Light aluminum alloy wheel box

Technical Field

The invention belongs to the technical field of conveying mechanisms, and particularly relates to a light aluminum alloy wheel box.

Background

The existing walking box adopts cast iron material and the mode of connecting at the top, and box top drilling and tapping become the screw hole, when box top needs to be connected with other parts (like H shaped steel), the screw is connected with the part that needs to be connected through top screw hole, and such connected mode has a lot of defects: 1. the connecting holes of the parts to be connected sometimes do not correspond to the threaded holes at the top of the box body, but the positions of the holes are fixed, so that the positions between the holes cannot be adjusted; 2. after long-time use, the threaded holes are easy to wear, and the whole walking box body needs to be scrapped and replaced.

Further, a through hole is formed in the center of the hub, and a hexagonal spline is inlaid in the through hole.

The hexagonal spline is used for being embedded in the rotating shaft of the engine, and the spline is worn during the starting and decelerating processes of the engine. The existing spline is directly formed in the center of the hub, and once the whole wheel is worn, the whole wheel needs to be replaced, so that materials are wasted, the cost is increased, and the hub is inconvenient. The product designs the spline into a replaceable hexagonal spline, and once the spline is worn and can not be used any more, the spline is replaced singly.

Further, the hub is made of high-strength nylon, the box body and the hexagonal spline are both formed by aluminum alloy die casting, and the wheel is made of ball-milling cast iron.
