Gear pump assembly drawings how to draw is correct? Gear pump assembly diagram is the most intuitive expression of technical thinking, gear pump for the production of a great guide. Following Xiaobian detail gear pump assembly diagram of the specific drawing steps. When plotting the gear pump, you have to draw gear pump assembly drawings, because the only way to accurately express the assembly relationship. Before drawing gear pump assembly drawings, we must first understand the contents of assembly drawings. Mainly understand the general purpose of its assembly and the proportion of the figure. Gear pump assembly drawing method the following steps: â‘ According to the classification of parts drawings, draw the first figure. â‘¡ size analysis, draw all size lines, size boundaries, and then the actual measurement of size, the resulting data one by one fill in the size line. â‘¢ determine the technical requirements of the parts (surface roughness, limit and cooperation, the form of tolerances, heat treatment, etc.). â‘£ For parts on the structure of the process, such as chamfering, rounding, keyway, back groove and other structures should be read after the standard drawn in the gear pump assembly drawing, the main view using AA cutaway, showing the gear pump assembly relationship. The left view is taken along the left pump cover and the pump body, and is partially cutaway, showing the engagement of a pair of gears and the oil inlet and outlet. As the pump in this direction, the shape of the symmetry of the outer structure, so the view uses half a disassembled cross-sectional view and half the view of the expression. The top view is the top view of the gear oil pump shape view, because of its symmetry before and after, so that the rational use of the drawings and the layout of the entire picture is reasonable, so only painted a little more than half of the graphics.
