The design of the bearing housings are based upon nature of lubrication process. The forced-feed lubrication system contains pressurised oil inside the housing, thus bearing housing is exposed to stresses and flow variance. The pressure-filled oil system contains consistent oil level, and the bearing housing is exposed to high temperature of the oil, whereas the pressure of the oil inside the housing remains normal. The manufacturing process of the material has been discussed, and the pre and post machining quality checks have bee elaborated.
The Computerised Numerical Control machines have offered smart way of machining the mechanical parts. The CNC machines ensure dimensional accuracy, and have prevented human and machining error. The different between machining process conducted by human and machine is that the human error i.e. the positioning of tool, and handling of tool during machining are extremely crucial, and therefore the human technicians are vulnerable to off-set certain dimensional measurements, which will eventually develop shortcomings inside the machined object. The CNC machines have controlled the dimensional accuracy and geometrical requirements.
Prior to the machining process, the solid block shall be tested and dimensionally verified. The part shall undergo non-destructive testing. ...Show more
