Short delivery period hinge pin stepped type Accord with ISO9001
quality system for Industrial automation equipment
Hinge Pin
is a kind of standardized fasteners, which can be static fixed
connection, can also be connected with the relative movement,
mainly used for the hinge of two parts, usually form hinge pin lock
with cotter pin, reliable work, easy to disassemble.In the
application of machine tool spindles, the cantilever pin external
thread mounting and external thread type, double row precision
cylindrical roller bearings are also used, usually in combination
with precision angular contact ball bearings or thrust bearings.
These bearings can withstand large radial loads and allow for
higher rotational speeds. The two rows of rollers in the bearing
are arranged in an intersecting manner. The wave frequency is
greatly increased compared with the single row bearing, and the
amplitude is reduced by 60%-70%. These bearings usually come in two
forms: NN30, NN30K two series bearing inner ring with ribs, outer
ring can be separated.
Commonly used material
1, Steel no.45
45 steel shaft parts are commonly used materials, it is cheap after
quenching and tempering (or normalizing), can get better cutting
performance, and can get higher strength and toughness and other
comprehensive mechanical properties, after quenching surface
hardness can reach 45 ~ 52HRC.40Cr and other alloy structural steel
is suitable for shaft parts with medium accuracy and high rotating
speed. After quenching and tempering, this kind of steel has better
comprehensive mechanical properties.
No.45 steel is widely used in machinery and has good mechanical
properties.But this is a medium carbon steel, the quenching
performance is not good, 45 steel can be hardened to HRC42~46.So if
you need the surface hardness, and want to play 45# steel superior
mechanical properties, often quenching 45# steel surface
(high-frequency quenching or direct quenching), so that you can get
the required surface hardness.
2, 40 cr
40Cr is a commonly used material for shaft parts, it is cheap after
quenching and tempering (or normalizing), can get better cutting
performance, and can get higher strength and toughness and other
comprehensive mechanical properties, after quenching surface
hardness up to 45 ~ 52HRC.
40Cr and other alloy structural steel is suitable for shaft parts
with medium accuracy and high rotating speed. After quenching and
tempering, this kind of steel has better comprehensive mechanical
properties.
40Cr steel is one of the most widely used steels in the machinery
industry.After tempering and tempering treatment, it has good
comprehensive mechanical properties, good low temperature impact
toughness and low notch sensitivity.Good steel hardenability, when
water quench hardening to Ф 28 ~ 60 mm, when oil quenching
hardening to Ф 15 ~ 40 mm.This steel is suitable for cyanidation
and high frequency quenching in addition to quenching and
tempering.When the hardness is HB174 ~ 229, the relative
machinability is 60%.
