Description
Technical field
The present invention relates to a kind of three support-secondary framework separation type bearing saddle assemblies that are used for the radial steering 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 Fig. 4, shown in Figure 5, existing radial steering railway truck bearing saddle assembly adopts the double bracing form, and its formation is: interior support 3 and support outward 4 bogie side frame and adapter 5 ' between, be fastenedly connected with bogie side frame 1 below and adapter 5 ' top corresponding position.Adapter 5 ' bottom with bearing 6 outer ring contact matching.Fig. 5 illustrates, adapter 5 ' with secondary framework 7 ' be integrated, also promptly two bogie side frames with two adapters 5 of end (front end or rear end) ' with secondary framework 7 ' integrally manufactured, becoming one structure.The power that side frames 1 transmits is divided into two parts by inside and outside support 3,4, passes to adapter-secondary framework-adapter integral structure and bearing.
As shown in Figure 6, the bearing saddle assembly of existing double bracing form makes bearing 5 outer rings the higher local contact fatigue stress in two places occur, thereby two place's bearing rollers " the plug resistance of rolling " effect occurs, and bearing is reduced service life.
Simultaneously, adapter-secondary framework-adapter integrative-structure increased both sides adapter 5 ' the difficulty of right alignment processing and assembling, cause adapter 5 ' contact easily with bearing 6 outer ring fitting surfaces are local, the local contact fatigue stress of outside race is increased, also reduced bearing life, increased the difficulty of site assembly, maintenance, thereby processing, assembling and maintenance cost are increased.
Summary of the invention
The purpose of this invention is to provide a kind of three support-secondary framework separation type bearing saddle assemblies of radial steering railway truck, this kind bearing saddle assembly can make the outside race stand under load even, and local stress is low, prolongs bearing life; And its processing, assembling, on site maintenance are convenient, and processing, assembling, maintenance cost are low.
The present invention realizes that the technical scheme that purpose adopted of its invention is: a kind of radial steering railway truck three support-secondary framework separation type bearing saddle assemblies, comprise the interior support of bogie side frame below, the outer support, interior adapter, the intrados of adapter and the outside race contact matching that supports, supports the below outward.Its constructional feature is, supports in also having between interior support, the outer support, and the top of middle support links to each other with bogie side frame is fastening, and the bottom is fastenedly connected by secondary framework connecting panel and adapter, and secondary framework connecting panel and secondary framework are fastenedly connected or are integrated.
Compared with prior art, the invention has the beneficial effects as follows:
The power that bogie side frame is passed to adapter and bearing is divided into three parts by three supports, stressed more even, and the stressed of three supports can design distribution according to the principle of even outside race contact fatigue stress, under the mechanics principle that satisfies the bogie side frame compatibility of deformation, by allocating the vertical and lateral stiffness of each propping material, the realization outside race is stressed to be reached farthest evenly.The local stress of outside race diminishes, and has reduced roller " the plug resistance of rolling " effect, the fatigue life of having improved bearing.
Fig. 3 is the distribution schematic diagram of the circumferential contact fatigue stress of outside race of the present invention.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, reduced roller " the plug resistance of rolling " effect.
Simultaneously, secondary framework-the bearing saddle assembly of this separation type, incorporate secondary framework bearing saddle assembly than prior processing, fundamentally eliminate secondary framework both sides adapter and needed in advance the accurately problem of right alignment processing and assembling, the difficulty of its processing, assembling, maintenance reduces greatly, only the adapter of both sides need be alignd with secondary framework connecting panel after coaxial, the equidistant requirement of realization, fix getting final product again.Site assembly and maintenance, processing are extremely convenient, have reduced processing, assembling, maintenance cost.
Above-mentioned middle support, interior support, support outward by last liner plate, the elastomeric material between liner plate and two liner plates is formed by stacking down; Middle support, interior support, the outer support all are fastenedly connected by last liner plate and bogie side frame bottom corresponding site; Interior support, support outward are fastenedly connected by following liner plate and adapter relevant position, and secondary framework connecting panel and adapter relevant position under middle support reaches by following liner plate below the liner plate are fastenedly connected.
Interior, the domestic and abroad support of this structure both made bogie side frame easy for installation with adapter, be connected firm, power transmission is reliable; When supporting in the installation, also easily secondary framework and adapter are connected and fixed by secondary framework connecting panel; Elastomeric material between stay bearing plate has also alleviated the vibratory impulse between adapter and outside race, has further improved the service life of bearing; And the allotment of the vertical and lateral stiffness of elastomeric material is also convenient, easy, can allocate the vertical and lateral stiffness that each supports more easily, realizes that outside race is stressed evenly.
Below in conjunction with the drawings and specific embodiments the present invention is done a step explanation.
