Feedback type lagging preventing movement worm shaft system

Abstract

The invention discloses a feedback type lagging preventing movement worm shaft system. The feedback type lagging preventing movement worm shaft system comprises a servo drive motor, a support, a speed reducer, a worm, a worm wheel, a coupler and a worm installing base. An output shaft of the servo drive motor is fixedly connected with the speed reducer. An output shaft of the speed reducer is connected with one end of the worm through the coupler. The worm is installed in the worm installing base. The worm wheel is in meshing transmission with the worm. A transition shaft sleeve is arranged at the other end of the worm. The transition shaft sleeve is fixedly connected with a transition coupler. An installing disc is installed at the end of the worm installing base. The installing disc is provided with a monitoring element and a monitoring element protection cover used for protecting the monitoring element. An output shaft of the monitoring element is connected with the transition shaft sleeve through the transition coupler. According to the design, the rotation situation of the worm can be fed back in time, the feedback type lagging preventing movement worm shaft system is compared with a servo drive element, whether the worm shaft system is in a lagging state and even in a rotation stopping state or not is judged, and the early finding rate of the fault is greatly increased. The service life of the worm wheel and the worm is prolonged, and the precision of machined components is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of numerically controlled machine tools, in particular to a feedback type anti-lag movement worm shaft system. Background technique [0002] With the advancement of science and technology, the demand for large, heavy, and high-precision parts continues to increase, such as wind power gears, marine propellers, etc., which greatly promotes the development of large and heavy CNC rotary tables. As an important part of the CNC rotary table, the worm shaft system is also developing in the direction of high precision, heavy load and high dynamic response. The pros and cons of dynamic response capabilities correspond to the degree of synchronization between the rotation of the worm and the rotation of the output shaft of the servo motor. The higher the synchronization, the better the dynamic response ability. The theoretical rotation angle of the numerical control system, the servo motor, the worm gear pair, and the act...
