Abstract

The utility model relates to a rust removing machine with a novel main shaft component, and is composed of a working hammer head, a main shaft component, a flexible shaft and a motor mounted on a moving vehicle. The main shaft is supported in a main shaft casing by a radial bearing on the front end and a radial spherical bearing on the back end. Because of the main shaft bearing form adopted by the utility model, local pyrexia can be avoided, the work of the rust removing machine can be more reliable, and the service life of the rust removing machine can be prolonged. The utility model has the advantages of simple structure, easy fabrication, low technological requirement and low cost.

Description

Stain removing machine with new type spindle parts

The utility model relates to a kind of equipment of removing corrosion of metal, especially a kind of rust remover with novel spindle unit.

Rust remover has a revolving work tup, the main shaft of tup by being attached thereto, flexible axle obtains the power of motor, because tup directly is connected with main shaft, what tup applied to main shaft is local radial power, and main shaft is again to be connected with flexible axle to accept the power transmit, so spindle unit becomes the key of rust remover operate as normal, general spindle unit is made up of the block bearing at overcoat, main shaft and main shaft two ends.Block bearing has the forward and backward combination that is radial bearing; Or precedingly being spherical bearing entad, the back is the combination of radial bearing.The former requires the outer higher axiality that is with, the processing cost height, and owing to the axle center of steady flexible axle of flexible axle transmission and main shaft is difficult to be consistent, radial bearing again can not automatic aligning, support position heating is serious after the institute, and the latter is then because the poor rigidity of the entad spherical bearing that front end is installed, and the heating of supporting position seriously before the vibration that tup work is produced and centrifugal force made, thereby two kinds the supporting compound modes all have shortcoming, reduced the service life of rust remover.

The purpose of this utility model is to propose a kind of rust remover product with novel supporting combination spindle unit, to overcome weak point of the prior art.

The purpose of this utility model is to realize like this.

Rust remover with novel spindle unit, by work tup 6, spindle unit, flexible axle 2 and motored locomotive 1 are formed, for its spindle unit, the bearing that is bearing between main shaft 4 and the spindle jacket is respectively: front end is a radial bearing 5, and the rear end is spherical bearing 3 entad.

That Fig. 1 provides is an embodiment of the present utility model.The front end radial bearing of main shaft, rear end are bearing in the inside of spindle jacket with spherical bearing entad.

The main shaft supporting form that the utility model adopted can be avoided local pyrexia, can make rust remover work more reliable, and the life-span prolongs, and it is simple in structure, is easy to make, and technological requirement is low, and production cost is reduced.

Claims (1)

1, a kind of rust remover with novel spindle unit is by work tup, spindle unit, flexible axle and motored locomotive are formed, the bearing that is bearing between main shaft and the spindle jacket that is characterised in that of the present utility model, front end is a radial bearing, the rear end is spherical bearing entad.
