摘要： PROBLEM TO BE SOLVED: To provide a wheel bearing device with a seal having improved sealing performance, for maintaining bearing performance over a long period. SOLUTION: A backup seal 13 consists of a core metal 14, and a seal member 15 vulcanized and adhered to the core metal 14 into one unit. The core metal 14 consists of a cylindrical fitting portion 14a pressed and fixed to the end outer periphery on the inner side of an outward member 3, a disc portion 14b extending from the fitting portion 14a to the radial inward direction and put in close contact with the end on the inner side of the outward member 3, and a cylindrical portion 14c in a cylindrical shape extending from the disc portion 14b further to the inner side. An inner diameter ϕB1 of the cylindrical portion 14c is smaller than an outer diameter ϕA1 of a rising plate portion 10b of a slinger 10, and a labyrinth seal C1 is formed in a clearance between the rising plate portion 10b of the slinger 10 and the disc portion 14b of the backup seal 13.

摘要： PROBLEM TO BE SOLVED: To provide a bearing device for an axle which can effectively suppress adverse effect on rotation detection accuracy. SOLUTION: The device is equipped with an inner ring 5a whose inner peripheral surface is taken as a mounting surface onto an axle 2 side and which integrally rotates with the axle 2, an outer ring 5b which is employed by being mounted in an automobile side mounting object part 3 so as to disable rotation around the axle 2, a plurality of rolling elements arranged between the inner ring 5a and outer ring 5b, and a magnetism detection object body ring 10 installed on the ring 5a relatively non-rotatively about an axis and composed of a first detection object part 10p and a second detection object part 10s magnetically not equivalent to each other and alternately formed in a peripheral direction. The outer ring 5b is provided with a body part 5Q forming a bearing outside diameter surface 5f and a mounting engagement part 5e to the automobile side mounting object part 3 projected outward from the bearing outside diameter surface 5f with respect to the body part 5Q. The inner ring 5a takes a part including the mounting surface of the magnetism detected body ring as a body layer 5y. The body layer 5y is made of a low magnetic susceptibility material with a low magnetic susceptibility lower than that of a magnetic steel. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a bearing device for a wheel allowing reduction of weight/size, improvement of sealing performance of a seal and maintenance of bearing performance over a long period. SOLUTION: A backup seal 19 is attached to a base part 6b of a wheel mounting flange 6. The backup seal 19 is constituted of: core metal 20 having a cylindrical part 20a press-fitted into the base part 6b on an inner side of the wheel mounting flange 6; and a seal member 21 integrally joined to the core metal 20 by vulcanization adhesion and having a side lip 21b extended to be inclined outward in the radial direction and formed into a trumpet shape having a distal end part enlarged in diameter. The side lip 19 is brought into slidable contact with an end face 3c of an outward member 3 via a prescribed interference, and therefore, even if the wheel mounting flange 6 and an end part of the outward member 3 are disposed to be separated from each other, the backup seal 19 corresponding to the space therefore can be disposed, and sealing performance of the seal 8 is improved.

摘要： PROBLEM TO BE SOLVED: To realize a structure for being configured to be small with low cost and having a high degree of freedom in design, and having an excellent sealing characteristic for preventing a foreign body entering to the part where an encoder 14 and a rotation detection sensor 13 for detecting a rotational speed are installed.
SOLUTION: A second seal lip 23 is disposed in whole circumference between an edge face 22 in the axis direction of an outer ring 9 that is a rotating side orbital ring and the outer periphery part of a holder member 15a holding the rotation detection sensor 13. Thereby, attachment of foreign bodies such as magnetic substance and the like to the encoder 14 and the rotation detection sensor 13 is prevented. To miniaturize the ball bearing 8 with the encoder and to obtain a degree of freedom in design, the rotation detection sensor 13 is supported separately from a ball bearing 8 with the encoder against non-rotating support axis 3.

摘要： The invention provides a wheel design that incorporates both a shield and seal on both sides of the guide wheel to eliminate direct liquid pressure on the seal. By retaining the lubrication, bearing life is extended, dramatically reducing machine downtime. In the presently preferred embodiment, the combination of a guide wheel with two rubber spring return (RSR) seals in-bound of two shields, increases guide wheel life through the following: The shields prevent the direct force of a high pressure wash-down from reaching the seal directly. There is a non-direct path between the shield and the outer raceway of the guide wheel to allow any trapped liquid to seep back out of the guide wheel. Also, as the guide wheel rotates, any liquid between the shield and seal is spun-out by centrifugal force.
