Abstract

The utility model relates to a gearbox body comprising a main body of the gearbox body, wherein a bearing hole is formed in the main body of the gearbox body, at least one through hole is formed in the main body of the gearbox body, a connecting line of the centre of the first through hole and the centre of the bearing hole is arranged to form an angle of minus 30 degrees to minus 60 degrees or minus 120 degrees to 160 degrees with the horizontal line, and the central distance between the centre of the first through hole and the centre of the bearing hole is 80-90mm; and the gearbox body provided by the utility model has the advantages that the first through holes are respectively formed in the box body, so that oil in the box body is discharged through the first through holes after the box body is assembled to avoid the oil leakage phenomenon on the box body, the structure is simple, the application effect is improved, and the production quality is improved as well.

Description

A kind of gear box
Technical field
The utility model relates to a kind of gear box.
Background technique
Casing is the important composition parts of gearbox, it is the pedestal of driving parts, as shown in Figure 1: casing body 1 is provided with bearing hole 11, and on the bearing hole without spill port, casing exists casing and bearing cap joint oil sealing oil leakage phenomenon after assembling is finished like this, and using effect is poor, anti-revisionist troublesome poeration, manufacturing efficiency is low.
The model utility content
The technical problems to be solved in the utility model is that existing casing exists oil leakage phenomenon, and using effect is poor, thereby a kind of gear box is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of gear box, comprise the casing body, described casing body is provided with bearing hole, described casing body is provided with at least one first through hole, the center of described the first through hole becomes-30 °~-60 ° or-120 ° of-160 ° of angles settings with bearing hole center connecting line with horizontal line, the centre distance at the center of described the first through hole and bearing hole center is 80-90mm.
Preferably, described casing body is provided with two the first through holes, the center of described two the first through holes becomes respectively-45 ° and-140 ° of angles settings with bearing hole center connecting line and horizontal line angle, the centre distance at the center of described the first through hole and bearing hole center is 84mm, simple in structure, using effect is good.
Preferably, described the first through hole is circular hole, also can be other results of being convenient to process, and borehole structure is simple, and is easy to process, easy to use.
In sum, advantage of the present utility model: by being respectively equipped with the first through hole on the casing, after the casing assembling, the oil in the casing is discharged by the first through hole hole, has avoided that oil leakage phenomenon is arranged on the casing, and is simple in structure, improved using effect, and the quality of production also improves.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of existing a kind of gear box;
Fig. 2 is the structural representation of the utility model gear box.
Embodiment
As shown in Figure 2, a kind of gear box, comprise casing body 1, described casing body 1 is provided with bearing hole 11, described casing body 1 is provided with at least one first through hole 2, the center of described the first through hole 2 becomes-30 °~-60 ° or-120 ° of-160 ° of angles settings with bearing hole 11 center connecting lines with horizontal line, the centre distance at the center of described the first through hole 2 and bearing hole 11 centers is 80-90mm, described casing body 1 is provided with two the first through holes 2, the center of described two the first through holes 2 becomes respectively-45 ° and-140 ° of angles settings with bearing hole 11 center connecting lines and horizontal line angle, the centre distance at the center of described the first through hole 2 and bearing hole 11 centers is 84mm, simple in structure, using effect is good, and is simple in structure, using effect is good, described the first through hole 2 is circular hole, also can be other results of being convenient to process, and borehole structure is simple, easy to process, easy to use.
Become respectively-45 ° and-140 ° of angles to be arranged on the casing body 1 line of two the first through holes 2 and bearing hole 11 and horizontal angle, then with casing body 1 respectively with bearing cap and bonnet installation after, discharge oil in the casing bodies 1 by the first through hole 2.
By being respectively equipped with the first through hole on the casing, after the casing assembling, the oil in the casing is discharged by the first through hole hole, has avoided that oil leakage phenomenon is arranged on the casing, and is simple in structure, improved using effect, and the quality of production also improves.
