Electric cylinders are also commonly referred to as electric slides, electric actuators, servo linear modules, single axis robots, and the like.
The conventional ball screw type electric sliding table is generally designed and manufactured by taking a linear guide transmission part and a servo motor part driven by a ball screw as two independent parts. The linear guide part and the servo motor are connected through a coupler, a synchronous belt switching mode and the like. When the shaft coupling is adopted for connection, the defect is that the concentricity of the shaft end of the ball screw and the shaft end of the servo motor cannot be ensured during installation, so that the ball screw and the servo motor are difficult to be directly butted by using a rigid shaft coupling, and the connection is usually carried out by adopting a flexible shaft coupling with a concentricity adjusting function. However, the flexible coupling can reduce the response speed of the servo motor, reduce the transmission precision and increase the length size of the transmission mechanism. The acceleration of the ball screw transmission structure is generally limited to 0.7G (1G ≈ 9.8 m/sec) due to the limited response speed of the servo motor2) The following. When the synchronous belt is used for connection, although the length dimension can be reduced, the synchronous belt has the defects of lower transmission precision and response speed than a coupler, and the width installation dimension of the electric cylinder is increased due to the side installation of the motor.
