A molded motor 100 includes a molded stator formed by providing a molding resin to a stator, a rotor inside the molded stator, a pair of bearings supporting a rotor shaft of the rotor, and an insulating bracket fitted in an inner circumferential part of an opening formed at an axial end of the molded stator to surround and support an outer ring of the bearing with a concave part formed at a center, and formed of an insulating resin.

This application is directed to an apparatus for providing electrical charge to a vehicle. The apparatus comprises a driven mass, a generator, a charger, a hardware controller, and a communication circuit. The driven mass rotates in response to a kinetic energy of the vehicle and is coupled to a shaft such that rotation of the driven mass causes the shaft to rotate. The driven mass exists in one of (1) an extended position and (2) a retracted position. The generator generates an electrical output based on a mechanical input coupled to the shaft such that rotation of the shaft causes the mechanical input to rotate. The charger is electrically coupled to the generator and: receives the electrical output, generates a charge output based on the electrical output, and conveys the charge output to the vehicle. The controller controls whether the driven mass is in the extended position or the retracted position in response to a signal received from the communication circuit.

A bearing assembly includes a roller bearing connected with a bearing support having a plate-shaped section. The bearing support has a receiving bore for an outer ring of the roller bearing, and the outer ring of the roller bearing is affixed to the bearing support with two affixing plates that are fixed to first and second end sides of the bearing support and that clamp the outer ring at two clamping surfaces. An axial spacing of the first and second end sides of the bearing support is smaller than an axial spacing of the clamping surfaces of the outer ring, and the two affixing plates have a different mechanical strength.

A housing for a bearing cavity in a gas turbine engine is disclosed. The housing comprise features that mitigate heat transfer from a heat source in the gas turbine engine to the nearby bearing cavity to prevent exposing the oil in the bearing cavity to excessively high temperatures. The housing comprises an annular flange that defines one or more barriers to heat transfer from the heat source to the bearing cavity.

Bearing assemblies and methods of forming the same are disclosed. The bearing assembly may include an outer bearing ring having a first outer diameter and defining an outer race and a radially outer surface. A radial extension may be coupled to the radially outer surface of the outer bearing ring to expand an outer diameter of the bearing assembly from the first outer diameter to a larger second outer diameter. The second outer diameter may be configured to correspond to a diameter of a housing cavity that is larger than the first diameter such that the bearing assembly can be coupled to the housing (e.g., press fit into the housing). The radial extension may be over-molded or press fit onto the outer bearing ring. The radial extension may be formed of a material less dense than the outer bearing ring, such as a polymer or elastomer.

A shaft bearing assembly including a housing, in which a bearing is arranged, is disclosed. The housing includes a first and second flange part. The first and second flange parts can be connected to each other, wherein the two flange parts jointly form a receptacle for the rolling-element bearing, wherein one of the flange parts has at least one securing interface and the other has at least one securing counter-interface, wherein the first and second flange parts can be connected to each other and/or fixed to each other in a positive-locking manner by the securing interface and the securing counter-interface that prevents the two flange parts from detaching from each other in an axial direction established by projecting the axis of rotation of the rolling-element bearing onto the housing. The first and second flange parts are hooked to each other by the securing interface and the securing counter-interface.

Load sharing stacked bearing structure including first bearing having a first inner race, first outer race and first set of roller elements housed between first inner race and first outer race and a second bearing having a second inner race, second outer race and second set of roller elements housed between second inner race and the second outer race. A housing surrounds the first and second bearings. First compliant element is provided with the first compliant element connected between the housing and the first outer race. The first compliant element, first outer race and housing define at a pressure chamber. The first outer race axially slidable relative to the second outer race such that an increase in pressure in pressure chamber causes a change in axial spacing between the outer races. This induces an additional axial load on the bearings which helps balance thrust load sharing.

Hobby servo blocks are provided. In certain circumstances, servo blocks may increase a servo's load-bearing capabilities by helping to isolate the lateral load from the servo spline and case. The extreme versatility of servo blocks allow users to create complex, extremely rigid, structures with ease using standard servos. The robust framework acts as a servo exoskeleton, greatly enhancing the mechanical loads the servo can withstand. Additionally, servo blocks may include a hub pattern that is repeated throughout the framework to allow endless attachment options.

A ball bearing and housing assembly includes a shaft having a stepped bore extending therethrough. The stepped bore is defined by a first bore segment having an inboard cylindrical interior surface that has a first bore diameter. The first bore segment extends from a shaft end and terminates at a shoulder. The shoulder is axially located between a first radial centerline of a plurality of balls and an inner axial end. The stepped bore is further defined by a second bore segment having an outboard cylindrical interior surface that has second bore diameter. The second bore segment extends axially from the inner axial end towards the shaft end and terminates at the shoulder. The second bore diameter is greater than the first bore diameter. A fastener is fitted through the first bore segment and threaded into a housing.
