Chassis gear block with three-point mounting, in particular for crane trolleys

For the stress-free fastening of block gears, their three-point mounting is known several times. Should such a thing Transmission are removed, then it is common to hang this in an assembly cable. Hach looser three The connection points of the block transmission must be on the assembly cable hanging gear can be brought into a position suitable for lowering and setting down by special means In addition to the aforementioned special lifting and deflecting devices, the expansion method takes special fixed precautions Undercarriage supporting scaffolding ahead. The whole facility makes the assembly and dismantling of the gear box look cumbersome, lengthy and expensive and requires the use of specially trained and experienced workers.

According to the invention, these disadvantages are avoided by that the gearbox block after loosening 2weier connection points can be swung out around the third connection point in such a way that that it disengages from the chassis and can be placed directly on a carrier that is foreign to the chassis.

In the drawing is an embodiment of the hiring in Basic features shown, namely point 07.54-49 ■ -./.-

Fig. 1 is a side view of a chassis drive with '-der modern facility,

Pig. 2 shows a section through the device according to the innovation according to the line A-B of Figure 1 *

In the 3rd B. on the portal support 1 (Pig. 1) of a crane that has not been lowered any further, stool 2 eats the running wheel 3 supported. With the running wheel iat a ring gear 4 centrally feat connected * The ring gear 4 is in constant engagement with an intermediate wheel 5, which sits firmly on a shaft 6 (Fig. 1,2) which is rotatably mounted in the walls of the stool. The output pinion 7 of the chassis transmission block 8 is in turn in engagement with the intermediate wheel 5. In the present case, the output shaft 9 of the chassis gearbox face 8 carrying the output pinion 7 protrudes through both walls of the stool 2. The lugs 10 of the flange base bearings 11 carrying the output shaft 9 are located in the walls of the stool 2 and are fastened to this by screws 12 »The gearbox look 8 is also held by a bearing pin 13 on the stool 2. In one by the radial distance of the output shaft given by the bearing pin 13 circular path 9, each wall of the S _o hemels 2 is provided with a slot 14 'so that the output shaft can be moved 9 under certain conditions from the walls of the footrest out transversely to their longitudinal direction .

In the normal operating position, the undercarriage gearbox "blocfc" assumes the operating position shown in FIGS. If for any reason it is desired to remove the undercarriage gear unit, a trolley 15 (Fig. 1) is retracted transversely to the direction of travel of the S _{o hemels 2,}
