Description

Iso-Reception refers to devices for applying tension to flexible elements, especially metal tape.

A coil for winding is known, consisting of a shell, on the outer surface of which longitudinal holes are made with a specified pitch, and a shaft with an emphasis and a pressing nut, (On the Kotor with the possibility of moving along the axle of the drum, there are mounted conical spring-loaded discs that interact with corresponding to the lining and surface of the shell.

One: for such a drum is complex in structure and has insufficient rigidity.

For the purpose of gaining the rigidity of the drum on the outer surface of the shell, they are made (not, these are additional longitudinal slits located with the same pinch as the main, right, this pinch of additional rifles is shifted relative to the Essential ones: by a given amount, and the length of each cut is Em 3 / 4- 4/5 LENGTH forming shells, and the inner conical discs are spring-loaded relative to the outer.

The drawing shows the proposed drum, a general view.

On the 1st shaft 7 ", conic disks 2-5 are deposited, ipacHHpaeiMbie is pairwise springs 6 and 7. Disks with their conical surfaces

abut against the conical surfaces of the spring shell 8, which has to provide for the spring. the deaf longitudinal slits 9 of alternating-opposite direction 3 / 4-4 / 5 dl in length forming the shell 8. On the ends of the wall 8. The disk 2 abuts against the shoulders: and: to the shaft /, the disk 3 - into the gland nut 10. Ulor L is the 10 n nut travel stop fixed on the shaft 1 rigidly.

The cylindrical nature of the drum with the largest diameter is achieved by its usual processing with the greatest release of the ring. In addition, the curvature of the conical surfaces of the sides of the shell. The curvature of the curvature at its greatest p.a vzhatii.

The device works as follows. When rotating and moving, the nuts 10 up the shaft / discs 2 and 3 come together (since the disk 2 is pressed into the protrusion of the shaft 1), acting through the springs. 6, 7 ina the disks 4, 5, also bringing them closer, orri. The 4, 5 l 2, 3 discs act conically on the same surface of the shell 8, stretch its sectors, and thus cut the diameter of the drum. When moving the jack 10 down, the disks 2 W. 5, 3 n 4 are consumed by the action of the springs 5 and 7, and the shell 8 decreases the IB diameter.

When the nut W is in contact with the stop

11 the diameter of the drum will become the smallest.

Subject invention

A winding drum, consisting of a shell, on the outer surface, which has the radial arresis with a given pitch: the shaft with an emphasis and a nut, and which, with the possibility of non-displacement along the axis of the drum, are fitted with cue spring-loaded discs, interacting with the corresponding surface. MI shells, characterized in that, in order to increase its rigidity, on the outer surface of the sheath, additional longitudinal slits were made, which were soldered to the same surface as the main ones; The distance is shifted relative to the Aon ion value, the given value, and the length of each slot is 3/4–4/5 lengths forming its shell, and the inner conical disks of the spring are relative to external ones.
