Altra Industrial Motion 2000 Series Taper Grid Resilient ouplings for Protection from Shock, Misalignment and Vibration
2000 Series Taper Grid Resilient ouplings Bibby Taper Grid Resilient ouplings Dr. ames Bibby originally invented the Resilient oupling in 97 and the 2000 series is the latest development of this well accepted product. This Bibby Transmissions product has become universally accepted where reliable protection against shaft misalignment, vibration and shock is desirable. Since those early days refi nements in design and material specifi cations have kept pace with advancing technology, achieving signifi cant improvements in power/weight ratios. Principles Positive protection against the damaging effects of shock loads, impact loads and vibration. The Series 2000 is torsionally fl exible. The circumferential fl exibility is progressive due to the curved profi le of the grooves state-of-the-art in resilient coupling design. Light load Normal load Shock load Accoodating Shaft Misalignment and End-Float The Series 2000 will accoodate combinations of misalignment present at set-up or occurring during machine displacement, settlement, etc. Limited End-Float kits are available on request.

In these instances axial restraint of the hub should be provided by set screws. Relative sizes and positions are given in the table at the left. For sizes above 2090T or where interference fi ts are preferred for smaller coupling sizes, bore tolerances should provide an interference fi t between shaft and hub of 0.0002 to 0.0007 per of diameter. M0 X 0 2090 = 72 Versatile Design Both 2000H and 2000V couplings feature identical hubs and grid springs, the different cover styles endowing the units with great versatility - one is horizontally split, the other is vertically split. All coupling components are designed to be interchangeable with other taper grid couplings. Easy Installation and Maintenance The grid springs are easily installed by hand or with a soft mallet. The cover fasteners can be tightened with standard wrenches. Every Bibby Transmissions Series 2000 coupling is delivered with detailed installation instructions. Periodic lubrication of the coupling is required and each cover half is supplied with standard plugs which can be easily removed for re-lubrication. Extended lubrication periods and enhanced coupling life can be achieved by using high performance lubricants referred to in the maintenance instructions.

Applications like Reciprocating ompressors with frequent torque reversals, which do not necessarily cause reverse rotations Table 2 Number of ylinders onsult Bibby Transmissions Service Factor 6 and over 0.5 + S.F. Table 4 or less.0 + S.F. Table Less than 4 refer to Bibby Transmissions The system peak torque is the maximum load created by the driving or driven equipment. Occasional peak torques of twice the catalog rating can be accoodated providing they occur less than 000 times during the life of the coupling. For drives where the operation is near or actually passes through a major torsional natural frequency, a mass elastic analysis of the system is advised. When the Service Factor in Table is greater than 2, consult your supplier or Bibby Transmissions.
