1. Basic information: motor power / kw, output speed / rpm, speed ratio of reducer
2. Reducer form, is it a direct reducer of motor reducer or a separate reducer? Orthogonal axis, concentric axis, parallel axis or space orthogonal axis.
3.The output shaft is a solid shaft single key, a solid shaft spline, a hollow shaft single key, a hollow shaft spline, a hollow shaft lock disk or a solid shaft flange.
4. Is the reducer installed on the ground, flange, or moment arm?
5. What kind of equipment is used, how does it work, what is the load situation, whether it is long-term work, short-term work or intermittent work, light load or heavy load or shock load, which all feel the use factor of the reducer , Which is the safety factor, usually a safety factor of 1.2 6. Ambient temperature and working environment, whether there is dust, humidity, salt spray, etc.
7. The easiest way is to call the sales person of the reducer, they will help you get everything done.
