Coal Shearer boring machine gear [] product characteristics, you know how much?
Gear (Coal Shearer boring machine gear), teeth meshing continuously transmit motion and dynamic mechanical components, it is capable of intermeshing toothed rim on the mechanical parts. Large diameter gear is double the diameter of the pinion. Gear (Coal Shearer boring machine gear) used in the transmission appeared very early. 19th century, developed into Cutting Method Using this principle and the principle of special machine tools and gear cutting tools have emerged, along with the development of production, smooth gear (Coal Shearer boring machine gear) running attention. Coal Shearer boring machine is a dedicated special gear mechanical gear.
Coal Shearer boring machine gear precision gear refers to the shape of the integrated error divided one level, including the tooth, the tooth, diameter jumping and other important parameters, which refers to the radial shape of the tooth is teeth, tooth refers to the longitudinal shape of teeth, diameter hop refers to the distance between the teeth of two adjacent error, we generally automotive gear hobbing processing is completed by 6 to 7 can be used, and some of the press due to the need for high-speed operation and batch printing, high-precision gear they need to reduce the accumulated gear error leaving the printing effects caused by the decline, while domestic production grinding to level 4-5 processability, imported high-precision grinding machinability to 3, grade 3-4, and some can be processed to level 2.
