Description
Technical Field
The utility model relates to a technical field of engine specifically is a belt pulley mounting structure.
Background
Because the belt pulley at the front end of the crankshaft of the engine needs to transmit large torque, the conventional mode of fixing the belt pulley by a single bolt cannot meet the transmission requirement of the conventional torque.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a belt pulley mounting structure can enough transmit big moment of torsion, and factor of safety is also high.
In order to achieve the above object, the utility model provides a following technical scheme: a belt pulley mounting structure, mounting structure with the belt pulley installation engine crankshaft front end journal on, mounting structure include connection pad, lower connection pad and clamp plate, last connection pad with lower connection pad the structure the same, all include the cross section for half a section of thick bamboo of semi-annular installation, be located the fender of half a section of thick bamboo left side of installation and right side and be located the mounting panel of half a section of thick bamboo lateral surface front end of installation, two half a section of thick bamboo of installation use the diameter of bent axle as the setting of central line symmetry on the side of bent axle to utilize the screw to link firmly the fender of two half a section of thick bamboos of installation homonymies, thereby will install that half a section of thick bamboos is fixed and install on the bent axle, the hole of belt pulley be provided with bellied mount table, the mount table links firmly through the bolt with the mounting panel, the clamp plate concentric with the bent, and the pressing plate is abutted against the outer side surface of the mounting table.
Based on above-mentioned technical scheme, the belt pulley is installed on the mounting panel of last connection pad and lower connection pad, go up connection pad and lower connection pad centre gripping on the bent axle, it is fixed to utilize the frictional force between last connection pad and lower connection pad and the bent axle, the screw is installed the clamp plate on the terminal surface of bent axle to utilize the positive pressure between the screw thread of screw can increase the frictional force between clamp plate and the belt pulley, use frictional force to fix the belt pulley on the bent axle, and then can transmit big moment of torsion, when the moment of torsion was too big to overcome frictional force, the belt pulley skidded, protected the belt pulley. The utility model discloses simple structure, spare part makes simply and with low costs, and the level to manufacturing process requires lowly, and assembly process level requires lowly, can satisfy the big moment of torsion transmission demand of belt pulley.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to the drawings, the present invention provides an embodiment: the utility model provides a belt pulley mounting structure, mounting structure with belt pulley 4 installation engine 2 front end journal on, mounting structure include connection pad 1, lower connection pad 3 and clamp plate 5, last connection pad 1 the same with lower connection pad 3 structure, all include that the cross section is half a section of thick bamboo 6 of semi-annular installation, be located fender 7 on half a section of thick bamboo 6 left side of installation and right side and be located the mounting panel 8 of half a section of thick bamboo 6 outside front end of installation, two half a section of thick bamboo 6 of installation use the diameter of bent axle 2 as the setting of central line symmetry on the side of bent axle 2 to utilize the screw to link firmly fender 7 of two half a section of thick bamboos 6 homonymies of installation, thereby will install half a section of thick bamboos 6 fixedly on bent axle 2, the hole of belt pulley 4 be provided with bellied mount table 9, mount table 9 links firmly through the bolt with mounting panel 8, clamp plate 5 with bent axle 2, the pressure plate 5 is fixedly mounted on the end face of the crankshaft 2 with screws, and the pressure plate 5 abuts against the outer side face of the mount table 9.
