A wheel driving apparatus is provided. The wheel driving apparatus includes a cylindrical inner housing supported by a vehicle body via a suspension, a wheel supported by the cylindrical inner housing so that the wheel is rotatable relative to the cylindrical inner housing, a motor having a stator attached to the cylindrical inner housing and a rotor attached to the wheel. The wheel includes a main body portion and an outside portion positioned on an outer side of the vehicle body, and the rotor is attached to the main body portion.

A mechanical seal of an “outside type” for sealing a sealed fluid that may leak from an inside periphery of a sliding face towards an outside periphery is provided. The seal includes a rotating-side sealing element and a stationary-side sealing element disposed so as to be situated externally with respect to a stuffing box. The stationary-side sealing element, which accommodates a spring, is installed on a seal cover that is secured to the housing. The rotating-side sealing element is installed on a collar that is installed directly on the rotating shaft. The rotating side, which comprises the rotating-side sealing element and the collar, is positioned such that rotation takes place in the atmosphere on a machine-exterior side. A balance ratio A2 / A1 is 1 or less, A1 being an axial-direction projection area of the sliding face of the stationary-side sealing element and A2 being an axial-direction projection area that is subjected to a seal fluid pressure acting as a motive force in the axial direction relative to the stationary-side sealing element. An annular cooling jacket is disposed between an inside periphery of the housing and an outside periphery of the rotating shaft.

The invention relates to an electric drive for a vehicle. A housing (1) that is stationary in relation to the vehicle frame is provided. A motor housing (5) having a stator (4) and a rotor (7) being provided in said motor housing (5) are rotationally mounted in said housing. The motor housing and the rotor perform opposite rotational movements. A drive train (2) is connected to the motor housing and the rotational movement of the motor housing is carried out by means of a transmission device with the same drive and output direction of rotation. The remaining drive train is connected to the rotor and the rotational movement of the rotor is carried out by means of a transmission device with opposite drive and output direction of rotation. The transmission devices are planetary gears. The rotor engages with the planet wheels (13 or 16) of the allocated planetary gear by means of a spur pinion (10) that is arranged on the shaft or the motor housing engages with the planet wheels of the allocated planetary gear by means of a spur pinion that is connected to the motor housing and is arranged on the axis of the motor housing. A web (14 or 17) is provided. Said web is connected to the axles of the planet wheels of each planetary gear and drives the wheel shaft assigned thereto.

A gravity type tiltable metal mold casting machine, comprising: a pair of opposing upright supporting frames (2, 2); a pair of opposing main rotating shafts (3, 3) rotatably mounted on the upright supporting frames (2, 2); a main frame (4) suspended from and between the main rotating shafts (3, 3); an electric motor (19) attached to one of the main rotating shafts (3, 3) for reversibly rotating it and hence the frame (4); a drag die plate (6) vertically moved by mold-fastening cylinders (5, 5) mounted on a lower part of the main frame (4); a metal drag (10) secured to the drag die plate (6), the metal drag having a drag pushing-out mechanism (23) for pushing an as-cast product out of the metal drag; a pair of opposing horizontal cope tilting shafts (13, 13) secured to an upper end of the main frame at locations rearward of the main rotating shafts (3, 3); a cope-attaching frame (14) rotatably mounted at one end on the cope tilting shafts (13, 13); a cope die plate (16) secured to a lower surface of the cope-attaching frame (14); a metal cope (17) secured to the cope die plate (16), the metal cope having a cope pushing-out mechanism (26) for pushing an as-cast product out of the metal cope, a ladle (21) rotatably mounted about a horizontal axis of rotation, the horizontal axis of rotation being located rearward of the assembly of the metal cope and drag; and an electric motor (9) for reversibly rotating the ladle (21) about the horizontal axis of rotation, wherein the center of the assembly of the metal cope and drag is substantially on the axis of rotation of the main rotating shafts.

In a bearing assembly of a centrifugal revolving drum (1) around a spin axis (6), the revolving drum (1) is fixed by rotation through a drum hub (2) and a hanger bracket (21) of the revolving drum (1) and connected with a drive shaft (3). The drive shaft is connected with a drive set (12) and extends along the spin axis (6) in the bearing block (4, 7, 8, 9, 20, 24). The revolving drum (1) is supported on the bearing block (4, 7, 8, 9, 20, 24), thereby basically separating supporting force generated by power from the drive shaft (3).
