AG6-30R1worm gearIntroduction:

worm gearWorm gears, as small yet capable of achieving high speed ratios, are commonly used in reduction devices. If classified according to the installation position of the gear shaft,worm gearWorm gears and helical gears with staggered shafts belong to the category of staggered shafts. A gear with threads cut on a cylindrical material is called a worm, and a gear that meshes with it at a 90 degree angle is called a wormworm gearWhen used in combination, it is called a worm gear pair.worm gearThe application history of worm gear is long, according to Archimedes' account, it existed around 250 BC.

worm gearWorm gears can be roughly divided into two categories.

One is a cylindrical worm and one that meshes with itworm gearThat is, cylindrical worm gear pair. Another type is the drum shaped worm and the one that meshes with itworm gearThat is, drum shaped worm gear pair.

worm gearWorm gear has a smaller volume than spur gear (cylindrical gear/spur gear) and can achieve a larger reduction ratio, making it more suitable for narrow spaces. The reduction ratio is determined by the number of worm teeth andworm gearThe number of teeth determines. KHK standard productworm gearThe reduction ratio of the worm gear is 1/120.

worm gearWorm gears have the advantages of low noise and vibration. Due to the fact that power transmission is achieved through frictional contact,worm gearWorm gears also have disadvantages such as easy heating and low transmission efficiency. The transmission efficiency of cylindrical worm gear pairs is generally 30-90%

In order to suppress and reduce wear, worm gears are generally used with a ratio ofworm gearMade of harder materials. The worm gear of KHK standard gear generally uses mechanical structure specific carbon steel (S45C), alloy steel (SCM440), stainless steel, etc,worm gearThen cast iron (FC200), phosphor bronze, aluminum bronze, and engineering plastic MC nylon are used.

Generally, the left and right tooth surfaces of a worm have the same lead, but there are also worms made by changing the lead, which are called double lead worms. Using this dual lead methodworm gearWhen using a worm gear, a wedge can be used to change the axial position of the worm gear, therebyworm gearThe tooth clearance of the worm gear has been adjusted. In addition, when the teeth have worn out to a certain extent, this method can also be used to readjust the tooth spacing. The advantage of this approach is that it can avoid readjustingworm gearThe assembly distance of the worm gear reduces maintenance time.

useworm gearWhen using a worm gear, it is generally considered as the driving force,worm gearAs the driven party. However, when the lead angle of the worm is small, sometimes it may occur thatworm gearThe situation where the worm cannot be driven. This situation is called self-locking, which has the effect of preventing reversal.

worm gearWorm gears are generally used in mechanisms such as gearboxes, elevators, industrial machinery, pulleys, fishing gear, and steering systems in automobiles.
