Abstract Belt machine is a kind of machine for machining of the workpiece surface, mainly used for grinding metal, ceramic, glass etc。。 It is the use of abrasive particles on the metal workpiece grinding belt on the roughness of its surface changes。 Its adaptability is strong, can improve the size precision of the workpiece, reduce the surface roughness of the workpiece, in the metal grinding industry wide application。
This design content for desktop abrasive belt grinding machine design, including the structure of the abrasive belt grinding machine layout design, device design and transmission system design。The transmission system design of the three transmission, can let belt by 3 and 4, the speed of 5m / s rotation to grinding of different kinds of workpiece。 Through checking the active roller shaft and bearing strength, to ensure the driving roll the required strength, through the fatigue strength of the check belt to ensure belt does not slip, with certain strength and fatigue life。 In addition, the layout design of the motor, the working device, the transmission device and the supporting device is designed to ensure the rationality of the low center of gravity and the structure。 Have certain guidance and reference significance of design and development of the design of the plane belt grinding machine。
Keywords:Desktop belt machine; Variable speed drive; Roller shaft strength;Bearing strength
