helical spiral bevel gear motor

Helical Inline Gear Motors Helical gears are not specifically comparable to worm or bevel gearbox systems. They are actually an alternative solution to spur gears where in fact the tooth are parallel to the axis of the apparatus itself. For example, within an inline application, you can have either spur OR helical gears. An inline helical gearbox motor will usually be quieter and will carry higher loads than motors using a spur gearbox. They could be more costly in initial cost, and manufacturers need to take into account axial thrust. However, the fact that the helix position may differ from 15 to 30 degrees allows for flexibility in conditions of design. They are found in in-line applications and also parallel shaft applications.

The advantage of helical gears is that it produces a rolling action, is quieter, and has less vibration in comparison to spur gears. In addition, it produces less friction and allows for more tooth to be engaged concurrently as the teeth roll across each other.
There are myriad types of gearing. Some manufactures make use of spur gears rather than helical gearing, for instance. However, there is not as much surface contact, as noted above and as a result there is more noise and less torque transfer possible.

Another program where noise is usually common are planetary gear systems, where the one gear is totally within the other. They also require grease lubrication and they must be built with expensive materials to be able to maintain a long-existence and bearing integrity. An easier variant, internal gearing, suffers from the same problems and can only be utilized with parallel shaft.

Finally, hypoid gearing could be best understood since similar to bevel gearing, but with the apparatus axes not intersecting. The helical spiral bevel gear motor sliding actions can create large amounts of heat and the alignment requires great care.
