Bearing housing and bearing assembly

Abstract

This invention discloses a bearing housing and a bearing assembly. The bearing housing includes a base, a threaded rod, a locking screw, and a cover. The base has a first side groove and a second side groove formed on opposite sides. The threaded rod has a through-hole formed radially therein, and the threaded rod passes laterally through the first side groove in the thickness direction, so that the threaded hole communicates with the first side groove. The locking screw is screwed into the threaded hole of the threaded rod, so that they can rotate together relative to the first side groove. The cover is detachably mounted on the base and inserted into the first side groove and the second side groove. The locking screw and the threaded rod can be rotated to an upright position, so that the locking screw can be tightened to press against the cover.

7. The bearing housing as claimed in claim 1, wherein, The base has a plurality of longitudinal positioning posts spaced apart from each other on its bottom edge, and each of the longitudinal positioning posts is parallel to the height direction.

8. The bearing housing as described in claim 7, wherein, The bearing housing includes a plurality of longitudinal screws inserted into the base along the height direction. The plurality of longitudinal screws are respectively located on opposite sides of the first side groove and the second side groove, and portions of the plurality of longitudinal screws extend through the bottom edge of the base to be located on opposite sides of the plurality of longitudinal positioning posts.

9. The bearing housing as claimed in claim 1, wherein, The base has a first side surface and a second side surface located on opposite sides, and the base is formed with: a plurality of transverse screw holes recessed in the second side surface along the thickness direction; and a plurality of transverse nut holes recessed in the first side surface along the thickness direction and respectively communicating with the plurality of transverse screw holes; wherein, the bearing housing includes a plurality of transverse nuts and a plurality of transverse screws, the plurality of transverse nuts being non-rotatably disposed within the plurality of transverse nut holes, and the plurality of transverse screws being able to pass through the plurality of transverse screw holes along the thickness direction to be respectively screwed into the plurality of transverse nuts.

10. The bearing housing as claimed in claim 9, wherein, The base has a protruding lower positioning ring formed on the second side surface along the edge of the lower bearing groove, and the cover has a corresponding upper positioning ring; wherein, when the cover is inserted into the first side groove and the second side groove with the first side arm and the second side arm respectively, the lower positioning ring and the upper positioning ring correspond to each other to form a circular structure.

11. The bearing housing as claimed in claim 1, wherein, The second side arm has: a pivot detachably inserted into the second side groove; an upper nut hole recessed from the surface of the second side arm away from the first side arm; and an opening located on the opposite side of the pivot and communicating with the upper nut hole; wherein the bearing housing includes an upper nut that is non-rotatably disposed within the upper nut hole, and the opening is for a screw to be inserted to lock the upper nut.

12. A bearing assembly comprising: A bearing housing, comprising: a base having: a bearing lower groove; The bearing comprises: a first side groove and a second side groove, recessed along a height direction and respectively formed on opposite sides of the lower groove of the bearing; a threaded rod having a through-hole formed radially therefrom; wherein the threaded rod passes laterally through the first side groove along a thickness direction perpendicular to the height direction, so that the threaded hole of the threaded rod communicates with the first side groove; a locking screw having a head and a threaded portion connected to the head; wherein the locking screw is screwed into the threaded hole of the threaded rod with the threaded portion, so that the locking screw and the threaded rod can rotate together relative to the first side groove between a lateral upright position and a vertical upright position; and a cover detachably mounted on the base, and the cover having: A bearing upper groove, the shape of which corresponds to the bearing lower groove; a first side arm and a second side arm, respectively detachably inserted into the first side groove and the second side groove; and a bearing; wherein, when the cover is inserted into the first side groove and the second side groove with the first side arm and the second side arm respectively, so that the bearing is embedded in the bearing lower groove and the bearing upper groove, the locking screw and the threaded rod can be rotated to the upright position, so that the head is located in the first side arm and can be tightened to press the cover, thereby placing the bearing seat in a locked position.
