Abstract
A steering device for an OHT according to some example embodiments of the present inventive concepts includes: an LM block; a steering plate fixedly installed to the LM block and provided with an insertion groove; a link installed in the insertion groove of the steering plate and tilted; a main bearing having an outer circumferential surface in contact with the link to reduce friction when the link is tilted; and a guide roller rotatably installed on a protrusion protruding from the link.
Claims20
A steering device for an OHT, the steering device comprising:
- a linear motion (LM) block;
- a steering plate fixedly installed to the LM block, the steering plate including one or more inner surfaces at least partially defining an insertion groove in the steering plate;
- a link tiltably installed in the insertion groove of the steering plate;
- a main bearing having an outer circumferential surface in contact with the link, the main bearing configured to reduce friction when the link is tilted in relation to the steering plate;
- and
- a guide roller rotatably installed on a protrusion protruding from the link.
A steering device for an OHT, the steering device comprising:
- a linear motion (LM) block;
- a steering plate fixedly installed on an upper surface of the LM block, the steering plate including one or more inner surfaces at least partially defining an insertion groove in an upper surface of the steering plate;
- a link that is at least partially within the insertion groove and is configured to be tilted in response to an external force being applied to the link;
- a main bearing between the steering plate and the link;
- a guide roller rotatably installed on an installation protrusion protruding from the link;
- a cover configured to cover the main bearing and the insertion groove of the steering plate;
- and
- a fixing member extending through the steering plate, the fixing member configured to fix the main bearing in place.
A steering device for an OHT, the steering device comprising:
- a linear motion (LM) block;
- a steering plate immovably installed to the LM block, the steering plate including one or more inner surfaces at least partially defining an insertion groove in the steering plate;
- and
- a link tiltably installed in the insertion groove of the steering plate such that the link is configured to rotate in relation to the steering plate around a central axis of the link at least partially within the insertion groove,
- wherein an interval between an outer side surface of the link and a side surface of the insertion groove is between about 1 mm and about 3 mm.
