Abstract
The utility model relates to a supercharger, in particular to a primary piston anti-loosening device of the supercharger. The upper face and the lower face of a primary piston body of the device are respectively provided with a mounting groove and a circular gasket. The circular gaskets are made of white steel, the circular gaskets are fixed in the mounting grooves of the primary piston body through inner hexagon screws, and through holes are formed in the centers of the circular gaskets. A piston rod penetrates through the primary piston body and the through holes of the circular gaskets to be connected with a lock nut. By means of the primary piston anti-loosening device of the supercharger, the phenomenon that the lock nut and the piston body are abraded so that looseness can be caused is avoided, the normal concentricity of a piston is guaranteed, safe and stable operation of the supercharger is guaranteed, and the defect that a lock nut and a piston body of a primary piston of an existing supercharger set can be abraded easily so that looseness can be caused is overcome.
Description
Technical field:
The utility model relates to a kind of pressure-increasing machine, particularly a kind of pressure-increasing machine first stage piston anti-loosening device.
Background technique:
Existing supercharging unit first stage piston body is aluminum, the lock nut of fixed piston rod center hole is irony, when piston is in cylinder when to-and-fro motion, because piston only material is soft, between running a period of time body and lock nut, just there will be gap, cause piston and cylinder sleeve decentraction, piston assembly, filler assembly damage, when serious, piston rod distortion fracture, piston are taken blame for others, deflection of crankshaft, linkage mechanism smash casing, can breaking out of fire explode because there being rock gas to produce spark in cylinder, have major safety risks.
Model utility content:
The technical problems to be solved in the utility model is to provide a kind of pressure-increasing machine first stage piston anti-loosening device, and this device has realized that to prevent that the wearing and tearing of lock nut and piston only from producing loosening, ensures the normal concentricity of piston, guarantees the operation of pressure-increasing machine safety and steady.Overcome the loosening deficiency of the lock nut of existing supercharging unit first stage piston and piston only generation easy to wear.
Technical solution adopted in the utility model is: a kind of pressure-increasing machine first stage piston anti-loosening device, comprises rounded washers; First stage piston body top and bottom are equipped with mounting groove and rounded washers are all installed, rounded washers adopts white steel, rounded washers is fixed on by socket head screw in the mounting groove of first stage piston body, rounded washers center has through hole, and piston rod is connected lock nut through the through hole of first stage piston body and rounded washers.
The beneficial effects of the utility model are: the utility model is owing to having adopted rounded washers, thereby have and prevent that lock nut and piston only wearing and tearing from producing loosening function, ensure the normal concentricity of piston, guarantee the operation of pressure-increasing machine safety and steady.
Brief description of the drawings:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is the structural representation of rounded washers.
Fig. 2 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of pressure-increasing machine first stage piston anti-loosening device, comprises rounded washers 1; First stage piston body 2 top and bottom are equipped with mounting groove and rounded washers 1 are all installed, rounded washers 1 adopts white steel, rounded washers 1 is fixed on by socket head screw 3 in the mounting groove of first stage piston body 2, rounded washers 1 center has through hole, and piston rod 4 is connected lock nut 5 through first stage piston body 2 with the through hole of rounded washers 1.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
