Definitions

  • the invention relates to a housing for a transmission, in particular an integral transmission for a gear turbomachine, having the features of the preamble of claim 1.
  • Gearboxes for turbomachinery interact with compressors, expanders, steam turbines, motors and generators.
  • EP 1 691 081 B1 a multi-stage geared turbomachine with an integrated transmission and with input and / or output units is shown, which can be provided as input and output units compressors, steam turbines, gas turbines, motors, generators and expander.
  • Such transmissions are characterized in that on the one hand the arrangement of these units is provided in the same horizontal plane and on the other hand by the presence of a drive wheel with a plurality of output sprockets, whereby the integration of a variety of possibilities brings with it.
  • the drive and thus a power transmission takes place from a drive wheel to wheels that show different radii, but preferably have parallel aligned waves.
  • gears may be provided.
  • the gear is housed in a cast housing, which is preferably divided in the storage plane of the waves.
  • the cast housing on walls, which include a cavity in which the wheels are freely rotatable.
  • the wheels are coupled with shafts which are mounted in bearing elements, wherein the bearing elements are each provided in the region of the wall of the cast housing.
  • the bearing elements may be formed in such cast casings oval, so that they can still be machined after production of the cast housing to provide bearing elements for the respective position of the waves.
  • this has the consequence that on the one hand in these areas in the production of a cast accumulation, which in turn implies that there is a risk of voids.
  • voids one calls a cavity formed during the solidification of cast parts.
  • cavities lead to structural weaknesses of the housing, which lead to a breakage of such bearings, especially in the area of the bearings in which high forces act. Voids can also lead to leaks.
  • the object of the invention is to develop transmission housing of the above type such that it can be used for different shaft spacings of the wheels arranged in the housings.
  • the basic idea of the invention is to provide a base housing preferably made of cast material, wherein the base housing may be formed in one or more parts.
  • a plurality of bearings is provided at the base housing. These bearings are not suitable for receiving the shafts for the transmission. These bearings are large recesses or recesses within the basic housing. The recesses are many times larger than the diameter of the respective shafts, which are to be accommodated with a bearing. Thus, a bearing indicates only the rough position of the respective waves.
  • the bearings are designed such that a bearing element or a plurality of bearing elements can be accommodated, which are firmly connected to the one with the basic housing and provide the other support location for the waves.
  • This bearing element is therefore a separate component which can be introduced into the bearing.
  • the bearing element and the base housing may be made of the same material. It is also conceivable if the bearing element made of a different material than it has the basic housing exists. The bearing element can therefore also be specially designed. This means that other material properties are present in the area of the attachment to the base housing than in the area of the receptacle for the shafts.
  • the receiving areas for the waves can already be provided with lubricant.
  • the fixed connection between the base housing and bearing element can be achieved for example by screws or equivalent fastening means.
  • the exact positions of the receiving bearing with respect to the base housing are dependent on the design of the bearing element. This makes it possible, depending on the corresponding selection of the bearing element to realize different positions of the waves with one and the same basic housing.
  • the bearing elements are formed in a preferred embodiment as a disc or flange.
  • the bearing element has a fastening region, which cooperates with the base housing of the transmission housing and is attached via fastening means on this either releasably or permanently.
  • the bearing element has a storage area. This storage area is designed such that it at least indirectly (either via bearing means, such as ball bearings, or directly) receives the shaft rotatable about its own axis.
  • bearing means such as ball bearings, or directly
  • the bearing element is only one half, namely, when the base housing is also formed at least in two parts. Only by joining the individual parts of the basic housing then forms the bearing element and a complete functional element.
  • the gear housing is divided into at least two housing parts on an interface plane, a first half of a single bearing and consequently a bearing element in a first housing part and the other half of the bearing and a further bearing element in the second housing part are arranged.
  • the individual bearing element is then preferably a semicircular segment in plan view, wherein a flat side is formed on the end face, which comprises a bearing, ie either forms or receives.
  • the gear housing has circular recesses for receiving the bearing elements. The recesses are made on the gear housing and the bearing elements with the same Einpallons preparer and the bearing elements connected to the transmission housing. In the assembled Condition can then be made the bearing lane for training or recording a camp according to the requirements of the application.
  • the bearing element can also be designed such that its attachment region can be fitted in a flange-like or groove-like region.
  • the area for the receiving warehouse is preferably made wider, in particular to provide the support a wide areal edition.
  • Fig. 1 is a perspective view of a part of a transmission housing with
  • Fig. 2 is a perspective view of the transmission housing without
  • Fig. 3 is a perspective view of a bearing element.
  • the base housing 2 of the transmission case 1 of a transmission in particular Integralgetriebes with corresponding bearing elements 3 is shown.
  • the basic housing 2 one half of which is shown in the drawing, has housing walls 4, which enclose a cavity 5.
  • the cavity 5 serves to accommodate the different wheels for the transmission.
  • bearing points 7 are provided in the basic housing. These bearings 7 are designed round in cross-section, such that one half of the bearing point in the first part of the base housing 2 and another part is provided in the further part of the base housing 2, wherein the further part of the base housing is not shown in the drawings.
  • the bearings 7 correspond to the approximate positions occupied by the respective shafts.
  • the bearings 7 are embossed by the bearing elements 3.
  • Such a bearing element 3 for one half of the basic housing is shown alone in FIG. It consists of a semicircular segment 9, which preferably provides a semicircular connection area 10 for mounting on the transmission housing 1 by means of fastening elements 1 1.
  • the fasteners 1 1 are in the present example screws that penetrate holes 12 at a mounting portion 13, wherein the head of the screw rests on the connection portion 10 and the segment 9 presses against the base housing 2.
  • the connection region has bearing surfaces 14 which are in operative connection with further bearing surfaces 15 on the transmission housing 1. The width or the half diameter of the connection region 10 is greater than that of the actual segment 9.

Abstract

L'invention concerne un boîtier destiné à une transmission, à savoir une transmission intégrale. Le boîtier de transmission comporte un agencement d'une pluralité de roues qui sont fonctionnellement reliées entre elles. Les roues sont accouplées à des arbres rotatifs qui sont logés dans des points d'appui. Selon l'invention, les points d'appui (7) sont pourvus d'éléments d'appui (3). L'élément de palier (3) est un composant séparé indépendant du boîtier de transmission (1). L'élément de palier (3) comporte des éléments de raccordement (10) destinés à être fixés au boîtier de transmission (1) et au moins un palier (16) destiné à recevoir un arbre (17) d'une roue.
