  • Oil seal
    Patent number: 10371260
    Abstract: A slinger of an oil seal has a thread groove carrying out a pumping action toward a diametrically outer side in an external side end surface of a flange portion. A lip seal member has a main lip, a rubber-like elastic dust lip and a rubber-like elastic intermediate lip. The intermediate lip directs a lip end to a machine inner side, comes into close contact with the slinger over a whole periphery with the lip end, and has annular first projections and circumferentially partial second projections in a facing portion to the slinger. The first projection has a structure which makes dust hard to pass through to the lip end by forming a micro gap in relation to the slinger. The second projection has a structure which properly keeps the micro gap under generation of eccentricity in a rotary shaft by having a higher portion than the first projection.

  • Seal structure of crawler-driving apparatus
    Patent number: 10370047
    Abstract: A seal structure is provided to block a clearance between a rotational casing and a fixed housing for driving a crawler of a crawler vehicle. A seal ring is held in a first annular holding groove provided in the fixed housing together with a first O-ring that biases the seal ring toward the outside of the first holding groove. A second holding groove having an opening facing the first holding groove is provided in the rotational casing to hold a slide ring having a higher rigidity than that of the seal ring together with a second O-ring that biases the slide ring toward the seal ring. A foreign object such as mud is thereby prevented from invading a gear chamber without increasing a frictional loss.

  • Sealing device
    Patent number: 10352450
    Abstract: The invention provides a sealing device sealing so as to prevent a sealed fluid in a machine inner side from leaking to a machine outer side between a housing and a rotating shaft which is inserted to a shaft hole provided in the housing. The sealing device has a seal flange which is installed to an outer periphery of the rotating shaft, and a seal lip which is installed to an inner periphery of the shaft hole of the housing and slidably comes into contact with the seal flange over an entire periphery. The sealing device includes a thread groove which exerts a fluid pumping action when the rotating shaft rotates. The thread groove is provided at a position which does not intersect a contact area where the seal lip slidably comes into contact with the seal flange over the entire periphery, thereby suppressing generation of static leakage.
