Problems solved by technology

[0002] The design of the traditional drive system is quite complicated. It is necessary to consider the motor, transmission parts, bearings, measuring devices, etc., and these components have their own specifications and standards. Therefore, it is a complicated task to achieve an optimal combination of each other. The structure and size do not match each other to achieve satisfactory results

Embodiment Construction

[0031] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0032] As shown in FIG. 1 , the structure schematic diagram of the direct drive rotary device of the present invention. A direct-drive rotary device provided by the present invention includes: a casing, a direct-drive motor, a bearing and a non-contact grating.

[0033] Among them, the direct drive motor (direct drive motor rotor 110 and direct drive motor stator 150) is connected with the casing 140 to enable the direct drive rotary device to obtain the best driving performance with the most simplified structure; the bearing adopts a high-precision, high-rigidity three-row The cylindrical combined bearing (including: bearing inner ring 120 and bearing outer ring 130) is connected with the casing 140 and the direct drive motor, which ensures the accuracy, stiffness and sensitivity of the output end of the direct drive rotary device; the non-contact grat...

Abstract

The invention provides a direct drive slewer, which comprises an enclosure, a direct-drive motor, a bearing and a nontouch precise circular grating. The direct-drive motor comprises a direct-drive motor rotor and a direct-drive motor stator connected with the enclosure. The direct-drive motor rotor is connected with external output parts and is used to provide drive output. The bearing comprises a bearing inner ring and a bearing outer ring, and is arranged on the direct-drive motor and the enclosure. The nontouch precise circular grating comprises a photoreader and a precise circular grating. The photoreader is arranged on the enclosure. The precise circular grating is arranged on the direct-drive motor rotor or the bearing connected with the direct-drive motor rotor, and is used to survey and control speed and position of the direct-drive slewer.

Description

technical field [0001] The invention relates to the technical field of mechatronics standard devices, in particular to a mechatronics direct drive rotary device. Background technique [0002] The design of the traditional drive system is quite complicated. It is necessary to consider what motors, transmission parts, bearings, measuring devices, etc., and these components have their own specifications and standards. Therefore, it is a complicated task to achieve mutual optimal combination. Structure and size do not match each other and satisfactory results cannot be achieved. [0003] The direct drive motor is a new type of servo motor. Under the control of the servo system, it can output power according to the motion parameters (position accuracy, stiffness, rotation speed, acceleration, torque, etc.) required by the equipment. All transmission parts from the motor to the final output shaft are eliminated, thereby simplifying the structure to the greatest extent and improvi...
