Abstract

Polishing machine, which is characterized by being made up of a cast iron base, inside which the motor is mounted with the pulley, which drives the machine. The pulley transmits the movement by means of a trapezoidal belt to the pulley, both pulleys have three steps in order to obtain three working speeds. The pulley sets the main shaft in movement, mounted on two double row bearings housed in the base, these two bearings are fixed axially by means of two covers, these two covers have a lateral channel on which it penetrates with a slight slack, in one side the flange of the pulley, and on the other the flange of the ring, which is fixed by means of a screw to the main shaft. These channels and tabs serve to preserve the bearings from dust filtration, produced by the work of the machine. In the right extremity of the main shaft, the two plates are mounted, which fasten to the motor pulley, by means of a nut. On the largest protrusion of the base, the piece is mounted, and fastened to the base by means of two screws, this piece is the support of the tube and the band tensioning mechanism, it has a hole through which it goes up, down and rotate the tube. The piece is mounted on the piece. The piece is fixed on number two by means of the handle, threaded and with a pivot on the end of the thread that is housed in the channel of the piece outlined with number two. Tightening it, it fixes in the desired position the piece and in turn the guide-pulley. By loosening the handle, with a small manual impulse, the piece can be turned as required, three on piece two. The piece in the upper part has the housing of the dust boot bellows fastened in the upper part to the part that is screwed to the pipe. The dust boot bellows preserves dust from the tube and the zipper. In the upper part of the tube, the support is fixed, which in turn fixes the position to the axis. The guide pulley is mounted on the shaft on two bearings fixed by two covers that have two flanges to protect the bearings from dust. To eliminate the axial clearance between the two bearings is a bushing, all of which is fixed by a screw. The tensioning mechanism is mounted on the piece, and consists of a zipper that is screwed to the tube, the rack engages with the pinion-shaft, which rotates on the lid. The pinion shaft carries on the other end a ratchet in whose channels the nail enters. The pinion shaft rests on one side on the lid and on the other on the piece. The piece rotates on the three and in order that it does not come out it carries a screw, whose end enters the channel of the clamp. On the piece goes the shaft, on whose ends are the nail and a bakelite handle. The shaft is guided by the piece and tensioned by means of a spring. The operation of the model, polishing machine, is carried out in the following way, by operating the switch the motor is started, which transmits the movement to the axis. On the pulley, the polishing band is placed, linking the band with the guide pulley. The band works on the drive pulley. (Machine-translation by Google Translate, not legally binding)
