Often the term transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device. In British English, the term transmission refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive), differential, and final drive shafts.
A gear or cogwheel is a rotating machine part having cut teeth, or in the case of a cogwheel, inserted teeth (called cogs), which mesh with another toothed part to transmit torque.Geared devices can change the speed, torque, and direction of a power source.Gears almost always produce a change in torque, creating a mechanical advantage, through their gear ratio, and thus may be considered a ...
Most modern automatic gearboxes have a set of gears called a planetary or epicyclic gear train.. A planetary gear set consists of a central gear called the sun gear, an outer ring with internal gear teeth (also known as the annulus, or ring gear), and two or three gears known as planet gears that rotate between the sun and ring gears.. The drive train is coupled to a mechanism known as a ...
A locking differential is designed to overcome the chief limitation of a standard open differential by essentially "locking" both wheels on an axle together as if on a common shaft. This forces both wheels to turn in unison, regardless of the traction (or lack thereof) available to either wheel individually. When the differential is unlocked (open differential), it allows each wheel to rotate ...
The Honda Fit (Japanese: ホンダ・フィット, Honda Fitto), also marketed as the Honda Jazz (Japanese: ホンダ・ジャズ, Honda Jazu), is a five-door, front-engine, front-wheel drive B-segment subcompact car manufactured and marketed by Honda since 2001 and now in its third generation.
The central carrier and associated spider gears interface directly to two crown wheels connected to the front and rear drive shafts; The two crown wheels interface to the spider gears at different diameters, and so produce different torque when turned by the spider gears. This is engineered to produce a 40:60 static torque split front and rear.

Front-wheel-drive cars use the same transmission principles as rear-wheel-drive cars, but the mechanical components vary in design according to the engine and gearbox layout. Transverse engines are normally mounted directly above the gearbox, and power is transmitted through the clutch to the gearbox by a train of gears.
Worm gears are used on many lift/elevator and escalator-drive applications due to their compact size and the non-reversibility of the gear. In the era of sailing ships, the introduction of a worm drive to control the rudder was a significant advance. Prior to its introduction, a rope drum drive controlled the rudder.

When designing gears for FDM fabrication in ArtOfIllusion there are two essential things to bear in mind: The basics of conventional gear design, and the accuracy or lack thereof in the manufacturing process. So, before we get stuck in to the AoI nitty-gritty, here's an Express Guide to Gear Design. Back to Index. Gear Design Basics
Jan 05, 2003· Four planetary stages are supplied with the gearbox, two 1:4 and two 1:5, and any combination can be selected. Not only is this a good drive for small mechanical applications, it provides an excellent review of epicyclic gear trains. The gearbox is a very well-designed plastic kit that can be assembled in about an hour with very few tools.
Finally, gearboxes usually come with specifications on the maximum speed allowable at the input shaft and the maximum torque allowable at the output shaft. Choosing a Motor and Gearing Combination. To choose a motor and gearbox appropriate for your application, consider the following issues: What is the typical power you need?
gear drive[′gir ‚drīv] (mechanical engineering) Transmission of motion or torque from one shaft to another by means of direct contact between toothed wheels. Gear Drive a mechanism consisting of toothed wheels that engage and transmit rotary motion, usually transforming angular velocity and torques. Gear drives are classified according to the ...
Design Gearbox mechanism Output shaft 1 Input shaft Output shaft 2 Selector shaft In a conventional gearbox, an input shaft trans-fers drive force to an output shaft on which the various gears are positioned. The more gears there are lined in row on such a drive shaft, the longer it will be. For the so-called short gearbox, one of which is

Design of Spur Gears: Sometimes, the spur gears (i.e. driver and driven) are to be designed for the given velocity ratio and distance between the centers of their shafts. Let x = Distance between the centers of two shafts, N 1 = Speed of the driver, T 1 = Number of teeth on the driver, d 1
gears can be considerably less than or the crossed link but nevertheless will be more than of a comparable circular gear. Elliptical gears have not been widely uses in industry because of difficulties in their design and manufacture inspite of their usage and application in irregular rotational motion as in flying shears, flow meter etc.
Understanding Motor and Gearbox Design: Why Spend Time Choosing the Right Motor and Gearbox? Choosing the correct combination of a motor and a gearbox for a given application is very important, both in the FIRST Robotics Competition (FRC) and in actual engineering projects. Without app...
Gearbox Design and Application Overview Regardless of the initial conceptualization approach, engineering and design must identify the gearbox application, gear configurations / type and packaging requirements. Gear Motor Transmission Inertia Drive Calculator
Bevel gears that have pitch angles of greater than ninety degrees have teeth that point inward and are called internal bevel gears. Bevel gears that have pitch angles of exactly 90 degrees have teeth that point outward parallel with the axis and resemble the points on a crown. That's why this type of bevel gear is called a crown gear.
Planetary gears, which can supply a ... The planets, spaced around the central axis of rotation, mesh with the sun as well as the fixed ring gear, so they are forced to orbit as they roll ...
A manual transmission (also known as a stick shift, straight drive, or standard transmission) is a type of transmission used in automotive applications. Manual transmissions often feature a driver-operated clutch and a movable gear selector, although some do not.
The gearbox was a Maybach type 40 12 16 Olvar pre-selector manufactured by either Maybach, Zahnradfabrik or Adterwerke under license from Olvar-Getriebe. It had eight forward and four reverse gears. The gearbox also had power takeoffs for the turret hydraulic drive and the bilge pump. With light controls, the gearbox was easy to operate.
Apr 04, 2019· To determine gear ratio of a gear train with 2 gears, start by identifying your gears. The gear attached to the motor shaft is considered the first gear, or the “drive gear”, and the other gear, whose teeth are meshed with the drive gear, is considered the second gear, or “driven gear.”
An elevator or lift is a vertical transport vehicle that efficiently moves people or goods between floors of a building. They are generally powered by electric motors that either drive traction cables and counterweight systems, or pump hydraulic fluid to raise a cylindrical piston.

Spur Gears have straight teeth and are usually mounted on parallel shafts. They are the simplest in design and the most widely used. External spur gears are the most common, having their teeth cut on the outside surface, also available are internal spur gears and rack and pinion gears.
In designing plastic gears, the effects of heat and moisture must be given careful consideration. The related problems are: Backlash: Plastic gears have larger coefficients of thermal expansion. Also, they have an affinity to absorb moisture and swell. Good design requires allowance for a greater amount of backlash than for metal gears.
