Description

Side roller wheel of cooling bed straightening grid

Technical Field

The utility model relates to a side roller of cold bed straightening bars belongs to cold bed straightening bars technical field.

Background

In the steel rolling process, the bar is high-temperature red steel, and needs to be straightened by a cooling bed straightening grid so as to prevent the high-temperature red steel from being bent. Before the high-temperature red steel is fed into a cooling bed straightening grid, the high-temperature red steel slides forwards by leaning against the side surface of the straightening grid under the driving of a ground roller, and the high-temperature red steel can be automatically turned onto the straightening grid through a skirt board after reaching a certain length. And the side surface of the straightening grid is provided with a side roller which is used for preventing the surface of the red steel from being scratched due to the friction between the high-temperature red steel and the side surface of the straightening grid.

Because the straightening bar side roller wheel works at a high temperature all the time, once the lubrication condition is poor, the red steel surface and the straightening bar side roller wheel are scratched due to the blocking of the bearing.

As shown in figures 1 and 2, a bearing seat in a side roller of a straightening grid is a cylindrical through hole at present, a roller shaft is arranged in the bearing seat, and a bearing is installed in the bearing seat and then fixed at the bottom of the bearing seat through a bearing gland, so that the bearing fixing of the side roller is realized. This bearing frame produces the gap because of bearing gland in the below, between bearing frame and the bearing gland, because the straightening bars side running roller is at high temperature district work, no matter add thin oil or drier oil in the bearing frame, finally all can be leaked through the gap by high temperature melting back to lead to the bearing in the bearing frame to lack the lubrication and the card is died under high temperature.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a side running roller of cold bed straightening bars is provided to above-mentioned prior art, avoids the lubricating oil in the bearing frame to reveal, guarantees that the bearing has good lubricated operating mode, prevents that the red steel of high temperature from taking place the friction with straightening bars side.

The utility model provides a technical scheme that above-mentioned problem adopted does: a side roller of a cooling bed straightening grid comprises a bearing seat, a roller shaft and a conical bearing, wherein the roller shaft is fixedly provided with the bearing, the upper end of the bearing seat is provided with a shaft hole for inserting the end part of the roller shaft, an annular gap is formed between the shaft hole and the outer wall of the roller shaft, and the annular gap is used for storing lubricating oil; the roller bearing is characterized in that a limiting step is arranged in the shaft hole, the limiting step has a limiting effect on the bearing, a gland is fixedly arranged at the upper end of the bearing seat and is used for fixedly sealing the end part of the roller shaft in the bearing seat, and a roller sleeve is arranged on the roller shaft exposed out of the bearing seat.

The bearing is a conical bearing, and the conical bearing is fixedly connected with the roller shaft through a shaft stop.

The number of the conical bearings is 2.

Compared with the prior art, the utility model has the advantages of: the utility model provides a side running roller of cold bed straightening bars, become the bearing frame that the shaft hole was seted up to the upper end with through-hole type bearing frame, the roller shaft tip that will be fixed with conical bearing inserts in the bearing frame, the shaft hole upper end is sealed through the gland, the gland passes through bolt and bearing frame fixed connection, make lubricating oil seal in the bearing frame, the problem of lubricating oil leakage under the high temperature has been solved, guaranteed that the bearing has good lubricated operating mode in the bearing frame, avoid straightening bars side running roller card dead and the production of the red steel surface scotch of high temperature that leads to.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 3 and 4, the side roller of the cooling bed straightening bar in this embodiment includes a bearing seat 4, a roller shaft 1 and conical bearings 2, wherein 2 conical bearings 2 are respectively fixedly disposed at end portions of the roller shaft 1 through shaft stoppers 3, a shaft hole is formed at an upper end of the bearing seat 4, and the end portion of the roller shaft 1 sleeved with the 2 conical bearings 2 is inserted into the shaft hole, so that the roller shaft 1 can rotate in the bearing seat 4. An annular gap 7 is formed between the shaft hole and the outer wall of the roller shaft 1, and the annular gap 7 is used for storing lubricating oil for lubricating the conical bearing 2. The forming has spacing step in the shaft hole, and spacing step plays limiting displacement to conical bearing 2 for leave the gap between 1 bottom of roller axle and the shaft hole bottom, the lubricating oil in the annular clearance 7 flows to in the gap, plays lubricating displacement to conical bearing 2. The upper end of the bearing seat 4 is provided with the gland 5, the gland 5 is fixedly connected with the bearing seat 4 through the bolt, the end part of the roller shaft 1 is sealed in the bearing seat 4, and the leakage of lubricating oil is avoided. A roller sleeve 6 is arranged on the roller shaft 1 exposed out of the bearing block 4.

The end part of the roller shaft 1 fixed with the conical bearing 2 is inserted into the bearing seat 4, the upper end of the shaft hole is sealed by the gland 5, the gland 5 is fixedly connected with the bearing seat 4 by a bolt, so that lubricating oil is sealed in the bearing seat 4, the problem of lubricating oil leakage at high temperature is solved, the good lubricating condition of the bearing in the bearing seat 4 is ensured, and the generation of high-temperature red steel surface scratch caused by the dead roller block at the side of the straightening grid is avoided.

In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
