Abstract
The utility model discloses a carrier gear shaft which comprises a body matched with a carrier gear. A first step face is arranged on one side of the body, a second step face is arranged on the other side of the body, and a third step face is arranged on the outer side of the first step face. A keyway is arranged in the longitudinal surface of the body and is communicated with the second step face. The side (of the keyway) close to the first step face is circular. The diameter of the first step face is greater than that of the body, while the diameter of the second step face is smaller than that of the body. For the carrier gear shaft with the design, as the concentricity is ensured and match of the carrier gear and the carrier gear shaft can be adjusted through the keyway, and vibration of the carrier gear to the carrier gear shaft in the rotating process can be reduced, so that the carrier gear shaft provided by the utility model is simple in structure, high in strength and good in stability.
Description
Technical field
The utility model relates to a kind of bridge gear shaft.
Background technique
The mechanical strength that carrier gear bears is larger, and bridge gear shaft easily produces wearing and tearing after using a period of time like this.
The model utility content
In order to address the above problem, the utility model provides a kind of bridge gear shaft.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of bridge gear shaft, comprise the body that cooperates with carrier gear, side at body is provided with the First terrace, opposite side at body is provided with the second step face, is provided with the 3rd step surface in the outside of First terrace, is provided with keyway on vertical surface of body, described keyway is communicated with the second step face, and described keyway is made as circle near a side of First terrace, and the diameter of described First terrace is greater than the diameter of body, and the diameter of described second step face is less than the diameter of body.
The diameter of described the 3rd step surface is identical with the diameter of second step face.
The width of described the 3rd step surface is half of second step face width degree.
The width of described First terrace is half of the 3rd step surface width.
Described First terrace, second step face, the 3rd step surface and the coaxial setting of body.
Bridge gear shaft through above-mentioned design, because concentricity is guaranteed, and can regulate by keyway the cooperation of carrier gear and bridge gear shaft, can reduce carrier gear in the process of rotation to the vibrations of bridge gear shaft, simple in structure, intensity is high, good stability.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the structural drawing of the described bridge gear shaft of the utility model embodiment.
Embodiment
As shown in Figure 1, the described bridge gear shaft of the utility model embodiment, comprise the body 1 that cooperates with carrier gear, side at body is provided with First terrace 2, opposite side at body is provided with second step face 3, be provided with the 3rd step surface 4 in the outside of First terrace 2, vertical surface at body is provided with keyway 5, described keyway 5 is communicated with second step face 3, and described keyway 5 is made as circle near a side of First terrace 2, the diameter of described First terrace 2 is greater than the diameter of body 1, and the diameter of described second step face 3 is less than the diameter of body 1.
The diameter of described the 3rd step surface 4 is identical with the diameter of second step face 3.
The width of described the 3rd step surface 4 is half of second step face 3 width.
The width of described First terrace 2 is half of the 3rd step surface 4 width.
Described First terrace 2, second step face 3, the 3rd step surface 4 and body 1 coaxial setting.
Bridge gear shaft through above-mentioned design, because concentricity is guaranteed, and can regulate by keyway the cooperation of carrier gear and bridge gear shaft, can reduce carrier gear in the process of rotation to the vibrations of bridge gear shaft, simple in structure, intensity is high, good stability.
