Abstract

In a conveyor drive unit of the type where the main conveyor chain 1 is in driving engagement with an auxiliary chain driven by a prime mover, the respective casings (2,5) of the auxiliary chain and of the prime mover are connected by a torsion spring (6) to permit the casing (5) of the prime mover to be angularly displaced about an axis that coincides with the axis of rotation of the sprocket wheel (4) of the auxiliary chain. The sprocket wheel (4) is preferably mounted on a common shaft (7) with a worm wheel 8 meshing with a worm (9) driven by the prime mover. <IMAGE>

As is known, conveyor drives can be divided into two groups. One of the groups is the so-called. These include rigid drives, in which the drive is rigidly connected to the conveyor and conveyor track. Deflecting the conveyor chain in horizontal or vertical ifs results in uneven movement due to the finite partitioning of the chain. The same can be said about the chain drive. Given that the conveyor system can be considered as a flexible system, these equilibria can be considered as propagation

- 2 176976 up. The result is uneven chain movement, which sometimes causes confusion, and the presence of very strong dynamic forces in each case.

The other conveyor type group is the so called. floaters belong. Here, the conveyor and the drive machine are mounted on a common rigid frame guided in a direction by track rollers in a frame fixed to the conveyor track. There are coil springs between the nozzle frame and the fixed frame, which are generally sm'-c.vr coil springs. With this design, the dynamic load of the conveyor chain is reduced in proportion to the masses, but the weight of the drive and the weight of the conveyor are still very significant and cannot be influenced because a given parameter has a given weight. This solution also has the disadvantage that due to the considerable size and weight of the frame and the frame, it is easy to use. cross-conveyor belts would be difficult to fit and thus not used '.

SUMMARY OF THE INVENTION The object of the present invention is to overcome the aforementioned drawbacks and to provide a drive unit, particularly for dependent convex futures, whereby the drive force can follow the cone stroke drive force and where the dynamic forces resulting from the weight of the drive machine and chain drive.

The invention thus provides a drive unit, in particular for driving conveyor belts having an auxiliary chain which is connected to the conveyor chain, an auxiliary chain drive chain and a drive machine.

The essence of the invention is that the spring for rotating the gear housing of the gear unit, preferably a torsion spring, is fixed to the gear housing and the axis of rotation of the gear housing and the axis of rotation of the auxiliary chain drive β & g.

In the present invention, the pivoting mass of the propulsion machine is reduced in the action line of the spring, and this pivoting mass of the reduced propulsion machine is much less than

the drive pin 1 mass combined with mass of chain conveyor

As a result, the drive is able to provide the traction demand with little dynamic force, approximating the ideal.

DETAILED DESCRIPTION OF THE INVENTION

e. Referring to FIG

Figure 1 is a schematic drawing of the four salts of the lake of the invention; Fig. 6A is a sectional view taken along line Λ-A in Fig.

Fig. Látható shows that the drive is arranged in 2 housings. Here, they are driven by drive rollers of the auxiliary chain 3, which are passed through and endlessly conveyed by the wheels 4 of the conveyor chain passing through the housing 2.

The invention is illustrated in FIG. Here, it can be seen that the drive chain 4 driving the auxiliary chain 3 is mounted on a tubular shaft 7 common to the worm wheel 8 of the drive machine 5. In the drive machine 5, the worm gear 8 is provided with a worm gear 9

In the spirit of the invention, the gear housing 5 is secured to the gear housing 2 by a torsion spring 6 which provides a torsion spring which coincides with the axis of rotation of the chain sprocket t. In the embodiment, the torsion spring 6 is arranged in the rain axis 7.

The propulsion unit of the present invention is the lagging moving frame ^x s negro ria + t small in size and weight. If the jtc-orys according to the invention, the cross pin is light. convoy orolmál
