Worm Gear Units
Worm Gear Units
The installation of worm gear units requires stable fastening to prevent vibrations, checking the correct rotation direction, and protection from weather conditions. Long storage may necessitate seal replacement. Proper cooling and lubrication are essential, and specific mounting positions must be adhered to. A gradual start-up is recommended to avoid immediate maximum load application.
Performance specifications are based on specific mounting positions. Applications that could be hazardous, involve high inertia, or occur in extreme environments require consultation with technical services. The maximum torque should not exceed twice the nominal torque.
Reducers are supplied with either synthetic or mineral oil, depending on size. Regular oil level checks and replacements are necessary, especially for sizes 110-130. Special considerations are required for extreme temperatures, including the use of special oil seals and ensuring motors are suitable for low temperatures.
The service factor depends on load type, start-up frequency, and daily operating time. Load types are categorized as uniform, medium, or heavy, with specific applications listed for each. The moment of inertia should be considered, and technical service should be consulted if necessary.
Standard motor mounting positions are B3/A unless specified otherwise. For vertical placements, consult with technical services for critical applications. For non-standard positions, contact the Technical Service.
