Abstract

The invention discloses a high-precision single-shaft rotary table with an ultra-wide speed range. The rotary table comprises a protective cover, a worktable surface, a main shaft, a high-precision angular contact ball bearing, a bearing locking device, a lifting ring, a base, an alternating current servo motor, a high-precision angular contact ball bearing, a reading head (1), an angle sensor (1), an adjusting shim plate, an angle sensor (2), a reading head (2), a slip ring and a user socket 16. The rotary table is characterized in that modular design is adopted; two sets of angle measuring systems are designed; the two sets of systems share one mechanical table body; the systems are directly driven by alternating-current servo motors, adopt high-precision bearings as supporting structural parts, and therefore, connection is convenient, efficiency is high, safety is considered; and the protective cover is designed on the mechanical table body of the rotary table. The overall design isscientific and reasonable, operation is easy, convenient, flexible and rapid, and the defects in the prior art are overcome.

Description

technical field [0001] The invention relates to the field of inertial test equipment turntables, in particular to a high-precision single-axis turntable that needs to simultaneously ensure that the turntable meets high-precision positioning in a low-speed state and high-speed accuracy and speed stability in a high-speed state. Background technique [0002] The single-axis turntable is a single-axis platform-type multi-functional testing equipment with functions such as position and speed, which can meet the functional testing and experiments of inertial systems and inertial components. The turntable is controlled by an industrial control computer, which has high-precision positioning capability, stable speed, small operation distortion and good dynamic performance. [0003] High-precision positioning capability in low-speed environment, high-speed accuracy and stability in high-speed environment, if the conventional design method is used, two single-axis tables should be des...
