Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of couplings, in particular to a new type of coupling. Background Art
[0002] Roller tables are an indispensable part of hot rolling production, and the rotation of roller tables must be achieved by connecting the motor with a coupling. According to the on-site production situation, the drum gear coupling meets the on-site use requirements due to its high load-bearing capacity, large angular displacement compensation, improved tooth contact conditions, high transmission efficiency and compact structure.
[0003] In the prior art, however, as the use time increases, the coupling at the roller end often breaks due to the wear of the strip buckle, the straight mouth positioning of the roller frame, the wear of the bearing seat body, and other factors, and the service life is continuously shortened. Moreover, the breaking of teeth directly affects the quality of the strip steel, and when the coupling needs to be replaced, the coupling is heavy, and the replacement is cumbersome and inconvenient for the operator to operate. In view of this, we have introduced a new coupling. Utility Model Content
[0004] The purpose of the utility model is to provide a new coupling to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new coupling, comprising: a half coupling A;
[0006] A half-coupling B is provided on one side of the half-coupling A, an integrated flange is provided on one side of the half-coupling B, and one side of the integrated flange is connected to one side of the half-coupling A. A sealing mechanism is provided between the integrated flange and the half-coupling B, and the space between the integrated flange and the half-coupling B is sealed by the sealing gasket of the sealing mechanism.
[0007] Preferably, the sealing gasket is located on the surface of the half-coupling B, and the surface of the sealing gasket is in contact with the integrated flange.
[0008] Preferably, screw holes are provided on the surfaces of the half-coupling A and the integrated flange, and bolts are provided inside the screw holes for fixing the half-coupling A and the integrated flange.
[0009] Compared with the prior art, the utility model has the following beneficial effects: compared with the old coupling, the new coupling modified by chip cutting is lighter in weight, has the required load-bearing capacity, has a longer service life, is compatible with the old coupling, and is quicker and more convenient to replace;
[0010] The weight of the new coupling is about 1 / 2 of the original coupling, the cost is lower, and it is safer to install after heating, without the risk of the coupling rolling down and hitting the ground. Secondly, the service life is about twice as long as the original one. The coupling range where teeth are often broken is about No. 28 in front of the machine to No. 42 in the back of the machine, with 70 rollers. The cost of one coupling is about 2,000 yuan, so replacing the new coupling can save 140,000 yuan. Due to the reduction in material and the replacement of heating speed, each replacement of the coupling can save about 20 minutes, that is, the replacement can save 1,400 minutes of work, about 24 hours.
[0011] Heat half coupling A to 198℃ and install it on the roller shaft head. Move the integrated flange to the end of half coupling B. Then heat half coupling B to 198℃ and install it on the motor end. After cooling, apply dry oil on the integrated flange. Use sealing gasket to form a seal. Then, align it with half coupling A through straight mouth and connect and tighten it with M10 tapped hole bolts to complete the installation, which is more convenient to use. The thickness of both sides of half coupling A and half coupling B3 is reduced by 23mm per circle, which can reduce the weight while ensuring that the strength of use will not be affected, meeting the requirements of on-site use.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] See also Figure 1The utility model provides a technical solution: a new coupling, including: a half-coupling A1, which is cut from a carbon steel round bar in one piece and then modulated, with 14 11mm through holes and straight-mouth positioning at the end. A half-coupling B3 is arranged on one side of the half-coupling A1. The half-coupling B3 is modified from the original coupling, and the end is cut 23mm up and down to ensure the performance of the half-coupling B3 while reducing the weight for easy installation. An integrated flange 2 is arranged on one side of the half-coupling B3, and one side of the integrated flange 2 is connected to one side of the half-coupling A1. A sealing mechanism is arranged between the integrated flange 2 and the half-coupling B3, and the space between the integrated flange 2 and the half-coupling B3 is sealed by the sealing gasket 4 of the sealing mechanism.
[0016] The sealing gasket 4 is located on the surface of the half coupling B3, and the surface of the sealing gasket 4 contacts the integrated flange 2. The integrated flange 2 is modified from the flange of the original GⅡCL9 coupling. The end retaining ring is directly integrated with the body, and has 14 Φ11mm through holes and straight mouth positioning, and the inner oil groove has a sealing gasket 4. There is a gap between the half coupling A1 and the half coupling B3. By setting the sealing gasket 4, the gap between the half coupling A1 and the half coupling B3 can be sealed to avoid leakage.
[0017] Screw holes are provided on the surfaces of the half coupling A1 and the integrated flange 2, and bolts 5 are provided inside the screw holes for fixing the half coupling A1 and the integrated flange 2. The bolts 5 are M10 tapped holes, 12.9 grade, 55 mm long, and black.
[0018] Specifically, when in use, the half coupling A1 is cut from a carbon steel round bar in one piece, and then modulated, with 14 11mm through holes and straight-mouth positioning at the end; the one-piece flange 2 is modified from the original GⅡCL9 coupling with its own flange, and the end retaining ring is directly integrated with the body, with 14 Φ11mm through holes and straight-mouth positioning, and the inner oil groove is provided with a sealing gasket 4; the half coupling B3 is modified from the original coupling, and the end is cut 23mm up and down, which ensures the performance of the half coupling B3 while reducing the weight and facilitating installation; the M10 tapped hole bolt 5 is 12.9 grade, 55mm long, and black; compared with the old coupling, this new coupling modified by chip cutting is lighter, has the required load-bearing capacity, and has a longer service life, and is compatible with the old coupling, so it is faster and more convenient to replace;
[0019] The weight of the new coupling is about 1 / 2 of the original coupling, the cost is lower, and it is safer to install after heating, without the risk of the coupling rolling down and hitting the ground. Secondly, the service life is about twice as long as the original one. The coupling range where teeth are often broken is about No. 28 in front of the machine to No. 42 in the back of the machine, with 70 rollers. The cost of one coupling is about 2,000 yuan, so replacing the new coupling can save 140,000 yuan. Due to the reduction in material and the replacement of heating speed, each replacement of the coupling can save about 20 minutes, that is, the replacement can save 1,400 minutes of work, about 24 hours.
[0020] Remove the bolt 5 with the M10 tapped hole, heat the half coupling A1 to 198℃ and install it on the roller shaft head, move the integrated flange 2 to the end of the half coupling B3, then heat the half coupling B3 to 198℃ and install it on the motor end. After cooling, apply dry oil on the integrated flange 2, use the sealing gasket 4 to form a seal, then position and align it with the half coupling A1 through the straight mouth, connect and tighten it with the bolt 5 with the M10 tapped hole, and complete the installation, which is more convenient to use. The thickness of both sides of the half coupling A1 and the half coupling B3 is reduced by 23mm per circle, which can reduce the weight while ensuring that the strength of use will not be affected, meeting the requirements of on-site use.
