Project example:

This geared motor unit was implemented in close cooperation with a motor manufacturer in order to find a cost-effective solution for the customer as quickly as possible. The customer from the tool industry needed a compact, high-performance gear, which has the shortest possible axial length. A typical feature of SPN Schwaben Pr├Ązision Fritz Hopf GmbH is the adaptation of standard gears in order to develop a drive solution that is ideally suited to the application.

Planetary gear for dynamic positioning tasks

An RC 45 planetary gear unit from SPN was used as the basic technology. This gearbox is designed with a flange shaft, which is characterized by a low torsional backlash, high rigidity, high torque and radial forces as well as low running noise.

So ideal for dynamic positioning tasks, such as the application required by the customer in a confined space. The freedom from maintenance due to lifetime lubrication and the low energy consumption also make the RC45 the perfect basis for the customized solution of the customer.

How planetary gears work

The SPN experts adapted the transmission accordingly so that it can be connected to the engine without a special clamping unit. The gearbox is sealed directly on the motor shaft, which is specially processed for this.

Project result:

In just a few weeks, the customer received a system of gear and motor that was ideally tailored to his needs. Not only was the time factor taken into account, but a cost-effective solution could also be offered thanks to the use of standard technology.

Select, design and insert the gear correctly

Coupling parts between the engine and the transmission are eliminated

Since the coupling parts between the engine and the transmission are omitted, a small overall length is achieved. Thanks to the direct motor mounting, the SPN technicians developed a compact drive unit in a simple manner.

Technical specifications:

  • Total translation: i = 10: 1
  • Nominal output torque: 65 Nm
  • Backlash: less than 3 arcmin
  • maximum drive speed: 6000 min -1
  • Weight: 6.2 kg

User meeting mechatronic drive technology

The focus of the user meeting mechatronic drive technology is on the mechanical components of gears, clutches and brakes as well as their design, dimensioning and interaction in the overall mechatronic system.
