Abstract
A sealed wheel case for use on a vibrating aggregate processing device comprises a housing sized to hold a rotatable wheel supported on a shaft, the housing having a base, a peripheral sidewall, and a cover. The cover includes an aperture adapted to receive therethrough a driven portion of the shaft. A seal is disposed adjacent the shaft and the aperture, and an annular baffle is mounted to an inside surface of the cover and extends into the wheel case. The annular baffle is positioned on the inside surface of the cover to generally surrounding the shaft and the seal, and a plurality of attachment bolts are arranged to secure the housing to the frame.
Claims7
A sealed wheel case for use on a vibratory device for vibrating aggregate material, the vibratory device having a frame and a rotating shaft extending transversely across the frame and having a wheel, a driven portion of the shaft being operatively coupled to a drive system, the sealed wheel case comprising:
- a housing having a base, a peripheral sidewall, and a cover, the housing being sized to receive therein the wheel and further being adapted to house therein a quantity of lubricating oil for lubricating the wheel, the cover including an aperture adapted to receive therethrough the driven portion of the shaft;
- a seal operatively connected to the shaft adjacent the aperture of the cover;
- an annular baffle mounted to an inside surface of the cover and extending into the wheel case, the annular baffle positioned on the inside surface of the cover to generally surrounding the shaft and the seal;
- and
- a plurality of attachment bolts arranged to secure the housing to the frame.
A sealed wheel case for use on a vibratory device for vibrating aggregate material, the vibratory device having a frame and a rotating shaft extending transversely across the frame and having a wheel, a driven portion of the shaft being operatively coupled to a drive system, the sealed wheel case comprising:
- a housing having a base, a peripheral sidewall, and a cover, the housing defining an interior sized to receive the wheel, the housing adapted to hold quantity of lubricating oil for lubricating the wheel, the cover including an aperture adapted to receive therethrough the driven portion of the shaft;
- a seal operatively connected to the shaft adjacent the wheel case aperture;
- annular baffle means for substantially isolating the seal from the interior of the wheel case, the means carried by the housing cover,;
- and
- a plurality of sealed attachment bolts for securing the housing to the frame.
A vibratory device for vibrating aggregate material and comprising:
- a frame;
- a rotating shaft extending transversely across the frame and having a wheel, a driven portion of the shaft adapted for attachment to a drive system;
- a wheel housing, the housing including a base, a peripheral sidewall, and a cover, the housing defining an interior sized to receive a rotatable wheel, the interior adapted to hold a quantity of lubricating oil;
- an aperture through the cover, the aperture adapted to receive therethrough the driven portion of the shaft;
- a seal operatively engaging the driven portion of the shaft and arranged to inhibit lubricant from escaping the interior of the housing;
- an annular baffle carried by an interior surface of the housing and positioned to surround the seal and the aperture, a cylindrical end of the baffle cooperating with the wheel to define an annular gap, the baffle sized to minimize the size of the gap, thereby inhibiting the flow of lubricating oil from the wheel toward the seal;
- and
- a plurality of sealed attachment bolts for securing the housing to the frame.
