Worm gear reducers - Technical catalogue - VSF/2012/REV.0
The document covers various models of worm geared motors and gear reducers, specifically the NMRV and NRV series. It emphasizes the modularity of these systems, which allows for different configurations and combinations tailored to specific applications.
The service factor is essential for selecting the appropriate gear reducer based on operating conditions. It takes into account the type of load (A - uniform, B - moderate shocks, C - heavy shocks), daily operating time, and start-up frequency. Guidelines for calculating the service factor are provided, and it is advised to consult technical services if the factor exceeds 10.
Performance specifications are based on standard mounting positions. For non-standard positions or specific input speeds, reference tables are available. Critical applications include avoiding use as a multiplier, high inertia applications, and environments with extreme temperatures or chemical exposure. The maximum torque should not exceed twice the nominal torque, and technical consultation is recommended for S3 service conditions.
It is advised to avoid applications involving partial immersion of the reducer, use in hazardous environments, or where failure could pose a risk to human safety. The document stresses the importance of consulting technical services for applications with high dynamic strain or in non-standard environments.
