Description
Technical Field
The invention relates to equipment and a process for milling an inner hole of a bearing bush.
Background
The bearing bush (bearing shell) is a part of a sliding bearing contacted with a shaft neck, is in a tile-shaped semi-cylindrical surface, is very smooth, is generally made of wear-resistant materials such as bronze, antifriction alloy and the like, and can be made of wood, engineering plastics or rubber under special conditions.
The bearing bush material is usually soft, the inner cylindrical surface is not suitable for being processed by a grinding method, and the bearing bush material can be processed by boring, diamond boring, scraping or grinding. The grinding should not be done by the method of matching the shaft diameter, but should be done by a special grinding rod with the same size as the hole size of the bearing bush. The scraping is mainly used for partial tile bearings and is carried out by a wide-edge scraper. When scraping by hand, the scratch should be shallow. The bearing bush with the complicated inner surface shape adopts a special boring method according to the specific shape.
