Abstract
The utility model relate to a kind of two pieces of inner plate bearing pin boss holes relatively and roller male-female engagement get sectional roller chain for sleeve function, comprise roller chain, two pin shaft holes on inner plate in described roller chain in roller chain main body are bearing pin boss hole, roller inwall is that both sides are symmetrical, the interior roll surface of intermediate annular projection, bearing pin boss hole on two pieces of inner plates inserts in the groove through hole of roller two ends relatively and the interior roll surface of roller intermediate annular projection is positioned between the bearing pin boss hole end face on two pieces of inner plates, bearing pin is through the bearing pin boss hole on two pieces of inner plates and roller and by two pieces of inner plates and roller location.Advantage: one is the whole process of saving sleeve manufacture, reduces chain manufacture cost; Two is the friction pairs reducing chain barrel and bearing pin, Biaxial beaming roller bottom bracket axle directly and roller pivoting friction, reduction chain wear.
Description
Technical field
The utility model relate to a kind of two pieces of inner plate bearing pin boss holes relatively and roller male-female engagement get sectional roller chain for sleeve function, belong to roller chain manufacture field.
Background technique
CN203023392U, title " sleeve roller chain ", be made up of inner plate, outer plate, sleeve, bearing pin and the first roller, inner plate is equal with outer plate quantity, it is characterized in that, the side of described outer plate is outwardly lug, between two outer plates of same chain link, be provided with a pivot pin by lug, pivot pin be socketed with second roller between two outer plates, the second roller is used in the respective slot of the engaging-in sprocket wheel rear support of its place chain link at sprocket wheel.Its deficiency: roller chain main body is still made up of five elements, i.e. inner plate, outer plate, pivot pin, sleeve and roller, still there are two kinds of friction pairs, abrasion loss is large.
Model utility content
Purpose of design: avoid the deficiency in background technique, if a kind of two pieces of inner plate bearing pin boss holes relatively and roller male-female engagement get sectional roller chain for sleeve function.
Design proposal: in order to realize above-mentioned purpose of design.The utility model is in structural design, and one is pin shaft hole in inner plate is designed to bearing pin boss hole structure to replace the sleeve of chain, saves the manufacturing process of sleeve, reduces manufacture cost, two is by cancelling ferrule element, by the friction fit of bearing pin, inner plate, reduces chain wear, three be in the annular protrusion in roller roll surface and and inner plate on bearing pin boss hole and bearing pin between be equipped with and generate by metal porcelain the metal porcelain that agent generates and generate agent RMP II lithium grease layer, this RMP II lithium grease layer is except possessing the performance of former lithium grease, can also run well at chain, automatically metal porcelain is carried out to friction pair (sleeve and bearing pin) surface in running, generate the cermet coating of wear-resisting property excellence, this cermet coating significantly can not only extend the working life of chain friction pair, energy efficient, and significantly can improve contact mechanics characteristic and the physicochemical characteristics of friction surface, and optionally compensate for wear surface, reduce mechanical loss, the in-situ immobilization simultaneously can not dismantled the Worn metal surface of friction pair, frictional vibration is significantly reduced, thus reduction energy consumption, and extend the working life of chain significantly.
Technological scheme: a kind of sectional roller chain, comprise roller chain, two pin shaft holes on inner plate in described roller chain in roller chain main body are bearing pin boss hole, roller inwall is the interior roll surface that both sides are symmetrical, intermediate annular is protruding, bearing pin boss hole on two pieces of inner plates inserts in the groove through hole of roller two ends relatively and the interior roll surface of roller intermediate annular projection is positioned between the bearing pin boss hole end face on two pieces of inner plates, and bearing pin is through the bearing pin boss hole on two pieces of inner plates and roller and by two pieces of inner plates and roller location.
The utility model is compared with background technique, and one is the whole process of saving sleeve manufacture, reduces chain manufacture cost; Two is the friction pairs reducing chain barrel and bearing pin, Biaxial beaming roller bottom bracket axle directly and roller pivoting friction, reduction chain wear.
Accompanying drawing explanation
Fig. 1 is the plan structure schematic diagram of sectional roller chain.
Fig. 2 is the structural representation of roller in Fig. 1.
Fig. 3 is the structural representation of inner plate in Fig. 1.
Embodiment
Embodiment 1: with reference to accompanying drawing 1-3.A kind of sectional roller chain, comprise roller chain, two pin shaft holes on inner plate 2 in described roller chain in roller chain main body are bearing pin boss hole 21, roller 4 inwall is the interior roll surface 41 that both sides are symmetrical, intermediate annular is protruding, bearing pin boss hole 21 on two pieces of inner plates 2 relatively inserts in the groove through hole of roller 4 two ends and the interior roll surface 41 of roller 4 intermediate annular projection is positioned between bearing pin boss hole 21 end face on two pieces of inner plates 2, and bearing pin 3 is through the bearing pin boss hole 21 on two pieces of inner plates 2 and roller 4 and two pieces of inner plates 2 and roller 4 are located.Inner plate 2 and outer plate adopt import alloy material (well known materials), and inner plate 2 adopts entire bright cold impact extrusion technology, form diameter 6.3mm, the boss of degree of depth 2mm.Roller 4 selects low-carbon alloy material, adopts multi-station cold-heading technology, and two-port cold-heading forms external diameter 6.35mm, the step type roller of degree of depth 2.2mm.The boss structure of inner plate 2 replaces the sleeve of chain, saves the manufacturing process of sleeve, saves manufacture cost, namely cancel ferrule element, by the friction fit of bearing pin 3, inner plate 2, reduces chain wear.Bearing pin 3 adopts high carbon steel, and by metallic cementation, improves tensile strength and the polishing machine of bearing pin.Described inner plate aperture size is changed little of 4.50mm by 6.37mm, change the anti-shearing area of little rear increase inner plate, strengthens the tensile strength of inner plate.
Embodiment 2: on the base of embodiment 1 goes out, the interior roll surface 41 of the annular protrusion in described roller 4 and and inner plate 2 on bearing pin boss hole 21 and bearing pin 3 between be equipped with and generate by metal porcelain the metal porcelain that agent generates and generate agent RMP II lithium grease layer.
It is to be understood that: although above-described embodiment to be contrasted detailed text description to mentality of designing of the present utility model; but these text descriptions; just the simple text of the utility model mentality of designing is described; instead of the restriction to the utility model mentality of designing; any do not exceed the utility model mentality of designing combination, increase or amendment, all fall in protection domain of the present utility model.
