Abstract
The utility model relates to a prestressed elastic positioning sleeve. The utility model has the main structure that on the basis of the traditional elastic positioning sleeve composed of an inner steel sleeve, an outer steel sleeve, and an elastic rubber, a lining board is additionally arranged between the outer edge of the elastic rubber and the inner edge of the elastic steel sleeve; the natural outer diameter of the elastic rubber is properly enlarged. The utility model has the advantages that the structural design is reasonable, the prestress is moderate, the tensile stress formed by the rubber vulcanization constriction can be effectively overcome, the tensile stress generated by the displacement of the inner steel sleeve and the outer steel sleeve can be overcome when the sleeve is used, the elastic rubber is not easy to separate from the steel sleeves, the mechanical property is good, the utility model is durable, etc. The utility model is a new generation product of the existing ordinary elastic positioning sleeve, and the utility model is suitable for being widely used on the train.
Description
The utility model relates to a kind of elastic locating sleeve that is installed on the train bogie truck, belongs to the accessory in addition of rolling stock.
The elastic locating sleeve of installing on the train bogie truck, mainly be by interior steel bushing at present, outer steel sleeve and elastic caoutchouc are formed, elastic locating sleeve is as the element of axle box vertical and horizontal location usefulness, be installed on the end of bogie truck spring guide pillar, form friction piece with the friction sleeve on the positioning seat, play location and cushioning effect, but the phenomenon that rubber and steel bushing bonding plane come unstuck and damage can appear in existing elastic locating sleeve in long-time running is used, research by analysis, its reason mainly is when passenger vehicle needs emergency braking in operational process, wheel is by locking, train slides on rail because of inertia, at this moment, will on elastic locating sleeve, produce the radial weight of about 15KN for a passenger vehicle railway carriage of saving 18 tons of weights, make elastic locating sleeve in, produce the side-play amount of the 3mm that has an appointment between the outer steel sleeve, make rubber one side of elastic locating sleeve be compressed 3mm, the opposite side 3mm that is stretched, the side that stretches is added the drawing stress of shrinking generation naturally after the vulcanization of rubber, is the major cause that makes rubber and steel bushing bonding plane come unstuck and destroy.
The purpose of this utility model is in order to overcome the weak point that above-mentioned existing elastic locating sleeve is easy to generate rubber and steel bushing disengaging, designing a kind of elastic caoutchouc is difficult for breaking away from steel bushing, good mechanical property, durable in use, the prestress elastic locating sleeve with the drawing stress of presetting.
Prestress elastic locating sleeve of the present utility model mainly is on the existing basis that comprises the elastic locating sleeve that interior steel bushing, outer steel sleeve and elastic caoutchouc are formed, increasing has sleeve plate, described sleeve plate is contained between elastic caoutchouc outer rim and the outer steel sleeve inner edge, and the external diameter of elastic caoutchouc is suitably strengthened.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 and accompanying drawing 3 are elastic caoutchouc deployed configuration scheme drawings.
Referring to accompanying drawing 1, among the figure 1 is outer steel sleeve, the 2nd, sleeve plate, the 3rd, elastic caoutchouc, the 4th, interior steel bushing, the drawing stress that presets for elastic caoutchouc is had, during design with the natural external diameter of elastic caoutchouc before being pressed into outer steel sleeve than the big 3-10mm of compression external diameter that is pressed in the outer steel sleeve, for the ease of being pressed into, can on elastic caoutchouc, have vertical arrow groove.Fig. 2 and Fig. 3 are the deployed configuration scheme drawing of elastic caoutchouc 3 before being pressed into outer steel sleeve, and 5 among the figure is vertical arrow grooves, and vertically the quantity of arrow groove can equal also can be not equal to the quantity of sleeve plate.During production, interior steel bushing 4 and elastic caoutchouc 3 and sleeve plate 2 can be done earlier and be in the same place, and then be fitted in the outer steel sleeve 1 and get final product.
The utlity model has reasonable in design, prestressing force is moderate, can effectively overcome the vulcanization of rubber and shrink And the tensile stress that forms, also can overcome in use in outer steel sleeve displacement and the tensile stress that produces makes bullet The property rubber be difficult for breaking away from steel bushing, good mechanical property and the advantage such as durable in use are existing ordinary elasticity location The renewal product of cover is adapted at being extensive use of on the train bogie.
Claims (2)
1. a prestress elastic locating sleeve comprises interior steel bushing, outer steel sleeve and elastic caoutchouc, it is characterized in that also including sleeve plate, and described sleeve plate is contained between elastic caoutchouc outer rim and the outer steel sleeve inner edge, and the external diameter of elastic caoutchouc is suitably strengthened.
2. prestress elastic locating sleeve as claimed in claim 1, the natural external diameter that it is characterized in that elastic caoutchouc has vertical arrow groove than the big 3-10mm of compression external diameter on the elastic caoutchouc.
