Three forced synchronism vibrators
Technical field:
The utility model relates to the generation or the transmission of mechanical oscillation, particularly a kind of three forced synchronism vibrators that are used on the elliptically vibrating screen.
Background technology:
At present, three forced synchronism vibrators on the large-scale elliptically vibrating screen are to be made of one three shaft vibration device and three synchronizeds, and its vibrator and synchronized are installed in respectively in two casings, connect through shaft coupling between two casings.The shortcoming that this split-type structural exists is a complex structure, and volume is big, and Heavy Weight has improved the various costs of production, transportation, installation and work operation.
Summary of the invention:
The purpose of this utility model be design a kind of simple in structure, volume is little, in light weight, produce, transportation, install and three low forced synchronism vibrators of the work various costs of operation.
The technical solution of the utility model is finished as follows, it includes one three shaft vibration device, it is characterized in that: each centre is corresponding respectively in the casing of three shaft vibration devices is equipped with a gear that diameter is identical, word engagement arranged side by side in casing between each gear.Stagger inside and outside the position of eccentric block on the position of eccentric block and two side shafts on the jackshaft.
The utility model is installed in three pitch wheels respectively in the middle of three axles of vibrator, a synchronized casing and shaft coupling thereof have been reduced, make structure more reasonable, have little, the lightweight advantage of volume, production, transportation, installation and the various costs of work operation reduce greatly.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is to adopt one three shaft vibration device, keep the installation relation of each eccentric block 3, casing 1 and bearing 4 constant, improvements are gears 5 that an equal diameters is installed respectively in the centre of casing 1 interior three axles 2, word engagement arranged side by side in casing between each gear, form a cover forced synchronism mechanism, guarantee the run-in synchronism of each eccentric block and power transmission shaft 2, elliptical trajectory is operated steadily.In order to make this vibrator compact conformation, stagger inside and outside the position of eccentric block on the position of eccentric block and two side shafts on the jackshaft.
