components.

Main types of engineering machinery parts
Machined Components Definition: Components manufactured through machining processes, such as shafts, gears, and bearings. Applications: Power transmission, support of rotating components, such as drive shafts and gearbox gears. Characteristics: Requires high-precision machining, materials are mostly alloy steel or cast iron, directly affects mechanical transmission efficiency.
The core function of the motor shaft spiral
Screw Drive: Converts rotary motion into linear motion or adjusts component positions through a screw pair (screw and nut). For example, the lead screw of a lathe uses screw drive to move the tool post. Differential Screw: Two sections of thread on the same screw with the same direction of rotation but different pitches, which achieve minute displacement through the pitch difference (e.g., in a micrometer).
Basic structure and working principle of worm gear
As the larger gear in a crossed-axis gear pair, the worm wheel meshes with the worm (a spiral-like active component). Its pitch surface can be cylindrical, conical, or toroidal, commonly a cylindrical worm wheel. The worm wheel teeth envelop the worm, and the engagement is line contact, resulting in higher load-carrying capacity than point contact crossed-axis helical gear mechanisms.
