Description

Gear drive
Technical field
A kind of the present invention relates to mechanical part, more particularly to gear drive.
Background technology
This gear drive is disclosed by 20 2,004 021 807U1 of DE.The geartrain configurations are passed into planetary gear Motivation structure and define the prime of large scale wind turbogenerator.The planetary gear mechanism include hollow wheel, two or One of multiple planetary gears and a sun gear, wherein described gear or multiple gears include multiple teeth, and the tooth has The superlinishing surface of surface roughness Ra=0.25 μm or less.Should be reduced by such superlinishing surface or Eliminate the metal abrasion on gear.On the one hand metal abrasion can cause the excessive wear of tooth and thus cause the failure of gear. On the other hand, this abrasive dust can be entered in bearing and there cause bearing damage.
The content of the invention
The task of the present invention is to provide a kind of gear drive, and the gear drive is in safety in operation and its fortune Improved in terms of row reliability.
The task is resolved by the following method, that is, arrange a kind of device, is constructed so as to the device and is arranged In gear drive housing so that the part dropped by transmission mechanism component and/or transmission mechanism housing is away from gear Intermeshing engagements.Arbitrary part and transmission occurs in the larger large-scale transmission mechanism for having power to be passed especially Mechanism unclamps, but the transmission mechanism does not have at once related meaning for the function of transmission mechanism.Thus, in routine It can be complete foot the corresponding transmission mechanism component that the part unclamps therewith to be substituted or is keeped in repair in maintenance span No more.But the part for dropping can its reach two gears intermeshing engagements in when cause teeth portion to damage.This possibility is led to Cross and be avoided by the device of the present invention.
Described in the improvement project of the present invention, device is capture and let-off gear(stand).The capture and let-off gear(stand) are so towards biography The part orientation for having risk of rupture of motivation structure, so as to capture the part and make it away from nibbling for gear during rupture Close occlusion.
To capture in other designs of the present invention and let-off gear(stand) is integrated into transmission mechanism housing and/or gear holds In holder.Do not result in or only cause little extra manufacture to spend or be driven by being integrated in the part of presence The assembling of mechanism spends.Here, capture and let-off gear(stand) are configured to two overlaps in other designs of the present invention Projection.Here, the present invention improvement project in again projection is arranged on the bearing of hollow wheel and transmission mechanism housing on. This design only needs to the design on the Bullet structure of corresponding projection, and the wherein projection by being constructed so as to will not at least be drawn Play extra processing and assembly costs.
Described in the improvement project of the present invention, transmission mechanism housing and/or bearing are foundry goods.In the casting can be with letter Corresponding projection is shaped singly, method is that the corresponding mold of modification is used for constructing this projection.
The present invention improvement project in be constructed so as to the capture and let-off gear(stand) so that the part along capture and Simply can find on fixed position and for example when checking or safeguard transmission mechanism.
The present invention improvement project in, the part be screw, bolt, nut, a part for screw, one of bolt Point, a part for nut or other parts.Especially for example can be due to mistake in the gear with one or more threaded connections The threaded connection tightened by mistake and cause the screw or nut fracture of this threaded connection, wherein this fracture will not to gear and Thus the function of transmission mechanism has a direct impact.
In the improvement project of the present invention, design flow energy installation (Stroemungsenergieanlage), especially wind Energy equipment or ocean energy equipment and/or power train, which carries the transmission mechanism as any one of the claims. Finally, it is to be noted, that present subject matter avoids teeth portion from damaging with being designed for protective, its for example can in into wind energy plant when Cause larger Consequential Loss.Thus, can also for example propose detection means is arranged in capture and let-off gear(stand) or is set Put on the oil sump of the part dropped in detection.The detection means can also be connected with shutoff device, and the shutoff device is due to institute Detection the part for dropping and trigger closing wind energy plant, will not occur on wind power installation other continuity Consequential Losses.
Description of the drawings
Other favourable designs of the present invention are obtained from description of the drawings, describe this in the description of the drawings in detail The bright embodiment being shown in the drawings.
Fig. 1 is the side view of the wind power installation with the gear drive by present invention design,
Fig. 2 is the sectional view of the intercepting part of a level of the planetary gear mechanism for wind energy plant, and
Fig. 2 a are the intercepting magnified partial views of Fig. 2.
Specific embodiment
Embodiments of the invention are described in further detail below in conjunction with accompanying drawing.
Fig. 1 shows the side view of the wind power installation 1 with its primary clustering.Wind power installation 1 has pylon 2, in the tower The gondola 3 of the chassis form that can be rotationally derived supporting around vertical axis is arranged on frame.In the gondola 3 un-rotatably Fixed conveyor mechanism 4, the wherein transmission mechanism 4 have drive shaft 5 and output shaft 6.The drive shaft 5 of transmission mechanism 4 with have it is many The wheel hub 7 of the rotor of individual rotor blade 8 connects.The output shaft 6 is revolved with there is the driving means of 9 forms in generator to be driven Turn connection.It is so designed that the transmission mechanism 4 so that the slow rotary motion of drive shaft 5 is converted into the fast of output shaft 6 by which The rotary motion of speed.Electric energy is produced by means of the wind power installation 1, method is that the rotor being placed in by wind-force among rotary motion will Rotary motion is imported in transmission mechanism 4 by drive shaft 5.The transmission mechanism 4 converts rotational motion to faster rotary motion And transmit quick rotary motion for electric current being produced on generator 9 finally by output shaft 6.
Fig. 2 schematically shows the intercepting portion of the transmission mechanism 4 for being configured to wind energy plant as differential drive mechanism Point, the transmission mechanism has.Shown Planetary gear mechanism is related to a level of transmission mechanism 4, and the left side of wherein transmission mechanism 4 is connected with rotor-side and right side It is connected with the generator side of transmission mechanism 4.
