Description

The invention relates to devices for transporting piece goods and can be used in chain conveyors to compensate for fluctuations in the difference in the pitch of the chains.

The closest to the invention in technical essence and the achieved result is a drive comprising a drive shaft, two sprockets freely mounted on a shaft, and a coupling with rods, transmitting torque from the shaft to the sprockets and allowing them to shift relative to each other.

The disadvantage of the device is low compensating ability, which reduces the reliability of the drive.

The aim of the invention is to increase the reliability of operation.

This is achieved by the fact that in the drive of a double-chain conveyor, including a drive shaft, a compensating device mounted on it and sprockets freely mounted on the drive shaft with elements for coupling with the compensating device, according to the invention, the compensating device is made in the form of an axis fixed on the drive shaft and mounted on it can be rotated gear, and the element for coupling with the compensating device on each sprocket is made in the form of a gear a crown, wherein the drive is equipped with an additional load leveling chains supporting device in the form of rollers mounted to zvez 1

daughters with the ability to interact with the oncoming branches of the chains.

The effect of using the invention is to increase the reliability of operation and, accordingly, the service life of the equipment by about 3 times due to complete compensation for uneven stretching and wear of the chains.

FIG. 1 shows the proposed device, a general view; in fig. 2 - drive, side view.

The drive of the double-chain conveyor consists of sprockets 1 and 2, freely mounted on the drive shaft 3 in bearings k and fitted with gear rims 5, 6 rigidly fixed on them.

On shaft 3, between sprockets 1 and 2, perpendicular to its axis, an axis 7 is fixed, on which gear gear 8 is mounted, which meshes with gear rims 5 6. Shaft 3 has a stop 9 and adjusting nuts 10 for axial adjustment of sprockets 1 and 2 and the J axis. The asterisks 1 and 2 interact with the chains 11, 12, while in front of the asterisks 1 and 2 there are supporting rollers 13 each of which simultaneously interacts with both incoming branches of the chains 11 and 12.

The drive works as follows.

When transmitting torque from the engine to the shaft 3 with sprockets 1 and 2, gear 9 gears, meshed with gear rims 5, 6 is evenly distributed on both sprockets 1 and 2. When drawing out one of the chains of gear gear 8 rotates axis 7 and redistributes the load.

Thus, any fluctuations in the difference in the pitch of the chains 11, 12 compens W0094

The rotation of the gear 8 and, accordingly, the rotation of one sprocket relative to the other, which leads to uniform tension.

The possibility of adjusting the sprockets 1 and 2 and the gear gear 8 allows the gear 8 to be centered relative to the gear rims 5, 6, ensuring their even loading.

The rollers 13, each of which simultaneously interacts with both incident branches of chains 11, 12, allow using their friction with chains to compensate for possible differences in friction losses in the bearing assemblies of sprockets 1 and 2.
