Helical gears(Mining Machinery Gear)
Helical gears(Mining Machinery Gear) generally have longer and stronger teeth than the other gears. Due to the greater surface contact area on the teeth, these gears can carry a heavy load, but the efficiency is reduced because of the same reason. Forging produces helical gears that are quiet and make less vibration. These gears are very similar to spur gears, except that the teeth of helical gears are cut at an angle to the axis. An intriguing thing about helical gears is that if the gear teeth’ tips are correct, they can be raised on perpendicular shafts, where the revolving angle is adjusted by 90 degrees. These are available in both right and left-hand configurations.
The helical gears provided by us are made as per the industry’s standards and are widely used in the automotive and engineering industries. These can also be customized as per the client’s requirements. We provide helical gears upto 1000mm O.D. and 80 modules in different varieties such as hard, soft, or ground. Helical gears are pretty similar to industrial gears. They have teeth that are slanted and thus help in meshing the gear. The teeth of helical gears are connected better than those of spur gear.
They can be configured to either crossed or parallel as per the needs of the applications. When it comes to mechanics, parallel helical gears are much better. The reason behind this is that helices meet at tangents that do not happen in crossed gears, thus limiting the contact point to the tooth’s surface. So it is not advisable for applications that concern heavy loads to use crossed gear.
