Worm Gear Units 2014

Product catalog summary

Overview

This technical document details worm gear units and worm reducers, covering various centre distances, materials, manufacturing capabilities, and performance data. It includes specifications for standard worm gear sets and molded units, as well as options for customization.

1. Product Range and Centre Distances

Worm Gear Units: Available with centre distances of 50 mm, 63 mm, 80 mm, 100 mm, and 125 mm.
Worm Reducers: Designed primarily for manual operation.
Moulded Worm Gear Units: Manufactured from polyamide and zinc injection molding for specific applications.

2. Manufacturing Capabilities

Custom manufacturing of components including bored worms, worm shafts, worm wheels, and complete reducers.
Milling capabilities up to 275 mm diameter (module 1.6 to 10).
Grinding capabilities up to 250 mm diameter (module 1 to 10).
Ready-to-install components with bore and keyways per DIN standards or customer drawings.
Options for extended shafts, motor flanges, motors, and couplings.

3. Materials and Standards

Worm Shafts: Steel 1.7131 (16 MnCr 5), available hardened and ground or non-hardened/non-ground.
Worm Wheels: Special bronze CuSn 12 with steel hub or cast iron EN-GJL-250 (DIN EN 1561).
Bored Worms: Steel 1.0503 (C45) with keyways per DIN 6885.
Right-hand gearing according to DIN 3975/3976.

4. Technical Specifications and Performance Data

Extensive tabulated data includes:

Gear ratios from approximately 7.25:1 to 83:1.
Module sizes ranging from 1 to 5.
Number of teeth and threads, pitch diameters (dm, da, dn), widths, lengths, bore diameters, and weights.
Part numbers for hardened/ground and non-hardened/non-ground variants.
Performance parameters such as input speeds, starting torque, input power, output torque, and tooth efficiency.

Data assumes uniform, shock-free operation with lubrication using Klübersynth UH1 6-460 grease. Default application and safety factors are 1.0 but should be adjusted per operating conditions.

5. Design and Application Notes

Worm shafts feature soft extension shafts customizable by machining.
Worm wheels use high-quality special bronze for superior sliding properties; cast iron is used for less demanding applications.
Transmission power calculations should consider operating, safety, position, and intermittent operation factors to select appropriate gear size.

6. Worm Gear Units for Manual Operation

Simple worm reducer available with 30:1 gear ratio, 20 Nm output torque, 1.5 kg weight, and grease lubrication.
Worm wheel made of special bronze; worm made of steel.
Custom solutions available upon request.

7. Recommendations and Customer Support

Consult engineering department for non-standard dimensions or special requirements.
Specify bore and keyway details per DIN or provide custom drawings.
Consider material and heat treatment options based on load and environment.
Use provided part numbers and technical data for accurate ordering and integration.
Manufacturer emphasizes flexibility and customer-oriented solutions.

Summary of Key Points

Wide product range with multiple centre distances and gear ratios.
Comprehensive manufacturing capabilities including milling, grinding, and ready-to-install parts.
Use of high-quality materials compliant with DIN standards.
Detailed technical and performance data for precise product selection.
Availability of customized solutions and engineering support.
