AI Technical Summary

Problems solved by technology

In some cases, if the relative positioning of the gears relative to each other does not fall within certain tolerances, the motor cannot satisfactorily drive the output crown wheel due to gear binding or incorrect meshing
In addition, if the components are not properly aligned, considerable undesired forces can be applied to the gears and other components during operation of the operator reducing life expectancy
Over time, chassis plates can loosen allowing components to move relative to each other, causing problems such as increased friction, increased play and misalignment

Embodiment Construction

[0044] The embodiment of the present invention provides an underframe-less door operation drive motor assembly, which has an integrated fixing surface so as to be directly and fixedly connected to the roller shutter drum shaft or the combination door or the inclined door drive rail. The operating part includes a single-piece molded or cast part, which has a drive motor spindle bearing support, a gearbox housing with a gearbox bearing support, a support for an axially rotatable output drive part, and a fixed surface, It provides predetermined and aligned positions for mounting the corresponding components to maintain these components in an interactive position relative to each other and relative to the fixed surface. The molded part or casting may also include a support for the door position sensor assembly so that the door position sensor assembly can be installed in alignment with other drive assembly components in an interworking relationship. Therefore, the need to adjust th...

Abstract

Embodiments of the present invention provide a chassis-less door operator drive motor assembly with an integral fixing surface for direct fixing connection with a roller door drum axle or a sectional door or tilt door drive track. The operator comprises a one piece moulding or casting that has a drive motor spindle bearing support, a gear box casing with a gear box bearing support, a bearing support for an axially rotatable output drive component and the fixing surface, which provide pre-defined and aligned positions for mounting the respective components to maintain these components in interworking positions relative to each other and to the fixing surface. Thus the need to adjust relative positions of the mounted components to maintain intended working interrelationships is either avoided or substantially minimized.

Description

Technical field [0001] The present invention relates to door operators and in certain embodiments to door operators for rolling doors or combination / tilting doors. The operating element can be applied to a moving barrier, such as a door in general, and the use of the term door operating element in the following is understood to be used for all barrier types of operating elements that need to be moved to open and close, where the barrier includes a door, such as a garage Doors and / or industrial doors or gates, etc. Background technique [0002] In the applicant's Australian Innovation Patent No. 2010101382, a door operating member that can be completely installed in the curtain drum of a rolling door is disclosed. An embodiment of the present invention relates to an improved form of this type of door operator. This type of door operator is made of discrete single parts that are mounted to a chassis forming part of the door operator. This type of door operator utilizes multiple ...
