Selecting internal gear pumps for difficult duties

World Pumps, 2005
Internal gear pumps have always been well suited for handling a wide array of process applications. However, pump selection typically requires the materials of construction, method of sealing, NPIPa, pressure relief, fluid characteristics and shaft speed to be considered, writes Lewis E Ballard of Gorman-Rupp.

Impact Properties of Selected Gear Steels

SAE Technical Paper Series, 1978
<div class="htmlview paragraph">The unnotched Charpy impact properties of carburized 8620, 4620, 4620 + 0.3 Mo, and 3310 were studied at two case depths. The ranking of the alloys in order of increasing impact strength for both case depths was: 8620, 4620, 4620 + 0.3 Mo, 3310.

CRITERIA FOR SELECTING GEAR MANUFACTURING METHODS

Conference proceedings : 60th Anniversary of the Association of Production Engineering of Serbia
Gear can be produced on many processes, such as conventional ones like traditional machining (hobbing, shaping, milling) and forming methods (casting, forging, molding) to modern techniques like additive manufacturing. Selecting an optimal gear production method is a complex multi-criteria decision that significantly impacts the gear’s quality ...

Selection of number of gear teeth for machine tool gear boxes

International Journal of Machine Tool Design and Research, 1974
Abstract The output speeds on machine tool spindles follow a geometric progression. International and various national standards specify the permissible errors in speeds due to mechanical and electrical variations. The errors arising out of mechanical variations are mainly due to the limitations on the choice of the number of gear teeth.

Direct estimates of gear selectivity from multiple tagging experiments

Canadian Journal of Fisheries and Aquatic Sciences, 1997
A new method is introduced for estimating selectivity of fishing gear from tagging data in which data from many experiments are combined. Selectivity is modeled as a multiplicative function of length and experiment effects using a generalized linear model with a log link function and a binomial error structure.

Material Selection for Optimum Design of Planetary Gear Train used in Automobile Gear Box

SSRN Electronic Journal, 2019
Planetary Gear Trains are used in different applications like power transmitting systems of machine tools and so on. Planetary gear boxes are used frequently to match the inertias, lower the motor speed, boost the Torque, and at the same time provide a study mechanical interface for pulleys, cams, drums and other mechanical components.
