Common standard mechanical parts are roughly divided into:
Transmission parts (gears, sprockets, couplings)
Support and positioning parts (pins, sliders, bolts, washers)
Buffer/Damping parts (springs, dampers, buffer blocks)
Connecting parts (keys, splines, chains)
Auxiliary parts (rollers, adjustment screws, circlips)
Comprehensive List of Common Mechanical Standard Parts
| Type | Function | Common Standard Parts | Usage / Example | Description |
|---|---|---|---|---|
| Transmission Parts | Transmit rotational motion and torque | Gear | Spur gear, helical gear, bevel gear, worm gear | Rotational transmission, change speed/torque direction |
| Sprocket / Pulley | Sprocket, timing pulley | Used with chain/belt transmission | ||
| Coupling | Flexible coupling, diaphragm coupling | Connect two shafts, transmit torque | ||
| Universal Joint / Cross Shaft | Universal joint, cross shaft | Change rotation direction | ||
| Support & Positioning Parts | Support rotational or linear motion | Bearing | Ball bearing, roller bearing, plain bearing | Support rotating shaft, reduce friction |
| Slider / Rail | Slide rail, linear slider | Support linear motion, precise guidance | ||
| Pin / Pin Shaft | Cylindrical pin, tapered pin | Positioning, support rotating or sliding parts | ||
| Bolt / Nut | Hex bolt, flange nut | Fasten parts | ||
| Washer / Spring Washer | Flat washer, spring washer | Adjust gap, prevent loosening | ||
| Buffer / Damping Parts | Control motion or absorb impact | Buffer Block | Rubber buffer, polyurethane buffer | Absorb impact, limit travel |
| Damper | Pneumatic damper, hydraulic damper, rotary damper | Control motion speed, slow movement | ||
| Spring | Compression spring, tension spring, torsion spring | Provide force, reset, or absorb energy | ||
| Connecting Parts | Fix or transmit torque | Key / Keyway | Flat key, half-round key, wedge key | Fix wheel to shaft, transmit torque |
| Spline / Internal-External Spline Sleeve | Spline shaft, spline sleeve | High torque transmission | ||
| Chain / Belt | Roller chain, timing belt | Transmit mechanical motion | ||
| Auxiliary Parts | Assist positioning or movement | Roller / Ball Guide | Ball pulley, roller bearing | Reduce friction, guide sliding |
| Adjustment Screw | Ejector screw, fine adjustment screw | Fine-tune position or tension | ||
| Locking Device | Set screw, circlip, retaining ring | Fix rotating or moving parts |
