Abstract
The utility model discloses a convenient-to-dismount sliding bearing of a synchronizing shaft for an LF cover in the field of auxiliary equipment for steelmaking, and aims to solve the problem that the replacement for exiting sliding bearings of synchronizing shafts consumes time and labor. The sliding bearing comprises an annular bearing bush; a flange plate is connected to the outer end face of the annular bearing bush, and is fixed on the lateral side of a support through a bolt; and the annular bearing bush and the flange plate are divided into two halves along the axial center line. With adoption of the sliding bearing, other parts of the synchronizing shaft are not needed to dismount when the sliding bearing of the synchronizing shaft is replaced, only the bolt connected with the flange plate is dismounted and the sliding bearing is pulled out through the flange plate, therefore fast replacement can be achieved, the operation time is reduced from original 10 hours to 2 hours, and the labor intensity is lowered.
Description
Technical field
The utility model relates to a kind of easy-to-dismount LF stove bell synchronizing shaft sliding surface bearing in steel-making utility appliance field.
Background technology
Refining techniques is one of gordian technique of modern STEELMAKING PRODUCTION, and wherein LF electric furnace and VD vacuum oven play converter steelmaking and the indispensable effect of continuous casting working procedure of connecting as the common equipment of refining treatment.Enter when processing the position at ladle, the bell of LF stove or VD stove falls, and forms the Working environment of refined molten steel, handle molten steel after, furnace cover lifting migrates out ladle.Bell keeps level by synchronizing shaft in the process of lifting, the Main Function of sliding surface bearing is lubricated synchronizing shaft, can make bell stable working, reliable, noiseless in lifting process.The sliding surface bearing of synchronizing shaft can wear and tear after work for some time, affects the balance of bell.If the dismounting sliding surface bearing then needs to pull down first synchronizing shaft middle sleeve, pin, sprocket shaft, then just can remove sliding surface bearing, changing sliding surface bearing needs about 10 hours, and the time is long, and labour intensity is large.
Summary of the invention
The purpose of this utility model is to overcome the prior art defective, and a kind of easy-to-dismount LF stove bell synchronizing shaft sliding surface bearing is provided.
The technical solution of the utility model is achieved in that a kind of easy-to-dismount LF stove bell synchronizing shaft sliding surface bearing, comprises annular bearing shell, and it is, is connected with ring flange in the outer face of annular bearing shell, by bolt ring flange is fixed on the bearing side.
Preferably, described annular bearing shell and ring flange vertically the medullary ray subdivision be 2 half.
Adopt the utility model structure, when changing the synchronizing shaft sliding surface bearing, can dismantle other parts of synchronizing shaft, only need dismounting ring flange joint bolt, directly sliding surface bearing is pulled out by ring flange, can realize quick-replaceable, the activity duration reduced to 2 hours by original 10 hours, had reduced labour intensity.
Description of drawings
Fig. 1 is the utility model structure and assembling synoptic diagram.
Among the figure, the 1-synchronizing shaft; The 2-sleeve; The 3-pin; The 4-sprocket shaft; 5-annular bearing shell; The 6-ring flange; The 7-bolt; The 8-bearing.
Embodiment
Be further described below in conjunction with accompanying drawing:
As shown in Figure 1, sliding surface bearing originally is annular bearing shell 5 structures, and the dismounting sliding surface bearing need to be pulled down first sleeve 2, pin 3, the sprocket shaft 4 in the middle of the synchronizing shaft 1, then just can remove sliding surface bearing, changing sliding surface bearing needs about 10 hours, and the time is long, and labour intensity is large.
Adopt the utility model structure, be connected with ring flange 6 in the outer face of annular bearing shell 5, by bolt 7 ring flange 6 is fixed on bearing 8 sides, annular bearing shell 5 be the copper structure of integral type with ring flange 6, and vertically the medullary ray subdivision be about 2 half.When changing the synchronizing shaft sliding surface bearing, can dismantle other parts of synchronizing shaft 1, only need make first not bringing onto load of synchronizing shaft 1 structure, dismantle again the joint bolt 7 of ring flange 6, directly 2 half sliding surface bearing are pulled out respectively by ring flange 6, installation process therewith step is opposite, can realize quick-replaceable, reduce the activity duration, reduced labour intensity.
The utility model provides a kind of sliding bearing structure form that can easy disassembling, assembling and replacing, also applicable to the sliding surface bearing of other all types of synchronizing shafts.
