Title:
ROTATING MACHINE FRAME AND TRANSMISSION MECHANISM THEREOF FOR AEROSPACE STORAGE BOX AND PARTICLE TREATMENT INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2018/006693
Kind Code:
A1
Abstract:
Disclosed is a transmission mechanism, comprising a rotating bearing sleeved on a rotator (1), wherein an outer ring of the rotating bearing is fastened to a pin wheel (3); at least two gears (4-1, 4-2) engage with pin teeth of the pin wheel (3) to form a pin tooth transmission; the gears (4-1, 4-2) are connected to a zero backlash speed reducer; and the zero backlash speed reducer is directly connected to output shafts of two alternating-current servomotors controlled by a numerical control system with a double-servomotor driving anti-backlash technology. The transmission mechanism may be used in a rotating machine frame for an aerospace storage box and a particle treatment instrument, the rotating machine frame comprising the rotator (1), wherein the transmission mechanism drives the rotator (1) to rotate, and the front and rear ends of the rotator (1) are respectively provided with a front rotation power base (6) and a rear rotation bracket base (7). The rotating machine frame uses a circle of large-load-bearing rollers to form a load bearing machine base for supporting the rotating machine frame, non-sliding driving and positioning are achieved under the cooperation of the gears or the pin teeth, and the value of a rotation angle is also obtained in a non-sliding manner according to a certain speed ratio of the gears or the pin teeth at the same time.
