CN 203997776 U]
It is sequentially connected with by chain link and constitutes, each chain link all includes outer plate, inner plate, roller, hollow pins and sleeve, outer plate and inner plate are sequentially arranged at the both sides of hollow pins, sleeve is arranged on the outside of hollow pins, roller sleeve is contained on sleeve, and described hollow pins uses medium carbon steel and carried out heat treatment.
In above-mentioned hollow pins chain, owing to hollow pins is cylindrically, operationally the two ends of hollow pins can be susceptible to deformation by the extruding of outer plate, affects hollow pins quality of fit between outer plate, cause transmitting procedure shakes relatively big, chain cisco unity malfunction.
Summary of the invention
It is an object of the invention to there are the problems referred to above for existing technology, it is proposed that a kind of service life length Novel hollow-pin chain bar.
The purpose of the present invention can be realized by following technical proposal: a kind of Novel hollow-pin chain bar, assembled by some groups of chain units, often organize described chain unit all include just to arrange two pieces of inner plates and two inner plates be fixed together by an axle sleeve, it is equipped with outer plate and two outer plates outside two inner plates to be fixed together by a bearing pin, described axle sleeve is set on bearing pin, described bearing pin is cylindrically, it is characterized in that, described bearing pin includes just to setting and two connecting pins the most cylindrically, two ends adjacent on two connecting pins are fixed together, every connecting pin all includes that the connecting portion one being positioned at described axle sleeve and the connecting portion two and each connecting portion two that are positioned at outside axle sleeve are all fixed together with corresponding outer plate, the internal diameter of described connecting portion two with the ratio of the internal diameter of connecting portion one is
3
Ratio

。
The internal diameter of connecting portion two is less than the internal diameter of connecting portion one, i.e. the wall thickness of connecting portion two is more than the wall thickness of connecting portion one, improve the pressure performance of connecting portion two, thus effectively reduce the probability that bearing pin two ends deform upon under the extruding of outer plate, to improve the service life of bearing pin, thus extend the service life of this hollow bearing pin chain；Meanwhile, the internal diameter of employing connecting portion two with the ratio of the internal diameter of connecting portion one is
3
Ratio
4
, while improving the pressure performance of connecting portion two, control the weight of connecting portion two so that this chain can stably work.Bearing pin is made up of two connecting pins being fixed together, and reduces difficulty when producing bearing pin, has advantage easy to process.
In above-mentioned Novel hollow-pin chain bar, have on the end face of one of them described connecting portion one protrusion and Plug Division cylindrically, it is correspondingly provided with annular groove on the end face of another described connecting portion one, described Plug Division is plugged in described annular groove, and on the connecting portion one described in two, adjacent end face sticks together and two connecting portions one are fixed together by weldering earthing mode.
The effect of pre-connection is played in Plug Division in being plugged on annular groove so that two connecting shafts by Primary Location when welding, facilitate the welding in later stage and improve the precision of welding.On two connecting portions one, adjacent end face sticks together, and adds the contact area of two connecting pins, thus improves fixing when two connecting shafts are fixed together, improves the service life of this hollow bearing pin chain.
In above-mentioned Novel hollow-pin chain bar, the thickness of described Plug Division is equal with the groove width of described annular groove.
I.e. when Plug Division is inserted in annular groove, the lateral wall of Plug Division and the medial wall of annular groove closely against together with, further increase the contact area of two connecting pins, thus improve fixing when two connecting shafts are fixed together, improve the service life of this hollow bearing pin chain.
In above-mentioned Novel hollow-pin chain bar, that the medial wall of described connecting portion two has a protrusion and reinforcement in strip and this reinforcement are arranged along the axial length direction of described bearing pin, the two ends of described reinforcement lay respectively in the both ends of the surface of connecting portion two, and the cross section of this reinforcement is that two sidewalls of triangular form and this reinforcement are middle part arc surface of depression inside this reinforcement.
Equal with the axial length of connecting portion two by arranging the length of reinforcement and this reinforcement, further increase the pressure performance of connecting portion two, thus effectively reduce the probability that bearing pin two ends deform upon under the extruding of outer plate, to improve the service life of bearing pin, thus extend the service life of this hollow bearing pin chain.
In above-mentioned Novel hollow-pin chain bar, described reinforcement has
3
Individual and be evenly distributed.
Compared with prior art, this Novel hollow-pin chain bar has the advantage that
