, including inner plate, outer plate, bearing pin and sleeve, the inner plate and outer plate be hinged on bearing pin, and sleeve is set with outside bearing pin, is set to excessively coordinate or interference fit between bearing pin and sleeve
,
The bearing pin two ends are provided with spindle nose, and the outer plate is arranged on spindle nose, be located on the bearing pin and the shaft shoulder I is provided between outer plate and inner plate
,
It is located on the bearing pin and the shaft shoulder II is provided between inner plate and sleeve.
Above-mentioned chain is coupled together inner plate and outer plate by the same bearing pin in solid shape, so that this three of inner plate, outer plate and connecting pin can simultaneously bear and offset the active force suffered by chain, so as to effectively improve the life-span of the chain.But the chain still has a problem that:Because bearing pin is in solid shape, and in actual product, bearing pin is made up to make it have larger hardness of Steel material, causes the whole weight of chain to increase.
The content of the invention
The purpose of the present invention is directed to existing technology and there is above mentioned problem, it is proposed that a kind of Novel chain unit, and the technical problems to be solved by the invention are how while extension service life of chain is realized, the weight of chain to be reduced again.
The purpose of the present invention can be realized by following technical proposal:A kind of Novel chain unit, two pieces of outer plates including two pieces of inner plates just to setting and just to setting, and two pieces of inner plates are located between two pieces of outer plates, bearing pin is provided between inner plate described in two vertically, the connecting portion for being in the form of a column protrusion is respectively provided with the both ends of the surface of the bearing pin, and inner plate and outer plate with corresponding connecting portion axial restraint, cylindrical roller is cased with described bearing pin, it is characterized in that, bearing pin and connecting portion are in hollow form, and bearing pin and connecting portion are integral type structure, connecting portion described in two is respectively provided with internal thread, and internal thread is equal with the axial length of connecting portion along the length of connecting portion axial direction, it is bolted with the resistance to compression bar of solid direct rod shape in connecting portion described in two, and the external screw thread of resistance to compression bar is equal with the axial length of resistance to compression bar along the length of resistance to compression bar axial direction;The both ends of the surface of described resistance to compression bar are respectively positioned in same connecting portion, and the inner plate and outer plate that are connected with same connecting portion are respectively positioned between the both ends of the surface of resistance to compression bar.
Two pieces of inner plates and two pieces of outer plates are connected by same bearing pin, and the stress point distribution of inner plate, outer plate and bearing pin three is on the same line, enable this three of inner plate, outer plate and bearing pin while bearing and offsetting the active force suffered by chain, to effectively improve the compressive property of this chain unit, so as to extend the life-span of this chain unit.By setting bearing pin and connecting portion in hollow form, and resistance to compression bar is fully located in connecting portion, it is in filled circles column relative to whole bearing pin in the prior art, have the advantages that to mitigate weight chain, simultaneously because the stress point of chain is concentrated mainly on connecting portion with inner plate and the junction of outer plate, and side wall is bolted with connecting portion and is offseted with the connecting portion completely and in the resistance to compression bar of solid shape, and the inner plate that is connected with same connecting portion and outer plate are respectively positioned between the both ends of the surface of resistance to compression bar, so that resistance to compression bar plays preferable supporting role to above-mentioned stress concentrated position, to ensure the compressive property of above-mentioned stress concentrated position, so as to realize mitigating weight chain simultaneously, effective guarantee life-span of chain again.
In above-mentioned Novel chain unit, annular groove is offered on the madial wall of two-port on described roller, be equipped with the annular groove described in each
0
Type sealing ring one, and
0
The inner peripheral surface of type sealing ring one offsets with the side wall of bearing pin.
0
In the presence of type sealing ring one, so that the connection between roller and bearing pin keeps more reliable sealing, meanwhile, and because
0
Type sealing ring one is located at the port of roller, and the abrasion that roller inside increases roller and bearing pin is entered into so as to be prevented effectively from impurity, the service life of roller and bearing pin is then improve, further to improve the life-span of this chain unit.
In above-mentioned Novel chain unit, annular slot is equipped with the side wall of the resistance to compression bar described in every, is provided with described annular slot
0
Type sealing ring two, and
0
Madial wall of the outer peripheral face of type sealing ring two with connecting portion in port offsets.
Using above-mentioned structure, being entered by the junction of connecting portion and resistance to compression bar and accumulated in connecting portion being prevented effectively from the impurity such as dust increases the weight of connecting portion, so that the purpose stabilization for mitigating the weight of chain is realized.
In above-mentioned Novel chain unit, the end face on described resistance to compression bar away from bearing pin is the plane and end face is provided with socket.
When actually used, resistance to compression bar is screwed into connecting portion by particular tool.Usual instrument is in shaft-like, and its one end matches with socket, and has stopper on the side wall of the other end.When specifically used, to drive resistance to compression bar to screw in connecting portion in instrument one end insertion socket, when the end face of the stopper on instrument and connecting portion offsets, resistance to compression bar has reached specified location, now extracts instrument, has the advantages that easy to use.
Compared with prior art, this Novel chain unit has advantages below:
1
, two pieces of inner plates and two pieces of outer plates are connected by same bearing pin, and the stress point distribution of inner plate, outer plate and bearing pin three is on the same line, enable this three of inner plate, outer plate and bearing pin while bearing and offsetting the active force suffered by chain, to effectively improve the compressive property of this chain unit, so as to extend the life-span of this chain unit.
, by setting bearing pin and connecting portion in hollow form, and resistance to compression bar is fully located in connecting portion, it is in filled circles column relative to whole bearing pin in the prior art, have the advantages that to mitigate weight chain, simultaneously because the stress point of chain is concentrated mainly on connecting portion with inner plate and the junction of outer plate, and side wall is bolted with connecting portion and is offseted with the connecting portion completely and in the resistance to compression bar of solid shape, and the inner plate that is connected with same connecting portion and outer plate are respectively positioned between the both ends of the surface of resistance to compression bar, so that resistance to compression bar plays preferable supporting role to above-mentioned stress concentrated position, to ensure the compressive property of above-mentioned stress concentrated position, so as to realize mitigating weight chain simultaneously, effective guarantee life-span of chain again.
