Description

Technical Field

[0001] The present invention relates to the technical field of water jet loom devices, and particularly to a bearing housing structure for the camshaft of a water jet loom. Background Art

[0002] A water jet loom is a shuttleless loom that uses a jet of water to draw the weft yarn through the shed. The frictional traction force of the water jet weft insertion on the weft yarn is greater than that of the air jet weft insertion, and the diffusivity is small, meeting the need for the weft insertion of filaments such as synthetic fibers and glass fibers with a smooth surface. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, the energy consumed by jetting the weft yarn is less and the noise is the lowest. Therefore, water jet looms are widely popularized and applied at present.

[0003] The camshaft in the weft yarn injection structure of a water jet loom generally rotates at a high speed of 800 revolutions per minute. When the convex part of the cam rotates to the highest point, the spring in the water pump will act on the connecting piece and the cam swing rod in the opposite direction, causing the camshaft to have an instantaneous radial jump. Under long-term continuous operation, this jump will directly cause damage to the bearing at the end of the camshaft, shortening the service life of the bearing and requiring regular replacement. When replacing the bearing, many components need to be removed, and the process is complex, time-consuming and laborious. Summary of the Invention

[0004] The present invention designs a bearing housing structure for the camshaft of a water jet loom to solve the problem that the bearing at the end of the camshaft of the existing water jet loom is not convenient for disassembly and replacement.

It further includes a bearing housing. A sleeve hole is provided on the front surface of the end support corresponding to the outer periphery of the end of the camshaft body. The bearing housing includes a cylinder body detachably and fixedly sleeved in the inner cavity of the sleeve hole, and the outer ring of the bearing is fixedly sleeved in the inner cavity of the cylinder body.

[0006] Preferably, the bearing housing further includes a disc body perpendicularly and fixedly connected to the front end of the cylinder body at the back. A plurality of through holes are evenly provided along the circumference near the outer edge on the front surface of the disc body. Threaded holes are respectively provided on the front surface of the end support corresponding to the through holes. Fixing bolts are respectively sleeved in the through holes, and the rear ends of the fixing bolts are respectively threadedly sleeved corresponding to the threaded holes.

[0007] Preferably, the aperture of the sleeve hole is 100 mm, and the outer diameter of the cylinder body is 100 + 0.03 mm.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1-2 , the present invention provides a technical solution for a bearing housing structure of a water jet loom camshaft, including a camshaft body 2, a bearing 3 with an inner ring portion fixedly sleeved on the end of the camshaft body 2, and a shaft end support 1. It further includes a bearing housing 4. A sleeve hole 11 is provided at a position on the front surface of the shaft end support 1 corresponding to the periphery of the end of the camshaft body 2. The bearing housing 4 includes a cylinder body 42 detachably and fixedly sleeved in the inner cavity of the sleeve hole 11, and the outer ring portion of the bearing 3 is fixedly sleeved in the inner cavity of the cylinder body 42.

[0022] In summary, during use, the outer wall of the existing shaft end support 1 can be reamed to process the sleeve hole 11. The type of the original bearing 3 needs to be replaced. The selected bearing 3 can be first sleeved into the inner cavity of the cylinder body 42 in an interference fit manner, and then the cylinder body 42 is inserted into the sleeve hole 11, and at the same time, the new bearing 3 is sleeved on the end of the camshaft body 2, thus completing the assembly operation of the bearing 3. When the bearing 3 needs to be removed and replaced, the bearing 3 and the bearing housing 4 are respectively disengaged from the end of the camshaft body 2 and the sleeve hole 11.

[0023] In this embodiment, the bearing housing 4 further includes a disc body 41 whose back surface is vertically and fixedly connected to the front end of the cylinder body 42. A plurality of through holes 43 are evenly formed in the circumferential direction at a position near the outer edge on the front surface of the disc body 41. Threaded holes 12 are respectively formed in the front surface of the shaft end support 1 at positions corresponding to the through holes 43. Fixing bolts 5 are respectively sleeved in the through holes 43, and the rear ends of the fixing bolts 5 are respectively threadedly sleeved corresponding to the threaded holes 12. The assembly and cooperation of the through fixing bolts 5 with the through holes 43 and the threaded holes 12 enhance the fixed connection strength between the bearing housing 4 and the shaft end support 1.

[0024] In this embodiment, the aperture of the sleeve hole 11 is 100 mm, and the outer diameter of the cylinder body 42 is 100 + 0.03 mm.
