The benefit of this XYZ engine bed is any engine can be hooked up on the test bed with less modification on the engine rubber mounting, engine flywheel adapter and oil adapter. Hakita’s designed an XYZ axis of Engine Bed with the main focus of having precise and easy alignment for the shaft coupling between the engine and the dynamometer. The Engine Bed has the advantages of a low installation cost and enabling rapid engine change, allowing maximum accessibility to the engine, and the ability to support engines with a wide range of physical sizes and power. The Engine Bed consists of base frame, sub-frame and height adjustable stand. The base frame and sub-frame is designed such a way to ease length and width adjustment by means of sliding support stands. The sliding groove machined on the base frame and sub-frame rail enables the sub-frame and height adjustable stand to move along the way to suit with the engine mounting position. The height adjustable stand is precise and easy to be installed by means of trapezoidal thread spindles of the support stands. T-slot nut is use to hold tighten between the adjustable stand and sub-frame and between the sub-frame and base frame. The Engine Bed is a static unit for direct floor fixing in the test cell using wall plug. Metal Arc Welding makes the main structure of S41C or S45C mild steel with all the parts jointed. Heavy-duty protective coatings paint, misty grey (1457), is sprayed thoroughly for the metal finishing for corrosion protection due to resistant painting and galvanized and oiled spindles and nuts.
