Abstract

The invention discloses a rim bolt, comprising a bolt body, wherein the bolt body is formed in a way that a bolt head, a first step, a first screw rod, a second step and a second screw rod are sequentially connected; the first screw rod is provided with a spherical elastic washer; the spherical elastic washer is located below the first step; and the spherical elastic washer is a spherical rubber washer; in the use process of the rim bolt provided by the invention, the spherical elastic washer can be automatically centered when in contact with a spherical concave surface of the rim so as to guarantee the fully contact with the spherical concave surface of the rim and remove the processing or assembling error; the rim bolt has good anti-loosening performance, guarantees the connection reliability, and improves the use performance of a wheel type loader.

Description

technical field [0001] The invention relates to a rim bolt, in particular to a rim bolt used in a wheel loader, and belongs to the technical field of devices for fastening or fixing components or mechanical parts. Background technique [0002] Existing rim bolts, if attached figure 1 As shown, the bolt body is included, and the bolt body is formed by sequentially connecting a bolt head 1 , a spherical boss 2 , a first screw 3 , a second step 4 and a second screw 5 . In wheel loaders, if attached figure 2 As shown, the spherical boss 2 of the rim bolt is placed in the spherical concave surface 7 of the rim 6, the first screw rod 3 passes through the rim 6, the second step 4 of the rim bolt is stuck in the end surface annular groove 9 of the planetary wheel carrier 8, the second Two screw rods 5 pass through the planetary wheel carrier 8 and the wheel hub 10, and finally load onto the washer 11, and screw on the nut 12 to realize the connection. However, during use, it was...
