Systems and methods are provided for a gearcase of a motor and wheel set assembly configured to enclose a gear set, including a first case element, a second case element configured to mate with the first case element to contain lubricating oil for at least the gear set and a pinion, and a rubberized seal. In one example, a system may include permanent rubberized seals sealing an opening configured to receive the pinion, an interface between the first case element and the second case element and a bearing cap.

The present invention relates to the field of automated transportation systems. Particularly, it relates to a transportation system comprising guide-ways or tracks, vehicle units [100, 100a] with wheel-axle assembly for switching of vehicles from primary [20] to secondary track [22] on changing trajectory to maintain same vertical plane and the method. It comprises of central controller [101], vehicle chassis with main wheels [2W], guide wheels [4iw, 4ow], guide blocks [05, 06], actuator [09]. The chassis [30] has set of contractible axles fixed to wheels [2W] to enables movement from primary [20] to secondary track [22] by withdrawing the wheels [2W] from expanded position [C] to contracted position [C] or vice-versa. The forces required to compress the spring loaded axle axis is derived from inner guide wheels rolling over the edge flange [26] when swung using single linear motor actuator [09] and related electronic controls.

A planetary gear device includes a bearing inner cylinder including an internal gear on the inner circumferential side, a bearing fitted on the outer circumference of the bearing inner cylinder, an output shaft outer cylinder fitted on the outer circumference of the bearing, and an output shaft end plate that fixedly supports the planetary carrier and transmits a rotation thereof to the output shaft outer cylinder. A wheel is fitted onto the outer circumference of the output shaft outer cylinder so as to prevent relative rotation. The bearing inner cylinder is fixed to a support frame. A drive motor is fixed coaxially with the planetary gear device on the side of the support frame opposite to the bearing inner cylinder, and a rotation shaft is coupled to the sun gear.

A bearing assembly for a traction motor of a railway vehicle includes at least one rolling-element bearing having an inner ring and an outer ring. At least one row of rolling elements is disposed between the inner ring and the outer ring. A sealing assembly is disposed in at least one of the axial end portions of the rolling-element bearing. The sealing assembly includes a first sealing region disposed adjacent to the bearing rings, and a second sealing region spaced farther from the bearing rings than the first seal region. The first sealing region includes a lip seal, and the second sealing region includes a labyrinth seal. The internal volume surrounding the rolling elements located between the bearing rings is in fluid communication with the atmosphere.

A wheel-axle generator equipped with a rotor configured to rotate with rotation of a wheel and a stator arranged around the rotor. The rotor is fixed to a concave portion that opens toward a vehicle outside of a tire wheel of a wheel. An arm member that has one end attached to a wheel-axle housing or a steering knuckle), that extends so as to stride over a wheel, and that, on a side of an outer surface of the wheel, further extends parallel to the outer surface of the wheel up to a central portion of the wheel. The stator is annularly arranged so as to surround the rotor and is provided on the other end side of the arm member. This arrangement provides space for accommodating a generator without shortening a wheel axle etc. and attaching the generator easily.
