简体中文 Core Parameter: How to lock in the direction of selection with numbers?
Load and accuracy are the first threshold for selection. When the single point load exceeds 60kg, it is necessary to change to chain or steel belt drive, and high precision scenes (such as electronic assembly) must choose the arc tooth synchronous belt, and the error needs to be controlled within 0.1mm. Light load scenes (<30kg) can choose economical T-type synchronous belt, heavy load (30-60kg) need HTD or GT type belt.
The golden formula for speed and power: The power calculation followsPd = K x Pt (K = 1.5 to 2.5)The HTD tooth shape must be selected for high speed line (>40m/s), and trapezoidal tooth can be used for low speed (<10m/s). Transmission ratio design needs to match the minimum number of teeth of the pulley (such as XL-type pulley ≥ 12 teeth), otherwise it is easy to jump teeth.
Scenario adaptation: how do different industries avoid the pitfalls?
Logistics and Warehousing ScenariosThe 500mm bandwidth can be adapted to carton conveying (item size 400×250×200mm), but need to reserve 10~15mm edge space to prevent falling. E-commerce sorting recommended power roller line, support right-angle turn and lift diversion.
Food Processing Pain Points: must be selectedPU or food grade PVC tapeThe line is made of neoprene rubber (CR) to avoid softening and deformation. High temperature baking line (>80℃) need to use neoprene (CR) material to avoid softening and deformation.
Manufacturing Heavy Duty Challenges: The preferred speed multiplier chain for automotive assembly lines, enablingPrecise positioning of variable speedsMining scenarios require wire rope core rubber belts with impact resistance upgraded by 300%.
The Balancing Act of Cost and Longevity
Installation Hidden Costs: Axis spacing formulaA=[L-π(D1+D2)/2]/2It is necessary to reserve 5% tensioning space, axis parallelism error > 0.5mm/m will accelerate the wear.
Maintenance cost control::
- Initial loaded tension calibrated by deflection method (non-contact tensiometer)
- Quarterly check for tooth wearSynchronous belt life is about 1~3 years
- Dusty environment with rotary brush cleaner, wear rate down 40%
Future trends: self-healing rubber coating extends life by 30%, graphene material rollers reduce resistance by 15%.
Selection is never a single-choice question, but a joint equation of parameters and scenarios. Neglecting a number can cost three times as much as maintenance; mismatching a scenario can cost half as much as efficiency. The bottleneck of your production line is often hidden in the uncalibrated tension and over-limit load.
