DD (direct drive) motor driving mechanism

Abstract

The invention discloses a DD (direct-drive) motor driving mechanism. The mechanism comprises a driving shaft, a DD (direct-drive) motor fixing seat, a DD (direct-drive) motor and a rotary encoder; theDD (direct-drive) motor fixing seat is installed at the left end of the driving shaft through a left bearing seat; the DD (direct-drive) motor is installed on the DD (direct-drive) motor fixing seat;the rotary encoder is installed at the right end of the driving shaft through a right bearing seat; the left bearing seat is clamped at the left end of the driving shaft through a bearing inner limiting cover plate and a bearing outer limiting cover plate; an angular contact bearing is installed between the bearing inner limiting cover plate and the left bearing seat; and framework oil seals areinstalled between the left bearing seat and the DD (direct-drive) motor fixing seat and between the bearing inner limiting cover plate and the left end of the driving shaft respectively. According tothe DD (direct-drive) motor driving mechanism of the invention, the number of accessories between the motor and the driving shaft is reduced; a printing stepping amount can be obtained; and the printing stepping precision of a digital printing printer is improved.

Description

technical field [0001] The invention relates to the field of motor drive shafts, in particular to a DD direct drive motor drive mechanism. Background technique [0002] Digital printing is printing using digital technology. Digital printing technology is a high-tech product that integrates machinery, computer, electronic information technology and gradually formed with the continuous development of computer technology. [0003] The emergence and continuous improvement of this technology has brought a new concept to the textile printing and dyeing industry, and its advanced production principles and methods have brought an unprecedented development opportunity for textile printing and dyeing. [0004] The drive motor is indispensable in digital printing equipment. The operation of the drive motor directly affects the quality of printed products. In order to improve the quality of printing, improve the drive motor, such as figure 1 As shown, a reducer and coupling are adde...

AI Technical Summary

Problems solved by technology

However, in order to cooperate with the drive shaft of the digital printing motor, the number of processing parts is large, and the cumulative error of the installation of the components from the servo motor to the drive shaft is too large, resulting in a greatly increased defective rate of printed products, and there is no feedback information for the printing step amount , cannot be invented and adjusted in time
