Abstract

The utility model in particular relates to a universal revolving gear of an epilithic retreading machine. An axle seat is fixedly arranged at the lower part of a gear case of a frame, and is sleeved on a planetary rotating shaft, a notch is processed on the axle shaft, and a floatation ball mechanism, an upper circular arc tray and a planetary plate are sleeved at the bottom of the planetary rotating shaft in sequence from the top to the bottom. The floatation ball mechanism comprises an inner ring, a floatation ball, a retainer, and an outer ring. A drop pit movably positioning the floatation ball is arranged on the inner side of the inner ring, the inner ring is fixedly arranged on the planetary rotating shaft, the outer ring is fixedly arranged on the planetary plate and is connected with a drive gear set through a bearing, a permanent seat is fixedly arranged at the upper part of the outer ring, a free gap is arranged between the permanent seat and the planetary rotating shaft, a lower circular arc tray matching with the upper circular arc tray is arranged on the planetary plate, and a blocking piece matching with the notch on the axle seat is arranged above the permanent seat. After the technical proposal is adopted, the whole planetary plate can perform the proper floatation according to the floor condition, so the sanding resistance is effectively reduced, and the abrasion of a wheel head is lowered.

Description

The universal rotation mechanism of stone surface retreading machine

Technical field:

The utility model relates to the decorative engineering technical field, refers in particular to a kind of universal rotation mechanism of stone surface retreading machine.

Background technology:

At present increasing ground surface finishing all adopts the stone floor, must carry out sanding and polishing to the floor when finishing handles, purpose is to make the floor smooth bright and clean, this operation generally all adopts stone surface retreading machine to carry out the floor polishing, and its planetary plate of stone surface retreading machine commonly used all is that rotate on the plane, when running into rough floor, only meeting hard grind, and can not produce unsteadyly, this can increase the polishing resistance, quickens the wearing and tearing of bistrique.

Summary of the invention:

The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, a kind of universal rotation mechanism of stone surface retreading machine to be provided.

For achieving the above object, the technical scheme that the utility model provides is: the universal rotation mechanism of stone surface retreading machine, include the planet rotating shaft, planetary plate, place driving gear set and frame gear-box in the planetary plate, bottom at the frame gear-box is fixed with axle bed, this axle bed is placed in the planet rotating shaft, connect by bearing between them, on axle bed, be processed with otch, the suit float ball mechanism successively from top to bottom in the bottom of planet rotating shaft, last circular arc pallet and planetary plate, this float ball mechanism includes inner ring, float ball, retainer and outer ring, on the inner ring sidewall, be provided with the pit of placing for the float ball activity, inner ring is installed in the planet rotating shaft, the outer ring be installed on the planetary plate and with driving gear set between be connected by bearing, top in the outer ring is fixed with holder, be provided with the free gap between this holder and the planet rotating shaft, on planetary plate, be provided with the following circular arc pallet that cooperates with last circular arc pallet, be provided with the block piece that cooperates with otch on the axle bed above the holder.

After adopting the technical program, whole planetary plate can carry out suitable floating according to the situation on floor, effectively reduces the polishing resistance, reduces the wearing and tearing of bistrique.
