TECHNICAL CHARACTERISTICS
The housing shape has been optimized to maximize the draining of water or liquid in the event of the gearbox being subjected to splashing or washing.
From BOX 63 and up, 2 taper roller bearings are mounted on the wormshaft improving the mechanical resistance to the axial thrust generated by the wormwheel.
The combination of taper roller bearings and 2 nilos [mounted on the BOX sizes 75 to 110) retains the grease in the bearings even when they are not in contact with the gearbox lubricant and also permits the mounting of the whole BOX range from the size 25 to the size 110 in the positions V5 and V6 without any additional accessories.
The new patented "BOX" series of worm gear units is made with die cast aluminium housing from size 25 up to 90 and is cast iron for the size 110.
The housing has been designed using parametric 3D CAD software supported by systematic analysis of the thermal dissipation capacity and the structural resistance to deformation under the effect of working loads.
BOX units sizes 25 up to 90 are supplied with long life synthetic oil and they do not require any maintenance during their lifetime. BOX size 110 uses mineral oil, but synthetic oil is available on request.
Each gearbox is supplied with a full set of filler, level and breather plugs, permitting all mounting positions.
In order to reduce noise, improve efficiency and durability, the wormshaft is made of case hardened steel and profile ground, while worm wheel is in shell cast Bronze.
Before being assembled, the worm wheel is subjected to 'running in' to improve its surface finish and reduce noise.
A coat of paint seals minor I surface porosities in alum'mfumf and also protects the housing from | oxidation.
Mating surface are machined for perfect perpendicularity.
