Abstract
The utility model relates to a tumbler hoop for a bogie axle box of a high-speed train. The tumbler hoop is wholly and approximately to be in the shape of semi-circle, and the semi-circle is outwards opened by 1 degree to 2 degrees relative to the symmetrical centerline of the semi-circle. A clamping lug of the tumbler hoop is fixedly connected with a tumbler by a screw bolt at a connecting hole, two end parts of the outer edge of the tumbler hoop are connected with the tumbler in a clamping way, the tumbler hoop is wholly and outwards opened at a proper angle, and the opening angle of the tumbler hoop is disappeared or the opening angle of the tumbler hoop is the same as the inclined angle of the tumbler at an assembling part due to the elastic deformation of a metal material after the tumbler hoop is tightly clamped with the tumbler, so that a good seal effect can be achieved.
Description
Technical field
The utility model relates to high-speed train bogie axle box field, particularly a kind of high-speed train bogie axle box pivoted arm hoop.
Background technology
High-speed train bogie is the critical component that guarantees the train high-speed cruising, the application of bogie truck has not only improved the running velocity of passenger vehicle, has also satisfied the good curving performance of vehicle and the needs of traveling comfort simultaneously.The raising of train speed has proposed harsher requirement to high-speed train bogie.Axle box is one of critical component on the bogie truck, and the effect of axle box device is: will take turns linking together with bogie side frame or framework, and make wheel be converted into the translation on car body road along the line to the rolling along rail; Bear the weight of vehicle, transmit the application force of all directions; Guarantee good lubricating property, reduce abrasion, reduce running resistance, good sealing property prevents that things such as dust, rainwater from invading and get rid of oil, thereby avoids destroying the lubricated of grease, even accident such as fuel oil takes place.Axle box is divided into two types, and one type is the integral type axle box, and one type is split type axle box.Split type axle box is made up of journal box body, pivoted arm and hoop, because axle box is high to the requirement of leak tightness, and behind hoop and the pivoted arm chucking, all can produce deformation, has influenced sealing effectiveness.
The utility model content
The technical matters that the utility model will solve is: in order to overcome hoop and the affected deficiency of pivoted arm chucking back sealing effectiveness, the utility model provides a kind of high-speed train bogie axle box pivoted arm hoop.
The utility model solves the technical scheme that its technical matters adopted: a kind of high-speed train bogie axle box pivoted arm hoop, and integral body is semicircular in shape roughly, and the symmetrical center line of the relative semicircle of described semicircle is outwards opened 1 °～2 °.
The folder ear of pivoted arm hoop is captiveed joint the both ends of pivoted arm hoop outer rim and pivoted arm clamping in the connection hole through bolt with pivoted arm.Pivoted arm is processed by identical metallic material with the pivoted arm hoop, and metal can produce elastic deformation under certain condition, utilizes this specific character to make pivoted arm and pivoted arm hoop be able to assembling; The thickness of pivoted arm and structural strength all greater than the thickness and the structural strength of pivoted arm hoop, can access good leak tightness.
The beneficial effect of the utility model is; The utility model high-speed train bogie axle box pivoted arm hoop; Pivoted arm hoop integral body is outwards opened suitable angle, behind pivoted arm hoop and pivoted arm assembling chucking, because the elastic deformation of metallic material; The opening angle of pivoted arm hoop disappears or is identical at the angle of inclination of assembling place with pivoted arm, thereby reaches good sealing effectiveness.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the optimum embodiment of high-speed train bogie axle box pivoted arm hoop of the utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1 at the A place.
Among the figure 1, the folder ear, 11, connecting bore.
The specific embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the scheme drawing of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of high-speed train bogie axle box pivoted arm hoop, integral body is semicircular in shape roughly, and the semicircle symmetrical center line of semicircle is relatively outwards opened 1 °～2 °.Fig. 2 is the partial enlarged drawing of Fig. 1 at the A place, and α is the extended line of pivoted arm hoop end outer rim and the angle of vertical direction among the figure, and the angle of α is the half the of the whole opening angle of pivoted arm hoop.
The folder ear 1 of pivoted arm hoop is captiveed joint the both ends of pivoted arm hoop outer rim and pivoted arm clamping at connecting bore 11 places through bolt with pivoted arm.Pivoted arm is processed by identical metallic material with the pivoted arm hoop, and metal can produce elastic deformation under certain condition, utilizes this specific character to make pivoted arm and pivoted arm hoop be able to assembling; The thickness of pivoted arm and structural strength all greater than the thickness and the structural strength of pivoted arm hoop, can access good leak tightness.Pivoted arm hoop integral body is outwards opened suitable angle, and behind pivoted arm hoop and pivoted arm assembling chucking, because the elastic deformation of metallic material, the opening angle of pivoted arm hoop disappears or be identical at the angle of inclination of assembling place with pivoted arm, thereby reaches good sealing effectiveness.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification sheets, must confirm its technical scope according to the claim scope.
