Abstract
The invention discloses a rapid cooling device for a furnace delivery roller bed bearing block on a hot-rolled strip steel production line with a wide cooling range and a good cooling effect. The rapid cooling device consists of a bearing block (1), a steel sleeve (2), a bearing end cover (3), an aligning roller bearing (4) and a water throwing ring (5), and is characterized in that: the bearing block of a furnace delivery roller bed and the bearing end cover are made into an integral structure, and an annular groove is formed inside the bearing block; and the steel sleeve is welded on the bearing block, the annular groove is sealed, a water inlet and a water outlet are drilled above or below the bearing block, and the bearing end cover is in bolted connection. A split structure of a bearing cover and the bearing block is transformed into the integral structure, a cooling system on the top of the bearing block is transformed to have a structure that the annular groove is formed inside the bearing block; and by the transformed inner structure, a cooling area of the bearing is greatly increased, the service life of the bearing is effectively prolonged, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of cooling unit, relate in particular to a kind of hot-rolled strip production line furnace delivery table bearing support quickly cooling device with good cooling performance.
Background technique
Existing hot-rolled strip production line furnace delivery table bearing block structure generally is that steel plate directly is welded on the bearing cap, and bearing support and bearing cap are made split, adopt the bolt to be connected with pin, and the bearing (ball) cover employing is embedded.Cooling system generally designs on the bearing cap; Therefore require when cast bearing covers, must its upper half part be cast as grooved, with the processing of bearing support top, again steel plate is welded on the end face then; Form sealing configuration like this; Creep into the mouth of a river and water outlet in the left and right sides of bearing cap, feed cooling water in use, reach cooling purpose.
There is the certain structure defective in above cooling system; Such as in use; Transmit medium container and be in the bearing upper end; This design limitation's cooling medium can only cool off upper half part of bearing fast, and lower half portion of bearing can not touch cooling medium so cooling effect is not good, so traditional design can not reach whole bearing is carried out cooling purpose.
Summary of the invention
The objective of the invention is to overcome the deficiency of said structure; Provide that a kind of cooling range is big, the hot-rolled strip production line furnace delivery table bearing support quickly cooling device of good cooling results; Form by bearing support (1), steel bushing (2), bearing (ball) cover (3), selfaligning roller bearing (4), slinger ring (5), it is characterized in that: the bearing support and the bearing (ball) cover of furnace delivery table are made of one the formula structure, at the inner open loop-shaped groove of bearing support; Then steel bushing is being welded on the bearing support; Circular groove is formed sealing, on bearing support with below creep into water and water outlet, bearing (ball) cover adopts the bolt jointing type.
Beneficial effect of the present invention is: transform the split-type structural of bearing cap and bearing support as integral structure; With bearing support top reformation of Cooling System is the inner open loop-shaped groove of bearing support structure; Change internal structure later; Increase the film-cooled heat of bearing greatly, effectively guaranteed the working life of bearing, improved manufacturing efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a partial structurtes schematic representation of the present invention;
Fig. 3 is the cooling structure partial enlarged drawing.
Embodiment
Like Fig. 1, shown in Figure 2, earlier sky in the bearing support and tank are processed, then steel bushing (2) is being welded on the bearing support (1), machining is being carried out to the steel bushing inner ring in the welding back, in order to avoid process the back welding deformation earlier.During assembling, earlier with the slinger ring hot charging on roller, and then bearing support (1) installed on the roll neck, again with selfaligning roller bearing (4) and roll neck and the assembling of steel bushing (2) inner ring, pack at last bearing shaft end ring and bearing (ball) cover (3).The present invention unites two into one original bearing support and bearing cap through the structure of bearing support; Saved bolt and locating stud, the benefit of bringing like this is: in use, water gets in the bearing support through water intake; Flow out from the outlet water from thereon mouth again after being full of whole tank; Make original part cool off the cooling that has become whole bearing, increased the cooling range of bearing, prolong the working life of bearing bearing.
Claims (1)
1. hot-rolled strip production line furnace delivery table bearing support quickly cooling device; Form by bearing support (1), steel bushing (2), bearing (ball) cover (3), selfaligning roller bearing (4), slinger ring (5); It is characterized in that: the bearing support (1) and the bearing (ball) cover (3) of furnace delivery table are made of one the formula structure; At the inner open loop-shaped groove of bearing support (1), then steel bushing (2) is being welded on the bearing support (1), circular groove is formed sealing; On bearing support (1) with below creep into water and water outlet, bearing (ball) cover (3) adopts the bolt jointing type.
