Description
Modern engineering has increasingly high demands on gears for
strength, reliability and durability. This leads to the need to
apply finishing technological operations to the lateral surfaces of
the teeth of the cut gears. To gear finishing operations include
running in, shaving, lapping, gear-tooth honing and gear grinding.
The first two processes are used for non-hardened gears, and the
last two - for hardened.
Consider grinding the side surfaces of the teeth.
Gear grinding, used for final shaping profiles of hardened gears -
the operation is complicated and expensive. During the heat
treatment of gears, the profiles of their teeth are distorted. To
eliminate this and other defects, grinding is used, which makes it
possible to obtain 3rd to 7th accuracy grade of gears and the
required roughness Pa = 0.**0.6 μm
The proposed gear-grinding machine models 5Ð**1 and ***3E works by
the running-in method with the help of a simple grinding wheel
shape. On the machine model 5A**1 and ***3E grind only cylindrical
gears with straight (spur) and helical teeth. The profile of the
grinding wheel is simple - does not require constant dressing. In
one pass operation, the machine grinds simultaneously both side
surfaces of two adjacent teeth, transitional surface and
cavity.
