Toothed Clutches and Brakes

Product catalog summary

Overview

This document details the technical specifications, mechanical dimensions, and operational characteristics of SG Transmission's electromagnetic tooth clutches, including variants with bearings and sliprings. It covers multiple product series designed for a wide range of torque capacities and application requirements.

1. Product Components and Terminology

The clutches consist of key components such as the rotor (rotating part), armature (engagement element), coil body (housing the electromagnetic coil), springs (for engagement/disengagement force in some models), pins (fasteners), adaptor plates/flanges (mounting interfaces), brackets (support structures), and sliprings (for electrical connection in slipring variants).

2. Electrical and Mechanical Specifications

Nominal Voltage: Primarily 24 V DC, with some models supporting up to 96 V.
Input Power: Ranges from approximately 12 W to 5500 W depending on model and torque rating.
Torque Range: From 20 Nm up to 18,000 Nm across different series.
Engagement Times: Typically between 18 ms and 140 ms.
Disengagement Times: Range from 50 ms up to 1350 ms, depending on clutch type.
Maximum Speed: Dry operation speeds up to 2200 rpm; oil-lubricated speeds can reach up to 6000 rpm depending on model.
Weight: Varies from 0.25 kg for small adaptor plates to over 55 kg for large clutch assemblies.

3. Product Series and Characteristics

VZDZS Series: Electromagnetic tooth clutches with bearings, torque ratings from 100 Nm to 6000 Nm, featuring trapezoidal or triangular tooth profiles with sawtooth orientations.
VZDZ Series: Similar to VZDZS but with a broader torque range (20 Nm to 18,000 Nm) and detailed rpm ratings for dry and oil conditions.
Adaptor Plates (FA, F, PD, P Series): Various mounting plates with specified dimensions, hole counts, and weights compatible with different clutch models.
FTDZS Series: Electromagnetic tooth clutches with sliprings, torque from 30 Nm to 8000 Nm, including detailed mechanical and electrical data.
FTDZN Series: Electrically released tooth clutches with sliprings and spring application, torque from 30 Nm to 950 Nm, designed for fail-safe disengagement.

4. Mechanical Dimensions and Mounting Details

Comprehensive dimensional tables specify parameters such as tooth count and form, keyway dimensions (per DIN 6885 standard), mounting hole sizes and counts, and overall clutch dimensions (parameters labeled A through T). These ensure proper mechanical integration and compatibility with shafts and mounting hardware.

5. Operational Recommendations and Limitations

Maintain nominal voltage at 24 V DC to ensure optimal clutch performance.
Observe maximum rpm ratings for dry and oil-lubricated conditions to avoid premature wear.
Consider engagement and disengagement times in timing-sensitive applications.
Use spring-applied models (FTDZN) for fail-safe operation where clutch disengagement upon power loss is critical.
Select appropriate adaptor plates and keys to guarantee secure mounting and effective torque transmission.

6. Additional Notes

The document includes multilingual terminology (Italian, English, Portuguese) to support international use and references standards such as DIN 6885 for keyways. Contact information for SG Transmission is provided for technical support.

Summary

This technical reference comprehensively supports the selection, specification, and integration of SG Transmission electromagnetic tooth clutches across diverse torque and application needs. It emphasizes critical mechanical dimensions, electrical characteristics, and operational parameters to facilitate design, installation, and maintenance.
