[0053] As a specific implementation of the self-propelled gun road wheel repair process provided by the present invention, the step of checking whether the wear-resistant steel ring is loose includes:
[0054] Apply ultrasonic waves to the load wheel, collect and compare the vibration amplitude of the wear-resistant steel ring and the hub of the load wheel, if the difference between the vibration amplitude of the wear-resistant steel ring and the hub is within the first rated range, the wear-resistant steel ring is not loose, If the difference between the vibration amplitude of the wear-resistant steel ring and the hub is within the second rated range, the wear-resistant steel ring is loose but can be repaired; if the difference between the vibration amplitude of the wear-resistant steel ring and the hub is within the first rated range and the second If the second rated range is outside, the wear-resistant steel ring is loose and needs to be discarded; the first rated range is ...

Abstract
The invention provides a self-propelled gun road wheel repair process and a self-propelled gun road wheel, which belong to the technical field of track wheels. The repair process of self-propelled gun road wheels includes the following steps: take the road wheels that meet the repair standards, check whether the wear-resistant steel ring is loose, if it is loose, reinforce it or discard it, if it is not loose, proceed to the next step; The working surface of the wear-resistant steel ring is surface treated; the plasma additive is cast on the working surface of the wear-resistant steel ring. The self-propelled gun road wheel includes a hub, a wear-resistant steel ring arranged on the hub, a fastener, a hard filling body and a plasma additive casting layer. The invention can realize the repair of the road wheel of the self-propelled gun later, and the repair is simple and convenient, the repair period is short, and the cost of repair is also low. After the repair, the road wheel can be directly recycled, which can save a lot of resources and greatly reduce maintenance costs.
Description
technical field [0001] The invention belongs to the technical field of track wheels, and more specifically relates to a repairing process of a road wheel of a self-propelled gun and the road wheel of a self-propelled gun. Background technique [0002] Self-propelled guns are usually driven by a track mechanism, and the road wheels are an important component of the track mechanism. In order to reduce the overall weight, the existing self-propelled gun road wheels usually use aluminum hubs 10, and on the working surface where the aluminum hubs are in contact with the tracks A wear-resistant steel ring 20 is provided to reduce the wear of the wheel hub. Due to the heavy working load of the road wheel and the high requirement for working stability, the aluminum wheel hub 10 is usually directly cast on the wear-resistant steel ring 20 during manufacture. The wear-resistant steel ring 20 and the aluminum wheel hub 10 are fitted with each other through the inner buckle slope 60, su...
