What is the working principle of worm gears in sand mullers?
Sand mullers break up sand after it has been used in molds to facilitate sandcasting. By effectively breaking up the sand, it can be reused. The worm on a motor or on the "driven" side of the device will engage with a worm gear. The worm rotates continuously, and the spiral cut gears "worm" their way "along" the axis of the gear. The worm gear (or spur gear) engages with the worm and rotates continuously as well. Also, the worm gear will translate the rotary motion of the worm by 90 degrees. It is fairly easy to see how the unit works if you look at some pictures or drawings. Hey, how about some animation or video? Got a couple of links.
What type of gear is a combination of a gear combined with threads of a screw?
A worm drive.
Which gear is used for perpendicular shaft?
Worm gear
What tipe of gears are on a bicycle a spur gear a bevel gear a worm gear?
Depends. Bicycles with external gears have chain-and-sprocket gears. Bicycles with internally geared hubs have both a chain-and-sprocket gear and spur gears (usually in a planetary configuration) inside the rear hub. Then there are the rather rare shaft-drive bicycles, which use bevel gears. And maybe an internally geared hub as well. Then there's the occasional belt drive bike of course. And one or two CVT designs.
What is a Helical worm gear motor reducer?
For speed reducer gearbox just want to clarify if i can use the worm gear side of the gearbox for the installation of drive motor instead of mounting it on the enveloping worm? what is the advantage and disadvantage
What is a hobbing machine used for?
A hobbing machine is used for cutting gear teeth in gear blanks and for cutting worm, spur, or helical gears.
Is worm and wheel reversible?
yes you can reverse worm and gear. A worm gear can rotate the worm, its based on the lead angle, pressure angle and co.efficient of friction between the pairs.

How do you calculate the Differential Constant of Hobber?
well this is not impossible, it is generally calculated by manufacturere so it is also called machine constant,it cant be calculated just by looking at machine, u have to know number of teeth/ starts of worm/ of every gear, beveal, worm etc in machine to calculate exact ratio, other method is hit n trial method , u cut spur gear, then cut different gear of different helix angle and of different modules/dp, may be can get close to machine constant
What is difference between bevel gear and worm wheel?
A bevel gear is cone shaped with the gear teeth placed vertically along the periphery. A worm gear is barrel shaped with the teeth spiraling along the length like a screw.
What is the name of a gear that has big gear bottom small gear top?
This can be numerous gears, but a worm gear is extreme between the two sizes of gears.
What type of gear is a combination of a gear combined with threads of a screw?
A worm drive.
If you have a worm gear and a sprocket gear and the worm gear rotates slowly on its shaft how will the sprocket gear turn?
Even slower
Why worm is geared with worm gear Give reasons?
A worm or machine can be geared with worm gear to give it higher torque or to reduce rotational speed in the machine.
Where can one purchase worm gear online?
One is able to purchase a worm gear from many different online stores. The list of these stores includes A Main Hobbies, Robot Shop, and Hitch Anything.
What is lead in gear?
linear distance moved by the gear(worm,screw jack) for one rotation of the gear(worm,screw jack)
Which gear is used for perpendicular shaft?
Worm gear
