DESC:TECHNICAL FIELD
The present disclosure relates to mechanical engineering More particularly, the present disclosure relates to a composite bush for housing with sealing and fastening capability.
BACKGROUND
Housings and castings are critical components in various industries, including automotive, mechanical, and liquid holding/filling applications. These components are used to hold and support other parts, and as a result, they need to be securely fastened. Fasteners such as nuts, bolts, screws, and rivets are commonly used to attach parts to housings and castings. However, traditional methods of securing fasteners involve tapping threads into the housing or casting material. This process can damage the threads and lead to leakage, which can cause maintenance and replacement costs.
One of the most common problems associated with traditional thread tapping methods is thread damage. When threads are tapped into housings and castings, there is a risk of damaging the threads, which can lead to leaks and other issues. This is especially problematic when the housing or casting is used to hold liquids. If the threads are damaged, the liquid can leak out, causing further maintenance costs and potentially damaging other components.
Furthermore, housings and castings that are used to hold liquids must be periodically drained and refilled. This can cause additional damage to the threads, which can lead to further leakage and maintenance costs. This maintenance requirement can result in downtime, which can impact the productivity of the equipment or machinery.
Therefore, there is a need for technology that overcomes these drawbacks, is risk associated with threads, maintenance cost.
