Reducers and Variators
Gearmotors, reducers and speed variators are used in all industry sectors. In fact, they are used in the most diversified application fields:
- security access;
- food;
- glass ceramic;
- industrial appliances;
- machine tools.
Energy consumption and vibration reduction
A product designed for low energy consumption must necessarily guarantee high silence together with low production of vibrations: these represent energy losses that are no longer acceptable (in an increasingly competitive market).
Accuracy of the work performed
Furthermore, it is necessary to guarantee a high reliability and precision of the work performed. In this sense, the choice of the Radial Clearance is relevant, starting from the Standard ones (Normal, C2 and C3) and also Customized Radial Range.
Types of Applied Loads
Radial Load (DGBB), Axial Load (ACBB) and Combined Load (TRB) solutions are available. Depending on the size of the loads, it’s also possible to have customized solutions, acting on: steel quality, number and balls size for DGBB and ACBB, number and rollers size for TRB.
Key requirements
1. Study and verification of the coupling and assembly requirements;
2. Super pure 100Cr6 steel to increase bearing life;
3. Fine grinding to obtain P5 or P4 tolerances on the raceways;
4. Super-finishing to reduce surface roughness;
5. G10 grade balls to reduce friction;
6. Ultrasonic cleaning combined with demagnetization treatment;
7. 100% control of noise and vibration along the production line;
8. Different seal configuration: no contact, light contact, heavy contact (with one or more lips);
Our challenges
1. Application requirements
- Mounting specifications;
- High RPM;
- Noise and Vibrations;
2. Control Standards Implemented
- Automatic production line;
- Dedicated control grids;
