We can supply a large and varied gears, produced from steel. The gears are designed according to customer needs and specifications for machines in the labeling, converting and other sectors.
Gears subjected to high operating stress, need the high strength of a hardened structure in order to reduce the likelihood of repairs. Machine components such as gears usually require a hardened structure to resist wear and deformation.
TYPES OF GEARS
The teeth of a spur gear have an involute profile and mesh one tooth at a time. The involute form means that spur gears only produce radial forces (no axial forces), but the method of tooth meshing causes high stress on the gear teeth and high noise production. Because of this, spur gears are typically used for lower speed applications, although they can be used at almost any speed.
One of the most noticeable benefits of helical gears over spur gears is less noise, especially at medium- to high-speeds. Also, with helical gears, multiple teeth are always in mesh, which means less load on each individual tooth. This results in a smoother transition of forces from one tooth to the next, so that vibrations, shock loads, and wear are reduced.
- Hardened / ground (Class 5-6)
For through-hardened gears, the parts are heated in a furnace to the proper temperature and then dropped into a quench medium such as oil. For some alloy steels, the parts may be air-cooled with a stream of cool, inert gas blown over the part while it remains in the oven after the heating cycle. The gears are then tempered to final working hardness.
