Description
Technical field
The present invention relates to a kind of chain, particularly a kind of chain unit.
Background technology
Chain is a kind of very common drive disk assembly, existing chain is substantially to be cascaded by a kind of a section chain unit, and a kind of chain unit is made up of two pieces of inner plates, two pieces of outer plates, axle sleeve, bearing pin, rollers etc., wherein, two pieces of inner plates are just fixed together to setting and by axle sleeve, two pieces of inner plates are respectively positioned between two pieces of outer plates and outer plate and inner plate position are relative, two pieces of outer plates are fixed together by bearing pin, and axle sleeve is set on bearing pin and roller sleeve is on axle sleeve.
In actual product, there is less gap between roller and axle sleeve and between bearing pin and axle sleeve, when chain is used under more muddy environment, soil can be easily advanced into above-mentioned gap, to increase the abrasion between roller, axle sleeve and bearing pin this three, the life-span of chain is then influenceed.
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 a kind of chain unit of long lifespan.
The purpose of the present invention can be realized by following technical proposal：A kind of 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, connecting pin is provided between two pieces of inner plates vertically, the connecting portion for being in the form of a column protrusion is respectively provided with the both ends of the surface of connecting pin, and inner plate and outer plate with corresponding connecting portion axial restraint, it is characterised in that connecting pin and connecting portion in solid shape and both pass through same material disposal molding；Cylindrical roller is cased with described connecting pin and the roller is located between two inner plates, roller is located on the madial wall at two-port and is equipped with annular groove, and two sealing rings are cased with connecting pin, and two sealing rings are respectively arranged in two annular grooves；The madial wall of pressure ring that is that there is protrusion on the inner edge of described sealing ring and being coaxial therewith, the axial length of the axial length less than sealing ring of pressure ring, and pressure ring and the side wall tight abutment of connecting pin.
Two pieces of inner plates and two pieces of outer plates are connected by same connecting pin, and inner plate, outer plate and connecting pin three distribution are on the same line, enable this three of inner plate, outer plate and connecting pin while bearing the active force suffered by chain, to effectively improve a kind of this compressive property of chain unit, so as to extend a kind of this life-span of chain unit.Meanwhile, and because connecting pin and connecting portion are in solid shape and both are integral type structure, to increase the compressive property of connecting pin, so as to further extend a kind of this life-span of chain unit.
Pressure ring
The side wall tight abutment of madial wall and connecting pin, make to form more reliable sealing between roller and connecting pin, avoid impurity between roller and connecting pin both are caused with abrasion, so as to extend the life-span of roller and connecting pin, then improve a kind of this life-span of chain unit；Simultaneously, further through axial length of the axial length less than sealing ring for setting pressure ring, on the premise of sealing effectiveness is ensured, reduce the contact area of sealing ring and connecting pin side wall, the active force to be applied when sealing ring is loaded so as to reduce, is then reduced when sealing ring is located at pretightning force suffered in roller, to reduce friction when roller is rotated suffered by pressure ring, the service life of sealing ring is improve, a kind of this service life of chain unit is then further extended.
In a kind of above-mentioned chain unit, the rectangular triangle in cross section of described pressure ring.
Using above-mentioned structure, further to reduce the contact area of pressure ring and connecting pin, so that the friction between pressure ring and connecting pin is reduced, to improve the life-span of sealing ring, so as to extend a kind of this service life of chain unit.
In a kind of above-mentioned chain unit, described pressure ring have two and both along sealing ring radial symmetric set, formed between the pressure ring described in two and offered on two side relative on oil storage tank annular in shape, and two pressure rings multiple conquassation grooves.
Connected with oil storage tank by setting conquassation groove and conquassation groove, pressure ring can be made more easily to deform upon, the active force to be applied when sealing ring is loaded with reducing, then reduce when sealing ring is located at pretightning force suffered in roller, so as to improve the service life of sealing ring, the ability that sealing ring stores lubricants capacity can be improved again, to extend the time that pressure ring and the contact position of connecting pin are subject to lubricate, so as to effectively extend the life-span of sealing ring, a kind of this service life of chain unit is then effectively extended.
In a kind of above-mentioned chain unit, through there is connecting hole on side wall relative with connecting portion on described outer plate, described connecting portion is located in connecting hole, and connecting portion is mutually fixed by way of interference fit with outer plate；There is tapered spigot surface on the madial wall of described connecting hole.
Using above-mentioned structure, so that connecting portion need not be to be capable of achieving the connection with outer plate by other parts, there is simple structure, a kind of weight of chain unit is reduced and easy for installation.
Compared with prior art, a kind of this chain unit has advantages below：
1
, two pieces of inner plates and two pieces of outer plates are connected by same connecting pin, and inner plate, outer plate and connecting pin three distribution are on the same line, enable this three of inner plate, outer plate and connecting pin while bearing the active force suffered by chain, to effectively improve a kind of this compressive property of chain unit, so as to extend a kind of this life-span of chain unit.Meanwhile, and because connecting pin and connecting portion are in solid shape and both are integral type structure, to increase the compressive property of connecting pin, so as to further extend a kind of this life-span of chain unit.
, pressure ring madial wall and the side wall tight abutment of connecting pin, make to form more reliable sealing between roller and connecting pin, avoid impurity between roller and connecting pin both are caused with abrasion, so as to extend the life-span of roller and connecting pin, then improve a kind of this life-span of chain unit；Simultaneously, further through axial length of the axial length less than sealing ring for setting pressure ring, on the premise of sealing effectiveness is ensured, reduce the contact area of sealing ring and connecting pin side wall, the active force to be applied when sealing ring is loaded so as to reduce, is then reduced when sealing ring is located at pretightning force suffered in roller, to reduce friction when roller is rotated suffered by pressure ring, the service life of sealing ring is improve, a kind of this service life of chain unit is then further extended.
, connected with oil storage tank by setting conquassation groove and conquassation groove, pressure ring can be made more easily to deform upon, the active force to be applied when sealing ring is loaded with reducing, then reduce when sealing ring is located at pretightning force suffered in roller, so as to improve the service life of sealing ring, the ability that sealing ring stores lubricants capacity can be improved again, to extend the time that pressure ring and the contact position of connecting pin are subject to lubricate, so as to effectively extend the life-span of sealing ring, a kind of this service life of chain unit is then effectively extended.
