Overview and Product Description

The YP series speed reducers are engineered for heavy-duty, continuous operation applications such as conveyors and elevators. They utilize precision-ground helical gears made from 16MnCr5 steel hardened to 58 HRC. The cast iron housing is CNC machined to ensure noise-free, high-performance operation and precise dimensional accuracy. Multiple configurations are available, including hollow shaft, output shaft, flange mounting, and various installation options to facilitate assembly and maintenance.

Product Variants and Options

• YPM: IEC input flange with motor mounting.
• YP: Solid input shaft.
• Additional options include external fans, canopies, single-phase motors, irreversibility mechanisms, and torque arms (standard for geared motors without flange).

Service Factor and Load Characteristics

Service factors depend on the driven machine’s load type—classified as Uniform (U), Moderate (M), or Heavy (H) load—and operational parameters such as daily running time and number of starts. Heavy load applications require higher service factors to account for increased material fatigue. An example is given for a chain bucket excavator operating 24 hours under heavy load, illustrating the need for an elevated service factor.

Load Calculations

Methods and tables are provided to calculate overhung radial loads on output and hollow shafts, considering load application points relative to shaft midpoints. These calculations ensure correct gearbox sizing and durability under various load conditions.

Brake Options

Brake types include delayed action brakes (24V and 220V), sudden stop brakes (220V), coil terminals, auxiliary contacts, and wiring accessories such as short-circuit cables and transformers with rectifiers.

Mounting and Vibration Absorption

Special mounting options incorporate rubber rings acting as torque arms to resist shocks and absorb vibrations from the housing and output shaft, enhancing operational stability and extending service life.

Mounting Positions and Cable Entry

Mounting positions are designated with "V" for flange-mounted gearboxes. The standard mounting position is "KP1" and the default cable entry position is "A" unless otherwise specified.

Lubrication

A detailed lubricant table recommends mineral and synthetic oils with viscosity classes per DIN standards, specifying temperature ranges and brand examples (Mobilgea, Degol, Energol, Omala, Alpha, GEM, Klübersynth). Oil quantities vary by mounting position, with symbols indicating oil fill, ventilation, oil level, and plug locations.

Maintenance and Inspection

Maintenance guidelines stress verifying oil levels and quantities per MAK catalog, ensuring ventilation plugs function properly to prevent pressure buildup and gas leaks. Bolts and screws must be checked and tightened before startup to avoid vibration damage. Oil changes are recommended after the first 500 hours and subsequently every 6000 hours. For technical issues, users should consult the manual or contact MAK technical service centers.

Ordering Information

Ordering codes include motor pole numbers (2, 4, 6, 8), body length options (S, M, L), gearbox sizes (e.g., 53, 63, 73, 83, 94, 153), input options (M, P, PM), and motor reducer types (YP, YPF, YPP, YPFP). Additional options cover secondary motor reducer covers and types.

Performance Tables and Technical Data

The document contains extensive tabulated data detailing power ratings, gear ratios, output speeds, service factors, output torque, and overload capacities across various gearbox types and sizes. Key observations include:

• Output speed decreases as gear ratio increases, while output torque correspondingly increases.
• Service factors range from approximately 0.8 to over 6, reflecting different load intensities and safety margins.
• Overload capacities specify maximum permissible transient loads, critical for safety and durability.
• Speed ratings and type codes help identify suitable models for specific operational requirements.

Key Recommendations and Best Practices

• Select power, ratio, and speed parameters aligned with application needs, incorporating appropriate service factors to ensure reliability under varying loads.
• Respect overload capacity limits to maintain equipment longevity and safety.
• Match output speed and torque carefully to driven equipment requirements to avoid undersizing or oversizing.
• Use type/model codes for precise equipment identification and ordering.
• Consult additional documentation or manufacturer guidance for installation, maintenance, and compliance details.

Limitations

The document primarily provides raw numerical data without explicit procedural instructions, normative references, or graphical aids. Interpretation requires domain expertise in mechanical power transmission and familiarity with the equipment. Units for some parameters are not explicitly stated and should be confirmed via supplementary materials.

Summary

This technical document serves as a comprehensive reference for engineers and technicians involved in selecting, specifying, and maintaining mechanical power transmission equipment such as gearboxes and geared motors. It details critical performance parameters including power, speed, torque, service factors, and overload capacities across multiple configurations and operating conditions. The inclusion of product variants, mounting options, lubrication recommendations, maintenance guidelines, and certifications supports informed decision-making to ensure optimal performance, safety, and durability in industrial applications.
