Abstract
The utility model discloses marine gear case bearing pedestal lower half with a sinking groove on the left side. A square base is arranged on the lower portion of a pedestal body. A semicircle is arranged inside the base. Outside edges protruding outwards are arranged on the left side and the right side of the upper end of the semicircle. A concave sinking groove is arranged on an upper surface of the outside edge on the left side. The sinking groove can be formed into a side hole with upper half of a bearing pedestal. A semicircle step with a shorter radius is arranged inside the semicircle. The pedestal body is cast through carbon steel pieces. Chemical components and mechanical properties of material accord with national standards specified in GB/T11352-89 cast carbon steel pieces used for general projects. By an additional structure of the semicircle step arranged inside the semicircle, the marine gear case bearing pedestal upper half with the sliding chutes arranged on the lower portion and the inside step can clamp a bearing tightly and prevent the bearing from loosening after long term use. At the same time, by an arrangement of the sinking groove on the outside edge, the sinking groove can be formed into the side hole with the upper half of the bearing pedestal, and therefore a countershaft can penetrate.
Description
Technical field:
The utility model relates to the bearing support field, relates in particular to the marine gearbox bearing support Lower Half that limit, a kind of left side has deep gouge.
Background technique:
The English by name bearing pedestal of bearing support or bearing housing are to be contained in to be used for the member of spring bearing on steam turbine body or the basis, also make spring bearing in marine gearbox.Bearing support in the past is ring design, and is loosening easily in the long-term situation about using after bearing clamps into, and marine gearbox main shaft limit also is provided with countershaft, and bearing support in the past has ground not pass for countershaft.Therefore imagination provides a kind of equipment to solve this problem.
The model utility content:
The purpose of this utility model just provides the marine gearbox bearing support Lower Half that limit, a kind of left side has deep gouge, the bearing support that solves in the past is the ring design, after bearing clamps into, loosening easily in the long-term situation about using, and marine gearbox main shaft limit also is provided with countershaft, the problem that bearing support does not in the past have ground to supply countershaft to pass.
The technical solution adopted in the utility model is:
Limit, a kind of left side has the marine gearbox bearing support Lower Half of deep gouge: the pedestal lower end is plinth, the base middle part has semi-circle, the left and right sides, semi-circle upper end has outwardly directed outer edge, the outer edge upper surface on the left side has recessed deep gouge, deep gouge can consist of lateral orifices with the bearing support first half, has the less semicircular arc step of radius in the semi-circle.
Described pedestal adopts the carbon-steel parts casting to form, and the chemical composition of material and mechanical property meet GB/T11352-89 " common engineering is with casting carbon-steel parts " NBS.
Compared with prior art, the beneficial effects of the utility model are:
The utility model can effectively tighten bearing by add the structure of a semi-circle step in semi-circle, prevents from using for a long time the loosening situation of rear bearing to occur; Simultaneously at the edge deep gouge is set, deep gouge can consist of lateral orifices with the bearing support first half, can pass for countershaft.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing, by embodiment the utility model is described in further detail:
Limit, a kind of left side has the marine gearbox bearing support Lower Half of deep gouge: pedestal 1 lower end is plinth 2, the base middle part has semi-circle 3, the left and right sides, semi-circle 3 upper end has outwardly directed outer edge 4, the outer edge upper surface on the left side has recessed deep gouge 5, deep gouge 5 can consist of lateral orifices with the bearing support first half, has the less semicircular arc step 6 of radius in the semi-circle 3, pedestal 1 adopts the carbon-steel parts casting to form, and the chemical composition of material and mechanical property meet GB/T11352-89 " common engineering is with casting carbon-steel parts " NBS.
Above-described embodiment only is better mode of execution of the present utility model, and in addition, the utility model can also have other implementations.Need to prove that under the prerequisite that does not break away from the utility model design, any apparent improvement and modification all should fall within the protection domain of the present utility model.
