Abstract
A weldment for attaching mounting brackets and bases to electric motors includes an internal doubler element that is positioned within a motor shell and attached to the inner wall surface of the motor shell. A mounting bracket or base positioned on the outer wall surface of the motor shell is attached to the internal doubler element by a plug weld. The internal doubler element is positioned to increase the strength of the shell at critical stress areas. In addition to utilizing the internal doubler element, the mounting bracket is positioned to be aligned with and adjacent the lap weld seam of the motor shell.
Claims60
An assembly for mounting an electric motor to a support comprising:
- a motor shell for housing an electric motor, the motor shell having a longitudinal center;
- a mounting bracket adjacent an outer surface of the motor shell at a first location;
- an internal doubler element adjacent an inner surface of the motor shell, located on one side of the longitudinal center thereof and in alignment with an end portion of the mounting bracket adjacent the outer surface of the motor shell;
- and
- a connection between the mounting bracket and the internal doubler element, whereby the internal doubler element reinforces the motor shell at local areas which are subject to stress.
An electric motor which comprises:
- a motor shell having an inner and an outer surface and a longitudinal center;
- a stator positioned in the motor shell;
- a mounting bracket positioned adjacent the outer surface of the motor shell at a first, location;
- an internal doubler element positioned adjacent the inner surface of the motor shell, located on one side of the longitudinal center thereof and in alignment with an end portion of the mounting bracket adjacent the outer surface of the motor shell;
- and
- a connection between the mounting bracket and the internal doubler element whereby the internal doubler element reinforces the motor shell at local areas which are subject to stress.
A method of securing a mounting bracket to an electric motor, which comprises the steps of:
- providing an electric motor having a motor shell, the motor shell having a longitudinal center;
- positioning an internal doubler element adjacent an inner surface of the motor shell at a first location in which the internal doubler element is located on one side of the longitudinal center;
- positioning a mounting bracket so that a portion of the mounting bracket lies adjacent the outer surface of the motor shell at the first location so as to be aligned with the internal doubler element;
- and
- connecting the portion of the mounting bracket to the internal doubler element, whereby the internal doubler element reinforces the motor shell at local areas which are subject to stress.
An assembly for mounting an electric motor comprising:
- a motor shell for housing an electric motor, the motor shell including a lap weld seam;
