Precision gear manufacturing process

Abstract

The invention relates to a precision gear manufacturing process. A precision gear manufacturing device is used in the process. The precision gear manufacturing device comprises a supporting frame, a polishing mechanism and a cooling and clearing mechanism, the section of the supporting frame is of a rectangular structure, the polishing mechanism is installed in the middle of the lower end surfaceof the supporting frame, and the cooling and clearing mechanism is connected to the polishing mechanism. The cooling and clearing mechanism is installed on the supporting frame. The problems that an existing device cannot effectively polish complex notches of a gear groove, surface burrs of gear teeth cannot be removed effectively and the transmission precision of a gear is influenced can be solved. The problems that when the existing device polishes the gear, the gear cannot be cooled in time, as a result, due to too high temperature of the surface of the gear, the gear teeth are deformed, iron scrap residues generated by polishing cannot be cleared in time, as a result, the iron scrap residues adhere to the gear groove and the surfaces of the gear teeth again at high temperature, and thepolishing efficiency of the gear and precision of gear transmission are influenced can also be solved.

Description

technical field [0001] The invention relates to the technical field of gear processing, and specifically proposes a precision gear manufacturing process. Background technique [0002] A gear is a mechanical element with gears on the rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of generative gear cutting method and special machine tools and cutting tools using this principle appeared one after another. With the development of production, the stability of gear operation was paid more attention. Gears and their gear products are important basic parts of mechanical equipment, and the main transmission parts of most complete sets of mechanical equipment are gear transmissions. With the rapid development of the national economy, the total annual sales of the entire industry have exceeded 100 billion yuan, forming an industry pattern in which multiple enterp...

AI Technical Summary

Problems solved by technology

The development speed of gears is very fast, and it is also widely used in mechanical equipment. However, burrs generally appear on the surface of gears after casting, which directly affects the accuracy of gear transmission. Therefore, a precision gear manufacturing process is proposed. The gears are fully polished to increase the precision of gear transmission

[0003] In the process of precision gear machining, according to its casting characteristics, it is necessary to grind the tooth grooves and teeth of the gears: the existing precision gear manufacturing devices have the following defects: 1. The existing precision gear manufacturing devices cannot target the tooth grooves Effective grinding of complex notches cannot effectively remove the burrs on the surface of the gear teeth, which will cause the gears to freeze during use and affect the precision of gear transmission; 2. The existing precision gear manufacturing devices cannot be polished in time The cooling and cooling treatment of the gears will cause the teeth to be deformed if the surface temperature of the teeth is too high, and the iron filings residues generated by grinding cannot be cleaned in time, causing the iron filings residues to re-adhere to the tooth grooves and teeth at high temperatures The surface affects the grinding efficiency of the gear and the precision of the gear transmission
