Description
Technical field
The utility model relates to a kind of wheel flange lubricating rod, specifically, is a kind of lubricated mushy stage built-up rim lubricating rod of railway locomotive, subway and city rail vehicle wheel rim that is used for.
Background technology
Railway locomotive, subway and city rail vehicle wheel rim when operation all the time with the rail contact friction, all there are wearing and tearing in wheel rim and rail, especially at the little running section of track curvature radius, because action of centrifugal force, it is more serious to wear and tear, and makes wheel and rail shortening in service life.In addition, at the little running section of track curvature radius, when contacting with rail, vehicle wheel rim also produces ear-piercing noise.In order to solve wearing and tearing and noise problem, the main at present method that adopts is the dry type wheel flange lubricating rod, because the lubricating film adhesive ability that produces when dry type wheel flange lubricating rod and wheel rim contact friction is little, be difficult to form complete lubricating film at wheel rim, cause wheel rim lubricated inhomogeneous, cause the wearing and tearing of wheel rim and dry type wheel flange lubricating rod big.Shortcoming at the dry type wheel flange lubricating rod, Chinese patent literature CN201023482Y has proposed a kind of rail vehicles wheel rim solid lubrication slide block, the solid lubrication slide block of this utility model is the graphite manufacturing, wherein a side end face of slide block is provided with slot, the opposite side end face is provided with the graphite plug tenon of making one with graphite slider, the direction of the inner end surface upper edge graphite plug tenon of slot is drilled with interior shoulder through hole, injects grease and form the grease oil column in interior shoulder through hole.Owing to be provided with the interior shoulder through hole that is marked with grease in the lubricated piece of this utility model, make and to lubricate piece the time with the wheel rim contact friction, grease in remaining in the half the circumference of the sleeve where it joins the shoulder through hole forms under the effect of friction heat and dissolves state and expand and separate out, thereby on the friction face of wheel rim, form lubricating film, this is with respect to the dry type wheel flange lubricating rod, can strengthen the lubricated of wheel rim, reduce the wearing and tearing between wheel rim and the lubricated piece, thereby reduce the wheel rim curve resistance, improve the locomotive tractive effort, prolong the service life of wheel.But still there are the following problems in actual use: in the lubricated piece of this utility model, consider the mechanical strength of lubricated piece itself and the factors such as volume size of lubricated piece itself, the setting of the number of the interior shoulder through hole in the lubricated piece is limited, grease in interior shoulder through hole is because of the effect of friction heat, expand when separating out to lubricated piece friction face from interior half the circumference of the sleeve where it joins the shoulder through hole, because thereby the spacing between adjacent two interior half the circumference of the sleeve where it joins the shoulder through holes is often separated out the size of the lubricating film that form to lubricated piece friction face greater than grease in interior half the circumference of the sleeve where it joins the shoulder through hole, make between adjacent two interior half the circumference of the sleeve where it joins the shoulder through holes and to be difficult for forming lubricating film on the pairing friction face of centre portion at interval, thereby being interrupted appears in the lubricating film that causes sticking on the whole wheel rim friction face, imperfect, cause the wheel rim place lubricated inhomogeneous thus, the bigger problem of loss between wheel rim and the lubricated piece.Moreover, when locomotive stops, in can not returning, the grease that molten condition is separated out in the half the circumference of the sleeve where it joins the shoulder through hole, causes the bigger waste of grease.
The utility model content
For this reason, technical problem to be solved in the utility model is that rail vehicles wheel rim solid lubrication slide block of the prior art can not form complete lubricating film and cause the lubricated uneven problem in wheel rim place, and providing a kind of can lubricate uniform wheel flange lubricating rod to the wheel rim place.
For solving the problems of the technologies described above, a kind of wheel flange lubricating rod of the present utility model, comprise the base rod, have on the described basic rod and to cooperate with the friction face of wheel rim, and to the lubricated basic excellent friction face of the described friction face of described wheel rim, be provided with in the described basic rod along the capillary tub on the length direction of described base rod, be provided with semisolid lubricants in the described capillary tub, and the distribution of described capillary tub in described base rod, the described semisolid lubricants of the feasible molten condition of separating out from adjacent two nearest described capillary tubs, the lubricating film that forms on the excellent friction face of described base can be bonded with each other or cover mutually.
Above-mentioned wheel flange lubricating rod, described semisolid lubricants is arranged in the described capillary tub by dipping.
Above-mentioned wheel flange lubricating rod, along on the length direction of described base rod, an end of described base rod forms groove, and the other end of described base rod forms the boss that is fit to insert described groove.
Above-mentioned wheel flange lubricating rod, the described cylindrical square or polygon irregular shape that is shaped as capillaceous.
Technique scheme of the present utility model has the following advantages compared to existing technology, in wheel flange lubricating rod of the present utility model, setting capillaceous and the capillary tub special distribution in the base rod, not only make when stopping, dissolve the semisolid lubricants of state, can under the effect of capillary force, remain in the capillary tub, thereby prevented the waste of semisolid lubricants, the more important thing is, linear expansion factor is greater than the semisolid lubricants of base rod, under the effect of the friction heat that when wheel flange lubricating rod and wheel rim friction, produces, in the capillary tub when the excellent friction face of base shifts, because the special distribution of capillary tub in the base rod, make and on the excellent friction face of base, to form by the semisolid lubricants that from each capillary tub, shifts complete to the excellent friction face of base, lubricated good, firm attachment and the lubricated transfer membrane of the semisolid that evenly covers.And along with the carrying out of the friction of wheel flange lubricating rod and wheel rim, the semisolid lubricants in the capillary tub constantly is provided in friction face, forms continuous lubricating film on wheel rim, when having guaranteed long-time running, to the good lubrication of friction pair.
