COOLING JACKET WITH SEALANT Russian patent published in 2017 - IPC H02K5/20 H02K9/19 H02K9/20 

FIELD: electricity.

SUBSTANCE: cooling jacket (1, 31) with flowing fluid (14) comprises a casing (2), which has an inner shell (3, 103) and an outer jacket (4, 44, 74, 94, 104, 114). The casing (2) has a hole (6, 46, 56, 86, 96, 106) at one axial end (5, 145), a sealing means (7, 37, 97, 107, 117, 127, 137) that is located in the hole (6, 46, 56, 86, 96, 106, 146) and radial deformation (8, 58, 68, 98, 108, 118) that connects the casing (2) to the sealing means (7, 37, 97, 107, 117, 127, 137). The radial deformation (8, 58, 68, 98, 108, 118) passes through the hole (6, 46, 56, 86, 96, 106). The invention relates to a casing for a cooling jacket. It is possible to connect the casing (2) due to the radial deformation (8, 58, 68, 98, 108, 118) with the sealing means (7, 37, 97, 107, 117, 127, 137) for the cooling jacket (1, 31); to the sealing means (7, 37, 97, 107, 117, 127, 137), which is adapted to be connected to the casing (2) by the radial deformation (8, 58, 68, 98, 108, 118); to the machine, in particular an electrical machine comprising a cooling jacket (1, 31); to the method for manufacturing a cooling jacket (1, 31), in which a connection is made between the casing (2) and the sealing means (7, 37, 97, 107, 117, 127, 137); to the method for manufacturing a machine, in particular an electric machine, in which the tightness of the cooling jacket (1, 31) is checked before attaching the bearing shield (112, 122) to the cooling jacket (1, 31).

EFFECT: reducing the unintended exit of the fluid flowing in the cooling jacket under various operating conditions.
