Problems solved by technology

However, a housing with such cooling fins is many times more expensive than a correspondingly designed housing without cooling fins
In addition, the configuration of the cooling fins also leads to a substantial increase in the dead weight of the housing, which is undesirable in many cases

Embodiment Construction

[0016] figure 1 A transmission 1 according to an embodiment of the invention is shown, wherein this is a spur gear designed as a bevel spur gear. Obviously, however, the specific transmission type is not critical to the invention. The transmission 1 has a housing 2 which is divided into an upper housing part 2a and a lower housing part 2b. The upper housing part 2 a and the lower housing part 2 b are here symmetrically constructed and can be cast in the same mold, wherein this is not mandatory. The transmission 1 also comprises a drive shaft 3 and a driven shaft 4 through which the drive power enters the transmission 1 and which is connected to a device not shown, for example a conveyor belt device (for example only). A cooling structure in the form of a cooling element 5 made of open-celled metal foam is arranged on the outer side of the housing 2 , the cooling structure being fastened on the housing 2 as a separate component. The cooling element 5 is currently designed in...

Abstract

The invention relates to a transmission device (1) having a housing (2) made of a metal material, which is provided with a cooling structure. The device is characterized in that the cooling structurehas a cooling element (5) made of open-cell metal foam, and the cooling element is fastened to the housing (2), in particular to the outer surface of the housing. The invention further relates to a method for manufacturing such a transmission device.

Description

technical field [0001] The invention relates to a transmission having a housing made of metallic material which is provided with a cooling structure. Furthermore, the invention relates to a method for producing such a transmission. Background technique [0002] In the field of transmission technology it is important that the heat accumulated within the transmission be dissipated from the transmission housing in order to be able to continuously ensure trouble-free operation of the transmission. For this purpose, the transmission can be equipped with an active cooling device. Alternatively or additionally, a passive cooling system can be provided, which is achieved, for example, by increasing the surface area of ​​the housing by providing cooling structures in the form of cooling fins. However, a housing with such cooling fins is many times more expensive than a correspondingly embodied housing without cooling fins. Furthermore, the configuration of the cooling fins also le...
