The well-known » replaced massive carriage frames with a relatively lightweight roller bearing arrangement that enables the paddle wheel diameter is significantly reduced, and therefore the paddle wheel can be made much easier to earth. The movable carriage on which the Roller bearing assembly and the paddle wheel are attached,

^ does not need to be interpreted in such a way that it is so large Can accommodate mass as before, and the movable carriage can be designed to be less massive than before. That the same applies to the bridge over which the carriage is moved} it is less massive. This means that, viewed as a whole, a far more economical structure is achieved which is expressed in a lower S-fcabl consumption as well as in a lower expenditure of time and equipment for the production of the various elements that make up the bucket wheel excavator. For example, can

The paddle wheel 1o has an enclosing frame 34 which surrounds the bridge% 2 and which is rigidly attached to the carriage 2o. The paddle wheel to is arranged concentrically around the outer part of the surrounding frame 34. The surrounding frame prevents material that is received by the blades or beehives from entering the chambers 12 until a cup and the associated chamber have reached the highest point of the wheel. At this STEL% Ie of the hopper 32 is provided which has dtr an opening in the surrounding frame, through which the blade wheel τοη recorded material to the conveyor 3o for which it can.

The paddle wheel 1o is supported on the frame 34 and let rotatable about this frame with the aid of a ball bearing arrangement 36. The ball bearing assembly 36 preferably has a inner rigid ring 38 and an outer movable ring 4o, | which are separated from one another by balls 42. The races in which the balls are mounted are made of circular rods or wires 44, 46, 48 and 5o. the Race bars 44 and 46 are preferably releasably attached to the inner peripheral surface of the outer movable bearing ring attached. The oppositely arranged rods 46 and 5o bind / similar catfish with the outer circumferential surface of the inner bearing ring 38 attached. From the Pig. 4,6 and 7 ' it follows that the inner bearing ring 38 consists of a pair

Frame 34 in which the screws 68 are also arranged.

How fig. 6 can be seen, the ring gear 28 is attached to the outer bearing ring 4o on the side opposite to the paddle wheel 1o by means of screws 6o offset in the radial direction. The inner, slotted bearing race halves are detachably connected to one another as a unit via ψ screws 56, which are similarly offset in the radial direction around the inner bearing ring 38. From Fig. 5 it can be seen that the various bolts and screws described are arranged on different radii.

From Figures 4, 6 and 7 shows that appropriate seals to prevent lubricant discharge and an exclusion are presented by dirt and moisture g seen. Helical pins 58 (FIG. 1) that are offset in the radial direction and fit exactly into the aligned openings are provided in order to prevent a relative rotational movement between the inner bearing ring halves and 54. The beveled pins 59 serve a similar purpose in that they prevent relative movement between the ring gear 28 and the bearing ring 4o. Various pins 59 are arranged in the radial direction in the ring gear and in the outer bearing ring of the bearing.

Like Pig. 3 shows, the ring gear 28 has internal teeth 29 on, which come into engagement with a motor-driven drive gear, which is attached to the carriage 2o and the Blade wheel 1o over the outer bearing ring 4o a movement granted.

Reference is now made to FIGS. 8 to 12 » The bearing rings 38 and 4o are continuous and in the event that one or both rings are replaced must, the bridge 22 must be provided with a connection 63 that can be opened (Fig.8) so that a Bearing ring can be removed. Therefore, the bridge 22 has overlapped sections that run in the longitudinal direction Form carriers 81, 8o, and 82, as they are generally shown in FIG and shown in detail in FIGS. 9, 10, 11 and 12 are. The beams 80, 81 and 82 are connected by pillars, which form the bridge 22 in the known lattice structure.

From Figs. 9 and 1o it can be seen that the connection 63 is made by adjacent portions of the Carriers 80, 81 and 82 are closed with end plates 86. On the supports 80 and 81 are plates 86 with the horizontal Plates 83 and vertical side plates 84 connected, the plates 83 and 84 take the rails 21 and 24 for guidance and supporting the carriage on, the rails 21 and 24 are

connected to the plates 83, 84 in any desired manner. The plates 83, 84 are

909809/0267

- 15 -1. February 1967 W / T Η / ρ 4896

as FIG. 9 shows, braced by additional plates 91 »92 and 93. The end plates 86, which are screwed together at the connection point 63, are additionally by two Wing end disks 99 braced, which, as shown in FIGS. 9 and 10, are welded. Between the end plates 86 there is a cup plate 1oo in a manner known per se intended.

The lower bracket 82 has a box shape as in FIG. 11 12 and 12, and the end plates 86 of this beam are connected to the box-shaped structural members. Wing end disks 99 are with the end plates 86 and welded to the box-shaped support sections.

The end sections 22 a of the bridge 22 are connected to the central part 22 b of the releasable connections 63. The connections not only make a device for removal and removing bearings, but also provides a convenient arrangement for on-site assembly of factory-assembled parts consisting of a paddle wheel, drive tire, ball bearing ring and surrounding frame

Since at least one connection is required, it follows that the ball bearings in Hingen 38 and 4ο are preferred to roll on their surface, which is continuous in the circumferential direction. The rods or wires 44, 46, 48 and 50

as well as their support members 4o, 52 and 54 are thus not as executed interrupted, ring-shaped elements. However, this results in the following problem when an expansion is required is, these rings and running bars must either be guided over the end frame 65, which is due to the size this frame is not possible, or the connection from the end frame to the bridge must be interrupted, or it Another possibility must be created, which ensures utilization of the advantages of the invention according to camp training. As provided in the case of the invention, in the case of storage, the bridge is lashed, and Figure 8 shows how this overlap enables the element to be assembled and disassembled.

According to Fig. 8, blocks 2oo are under the sections 22 a and 22 b arranged at the level of the overlap. The overlap is then opened. Following this, the end sections 22 a and the associated end frame by lifting or the like. tilted so that the tab connection plate 86 of the end sections 22 a are moved far enough away from the plates 86 of the middle section so that the camp through can pass through the opening. The bearing components are released from the wheel 1o and from the ring gear 28 as well as in the Brought in Fig. 8 position shown before the components are built. The warehouse can be from a lifting device or Like. Be supported.
