Specification for design and manufacture of pinion shafts

The pinion shaft is the key component in the transmission system of the mill, especially the large-scale self-grinding machine, semi-self-grinding machine and ball mill. It has strict requirements for material and manufacturing, complex process flow and high precision. Therefore, the selection, technology and manufacture of pinion shaft reflect a certain industrial level. For this reason, our pinion shaft process design and manufacturing standards have standardized and strict standards.
Operating under maximum allowable static and dynamic installation errors. Large and small gear sets should be able to transmit the design power (including the desired torque pattern and speed). The pinion shaft is forged with alloy steel as a whole. The gear is designed as a single helical tooth. It can be suitable in any direction of rotation (bidirectional), symmetrical in structure and can be used with adjustable head. When it is required to match the slow drive coupling, the pinion shaft should have a half coupling at both ends. If the surface of pinion is hardened, carburizing should be used instead of induction hardening. Gears must be hardened by gas carburizing according to AGMA, ASTM and ISO standards. Carburizing process must control heating and cooling process.
The tolerances of individual components of pinion are classified according to the corresponding accuracy level, including pitch error, tooth direction error, tooth profile error, tooth thickness and surface roughness. To measure gear runout (radial runout, end runout). After all hardening and tempering are completed, the residual compressive stress can be reduced by grinding the tooth surface after grinding, forming and heat treatment. Incorrect grinding at the tooth surface and root angle can cause tension stress or cracks in these areas. The accuracy of carburized gears should be up to AGMA2101-D04, AGMA6114 and AGMA2015 (A5), quenched and tempered gears should be up to AGMA2101-D04, AGMA6114 and AGMA2015 (A7). Metal inclusions (purity) shall be inspected in accordance with ASTM E45 and meet the requirements of AGMA 6114 Standard.
