¿Qué es un disco giratorio? Clasificación y aplicación de la unidad de giro.
El reductor giratorio es un reductor giratorio con una fuente de alimentación de impulsión integrada. El rodamiento giratorio se utiliza como parte principal de la transmisión y como accesorio del mecanismo. Su esencia es un motor de imán permanente con un gran par. Este producto también se llama reductor rotatorio. Drive, en comparación con los productos rotativos tradicionales, tiene una instalación simple, fácil mantenimiento y ahorra espacio de instalación en mayor medida. Se utiliza principalmente en camiones con vigas, vehículos de trabajo aéreo, robots industriales, generación de energía fotovoltaica, generación de energía eólica y garras de maquinaria de construcción. Herramientas y otros campos.
¿Qué es la unidad de giro?
1. Definición de unidad de giro
The slewing drive device is also called a slewing reducer, a gear reducer, a turntable reducer, a slewing mechanism, and a slewing drive pair. They are all types of reducers that use slewing bearings as the main support, and the auxiliary drive source uses gears or worms as the driving parts, so as to realize the deceleration and full-circle slewing functions. The composition of the slewing drive mainly includes gears (or worms), slewing bearings, motors, housings, and bases. Slewing drive can be basically divided into single worm drive slewing drive, double worm drive slewing drive and special type of slewing drive.
2. Classification of slewing drives
(1) Classification according to transmission form
According to the variable transmission form of slewing drive, it can be divided into gear slewing drive and worm gear slewing drive, inheriting the characteristics of gear drive and worm gearing. These two slewing drives can be adapted to medium-high and low-speed applications respectively. In terms of carrying capacity, the performance of the worm gear type is better than that of the tooth type, and when the envelope worm transmission is adopted, its carrying capacity, anti-deformation ability and transmission rigidity are further improved, but the worm gear type rotary drive is more efficient in terms of efficiency. Inferior to the gear type slewing drive, the gear type slewing drive is divided into a straight tooth type slewing drive, a helical tooth type slewing drive, and a volute type slewing drive.
(2) Classification according to the openness of slewing drive
According to the openness of the slewing drive transmission mechanism, the slewing drive can be divided into open and closed. Generally, the open structure is mostly used in applications where the environment is too harsh and the maintenance and maintenance cycle is short. The open structure is more convenient for parts. The inspection, maintenance and maintenance of the product are also more convenient for replacement. However, the closed structure can provide a longer maintenance life cycle in occasions where the environmental conditions have not changed much and the environmental pollution level is below the medium level.
(3) Classification according to driving power
According to the structure operation type of the slewing drive, it can be divided into light slewing drive, medium slewing drive and heavy slewing drive. According to the slewing drive’s power, size, dead weight, and application in different fields and machines to achieve its own functions, the light-duty slewing drive is light in weight, and its load and deceleration capabilities are suitable for high-speed (≥10rpm), vibration, impact loads, etc. Working conditions: The medium-sized rotary drive is suitable for high-speed (≥10rpm), vibration, impact load and other working conditions, and the heavy-duty rotary drive is suitable for high-speed (≤3rpm), heavy-duty, and intermittent working conditions.
(4) Classification according to the drive composition structure
Según la composición del dispositivo de accionamiento, se divide en accionamiento vertical y accionamiento de giro horizontal. La transmisión de giro vertical significa que el motor de tracción y la rueda motriz son verticales, y el motor de tracción está en posición vertical sobre la rueda motriz. Tiene las ventajas de un radio de giro pequeño, un alto nivel de protección, un mantenimiento conveniente, etc., pero un alto costo de fabricación; accionamiento horizontal significa que el motor de tracción y la rueda de desplazamiento son paralelos, y el motor de tracción es principalmente coaxial con la rueda de desplazamiento y es horizontal. Tiene las ventajas de estructura compacta, simplicidad y baja altura de instalación.
