BEARING-MOUNTED CLUTCHES

Electromagnetic Single-disc Bearing-Mounted Clutches Type EDA


VORTEX ENGINEERING WORKS manufacture a wide range of Electromagnetic single-disc clutches and Brakes, which are intended for start-stop applications. They come in various types to meet different requirements.

Type EDA

The Bearing Mounted type EDA is "Normally Off " type clutch The bearing mounted stator consisting of a coil and rotor faced with friction material held to the stator by means of the bearing, and the armature plate. When current flows through the clutch coil, the armature plate is attracted to rotor with friction material, thereby transmitting the torque and is released immediately by a backlash-free sinusoidal wave spring, when current through the coil is off. These are used for dry applications only.

FEATURES

1. These bearing mounted clutches are specially designed for shaft mounting and centering is automatic.

2. The clutches are designed for simple mounting and easily adaptable to any mounting requirement as they are ....manufactured in varied designs.

3. The sinusoidal wave spring enables a backlash free transmission, enabling very short response time on ....disengagement. The friction faces are completely separated by the spring eliminating any drag and permitting use at ....very high idling speeds.

4. These units are practically maintenance free due to the stationery coil and highly wear resistant asbestos-free
....friction surfaces.

We have further versions to compliment our standard EDA series, which give higher flexibility in the mounting options to suite specific applications without compromising on the design of the other components and that of the end machine.
These include firstly the small micro clutch versions, series EDB (0.5 to 15 N-m) for low torque applications such as business machines, photocopiers, book finishing machinery, etc. These micro-clutches series EDB are actually an extension of the EDA series at the low end of the torque.

Also you will find details of our series of flexible clutches series EDC, which incorporate rubber elements for applications, which are susceptible to shocks during their actual operation. Example of this is shown below along with their mounting instructions.

MOUNTING INSTRUCTIONS
(For EDC series flexible clutches)
The radial and axial screws connecting the rubber element to the hubs must all be tightened using a torque wrench. Ensure that when tightening the screws the aluminium bushes do not twist in the rubber part and that they sit squarely. In order to reduce friction between the screw head and the aluminium bush smear a small amount of grease under the head of the screw before fitting.

If necessary, use a suitable tool to apply counter pressure on the element to prevent twisting of the rubber part while tightening the screws. This is particularly important with the radial screws otherwise the curved faces between the aluminium bush and the hub will not engage on the full area but only across the two sides . This will inevitably lead to slackening of the screws and destruction of the clutch. If the clutch is supplied in a preassembled state, do not dismantle it, but fit it in this condition.

We can also offer special steel-steel friction surface versions to complement these series for which you can contact our design team.
