Abstract
A gear housing for a motor is fixed to a motor main body driving a rotary shaft. The gear housing contains a worm wheel and a worm connected to the rotary shaft. Three mounting feet to be fixed to a mounting member are formed at intervals and protrude from a first side surface of the gear housing. A bulge portion bulges outward on the first side surface of the gear housing to expand the internal space. The bulge portion has side walls, which are installed to protrude from the outer side surface constituting the side walls of the bulge portion, and an upper wall, which connects the distal ends in the protruding direction of the side walls. The three mounting feet are connected by the side walls and the upper wall.
Claims17
A gear housing for a motor, wherein the gear housing is directly fixed to a motor main body, which drives a rotary shaft, contains a reduction gear connected to the rotary shaft, and has a first side surface, the gear housing comprising:
- a plurality of mounting feet formed at intervals to protrude from the first side surface and to be fixed to a mounting member;
- a bulge portion formed on the first side surface and bulging outward and forming an expanded internal space in the gear housing;
- and
- a cylindrical support cylinder portion, which supports an output shaft rotated integrally with the reduction gear,
- wherein
- the bulge portion has a plurality of side walls installed to protrude from the first side surface and an upper wall, which connects distal ends in the protruding direction of the side walls,
- the mounting feet are connected together by the side walls and the upper wall, and
- the support cylinder portion is connected to the bulge portion.
A motor comprising:
- a motor main body, which drives a rotary shaft;
- a reduction gear connected to the rotary shaft;
- and
- a gear housing, which is directly fixed to the motor main body, contains the reduction gear, and has a first side surface, wherein
- the gear housing includes:
- a plurality of mounting feet formed at intervals to protrude from the first side surface and to be fixed to a mounting member;
- a bulge portion formed on the first side surface and bulging outward and forming an expanded internal space in the gear housing;
- and
- a cylindrical support cylinder portion, which supports an output shaft rotated integrally with the reduction gear, wherein
- the bulge portion has a plurality of side walls installed to protrude from the first side surface and an upper wall, which connects distal ends in a protruding direction of the side walls, and
- the mounting feet are connected by the side walls and the upper wall, and
- the support cylinder portion is connected to the bulge portion.
A gear housing for a motor, wherein the gear housing is fixed to a motor main body, which drives a rotary shaft, contains a reduction gear connected to the rotary shaft, and has a first side surface, the gear housing comprising:
- a bulge portion formed on the first side surface and bulging outward and forming an expanded internal space in the gear housing;
- and
- a cylindrical support cylinder portion connected to the bulge portion, the support cylinder portion supporting an output shaft rotated integrally with the reduction gear, wherein
- the bulge portion has a plurality of side walls installed to protrude from the first side surface and an upper wall, which connects distal ends in the protruding direction of the side walls,
- the support cylinder portion has an inner cylinder, which protrudes inward from the upper wall and
- the side walls of the bulge portion;
- further comprising a plurality of mounting feet formed at intervals to protrude from the first side surface and to be fixed to a mounting member, wherein the mounting feet include three mounting feet, and the side walls continuously connect the three mounting feet so that a space is formed among the three mounting feet and the inner cylinder are connected by a plurality of inner ribs.
