Description

Technical Field

[0001] This utility model relates to a visual end cover for the reducer of a converter tilting mechanism, belonging to the technical field of steelmaking equipment in the metallurgical industry. Background Technology

[0002] The tilting mechanism reducer is a key component of the converter equipment, playing a crucial role in matching speeds and transmitting torque between the main rotating shaft of the support ring and the reducer. The tilting mechanism of the converter utilizes gear transmission enclosed within a rigid housing. The reducer includes: reducer bearings, bearing housings, several gears, an oil spraying device, and other parts. A braking device is located at the bottom of the suspended reducer. When the two gears of the suspended reducer rotate, the tangential force acting on the small gear by the larger gear is balanced through this device. The end cover, a major component of the reducer, supports the rotor assembly. Through the fit between the stop and the bearing, the rotor assembly is mounted within the stator assembly and operates stably and reliably. Simultaneously, specific values ​​for the air gap and axial clearance between the stator and rotor are required. Therefore, the end cover is one of the key components ensuring the coaxiality, air gap uniformity, and axial clearance between the stator and rotor.

[0003] Gear reducer end caps come in many structures and types, including disc-shaped, bowl-shaped, square, prismatic, and triangular. The end cap structure varies significantly depending on the motor's ventilation and protection requirements. For motors requiring cooling airflow, the end cap has ventilation holes of various shapes; some motors require good sealing, necessitating a closed end cap. The materials used for end caps also differ, with common choices including cast aluminum alloy, steel plate, stamped aluminum plate, iron plate (low carbon steel plate), and molded plastic. Cast aluminum alloy or aluminum alloy profile end caps are the most widely applicable due to their lightweight and moderate strength, suitable for various motor types. Gear reducers in converter tilting equipment require well-sealed end caps with sufficient material strength due to the operating environment; currently, gear reducers in converter tilting mechanisms all use steel plate.

[0004] When the components in the gear reducer are running normally for a certain period of time, it is necessary to inspect the running components. This requires disassembling the end cover and inspecting the wear condition of the internal parts. This can only be done when the converter is stopped, which affects the normal production of the converter. Utility Model Content

[0005] The purpose of this utility model is to provide a visual end cover for the reducer of the converter tilting mechanism, which can complete equipment inspection during the online operation of the reducer, clearly observe the wear and lubrication of the bearings, bearing seats and other accessories inside the reducer, and solve the problems existing in the background technology.

[0006] The technical solution of the utility model is:

[0007] A visual end cover for a converter tilting mechanism reducer includes a support cover, a transparent plate, bolts, a fixing plate, and a viewing hole. The support cover is fixed to the housing of the reducer and has a viewing hole. The fixing plate and the transparent plate are fixed to the support cover by multiple bolts, and the transparent plate is located between the fixing plate and the support cover.

[0008] The fixing plate has a ring-shaped structure, with its inner diameter matching the viewing hole on the support cover and its outer diameter being the same size as the transparent plate.

[0009] A gasket is provided between the transparent plate and the support cover.

[0010] A pressure ring is provided between the fixed plate and the transparent plate.

[0011] The fixed plate and the transparent plate are fixed to the support cover by eight bolts, which are evenly arranged along the circumference of the fixed plate and the transparent plate.

[0012] The beneficial effects of this utility model are: it can complete equipment inspection during the online operation of the reducer, and clearly observe the wear and lubrication of the bearings, bearing seats and other accessories inside the reducer. Attached Figure Description
