The invention relates to equipment for the movement of goods and can be used to transport products in drive roller tables or conveyors.

The aim of the invention is to increase the life of the roller.

FIG. 1 shows a drive roller, a general view; in fig. 2 and 3 - dis-t ki with external gearing; figure 4 and

5 - the same, with internal gearing; in fig. 6 - the point of connection of the axis with the planet carrier; in fig. 7 is a view A in FIG.

The drive roller includes a housing 1, the shaft 2 of which rests on the bearings 3. A disk 4 is rigidly fixed on the shaft 2, which is in contact along the circumference with the disk 5, is fixed to f freely on the axis

6 entered 7, rigidly connected to the drive sprocket 8, which sits freely on the shaft 2. Axis 6 is made with bald heads and mounted on a carrier 7 with the ability to move and fix in slot 9 in the radial direction of the disks 4 and 5. Drive sprocket 8, the carrier 7 and the discs 4 and 5 are the drive elements of the shaft 2, and the follower. body and body 1. One of the disks is made of elastic material.

The device works as follows.

Moving the axis 6 - along the groove 9, press the disk 5 to the disk 4 (Fig. 2) until the coupling forces between them

And since one of the disks is made of elastic material (in this case, disk 4), it is slightly deformed, thus creating an elastic deformation force. , 40

Moving the axis 6 of the disk 5 until it touches the disk 4 and further, thereby adjusting the rolling friction moment M between the disks during rotation, which should be slightly j greater than the rolling moment Mk between the satellite and the roller body 1.

the force through the carrier 7, the disk 5 is transmitted to the disk 4 and through it to the shaft 2 rollers. The roller causes the satellites on it to move.

If an obstacle occurs in front of the satellite, instead of the operating MK, there is a moment of friction slip M between the satellite and the roller, which in many respects exceeds the MC. In this case, the disk 5, overcoming the effort of rolling friction and elastic deformations M, begins to run around disk 4, since the coefficient of friction of the slide is a bit higher than the coefficient of friction of rolling.

Satellites stop without turning off the conveyor. When the obstacle is removed from the satellite, the forces of elastic deformation and rolling between the disks 4 and 5 become greater than the rolling friction forces between the satellite and the body of the roller. In this case, the disk 5 stops running around the disk 4 and the roller body causes the satellite to move.
