Flexible Roller Chain Couplings are composed of a double strand roller chain and two sprockets. Roller chain couplings have a torque capacity in excess of the torque normally transmitted by shafting which falls within the coupling bore range. Select the smallest coupling which will accommodate both shafts. For a revising operation, shock or pulsating loads, or other severe operating conditions, select the next larger coupling size.
A cover should be used to assure maximum service life, particularly if the coupling operates at high speeds or under moist or abrasive conditions. For proper lubrication, fill the space between the cover and the coupling with soft to medium consistency bearing grease.
- Press fit center-link plates and single pin connectors.
- Available in QD and Taper-Lock styles.
1. FCL flexible coupling is widely used for its compact design, easy installation, convenient maintenance, small size and light weight.
2. As long as the relative displacement between shafts are kept within the specified tolerance, couplings will operate the best function and have a longer working life.
3. It’s greatly demanded in medium and miner power transmission system driven by moter, such as speed reducer, hoist, compress, conveyor, spinning and weaving and ball mill.
4.To be plugged in axially,easy assembly,maintenance free Applicable from -40oC to+100℃ temperature can peak up to 120℃.
– Torque transmission with high torsional rigidity.
– Compensates for axial, radial and angular misalignments.
– Spacer for axial disassembly of the pump rotors without affecting the alignment of the shafts.
– Max temperature : up to + 240 ° C.
– The hubs are delivered with pilot hole.
The machining done by us is :
– H7 tolerance for bores.
– Standard keyway according to DIN 6885/1.
– Two pressure screws : one on key, the other at 120°.
The roller chain coupling is a flexible coupling of amazingly simple construction. It consists of a combination of one coupling chain and a pair of coupling sprockets. Flexible and strong, the SSPTP roller chain coupling is suitable for a wide range of coupling applications.
Cast Aluminium Covers
For more demanding applications, cast aluminium covers extend life of couplings by providing continuous lubrication and full protection from abrasive elements. The two halves fit around the coupling and connect by ‘Nyloc’ cap-head bolts. Neoprene seals are fitted to seal between sprocket hub and cover. These covers are fitted after coupling is fully installed on shafts.
