The loose roll is provided with a roll body which is axially provided with a through hole, annular grooves which sink inwards in the radial direction are arranged on the roll body, and a bearing pedestal is arranged on each annular groove. In the utility model, the roll body adopts an integral structure, so that the loose roll can be manufactured through once forging, therefore, the axial precision of the loose roll can be kept with no need for adjustment, and the manufacture process is very convenient.
Description
Technical field
The utility model relates to a kind of free roller that is installed in the continuous casting machine fan-shaped segment position.
Background technology
Because the free roller on the continuous casting machine fan-shaped segment is longer relatively; Quality is bigger, and it is directly installed on the below of crystallizer, with the crystallizer close together; So when rolled plate; Free roller not only can receive the steel billet extruding of big quality, also directly contacts with the very high steel billet of temperature simultaneously, causes free roller receiving very easily damage under the extruding of high temperature erosion and gravity.Prior art is in order to solve the load-bearing problem; Free roller adopts three section rollers and the roll shaft that is installed in the section roller usually; And between adjacent two section rollers, bearing block is installed; Simultaneously between free roller and roll shaft, adopt square key to be connected so that both can secure fit to realize synchronous rotation; In order to solve, be provided with the passage that is used for the cooling water circulation in the central region of roll shaft, to protect the free roller of conticaster through water-cooled mode by the high temperature billet steel erosion problem.
In view of the structure of free roller; Because of roll shaft is directly to drive its rotation by power set, and roll shaft transmits through square key the active force that free roller applied, so; Require square key should have certain intensity, otherwise can free axis integral body scrapped because of square key damages; Simultaneously, because of free roller is to be made up of three section rollers, when making free roller; Need process three section rollers and roll shaft earlier, and then on section roller and roll shaft, mill out the rectangle keyway, so; The free roller manufacturing process relative complex of this kind structure; Cost of manufacture is higher, and in assembling process, the coaxial precision of three section rollers of adjustment is also difficult; In addition, the bearing block at free roller middle part breaks down when needing to change, and at first will end axis bearing and section roller be disassembled from roll shaft; Behind replacing or the maintenance bearing block, also to whole free roller be sent into the specific occasion and debug its complicated operating process; Required time is longer; Labour intensity is bigger, and can influence the rolling of steel plate, increases production cost.Though the passage that above-mentioned roll shaft middle part is provided with can guarantee that cooling water can continuous flow; But because of adjacent two rollers two can not reach desirable synchronization extent in power transmission; When initiative roll shaft rotated, small relative displacement took place in instantaneous meeting between driven roll shaft and the initiative roll shaft, after roll shaft moves a period of time; Roll shaft can or receive the effect of twisting resistance to make not reach between the roll shaft because of wearing and tearing to closely cooperate; Cause in the roll shaft cooling water flow out of, and meeting splash everywhere after the water outflow is prone to make bearing to damage because of receiving water erosion.
Summary of the invention
The purpose of the utility model provides a kind of free roller that utilizes the mode that changes the roller self structure to solve the continuous casting machine fan-shaped segment position of problems such as maintenance and service life.
The free roller at the continuous casting machine fan-shaped segment position that the utility model proposed has a roll body that axially is provided with through hole, and this roll body is provided with the cannelure that radially caves inward, and on each cannelure, bearing block is installed.
Said cannelure comprises the end axis bearing that is arranged on the roll body two ends and is arranged on the section bearing block on the roll body.Said section bearing block is made up of the split-type shaft bearing, and said end axis bearing is made up of solid housing.
Said solid housing has a main component, and main component is provided with the axially extending bore that the bearing outside diameter on internal diameter and the roll body is complementary, and on main component, also is provided with the passage that is used for the cooling water circulation.
Said split-type shaft bearing has one and goes up main component and following main component, on last main component and following main component, is provided with semi-circular recesses, and on last main component and following main component, is respectively arranged with the passage that is used for the cooling water circulation that is interconnected.
In the free roller at the continuous casting machine fan-shaped segment position that the utility model proposed, roll body adopts whole structure, when making roll body; Only need once to forge and just can process the free roller of this kind; So, the free roller of this kind need not adjust just can retainer shaft to precision, and manufacturing process is very convenient; Simultaneously; As long as the connector that will go up between main component and the following main component because of the split-type shaft bearing just takes off and can it be unloaded from roll body; This mode for convenience detach is convenient to maintenance or is changed bearing block very much, and the principal element that free roller breaks down to be bearing block go wrong, so; The free roller of this kind is long service life not only, and keeps in repair very convenient; In addition, because of roll body is an integral body, the cooling-water duct in the roll body can not go wrong, and can further prolong its service life.
