Problems solved by technology

The invention patent of Chinese patent application No. CN201410286087.3 provides a double gear tooth-tooth assembly tool and its assembly method. The large and small gears are finely ground and assembled in the assembly tool. The phase angle after tooth alignment is The deviation can reach no more than 1′, but the phase angle deviation of the high-precision duplex gear usually requires to reach 30″, and some even require it to reach within 10″, so only the method of tooth-aligning tooling cannot guarantee this high-precision Duplex gear tooth phase angle deviation

Abstract

The invention provides a process for processing the high-accuracy phase difference of a duplicate gear. The process adopts a gear aligning tool. According to the process, a finely ground pinion and a coarsely ground gearwheel are assembled in an assembly tool to ensure the concentricity of the pinion and the gearwheel, and the phase angle deviation is controlled in a certain range; gear teeth of the gearwheel are finely ground on a gear grinding machine by taking the positioning reference of gear teeth of the pinion shaft as the gear grinding reference of the gearwheel, so that the relative accuracy of gear forms of the pinion and the gearwheel can be improved, the condition that the phase difference of a duplicate gear is less than 10seconds can be ensured, and the duplicate gear can achieve high-accuracy phase difference. The process is very applicable to transmission of a high-accuracy duplicate gear.

Description

technical field [0001] The invention relates to a high-precision phase-difference processing technology for dual gears, and is especially suitable for processing high-precision phase-difference dual gears. Background technique [0002] Duplex gears are widely used in various gear transmission systems. Some double gear design drawings require to ensure the phase angle deviation of the two gear teeth, such as the double planetary gear in the NW gear train of the mine truck wheel reducer, the large and small gear teeth of the double planetary gear The smaller the phase angle deviation, the more balanced the power distribution of the system, and the more uniform the load borne by the gear distribution. The invention patent of Chinese patent application No. CN201410286087.3 provides a double gear tooth-tooth assembly tool and its assembly method. The large and small gears are finely ground and assembled in the assembly tool. The phase angle after tooth alignment is The deviatio...
