DE8333031U1 - Axle bearing pocket - Google Patents

Description

In technically undersupplied areas of the Third World, particularly in remote agricultural areas, as well as in slums ^and residential areas of rural-tropical urban peripheries, it is _evident that the need for commercial and entrepreneurial activity remains unfulfilled due to a lack of technical equipment or energy to operate rotating tools, or there is a lack of purchasing power to purchase commercially available electrical tools where electricity networks are available.

Help for self-help could consist of "offering a construction element that opens up the possibility for the public" to build a drive device themselves and to operate a business with suitable tools that meets local needs. A device built from such construction parts would have to function robustly without being prone to failure, without money-dependent maintenance and without problems with spare parts, and would have to be repairable or expandable by the public.

To solve this problem, the axle bearing pocket was developed as an industrially prefabricated connecting part to a subframe or chassis,

2. a rotary axis on which tools can be exchanged without _rotation

3. the tool holder / guide stop etc.,

4. the drive source.

The axle bearing pocket fulfils this purpose with properties that are shown in the drawings. Fig. 1 shows the axle bearing pocket in side view, Fig. 2 shows the axle bearing pocket in horizontal section, Fig. 3 and 4 show an example of use for the drive device. Axle bearing pocket placed on a base frame and rotating axis connected to a hard flywheel of the drive shaft in the working position and Fig. 4 in the driving position.

3. Abitandeieheruwg between the »work« and the abutment,

(Seneffect, PUhruwgsenseschlag etc.), 4» Energy transfer to the rotational area is achieved by the A eh· stored &bgr; eh &bgr; as follows«

The teak has two sheet metal parts 2, which are enclosed at three hinge points by a sheet metal frame 3 and leave a teak opening free. The sheet metal frame 3 protrudes all around on both sides as fastening elements for further different structural elements in device construction. The side plates 2 can (as in the example shown) have a treble shape according to the spreading tailing of the base frame, which is inserted into the pocket and is to be ^fastened therein.

In the side panels 2 there is a circular opening 4 arranged for the passage of the axle sleeve 1, which consists of a flat piece. The center point of this opening 4 is also the point of a circular arc on which holes S are arranged for the passage of axle bolts 6, which hold the bearing rollers (single ball bearings) 7 in the correct position as pivot bearings of the axle sleeve 1. A pivot axis β can be pushed through the axle sleeve 1 and secured in it and, with a square cross section, can be made of a squared timber (or square tube) to be manufactured locally for the rotationally fixed securing of slide-on tools.

Cross-connections between two axle bearing pockets parallel to the rotation axis B simultaneously represent abutments or shear edges for the rotating tool.

The axle sleeve 1 can be extended to serve as a pulley for power _transmission from rotors or from wind/water driven transmissions or can be extended to the wheel hub in conjunction with a gear wheel with an end crank as shown in Fig. 3, while according to Fig. 4 the rotating axis B projecting from the work surface serves as a driving axis with the axle sleeve 7.

Claims (2)

It I · · — ti ·*· t · · •It·· ti» ·· » Protection claims 1. Axle bearing pocket as roller bearing and construction part -':' for simple device construction characterized by the fact that an axle sleeve (1) is arranged roller-bearing inside a sheet metal pocket consisting of two sheet metal parts (2) and a sheet metal frame (3) enclosing it on three sides and projecting over the sheet metal sides (2) for inserting and fastening different construction parts, 2. Axle bearing pocket according to claim 1, characterized in that the blank sides (2) are provided with a circular opening (4) and these are surrounded in a circle with the same center point by holes (5) _for receiving axle bolts (6) for bearing rollers or individual ball bearings (7). Furthermore, characterized in that the axle sleeve (1) arranged rotatably in the openings (4) consists of a piece of pipe which is rotatably mounted within the circularly arranged bearing rollers (7) and into which a tool-carrying rotary axis (B) of any cross-section can be inserted or fastened in a rotationally fixed manner.
