Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, and in particular to a high-strength precision bearing housing. Background Technology

[0002] Bearing housings are commonly used components in mechanical transmissions. A bearing is housed within the housing, and a shaft is housed within the bearing. The housing provides support for the outer ring of the bearing. In related technologies, a bearing housing includes a connecting seat and a bearing sleeve. The connecting seat has several connecting holes, through which screws are inserted to connect the bearing housing to other equipment. The bearing sleeve is integrally connected to the connecting seat, and has bearing holes for the bearing to pass through.

[0003] When using a bearing housing, the connecting seat is connected to other equipment via screws. The bearing passes through the bearing hole, and the outer ring of the bearing abuts against the wall of the bearing hole. In this way, the bearing is fixed to other equipment through the bearing housing. However, when the bearing housing is fixed to an object, the surface of the object may not be flat, nor may it be parallel to the axis of the rotating mechanical body. Therefore, shims need to be added to the bottom of the bearing housing to adjust it during the installation process. However, it is necessary to try shims of different thicknesses to find the right fit. To solve the above problems, a high-strength precision bearing housing that can adjust the position of the bearing base is provided. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, the present invention provides a high-strength precision bearing housing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-strength precision bearing housing includes a fixed base, a fixed frame rotatably connected to the top of the fixed base, and a bearing base movably connected to the fixed frame; threaded rods are symmetrically arranged on both sides of the fixed frame, and sliding blocks are provided on the bearing base, with the sliding blocks slidably connected to the threaded rods.

[0007] Preferably, an adjusting nut is threaded onto the threaded rod, and the sliding block is positioned above the adjusting nut.

[0008] Preferably, a locking nut is threaded onto the threaded rod, and the locking nut is positioned above the sliding block and abuts against the sliding block.

[0009] Preferably, the structure includes a lower base and an upper base, with the sliding block disposed on the lower base.

[0010] Preferably, a rotating shaft is fixedly connected to the bottom of the fixing frame, and the rotating shaft is rotatably connected to the fixing base.

[0011] Preferably, a worm gear is provided on the rotating shaft inside the fixed seat, and a worm is rotatably connected inside the fixed seat, the worm meshing with the worm gear.

[0012] Preferably, the lower base and the upper base are detachably and fixedly connected by a locking bolt.

[0013] Preferably, the lower base end face is provided with a positioning groove, and the upper base end face is provided with a positioning block, the positioning block being engaged with the positioning groove.

[0014] Preferably, the lower base has a lower threaded hole, and the upper base has an upper threaded hole at a corresponding position. The lower threaded hole and the upper threaded hole are fixedly connected by a locking bolt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Rotate the fixing bracket to adjust its angle, and tighten the adjusting nut to the preset height. At this time, the sliding block is moved above the adjusting nut through the sliding block and the threaded rod. Tighten the locking nut into the threaded rod so that the locking nut abuts against the sliding block, thereby installing the bearing base to the preset height. With the adjustment of the bearing base angle, the bearing base can be installed so that the shaft center is always concentric with the shaft center of the rotating body, without the need to adjust the bearing base with shims.

[0017] 2. The positioning block and positioning slot are engaged to achieve pre-positioning of the lower base and the upper base. The base and the upper base can be detachably fixed by the locking bolt, which makes it easy to remove or disassemble the bearing from the bearing base.

[0018] In summary, this utility model overcomes the shortcomings of the prior art, has a reasonable design, and makes the bearing base axis concentric with the axis of the rotating body by adjusting the position and angle of the bearing base. It has high social use value and application prospects. Attached Figure Description

[0029] The bearing base 2 includes a lower base 21 and an upper base 22. The lower base 21 has a sliding block 211 on its side wall. The sliding block 211 is slidably connected to the threaded rod 111. An adjusting nut 112 is provided on the threaded rod 111 below the sliding block 211. When the adjusting nut 112 is rotated to a suitable position, the sliding block 211 abuts against the upper part of the adjusting nut 112. A locking nut 113 is threadedly connected on the threaded rod 111 above the sliding block 211. When the locking nut 113 is rotated to abut against the upper part of the sliding block 211, the sliding block 211 can be fixed.

[0030] Furthermore, a rotating shaft 1101 is fixedly connected to the bottom of the fixed frame 11. The rotating shaft 1101 is rotatably connected to the fixed seat 1. A worm gear 1102 is provided on the rotating shaft 1101 inside the fixed seat 1. A worm 1103 is rotatably connected inside the fixed seat 1. The worm 1103 is meshed with the worm gear 1102. A turning block 1104 is provided at the outer end of the worm 1103.

[0031] The fixed frame 11 is rotatably connected to the fixed base 1. At this time, the fixed frame 11 is rotated to adjust its angle. The adjusting nut 112 is screwed to the preset height. The sliding block 211 is movably connected to the threaded rod 111 and placed above the adjusting nut 112. The locking nut 113 is screwed into the threaded rod 111 so that the locking nut 113 abuts against the sliding block 211, thereby installing the bearing base 2 to the preset height. With the adjustment of the angle of the bearing base 2, the axis of the bearing base 2 can always be concentric with the axis of the rotating body after installation, without the need to adjust the bearing base with shims.

The sliding block 211 is movably connected to the threaded rod 111 and placed above the adjusting nut 112. The locking nut 113 is screwed into the threaded rod 111 so that the locking nut 113 abuts against the sliding block 211, thereby installing the bearing base 2 to the preset height. With the adjustment of the angle of the bearing base 2, the axis of the bearing base 2 can always be concentric with the axis of the rotating body after installation.
