Planetary gearboxes

Product catalog summary

Functional Description
The document outlines the structure and operation of a planetary gearbox, which includes components such as a sun gear, planet gears, a planet carrier, and an outer gear. The input is delivered through the sun gear, and motion is transferred to the planet carrier via the planet gears. Multi-stage gearboxes are formed by connecting individual stages, and right-angle drive combinations can be achieved with Vogel spiral bevel gear units.

Technical Data
Specifications cover materials and designs for components like housing, shafts, and gears. Housing options include cast iron, spherulitic graphite iron, aluminum, and stainless steel. Shafts are made from materials such as C45 or 42 Cr Mo 4, with options for stainless steel or chromium plating. Gear parts are case-hardened and made from materials like 16 Mn Cr 5 or 17 Cr Ni Mo 6. Details on oil seals, bearings, lubrication, and surface treatments are also provided.

Available Types
The document lists various planetary gearbox types, including foot-mounted and flange-mounted designs, with output torques up to 26,000 Nm. Types include P, PF, MP, MPF, LP, LPF, MLP, and MLPF, each with unique design features.

Ratio Plan
The ratio plan details gear ratios for different stages of planetary gearboxes, ranging from single-stage to three-stage configurations, with mathematically exact ratios depending on the gearbox type.

Usage Conditions and Size Selection
Guidelines are provided for calculating required input power based on shock factors and ambient temperature, explaining how to determine the appropriate gearbox size using calculated input power and output torque.

Maintenance, Lubrication, and Weight
Maintenance procedures, lubrication types, and gearbox weights are detailed, emphasizing adherence to guidelines for optimal performance.

Specifications
Detailed specifications for planetary gearboxes, specifically the MLPF 256 type, a 3-stage gearbox, include dimensions, motor flange types, and motor shaft dimensions.

Procedures
Motor mounting procedures are outlined for three versions (A, B, and C), each with specific instructions. Version A requires a motor shaft with a keyway for emergency stop torque transfer, Version B uses a profiled bush with a shrink disc, and Version C involves a shrink disc bush without a keyway, recommending motors with reduced shaft tolerance per DIN 42955 R standards.

Standards and Recommendations
For optimal performance, motors with reduced shaft tolerance and concentricity per DIN 42955 R standards are recommended. Necessary torque for tightening screws during assembly is specified to ensure secure connections.

Key Data from Tables
Tables detail permissible radial loads for different input and output speeds, motor flange dimensions, and motor shaft dimensions. For example, the permissible radial load for an output shaft of size 256 at 25 rpm is 100,000 N.

Critical Information
Emphasis is placed on using a keyway in the motor shaft for Version A to ensure torque transfer during emergency stops. The necessity of degreasing components before assembly and following the specified torque tightening sequence is highlighted to ensure proper assembly.

Specifications
Inertia values (kgcm²) for different gearbox types and sizes (P, PF, MP, MPF) across 1-stage, 2-stage, and 3-stage configurations are provided, indicating suitability for various applications.

Procedures
Details on input and output shaft dimensions for different gearbox types (P, PF, PH, PFH) and stages (1-stage, 2-stage, 3-stage) include shaft diameter, centring, key specifications, and thread depth.

Standards
DIN 6885 is referenced for keyway specifications, ensuring compatibility and standardization across applications.

Recommendations
Thermal power limits for industrial planetary gearboxes are specified, with conditions such as maximum input speed (2000 rpm), ambient temperature (20°C), housing temperature (90°C), and wind speed (1.25 m/sec) for optimal operation.

Contact Information
Contact details for Lenze distribution partners across various regions, including Germany, Australia, Austria, Belgium, Brazil, China, Czech Republic, Denmark, Finland, France, Hungary, India, Iran, Israel, Italy, and Korea, are provided for customer support and inquiries.

Das einfache Planetengetriebe setzt sich aus den koaxial angeordneten Bauteilen, Sonnenritzel, Planetenträger und Hohlrad, sowie den auf konstanten Achsabstand im Planetenträger drehbar angeordneten Planetenrädern zusammen. Der Eintrieb erfolgt über das Sonnenritzel. Über die Planetenräder wird die Drehbewegung auf den Planetenträger (Abtriebswelle) übertragen. Durch das Abwälzen der Planetenräder im Hohlrad erfolgt eine entsprechende Übersetzung.
