摘要： A four-row cylindrical roller bearing is incorporated into between the inner peripheral surface of a housing and the outer peripheral surface of a backup roller. A sensor unit 7 is held in a portion of a collar disposed in the axial-direction end portion of the four-row cylindrical roller bearing. The sensor unit comprises a detect part for detecting temperatures and vibrations and a transmitter device for transmitting signals, which are obtained after output signals taken out from the detect part are processed, as radio signals. On a portion of a hold cover which is a separate member from the collar, there is disposed a receive antenna which is part of a receiver apparatus for receiving the radio signals transmitted by the transmitter device.

摘要： For preloading a tapered roller bearing (1) secured with a conical seat on a tapering roll neck (3) of a roll (2), in particular, a back-up roll, arranged in a roll stand by means of a chock (4), by application of a hydraulic pressure thereto, the bearing inner ring (18), rollers, (17) and the bearing outer ring (17) of the tapered roller bearing (1) are subjected to pressure produced during rolling and are radially preloaded against the roll (2). An annular pressure-applying device is supported on the roll (2) by an axial bearing provided on the roll end neck, is arranged against the bearing outer ring of the tapered roller bearing (1) and, upon application of pressure, displaces the chock (4) with the bearing outer ring (13) in a direction toward the roll body (15) or the roll (2) in an opposite direction.

摘要： A four-row tapered roller bearing is incorporated in the clearance between the inner surface of a housing and the outer surface of a rolling roller. A pair of supporting members supporting sensor devices are fitted in and supported by a part of the inner surface of the housing in such a manner that they are opposed to the ends of outer rings of the four-row tapered roller bearing disposed close to the both axial ends thereof. The sensor devices each comprise a distortion gauge as a detecting portion and a first coil for transmitting as a wireless signal a signal obtained by processing an output signal outputted from the distortion gauge. A second coil for receiving the wireless signal transmitted by the first coil is retained on a part of a member other than the supporting members.

摘要： When an inner race 12 rotates at a speed lower than a predetermined speed, a sealing body 27 contacts the sealing face part 21c, but when the inner race 12 rotates at a speed more than the predetermined speed, a contacting pressure to a sealing face part 21c is reduced or the sealing body 27 is isolated so as to form a non-contacting seal, and therefore, for example, at the low speed, the sealing body 27 forms a contacting seal, thereby to compensate a low speed-low sealing ability of the non-contacting seal such as the labyrinth seal, and on the other hand, at high speed rotation, the sealing body 27 reduces the contacting pressure to the sealing face part 21c, otherwise separates therefrom to form the non-contacting seal as the labyrinth seal, whereby it is possible to solve the problem of heating or abrasion at the contacting part. Further, a sleeve 122 is mounted on the supporting edge 12a of the inner race 12, thereby to secure the sealing device 120 without processing a screwing hole in the inner race 12. Moreover, the sleeve 122 is optionally processed with a screwing hole 122a, to thereby easily fix the sealing device 120 by the bolt 124.

摘要： A sealed rolling bearing in which a rolling member is disposed in a bearing space formed between an outer race and an inner race to rotate the outer race and the inner race relatively to each other, and rotation seal members are disposed at both ends of the bearing space in the axial direction thereof while a stationary seal member is disposed on the side of the inner race, thereby sealing the bearing space. The bearing is provided with a vent on the side of the inner race for approximating a fluid pressure in the bearing space to an outside fluid pressure by causing the inside of the bearing space to communicate with the outside when the state of fluid in the bearing space and state of the outside fluid have a predetermined relationship.

摘要： A formed film is formed on the surface of a metal substrate made of an iron-based metal. Thereafter, the surface of the formed film is subjected to treatment for lessening surface roughness such as rolling. In this arrangement, a member which exhibits a sufficient seizing resistance even after being freed of formed film can be obtained.

摘要： A roll supporting device for a rolling mill arrangement, supporting rolls rotatably to housings by double row roller bearings or multi-row roller bearings. On surfaces of bearing rings and rollers of the roller bearing are provided carbonitrided layers of 0.80% or greater in carbon content and of Rockwell hardness HRC 58 or greater. The carbonitrided layers are formed to contain residual austenite content of 25-30% by volume. By virtue of the carbonitrided layers, the strength against the surface-initiated type damage to the contact surfaces of the bearing rings and the rollers is improved, so that the enhancement of the life of the roll supporting device, especially the lives of the bearing portions thereof, can be achieved to contribute to the prolongation of inspection and maintenance periods and to the reduction of inspection and maintenance costs.

摘要： In order to appropriately distribute a lubricating oil of high viscosity to lubrication points through a simple construction in oil and air lubrication, in a preferred embodiment of the present invention, three distributors 8, 9 and 10 are provided between oil feed passages 7, the most downstream one of which is connected at the downstream end of the passage to a fourth branch passage 14. Quantities of the lubricating oil are passed through the holes A, B and C of the first distributor 8, those E and F of the second distributor 9 and that H of the third distributor 10. Other quantities of the oil, which are nearly equal to each other, are sent to three lubrication points through the other holes D, G and I of the distributors 8, 9 and 10 and a first, a second and a third branch passages 11, 12 and 13. The three lubrication points are a point at contact-type oil seals 5, and two points in a four-train conical roller bearing 3. The oil flowing through the oil feed passage 7 downstream of the third distributor 10 is all sent to the other lubrication point at contact-type oil seals 6 through the fourth branch passage 14.

摘要： A mechanism for converting rotary motion in rectilinear to and fro comprising and hinged in the housing of a crosspiece by a prestressed rod and conical bearing. An even number of bearings stacked symmetrically on each side of the center and internal cages are fitted an intermediate bush with the interposition of spacing rings, the thicknesses of the rings being so determined that the pre-stressing force is distributed equally between the bearings and causes the complete take-up of play. The invention is particularly useful in multicylinder pump mechanisms distributed regularly around a shaft and with axial pistons.
