At present, only about gear industry production plant with 300 gears basic equipment supporting the measuring chamber , a total of about 200 sets of coordinate measuring instrument , mostly imported from abroad ; types ( mechanical , optical , CNC ) Gear Measuring Instruments 1000 I units, of which 30 sets of gear measuring center , assembly testing equipment, inspection instrument worm pay about 10 sets , transmission and drive axle test bench test bench does not exceed 50 ; roundness , length measurement , optical dividing head , roughness tester , projector, universal tool measuring instruments and other types of more than 500 units. The rest, about 200 gear manufacturing plant is almost no precision measuring instruments, some enterprises in addition to universal measuring tool , but do not have a measuring instrument .
Experts pointed out that , in order to further improve product quality gear industry and competitiveness , as soon as possible with the appropriate types of precision test instruments. In the coming years , and medium-sized enterprises should be equipped with gear coordinate measuring machines, gear measuring centers and other precision measuring instruments and measuring chamber equipped with a complete center , small enterprises should also be equipped with necessary precision measuring instruments .

Gears concept: to be able intermeshing gear toothed mechanical parts, it is in the whole machinery of mechanical transmission and field of application is extremely broad.

The composition of the gear tooth structure generally , alveolar , face, France face addendum circle , tooth root circle , the base circle , pitch circle .

Gear : short teeth , the gear for engaging the projections of each part , the convex portion generally radially arranged on the gear tooth pair in contact with each other , can operate in constant engagement gear ; splines on the gear the space between two adjacent teeth ; face is a cylindrical or cylindrical worm gear , the worm gears or the axis perpendicular to the plane ; normal plane perpendicular to the mean plane of the tooth line ; addendum circle where the tooth tip is round ; tooth root circle is the circle where the bottom ; base circle is formed involute generating lines for pure rolling circle ; pitch circle of the gear is calculated within the face of the reference circle geometry .

Gear Category: their shape into cylindrical gears, bevel gears , non-circular gears, rack, worm ; according Tooth shapes into straight gears, helical gears , herringbone gears , curves gear ; located at the surface of the tooth into the external gear , internal gear .
