Buffering type belleville spring with buffering protrusions

Abstract

The utility model discloses a buffer type belleville spring with buffer protrusions, which comprises a loop bar and a plurality of belleville spring components sleeved on the loop bar, each belleville spring component comprises a first belleville spring and a second belleville spring which are coaxially arranged, and the taper of the first belleville spring is smaller than that of the second belleville spring; a plurality of sliding grooves distributed in the radial direction of the second disc spring are formed in the outer edge of the second disc spring, and a screw penetrating through the sliding grooves is fixedly connected to the bottom of the outer edge of the first disc spring. According to the disc spring assembly, when mechanical equipment runs and generates vibration or impact load, the disc spring assembly starts to work, the taper of the first disc spring is small, the first disc spring deforms earlier than the second disc spring in the initial compression stage, the second disc spring also starts to deform along with increase of the load, smooth transition is achieved through different deformation rates of the first disc spring and the second disc spring, and therefore the mechanical equipment can be stably compressed. And meanwhile, the arc-shaped metal elastic sheet also participates in the energy absorption process, so that the overall buffering effect is further improved.
