摘要:
The invention relates to a hydrodynamic machine, in particular a hydrodynamic coupling, having a bladed primary wheel (1) and a bladed secondary wheel (2) which is stationary or revolves about the axis of rotation, said wheels forming a working chamber with one another, in order to transmit torque hydrodynamically, wherein the primary wheel and/or the secondary wheel is rotatably mounted by means of at least one plain bearing (7, 8). In addition the hydrodynamic machine has a lubricant supply system (33) for the at least one plain bearing, comprising a lubricant source (28) connected by means of at least one lubricant supply line to the plain bearing, and has a lubricant outlet (34) which is connected by means of a lubricant discharge line (31) to the at least one plain bearing, such that in the lubricant supply line and/or the lubricant discharge line a lubricant reservoir (15) is provided which, for formation of a lubricant circuit between the lubricant reservoir and the at least one plain bearing, in the event of a failure of the lubricant supply from the lubricant source, is connected to the at least one plain bearing by means of at least one lubricant feed conduit (16) and at least one lubricant return conduit (17).

A vibration damping device which can improve a vibration damping performance of a damper having a chamber holding a rolling member. The vibration damping device is applied to a power transmission unit having an input side rotary member 24, 25 that transmits a power to an elastic member 26 and an output rotary member 19 that is rotated by the power transmitted from the elastic member. In order to damp vibrations of the output rotary member, the vibration damping device is comprised of a holding chamber rotated integrally with the input side rotary member 24, 25, and a rolling member 28 held in the holding chamber in a manner to rotate in a same direction as the output side rotary member 19 while being allowed to rotate relatively therewith.

Providing a vehicle power transmission device including a hydraulic power transmission device and enabling a shorter entire axial length. A vehicle power transmission device 12 includes a torque converter 18 and an automatic transmission 20 in a power transmission path between an engine 14 and drive wheels 16, the torque converter 18 including a rear cover 38 disposed with a plurality of pump blades 40, a turbine 42 disposed with a plurality of turbine blades 44 receiving a fluid flow from the pump blades 40, and a stator 46 disposed with a stator blade 45 disposed between the pump blades 40 and the turbine blades 44, the automatic transmission 20 transmitting power input to an input shaft 48 from the torque converter 18 to a subsequent stage. A release-side flow passage 132 acting as a circulation outward passage allowing fluid to flow toward the inside of the torque converter 18 at the time of a circulation of the fluid in the torque converter 18 is made up of a cylindrical gap 132a between the input shaft 48 and a stator shaft 62.

A hydraulic drive assembly for a large pre-existing pressurized digester vessel (10) and a method of installation of the hydraulic drive assembly have been conceived. Such a device includes a stub shaft (32) which has a lower end (34) and an upper end (36). The lower end (34) engages with a hydraulic drive (38) and the upper end (36) is coupled to a drive shaft (20). The coupling (30) further includes a top coupling (40) and a bottom coupling (42). The top coupling (40) is coupled to the drive shaft (20), and the bottom coupling (42) is coupled to the stub shaft (32). A drive support bracket (46) is attached to the hydraulic drive (38) and then attached to the drive support bracket (46) by at least one sole plate (26) that is fixed to a foundation (28). The hydraulic drive assembly installation method is utilized when removing an electric motor and mechanical transmission device and replacing it with a hydraulic drive assembly.
