Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hollow integrated servo joint module structures, and specifically relates to a hollow integrated servo joint module structure. Background Technique
[0002] A hollow integrated servo joint module structure is a highly integrated integrated design modular joint, which has various technical characteristics and advantages, and is widely used in multiple fields such as robots and automation equipment. Moreover, the hollow integrated servo joint module structure integrates multiple key components together, reducing the connection and assembly work between components and improving the integrity and reliability of the system.
[0003] Currently, the servo joint modules in the prior art do not adopt a hollow structure and adopt side wiring, which will occupy the external or additional space of the module. This is disadvantageous for application scenarios with limited space. Side wiring requires more space to be reserved around the module to accommodate cables and connectors, which will increase the volume and weight of the entire system. In view of this, we propose a hollow integrated servo joint module structure. Content of the Utility Model
[0004] The main purpose of the utility model is to provide a hollow integrated servo joint module structure, which can solve the problems proposed in the above background technique.
[0005] To achieve the above purpose, the utility model proposes the following technical solutions:
[0006] A hollow integrated servo joint module structure includes a housing. A harmonic reducer is provided below the housing. The harmonic reducer includes a wave generator, a flexspline body, and a circular spline. A central tube is provided inside the housing, and the harmonic reducer is sleeved with an integrated central shaft.
[0007] Preferably, a driver body is provided at the top of the integrated central shaft, and the integrated central shaft is detachably connected to an integrated motor.
[0008] Preferably, a high-speed bearing sleeve and a crossed roller bearing are sleeved outside the integrated central shaft. A brake is embedded in the high-speed bearing sleeve, and an output plate is fixedly connected to the side wall of the crossed roller bearing.
[0009] Preferably, the driver body is detachably connected to a driver flange.
[0010] Preferably, a flexspline end cover is provided above the flexspline body, and the integrated central shaft is sleeved with a low-speed coding flange and a high-speed coding flange.
[0011] Preferably, a square hub, a ball bearing retaining ring, a single-row deep groove ball bearing, and a flexible bearing are sleeved around the outer wall of the integrated central shaft. Through the setting of the central tube, the extra occupied space outside the module is effectively reduced, and at the same time, the overall module is made more aesthetically pleasing. Also, the overall volume and weight of the module are reduced. Moreover, with the integrated motor as the main power source, rotational power is generated through electromagnetic induction. Then, the rotational power of the integrated motor is transmitted to the entire servo joint module through the integrated central shaft. Next, through the interaction of the flexspline body, the circular spline, and the wave generator in the harmonic reducer, a large reduction ratio and high torque output are achieved. The rotational power of the integrated motor is further transmitted to the servo joint module through the output plate. Then, the position and speed of the rotating shaft are monitored in real time through the low-speed coding flange and the high-speed coding flange, and this information is fed back to the driver body. The driver body adjusts the output of the integrated motor according to the feedback signal to eliminate errors, thereby achieving precise position and speed control. Secondly, when it is necessary to stop the rotating shaft, the brake will quickly engage, thus ensuring the stability and safety of the servo joint module.
