Worm gearboxes, Helical worm gearboxes and geared motors
This document is a technical catalog from Carl Rehfuss GmbH+Co.KG, focusing on worm gearboxes, helical worm gearboxes, and geared motors. It includes detailed specifications, terms and conditions, and descriptions of various models and configurations.
Deliveries and services adhere to the company's terms and conditions. Claims must be submitted in writing within 8 days of receipt. Prices are ex-factory, excluding packaging, and are subject to change.
- Worm Gearboxes: These feature a high-performance, universal design with hardened worm shafts and centrifugally cast bronze worm wheels. They are noted for high efficiency, quiet operation, and long life. The gear housings are made from high-quality aluminum, providing torsional stiffness and noise dampening.
- Motors: Standard voltages are 230/400 V at 50 Hz. Single-phase motors are available with different starting torques for various applications, such as circular saws and compressors.
The document includes codes for different gearbox types and configurations, such as solid shaft or hollow shaft, and mounting options like basic or flange mounted.
Options include torque limiters and torque arms for specific applications.
All gearboxes and motors are lubricated for life and can be mounted in any position. Detailed tables provide power and dimensions for various models.
The document specifies various mounting positions for flange-mounted motors, including B3, B6, V5, B8, B7, and V6. The terminal box is typically positioned at A with cable entry at 1 unless otherwise specified. For brake motors, cable entry is limited to positions 1 or 2.
Proper drive selection requires understanding the operating conditions. The service factor (fB) is influenced by load type, average daily operating time, starts per hour, and ambient temperature. The service factor affects gearbox size selection but not motor power. Load classifications are divided into three categories based on mass acceleration factors: I (≤ 0.2), II (≤ 3), and III (≤ 10). For factors > 10, consultation is advised.
Permissible loads are approximate and refer to standard shafts. Combined axial and radial forces reduce the radial force (Fr) by the axial force (Fa). Transmission elements like couplings and pulleys require consideration of additional factors when calculating radial forces.
Self-locking depends on the worm's lead angle. Static self-locking occurs at approximately 4.5° and can be affected by external vibrations. Dynamic self-locking occurs at angles < 3.5°.
The document includes selection tables for worm geared motors, specifying power (kW), output speed (min-1), torque (Nm), and service factor (fB).
The document outlines the maximum output torque (Ma max.) and input power (Pe) for different motor frame sizes and speeds. It provides data for speeds ranging from 125 min-1 to 3000 min-1, with corresponding torque and power values.
For speeds not explicitly listed in the tables, the document explains how to interpolate the maximum torque values to determine the required input power. The formula provided is: Pe = (Ma * ne) / (9550 * i * η), where Ma is the torque, ne is the input speed, i is the gear ratio, and η is the efficiency.
The tables present detailed data for motor frame sizes 56 and 63, with various gear ratios (i) and speeds. Each table includes columns for speed (min-1), torque (Nm), power (kW), and efficiency (%). The data is organized to show how these parameters change with different configurations.
The document emphasizes the importance of using the correct torque and power values for specific motor configurations to ensure optimal performance. It also highlights the need for interpolation when dealing with intermediate speeds not directly covered in the tables.

Im Normalfall und wenn bei der Bestellung nichts anders angegeben, befindet sich der Klemmenkasten bei A, die Kabeleinfhrung bei 1. Wird eine davon abweichende Anordnung des Klemmenkastens bzw. der Kabelein-fhrung gewnscht, so ist dies bei der Bestellung anzugeben. Bei Bremsmotoren ist die Kabel-einfhrung nur bei 1 oder 2 m켶glich. Normally and unless otherwise specified, the terminal box is in pos. A, and the cable entry is in pos. 1. If other terminal box or cable entry positions are required, they are to be specified when ordering. With brake motors only cable entry positions 1 or 2 are possible....
