The design of servo drive system has become the key technology of the automation industry. The newly developed servo system not only includes motor drive ", motion control System, first, and servo system design techniques, emphasizing the digital servo (3) based on digital signal processing chip (DSP) and using the DC motor servo drive system as the servo system «the method and the continuous technology are improved. Direction. Therefore, servo motors can be widely used in assembly machines, inspection devices, semiconductors, and TFT-LCD manufacturing devices. Servo system refers to the realization of a mechanical, system, position, speed, or acceleration control via closed loop control. system. A servo system consists of two parts: a plant, an actuator (actuat〇r), and a controller (contr〇Uer). The controlled system refers to the controlled object, such as a mechanical machine. Arm, or a mechanical working platform. The function of the actuator is to mainly provide the movement of the controlled body: it may be presented in the form of air pressure, oil pressure or electric drive. If it is oil-gastric or 4-way, it is generally called hydraulic servo system. At present, most servo systems are powered by electric motors. The actuators include motors and power amplifiers. In particular, the motor used in the servo system is called a servo motor (saw ηΜπ), usually 5 M324344 contains position feedback. Devices, such as optical encoders or resolvers (reso 1 ver), are currently mainly used in industrial servo motors including DC servo motors, permanent magnet AC servo motors, and inductive AC servo motors, among which Permanent magnet parental servo motors account for the vast majority. The function of the controller is to provide closed-loop control of the entire servo system, such as torque control, speed control, and position control. However, with the development of poor communication, communication, and automation technology, various automatic control devices have gradually increased the application range, thus providing smoother operation and a smoother torque curve, which is called for the servo motor. necessary. [New content] The purpose of this creation is to provide a servo motor back system elimination mechanism in which the output shaft of the feeding motor can withstand the axial thrust sub-limit output shaft for axial movement. The second purpose of this creation is to provide a servo motor back system elimination mechanism in which the output shaft of the servo motor is more uniform and the output accuracy is more stable. The servo motor backing elimination mechanism capable of achieving the above-mentioned novel purpose comprises: a motor 'system' extending from the two end faces of the first output shaft and the second output sleeve, wherein the output shaft is pivotally connected to the screw shaft, and (4): The output shaft is externally set up with worm teeth; the moon brother pushes the bearing, and the center is provided with a center hole, and the center is threaded through the sleeve 3 ★ after the first - thrust bearing - the end surface is in contact with the motor; The second thrust bearing is provided with a TU hole, and the center is threaded through the sleeve. After the shaft is pulled out, the second thrust bearing is in contact with the motor on the other side of the mountain; a 7L piece is adjusted through the inner screw to Ding 4 s system mouth and brother 2 output shaft screw 6 M324344 The second thrust bearing and the motor lock each other. [Embodiment] 4 tea reading Figure 1, the servo motor back system elimination mechanism provided by the present invention mainly includes: a motor (1), a first thrust bearing (2), a second thrust bearing (3) ) and an adjustment component (4). ° Hai motor (1) is a stepping motor (stepping mo tor), servo motor (servo r) straight brushless motor, or induction motor (丨n (juc丨ng m〇t〇r), the sense should The motor controls the rotation speed and positioning of the motor (i) by an inverter, and the motor (1) extends from the two end faces to the first output shaft (n) and the second output shaft (12). The first output shaft (11) is pivotally connected to one end of the screw (13), and the outer diameter of the second output shaft (12) is provided with a screw (122); the β-th thrust bearing (2) a central hole (21) is provided, the center of which is sleeved on the first output shaft (1) of the motor (1), and one end surface of the first thrust bearing (2) is in contact with the motor (1); The push bearing (3) is placed on the second output shaft (1 2 ), and (1) is in contact with each other; a central hole (31) is disposed, and the center thereof is passed through one end surface of the second thrust bearing (3). And the adjusting element (4) is mounted on the second output shaft (10) of the motor (1), and is screwed to the threaded shank 22 of the second output shaft (12) via the internal thread U22), and can be phase-phased Second stop Bearing ⑺ ⑴ produce an axial displacement of the motor in order to = the first thrust bearing (3) and the motor (1) secured to each other locks. Today's automatic feed m feed or micro-compensation feed device uses the feeding machine 7 M324344 motor, while the word service motor is set on the platform, up, in the micro-feed device, the servo: port...M provides a fixed servo horse The pivot is set on the bearing seat, and the screw is cupped. The two ends of the screw are respectively worn on the upper part, and the sub-hunting is pivoted on the platform by the bearing seat, and then driven by the power source of the feeding motor, the servo motor# One end provides power, and the other end of the screw is connected to a coded power source. When the servo motor screw is turned, the output shaft of the motor will rotate and drive the screw to rotate while That is, by using a device to sense the number of turns of the screw, the encoder, the pitch _, to feed back the message to the control center. Turn: the power source of the square motor is often single-(four), and (4) 1 i' and reverse Multiple steering, plus the screw connected to the output shaft, the eight-matched nut, and the rolling element arranged between the return passage of the screw nut (4) often have a small small „' these tiny gaps in the micro-into Feeding; the great dimensional tolerance of the middle is added When the inner rotor and the servomotor 0C80 element there is often a gap hanging gap months' cause the rotor coaxially with the output shaft of the forward rotation and reverse rotation is applied to the frequency output frequent case, the motor generates the servo gap is frequent.
