Abstract

The invention discloses a stepped shaft and a processing method thereof. The stepped shaft comprises a first shaft section, a second shaft section, a third shaft section, a fourth shaft section, a fifth shaft section, a first key groove, a second key groove, a first chamfer and a second chamfer. During processing, the processing method comprises the steps of material preparing, material forging, first thermal treatment, surfacing, rough turning, second thermal treatment, semi-finish turning, finish turning, surfacing, chamfering, rough milling of key grooves, semi-finishing turning of the keygrooves, third thermal treatment, rough grinding, finish grinding and polishing. According to the stepped shaft and the processing method, disclosed by the invention, two central holes are adopted aslocating references, the preparation is simple, the processing steps are clear, the processing efficiency is high, the effect is good, the processing is convenient and fast, the processing accuracy ishigh, the processing cost is saved, economic benefit is increased, batch production is convenient, good wear resistance and toughness are obtained, and the coaxiality, the accuracy, the roughness andthe like of the stepped shaft can meet the requirements.

Description

technical field [0001] The invention relates to the technical field of stepped shafts, in particular to a stepped shaft and a processing method thereof. Background technique [0002] Shafts are one of the main parts that make up a machine. All transmission parts (such as gears and worms) that perform rotary motion must be installed on the shaft to transmit motion and power. Therefore, the main function of the shaft is to support the rotating parts and transmit motion and power. According to the different loads of the shaft, the shaft can be divided into three types: the rotating shaft, the mandrel and the transmission shaft. The shaft that bears both the bending moment and the torque during work is called the rotating shaft, the shaft that only bears the bending moment is called the mandrel, and the shaft that only bears the torque but not the bending moment is called the transmission shaft. [0003] A stepped shaft is a mechanical part that supports a rotating part and t...
