Abstract

The invention relates to mechanical engineering and is intended to protect products from vibration and shock. The aim of the invention is to increase the reliability of damping and control friction force. The execution of the bulges 3 of the collet 2 in the form of alternating conical and cylindrical sections interacting with the protrusions 4 makes it possible to regulate the force of friction of the collet against the rod 1. The larger the diameter of the cylindrical part of the thickening 3, the greater the elastic force of the spring sleeve 5, and therefore, the greater strength of training The presence of the slots 7, the nuts 8 and 9, and the lugs 6 allows the collet 2 to be moved relative to the stem 1 and fixed in the right place. The contact of the rubbing parts (collet and stem) occurs over a considerable surface, which increases the durability of the damper, reduces wear of the parts and increases reliability of operation. 1 il.

The invention relates to mechanical engineering and is intended to protect products from vibration and shock.

The purpose of the invention is to increase the reliability of damping and regulate the frictional force by performing the thickening of the petals of the collet in the form of alternating cylindrical and conical sections interacting with the protrusions of the spring sleeve.

The drawing shows a damper, a view of Yu from the side.

The damper contains a cylindrical brush 1, axially mounted on it a collet 2, the petals of which are made with thickenings 3, the surface of which is formed four times that, in order to increase the reliability of the damped conical and cylindrical and force control, co-operative parts interacting In the walls of the spring sleeve, there are protrusions 4 of the spring sleeve 5. There are stops 6 on the top-through grooves and on the outer surface of the collet; 6 stops are included, the threads are in the grooves 7 of the sleeve 5, on the outer surface ana alternating konicheskshii and NOSTA sleeve 5 is threaded at 20 and the cylindrical portions are threaded for interactions it nut 8 and with protrusions 9.deystvi springs conductive sleeve.

The damper works as follows. There are stops at the end of the collet; entrances 4 of the spring bushing 5 contact into the grooves; the damper is provided with two tights with thickenings 3 and pressed with nuts, screwed onto the thread, by the spring 2 to the rod 1 by elastic force. The stub bushing for contacting with this force can be adjusted by displacements.

the collet 2 along the axis of the damper in such a way that the protrusions 4 are in contact with the cylindrical portions of the thickening 3 of different diameters. Selecting the desired diameter and, consequently, the elastic force of the sleeve 5 with nuts 8 and 9 secure the collet 2 relative to the sleeve 5.
