Description

Technical Field

[0001] The utility model relates to the technical field of rapier wheels, in particular to a rapier wheel with inlaid teeth. Background Art

[0002] The rapier wheel is one of the key parts of a rapier loom. When the rapier loom is working, the rapier wheel rotates reciprocally, and drives the rapier to reciprocate and shuttle at high speed through the engaged rapier belt.

[0003] The existing rapier wheels are usually of an integral structure. During long-term use, the convex teeth of the rapier wheel are usually worn and replaced. However, if one convex tooth of the rapier wheel is damaged, the whole rapier wheel needs to be replaced, which causes great waste. Moreover, the existing rapier wheels are usually made of integral aluminum alloy material or integral plastic material. The integral aluminum alloy material has poor wear resistance, low service life, high cost, and cannot be recycled; the integral plastic material has low structural strength and is prone to fatigue deformation during high-speed operation. Summary of the Utility Model

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a rapier wheel with inlaid teeth, which is used to solve the problems in the prior art that the rapier wheel is of an integral structure, has a short service life, and can only be replaced as a whole.

[0005] To achieve the above purpose and other related purposes, the present utility model provides a rapier wheel with inlaid teeth, including a disk body and convex teeth. A plurality of tooth grooves are evenly formed on the circumferential outer edge of the disk body, and the convex teeth are installed in the tooth grooves by interference fit;

[0006] First mounting grooves concentric with the disk body are arranged on both sides of the disk body. Second mounting grooves cooperating and communicating with the first mounting grooves are arranged on both sides of the convex teeth. Through holes are formed at the positions of the convex teeth corresponding to the second mounting grooves. Reinforcing rings are installed in the first mounting grooves and the second mounting grooves, and the reinforcing rings are injection-molded or glued in the first mounting grooves.

[0007] In an embodiment of the present utility model, the convex teeth are in a "T" shape or a "dry" shape. The wider end of the convex teeth is inlaid in the tooth grooves, and the narrower end of the convex teeth protrudes out of the tooth grooves.

[0008] In an embodiment of the present utility model, the depth and width of the second mounting grooves are both larger than those of the first mounting grooves.

[0009] In an embodiment of the present utility model, the disk body includes an inner ring and an outer ring. The cross section of the outer ring is in a "C" shape. The outer ring surrounds the circumferential outer edge of the inner ring, and the tooth grooves are formed on the circumferential outer edge of the outer ring.

[0010] In an embodiment of the present invention, the outer ring is packaged on the outer ring of the inner ring by injection molding.

[0011] In an embodiment of the present invention, an axial hole is provided at the center of the disc body, and a plurality of weight-reducing holes are provided on the surface of the disc body.

[0017] 2. The utility model further fixes the convex teeth by arranging reinforcement rings on both sides of the disc body, so that the convex teeth are interconnected through the reinforcement rings. When a certain convex tooth is subjected to force, the force can be distributed to other parts to prevent the certain convex tooth from deforming and displacing, thereby preventing the convex tooth from loosening or falling off; at the same time, the reinforcement ring makes the connection between the convex tooth and the disc body more firmly, and the reinforcement ring can also further improve the structural strength of the sword wheel.

[0018] 3. The reinforcing ring is in a fluid state during injection molding. By opening a through hole on the convex tooth, the reinforcing ring can be molded on both sides of the disc body at the same time, which is easy to operate; and the reinforcing ring can further limit and connect each convex tooth to prevent the convex tooth from falling.
