Abstract
The utility model relates to a kind of valve gear axle box bearing stand structure.Current valve gear box structure, the tensile strength of bearing support is lower, and bearing support, bearing guard position are easy to be worn, and when under the using state in high strength, is easy to the damage causing gear-box.The utility model comprises a bearing support be made up of steel matter, it is characterized in that, the Stem Mut be made up of copper material that is threaded is adopted in described bearing support, the outer end of described Stem Mut has one to be pressed on gland in bearing support, and described gland is positioned at bearing support and adopts screw thread to be connected with bearing support.The utility model adopts bearing support with Stem Mut split, again by the structure that both are firmly connected by gland, realizes the object that Stem Mut is separated with bearing support material, improves the tensile strength of bearing support, extends the working life of valve.
Description
Technical field
The utility model relates to valve gear roller box field, specifically a kind of valve gear axle box bearing stand structure.
Background technique
Current valve gear box structure, its bearing support and copper nut are structure as a whole, namely the material of bearing support is also copper, because the tensile strength of copper is lower, bearing support, bearing guard position are easy to be worn, when under the using state in high strength, be easy to the damage causing gear-box, thus affect the working life of valve.
Model utility content
Technical problem to be solved in the utility model is the defect overcoming the existence of above-mentioned prior art, provides the valve gear axle box bearing stand structure that a kind of Stem Mut is separated with bearing support material, to improve the tensile strength of bearing support, thus extends the working life of valve.
For this reason, the utility model adopts following technological scheme: valve gear axle box bearing stand structure, comprise a bearing support be made up of steel matter, it is characterized in that, the Stem Mut be made up of copper material that is threaded is adopted in described bearing support, the outer end of described Stem Mut has one to be pressed on gland in bearing support, and described gland is positioned at bearing support and adopts screw thread to be connected with bearing support.
The utility model adopts bearing support and Stem Mut split, again by structure that both are firmly connected by gland, thus realize the object that Stem Mut is separated with bearing support material, the material of bearing support is made to adopt steel, tensile strength is higher than copper by about 10%, although add difficulty of processing and cost, but improve the tensile strength of bearing support, the working life of valve reaches original 1.5 times.
Further, described gland, bearing support and Stem Mut adopt a Cock screw to be connected, and prevent gland and Stem Mut from coming off from bearing support.
Further, the hand of spiral on described gland is contrary with the hand of spiral on Stem Mut, prevents gland from coming off.
Further, in the gland end of conflicting with Stem Mut, outside all forms chamfering structure, increase gland junction surface place both when screwing to lifting force.
Further, the end that described gland is connected with bearing support adopts electric welding, effectively prevents coming off of gland.
The beneficial effect that the utility model has: the utility model adopts bearing support and Stem Mut split, again by structure that both are firmly connected by gland, realize the object that Stem Mut is separated with bearing support material, improve the tensile strength of bearing support, extend the working life of valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-bearing support, 2-Stem Mut, 3-gland, 4-Cock screw, 5-bearing.
Embodiment
Below in conjunction with embodiment and Figure of description, the utility model is further described.
Valve gear axle box bearing stand structure as shown in Figure 1, the Stem Mut 2 be made up of copper material that is threaded is adopted in the bearing support 1 be made up of steel matter, the outer end of Stem Mut 2 is provided with the gland 3 be pressed in bearing support, and gland 3 is positioned at bearing support and adopts screw thread to be connected with bearing support 1.Bearing support 1 is equipped with bearing 5.
Described gland 3, bearing support 1 and Stem Mut 2 adopt Cock screw 4 to be connected, and the hand of spiral on gland 3 is contrary with the hand of spiral on Stem Mut 2.In the gland end of conflicting with Stem Mut, outside all forms chamfering structure, and the end that gland 3 is connected with bearing support 1 adopts electric welding.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change.All various changes done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
