Description

Technical Field

[0001] The present invention relates to a method for manufacturing a first transmission housing from a first housing blank and a second transmission housing from a second housing blank, as well as a series of transmission devices having a first transmission device and a second transmission device. Background Technology

[0002] Transmission device housings with housing guide sections are known in the prior art. To save cost and weight, the housing wall thickness is only implemented to the thickness necessary for strength reasons. A reinforcing section is required in the area of ​​the housing guide section. The positioning of the housing guide section is predetermined by the reinforcing section.

[0003] When the transmission housing has more reinforcing parts than the housing guide portion, it becomes possible to flexibly position the housing guide portion. Then, multiple reinforcing parts are selected for positioning the housing guide portion. However, this increases manufacturing costs due to unused reinforcing parts. Furthermore, the positioning of the housing guide portion still depends on the positioning of the reinforcing parts. It is impossible to install the housing guide portion in an intermediate position. Summary of the Invention

[0004] The objective of this invention is to improve the housing of a transmission device having a housing through-hole. This objective is achieved by the method according to the invention for manufacturing a first transmission device housing from a first housing blank and a second transmission device housing from a second housing blank, as well as a series of transmission devices having a first transmission device and a second transmission device. Preferred improvements are described below and Figure 1 The examples shown are derived from this.

[0005] According to the present invention, the transmission housing has at least one raised portion for introducing one or more housing insertion portions. The raised portion is a thickened portion. The raised portion is characterized in that it is raised relative to one or more surrounding regions of the transmission housing. Here, the surrounding regions are directly adjacent to the raised portion. The surface of the raised portion is raised relative to the surface of the surrounding regions. Therefore, the surface of the raised portion extends further into the surrounding space than the surface of the surrounding regions.

[0006] A through-hole is a through opening in the wall of a transmission housing. A through-hole has exactly two openings. The characteristic of a through-hole is that it connects the internal space of the transmission housing to the surrounding environment. Therefore, the through-hole leads into the internal space of the transmission housing and into the surrounding environment. For example, a through-hole can be designed as a through-hole.

[0007] According to the invention, one or more housing through-holes of the transmission housing are inserted into the raised portion. This means that each raised portion has an opening for the housing through-hole.

[0008] The raised portion makes it possible to introduce housing guide sections in different positions and / or different housing guide sections. This allows the housing blank to be flexibly used for different applications with different housing guide sections without requiring new design work.

[0009] One or more housing through-holes preferably each have one or more fixing mechanisms. Preferably, the fixing mechanism is a thread, especially an internal thread introduced into the housing through-hole.

[0010] The fixing mechanism is used, for example, to fix oil lines, sensors, sealing plugs, or viewing glass. The oil lines are preferably fixed to both sides of the housing through-hole. The oil lines are then connected to each other through the housing through-hole in an oil-conducting manner. The housing through-hole, sealed with a plug, is used, for example, as an oil filling or draining opening. The oil level and condition present in the transmission housing can be inspected through the viewing glass.

[0011] The raised portion is preferably rotationally symmetrical. In a preferred improvement, the raised portion has a toroidal shape. The toroidal shape is a body of revolution whose axis of rotation extends through a hole in the body without intersecting the body. In the toroidal raised portion, exactly two of the aforementioned regions surrounding the raised portion are present.

[0012] In a further preferred embodiment, the transmission housing has an opening for an input or output shaft. The input shaft extends through the opening and is preferably sealed relative to the opening by means of one or more seals. The raised portion and the opening are arranged coaxially with each other according to the improved embodiment. This means that the raised portion and the opening are coaxial. Therefore, they have a common central axis or axis of symmetry.

[0013] The transmission housing preferably further comprises a gear ring and a connecting section. The gear ring is, for example, a planetary gear ring. The shaft that is anti-rotatably connected to the planetary carrier preferably forms the aforementioned input or output shaft.

[0014] The connecting section connects the gear ring to the opening. Specifically, the connecting section itself may have an opening. Furthermore, the gear ring and the connecting section can engage with each other or be connected as a single piece. According to an improvement, the connecting section has a raised portion.

[0015] In a further preferred embodiment, the raised portion has at least one flat surface. This flat surface has a generally annular shape. One or more housing through-holes preferably pass into this flat surface. Preferably, the flat surface serves as a sealing surface. The flat surface also simplifies the introduction of one or more housing through-holes.

[0016] The raised portion is preferably implemented as a single piece. In particular, according to the improved embodiment, the interface between different shell parts does not extend through the raised portion.

[0017] The raised portion preferably further comprises at least one of the aforementioned shell-through portions.

[0018] The method according to the invention is used to manufacture a first transmission housing and a second transmission housing. The first transmission housing and the second transmission housing are transmission housings according to the invention or preferred improvements thereof.

[0019] The first transmission device housing is made from a first housing blank. Correspondingly, the second transmission device housing is made from a second housing blank. A housing blank refers to a semi-finished product, which is used to manufacture either the first or second transmission device housing.

[0020] According to the present invention, the first shell blank and the second shell blank are structurally identical. This is the case if the shell blanks are consistent in their physical parameters (particularly in terms of their material and geometric properties) within the range of manufacturing tolerances.

[0021] The first housing blank and the second housing blank each have at least one raised portion. Different housing guide portions are introduced into the raised portions of the first housing blank and the raised portions of the second housing blank. Specifically, one or more housing guide portions are introduced into the raised portions of the first housing blank, while the raised portions of the second housing blank remain without housing guide portions, or at least one housing guide portion introduced into the raised portion of the first housing blank is different from all the housing guide portions introduced into the raised portion of the second housing blank.

[0022] If the first housing guide portion introduced into the protrusion of the first housing blank and the second housing guide portion introduced into the protrusion of the second housing blank differ in their geometric design and / or in their positioning relative to their respective housing blanks or relative to other corresponding reference points in their respective housing blanks, then the first housing guide portion and the second housing guide portion are different from each other.

[0023] By using shell blanks with the same structure according to the present invention, economies of scale can be achieved, thereby saving costs.

[0024] The transmission housing according to the invention, or a preferred improvement thereof, is preferably part of a first transmission device. The first transmission device belongs to a series of transmission devices, which also includes a second transmission device. The second transmission device has a second transmission housing designed according to the invention or a preferred improvement thereof. According to the method of the invention, the first and second transmission housings are made from housing blanks with identical structures.

[0025] A transmission series refers to an arrangement of at least two transmissions that are consistent in the expression of at least one technical feature. The first and second transmissions in the current series are consistent in the type of construction of their transmission housings according to the invention. Attached Figure Description

[0026] A preferred embodiment of the present invention is as follows: Figure 1 As shown in the image. Specifically:

[0027] Figure 1 A cross-sectional segment of the transmission device is shown. Detailed Implementation

[0028] Figure 1 The cross-sectional segment shown relates to a planetary segment having a ring gear 101, a rotatable planet carrier 103, planet gears 105, and a sun gear 107. Planet gears 105 mesh with the ring gear 101 and the sun gear 107, respectively.

[0029] The gear ring 101 is part of the transmission housing. The transmission housing also includes a housing cover 111 having a flange that screws onto the gear ring 101. The housing cover 111 also forms a bearing housing for a bearing 113, by which the planetary carrier 103 is rotatably supported.

[0030] A raised portion 115 extends within the housing cover 111. The raised portion 115 is rotationally symmetrical with respect to the axis of rotation of the planetary carrier 103. The raised portion is provided with a continuous threaded hole 117. A sealing plug 119 is screwed into the threaded hole 117.

[0031] The threaded hole 117 can be introduced into the raised portion 115 at any location. Therefore, the housing, in its shown form, can be adapted to various application possibilities beyond the structural variation of the repositioning of the threaded hole 117.
