Method for model chose
Please understand the following at first in order to select the model of NMRV speed reducer properly:
- Loading condition.
- Speed scope or ratio in application.
- Working condition and environment.
- Installation space.
Define working condition Coefficient K1 and revise coefficient K2.
- Ensure machinery load types A, B, C according to table 1.
- Get the working condition coefficient K1 from diagram 1 according to turning time (hour/day) and start
frequency (time/hour).
- Inspect working condition and select coefficient K2 from table 2.
Table 1 Machinery Load classification selection
| Using situation | Example | Load type |
| Uniform load | Convey band (uniform conveying) | A(Uniform load) |
| Moderate Load | Speed changed conveying | B(Moderate load) |
| Severe Load | Compressor, pulverizer, etc | C(Severe load) |
Table 2 Working condition coefficient K2
| Ambient temperature | Working condtion coefficient K2 |
| -10C~30C | 1 |
| 30C-40C | 1.1~1.2 |

Changzhou Welldone Transmission Machinery Co., Ltd. specializes in manufacturing various kinds of small and medium-sized equipment, Three phase asynchronous motor, such as DC motor, AC motor, reducer, planetary reducer, servo reducer, etc. We have professional gear tester (gear all-round inspection), Vickers hardness tester, Rockwell hardness tester (test hardness again to ensure wear resistance), radial runout detection (detect motor running in and balance, so that the motor can reduce wear and no noise during high-speed operation), withstand voltage tester (detect leakage, higher than normal voltage, no leakage), inter turn tester, surge test motor stator winding turn to turn insulation, thickened coil, same power torque output, torque is greater.
The "Welldone" gear reducer produced by our company sells well in provinces, municipalities and autonomous regions of the country. It is widely used in metallurgy, mining, lifting, transportation, petroleum, chemical, textile, pharmaceutical, food, light industry, grain, oil, feed and other industries, and is deeply trusted by customers.
Welcome new and old customers to visit and guide.
Q: How to select a suitable motor or gearbox?
A: If you have motor pictures or drawings to show us, or you have detailed specifications, such as, voltage, speed, torque, motor size, working mode of the motor, needed lifetime and noise level etc, please do not hesitate to let us know, then we can recommend suitable motor per your request accordingly.
Q: Do you have a customized service for your standard motors or gearboxes?
A: Yes, we can customize per your request for the voltage, speed, torque and shaft size.
Q: What's your lead time?
A: Generally speaking, our regular standard product will need 2-7days, a bit longer for customized products. It will depend on the specific orders.
