Abstract
The utility model discloses a kind of single-stage double-suction middle-opening pump bearing body linkage structure, comprise the pump housing, pump shaft, pump cover and bearing support, pump housing upper end is fixedly connected with pump cover, pump shaft is through the pump housing and pump cover, end is fixedly connected with bearing support, it is characterized in that corresponding bearing support bottom, described pump housing front end is provided with bearing bottom bracket, corresponding bearing top, described pump cover front end is provided with arc position shelf, described bearing support lower end and bearing bottom bracket are fixedly connected, upper end is fixedly connected with arc position shelf, described bearing bottom bracket both sides are respectively in " U " shape, the utility model is owing to adopting said structure, have rational in infrastructure, ensure bearing end levelness, operate steadily, easy to use, easy for installation, the advantages such as good heat dissipation effect.
Description
Technical field
The utility model relates to mechanical engineering pump technical field, specifically a kind of single-stage double-suction middle-opening pump bearing body linkage structure.
Background technique
At present, existing large-scale middle-opening pump be mostly bearing support and pump housing connecting end lower end through plane shape bracket support, bracket is connected with the pump housing.This structure can, due to the factor of gravity, make bracket produce certain deflection deformation, and amount of deflection crosses the vibrations that conference increases bearing end, affects the operation of pump, also reduces the working life of bearing support.And in the past due to belt bracket bearing support and pump housing connecting end belt bracket, mounting flange was comparatively large, caused bearing support too heavy, was not easy to install.
Summary of the invention
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provide a kind of rational in infrastructure, ensure bearing end levelness, operate steadily, the single-stage double-suction middle-opening pump bearing body linkage structure of easy to use, easy for installation, good heat dissipation effect.
The utility model solves the technological scheme that its technical problem adopts:
A kind of single-stage double-suction middle-opening pump bearing body linkage structure, comprise the pump housing, pump shaft, pump cover and bearing support, pump housing upper end is fixedly connected with pump cover, pump shaft is through the pump housing and pump cover, end is fixedly connected with bearing support, it is characterized in that corresponding bearing support bottom, described pump housing front end is provided with bearing bottom bracket, corresponding bearing top, described pump cover front end is provided with arc position shelf, described bearing support lower end and bearing bottom bracket are fixedly connected, upper end is fixedly connected with arc position shelf, described bearing bottom bracket both sides are respectively in " U " shape, two large windows are formed to make both sides, this large window is not only conducive to the installation of opening face bolt in shaft extension side, simultaneously, pump cover can be opened and directly change filler, and, also add bearing support and the pump housing, coupling stiffness between pump cover, effective reduction bearing support and the deflection deformation being connected bracket between the pump housing, reduce the vibrations of bearing end, alleviate the weight of bearing support, can install more easily.
Bearing bottom bracket lower end of the present invention is fixedly connected with the pump housing through strengthening gusset, is beneficial to the levelness ensureing bearing support further, reaches the effect operated steadily.
The utility model owing to adopting said structure, have rational in infrastructure, ensure bearing end levelness, operate steadily, the advantage such as easy to use, easy for installation, good heat dissipation effect.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Reference character: the pump housing 1, pump shaft 2, pump cover 3, bearing support 4, bearing bottom bracket 5, arc position shelf 6, reinforcement gusset 7.
Embodiment
Below in conjunction with specific embodiment, the utility model is further illustrated:
As shown in Figure 1, a kind of single-stage double-suction middle-opening pump bearing body linkage structure, comprise the pump housing 1, pump shaft 2, pump cover 3 and bearing support 4, the pump housing 1 upper end is fixedly connected with pump cover 3, pump shaft 2 is fixedly connected with bearing support 4 with pump cover 2 end through the pump housing 1, it is characterized in that corresponding bearing support 4 bottom, the described pump housing 1 front end is provided with bearing bottom bracket 5, corresponding bearing top, described pump cover 3 front end is provided with arc position shelf 6, described bearing support 4 lower end and bearing bottom bracket 5 are fixedly connected, upper end is fixedly connected with arc position shelf 6, described bearing bottom bracket both sides are respectively in " U " shape, two large windows are formed to make both sides, this large window is not only conducive to the installation of opening face bolt in shaft extension side, simultaneously, pump cover 3 can be opened and directly change filler, and, also add bearing support 4 and the pump housing 1, coupling stiffness between pump cover 3, effective reduction bearing support and the deflection deformation being connected bracket between the pump housing, reduce the vibrations of bearing end, alleviate the weight of bearing support, can install more easily.
Bearing bottom bracket 5 lower end of the present invention is fixedly connected with the pump housing 1 through strengthening gusset 7, is beneficial to the levelness ensureing bearing support further, reaches the effect operated steadily.
The utility model owing to adopting said structure, have rational in infrastructure, ensure bearing end levelness, operate steadily, the advantage such as easy to use, easy for installation, good heat dissipation effect.
