What three gears make up a complete planetary gear system?
The gears in a planetary gear system are the drive gear, ring gear, and planetary gear.
Difference between helical gear and bevel gear?
A bevel gear provides torque and rotation at 90 degrees, and a helical gear provides it at 180 degrees.
Does an idler gear change the speed of the driver gear?
No. But if there are two idler gears, one smaller than the other, say a 12 tooth and a 6 tooth. the 12 tooth idler is the idler of the driver gear which has 24 teeth, making the idler gear rotate 2 times for every rotation that the driver gear rotates. Now, if the 12 tooth idler gear is rotating 2 times faster than the driver gear, then the 6 tooth idler gear will rotate 2 times faster than the 12 tooth idler gear. So, the 6 tooth idler gear is rotating 4 times faster than the driver gear. Let's say that the driven gear has 12 teeth. For every rotation of the 6 toothed idler gear, the driven gear rotates halfway.
What is the most important gear in the world?
All gear is important.
Is a gear a simple machine?
Transmission of Motion: Gears transmit motion and rotational force from one shaft to another. Speed and Torque Modification: Depending on the sizes and arrangement of the gears, they can be used to increase or decrease speed and torque. Directional Changes: Gears can change the direction of rotational motion from clockwise to counterclockwise or vice versa.
What is back gear attachment in lathe?
The back gears on a lathe can be changed to enable it to cut an even wider variety of thread pitches.
Gears on a center lathe?
Without knowing what the question is, I provided a couple of sites that might help:The headstock of a centre lathe can be opened, revealing an arrangement of gears. These gears are sometimes replaced to alter the speed of rotation of the chuck. The lathe must be switched off before opening, although the motor should automatically cut off if the door is opened while the machine is running (a safety feature).The speed of rotation of the chuck is usually set by using the gear levers. These are usually on top of the headstock or along the front and allow for a wide range of speeds.However, sometimes the only way to set the lathe to a particular speed is to change the gear arrangement inside the headstock. Most machines will have a number of alterative gear wheels for this purpose.* http://www.technologystudent.com/equip1/mlathe1.htmThere are many variants of lathes within the metalworking field. Some variations are not all that obvious, and others are more a niche area. For example, a centering lathe is a dual head machine where the work remains fixed and the heads move towards the workpiece and machine a center drill hole into each end. The resulting workpiece may then be used "between centers" in another operation. The usage of the term metal lathe may also be considered somewhat outdated these days, plastics and other composite materials are in wide use and with appropriate modifications, the same principles and techniques may be applied to their machining as that used for metal.* http://en.wikipedia.org/wiki/Metal_lathe
What is an all gear lathe?
A lathe in a small wood or metal shop has a motor that connects to the lathe by belt. In a "direct drive" lathe the motor connects directly. I assume that "all gear" means direct drive, no belt. A belt drive protects the motor from damage and reduces vibration of the lathe. In addition, the belt allows you to change the gear ratio and thus the speed of the lathe without changing the motor speed. Belt drive is superior in terms of both performance and longevity.
What are the functions of gear train on a lathe machine?
All gearboxes work the same way: there is a gear on the motor, a gear on the thing you're trying to drive, and sometimes a set of gears between the two. The ratio between the gears, plus the RPM of the motor, determines the speed of the workpiece. If the gear on the motor is larger than the gear on the workpiece the RPM of the workpiece will be higher than the speed of the motor. If the workpiece's gear is larger, the workpiece will turn slower than the motor. Given that, though, I've never seen a gearbox on a wood lathe. Wood lathes use belt drive for two reasons, the most important being safety--if you get a catch, a workpiece on a belt driven lathe won't damage you as badly as a workpiece on a gear-driven lathe. Also, belt drive won't feed vibration from the workpiece back into the motor and damage the bearings. Gear drive is used on metal lathes.
What is the difference between a milling machine and a lathe?
A milling machine basically look like a drill press, but with the ability to move the work piece sideways. A lathe clamp and spin the work piece horizontally and use a stationary tool bit to cut and shape the work piece.
What is lathemachine and describe its main parts?
A lathe is a woodworking or metal working machine that rapidly turns the item to be lathed, A blade is then brought to the item in the case of wood a chisel can be used by hand and in the case of metal the blade is held in a specially made jig , the blade slices away metal until the round shape required is acquired. An example of an item that can be made on a lathe is a Baseball bat.
How are spindle speed changed in the lathe machine?
Using geared head for gear box driven or stepped pulley if belt driven
How do you change gear in Maruti 800?
in the H type groove, towards the front left position is the first gear ,straight back is the second gear.Towards right front is the third gear and straigth back is the forth gear. Towards the rightmost back is the reverse gear.Centre of the Groove is the neutral.
Do you ever get your gear back in World of Warcraft when your account has been hacked?
Yes, you can get your gear back, but it might take a few days.
Which Bakugan can conect with battle gear?
You can connect battle gear on bakugans with pegs on the back of them
How do you measure gear back lash?
back lash means it is the clearance between the low speed gear teeth and high speed gear teeth and it is measured by using the magnetic plunger dial
What is back lash with respect to rear axle?
Back lash is best described as how much the pinion gear will move before contacting and moving the crown gear. This is specified and measured on the crown gear.
