bruntons sigmadrive - stops noise and vibrations

bruntons sigmadrive - stops noise and vibrations

The compact shaft coupling solution. SigmaDrive is a low maintenance, high torque, bearing free solution that stops noise and vibration. SigmaDrives can cope with a 3 degree misalignment of the shaft in any direction; 6 degrees in total and, unlike most CV shafts, the DS intermediate shaft coupling can be fitted inline or at an angle making installation much easier and faster.

Even if an engine and propeller shaft are perfectly aligned when the vessel is built, maintaining that alignment when the engine is running and the vessel moving is an impossibility. However well the boat is built, that allows noise and vibration to be generated. SigmaDrive anti-noise and vibration solutions are available for virtually every type of craft with engines up to 1300hp.

Other attempts at solving these solutions rely on rubber couplings or Carden units. The SigmaDrive requires none of these, is compact and easy to fit, usually without slipping the vessel or requiring modifications to the shaft line. It s a premium product manufactured from a special bronze alloy that is maintenance free and its internal components are hard wearing and long lived.

We come across similar problems regularly in the equipment having fluid couplings. In case of conveyor systems, we are able to identify the source of unbalance (turbine side or pump side) using high resolution spectrum. However, during balancing the phase of 1X amplitude keeps changing every second. What do you suggest in order to get the location of balance correction mass if phase in changing to a vast extent rapidly?

Hi Kumar, Unfortunately you have very little control over the phase change.The change in phase is as a result of the beat taking place between the interacting 1x from turbine and pump. Proceed with the balance job within a fairly stable phase to trim to a best possible level.You may manually control and accept the data if using CSI 2140 data collector.

Having encountered various problems related to unbalance of conveyor drives, I can totally relate to the case studies shown. But the major issue we find during the balancing of the system is that phase angle of 1X vibration keep on changing vastly and rapidly. High resolution spectrum does help to identify which side is having greater unbalance (turbine or pump). But what do you suggest if we arent able to determine the phase angle?

Hi Kumar, do not use the angular division method, rather use discrete if your data collector support that.In that case your focus is on the radial locations or positions. The phase should not be perfectly stable you know due to beating phenomenon.

R+W drive components are an essential part of just about any high performance machine - from the latest high tech medical devices to wind turbines and drilling platforms to space systems. Couplings are used wherever rotation and torque need to be transmitted between two machine components. The requirements placed on couplings differ greatly along the lines of their areas of application. Aside from reliable torque transmission, their most important tasks include providing protection against damage from shaft misalignment, vibration and torque overload. For high performance machinery to run with speed, accuracy and efficiency, torque transmission needs to be fast, precise and reliable. To this end, R+W can perfectly tailor critical performance characteristics of its couplings, such as damping, torsional stiffness, balancing, and moment inertia.

Coupling selection is always dependent on the application and its unique requirements. R+W offers various coupling models for both high precision and heavy industrial machinery types. Precision couplings transmit torques ranging from 0.05 to 25,000 Nm, depending on the coupling type and size. R+W's product range includes torsionally rigid metal bellows and miniature bellows couplings, vibration damping elastomer couplings, torque limiting safety couplings, connecting shafts, and servo disc pack couplings in a wide variety of sizes and configurations. Industrial series couplings transmit torques ranging from 200 to 2,080,000 Nm. Here R+W offers heavy duty safety couplings, torsionally rigid disc pack couplings and flexible gear couplings, along with larger sizes of metal bellows couplings and elastomer couplings. No matter how widely the challenges for a coupling and its function may vary - R+W is the pioneer in coupling technology and provides solutions for all industries.

Whether for high precision or heavy industry, couplings from R+W work dynamically, precisely and with zero backlash. They help to keep friction to a minimum, and many are wear and maintenance free, with no moving parts - thus guaranteeing an extremely long service and performance life. Through its wide product portfolio and innovative coupling technology, R+W is ready to meet your torque transmission challenges.
