A buffer member extends from the first seal element toward the second seal element and has first and second radially spaced annular ribs that extend toward the second seal element. | 2022-06-23 |
20220196075 | VAPOR COMPRESSION SYSTEM AND METHOD OF EXTENDING SERVICE LIFE OF SAME - A vapor compression system including a motor having a housing and a shaft having an axis, the shaft urgable into rotational movement by the motor for powering a system component. A primary bearing and a secondary bearing are positioned in the housing for rotatably supporting the shaft, the primary bearing rotatably supporting the shaft during normal system operation. A first bearing stop and a second bearing stop are positioned on opposite sides of the secondary bearing for transmitting axial forces generated along the shaft for reaction by the motor housing during abnormal system operation. At least a portion of corresponding surfaces of each of the first bearing stop and the second bearing stop facing the secondary bearing have a protective overlying layer of material applied thereto. | 2022-06-23 |
20220196076 | METHOD FOR MANUFACTURING A TARGET HOLDER FOR SENSOR BEARING UNIT - The method concerns the manufacturing of a target holder for sensor bearing unit, having a preliminary step of manufacturing a metal sheet, and a step of manufacturing the target holder. The manufacturing step of the target holder includes a forming operation of the target holder from the manufactured metal sheet providing the target holder with at least an axial fixing portion intended to be secured to a ring of the sensor bearing unit, and with a radial portion extending at least radially with respect to the axial fixing portion, a curved linking portion being formed between the axial fixing portion and the radial portion. At least one of the manufacturing steps comprises a surface roughening operation providing a surface roughness value ranging between 0.05 μm and 0.95 μm. | 2022-06-23 |
20220196077 | ASSEMBLY FOR CONNECTING AN ADAPTER SHAFT TO A SHAFT IN A FORCE-FITTING MANNER USING A CLAMPING RING - In an assembly for connecting an adapter shaft to a shaft in a force-fitting manner using a clamping ring, the clamping ring is mounted on the adapter shaft, the shaft is inserted into the adapter shaft, the clamping ring has a first radially uninterrupted threaded bore into which a first screw part is screwed, in particular a first threaded pin, which exerts pressure on the adapter shaft, the clamping ring has a second radially uninterrupted threaded bore into which a second screw part is screwed, in particular a second threaded pin, and the second screw part projects at least partially into a recess of the adapter shaft and in particular exerts pressure on the adapter shaft. | 2022-06-23 |
20220196078 | POWER TRANSMISSION SHAFT AND PROPELLER SHAFT FOR VEHICLE - A power transmission shaft has a shaft member having, on an outer peripheral surface thereof, a male spline; a cylindrical member having, on an inner peripheral surface thereof, a female spline; and a seal member provided in a pressed state between an outer peripheral seal surface formed on the outer peripheral surface of the shaft member and an inner peripheral seal surface formed on the inner peripheral surface of the cylindrical member. The cylindrical member is spline-engaged with the shaft member by one end side of the shaft member being inserted into the cylindrical member from an other end side of the cylindrical member. Axial direction shock is absorbed by sliding of the splines. The outer peripheral seal surface is positioned at the other end side with respect to the male spline, and the inner peripheral seal surface is positioned at the other side with respect to the female spline. | 2022-06-23 |
