Embodiment Construction
[0025] An embodiment of the present invention provides an abrasive belt grinding method for the surface of propeller shark skin, which is used to solve the problem of the abrasive belt grinding method for the surface of propeller shark skin. The technical solution is: provide an abrasive belt processing method for the surface of shark skin, first use the abrasive belt grinding head to grind out the smooth surface of the propeller, and then perform instantaneous micro-feed control when the grinding head and the propeller surface are relatively moving on the formed surface To grind out the required micro-element surface, and then carry out trajectory planning along the propeller surface to achieve the state of the shark skin-like surface. The abrasive belt grinding equipment for the propeller shark skin surface is composed of a contact wheel, a contact wheel bracket, an abrasive belt, a cylinder rod sleeve, and a cylinder. The method is conducive to the actual production and pro...

The invention discloses an abrasive belt grinding processing method of a sharkskin surface of a propeller, which is used for solving the problem of the abrasive belt grinding processing method of thesharkskin surface of the propeller. The technical scheme is that the abrasive belt processing method of the sharkskin surface is provided, the smooth surface of the propeller is ground by an abrasivebelt grinding head, a cylinder controls a contact wheel driven by the high-speed moving abrasive belt to provide instantaneous micro-pressure while performing feed movement on the propeller surface togrind the required infinitesimal surface, and infinitesimals arranged in a regular pattern are sequentially ground along the propeller surface to achieve the state of the sharkskin surface. An abrasive belt grinding processing method of a sharkskin surface of a propeller is composed of a contact wheel, a contact wheel support, an abrasive belt, a cylinder rod sleeve and a cylinder. Processing ofthe sharkskin-like structure on the propeller surface is achieved, and the method of processing the sharkskin surface of the propeller is created, thereby facilitating actual production and promotion.
Description
technical field [0001] The invention relates to an abrasive belt grinding method for the surface of propeller shark skin, belonging to the field of propeller processing. Background technique [0002] Due to the non-uniformity of the flow field during the operation of the propeller, it is often difficult to avoid unsteady cavitation on the surface of the propeller page, which will cause severe vibration of the ship, lead to cavitation erosion of the blade, and cause harmful consequences such as noise. According to statistics Cavitation noise accounts for 70%-80% of the operating noise of military propellers. At the same time, due to the high friction of the surface of the propeller in contact with seawater during high-speed operation, the resistance during the operation of the propeller is increased, which greatly reduces the operating speed of the propeller; and the surface shape of the propeller affects its performance. important factor in drag reduction characteristics. ...
