General Information:
The document includes general information about the gear units, emphasizing the importance of following safety and operational guidelines to ensure proper functioning and longevity of the equipment.

Specifications and Requirements:
The document outlines the requirements for power fractions and time fractions in gear unit design. The individual power fractions (PI, PII...Pn) must be greater than 0.4 x P2N and must not exceed 1.4 x P2N. If any power fractions exceed P2N, the sum of time fractions (XI, XII...Xn) must not exceed 10%. If these conditions are not met, P2äq must be recalculated. A brief peak power not included in P2äq calculation must not exceed Pmax = 2 x P2N.

Design Considerations:
For applications with variable torque but constant speed, gear units can be designed based on equivalent torque. A finite-life fatigue-resistant design may suffice for sporadic operations or low output speeds. For machines with constant speed and variable power, the gear unit can be designed based on equivalent power, calculated using a work cycle with phases requiring specific power levels and time fractions.

Gear Unit Selection:
The selection process involves determining the gear unit type and size, calculating the transmission ratio, and checking the starting torque. The nominal power rating (P2N) is selected from a power rating table. The gear unit design includes considerations for oil supply and cooling requirements, with options for auxiliary cooling such as fans or cooling coils.

Available as a commercial product and can be used in various designs and sizes.
For repairs, split shaft seals are recommended for flanged shaft designs.

Labyrinth Seals:

Ideal for higher operating speeds.
Non-contacting, wear-resistant, and maintenance-free due to no local heat development.
Require minimal space for installation.
Applicable only in stationary drives and should avoid extremely dusty environments.
Require horizontal shaft levels and specific lubrication methods.

Taconite Seals:

Provide high operational reliability in dusty environments.
Consist of a combination of three sealing elements to prevent dust ingress.

Installation and Design Considerations:

Noise Reduction:
To reduce noise levels in PGR gear reducers, conical gears are ground, and high-quality gears are processed using CNC programs. This ensures a broad contact surface, contributing to noise reduction.

Heat Conductivity:
PGR gear reducers are designed for high efficiency and suitable heat conductivity. The selection of reducers is based on the lowest maximum oil temperature, enhancing workplace safety and reducing maintenance costs due to longer lubrication intervals.

Storage and Design:
PGR gear reducers are designed with a modular system, reducing the number of different mounting parts. Most relevant parts are available in stock.

General Information and Safety:
Illustrations are examples and not binding. Dimensions and weights are subject to change. All rotating parts must be guarded according to safety regulations. Gear units are delivered ready for operation but without oil filling. Only permitted lubricants should be used, and the oil viscosity must match the data on the nameplate.

Selection Guidelines:
The document provides guidelines for selecting gear units, including determining the type and size, finding the transmission ratio, and checking maximum torque. It also covers the determination of oil supply and required thermal capacity. Gear unit sizes and reduction stages are provided in rating tables based on transmission ratio and nominal power.

Symbols and Calculations:
The document includes a key to symbols used in calculations and provides an example selection calculation for gear units, detailing the process of determining gear unit type, size, and nominal power rating.

Specifications and Components:
The document outlines the components of the PB...3-H series, including inner and outer bushings, a cage lock, and a friction lining. It emphasizes the importance of consulting for other arrangements and designs.

Torque Distribution and Backstop Functionality:
In systems with multiple drives, there is a risk of excessive restoring torque on a single gear unit. The torque-limiting backstop is designed to evenly distribute this torque across all gear units, reducing peak torques.

Backstop Arrangement:
The installation of the lock is dependent on the desired direction of rotation, as detailed on page 248.
