The tooth height of CVT PULLEY SHAFT is 4 and the tooth width is
38,the gear precision:
Gear precision is a grade of gear shape synthetic error, including
tooth shape, tooth direction, diameter jump and other important
parameters.
Tooth shape refers to the radial shape of the tooth, tooth
direction refers to the longitudinal shape of the tooth, diameter
jump refers to the error of the distance between the adjacent two
teeth, generally our car gear can be processed by hobbing machine,
6~7 level can be used.
And some printing presses because of the need for high-speed
operation and batch printing, so the need for high-precision gear
to reduce the gear accumulation caused by the error and the
printing effect decreased, and the domestic production of gear
grinding machine can be processed to level 4~5, imported
high-precision gear grinding machine can be processed to level 3,
4, some can be processed to level 2. The Japanese standard DIN 0
level is equivalent to level 4 of Chinese evaluation, and the
general error is in μm, 1μm=0.001mm
The casting method
Gear castings are also known as cast steel gears. This is because
most gears are made of cast steel. Here I share some information
about the production of gear castings and related heat treatment.
Gear castings usually range in weight from a few kilograms to
several tons.
Gear castings are usually made of high carbon cast steel, but some
are made of alloy steel containing chromium, nickel and molybdenum
to achieve high tensile strength. Large gears generally have lower
physical requirements than pinions.
