Description
Technical Field
The present invention relates to a powered drive system, and more particularly to a drive device for driving a drum.
Background
There are existing processing apparatuses having a rotary drum like a rotary cage, a drum, a rotary boiler, etc., and a rotary motor having a rotary shaft is generally used as a driving device. If the rotary drum is a long cylindrical drum with a larger length, especially a long rotary drum formed by connecting a plurality of rotary drums end to end, a long rotary shaft with a larger length is correspondingly adopted as a connecting part for transmitting power between the long rotary drum and the rotary motor; however, the long rotating shaft is difficult to effectively ensure coaxial concentric operation, the problem of uneven power distribution of driving force is easy to occur, and the driving force is easy to wear; and the driving wheel connected with the driving wheel is easy to slip, so that the working stability of the equipment is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a stable, even rotary drum drive arrangement of drive to improve equipment job stabilization nature.
Rotary drum drive arrangement, set up in the transmission ring of rotary drum outer wall department including two or more, have quantity and the unanimous driver of transmission ring in addition, install the drive wheel in the pivot of each driver respectively, each drive wheel offsets with the transmission ring respectively.
The rotary drum driving device comprises a driver and a device main controller, wherein the driver comprises a servo motor provided with an encoder, and the device main controller is used for controlling the servo motor to work.
Rotary drum drive arrangement, install the drive wheel on the driver respectively with each driving ring on the rotary drum relatively and support tightly. The equipment main controller sends a pulse signal to the servo motor according to the working parameters, the servo motor operates according to the set requirement, and the encoder acquires real-time operation data and feeds the real-time operation data back to the servo motor, so that a closed loop is formed to control the speed; each servo motor synchronously drives each driving wheel to rotate, and then the friction force between the driving wheels and the transmission ring drives the rotary drum to rotate. The rotary drum driving device applies driving force to different parts of the rotary drum through the plurality of drivers respectively so as to drive the whole strip-shaped rotary drum to rotate, so that each section of the rotary drum can keep consistent rotating speed, and the phenomenon that the rotary drum is distorted and deformed due to speed difference among the sections is avoided; the working process is quick and uniform, and the working stability of the whole rotary drum can be improved.
