Abstract
The utility model relates to a bolt connecting structure which structurally comprises two transmission shafts and a fixed bolt, wherein one transmission shaft is provided with a fixed hole, and the other transmission shaft is also provided with a fixed hole at the corresponding position; the fixed bolt penetrates through the fixed holes of the two transmission shafts, and the other end of the fixed bolt is screwed into a nut; and the end of the fixed bolt, screwed into the nut, deforms by chambering. In the utility model, the fixed bolt is screwed into the nut and then subjected to chambering at the rear end so as to cause the fixed bolt to deform, thus being effectively controlled under vibration and impact conditions without loosening; and the technique is simple, and the connection is reliable.
Description
Technical field
The utility model relates to a kind of bolt fastening structure.
Background technique
Bolt fastening structure is simple, and mounting or dismounting are convenient, and various bolts connect standardization, though be widely used, but along with the development of mechanical transmissioning technology, big to transmission power, the connection between the transmission shaft that especially runs up, when starting with vibration with impact, after long-time the use, loosening phenomenon often appears in standardized bolt, influences transmission effect and working life, therefore, the connection between them is had higher requirement.
Summary of the invention
The utility model provide a kind of can be under with the vibration and the situation of impacting, the bolt fastening structure that can effectively connect.
The technical solution of the utility model is, structure comprises two transmission shafts 1,2, fixing bolt 3, have fixed hole on the described transmission shaft 1, also have fixed hole on the corresponding position on another transmission shaft 2, described fixing bolt 3 passes two transmission shafts, 1,2 fixed holes, and the other end is screwed into nut 4, and the end that described fixing bolt 3 is screwed into an end of nut is out of shape by reaming.
The utility model adopts after plain bolt connects transmission shaft, by after being screwed into nut on the fixing bolt, carrying out earlier reaming in the rear end, make its distortion, under the situation that can effectively be controlled at vibration and impact, the force direction that is subjected to that guarantees nut is the direction that is screwed into of nut, can not produce looseningly, technology is simple, connects reliable.
Description of drawings
Fig. 1 is a schematic representation of the present utility model.
Embodiment
As shown in Figure 1, structure comprises two transmission shafts 1,2, fixing bolt 3, have fixed hole on the described transmission shaft 1, also have fixed hole on the corresponding position on another transmission shaft 2, described fixing bolt 3 passes two transmission shafts, 1,2 fixed holes, and the other end is screwed into nut 4, and the end that described fixing bolt 3 is screwed into an end of nut is out of shape by reaming.
