Roller plate refers to devices used for transporting blanks in metallurgical workshops and, in particular, on continuous metal casting machines.

The design of roller conveyors with group drive of rollers through cylindrical gears mounted on rollers' shafts and interconnected through parasitic gears is known. The shafts of the rollers and parasitic gears are mounted on rolling bearings in a housing made detachable along the axes of the shafts.

However, if it is necessary to transport short workpieces, for example, after cutting them at a station for dispensing a continuous casting machine, a roller table with a split housing makes it structurally impossible to ensure a minimum roller pitch that corresponds to the length of the workpiece.

The purpose of the invention is to reduce the pitch of the rollers.

This is achieved by the fact that one of the two pins of each roller shaft is installed in removable covers secured in bores on one side of the housing, on the other side of which bores are also made in which removable covers are mounted with one of the two bearing bearings installed on them .

Fig. 1 shows the kinematic drive of the roller table; in fig. 2-live rolls, abundant species; in fig. 3 is the same, eli; in fig. 4-drive roller, the cut but the shaft; on phpg. 5-idler roller, shaft cut; in fig. 6 - parasitic gear, cut but the shaft.

The cantilever rollers 1 are mounted on rolling bearings 2, 3. Cylindrical gears 4 are fixed on the rollers of the rollers. The gear wheels 5 connecting the gears of the rollers by gearing are fixed on the shafts 6, mounted on rolling rollers 7,8. One of the shafts 9 roller vyppep drive with fixed on

him driving gear 10.

The drive shaft 9 is connected by a clutch I with a gearmotor 12.

2 shafts of rollers (Fig. 5) on the right side are mounted in removable

the covers 13, which are fixed in the bores of the housing 14 with bolts 15. The diameter of the bores exceeds the diameter of the projections of the gears to provide axial assembly of the rollers of the roller, respectively, performed on the right

side housing. Another bearing 3 of each roller shaft is fixed in a hollow bore of the housing.

The shafts of the ramified gears (FIG. 6) are mounted through a bore on the left side.

Cornus Bearings 7 on the left side of each parasitic gear wheel are mounted in removable covers 16 secured to the body bores with bolts 17. The bore diameter is also larger than the diameter of the projections of the parasitic gear to provide axial frill.

The described constructional implementation allows a significant reduction in the pitch of the rollers, which in this case is limited to the diameter of the gears.

The device works as follows. When the gearmotor is turned on, the torque from the drive shaft, its heads, the gears to it through the parasitic gears is transmitted to the remaining rollers of the rollers, the direction of rotation, which coincides with each other.

The adhesion of the rollers to the ingot being transported is provided by its weight, from which the appropriate drive power is selected. The direction of movement of the ingot on the roller table is shown by an arrow.
