Light aluminum alloy wheel box

Abstract

The invention discloses a light aluminum alloy wheel box. Two slide block square holes are formed in the left side and the right side of the upper end of the contact surface of a box shell and a box lid respectively, two square slide blocks are placed in each slide block square hole, and each square slide block is provided with a longitudinal threaded hole. The light aluminum wheel box has the advantages that the slide block square holes are added, and stress of the whole structure is not influenced. The slide block square holes reduce the material and the self-weight and save the cost; each elliptical through hole can cover a mounting hole corresponding to H steel above the wheel box, the situation that the holes are misplaced cannot be generated, and therefore, mounting bolts at the topcan be successfully installed; by the adoption of the cooperation of the square slide blocks and the square holes, when the bolts are installed, the situation that the bolts follow the rotation is effectively avoided; the bolts directly wear the slide blocks instead of a box body so that the slide blocks can be renewed simply when abrasion is severe, the material is saved, and the replacement timeis also saved.

Description

technical field [0001] The invention belongs to the technical field of transmission mechanisms, in particular to a light-duty aluminum alloy wheel box. Background technique [0002] The existing walking box is made of cast iron and connected at the top. The top of the box is drilled and tapped to form threaded holes. When the top of the box needs to be connected with other components (such as H-beam), the screws pass through the top thread The holes are connected to the parts to be connected. This connection method has many disadvantages: 1. The connection holes of the parts to be connected sometimes do not correspond to the threaded holes on the top of the box, but because the positions of the holes are fixed, the holes between the holes The position cannot be adjusted; 2. After long-term use, the threaded holes are easy to wear, and the entire walking box should be scrapped and replaced. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, t...

Problems solved by technology

[0002] The existing walking box is made of cast iron and connected at the top. The top of the box is drilled and tapped into a threaded hole. When the top of the box needs to be connected with other components (such as H-shaped steel), the screw passes through the top thread There are many disadvantages in this connection method: 1. The connection holes of the parts to be connected sometimes do not correspond to the threaded holes on the top of the box, but since the positions of the holes are fixed, the distance between the holes The position cannot be adjusted; 2. After long-term use, the threaded holes are easy to wear, and the entire walking box needs to be scrapped and replaced
