VIBRATION ISOLATOR OF SPRING TYPE Russian patent published in 2018 - IPC F16F3/02 F16F9/30 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Vibration isolator is made in the form of a frame with parallel-connected elastic-damping elements. Frame is made in the form of two interconnected by horizontal strip angles. On the strip the textile machine support element is installed through the vibration damping gasket. Left elastic-damping element is made in the form of damper, which comprises a body in the form of cylinder with bottom, in which the piston is located. Piston is made in the form of cup with collars, between which the copper based sintered friction material is arranged. Conical spring rests against the piston lower surface, which turns are covered with polyurethane. Cavity between the piston and the body bottom is filled with friction material. In the cylinder internal cavity groove the locking ring is fixed. Right elastic-damping element is made in the form of flat springs located at the bottom and top of the mounting block consisting of three plates. One of the ends of the flat springs is fixed between the two plates. Other ends are connected by means of an annular bend with friction shoes. Shoes are made in the form of U-shaped racks, rigidly connected with the base of shoes. U-shaped columns are covered with a layer of friction material. Friction pads are attached to the base of the shoes.

EFFECT: enabling increase in the vibration isolation efficiency.
