Description
Technical Field
The utility model relates to a chill roll technical field in the rollout table, in particular to bearing frame internal seal device of chill roll in the rollout table.
Background
The run-out table is used for conveying the steel plate to the high-speed flying shear inlet guide ruler by the finishing mill, the total length is 43500mm, 137 run-out tables are arranged from the finishing outlet to the high-speed flying shear inlet guide ruler, and the fixed guard plate is arranged on the run-out tables. The cooling of the roller table must be considered because the temperature of the strip steel transported by the roller table during operation is high. The cooling mode of the roller way can be divided into an inner cooling roller and an outer cooling roller. The outer cold roll is provided with a cooling water collecting pipe, the water of the inner cold roll is provided by a rotary joint, and the number of the inner cold rolls is 18. The internal cooling roller is mainly installed below an instrument measuring instrument and used for ensuring that the measuring instrument is not influenced by cooling water and the phenomenon of inaccurate measurement of the steel plate occurs.
Along with the operation of the inner-cooling roller in a high-temperature environment for a long time, the sealing between cooling water and lubricating oil in the bearing seat of the inner-cooling roller is damaged, so that the bearing seat is filled with water, the lubricating oil of the bearing seat of the inner-cooling roller is diluted by the water and washed away, the bearing of the inner-cooling roller is damaged, the phenomenon that the roller does not rotate is caused, and the surface quality of a steel plate is seriously influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing a bearing frame internal seal device of cold roll in rollout table, concrete technical scheme is as follows:
a sealing device in a bearing seat of a cold roll in an output roller way comprises a bearing seat, a rotary joint and a connecting sleeve;
the connecting sleeve is provided with a mounting seat;
the coupling sleeve is integrally arranged at one end of the bearing seat;
the mounting seat of the connecting sleeve is fixed with the rotary joint through a bolt;
the front end of the mounting seat at the root of the connecting sleeve is provided with a circular boss;
the boss is provided with a sealing groove, and the O-shaped sealing ring is arranged in the sealing groove;
the bearing is arranged in the bearing seat, the head part of the bearing is contacted with the connecting sleeve, and a sealing gasket is arranged at the contact part;
through the O-shaped sealing ring, the connecting sleeve and the bearing head are sealed, and a sealing waterproof layer is added.
A bearing frame internal seal device of interior chill roll of rollgang, its characterized in that: the length of the coupling sleeve is 121.5 mm;
the working principle of the sealing device in the bearing seat of the cold roll in the run-out table is as follows: the inner cold roll is cooled, namely cooling water enters the inner cold roll through a rotary joint, enters the interior of the roll through a connecting sleeve and a water pipe and flows out of the hollow part of the connecting sleeve, as shown in figure 2; the original design is that there is a sealed pad between coupling sleeve and the bearing frame gland, and the effect is for preventing the bearing frame from intaking, but because interior cold roll surface temperature is high, sealed pad receives the influence of high temperature for a long time, makes its water seal effect not good, and the roll table bearing frame often intakes, causes the bearing to damage, and the roll table trouble influences production and product quality. The connecting sleeve is lengthened by improving the connecting sleeve, as shown in figure 4, a boss and a sealing groove are processed near the root part of the connecting sleeve, and an O-shaped sealing ring is installed. Through O type circle, with sealed between adapter sleeve and the spindle nose, increase one waterproof, but in the unable bearing frame that enters into the roll table of water makes, guarantee the life of bearing, and then ensure roll table normal operating.
The utility model has the advantages that: the technical scheme of the utility model make simply, easily realize, change the system to the coupling cover between internal cold roll rotary joint and the water pipe, increase one waterproof sealing, the utility model discloses can carry out effectual solution with the interior cold roll bearing housing condition of intaking, guarantee the normal operating of interior cold roll table. After improvement, the product quality is greatly improved, and considerable economic benefits are created for enterprises every year.

Detailed Description
As shown in fig. 1-4, the sealing device inside the bearing seat of the cold roll in the run-out table is characterized in that: the bearing seat 1, the rotary joint 2 and the connecting sleeve 3;
the connecting sleeve 3 is provided with a mounting seat 4;
the coupling sleeve 3 is integrally arranged at one end of the bearing seat 1;
the mounting seat 4 of the connecting sleeve 3 is fixed with the rotary joint 2 through a bolt;
the front end of the mounting seat 1 at the root of the connecting sleeve 3 is provided with an annular boss 5;
the boss is provided with a sealing groove, and the O-shaped sealing ring is arranged in the sealing groove;
