The invention relates to protection from vibration and can be used in any field of technology.

Known leaf bearing described in the book "Car: Basics design: Textbook for institutes of higher education "Automobiles and automobile economy"/Nju, Vchem, Annarbor and others - M.: mechanical engineering. 1986 - 304 S. (RES, s).

Leaf bearing described in the specified source, the package contains leaf springs forming the spring means spatial fixation in the form of through holes in the root portion of the spring with a corresponding pin and a fixing leaf springs from moving or rotating in the transverse plane of support, attachment fittings pack leaf springs leaf springs and the nodes securing the support to the object.

Significant disadvantages of the known supports are asymmetrical support, the inability to adjust the characteristics to achieve the required efficiency of protection from vibration and narrow scope.

The invention is directed to the improvement of leaf supports.

The technical result of the invention:

the ability to change the characteristics (rated load, natural frequency);

enable the use of the buffer changes packages springs (reduce or increase the Deposit);

effective protection of buildings against vibration and shock, as well as the expansion of the scope;

the reliability of the bearings and increase the lifetime of the object (due to the symmetry and the presence of multiple packages).

The above results are achieved due to the fact that:

1. Leaf bearing is made of at least two separate springs, diverging from the root - internal ends along the length of the angle from 0 to 180°.

2. Means for fixing the leaf springs and leaf springs generally made in the form of cuts glass with holes on its base under the pin and the slots on the cylindrical part for preferably a dense package location leaf springs with simultaneous transmission of the holes on the front - root portion of each leaf spring over the pin.

3. Attachment pack leaf springs leaf springs consists of two flanged bushings - inner threaded outer surface and outer with a threaded hole, and a non-through hole pins, compounds which together form a cylindrical body with an outer annular space to accommodate selective glass with root - inner ends of the springs with pins, one ends of which are mounted in the holes of the glass and the other in the through holes of the flange outer flange of the bushing and the final mounting of the leaf springs is uvorachivayas flanged bushings.

4. Bracket, support to vibroisolation object is a threaded hole provided in the inner flange of the sleeve.

5. The attachment of the working - outer part of the frame consists of two ring segments interconnected by transverse planes preferably spherical profile with the regulatory clearance to accommodate working - the outer part of the leaf springs. While working - the outer part of the springs is set in mounts directly or through non-metallic (rubber, composite) materials.

The drawing shows the top view and cross section of a leaf supports.

Bearing contains springs 1 at least two out of the pack leaf springs 2, the fixation device in the form of through holes In the root - internal parts With springs with the corresponding pin 3, means for fixing the leaf spring 2 and spring 1 generally in the form of cuts 4 cups with holes D on the basis of under the pin 3 and the radial grooves on the cylindrical part for preferably a dense package location leaf springs with 2 simultaneous transmission holes In the root - internal part of each leaf spring 2 via pin 3, attachment pack leaf springs 2, consisting of two flanged bushings - inner 5 with a threaded outer surface F and the outer 6 mesibov the m hole G, and blind holes I under the pins 3, the attachment of the working - outer part J to the frame, consisting of two rings 7, 8, connected by a fastening elements 9 transverse planes preferably spherical profile To regulatory clearance L for placing working - the outer part of the J springs 1. For securing the support to the Foundation ring 8 is made with holes M

Thanks to the support of several springs 1 worker - outer part J is installed in the attachment points 7, 8 or all free with a gap L>0, or no gap L<0, or part of a carriage 1 with a gap L>0, and the other part without a gap L<0.

In contrast to the known proposed leaf bearing has several packages of springs (in the drawing - 10 PCs), which increases the value of the free running (important feature) leaf supports.

In addition, due to the presence in the support of a sufficiently large number of sheets (for example in the drawing - 50 pieces), the support has a significant milesowego friction than the well-known support, so support can be installed on the object without hydraulic shock absorber.

These design features supports allow its use as a car suspension, and vibration-damping support of various objects, including plants with internal combustion engines (ice).

To sabatella energy from vibroisolating object on the Foundation is passed through a flanged bushing 5 leaf springs 2 springs 1 and the flange outer sleeve 6, that is, through the elastic connection. Therefore, the vibration is due to the settings of the oscillation of the leaf spring 2 spring 1 bearing on the frequency close to the frequency of dangerous oscillations, and incurred in connection with this paralyzing their reactive forces of inertia.

Thus, the reactive force of inertia is created by using elastic elements - leaf springs 2 springs 1, communicating with one hand through the sleeve 5 with the unit, and on the other through the sleeve 6 with the Foundation.

In addition to the elastic connection between the unit and Foundation support also provides frictional connection, which is due to the mutual displacement during deformation of the leaf springs 2, which leads to milesowego friction that dissipates vibrational energy, leading to a substantial reduction in the transmission of disturbing efforts on the Foundation.

Bearing, carrying out the elastic and frictional connection between the object and the Foundation is, therefore, a spring damper.

Leaf springs 2 springs in addition to steel can also be made of non-metallic materials, for example composite.

Included mounting node 7, 8 can be provided a rubber (or other elastic material) item buffer function or sound.

Thanks to these characteristics of the host leaf p is dinner 2 and the fastening support provides the ability to change the individual sheets 2 to the other prior to installation on the object without the use of additional parts or changes to existing, consequently, the support is adjustable as to their rated load and frequency of natural oscillations.

In addition, some of the springs 1 may be removed from the support without changing the design and use of additional parts, if, for example, for an object requires less rated load.

Empty - loose grooves E do not affect the reliability of the fastening spring 1 support.

These features enhance the possibility of applying one-size supports for multiple objects that differ in weight, and hence the scope of its application.

The novelty of the invention are revealed from the comparison with the prototype, and is as follows:

bearing is made of at least two separate leaf springs 1, diverging from the root - internal ends along the length of the angle from 0 to 180°;

means for fixing the leaf spring 2 and spring 1 generally made in the form of cuts 4 cups with holes D on the basis of under the pin 3 and the slots E in the cylindrical part for preferably a dense package location 1 leaf springs with 2 simultaneous transmission holes In the root - internal parts With each leaf spring 2 via pin 3;

the mount package 1 leaf springs 2 springs consists of two flanged bushings - inner 5 with a threaded outer surface G and externally is 6 with the screw hole F, and blind holes I under the pins 3, the connection of which together form a cylindrical body with an outer annular space to accommodate selective glass 4 with root - inner ends of the springs 1 with pins 3, one ends of which are mounted in the holes D of the base of the Cup 4, and the other in blind holes of the first flange of the outer sleeve 6 and the final mounting of the leaf springs 1 manufacturer of flanged bushings 5, 6;

bracket, support to vibroisolation object is a threaded hole provided in the inner flange of the sleeve 5;

working - the outer part J of the leaf springs 1 are made or straight, or with ears, and thanks to the support of several springs 1 worker - outer part J is installed in the attachment points 7, 8, 9, or free with a gap L>0 or a part of the springs with a gap L>0, and the other part without a gap L=0.

Thus, the invention conforms to the criterion "novelty".

Any other support with the above advantages, features and distinctive characteristics are not known.

Currently being developed drawings for fabrication support. After manufacturing support planned testing on existing known methods.
