Description

Technical Field

[0001] The utility model relates to the technical field of bearing cover plate replacement, in particular to a bearing cover plate which is convenient for replacing a bearing shell. Background Art

[0002] A bearing shell is a shell or housing used to mount and support bearings, usually made of metal or alloy. Its main function is to provide support, positioning and protection for the bearing, and to withstand the load and vibration generated by the bearing in the mechanical device. In order to install it quickly and conveniently, a bearing cover plate that is easy to replace is required. The bearing cover plate that is easy to replace is usually a design that aims to make the bearing replacement process easier and more efficient. The bearing cover plate is designed to be easily disassembled and is usually fixed to the machine or equipment using bolts, quick clips or other simple connection methods. Once the bearing needs to be replaced, the operator can quickly remove the bearing cover plate without disassembling the entire machine or other parts of the equipment.

After using the cover plate body, when the bearing is damaged and needs to be replaced, it is no longer necessary to remove the cover plate body from the water jet loom frame, but only to remove the bearing cover from under the cover plate body. By matching the bearing cover and the circular fixing groove with the arc-shaped positioning notch and the arc-shaped fixing notch, the bearing cover can be installed and removed from the cover plate body more quickly, conveniently and accurately, which facilitates maintenance and repair, reduces maintenance time, and improves the use efficiency of the water jet loom.

[0004] However, the technical solution embodiment states that “both ends of the first arc-shaped limit plate 801 are fixedly installed with clamping blocks 9, and both ends of the second arc-shaped limit plate 802 are provided with clamping grooves 10, and the two groups of clamping blocks 9 are respectively clamped in the two groups of clamping grooves 10, and the matching structure of the clamping blocks 9 and the clamping grooves 10 makes it easier to disassemble the first arc-shaped limit plate 801 and the second arc-shaped limit plate 802; the first arc-shaped limit plate 801 and the second arc-shaped limit plate 802 are both provided with arc-shaped slots 11 in annular shapes and equidistantly, and the outer wall of the bearing shell 7 is provided with arc-shaped inserts 12 in a circumferential array, and the arc-shaped limit plates 801 and the second arc-shaped limit plates 802 are provided with arc-shaped inserts 12 in a circumferential array, and the arc-shaped limit plates 801 and the second arc-shaped limit plates 802 are provided with arc-shaped inserts 11 in annular shapes and equidistantly, and the arc-shaped limit plates 801 and the second arc-shaped limit plates 802 are both provided with arc-shaped inserts 12 in a circumferential array, and the arc-shaped limit plates 801 and the second arc-shaped limit plates 802 are provided with arc-shaped inserts 1 ... The shaped plug block 12 is inserted into the arc-shaped slot 11, and the block 9 of the first arc-shaped limit plate 801 is separated from the slot 10 of the second arc-shaped limit plate 802, so that the bearing shell 7 can be disassembled and separated from the first arc-shaped limit plate 801 and the second arc-shaped limit plate 802.

This assembly controls the maximum movement range of the sliding rod 10 to prevent mechanical damage caused by excessive movement.

[0037] Working steps

[0038] After the bearing body 2 is installed on the top of the base 1, the protective cover 3 is slidably connected to the outside of the bearing body 2 to drive the protective cover 3 and the support plate 4 to contact the outside of the base 1 and the bearing body 2. After the connecting sleeve 9 is installed inside the support plate 4 and the base 1, the sliding rod 10 is driven to slide by pressing the pressing block 11, and the fixed ring 12 is driven to move by the sliding of the sliding rod 10. The rotating block 13 is driven to slide in the internal groove of the connecting sleeve 9 by the movement of the fixed ring 12. The connecting sleeve 9 is clamped inside the base 1 by the expansion of the rotating block 13, and the external limit column 17 is connected by sliding inside the support ring 16. The sleeved spring 2 18 and the limiting ring 19 push the limiting column 17 into the interior of the sliding rod 10, thereby fixing the position of the sliding rod 10. When it is necessary to disassemble the connecting sleeve 9, the limiting column 17 is pulled, and the limiting rod 14 slidably connected to the bottom end of the sliding rod 10 and the spring 1 15 elastically cooperate to push it out, so that it can be quickly disassembled. When the sliding plate 7 is driven to move by rotating the threaded rod 6, the movement of the sliding plate 7 drives the sealing ring 8 to contact the outside of the bearing body 2 and the connection between the bearing body 2 and the protective cover 3, thereby increasing the protection of the internal bearing.
