Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting, drawing and straightening machines, in particular to an oil leakage prevention device for a reducer of a continuous casting, drawing and straightening machine. Background Art

[0002] The continuous casting straightening machine is a crucial core component of the bloom casting machine. Its primary functions are to pull the continuous casting billet from the crystallization vibrator, perform three-point straightening on the curved billet, and feed the dummy bar. These tasks require sufficient power and precise motion. The reducer within the straightening machine effectively transmits the motion and power provided by the motor to the straightening machine. However, due to excessively high ambient temperatures, the sealing ring began to age and deform, leading to lubricant leakage and severely impacting the reducer's performance.

[0003] In the related art, the input shaft of the reducer usually uses a lip seal, and its sealing performance cannot meet the requirements of long-term use of the reducer in a high-temperature environment. Usually, lubricating oil leakage begins to occur after one week. In order to ensure production, grease is used instead of lubricating oil to solve the problem of oil leakage; however, in a high-temperature environment, the grease will produce defects such as atomization, failure, and deterioration after being used in a high-temperature environment for a period of time, which will still affect the performance and service life of the reducer, resulting in the need to stop production to replace the seal and lubricating oil or grease, which will have an adverse effect on production efficiency. Utility Model Content

[0004] The purpose of the present utility model is to provide an oil leakage prevention device for a reducer of a continuous casting straightening machine, so as to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An oil leakage prevention device for a reducer of a continuous casting straightening machine, comprising:

[0007] A tensioning and straightening machine, wherein a reducer is provided at the bottom of the tensioning and straightening machine;

[0008] The reducer comprises a worm gear pair and worm threads, wherein the worm gear pair and the worm threads are meshed with each other;

[0009] The input end of the reducer is provided with a stationary ring, one side of the stationary ring is provided with a rotating ring, and one side of the rotating ring is provided with a push ring;

[0010] The ends of the stationary ring and the rotating ring are respectively provided with mechanical sealing rings;

[0011] A cooling device is provided at the bottom of the reducer.

[0012] The oil leakage prevention device for the reducer of the continuous casting straightening machine according to this solution has at least the following technical effects:

[0013] The oil leakage prevention device for the reducer of the continuous casting straightening machine is provided with mechanical sealing rings at the static ring end and the rotating ring end of the reducer input end respectively. Compared with the lip sealing ring provided at the traditional reducer end, the mechanical sealing ring can effectively enhance the sealing performance of the reducer input end, reduce the leakage of lubricating oil inside the reducer, greatly reduce the loss of lubricating oil, and improve the overall performance and service life of the reducer; at the same time, since the reducer is suspended, a cooling device is provided in the bottom space thereof, which can effectively prevent the lubricating oil or grease in the reducer from atomizing, failing, and deteriorating in a high temperature environment, thereby ensuring the use performance of the lubricating oil or grease, thereby improving the operating stability and reliability of the reducer, and ensuring the continuity and efficiency of the work.

[0014] As a further solution of the present invention: the mechanical sealing ring is a fluororubber sealing ring.

[0015] As a further solution of the present invention: the mechanical sealing ring is an "O"-shaped sealing ring.

[0016] Since the mechanical seal ring is made of fluororubber seal ring and the mechanical seal ring is an "O" type seal ring, its corrosion resistance, high temperature resistance and good sealing performance enable the mechanical seal ring to fit tightly with the stationary ring and rotating ring at the input end of the reducer, greatly enhancing the sealing effect, and can effectively prevent the leakage of lubricating oil at the input end of the reducer, ensuring the normal operation of the straightening machine reducer and the quality of continuous casting products.

[0017] As a further solution of the present invention: the worm gear pair includes a meshing inlet and a meshing outlet, the trimming length of the meshing inlet is Δψr=4mm, and the trimming value Δfr=0.25mm.

[0018] As a further solution of the present invention: the trimming length of the meshing outlet is Δψc=4 mm, and the trimming value is Δfc=0.17 mm.

[0019] Since the worm gear pair includes a meshing inlet and a meshing outlet, by trimming the meshing inlet and the meshing outlet of the worm gear pair, the trimming length of the meshing inlet is Δψr=4mm, the trimming value Δfr=0.25mm, the trimming length of the meshing outlet is Δψc=4mm, and the trimming value Δfc=0.17mm. Compared with before trimming, the impact and friction of the worm thread when entering or exiting the engagement can be effectively reduced, making it more stable, effectively improving the operation effect of the reducer, and increasing the transmission efficiency of the worm gear pair and the service life of the reducer.

[0020] As a further solution of the present invention: the cooling device includes a cooling water tank, and a water inlet is provided at one end of the cooling water tank, and a water outlet is provided at the other end.

[0021] Since the cooling device includes a cooling water tank, a water inlet is provided at one end of the cooling water tank and a water outlet is provided at the other end, the cooling device can form a cooling cycle, which can quickly take away the heat inside the reducer, greatly reducing the internal temperature of the reducer, preventing the reducer temperature from being too high, causing aging and deformation of the sealing ring, and leakage of lubricating oil, and can avoid the atomization, failure and deterioration of the lubricating oil caused by high temperature, thereby improving the overall performance of the reducer, reducing the downtime of the repaired equipment, and improving work efficiency.
