Gear burr removing technology

Abstract

The invention relates to a gear burr removing technology. The technology comprises the following specific steps that 1, a burr removing device is constructed; 2, a gear is placed; 3, conducting and discharging are carried out; 4, an electrolyte is sprayed; 5, the gear is washed ultrasonically; 6, antirust treatment is carried out; and 7, the gear is naturally dried in air and delivered from storage. The technology has the following advantages that an anode terminal and a cathode terminal are utilized for conducting and discharging, the electrolyte is sprayed to the gear fast from bottom to top, the spraying speed is high, the electrolyte is sprayed in a centralized manner, and the burr removing effect is achieved; meanwhile, the burr removing effect is remarkable, the risk that the gear isbroken down is avoided, time for burr removing is short, and efficiency is high; the concentration of sodium nitrate is low, harm to the human body is avoided, corrosion to the surface of the gear isavoided, and meanwhile, the good burr removing effect can be ensured; and as the electrolyte spraying speed is high and the flow amount is large, the complex washing step in the later period is omitted, the gear only needs to be washed with clear water, the gear is washed ultrasonically, and thus greasy dirt on the surface of the gear can be decomposed and emulsified.

Description

Technical field: [0001] The invention relates to the field of gears, in particular to a gear deburring process. Background technique: [0002] Gears refer to the mechanical elements with gears on the wheel rim that continuously mesh to transmit motion and power.

[0003] Patent No. 201010208784.9 An electrochemical deburring equipment and its deburring process proposes the use of electrochemical methods to achieve the effect of deburring. Under the action of the electrolyte and the electrolyte, the two poles exchange charges, and the deburring of the casting is achieved through discharge, but the current is large, and the outflow of the electrolyte is small, there is a risk of the casting being broken down, and the gear structure is small. If there is no The limit is easy to shift, which affects the deburring effect. Due to the less electrolyte outflow, the deburring effect is poor. It takes tens of seconds to deal with a burr, and requires a high concentration of electrolyte, which is highly irritating and harmful to castings. The surface is highly corrosive and harmful to the human body. At the same time, due to the small amount of electrolyte outflow, the burrs are still attached to the gear surface. The gear surface needs to be cleaned with water and cleaning solution. The cleaning process is cumbersome, so this deburring process is not applicable. Due to the gear structure, and the deburring effect is poor, it takes a long time
