"Storage of pressure rollers, rolls or the like" 5

The innovation relates to a bearing for pressure rollers, rollers or the like in agricultural machines and equipment, in particular sowing machines, according to the generic term of the main claim.

Pressure rollers, rolls and the like are usually held by so-called flange bearings, which are usually made of gray cast iron. The pressure rollers and the like are arranged on the element supporting the pressure rollers, usually a base frame of the land

economic machine.

The known flange bearings have disadvantages because they require a lot of axial space and therefore a large installation space. This leads to problems, especially with rollers with larger working

wide, problems arise if they are also mounted in the middle. In this case, fastening the flange bearings, e.g. using screws, is a time-consuming job. The clearance of the rotating parts, which are closely arranged there, is very limited and stones, etc. can cause jamming.

tions and thus blocking of the pressure rollers.

In addition, the flange bearings used are disadvantageous due to their rigidity, because when working the soil at high speeds and, for example, a stone

is driven over, the high impact load can damage the packer wheels, pressure rollers or the like, or the bearing itself can be damaged.

The innovation is based on the task of storing

Pressure rollers, rollers or similar, especially for seed drills

which enables simplified assembly and also allows the use of shock-absorbing materials.

This task underlying the innovation is solved by the teaching of the characterizing part of the main claim.

solves.

Advantageous embodiments of the innovation are explained in the subclaims.

An important aspect of the innovation is that it is possible to arrange shock-absorbing materials on the bearing, which are arranged between the ball bearing and the carrier holding the entire pressure roller when the bearing is fully assembled, so that a shock-absorbing effect is achieved, through which the

The service life of the actual pressure rollers or the bearing is significantly increased.

An embodiment of the innovation is shown in the drawings below, where

Fig. 1 in an exploded view on

Fig. 2 shows the bearing together with the bearing body in a

partly cut representation,

Fig. 3 shows in an exploded view

the axle equipped with pressure rollers with a bearing and bearing body arranged in front of it

and in a section the base frame acting as a support and

Fig. 4 shows a partial view of an axle provided with pressure rollers, which is arranged on a base frame.

Referring to Fig. 1, 1 represents a bearing that is arranged in a bearing body 2. This bearing together with the bearing body 2 is screwed onto the axle stub 5 of an axle 6 via a screw 3 and a thrust washer 4, whereby a round tubular spacer 7 is used to

to ensure that the bearing body is mounted at the desired distance from the front side of the axis 6.

After fixing the bearing body 2 with the screw 3, the screw connection does not protrude beyond the bearing unit.

Finally, so-called pressure rollers 8 and 9 are arranged on the axle 6, such as those used in seed drills. Of course, these pressure rollers can also be packer wheels, rollers, etc.

Referring to Fig. 2, a partially sectioned bearing body 2 is shown, which contains a ball bearing 1. In a preferred embodiment, the bearing body 2 can consist of a flexible material, for example a correspondingly soft

plastic, such as polyurethane or rubber. The flexible design of the bearing body 2 ensures that impacts on the pressure rollers 8, 9, when they drive over a stone, for example, are cushioned and thereby the overall service life of the pressure rollers as well as

the stock rises.

These damping qualities can be achieved not only by using a flexible material but also by an appropriate geometric design of the bearing body and can lead to

For this purpose, the bearing body has, for example, a cavity 10 which is closed on the side facing the pressure roller 9 by a cover 11, whereby this cover 11 in this embodiment is designed as a thin film and is made of the same material as the rest of the bearing

body. The formation of the cavity 10 results in

a web 12 is formed which can easily deform when pressure is exerted on it.

The bearing 1 itself is sealed as can be seen at 14. 5

The bearing, which is arranged in a simple manner on the axis 6 together with the bearing body 2, is pushed for assembly, e.g. on the base frame, into a receiving pocket 15 shown in Fig. 3, which is open at its downward-facing end and whose side edges and upper edge are closed.

are so that the bearing body 2 can be pushed into this receiving pocket. The bearing body 2 can then be additionally fixed, e.g. by a screw (not shown) or the like. The receiving pocket 15 is arranged on a holder 16, which in turn is attached to the

Base frame 17 of the seed drill or the receiving pocket 15 can also be attached directly to the base frame 17 or another support.

In the embodiment according to Fig. 3, two recording

pockets 15 are arranged offset one behind the other to accommodate the bearing bodies of two axes arranged one behind the other, as can be seen in Fig. 4. In this illustration, the two axes are located directly one behind the other, so that only the front axis is visible. Both axes carry

Pressure rollers 8, 9 and 8a, 9a, respectively, arranged offset from one another.

The orientation of the receiving space of the receiving pocket 15 is such that it is open downwards and diagonally forwards in the direction of travel. This is advantageous because the load on the axle due to the weight of the mounted seed drill is perpendicular to the contact surface. When the pressure rollers run onto a stone on the ground, this force acts approximately horizontally. The resultant of both forces is therefore

a certain angle from the horizontal, whereby

the longitudinal direction of the receiving pocket 15 assumes this resulting angle.

It is particularly advantageous to use the proposed storage in seed drills, which are installed under or in front of the seed drills

Have pressure rollers that work in a narrow strip of soil on the forward-facing line of the individual shares.

It is advantageous if a metal or plastic housing is first arranged in the bearing body 2, into which the

used bearings, such as ball bearings or plain bearings. This makes it possible to replace the bearing easily if it becomes worn.

A particularly advantageous cost reduction can then be

be sufficient if the bearing 1 is cast into the bearing body 2 immediately during its manufacture.
