Description

Technical Field

[0001] This utility model relates to the technical field of water seal installation tools, specifically a water seal installation tool. Background Technology

[0002] The rolling mill rolls in the steel mill require a large amount of cooling water during operation. To prevent water from entering the roll bearings, a water seal is installed on the outside of the bearing housing. A water seal ring is installed on the side of the bearing housing near the roll. A labyrinth ring is installed on the end face of the roll body. The WA-500 water seal is clamped on the water seal ring, and its lip contacts the labyrinth ring to seal the water and prevent cooling water from entering the bearing in the bearing housing.

[0003] Due to space constraints, the installation diameter of the water seal ring is designed to be 520mm, and the applicable water seal specification is WA-500. This specification of water seal has an inner diameter of 450mm and an applicable diameter of 480-530mm. The water seal needs to be stretched by 230mm in circumference to fit into the water seal ring. In addition, the bearing housing is vertical during installation, and the water seal needs to be lubricated for slippage, making installation difficult. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing water seals require a circumference increase of 230mm to fit into the water seal ring, and the bearing housing is vertical during installation, while the water seal needs to be oiled for slippage, making installation difficult.

[0005] To solve the above problems, the technical solution adopted by this utility model is a water seal installation tool, including a positioning ring. A centering shaft is fastened to the centering ring in the middle by a threaded connection. A half ring is rotatably provided on the outside of the centering shaft next to the positioning ring. A bevel is fixed on the outer edge of the half ring. A retaining edge is fixed on one side of the bevel. A retaining ring is fixed on one side of the positioning ring near the edge. Several threaded holes are opened on the side of the retaining ring, and set screws are threaded into each of the threaded holes.

[0006] As a further embodiment of this utility model: the side of the positioning ring is provided with a groove at the set screw to facilitate tightening the set screw.

[0007] As a further embodiment of this invention: a pair of handles are fixed on one side of the half ring to facilitate the rotation of the half ring.

[0008] As a further embodiment of this utility model: several blocks are fixed on the outer side of the retaining ring for positioning the water seal sleeve.

[0009] As a further embodiment of this utility model, a water seal sleeve is provided on the outer side of the half-ring.

[0010] As a further embodiment of this utility model: a bearing seat is provided on one side of the positioning ring, and a water seal mounting groove is provided on one side of the bearing seat near the edge for installing a water seal sleeve for sealing.

[0011] Compared with the prior art, the advantages of this utility model are as follows: This application adds a positioning ring and a half-ring. The positioning ring is fixed in the inner hole of the water seal ring, and the half-ring can be rotated to easily install the water seal into the water seal ring. This tool is lightweight, easy to operate, and will not damage the water seal when installing it. It can reduce labor intensity and improve work efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0021] Combined with appendix Figure 1-4It can be seen that the positioning ring 1 is included. A centering shaft 2 is fastened to the middle of the positioning ring 1 by a threaded connection. A half ring 3 is rotatably provided on the outside of the centering shaft 2 next to the positioning ring 1. An inclined edge 4 is fixed on the outer edge of the half ring 3 to facilitate the installation of the water seal sleeve 11. A retaining edge 5 is fixed on one side of the inclined edge 4 to block the installed water seal sleeve 11 and prevent it from falling off. A retaining ring 6 is fixed on one side of the positioning ring 1 near the edge to block the installed water seal sleeve 11. Four threaded holes are opened on the side of the retaining ring 6, and set screws 7 are threaded into each of the threaded holes to facilitate fixing the positioning ring 1 to one end of the bearing seat 12.

[0022] The positioning ring 1 has a slot 8 on its side at the set screw 7 to facilitate tightening the set screw 7; a pair of handles 9 are fixed on one side of the half ring 3 to facilitate rotating the half ring 3; several blocks 10 are fixed on the outside of the retaining ring 6 to position the water seal sleeve 11; the water seal sleeve 11 is provided on the outside of the half ring 3; a bearing seat 12 is provided on one side of the positioning ring 1, and a water seal installation groove 13 is provided on one side of the bearing seat 12 near the edge to install the water seal sleeve 11 for sealing.

[0023] The working principle of this application is as follows: When installing the water seal sleeve, firstly, the positioning ring 1 is firmly fixed to one end of the bearing seat 12 by using the threaded hole and the set screw 7. Then, the water seal sleeve 11 is placed on the outer side of the half ring 3. Through the cooperation of the inclined side 4 and the stop 5, a part of the water seal sleeve 11 is first pressed into the water seal installation groove 13. Then, the handle 9 is turned to rotate the half ring 3, so that it can drive the inclined side 4 and the stop 5 to rotate, thereby pressing the water seal sleeve 11 completely into the water seal installation groove 13. The stop block 10 can effectively prevent the pressed water seal sleeve 11 from falling out of the groove. After the installation is completed, the set screw 7 can be loosened and the tool can be removed.
