Problems solved by technology

Also, there is the problem that assemblers do not always use mounting guards, even when supplied, because there is not always quality control on the assembly line to ensure that guards are used
There is also the danger that the assembler will forget to set the installation guard before installing the shaft

Embodiment Construction

[0025] Figures 1a-1b show a transport and installation protection device 1 according to the invention. The transport and installation protection device 1 comprises a plug-in component 2 and a mounting protection sleeve 3 , which are connected to one another via a coupling component 8 . According to the embodiment shown in Figures 1a-1b, this coupling member 8 is an annular flexible connecting member. In FIG. 1 a the plug member 2 is inserted into the mounting protection sleeve 3 , while in FIG. 1 b the plug member 2 is withdrawn from the mounting protection sleeve 3 . Arrow A indicates the direction in which the plug member 2 is pulled out from the mounting protection sleeve 3 .

[0026] In this preferred embodiment, the plug member 2 is in the form of an elongated hollow cylinder having a distal 4 and a proximal 5 end, viewed along the direction of insertion of the plug member 2 into the mounting shield sleeve 3 . In this preferred embodiment, the distal end 4 of the plug m...

Abstract

The present invention relates to a transport and mounting protection device for a shaft passage opening in a housing containing rotary parts, preferably a differential gear housing, comprising a mounting protection sleeve which is arranged to be inserted, before mounting of a shaft, and maintained in said shaft passage opening and which is arranged to be broken to allow, after mounting of the shaft, said mounting protection sleeve to be removed from the shaft previously inserted through said mounting protection sleeve, and a plug element for sealing said shaft passage opening in the absence of a shaft inserted therein. Said mounting protection sleeve and said plug element are interconnected by a loop-shaped flexible connection element, which has a length that allows the plug element to be insertable into the mounting protection sleeve by an axial motion relative to the same. The present invention further relates to a method of protecting, during mounting, a sealing ring which is mounted in a shaft passage opening of a housing containing rotary parts.

Description

technical field [0001] The present invention relates to a transport and installation protection device for the shaft passage opening, said shaft passage opening being located in a housing containing a rotating part, preferably a differential gearbox, said transportation and installation protection device comprising: a mounting guard sleeve configured to be inserted into and retained in said shaft passage opening prior to mounting the shaft, and configured to be breakable after mounting the shaft to allow said mounting guard sleeve from having been inserted through said shaft passage opening and a plug member for sealing said shaft passage opening when no shaft is inserted into said shaft passage opening. Furthermore, the invention relates to a method of protecting a sealing ring installed in a shaft channel opening of a housing accommodating a rotating part during installation. Background technique [0002] In the market, different types of housings, such as gearbox housing...
