Bolton Engineering standard stock metric bevel gears complement the existing range of diametral pitch gears to provide the designer a wider range of selection. Available in 4 standard ratios with 9 different pitches ranging from 1.0 Mod to 5.0 Mod, these bevels provide the ideal solution for many right angle drive applications form light instrumentation to rugged manufacturing plant and agricultural equipment.
All gears are manufactured in medium carbon steels for high strength and durability, and can be optionally induction/ flame hardened for arduous applications. The gears are to the gleason system with 20 degree pressure angle, and supplied only in pairs to ensure correct matching.
For long life and efficient operation it is essential that mitre gears are correctly mounted on rigidly supported shafts with bearings able to support the axial and radial loads imposed. The shafts should be a true right angle within the following tolerances:-
Shaft axis to interest with 0.025mm. Shafts to be at right angles with +- 5’ angle. The mounting distance (Dimension A) to be true within +0.0/-0.05mm.
