Gear in Draw-works. Draw-works is the machine on the rig consisting of a large-diameter steel spool‚ brakes‚ a power source and assorted auxiliary devices. The primary function of the draw works is to reel out and reel in the drilling line‚ a large diameter wire rope‚ in a controlled fashion. The drilling line is reeled over the crown block and traveling block to gain mechanical advantage in a "block and tackle" or "pulley" fashion. This reeling out and in of the drilling line causes the traveling

GEAR BOX high torque is required at the driving wheels when a vehicle is starting from rest‚ climbing a hill or accelerating. Gear set - permit the engine crankshaft to revolve at a relatively high speed while the wheels turn at slower speeds The driving force or tractive effort used must be equal to the total resistance of the forces opposing the motion of a vehicle and keeping it moving along a road at uniform speed [Air or wind resistance‚ gradient resistance‚ and Rolling resistance].

Gears of War is a military science fiction third-person shooter video game developed by Epic Games and published by Microsoft Studios. It was initially released as an exclusive title for the Xbox 360 in November 2006 in North America‚ Australia‚ and most of Europe. A Microsoft Windows version of the game was developed in conjunction with People Can Fly and released a year later‚ featuring new content including additional campaign levels‚ a new multiplayer game mode‚ and Games for Windows - Live functionality

turning. Once a motor has reached a number of revolutions per minute‚ it is advisable for the operator to increase the gear‚ to drop the revolutions on the motor‚ yet still keep the same amount of power created. This reduces wear on the engine‚ allows more control‚ and allows greater speeds. Although‚ in practise‚ the main use of a Gearbox is to act as a reduction gear. These can be variable or non-variable‚ depending on the application. In other words‚ if when the motor is turning 2500

Activity 1.1.3 Gears - VEX Introduction You do not have to look far to see gears. You might not think of an object such as a computer as having a lot of moving parts‚ but the CD tray on your computer is likely controlled by gears. A traditional watch is full of gears. The watch has one source of power or input that must move multiple hands continuously and at different speeds. Some watches also keep track of the day of the month. This may be low-tech by today’s standards‚ but imagine the challenge

SUPERFINISHING EFFECTS ON HYPOID GEARS SURFACE FINISH AND TRANSMISSION ERRORS Jack Masseth ∗ Gear Design & Development‚ American Axle and Manufacturing Inc. 1840 Holbrook Ave.‚ Detroit‚ MI‚ USA ABSTRACT There are several geometric and working parameters‚ besides offset‚ that have minor effects on hypoid gears efficiency (i.e. spiral angle‚ pressure angle‚ lubricant type & temperature‚ surface finish‚ etc.). Some theoretical analyses of mechanical efficiency of hypoid gears show that surface finish has

improvement on noise reduction and efficiency of gears in diesel engine Thesis: In most machines‚ the major requirements for gear transmission are low sound excitation character‚ a high-level load carrying capability and generally high efficiency‚ which is more vital with increased environmental awareness. This paper discusses and analyzes two main elements gear system efficiency improvement and sound excitation. The main reason in noise reduction at gear system is given. Recommendations for reduction
