Description
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.
