Description

one

FIELD OF THE INVENTION The invention relates to the modular-trans-port mechanical engineering, namely to vibrating conveyors.

Known vibrational con: fan, including a load-carrying body, driven in oscillating movement of the crank-drive rod.

The purpose of the invention is the elimination of parasitic vertical oscillations of the load-carrying body transmitted from the drive.

This is achieved by the fact that the “a” is a crankshaft for the drive (there are gears running around on a fixed gear wheel with internal gearing, and the end of the connecting rod is fixed on the shaft with the same radius as the radius of the initial circle of the pinion, and the initial radius gear circle is half the radius of the initial wheel.

FIG. I shows the proposed vibratory conveyor, view of the middle part; in fig. 2 - kinematic diagram of the conveyor drive.

Vibrating console contains a load-carrying body, made of two consecutive sections / and 2, supported on iram 3, for example, using a compressor 4. The connecting rods 5 of the drive are hinged at one end on the crankshafts 6 and the other end are connected through conical springs 7 with shipping body. On the crankshafts 6 are fixed gears 8, which are in internal gearing with stationary gears 9. When this

The radius of the initial circumference of gear 8 and the radius of the knee of shaft 6 are two times smaller than the radius of the initial circumference of wheel 9. The crankshafts 6 are spherically connected to carrier 10, the synchronizer gears 11 are seated on their free ends.

When the crankshafts 6 rotate from the engine 12 through the V-belt drive 13, the gears 8 roll around the wheels 9, orient at a given ratio of the radii of the initial circles of the gear wheel and the wheel, the connecting point of the connecting rod 5 to the crankshaft moves along a straight line, making only reciprocating movement

axis parallel to the axis of the carrying body. During the movement of the connecting rod, a force is transferred to the carrying body, equal in magnitude to the elastic force of the conical 7. The rigidity of these springs can be changed by changing the distance between the brackets 14, for example, with the help of a screw tension gauge.
