Measuring system for gear and special hand-held movable optical back reflector
2010
The utility model discloses a measuring system for a gear and a special hand-held movable optical back reflector. The global measuring equipment of the system adopts a multi-path laser interfere tracking system, wherein the multi-path laser interfere tracking system comprises at least three laser interfere tracking instruments, the hand-held movable optical back reflector and a fixed optical back reflector; the hand-held movable optical back reflector is matched with the at least three laser interfere tracking instruments to use and used for carrying out space positioning on the gear to be measured; the fixed optical back reflector is used for carrying out space positioning on front-end measuring equipment; the hand-held movable optical back reflector comprises a reflecting mirror and a positioning mechanism; and the positioning mechanism is connected with the reflecting mirror and used for enabling the hand-held movable optical back reflector to move on a datum plane of the gear to be measured along a specific direction. The measuring system and the measuring method can be used for accurately measuring super-large high-precision gears with the diameters of 3,000-10,000mm, the minimum modulus of 6mm and the precision of over 6 grades. In addition, the manufacturing level of the super-large high-precision gears is improved.
