摘要： A system and method for monitoring wheel hub temperatures and odometry in trailer axles. The system includes a spindle (118), an inner bearing (114), an outer bearing (116), a wheel hub (106) engaging the spindle (118) via the inner and outer bearings (114, 116), a thermocouple (108) positioned within the spindle (118), and an electronic control unit (112). The electronic control unit (112) is electrically coupled to the thermocouple (108) and configured to receive from the thermocouple (108), a temperature signal. The electronic control unit (112) is configured to determine, from the temperature signal, a temperature. The electronic control unit (112) is configured to compare the temperature to a predetermined threshold. The electronic control unit (112) is configured to, when the temperature exceeds the predetermined threshold, indicate a fault.

摘要： A tapered roller bearing includes an inner ring with a large rib, an outer ring, and multiple tapered rollers. Each of the tapered rollers has, at its axial end, a large end face that is a convex surface. The large rib has a rib face that is a concave surface and that is in contact with the large end face. When a distance from a position of contact between the large end face and the rib face to a cone center of the corresponding tapered roller is defined as R, a curvature radius of the large end face is defined as Rr, and a curvature radius of the rib face is defined as Ri, an inequality represented by 2≤(Ri −R)/(R−Rr)≤10 is satisfied, where Rr

摘要： A sealing device for a bearing unit, where the unit has a radially outer ring, two rows of rolling bodies arranged, respectively, between the radially outer ring and a pair of radially inner rings. The sealing device further provides a spacer including an annular groove and configured to be arranged between the radially inner rings of the bearing unit and a seal housed inside the groove of the spacer. The seal is “U” shaped, defines a volume internally and is configured to be mounted in the annular groove with the concavity directed towards the axis of symmetry of the bearing unit.

摘要： A fuel-saving apparatus using a variable preload of vehicle bearings is provided. The fuel-saving apparatus includes a housing that supports a driving shaft of a vehicle, a bearing that is mounted in the housing and rotatably supports the driving shaft, and a variable preload unit that is provided at the housing or a side adjacent to the housing and applies a preload to an outer wheel or an inner wheel of the bearing. The fuel-saving apparatus using such a variable preload may reduce a driving load acting on the driving shaft by a fixed preload acting by the bearing, thereby reducing the driving load of an engine and saving fuel.

摘要： A front bearing (tapered roller bearing) includes an inner ring, an outer ring, a plurality of tapered rollers, a cage, and a lubricating oil holding member. The lubricating oil holding member includes: a cylindrical portion having an axial length from a large diameter-side outer ring end surface to an end portion of the cage and capable of resisting a pressing force for press-fitting the outer ring; a fitting hook that is connected to one end of the cylindrical portion, that projects in the axial direction from an abutment surface which is in surface contact with the large diameter-side outer ring end surface, and that is fitted in an engagement groove portion provided in an outer peripheral surface of the outer ring; and a projection that projects radially inward from an inner peripheral surface of the cylindrical portion.

摘要： A ball bearing sleeve is used in a turbocharging device. The ball bearing sleeve has one or more ball bearings that are designed to control loads that are applied to the sleeve in the x, y and z-directions. The ball bearing sleeve is designed to replace the “thrust bearing” that is typically the “weak link” in a turbocharging device, as well as the journal bearings. The sleeve is designed to include a cylindrical portion that includes one or more grooves for directing the flow of oil around the sleeve for cooling. An oil duct having access holes directs the flow of oil into the ball bearings. Sleeve device may be retro-fitted into an existing turbocharger, which originally had journal and thrust bearings.

摘要： A fan includes a shaft, a first rolling bearing provided on one end side of the shaft in an axial direction of the shaft and having a first inner ring on an outer circumference side of the shaft and a first outer ring on an outer side in a radial direction of the first inner ring, a second rolling bearing provided on another end side of the shaft and having a second inner ring on the outer circumference side of the shaft and a second outer ring on the outer side in a radial direction of the second inner ring, a bearing housing accommodating the first and second rolling bearings, an elastic member between the first and second rolling bearings. At least one of the first and second rolling bearings is a loose-fit bearing. A resistance-applying part is interposed between the loose-fit bearing and the elastic member.

摘要： A planetary gear reducer has a planetary carrier supported by an input-side main bearing and an output-side main bearing. An angular contact ball bearing or a deep groove ball bearing which requires less installation space and is inexpensive is used for the input-side main bearing. A tapered roller bearing having a large capacity is used for the output-side main bearing. A compact, flat and inexpensive planetary gear reducer can be realized in comparison with a case in which the both main bearings are tapered roller bearings.
