Helical gear units are designed for tough applications such as in mining and energy industries. They must provide high operational reliability in harsh conditions such as hot, humid and dusty environments, at very low speed and with heavy loads.
VL Motion Systems has been actively involved within the Food & Beverage, Alternative Energies, Waste Water, Steel and Material Handling industries and has been supplying geared motors for many years.
When people think of gears, they often think of a spur gear, the classic cog-shaped gear with simple straight teeth. Helical gears offer a refinement over spur gears. They are designed in a similar way, except that the teeth are set at an angle and engage slowly and smoothly making a helical gear quieter and smoother in operation than many other kinds of gears. In spur gears teeth suddenly meet at a line contact across their entire width causing stress and noise. For this reason, helical gears are used in almost all industrial applications.
Because of the angle of the teeth on helical gears, they create a thrust load on the gear when they mesh. Devices that use helical gears have bearings that can support this thrust load.
Their design means that helical gears tend to wear down less quickly, because the load of the force is distributed, rather than being concentrated, and the teeth are less subject to chipping.
However, a disadvantage of helical gears is a resultant thrust along the axis of the gear, which needs to be accommodated by appropriate bearings, and a greater degree of sliding friction between the meshing teeth, often addressed with additives in the lubricant.
