Product catalog summary

Overview and Design Specifications

The document comprehensively details the R series gearboxes and drives, featuring cast iron monobloc housings in 12 sizes. Torque capacities range from 85 to 18,000 Nm, with power ratings up to 27,000 W. Input configurations include IEC flanges and solid shafts, with multiple mounting and assembly options to suit diverse applications.

Options and Variations

Available options encompass external fans, protective canopies, single-phase motors, and irreversibility mechanisms such as brakes. Variations allow customization of gearbox and motor components to meet specific operational requirements.

Service Factor and Load Characteristics

Service factors depend on the driven machine’s technical specifications and load types, classified as Uniform (U), Moderate (M), or Heavy (H). Heavy load applications require higher service factors. Operating time and start frequency influence fatigue and thus the service factor. An example illustrates selecting the appropriate service factor for a chain bucket excavator operating continuously under heavy load.

Radial and Overhung Load Calculations

The document provides procedures and tabulated data for calculating radial and overhung loads on output shafts, including fixed values for different gearbox series. These calculations ensure correct sizing and durability under various load conditions.

Brake Systems

Brake options include delayed action brakes (24V and 220V), sudden stop brakes, and light brakes. Details cover coil terminals, auxiliary contacts, and wiring requirements, including short-circuit cables, to support proper brake integration.

Mounting Positions and Terminal Box Locations

Standard mounting position is "KP1" unless otherwise specified. Cable entry is typically at position "A", and flange-mounted gearboxes are designated "V". These standards facilitate consistent installation and maintenance.

Lubrication and Oil Quantities

Oil volumes vary by mounting position and gearbox type. Symbols indicate oil filling, ventilation, oil level, and plugs. Tables specify oil quantities in liters for different configurations to ensure proper lubrication and prevent leaks.

Installation and Maintenance Recommendations

Verify oil levels and gearbox count before operation.
Ensure ventilation plugs are active to avoid pressure build-up and leaks.
Inspect and tighten bolts and screws after transport and installation to prevent vibration damage.
Change oil after the first 500 hours, then every 6000 hours.
Consult the user guide for technical issues and contact MAK technical support for emergencies.

Gearbox Coding and Options

Gearboxes are coded by number of poles (2, 4, 6, 8), body length (S, M, L), size (53, 63, 73, 83, 94, 153), input options (M, P, PM), and motor size (e.g., 71). This coding enables precise identification and ordering.

Corrosion Protection and Paint Specifications

Paint types include epoxy with zinc phosphate pigment and aliphatic acrylic polyurethane. Thickness ranges from 40 to 120 μm depending on environment (indoor/outdoor, humidity, chemical exposure), ensuring durability and corrosion resistance.

Quality and Compliance Certifications

ISO 9000:2008 Quality Management System
OHSAS 18001:2007 Occupational Health and Safety Management
CE Declaration of Conformity

Performance Tables

Extensive tables provide data on power, output speed, service factor, output torque, overload capacity, and transmission ratios for various gearbox types and sizes. Key parameters include:

Power ratings from approximately 100 W to over 27,000 W
Output speeds ranging from under 10 rpm to over 26,000 rpm
Service factors varying from 0.28 to over 3.5 depending on load and speed
Torque values aligned with power and speed for safe operation

Data Structure and Usage

The data is organized in multiple tables segmented by gearbox types, sizes, and operating conditions. Parameters include power (Potencia), output speed (Velocidad de salida), service factor (Factor de servicio), output torque (Par de salida), overloads (Sobrecargas), transmission ratio (Relación de transmisión), and type (Tipo). Numeric codes correspond to specific models or configurations.

Critical Observations and Recommendations

Select gearboxes based on required power, speed, torque, and service factor to ensure reliability.
Consider overload capacities for transient or peak load conditions.
Match transmission ratios to application speed and torque requirements.
Use type codes for precise ordering and specification.
Verify units and consult manufacturer documentation for installation and maintenance.

Limitations

The document provides raw numerical data without explicit units or procedural instructions. Interpretation requires domain knowledge and cross-reference with technical manuals. No diagrams or graphical elements are included.

Summary

This document is a comprehensive technical reference for R series gearboxes and drives, covering design specifications, options, load calculations, braking systems, mounting, lubrication, maintenance, corrosion protection, certifications, and detailed performance data. It supports engineers and technicians in selecting, installing, and operating gearboxes across diverse industrial applications, ensuring mechanical performance, safety, and durability.

Value of the service factor of a gearbox depends on all technical and characteristic specifications of a driven machine. Generally machines have three types of loading characteristics: El valor de factor de servicio de reductores depende técnica y características de una máquina accionada. En general, las máquinas tienen tres tipos de características de carga: UNIFORM LOAD (U) MODERATE LOAD (M) CARGA MODERADA (M) CARGA PESADA (H) Even if the torques required by three different machines operating at three different load specifications are equal. Las especificaciones de carga permanecen iguales...
