How are pulleys used to change the chuck speed of a pillar drilling machine?
The pulley attached to the motor usually has a large wheel on bottom, two medium wheels in centre of the stack and a small one on top. The front, or spindle pulley, is fitted with the large wheel on top. The drive belt can go from top at back, to top at front -thus driving the spindle slowly. If you changed the belt to the big motor pulley and a small spindle pulley the spindle would rotate faster.
How do you gear down one quarter hp motor to run a 55 gallon barrel at 12 to15 RPMs what size pullys or sprockets?
Assuming the motor runs at about 3000 RPM, The speed must be reduced by factor of about 200 for 15RPM. Two sets of pulleys or gears would be best. Gears with a chain would not be good due to the high motor speed. You could get 180:1 by putting a 2" pully on the motor, and running a belt to a 30" pulley which is on a shaft along with another 2" pulley, and run that pulley to another 24" pulley. If the barrel is well-mounted and freely turns, you could use it as the second pulley, since it has a 24" approximate diameter. You can also use three sets of pulleys, making it esier to find them. example: 2" motor to 12" on shaft 1 2" on shaft 1 to 12" on shaft 2 2" on shaft 2 to a 10" or 12" one driving the barrel. Consider buying a used worm gear reduction drive to save alot of this trouble. The motor can drive it directly and they come in different ratios.
What are examples in machinery of things that are very tight?
Spindle and bearing assembly, Different shafts and bearing assembly, Spindle and pulley assembly, bed and leg assembly, machine and motor assembly.
What is bench drill press?
A bench drill press is a large drilling machine that stands on a very heavy steel base. A 3" steel column extends up 3 feet for a bench model. At the top of this column is an elongated box with the motor at the back, driving a shaft with a 4 tier pulley above it. The front of the box contains a hollow shaft with a spindle inside it. The spindle also has a 4 tier pulley on top. The hollow shaft can be wound up and down by the side control lever. lowering or raising the drill shaft and chuck, A belt between the 2 pulleys drives the spindle and the chuck connected to it's lower end. In the middle of the column, a table, usually about 15 " square can move up and down the column to adjust work height.
What is the difference between an electric motor and an electric generator?
HOW ARE ELECTRIC GENERATORS DIFFERENT THAN MOTORS? There is no fundamental difference between an electric motor and an electric generator or dynamo. In normal use, all motors behave as generators, and all generators behave as motors. DC Motors act like generators because they use less electrical energy when allowed to spin fast. DC generators act like motors because they become easier to spin when less electrical energy is drawn from their terminals. For example, connect two small DC magnet motors together. Then if you spin the shaft of the first motor, the second motor's shaft will start spinning too. One acts as a DC generator, and the other acts as a DC motor. Or, spin the second one's shaft, and the first one will start spinning. Another example: If you connect a small DC motor to a small battery, then an electric current will appear in the motor's coils, and the motor starts spinning. But if you spin the motor's shaft slightly faster than the normal speed, the direction of current in the circuit will reverse, and the battery starts taking in energy from the motor. The motor has become a generator, and it's recharging the battery. Here's a good way to visualize what's happening. Imagine two pulleys connected by a rubber drive-belt. If you spin the first pulley, it pumps the belt into motion, and the second pulley starts spinning. Ask yourself this: which one is the generator? Answer: both and neither. A pulley is just a pulley. Of course we can *force* a pulley to behave like a motor: let the pulley rub against a moving belt, and the pulley will start spinning. Or we can turn it into a generator: turn the pulley, and the belt will be forced to move. In electric circuits the wires contain a circular "belt" made of electric charges (the electron-sea within the metal.) And as with the pulleys, the "belt" inside an electric circuit will slowly move along just like a leather belt. (You cannot see individual electrons, so when crowds of electrons start moving inside the wires, you cannot see any motion.) Or pretend that you have two water pumps which are connected together with hoses. Fill the pumps and the hoses with water. Now, when you turn the first pump, the pressure inside the "water circuit" drives the second pump into motion. This shows you that all pumps are motors, and all motors are pumps. It just depends on for which purpose they're employed. COILS AND MAGNETS Here's a simple electrical experiment which shows what's happening with motors and generators. Get two coils of wire wrapped on hollow plastic spools. Connect their wires together. Get two powerful bar-magnets and place the end of each magnet inside each spool. Now if you jerk one magnet suddenly, the other magnet will feel a kick. What happened? By suddenly yanking the first magnet, the first coil created a voltage because of "Lenz-Law Induction." This voltage caused all the charge in both coils to begin moving along. That created a magnetic field in the second coil, which gave the second magnet a kick. Motors and generators are based on this phenomenon. AC MOTORS AS GENERATORS But what about AC motors? And what about DC motors which use a "field coil" but no permanent magnets? If you spin either of these, a voltmeter will show no voltage. It's because you aren't using them correctly. To act as a generator, an AC motor needs to be connected to a power grid or to a large-value capacitor. And a DC field motor needs to be connected correctly (series-wound motors must be shorted, while parallel-wound motors must be left open.) And finally, these types of motors can only generate a voltage/current if they're spinning FAST. It takes awhile for tiny initial currents to build up. When no permanent magnets are present, and all you have are moving coils and pieces of metal, it takes current to make current. The current and voltage gradually build up because of a positive-feedback process, and this process doesn't kick in until the motor's shaft is turning faster than a certain speed. MODERN MOTORS DISCOVERED ACCIDENTALLY The modern DC motor was not designed as a motor. In the middle 1800s, inventor Zenobe Gramme was trying to build an electric generator which gave a very smooth output voltage. He did this by using many coils with overlapped fields. Because of it's smooth DC output, such a generator could replace large banks of batteries being used at the time. In 1873 one of his assistants accidentally connected two of his generators together. The first generator was being spun by a steam engine, and the second one unexpectedly started spinning like a motor. The "Gramme Machine" has been used ever since, under the name "DC motor" or "DC generator."
Does a pulley that goes around a motor come off?
That depends on how the pulley is mounted on the motor. If the pulley is welded then no most likely you will have to cut it to get it off. However, if the pulley is fixed to the motor using a bolt/s or other fasteners then yes. Warning: The pulley could be press fit onto the motor. If this is the case it can come off but might not be able to ever go back on.
How do you Replace a pulley that runs the motor belt?
By replacing the motor with another circular motor.
how do you remove pulley from motor on a roper dryer?
You have to unscrew the hex nut that is attaching the pulley to the motor. It can be relatively difficult so get a torque wrench.
If you have motor rpm motor shaft sizeblower pulley size how you get blower rpm?
Drive Pulley = pulley on motor Driven Pulley = pulley on blower First determine your Ratio - divide large pulley size by small pulley size this will give you gear ratio, Example 2" drive pulley and a 4" Driven Pulley = 2:1 gear ratio If you know your motor shaft RPM divide that number by the ratio to get the RPM of the driven pulley, if your shaft rpm is 1800 rpm you would divide 1800 by 2 which would = 900 rpm on your driven pulley if your drive pulley is larger than than your driven pulley you multiply the rpm by the ratio example 1800 rpm x 2 = 3600 rpm
How do you know if motor is locked up?
A motor that is locked up cannot make a rotation. The motor will not turn over or start. Try to turn the main pulley. When the pulley cannot be by just, the motor is locked up.
What does it mean when the belt is slipping off the tensioner on a 1988 s-10 blazer 4x4 2.8l engine?
The tension pulley or any one of the other pulleys is not square to the motor. Possibly the bearing in the pulley is going and allowing the pulley to tilt. The tension pulley does wear out usually quicker than one of the components the belt drives.
If the belt on a 1993 Pontiac Bonneville got lodged between the pulley and the motor would this cause the power steering to go out?
I would be more apt to believe that the power steering pump failing would have caused the belt to jump off and become lodged between the pulley and the motor than the other way around.
You replaced the tensioner pulley and bearing assembly on a 3.0 2000 ford ranger after replaceing the pulley assembly it still has wobble Is there a spacer that fits between the shaft and bearing?
check you motor mounts and trans alignment your pulley shouldn't wobble with a new assembly
How does the idler pulley look on a jeep motor?
In an Inline 6 Jeep engine, the idler pulley is located to the right of the A/C pulley. It is a smooth pulley, not a grooved one.
What do pulley motor cars do?
the pu;;ey transfer the mechanical energy from the motor to the wheels.
What the difference between a driven and a driven gear?
The "driving" or drive gear is the source of power or rotation. The driven gear is turned or moved by the drive gear. Example: The pulley on a motor is the drive pulley and a pulley on a pump is the driven pulley. Example: The pinion gear in a differential is the drive gear and the ring is the driven gear.
How do you get the pulley off of a 12.5 Briggs and straton motor?
You need a socket with a long extension to go through the center of the pulley/shaft to locate the nut. You will have to block the pulley or the motor to keep it from turning while you are removing/replacing the nut.
