29557244 Gear Allison spare parts

Allison 29557244 gear, as a core component of the original gear transmission from Allison, focuses on solving the core needs of power transmission, speed regulation, and precise meshing in transmissions. It is widely used in the transmission systems of Allison’s full range of heavy-duty automatic transmissions and various heavy commercial vehicles, engineering and mining machinery. The products strictly adhere to the original manufacturer’s production standards, with full-process quality control from the selection of 20CrMnTi alloy steel ingots, precision forging, normalizing and tempering treatment, five-axis precision milling, carburizing and quenching strengthening, tooth surface precision grinding, and phosphating rust prevention treatment, to dimensional inspection, gear meshing accuracy testing, wear resistance testing, and dynamic balancing inspection. This eliminates problems such as poor meshing, transmission jerking, tooth surface wear, and tooth root fracture caused by forging defects, insufficient machining accuracy, improper heat treatment, and tooth profile deviations. The products are suitable for complex working conditions such as heavy loads, high-frequency meshing, high-speed operation, severe vibration, and high temperature, and comply with the processing and quality standards of GB/T 3077-2015, GB/T 10095.1-2008, ISO 9001, and CE.
