Claims (10)

  1. A bearing housing (1) comprising a bearing housing body (2) for receiving a rotating shaft, and two or more bearing housing legs (4) for attaching the bearing housing (1) to a base (10), wherein the bearing housing body (2) comprises a fixed bearing housing body (2a) and removable bearing housing covers (2b, 2c), wherein the removable bearing housing cover (2b) surrounds the outer end for receiving the rotating shaft, or the removable bearing housing cover (2c) includes an opening into which a shaft is inserted, through which the rotating shaft is inserted during operation, and each of the two or more bearing housing legs (4) extends from the fixed bearing housing body ( 2a ) by an arm (6), and the two or more bearing housing legs (4) are the only parts of the bearing housing (1) that are in contact with the base (10).
  2. The bearing housing (1) according to claim 1, wherein the arm (6) is formed as a polyhedron having a tip (8).
  3. The bearing housing (1) according to claim 2, wherein the polyhedron is a triangular prism, a quadrangular prism, a pentagonal prism, or a hexagonal prism.
  4. The length of the two or more bearing housing legs (4) is substantially longitudinal with respect to the opening that receives the rotating shaft, and/or substantially perpendicular to the direction of the base (10) to which the bearing housing (1) is attached, according to any one of claims 1 to 3.
  5. The bearing housing (1) according to claim 2, claim 3, or claim 4 (as a dependent of claim 2 or 3), wherein the tip (8) of the polyhedron faces toward the base (10).
  6. The bearing housing (1) according to any one of claims 1 to 5, wherein each of the two or more bearing housing legs (4) includes a seal between each of the two or more bearing housing legs (4) and the base (10).
  7. The bearing housing (1) is made from a plastic material, as described in any one of claims 1 to 6.
  8. The bearing housing (1) according to claim 7, wherein the plastic material is selected from polypropylene material.
  9. Use of the bearing housing (1) according to any one of claims 1 to 8 in environments with high hygiene requirements, high cleaning requirements, and/or environments where low adhesion or low accumulation (or no adhesion or accumulation) of dust, dirt, microbial substances, and/or allergens is acceptable.
  10. Use of the bearing housing (1) according to any one of claims 1 to 8 in the food manufacturing industry, the feed manufacturing industry, and/or the pharmaceutical industry.

Description

This invention relates to a bearing housing for use in environments where environmental hygiene is of paramount importance. In particular, this invention relates to a bearing housing for use in environments where environmental hygiene is of paramount importance in order to suppress or even avoid the adhesion or accumulation of dust, dirt, microbial matter, or allergens on, inside, or around the bearing housing. Over the past decade, the food and beverage industry has experienced a significant increase in the number of products that need to be recalled due to contamination by microorganisms, allergens, or dust that were not intended to be present in food products. In this regard, bacterial contamination and unlabeled allergens together account for approximately 75% of the top FDA food recall causes based on the unit. Many companies have established strict safety guidelines and measures in their manufacturing zones to protect food products. These may include measures such as postings recommending handwashing or the purchase of hygienically designed "food-grade" machinery. The increase in recalls has made proactive food safety a top priority for food and beverage control boards, and various different approaches are being used to reduce or avoid contaminated food products. One approach is to manage food products and production lines, but this is highly undesirable for manufacturing because inspections are time-consuming and costly. Inspections may result in the shutdown of the process line until equipment and facilities are properly cleaned. This clearly has a strong impact on production turnover in terms of downtime and the absence of product manufacturing. Figure 1 shows the rear of four different types of the hygienic bearing housing (1) according to the present invention, as defined by Figures 1a, 1b, 1c, and 1d. The bearing housing (1) comprises a bearing housing body (2) for receiving a rotating shaft (not shown in Figure 1) and two or more bearing housing legs (4) for mounting the bearing housing (1) to a base. Each of the two or more bearing housing legs (4) extends from the bearing housing body (2) by an arm (6).Figure 2 shows the front side of the hygienic bearing housing (1) according to the present invention. The bearing housing (1) comprises a bearing housing body (2) for receiving a rotating shaft (not shown) and four bearing housing legs (4) for attaching the bearing housing (1) to a base. Each of two or more bearing housing legs (4) extends from the bearing housing body (2) by an arm (6).Figure 3 shows a hygienic bearing housing (1) according to the present invention. The bearing housing (1) comprises a bearing housing body (2) for receiving a rotating shaft (11) and four bearing housing legs (4) for attaching the bearing housing (1) to a base. Each of two or more bearing housing legs (4) extends from the bearing housing body (2) by an arm (6). Figure 1a shows a bearing housing (1) with two bearing housing legs (4). The two bearing housing legs (4) are oriented longitudinally with respect to the direction of the rotating shaft inserted into the bearing housing (1). Figure 1b shows a bearing housing (1) with four bearing housing legs (4). The four bearing housing legs (4) are oriented longitudinally with respect to the direction of the rotating shaft inserted into the bearing housing (1). Figure 1c shows a bearing housing (1) with two bearing housing legs (4). The two bearing housing legs (4) are oriented perpendicularly to the direction of the rotating shaft inserted into the bearing housing (1). Figure 1d shows a bearing housing (1) with three bearing housing legs (4). The three bearing legs (4) are oriented longitudinally with respect to the direction of the rotating shaft inserted into the bearing housing (1). Figures 1a, 1b, and 1c show bearing housing legs (4) arranged symmetrically around the bearing housing base (2). Figure 1d shows a bearing housing (1) with three bearing housing legs (4), which are arranged asymmetrically around the bearing housing base (2), with one bearing housing leg (4) attached to the bearing housing body (2) via one or more other bearing housing legs (4). Preferably, annular connection portions can be provided for the bearing housing legs (4) (see Figure 1d). In Figure 1, it is shown that the bearing housing legs (4) are longer than the height of the arms (6) (measured from the top (4a) of the bearing legs to the base (4b) of the bearing legs). In fact, the bearing housing legs (4) are the only parts of the bearing housing that come into contact with the base when the bearing housing (1) is mounted to the base. Since the bearing housing base (2) and arms (6) do not come into contact with the base when mounted, the resulting space between the bearing housing body (2) (and arms (6)) and the base (when mounted) allows for easy access to clean the bearing housing from any angle. The bearing housing body (2) includes a fixed bearing housing body (2a) connected via an a
