CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    The present application claims benefit of U.S. Provisional Patent Application No. 61/701,229 filed Sep. 14, 2012, entitled OIL SLINGER MOUNTING ARRANGEMENT, which is incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present disclosure generally relates to oil slingers, and more particularly, but not exclusively, to oil slingers mounted to a rotary shaft. 
       BACKGROUND 
       [0003]    Rotor systems, such as blowers, that effectively use oil slingers remain an area of interest. Some existing systems have various shortcomings, drawbacks, and disadvantages relative to certain applications. Accordingly, there remains a need for further contributions in this area of technology. 
       SUMMARY 
       [0004]    One embodiment of the present invention is a unique oil slinger. Other embodiments include apparatuses, systems, devices, hardware, methods, and combinations for an oil slinger. Further embodiments, forms, features, aspects, benefits, and advantages of the present application shall become apparent from the description and figures provided herewith.

     DETAILED DESCRIPTION 
       [0009]    For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications in the described embodiments, and any further applications of the principles of the invention as described herein are contemplated as would normally occur to one skilled in the art to which the invention relates. 
         [0010]    With reference to  FIGS. 1-4 , an oil slinger  10  attached to a rotating shaft is provided. Generally, the oil slinger  10  is mounted to a rotating shaft, and more particularly, the oil slinger  10  is mounted to the shaft  14  of a blower  18  in a removable fashion using a compression type fitting. In one embodiment, the oil slinger  10  is secured to an oil slinger hub  22  via screws, and the oil slinger hub  22  is placed onto a tapered section of a slotted adapter sleeve  26  surrounding the rotor shaft  14 . A lock nut  30  and retaining element  34  are then screwed over the narrow diameter end  38  of the sleeve  26  , where the slot of the sleeve is widest, to press the slinger hub  22  up the taper  42  of the sleeve  26 , thereby compressing the sleeve  26  onto the shaft  14  and securing the slinger hub  22  to the sleeve  26 . An advantage of this mounting arrangement is that the oil slinger  10  is less likely to become loose during use (e.g., due to thermal shifts) while still permitting disassembly for purposes of service or reuse. 
         [0011]    One example aspect of the present disclosure provides an apparatus having a rotatably mounted shaft  14 , an adapter sleeve  26 , a hub  22 , an oil slinger  10 , a lock nut  30 , and a retaining element  34 . The shaft  14  may be rotatably mounted in any known fashion such as by, for example, a bearing  46 . The adapter sleeve  26  is mounted about or coupled to the shaft  14  and has a tapered or frustoconical outer surface  42 . A narrower end  38  of the adapter sleeve  26  is mounted toward a first end  50  of the shaft. The hub  22  is mounted about the adapter sleeve  26  and has a frustoconical inner surface  54  that mates with the frustoconical outer surface  42  of the adapter sleeve  26 . The hub  22  is further provided with two sections, where a first section  58  has a radial dimension that is smaller than a radial dimension of the second section  62 . The oil slinger  10 , which has at least one radial dimension larger than the second section  62  of the hub, is mounted to the hub adjacent the second section  62  and about the first section  58 . The oil slinger  10  is fixedly attached to the second section  62  by fasteners such as, for example, threaded fasteners such as, for example, one or more screws  66 . The lock nut  30  is mounted about the adapter sleeve  26  adjacent to the first section  58  of the hub  22 . A retaining element  34  may also be provided disposed between the hub  22  and the lock nut  30 . The adapter sleeve  26  may have a slot  70  that is generally parallel to the longitudinal axis of the shaft  14  for retaining the retaining ring  34 . In addition, a rotor  18  may be mounted to an end of the shaft  14 . 
         [0012]    While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiments have been shown and described and that all changes and modifications that come within the spirit of the inventions are desired to be protected. It should be understood that while the use of words such as preferable, preferably, preferred or more preferred utilized in the description above indicate that the feature so described may be more desirable, it nonetheless may not be necessary and embodiments lacking the same may be contemplated as within the scope of the invention, the scope being defined by the claims that follow. In reading the claims, it is intended that when words such as “a,” “an,” “at least one,” or “at least one portion” are used there is no intention to limit the claim to only one item unless specifically stated to the contrary in the claim. When the language “at least a portion” and/or “a portion” is used the item can include a portion and/or the entire item unless specifically stated to the contrary. 
         [0013]    Unless specified or limited otherwise, the terms “mounted,” “connected,” “supported,” and “coupled” and variations thereof are used broadly and encompass both direct and indirect mountings, connections, supports, and couplings. Further, “connected” and “coupled” are not restricted to physical or mechanical connections or couplings.
