Description
Technical field
the utility model belongs to the bearing pin relating to a kind of chain, particularly chain.
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 the bearing pin of chain, and technical problem to be solved in the utility model is the working life of how to improve chain.
the purpose of this utility model realizes by following technical proposal: the bearing pin of chain, comprise the body in solid direct rod shape, and the sidewall of body is cylndrical surface, it is characterized in that, it is circular self-lubricating layer that the two ends sidewall of described body is all fixed with one deck by the mode sintering or spray, the middle part sidewall of this body is provided with the oil storage tank in strip, and oil storage tank is arranged along the axis of body, described oil storage tank has two at least and circumference along body is uniform, described body axially offers the oil inlet hole in strip along it, oil inlet hole one end is closed, and the oil inlet hole the other end is positioned on a wherein end face of body, radial direction all along body on the diapire of the oil storage tank described in every bar offers the attachment hole be communicated with described oil inlet hole, the one-way mechanism flowing to one-way conduction making it along oil is provided with in described oil inlet hole, and one-way mechanism is between attachment hole and the aperture of oil inlet hole.
during oiling, grease enters in oil storage tank by oil inlet hole, attachment hole successively, to enter lubrication to the contacting point of body and axle sleeve, thus effectively reduces the wearing and tearing of bearing pin and axle sleeve, then improves the life-span of chain.By arranging the one-way mechanism flowing to one-way conduction making oil inlet hole along oil, all the time closed state is in when non-oiling to make the aperture of oil inlet hole, volatilized away by oil inlet hole effectively to avoid the grease being positioned at oil storage tank, thus extend the time of lubricating the contacting point of grease to axle sleeve and bearing pin, to improve the working life of chain further; Meanwhile, the process that aperture is closed is carried out automatically, has easy to operate advantage.By being all coated with in circular self-lubricating layer on the two ends sidewall of body, effectively to reduce the friction between body and outer plate, thus reducing the wearing and tearing of bearing pin and outer plate, then extending the life-span of chain further.
in the bearing pin of above-mentioned chain, described one-way mechanism comprises spring, steel ball and the pressure ring be all screwed onto in oil inlet hole and spring seat, described spring seat is between attachment hole and pressure ring, described steel ball is between pressure ring and spring seat, the two ends of described spring offset with spring seat and steel ball respectively, and under the action of the spring, steel ball and pressure ring offset and the inner chamber of pressure ring and attachment hole cut off, described spring seat runs through along the axis of pressure ring some oil outlets.
during oiling, when the oil pressure of lubricant oil is greater than the elastic force of spring, steel ball can make attachment hole and pressure ring inner space to the motion of attachment hole direction, and now, lubricant oil enters in oil storage tank by pressure ring inner chamber, oil outlet and attachment hole successively; When the oil pressure of lubricant oil is less than the elastic force of spring, steel ball automatically resets and to be cut off by the inner chamber of attachment hole and pressure ring under the elastic force effect of spring, to avoid the grease in oil storage tank to volatilize, has the advantage that working stability is high.
in the bearing pin of above-mentioned chain, the outer side wall of described pressure ring offers annular groove, in this annular groove, be provided with 0 RunddichtringO, and the madial wall of the outer circumferential face of 0 RunddichtringO and described oil inlet hole offsets.
under the effect of 0 RunddichtringO, seal more reliably to make to be formed between pressure ring and body, thus strengthen the difficulty that the grease that is positioned at oil storage tank volatilized by oil inlet hole further, thus further increase the working life of chain.
in the bearing pin of above-mentioned chain, described spring seat has protrusion and for the sheathed sleeved part of spring.
by arranging sleeved part, good position-limiting action being played to spring, making spring stably fore and aft motion occur, effectively to improve the working stability of one-way mechanism, thus the object of raising service life of chain is more stably realized.
alternatively, in the bearing pin of above-mentioned chain, described one-way mechanism comprises one-way valve, and the mode that the valve body of one-way valve is threaded connection is fixed in described oil inlet hole.
compared with prior art, the bearing pin of this chain has the following advantages:
1, by arranging multiple oil storage tank for storing grease on body sidewall, to enter lubrication to the contacting point of body and axle sleeve, thus effectively reducing the wearing and tearing of bearing pin and axle sleeve, then improving the life-span of chain.
, by arrange make oil inlet hole along oil the one-way mechanism flowing to one-way conduction, all the time closed state is in when non-oiling to make the aperture of oil inlet hole, volatilized away by oil inlet hole effectively to avoid the grease being positioned at oil storage tank, thus extend the time of lubricating the contacting point of grease to axle sleeve and bearing pin, to improve the working life of chain further; Meanwhile, the process that aperture is closed is carried out automatically, has easy to operate advantage.
, by being all coated with in circular self-lubricating layer on the two ends sidewall of body, effectively to reduce the friction between body and outer plate, thus reducing the wearing and tearing of bearing pin and outer plate, then extend the life-span of chain further.
