SYSTEM FOR MONITORING A ROLLING BEARING AND ASSOCIATED METHOD
A method for monitoring a rolling bearing that has a sensorized rolling element includes sampling acceleration signals and load signals from the sensorized rolling element to produce acceleration values and load values each associated with a time instant, determining a rotation speed of the rotatable ring, determining a phase function of the sensorized rolling element from the acceleration values and the rotation speed of the rotatable ring, processing the load values to determine a magnitude of a resulting signal representative of a frequency content of an envelope of the load values over time, and detecting a damage of the rolling bearing and a location of the damage on the rolling bearing from the magnitude of the resulting signal and the phase function.
An assembly includes a fastening screw having an end surface and a substantially cylindrical side surface extending axially away from the end surface and a protective cap covering the free end. The cap has a first end opening from which the fastening screw extends, a second end overlying the end surface of the fastening screw, a side wall surrounding a portion of the cylindrical side surface, an inner surface defining a cap interior, and an outer surface. A cap screw extends through an opening in the second end of the cap and into a threaded opening in the end surface of the fastening screw to secure the protective cap to the fastening screw.
A method of designing a ball bearing includes providing a value of a shaft outside diameter and a load. An inside diameter of a bearing inner ring is determined based on the value of the shaft outside diameter. A ball size having a specific ball diameter is selected and a number of the balls of the selected standard ball size required to support the load is determined. A pitch diameter of a pitch circle of the ball bearing is determined based on the determined number of balls of the selected ball size. A suitability factor is calculated for the particular value of the pitch diameter and the particular pitch diameter is validated as suitable when the suitability factor is between calculated upper and lower limits.

Bearing unit (30) has a central axis of rotation (X) and a retaining cage (40) for a plurality of rolling bodies (34) interposed between a radially outer ring (31) and a radially inner ring (33). The retaining cage (40) has a base rib (41), a plurality of tenons (42) that are spaced apart circumferentially and rigidly connected to the rib (41), and a plurality of pockets (43). Each pocket (43) is delimited by the rib (41) and by a respective pair of adjacent tenons (42). Each pocket (43) is defined by a respective radially outer spherical surface (44) and by at least one respective radially inner cylindrical surface (45) radially adjacent to the spherical surface (44).
A hub-bearing assembly having an axis of rotation includes a stationary radially outer ring and a flanged hub radially inside the radially outer ring and rotary about the axis and about the radially outer ring. The flanged hub has a toothed profile and an axially inner tubular portion. A radially inner ring is mounted in axial abutment on the flanged hub. A toothed sleeve is mounted axially close to the radially inner ring and angularly coupled to the toothed profile of the flanged hub. The flanged hub has a profile gradually transitioning between a radially outer surface of the toothed profile and a radially outer cylindrical surface of the tubular portion of the flanged hub.
A bearing assembly is for supporting a shaft in a housing, preferably a rotor shaft of a centrifugal compressor. The bearing assembly includes at least a first bearing pair including a first rolling bearing and a second rolling bearing arranged back to back, each one of the first and second rolling bearings including an inner ring attached to the shaft, an outer ring and a plurality of rolling elements disposed between the inner ring and the outer ring. A radial gap is provided between the outer ring of the first rolling bearing and the housing and the outer ring of the second rolling bearing is in contact with the housing. Preferably, a fixing element restricts axial movement of the outer ring of the first rolling bearing with respect to the housing.

CAGE FOR ROLLING ELEMENTS OF HIGH-SPEED BEARING AND HIGH-SPEED BEARING
A cage for rolling elements of a high speed bearing. The cage includes a cage body made of a polymer material. The cage body includes a lubrication enhancer and/or an elastic modulus enhancer added to the polymer material during the manufacturing process. The lubrication enhancer makes the cage have a low friction coefficient, low heat generation and good wear resistance, and the cage has better stability when the bearing is under high temperature or high speed. The elastic modulus enhancer makes the cage have an excellent high elastic modulus, and the deformation of the cage is significantly reduced under the condition of high-speed operation of the bearing. These effects can be obtained by adding both the lubrication enhancer and the elastic modulus enhancer at the same time, which makes the cage more suitable for high-speed bearings.
A system for handling separation layers in a production process includes at least one separation layer and a handling apparatus. The handling apparatus is preferably a vacuum gripper and is provided to move the separation layer. The separation layer has at least one slot which facilitates bending of the separation layer during lifting of the layer by the handling apparatus, such bending releasing the separation layer being lifted from another separation layer located in a stack of separation layers beneath the lifted layer.

DEVICE FOR PREDICTING THE EVOLUTION OF A DEFECT OF A BEARING, ASSOCIATED SYSTEM AND METHOD
A method for predicting the evolution of a defect of a bearing includes identifying a defect of the bearing and extracting geometrical parameters of the identified defect by a trained deep learning algorithm from a picture of the bearing and further includes predicting an evolution of the identified defect of the bearing from a type of the identified defect and the extracted geometrical parameters of the identified defect, from operating parameters of the bearing and from a model of the bearing. Also a device for performing the method.
