Anti-impact and wear-resistant transmission drive device of rewinding machine

Abstract

The invention discloses an anti-impact and wear-resistant transmission drive device of a rewinding machine. The anti-impact and wear-resistant transmission drive device is composed of a motor, a drive gear, a driven gear and a connection rod, wherein the drive gear is arranged on the output shaft of the motor in a sleeving manner, the driven gear is engaged with the drive gear, one end of the connection rod is hinged with the edge of the driven gear, a wear-resistant metal coating layer is sprayed on the surface of the drive gear, and the wear-resistant metal coating layer comprises the following components in percentage by mass: 0.20-0.25% of C, 11.3-14.4% of Al, 14.6-17.5% of Mg, 1.25-1.50% of Fe, 0.40-0.7% of Si, 0.01-0.10% of Cu, 1.5-1.7% of Mn, 1.4-2.0% of Zn, 0.10-0.25% of Zr, 1.10-3.12% of rare-earth elements, less than 0.015% of impurities and the balance Ti; and the rare-earth elements contain the following components in percentage by weight: 15-18% of Gd, 3-5% of Pr, 7-9% of Dy, 12.5-12.8% of Ac, 15-20% of Nd, 11-13% of Sm and the balance La.

Description

technical field [0001] The invention belongs to the technical field of textile equipment, in particular to a transmission and drive device for an impact-resistant and wear-resistant rewinding machine. Background technique [0002] The current textile industry is developing rapidly. Due to the periodic movement of the guide wire rod controlled by the eccentric wheel, the surface of the eccentric wheel is unevenly stressed and easy to wear, resulting in the "S" surface being not smooth, the periodic motion of the guide wire rod is unstable, and the silk thread is inverted. Unevenness causes the weft feeding of the loom to be easily broken, seriously affecting the efficiency and quality of the loom's weaving; at the same time, due to the unevenness of the rewinding pattern of the silk thread, it often takes a lot of manpower and time to even the bobbin, resulting in a decrease in production efficiency , the problem of increased production costs, the power transmission device of...

[0002] The current textile industry is developing rapidly. Due to the periodic movement of the guide wire rod controlled by the eccentric wheel, the surface of the eccentric wheel is unevenly stressed and easy to wear, resulting in the "S" surface being not smooth, the periodic motion of the guide wire rod is unstable, and the silk thread is inverted. Unevenness causes the weft feeding of the loom to be easily broken, seriously affecting the efficiency and quality of the loom's weaving; at the same time, due to the unevenness of the rewinding pattern of the silk thread, it often takes a lot of manpower and time to even the bobbin, resulting in a decrease in production efficiency , the problem of increased production costs, the power transmission device of the existing rewinding machine is cumbersome and time-consuming to operate, and the parts are easily damaged during the operation, which shortens the service life. A kind of rewinding machine transmission that can overcome the above defects is developed Mechanism and its simple method of operation have become a technical problem to be solved urgently by those skilled in the art
