Article

Eddy-current couplings (coupling/clutch/brake), while slowly being replaced by variable-frequency drive (VFD) technology, are still in use and will require repairs. As these devices become less common, the expertise pool is also shrinking. On the positive side, their specialized nature ensures that those familiar with these units will be in demand for some time.

Limiting end float of a sleeve bearing machine

  • April 2019
  • Number of views: 7362
  • Article rating: No rating
Article

There are applications where the end float inherent to a sleeve bearing machine is not desirable, and some means of limiting the axial movement is needed. This is usually accomplished by selecting an appropriate coupling and relying on the driven equipment to prevent axial movement of the motor shaft. 

The gear-hub style of coupling can be end-float limited by installing a “hockey-puck” spacer. The grid-style coupling can be limited by spacers inserted on both sides. 

Regardless of coupling style, unless the driven equipment has some internal means to limit end float, there are circumstances where some external means of preventing axial movement is needed.

Article

Proper alignment of direct-coupled machinery is an essential element in reliability of a new or repaired machine (motor, pump, gear case, etc.). One common impediment to achieving proper alignment and smooth operation is a “soft foot” condition. This article looks at detecting soft foot, correcting soft foot and general recommendations for shims.
