摘要： Disclosed is a yaw driving device for a wind turbine, wherein when the pressure of a gas within a case is increased, the pressure of the gas within the case is automatically reduced without a manual operation, so that the breakage of a seal element is prevented, the leakage of a lubricant oil within the case and the entry of a foreign substance into the case are suppressed, and the increase of the size of a mechanism is suppressed. A relief valve (13) which is projected upwardly is provided on the upper end of a case (12) to which an electric motor (100) is attached. The relief valve (13) is comprised of a communication path (34) and a valve body (32) which opens an opening (34b) facing toward the outside of the communication path (34) in accordance with the increase of the pressure of the gas within the case (12) and closes the same in accordance with the decrease of the pressure. A shoulder portion (23) which is disposed above an oil level (25) of the lubricant oil and which is inwardly stepped, and a wall portion (22) which extends in upward and downward directions are formed on the upper end of the case (12). The opening (34a) of the communication path (34), which faces toward the inside of the case (12), is open at the inside of the shoulder portion (23) and at the outside of the wall portion (22) in the case (12).

摘要： A gear mechanism for driving screws of a twin-screw extruder comprising two parallel output shafts (1, 2) of different lengths, the longer output shaft (1) of which carries a drive gear wheel (3). The short output shaft (2) is connected by way of a pinion (6) in a rotationally fixed manner to three gear wheels (10, 11, 12), which can be driven by the longer output shaft (1) by way of a hollow wheel (20) provided with internal toothing (19). Seated on the longer output shaft (1) is a pinion (5) that is in direct engagement with the pinion (6) of the shorter output shaft (2). The hollow wheel (20) is also provided with external toothing (21), which is in engagement with gear wheels (22, 23) of two intermediate shafts (24, 25), which mesh with the drive gear wheel (3) by way of further gear wheels (26, 27).

摘要： Disclosed is a planetary gear system comprising a driven sun wheel (4), an internal gear (16), a group of first planetary gears (12), and a group of second planetary gears which are embodied as stepped planetary gears (8) that are provided with small step wheels (10) and large step wheels. The single gearing area of each of the first planetary gears (12) simultaneously engages with the internal gear (16) and a small step wheel (10) while the large step wheels (6) of the stepped planetary gears (8) mesh with the sun wheel (4). The first planetary gears (12) and the stepped planetary gears (8) are mounted within a common planet carrier (14). The number of stepped planetary gears (8) corresponds to half the number of the first planetary gears (12). The small step wheels (10) of the stepped planetary gears (8) simultaneously engage with a pair of adjoining first planetary gears (12). The internal gear (16) and the first planetary gears (12) are embodied in a conical manner while means (38, 40) are provided for adjusting the axial position of the first planetary gears (12) such that the tooth clearance is adjustable.

摘要： There is provided a planetary reduction gear 10 between a gas turbine 1 and a generator 5. The planetary reduction gear includes elastic deformation means 12 on an output side, and for the elastic deformation means, a strain energy within an elastic limit is set to be larger than a fluctuation torque energy of the generator of a momentary voltage drop time. The elastic deformation means 12 includes an elastic member which elastically connects an output shaft 10a of the planetary reduction gear to an outer ring 10b. Thereby, when an excessive torque is generated in the generator by a momentary voltage drop, service interruption, and the like for a short time, it is possible to maintain the operation of a power generation facility, and secure a power supply of an important load, and an installation length is shortened and the facility can be downsized.
