Coaxial gear reducers | Choosing the right gear reducer
Before buying a gear reducer, it’s important to take several factors into account. A gear reducer is used to adapt the characteristics (torque and speed) of the input and output axis of a mechanism. This is why you have to know the torque and rotation speed. It is therefore appropriate to ask yourself about the torque first and foremost. A reducer increases the torque of your motor and thus allows a receiving member to rotate under the impact of a new...

How to choose this product
coaxial-gear-reducer

An in-line reducer has coaxial input and output shafts. Any type of reducer, even those with perpendicular input and output shafts (worm, bevel, etc.), can be made coaxial by the addition of a transfer gear. However, planetary gear reducers are favored in applications requiring an in-line arrangement since they are coaxial by design.

Technologies

All varieties of gear reducer are possible: worm, bevel, planetary, helical, cylindrical, etc.

How to choose

Choice will depend on the speed and torque of both the input and output shafts. These data will determine the gear ratio.
