Idlers/Rollers
Published in D.V. Subba Rao, The Belt Conveyor, 2020
Circlips are a type of retaining rings or fasteners that take the form of a flexible, open-ended ring, made from metal and used for holding structural components on the shaft. Fundamentally, there are only two types: internal, which are typically used to hold a seal or bearing in its bore by fitting inside a cylindrical bore or housing and push outwards, and external, which are used to locate components on shafts by fitting around a shaft and pressing on it. These are not load-carrying members. These are selected based upon experience to suit the duty conditions. Such retaining or fastening components are, cost-wise, negligible, but performance-wise, these are critical parts. Poor-quality and inadequately designed circlips may result in unexpected failure of the rollers.
Numerical and Experimental Studies of a Wet Multidisc Clutch on Temperature and Stress Fields Excited by the Concentrated Load

As shown in Figure 2, the multidisc clutch consists of the cylinder liner, piston, separate plates, friction discs, back plate, outer circlip, etc. In it, separate plates and friction discs are alternately arranged. The friction discs splined to the input shaft are driving components, and the cylinder liner, separate plates, and output shaft, mounted in series, are driven components. During the clutch engagement process, the applied pressure from the oil feeding system pushes these components into axial moving, and the out circlip stuck in the groove of cylinder liner restricts the axial displacement (Yang and Lam (18); Li, et al. (19)). Then, the gap between the discs and the plates is eliminated gradually. In addition, the speed difference between the driving and driven components declines to zero.
Tapboost - the design for manufacture of a low voltage water pump to boost the poor domestic water flow rate
Published in Australian Journal of Mechanical Engineering, 2023
The speed of the motor was dictated by the speed metre in which the flow turbine would rotate. This controlled the boosted flow respective of the original water flow rate seen at the point of installation. A circlip was then located on top of the turbine cage snapping into a groove machined in the outlet port of the brass pump housing. This acted as a protective barrier between the flow turbine and non-return valve. The purpose of the non-return valve was to prevent a backflow of water once the outlet valve is closed. This backflow of water, known as water hammer, can damage the flow turbine affecting the performance of the product for future use.
