Problems solved by technology

[0003] The existing drive often adopts the traditional "rotary motor acceleration and decelerator" method. Due to the existence of the deceleration transmission link, the error caused by the gear clearance cannot be avoided, which reduces the dynamic performance of the turntable; and due to the existing in the traditional mechanical transmission link Friction, mechanical vibration, noise, wear, etc. will not only affect the dynamic performance and positioning accuracy of the turntable, but also produce oil, particles and other pollutants
In addition, due to the impact of the rotor structure on the existing direct-drive turntable due to machining accuracy, error accumulation, assembly clearance, etc., the rotor will appear radial runout to varying degrees during use, which in turn affects the smoothness of the motor rotor operation
Moreover, the above-mentioned existing structure has hidden dangers such as great difficulty in processing and assembling, and many uncertain factors.

Abstract

A direct-driven rotary table. The rotary table includes a linear motor stator and a pushing rod, and also includes an operating mechanism, a pedestal, and a movable sleeve, a rotating motor rotor two ends of which are provided with supporting seats and a rotating motor stator which are arranged outside the linear motor stator in sequence. The direct-driven rotary table provided by the invention has the advantages of high work efficiency and positioning accuracy, firm, simple and compact structure, convenient assembling and disassembling and later maintenance.

Description

technical field [0001] The invention relates to a turntable, in particular to a direct drive turntable. Background technique [0002] The turntable that converts electrical energy directly into mechanical energy to drive the load without passing through any intermediate conversion device is a direct drive turntable. This structure has the advantages of high working efficiency and good transmission efficiency. [0003] The existing drive often adopts the traditional "rotary motor acceleration and decelerator" method. Due to the existence of the deceleration transmission link, the error caused by the gear clearance cannot be avoided, which reduces the dynamic performance of the turntable; and due to the existing in the traditional mechanical transmission link Friction, mechanical vibration, noise, wear, etc. will not only affect the dynamic performance and positioning accuracy of the turntable, but also produce oil, particles and other pollutants. In addition, because the ro...
