The Mystery of Diesel Lost at Sea

Gear Technology readers know diesel—because of the fuel’s properties, such as viscosity, lubricity, and combustion characteristics—can influence the design considerations for gears within the diesel engine. What our readers might not know is on September 30, 1913, The New York Times led with a headline that Rudolf Diesel—multimillionaire inventor of the diesel engine and international superstar in the scientific community—had disappeared from the passenger steamship, Dresden, crossing from Belgium to England and was presumed dead.

Determination of Maximum Loads for Drivetrain Components in Thrusters Using Flexible Multibody-System Models

The usage of modern thrusters allows combining the functions of the drive and the ship rudder in one unit, which are separated in conventional ship propulsion systems. The horizontally oriented propeller is supported in a vertically rotatable nacelle that is mounted underneath the ship's hull. The propeller can directly or indirectly be driven by an electric motor or combustion engine. Direct drive requires the installation of a low-speed electric motor in the nacelle. This present paper concentrates on indirect drives where the driving torque is transferred by bevel gear stages and shafts from the motor to the propeller.

A Mechanically Marvelous Sea Saga

In the summer of 1974, long before Argo, there was “AZORIAN” -- the code name for a CIA gambit to recover cargo entombed in a sunken Soviet submarine -- the K-129 -- from the bottom of the Pacific Ocean. The challenge: exhume -- intact -- a 2,000-ton submarine and its suspicious cargo from 17,000 feet of water.

Reassembling Gear Drive History

Getting rid of personal mementos is an arduous housekeeping ritual for some of us; every last gear has a memory. One man’s trash is another man’s gold, after all, or in some cases, one failed business is a forgotten piece of personal and mechanical genealogy. Such is the case of the Hill-Climber chainless bicycle, the remains of which were pulled from a family junk pile after nearly half a century.

The Alignment of High Speed Gears

This paper reviews the necessity for detailed specification, design and manufacture to achieve required performance in service. The precise definition of duty rating and a thorough understanding of the environmental conditions, whether it is in a marine or industrial application, is required to predict reliable performance of a gearbox through its service life. A case study relating to complex marine gears and other general practice is presented to review the techniques used by Allen Gears to design and develop a gearbox that integrates with the requirements of the whole machinery installation. Allen Gears has considerable experience in the design of a variety of industrial and marine gears(Ref. 1,2).
