Abstract
The utility model discloses an injection pump gear with rubber stress strips. The injection pump gear with rubber stress strips comprises a disk. A weight reduction cavity is reserved on the rear surface of the disk. The disk is provided with a plurality of weight reduction holes. The disk is further provided with a plurality of L-section grooves outside the weight reduction holes. Rubber stress strips are arranged in the grooves respectively, and the ends of the rubber stress strips, extending out of the disk, are tightly attached to the disk and bent towards the center of the disk radially along the disk. The injection pump gear is simple in structure and easy to implement, the service life of the injection pump gear is effectively prolonged, and operational stability of the injection pump gear is improved.
Description
Technical field
The utility model relates to field of gears, is specially a kind of fuel injection pump gear with rubber stress bar.
Background technique
Injection Pump is an important component part of diesel engine of vehicle, is used for spraying diesel oil to automobile cylinder.Gear is installed on the action component in the Injection Pump transmits component as motion, radial stress is larger during the running of prior art fuel injection pump gear, easily causes the gear radial structure damaged, reduces service life of gear.
The model utility content
The utility model purpose provides a kind of fuel injection pump gear with rubber stress bar, to solve the large problem of prior art fuel injection pump gear radial stress.
In order to achieve the above object, the technological scheme that adopts of the utility model is:
Fuel injection pump gear with rubber stress bar, comprise the wheel disc with central through bore, wheel disc dish edge forms a plurality of gear teeth, it is characterized in that: described wheel disc hub disk has lightening grooves in wheel disc, have a plurality of lightening holes around central through bore on the wheel disc, also being provided with a plurality of cross sections on the wheel disc in the lightening hole outside is L shaped fluting, be respectively arranged with the rubber stress bar with the form fit of slotting in the fluting, rubber stress bar is close to wheel disc and along the wheel disc radial to the wheel disc center curvature from the termination that wheel disc stretches out.
Described fuel injection pump gear with rubber stress bar is characterized in that: around a plurality of L shaped flutings are distributed in the wheel disc central through bore along even circumferential.
The utility model is simple in structure, is easy to realize, the radial stress when offsetting the gear rotation by the rubber stress bar that arranges in the fluting has effectively prolonged the working life of fuel injection pump gear, and improved the fuel injection pump gear working stability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1.Fuel injection pump gear with rubber stress bar, comprise the wheel disc 1 with central through bore 2, wheel disc 1 dish edge forms a plurality of gear teeth 3, wheel disc 1 hub disk has lightening grooves 4 in wheel disc, have a plurality of lightening holes 5 around central through bore 2 on the wheel disc 1, also being provided with a plurality of cross sections on the wheel disc 1 in lightening hole 5 outsides is L shaped fluting, a plurality of L shaped flutings are distributed in around wheel disc 1 central through bore along even circumferential, be respectively arranged with the rubber stress bar 6 with the form fit of slotting in the fluting, rubber stress bar 6 be close to wheel disc 1 from the termination that wheel disc 1 stretches out and along wheel disc 1 radially to wheel disc 1 center curvature.
