Description

Quick-dismantling type baffle plate door shaft bearing seat

Technical Field

The utility model belongs to the technical field of mechanical appurtenance, especially, relate to quick detach formula baffle door-hinge axle bearing.

Background

The middle shaft produced in the current market is connected with an electric actuating mechanism and a multi-shaft shutter type baffle door. Door spindle systems are basically divided into three types: the bearing and the shaft seal are not arranged, and the fixed shaft sleeve is rotationally connected; the bearing and the shaft seal are arranged, and the fixed bearing (built-in type) is rotationally connected; the device is provided with a bearing, a shaft seal, a fixed shaft sleeve (external type) which is rotationally connected, and a shaft sleeve type door shaft system, wherein the clearance between the shaft and the shaft sleeve is less than 0.10 mm. The shaft sleeve dust accumulation jamming and seizure faults are very easy to occur in the operation process. The door shaft system with the built-in bearing and the built-out bearing has high-temperature bearing jamming and opportunistic abrasion faults. The three modes have high-temperature ash deposition and jamming faults, cannot be overhauled on line, and have large overhauling workload and complex process.

Disclosure of Invention

In view of this, the utility model aims at providing a quick detach formula baffle door-hinge bearing frame aims at solving high temperature flue, shutter formula baffle door-hinge system, because of inconsistent and clearance design undersize of material coefficient of expansion, under the high-temperature dust medium condition, the axle supports transmission system with the direct suit of axle sleeve or bearing high temperature jamming etc. very easily takes place the defect of jam, the trouble of stinging.

In order to achieve the purpose, the technical scheme is as follows:

the quick-release type baffle door shaft bearing block comprises a supporting system and a bearing block mechanism, wherein the supporting system comprises a metal plate, a door shaft, a shaft seal and a shell, the metal plate is arranged at one side end of the shell and covers the end, the door shaft penetrates through the shell, one end of the door shaft penetrates through the metal plate, the shaft seal is arranged at the position where the door shaft penetrates through the metal plate, the other end of the door shaft penetrates through one side end face of the shell, which is far away from the metal plate, and the penetrating end, which is far away from the metal plate, of the door shaft penetrates through the shell is provided with the bearing mechanism; the bearing mechanism comprises a bearing, a bearing seat and a bearing end cover, the bearing seat is a split bearing seat, the bearing is arranged on the bearing seat, the bearing is arranged on a penetrating end of the door shaft penetrating through the shell and far away from the end face of one side of the metal plate, the bearing seat is arranged on the outer side wall of the shell, and the bearing end cover is arranged on the bearing seat.

Preferably, the bearing seat is fixed on the shell through a jackscrew.

Preferably, the bearing end cover is fixed on the bearing seat through bolts.

The utility model has the advantages that: the utility model discloses a shutter door shaft bearing takes place the bite because of high temperature and damages or the deposition is worn and torn seriously and is damaged, changes the maintenance on line, when having guaranteed unit safe operation, has reduced again and has overhauld safe risk, has improved maintenance efficiency.
