SU27595A1 - Brake for spindles of watering machines - Google Patents

Description

In the present invention, using a yoke covering one end of a spindle neck, equipped with a roller at the other end and having a rod equipped with a brake pad inside, with a head carrying another roller, means spindle two-sided braking, using a pedal and levers on the brakes mounted in the casing. the cam, which in mutually opposite directions pushes the clips and rod rollers, and by means of a coil spring, worn on the rod, it is proposed to release the spindle from braking neither

In FIG. 1 shows a longitudinal vertical section of the brake: FIG. 2 - its longitudinal horizontal section.

The brake consists of a casing / (figs. 1 and 2) in which the holder 2 is placed, the spindle neck covering the spindle of the brake pad J4 is placed at one end, and the supporting roller 5 is at the other end. The holder 2 in the middle part is fastened with a bar 8 simultaneously serving as a guide for a movable rod 3 provided with a brake pad 6, a guide bar 7 and a head 9 with a roller /. On

the rod 5 is fitted with a coil spring 4 which is compressed by the guide flaps 7 and 8 and serves to release the spindle from braking, and the braking itself, moreover, two-sided, is made by turning the cam JO sitting on the axis 73, as it is moving apart when rotating the rollers 5 and L simultaneously brings together the leather-covered brake pads 6 and f4, which press against the spindle neck located between them. The brake is attached by two bolts 72 to an iron bracket, and the latter is attached to the frame of the watering machine.

To stop the spindle, the worker steps on the pedal connected by levers with the cam 70, and the latter, turning on the axis 72, brakes the spindle. After stopping the pressure on the pedal, the cam assumes its previous position, and the spring screw with pressure on the strips 7 and 8 pushes the brake pads, releasing the spindle.

The subject matter of the invention.

 Brake for spindles of watering machines, characterized by the use of the spindle collar at one end

and the carrier 5 at the other end of the holder 2, inside of which is placed a rod 5 equipped with a brake pad 6 with a head P carrying a roller //, on which the rollers 5 and // to move the holder 2 and the rod B in opposite directions, two-sided braking of the spindle, the cam 10 acts, turning around the main shaft, fixed in the casing 7, with the help of levers when the foot is pressed on the pedal.

2. When applying the brake according to claim 1, in order to release the spindle from braking, the coil spring 4 is put on the rod 3 and rests at one end against the washer 7 moving together with the rod 3 and attached to the side walls 8 at the end 8 clips 2.
