2011 was an exciting year in the history of Autogard. In April 2011, Autogard Holdings Limited were acquired by Rexnord Industries LLC, a move which has strengthened the brand on a global basis. Sales exceeded expectations. Autogard and Rexnord Power Transmission customers alike had access to a greater portfolio of products and world reknowned brands, allowing them a complete power transmission solution package.

So what can you, the Autogard customer, look forward to in 2012?

The internal engineering team has been expanded to work on even more new and updated products – so keep checking the website for updates! There will be capital investment taking place in the Cirencester factory to increase our production capacity and ensure we can meet the lead time demands of you, the customer.

Torque Limiter keeps Filter Gates moving

A power station based on the coast of England, draws water from the plentiful supply of sea water that surrounds half of its perimeter. Unfortunately the tidal flow also brings some unwelcome debris, for example sea weed, branches, and rags. Therefore to trap this unwanted debris, the sea water passes through a filter gate.

To clear the filter then requires the gate to be raised and the filter cleaned. The gate is lifted by a large chain drive system. However, the debris can sometimes be so obstructive and dense that the gate gets jammed on its upward travel. The weakest link(pardon the pun) in the drive system is the chain, which snaps when the gate gets jammed, causing damage to the drive cover and requiring expense and downtime to repair.

400 SeriesAfter a visit by an Autogard engineer, the power station was advised to fit a 406 torque limiter between the drive motor and the input shaft of the first gearbox in the drive train. The 406 is a torque limiter with an elastomeric Samiflex coupling hub fitted. The first time after fitting the torque limiter that the gate was raised, a jam occurred on the gate’s upward travel. The torque limiter immediately dis-engaged, preventing the drive operating. Operators were then able to clear the obstruction to the gate and reset the drive, preventing any damage and saving hours of downtime and the cost of replacing the chain.
