ZDY Single Stage Gear Reducer for Belt Conveyor | Industrial Gearbox Case Study
H1:ZDY Single-Stage Hardened Cylindrical Gear Reducer Case Study – Belt Conveyor Drive System
ZDY series single-stage parallel shaft hardened helical gear reducer is widely used for low reduction ratio, continuous-duty industrial drive. Its compact layout and high transmission efficiency make it an ideal drive solution for belt conveyors in bulk material handling.

H2: Customer Background
A Southeast Asian automation equipment OEM specializes in bulk material conveying systems for grain and chemical plants. The customer’s fixed belt conveyor runs 24 hours a day with steady medium-heavy load. Their previous ordinary reducer suffered from excessive temperature rise and frequent oil leakage, leading to unplanned shutdowns and production losses.
H2: Tooth Surface Cylindrical Reducer Technology Challenge
Non-stop S1 continuous operation all day long
Limited installation space, requiring compact drive unit
Stable output speed, low running noise
Reduce regular maintenance and downtime
H2: Our Selection Solution
Our engineering team recommended the ZDY single-stage hardened cylindrical helical gear reducer after service factor calculation.
Model: ZDY200
Reduction Ratio: 3.15
Gear: Carburized & precision ground, HRC 58–62
Housing: Reinforced cast iron
Lubrication: Splash lubrication, standard oil seal design
Service factor: 1.25
H2: ZDY single-stage helical gearbox On Site Operation Result
After installation and 6-month continuous field test:
Transmission efficiency reaches up to 97%, saving power consumption
Full-load temperature rise controlled below 40K
No oil leakage observed in long-term running
Unplanned downtime reduced by 42%
Easy access to spare parts for later maintenance
H2: Technical Reminder
ZDY single-stage reducer is designed for small reduction ratio scenarios. If your conveyor system needs a larger ratio, ZLY two-stage or ZSY three-stage gearbox will be the alternative solution. We provide service factor calculation and drawing review for your equipment design.
H2: Inquiry & Custom Solution
If you need 2D drawings, 3D files, ratio selection support or quotation of ZDY gear reducer for belt conveyor projects, please submit your working conditions: motor power, input speed, required ratio, load type and installation form. Our mechanical team will reply within 24 working hours.
