Description

The invention relates to an arrangement with an agricultural machine, which has add-on parts, and with a flange bearing for mounting such add-on parts, wherein the flange bearing is formed with a first raceway portion and a second raceway portion. The two raceway sections for forming an annular gap are arranged coaxially with each other to a rotation axis. The flange bearing further comprises a plurality of rolling elements, wherein the rolling elements are arranged between the first raceway portion and the second raceway portion in the annular gap. The arrangement with an agricultural machine with a flange bearing as described above is suitable for use in machines for soil preparation and harvesting technology.

Agricultural machines have attachments, such as seed discs, soil testers, as well as bearings for the storage of drive shafts or intermediate shafts of these attachments. These agricultural machines are used, for example, for introducing seed into the soil.

Robust and reliable bearings are essential for the permanent operation of agricultural machinery and a fast and smooth operation in the field. However, such storage has high manufacturing costs.

The publication EP 2664810 A2 describes a bearing unit for agricultural tools with a housing portion and a hollow shaft, which are arranged coaxially to a rotation axis, with two rolling bearings, each having an outer ring, wherein the two rolling bearings are arranged in a receiving space and adapted to the housing portion and the hollow shaft relative rotatably support each other about the axis of rotation, and with two cover plates, which complete the receiving space on both sides.

The US 4,362,344 A describes a sealed ball bearing with punched races, with two punched parts complement each other to form an inner ring and an outer ring of the ball bearing.

The invention has for its object to provide an arrangement with an agricultural machine, which has add-on parts, with a cost-reduced flange bearing. This object is achieved by an arrangement with an agricultural machine with the features of claim 1. Preferred or advantageous embodiments of the invention will become apparent from the dependent claims of the following description and / or the accompanying figures.

The invention relates to an arrangement with an agricultural machine having attachments. The flange bearing is used to store shafts for attachments to an agricultural implement. The attachments are, for example, agricultural tillage tools, in particular a plow disc for a plow machine or a seed disc for a seeder. The flange bearing is preferably designed as a radial bearing.

The flange bearing has a first raceway section and a second raceway section. In this case, the raceway sections are arranged to form an annular gap to each other coaxially to a rotation axis. The first raceway portion is spaced from the second raceway portion, for forming the annular gap, from the rotational axis in the radial direction.

The flange bearing also has a plurality of rolling elements. The rolling elements are arranged between the first raceway section and the second raceway section in the annular gap. In this case, the rolling elements can be rotatably mounted. For example, the flange bearing can be designed as a roller bearing, this is preferably designed as a ball bearing. In particular, the flange bearing is realized as a four-point bearing. These balls are preferably guided cage-free. However, they can also be performed in a cage device, in particular brass or polyamide cages. Even cones, tons or cylinders, such as needles, are possible as rolling elements.

In the context of the invention, a first Flanschaußenteil and a second Flanschaußenteil are provided, wherein the first raceway portion is formed by the first Flanschaußenteil and the second Flanschaußenteil. The flange parts are preferably connected to each other. In this case, the joining may be a form-locking connection to one another and / or fixing together of the first flanged outer part to the second flanged outer part. The first raceway section is thereby formed in several pieces, in particular in two pieces. It can also be provided more than two flange parts.

The flange face members may include mounting locations or interfaces, such as openings, for mounting the first raceway portion to a surrounding structure. The surrounding construction can be an attachment, for example a seed disc device or a plow disc device. The Anmontierstellen or interfaces may be provided for a screw connection with the surrounding construction.

In the context of the invention, a first flange inner part and a second flange inner part are additionally provided, wherein the second raceway section is formed by the first flange inner part and the second flange inner part. In this case, the flange inner parts are in particular connected to each other. In this case, the connection may be a form-locking connection to one another and / or fixing together of the first flange inner part to the second flange inner part. The second raceway portion is thereby formed in several pieces, in particular two-piece. It can also be provided more than two flange inner parts. The second raceway section or the two inner flange parts may have a receptacle for the positive, in the circumferential direction about the axis of rotation, receiving a shaft. This recording can for example be hexagonal or have a hexagonal recording contour.

The Flanschaußenteile and the flange inner parts are formed according to the invention as sheet metal parts. They can be made from especially thin sheets simplified and made to fit. Sheet metal parts can be produced very easily by stretching or deep drawing from blanks, dicing process, stamping process, etc. This results in a very fast production. In addition advantageously, there is a reduction in weight of the / of the raceway section and thus of the entire flangcher. By this embodiment of the two raceway sections also material in manufacturing, in contrast to, for example, a made of a solid piece of material raceway section, can be saved. Thus, the flange flank parts and the flange inner parts can be produced for example by simple punching, which saves costs, material and time in contrast to the above production.

The flange flank parts and the flanged inner parts are preferably integrally formed as such sheet metal shaped parts, e.g. executed by punching. If, for example, flange lugs or holders etc. are provided on the flange flange parts and the flange inner parts as described below, then they are also preferably included with this one-piece production.

By such, at least or exactly two-part design of at least one of the two raceway sections a fast, cost-reduced and easy production of the first and second raceway section is made possible. Advantageously, a cost-intensive, precise production by turning and / or grinding a massively designed annular body can be avoided.

The raceway sections are preferably formed by directly connecting the first flange inner part to the second flange inner part and / or the first flange outer part to the second flange outer part. However, it is not excluded that an interim insert for different purposes is inserted. Is wear on one of the flanges, i. first or / and second flange inner part and / or first and / or second Flanschaußenteil present, it must, in contrast, for example, to a massive training, no longer the entire corresponding raceway section be replaced, but only the relevant flange inner part or Flanschaußenteil. This saves additional costs.

Even when mounting the rolling elements there are enormous advantages. Here, for example, the rolling elements can be arranged or plugged in / in one of the two flange parts, and then to the formation of the second race section, the corresponding Flanschaußenteil be connected. Now, one of the two flange inner parts can be arranged in a simplified manner in the thus formed first raceway section, and thus the second raceway section can be formed on the rolling elements by connecting the corresponding inner flange part. The first and second flange part have for this purpose guide part outer grooves; For this purpose, the first and second flange inner parts have guide part inner grooves which are connected to guide outer grooves and guide inner grooves for the rolling elements. The guide part outer grooves and guide part inner grooves are in particular formed as guide half outer grooves and guide half grooves. The guide outer grooves and guide inner grooves form the so-called raceways for the Wälzköper.

The flanged bearing offers the additional advantage that this can be adapted to accommodate different waves for attachments in a particularly simple and cost-effective manner. For example, only the outer end contour of the first raceway section is changed. This is particularly easy to accomplish in a simply manufactured sheet metal part.

Preferably, the first flange part and the second flange part are and / or the first flange inner part and the second flange inner part are mirror-inverted to each other. Alternatively or additionally, the two inner flange parts and / or the two flange parts may be formed as equal parts. This is particularly inexpensive. In this case, the first flange outer part and the second flange outer part and / or the first flange inner part and the second flange inner part are mirrored at a mirror symmetry plane. The mirror symmetry plane runs quasi in the middle through the rolling element ring. As a result, the first flange outer part and the second flange outer part and / or the first flange inner part and the second flange inner part are designed mirror-symmetrically. This results in advantages in the production, which is thereby greatly simplified.

Preferably, the first Flanschaußenteil and the second, mirror-like formed Flanschaußenteil and / or the first flange inner part and the second, mirror-like design flange inner part are connected in a position-oriented.
