Specifications and Requirements
The document outlines specifications for gear unit selection, focusing on power ratings and operational conditions. It emphasizes determining the nominal power rating (P2N) and ensuring power fractions (PI, PII, etc.) meet specific criteria: each must be greater than 0.4 x P2N and not exceed 1.4 x P2N. If any power fraction exceeds P2N, their cumulative time fractions must not surpass 10%. Additionally, peak power not considered in P2äq calculations should not exceed 2 x P2N.

Procedures
The gear unit design process involves selecting the type and size based on the transmission ratio and checking the starting torque. Guidelines are provided for calculating the equivalent power rating for machines with constant speed and variable power, using a service classification cycle.

Standards and Norms
Key factors for gear unit selection include ambient temperature, installation conditions, and the need for auxiliary cooling. Gear units should be equipped with appropriate cooling systems, such as fans or cooling coils, depending on operational conditions.

Recommendations
For gear units like the PB53-SH with a nominal ratio of 45, auxiliary cooling is recommended. The document advises consulting with NRW for variations in oil type, viscosity, and cooling systems. It also highlights the importance of recalculating assumptions if operational conditions deviate.

Key Data and Calculations
The document includes detailed calculations for determining thermal capacity (Pt) and the necessity of auxiliary cooling. It provides formulas and factors (f1, f2, etc.) for calculating mechanical power ratings and thermal capacities, with references to specific tables for detailed values.

Specifications
1. Operating Conditions: The document specifies values applicable under two main conditions:
- Condition A: 100% operating cycle in a large hall with an altitude up to 1000 meters.
- Condition B: Cooling water inlet temperature of 20°C with no limit on the outlet temperature. Recalculation with a limited outlet temperature is possible upon request.

2. Gear Units: The document categorizes gear units into four types based on cooling mechanisms:
- Pt1: Gear units without auxiliary cooling.
- Pt2: Gear units with fan cooling.
- Pt3: Gear units with built-in cooling coil.
- Pt4: Gear units with fan and built-in cooling coil.

Procedures
- Recalculation of cooling water outlet temperature is available upon request.
- Forced lubrication is required for horizontal gear units.

Norms and Recommendations
- The document emphasizes the importance of maintaining specified cooling water temperatures and operating conditions to ensure optimal performance.

Data Summary
- The document includes extensive tables detailing nominal power ratings (P2N) and thermal capacities (Pt) for various gear unit sizes and configurations.
- Key data points include power ratings and torque values for different gear unit sizes, indicating their capacity and performance under specified conditions.

Critical Information
- The document highlights the necessity of adhering to specified operating conditions and cooling requirements to maintain gear unit performance and longevity.
- It also notes that certain calculations and configurations are available only upon request, indicating the need for customization based on specific operational needs.

Specifications
Shafts are specified with tolerances of m6 for diameters ≤Ø100 and n6 for diameters >Ø100. Keyways are according to DIN 6885/1, with hub keyway width following ISO JS9 standards. Parallel keys conform to DIN 6885/1 form B. Detailed specifications can be found on pages 127-136.

Cooling Coil
Designs A, C, and E do not support forced lubrication via a flanged-on pump. However, forced lubrication with a motor pump is available upon request. The cooling coil is suitable for fresh, sea, and brackish water, with a maximum cooling water pressure of 8 bar.

Space Requirements
For pump pipes and cover, exact dimensions should be confirmed with the manufacturer.

Design Variants
For shaft-mounted gear units, designs A, D, and G are available on request. Approximate values are provided, with exact data available in order-related documentation.

Lubrication
Dip lubrication and forced lubrication options are available, with specific configurations depending on the design variant.

Dimensions and Weight
Dimensions are provided in millimeters, with weight and oil quantity specified for different sizes and configurations. The document includes detailed tables for various shaft types and configurations, such as solid shafts, hollow shafts for shrink disks, and flanged shafts.

Additional Notes
All gear units are provided without oil filling, and specific configurations may require consultation with the manufacturer for precise measurements and compatibility.

Overview This document provides technical specifications and guidelines for motor bell housings compatible with IEC standard motors, focusing on B and N couplings. It includes detailed tables of dimensions, sizes, and ratios for various motor and coupling configurations.

Specifications The document lists various motor sizes and their corresponding dimensions, including diameter, length, and height measurements. It specifies the compatibility of motor sizes with different coupling types, such as B and N couplings, and provides detailed fitting dimensions according to DIN 42677 standards.

Procedures For plants with special design requirements, such as high switching frequency or alternating load directions, the document advises checking the coupling design against the valid coupling brochure. It also suggests consulting NRW for non-standard couplings.

Standards and Norms The document references IEC standards and DIN 42677 for motor fitting dimensions. It emphasizes the importance of adhering to these standards for ensuring compatibility and performance.

Recommendations For specific applications like hoisting gears or traveling gears, the document recommends verifying the coupling design with the respective catalog. It also advises consulting NRW for any deviations from standard couplings.

Tables and Data The document includes several tables (e.g., Table 6, Table 7, Table 8) that provide detailed data on motor sizes, coupling dimensions, and ratios. These tables are crucial for selecting the appropriate motor and coupling configuration for specific applications.

Critical Information Key parameters such as motor size, coupling type, and fitting dimensions are highlighted. The document also notes limitations, such as the non-compatibility of certain designs with Taconite E or labyrinth seals on input shafts.

Cooling Options
The document discusses two cooling options for gear units: a fan and a cooling coil. The fan is attached to the input shaft and is effective at speeds above 900 min^-1. Below this speed, a cooling coil is recommended. The cooling coil requires a water supply with a maximum pressure of 8 bar, a flow rate of 5 l/min, and a maximum temperature of 20°C. These options enhance the thermal capacity of the system.

Heating Option
In very low ambient temperatures, pre-heating the lubricant may be necessary. This involves installing an electrical heating element with a thermostat to ensure the lubricant reaches the minimum temperature required for operation. The installer must provide the necessary wiring.

Lubrication Options
For continuous duty and vertical installations, a forced lubrication circuit with a pump is available. This ensures adequate lubrication of the top bearings but is not suitable for dual shaft configurations. For intermittent duty, a motor pump can be used, but it cannot be combined with the fan cooling option.

Gear Unit Types
The document outlines various types of gear units, including bevel-helical gear units with different housing designs (solid and split) and sizes. It provides details on mounting positions, output shaft designs, and additional specifications required for orders.

NRW Gear Units
NRW gear units are newly designed with more sizes and fewer parts, offering higher reliability and power capacity. They are available for horizontal installation with specific inclination allowances. The design includes noise reduction features and efficient thermal conduction, leading to increased operational reliability and reduced maintenance costs.

General Information
The document emphasizes the importance of adhering to safety regulations, proper oil filling, and using permitted lubricants. It also provides guidelines for installation, including foundation bolt specifications and corrosion protection measures.
