Description
Technical field
The utility model relates to a kind of chain, particularly Novel chain bearing pin.
Background technique
Chain is a kind of very common transmission part, existing chain is cascaded by a section chain unit substantially, and chain unit is made up of two pieces of inner plates, two pieces of outer plates, axle sleeve, bearing pin, cylinders etc., wherein, two pieces of inner plates are just to arranging and being fixed together by axle sleeve, two pieces of inner plates are all between two pieces of outer plates and outer plate is relative with inner plate position, two pieces of outer plates are fixed together by bearing pin, and axle sleeve is set on bearing pin and roller sleeve is contained on axle sleeve.
In existing chain, lining and inner chain sheet form a combination, and this bearing pin and outer chain sheet link formation interlock body, and interlock body can bend relative to combination, and allowing this chain have whereby can the characteristic of bending.Because this chain is in the process of bending, the lining coaxially worn and bearing pin can be pivoted relative to each other and produce severe friction, therefore general chain can add lubricant oil in the bond sites of lining and bearing pin in use, to prevent inter-module excessive wear, makes it more smooth and easy in running.
But the outer circumferential face due to bearing pin is in the past a smooth surface, so when lubricant oil is added on the binding site of this chain, easily running off, it is loose to overflow, and lubrication effect is not easily lasting, often causes the quick abrasion of chain members and working life to shorten.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of Novel chain bearing pin that can extend service life of chain.

By arranging the lubrication groove for storing lubricant grease, the contacting point between bearing pin and axle sleeve directly being lubricated, effectively to reduce the wearing and tearing of bearing pin and axle sleeve, then improves the life-span of chain.Again by arranging the oil storage tank formed by the upper-end surface of annular convex shoulder, connecting rod sidewall and connecting cylinder madial wall three, and oil storage tank is also communicated with lubrication groove with oil duct respectively between oil duct and lubrication groove, to enable oil storage tank constantly for lubrication groove provides grease, thus extend further the time of lubricating the contacting point of grease to axle sleeve and bearing pin, then extend the life-span of chain further.By arranging 0 RunddichtringO one, make to be formed between annular convex shoulder and connecting rod to seal comparatively reliably, simultaneously again by arrange annular gear along the notch of oil storage tank is closed and annular gear along being integral type structure with connecting rod, thus effectively avoid the grease volatilization being positioned at oil storage tank, to extend the time that the contacting point of grease to axle sleeve and bearing pin is lubricated, then effectively extend the life-span of chain.
In above-mentioned Novel chain bearing pin, described attachment hole is strip and radial direction along connecting rod is arranged, and described attachment hole has two at least and axis along attachment hole is uniform.
By arranging multiple attachment hole, to increase the efficiency of oil storage tank for lubrication groove fuel feeding, thus effectively reducing the wearing and tearing of axle sleeve and bearing pin, then improve the life-span of this chain.
In above-mentioned Novel chain bearing pin, the upper-end surface of described connecting cylinder offers annular slot, in this annular slot, be inserted with sealing gasket in the form of a ring, and the both ends of the surface of sealing gasket are kept off along offseting with annular with the diapire of annular slot respectively.
Under the effect of sealing gasket, formed between annular gear edge and connecting cylinder and seal comparatively reliably, effectively to improve annular gear along the stability closed by the notch of oil storage tank, thus effectively strengthen the difficulty of grease volatilization, then make the object of prolongation service life of chain more stably realize.
Alternatively, in above-mentioned Novel chain bearing pin, the lower end surface on described annular gear edge has the sealed department protruded in the form of a ring, and sealed department and annular are kept off along coaxial; Described sealed department is plugged in connecting cylinder, and the outer side wall in sealing portion offers annular seal groove, is provided with 0 RunddichtringO two in described annular seal groove, and the outer circumferential face of 0 RunddichtringO two and the madial wall of connecting cylinder offset.
In above-mentioned Novel chain bearing pin, described annular gear is along being fixed by some bolts and described connecting cylinder.
When reality uses, due to connecting rod and connecting cylinder be from different component with the use of, cause connecting rod different with the degree of wear of connecting cylinder; And adopt above-mentioned structure, realize connecting rod and connecting cylinder is detachably fixed, thus realize changing separately connecting rod or connecting cylinder to reduce replacement cost.
Compared with prior art, this Novel chain bearing pin has the following advantages:
1, by arranging the lubrication groove for storing lubricant grease, the contacting point between bearing pin and axle sleeve directly being lubricated, effectively to reduce the wearing and tearing of bearing pin and axle sleeve, then improves the life-span of chain; Secondly again by arranging the oil storage tank formed by the upper-end surface of annular convex shoulder, connecting rod sidewall and connecting cylinder madial wall three, and oil storage tank is also communicated with lubrication groove with oil duct respectively between oil duct and lubrication groove, to enable oil storage tank constantly for lubrication groove provides grease, thus extend further the time of lubricating the contacting point of grease to axle sleeve and bearing pin, then extend the life-span of chain further.
2, by arranging 0 RunddichtringO one, make to be formed between annular convex shoulder and connecting rod to seal comparatively reliably, simultaneously again by arranging annular gear along being closed by the notch of oil storage tank, and annular gear along and connecting rod be integral type structure and annular keep off to be provided with between edge and connecting cylinder make both form the sealing gasket of reliable sealing, effectively to avoid the grease volatilization being positioned at oil storage tank, thus extend the time of lubricating the contacting point of grease to axle sleeve and bearing pin, then effectively extend the life-span of chain.
