WABCO Offers 8-page Brochure

On Logicmaster™ Marine

Propulsion Control Systems

The WABCO Fluid Power Division of Ameri- can-Standard, Lexington, Ky., has published an eight-page brochure on Logicmaster™ pneu- matic control systems for marine engines equip- ped with hydraulic clutch reverse gears.

WABCO Logicmaster controls incorporate the interlocks and protective circuits required for proper engine and reverse gear operation without relying on operator judgement to time or anticipate propulsion machinery functions.

Features listed in the publication are remote single-lever "fingertip" control; fast maneuver- ing; maximum protection for propulsion ma- chinery; compact, space-saving components; and factory assembled and 100 percent opera- tional tested.

Service proven interlocks and features of

Logicmaster control systems are discussed along with different systems that may be selected, such as the LM1 standard system, LM2 stan- dard with shaft brake control, and LM3 propor- tional reversing interlock system, designed for high-speed vessels like crewboats, which operate on reversal to utilize the engine compression to decelerate the propeller and shaft to idle before reverse clutch engagement. Operating sequences are also given for the systems.

All Logicmaster systems have the new HD- 2-FC Controlair® valve and the Logicmaster

Control Unit, and the features of both are listed.

The brochure is well illustrated with photos and drawings, among which is a one-page draw- ing of a typical two-station, single-engine con- trol system package with listed available op- tions.

Availale From Falk On New

Shaft Speed Reducer Line

Many significant improvements are claimed for a new line of gear-type speed reducers intro- duced by the Falk Corporation, Milwaukee,

Wise. Essentially the new line, carrying a new "A" Unit designation, combines significantly higher performance with reduced space require- ments. In making the announcement, a Falk spokesman stressed that the new design is an improvement on a good thing, noting that Falk has been a leading U.S. producer of parallel shaft reducers for more than 25 years.

A full-color 12-page brochure on Falk "A"

Unit parallel shaft speed reducers is offered free by the company. The attractive publication uses photos, drawings, diagrams, etc., as well as text to describe and point up the advantages of the new line.

Primary among the new improvements is the use of computer-aided design and finite element analysis as a means of putting more strength into a more compact speed reducer package.

Similarly, advanced case carburizing techniques produce gears that are both stronger and longer wearing. A spokesman noted that even the bear- ings of "A" Unit reducers are state-of-the-art, providing added load-carrying capability. Effec- tive thermal design, primarily through efficient use of fans and cooling tubes, are said to be carried forward from previous designs as an important contributor to reliable performance.

Along with the "A" Unit's state-of-the-art design, Falk has employed leading-edge manu- facturing techniques designed to improve reli- ability and performance. Housings are 100 per- cent robot welded, and modern two-stage ovens add precision and control to the heat treating and hardening of gears to highest practical

Rockwell hardness. Another advanced tech- nique is "gear tooth lead and pinion profile modification"—an engineer's way of saying that tooth contact under load is optimized for lower stresses and longer life.

Not new but very important to the unit are the Magnum Seals that are standard and said to eliminate oil leaks and to prevent dirt and grit from entering the bearing chamber. "A" Unit reducers are available for single- speed reductions from 1.8 to 1, and more than 400 to 1 with multiple reductions. Torque rat- ings range from 130,000 inch-pounds to more than 2 million inch-pounds. Related equipment such as soleplates, bedplates, cooling systems and backstops are also available.
