Abstract
本发明公开了一种铁路货车三支撑承载鞍组件，含有侧架1导筐1a内的支撑2及支撑2下方的承载鞍5，承载鞍5的内弧面与轴承6外圈接触配合，其特征在于：所述的侧架1导筐1a两端的下部还通过内支撑3和外支撑4分别与承载鞍5的内、外两端上部相连。该种承载鞍组件能使轴承外圈接触疲劳应力均匀，降低局部应力，延长轴承寿命。
The invention discloses a three-support bearing saddle assembly for a railway freight car, which includes a support 2 inside a guide basket 1a of a side frame 1 and a bearing saddle 5 below the support 2. The inner arc surface of the bearing saddle 5 contacts and cooperates with the outer ring of a bearing 6. The feature is that the lower parts of the two ends of the guide basket 1a of the side frame 1 are also connected to the upper parts of the inner and outer ends of the bearing saddle 5 through the inner support 3 and the outer support 4 respectively. The bearing saddle component can make the contact fatigue stress of the outer ring of the bearing uniform, reduce the local stress, and prolong the service life of the bearing.
Description
Technical field
The present invention relates to a kind of three-support bearing saddle assembly that is used for railway truck.
Background technology
Two bogie side frames are arranged in the freight train bogie truck, and the rear and front end of a bogie side frame is installed bearing saddle assembly respectively, links to each other with the bearing of wheel shaft by bearing saddle assembly.Also promptly, bearing saddle assembly is the power transmission assembly that connects bogie side frame and bearing in the freight train bogie truck.As shown in Figure 3, the formation of existing railway truck bearing saddle assembly is: one is supported 2 ' is positioned at basket 1a ' that leads of bogie side frame 1 ' below, by last liner plate A ' and bogie side frame 1 ' lead a basket 1a ' top corresponding position to be fastenedly connected, be fastenedly connected with adapter 5 ' center top position by liner plate B ' down.Adapter 5 ' intrados and outside race contact matching, the power that bogie side frame transmits with concentrated form by supporting 2 ' passing to adapter 5 ' and bearing 6.As shown in Figure 4, the maximum contact fatigue stress appears near top, bearing 6 outer ring and stress level higher, thereby bigger bearing roller " the plug resistance of rolling " effect appears near the top.In a word, the bearing saddle assembly of existing freight train makes outside race contact fatigue unbalanced stress even, has local area of high stress, has reduced bearing life.
Summary of the invention
The purpose of this invention is to provide a kind of three-support bearing saddle assembly that is used for railway truck, this kind bearing saddle assembly can make outside race contact fatigue stress even, reduces local stress, prolongs bearing life.
The present invention realizes that the technical scheme that purpose adopted of its invention is: a kind of railway truck three-support bearing saddle assembly, contain the adapter that bogie side frame is led the support in the basket and supported the below, the intrados of adapter and outside race contact matching is characterized in that: the bottom that described bogie side frame is led basket two ends also links to each other with the top, inside and outside two ends of adapter respectively with outer the support by interior support.
Compared with prior art, the invention has the beneficial effects as follows:
The power of bogie side frame being passed to adapter and bearing is divided into three parts by three supports, the big I of each several part power is according to the needs of even outside race contact fatigue stress, under the mechanics principle that satisfies the bogie side frame compatibility of deformation, realize by the vertical and lateral stiffness of allocating each support, thereby uniformization ground power transmission makes outside race contact fatigue stress even to adapter and outside race, reduces local stress, reduce roller " the plug resistance of rolling " effect, prolonged bearing life.
Fig. 2 is the circumferential contact fatigue distribution of stress of an outside race of the present invention scheme drawing.Find out also that from this figure the present invention makes outside race upper axial contact fatigue distribution of stress even, does not have the fatigue stress centrostigma.
Above-mentioned support, interior support, support outward by last liner plate, the elastomeric material between liner plate and two liner plates is formed by stacking down, support, interior support, the outer support all are fastenedly connected by last liner plate and bogie side frame bottom corresponding site, by liner plate and adapter relevant position are fastenedly connected down.
Three kinds of supports of this structure both made bogie side frame easy for installation with adapter, be connected firm, power transmission is reliable, the elastomeric material between two faggings has also alleviated the vibratory impulse between adapter and outside race, the service life of further having improved bearing simultaneously.And, elastomeric material vertical and allotment lateral stiffness also be more prone to, can allocate the vertical and lateral stiffness that each supports more easily, realize that outside race is stressed evenly.
Below in conjunction with the drawings and specific embodiments the present invention is done a step explanation.
Description of drawings
Fig. 1 is the disintegration structural representation of the embodiment of the invention.
Fig. 2 is the circumferential contact fatigue stress system of outside race of the present invention that calculates with finite element method.
Fig. 3 is the disintegration structural representation of existing truck carrying adapter component.
Fig. 4 is the circumferential contact fatigue stress system of outside race that produces with the existing truck carrying adapter component that finite element method calculates.
Specific implementation method:
Fig. 1 illustrates, and a kind of specific embodiment of the present invention is:
A kind of railway truck three-support bearing saddle assembly contains adapter 5, the intrados of adapter 5 and bearing 6 outer ring contact matching that bogie side frame 1 is led the support 2 in basket 1a and supported 2 belows.The bottom that bogie side frame 1 is led basket 1a ' two ends also links to each other with the top, inside and outside two ends of adapter 5 respectively with outer support 4 by interior support 3.Support 2, interior support 3, support 4 by last liner plate outward, the elastomeric material C between liner plate and two liner plates is formed by stacking down, support 2, interior support 3, support 4 outward and all be fastenedly connected, be fastenedly connected by descending liner plate B and adapter 5 relevant positions to inlay by last liner plate A and bogie side frame 1 bottom corresponding site.
Be fastenedly connected and descend the liner plate B and being fastenedly connected of adapter 5 of last liner plate A of the present invention and bogie side frame 1 can be adopted the various existing modes that are fastenedly connected.As realizing that by inlaying auxiliary connection establish a shrinkage pool on last liner plate A, and at the correspondence position of bogie side frame 1 projection is set, the shrinkage pool of this projection and last liner plate closely cooperates; Following liner plate B is provided with projection, and at the correspondence position of adapter 5 shrinkage pool is set, and projection closely cooperates with shrinkage pool.Also can adopt the screw threads for fastening connection mode.Also can realize fastening with going up liner plate A and bogie side frame 1, following liner plate B and adapter 5 welding.
Fig. 2 illustrates, pass through three support and connection between adapter 5 of the present invention and the bogie side frame, the power that three supports are passed to adapter 5 and bearing 6 with bogie side frame is divided into three parts, the size of each several part power is according to the needs of even bearing 6 outer ring contact fatigue stress, under the mechanics principle that satisfies bogie side frame 1 compatibility of deformation, realize by the vertical and lateral stiffness of allocating elasticity material C in each support, thereby the fatigue stress of bearing 6 outer rings is evenly distributed, eliminate " the plug resistance of rolling " effect, improve bearing life.
