Abstract
The invention relates to a helical spring device with functions of damping and silencing, and belongs to the field of vibration screening machinery. The helical spring device is capable of reducing operation noise of a metal helical spring and reducing amplitude of a vibration screen during starting and stopping. A rubber seat spring embedded with a metal framework is installed at each of two ends of the metal helical spring; the appearance of the rubber seat spring is composed of two step cylindrical surfaces, wherein the step head surface of the short cylindrical surface is contacted with the head surface of the metal helical spring; and the long cylindrical surface is inserted into a hole of the metal helical spring. When the helical spring device with the functions of the damping and the silencing is installed on the vibration screen, a gap a is axially reserved between the rubber seat springs at two ends of the metal helical spring; the gap a is within a range of 10-30mm according to vibration mass and amplitude of the vibration screen; and the helical spring device disclosed by the invention has the characteristics of being low in noise during working and capable of rapidly starting and stopping the vibration screen and is applied to various vibration screening machines.
Description
Technical field
The invention belongs to the vibration screening machinery field; The frictional noise that both ends of the surface take place when mainly relating to reduce the operation of vibratory sieve metal coil spring, and solve that vibratory sieve starts and the band damping of resonance amplitude problems of too and the spiral spring device of noise reduction when stopping.
Background technology
Damping means employing on the vibratory sieve is metal coil spring the most widely at present, because the good damping result of metal coil spring, and manufacturing is simple, cost is low.But simple metal coil spring has 2 deficiencies as the damping means of vibratory sieve: the one, and two end faces of metal coil spring are that grinding becomes; Being installed between screen box seat ear and the bearing of vibratory sieve is the rigidity contact, when vibratory sieve is worked, can produce the noise that is interrupted; Metal coil spring resonance amplitude when vibratory sieve starts and the stop excessive 5-7 of normal amplitude (be doubly) in addition, and can not stablize rapidly and shut down, cause the dynamic load of brace foundation excessive.
Summary of the invention
The purpose of this invention is to provide a kind of spiral spring device with damping and noise reduction, this spiral spring device can effectively reduce the frictional noise of metal coil spring when operation both ends of the surface, and can solve effectively that vibratory sieve starts and the excessive problem of resonance amplitude when shutting down.
The present invention realizes through following measure; A rubber marshall springs that studs with metallic framework respectively is installed at the two ends of metal coil spring; The profile of rubber marshall springs is made up of two ladder faces of cylinder; Wherein the ladder end face of Short Cylinder Surface contacts with the end face of metal coil spring, and oval cylinder is inserted in the hole of metal coil spring.When the spiral spring device of band damping and noise reduction is installed on the vibratory sieve, between the rubber marshall springs at metal coil spring two ends, axially leave slit a, slit a is 10-30mm according to the mass of vibration of vibratory sieve and the big or small span of amplitude.
The invention has the beneficial effects as follows, owing to be provided with the rubber marshall springs, avoided direct contact the between metal coil spring both ends of the surface and screen box seat ear or the bearing, reduced the noise when vibratory sieve is worked at the two ends of metal coil spring; In addition because the axial slits between two rubber marshall springs is less, be in the resonance region amplitude that starts or shut down when excessive at vibratory sieve, two rubber marshall springs contact with each other, the operation or the shutdown of stable vibration sieve rapidly, the whole serviceability of raising vibratory sieve.Noise is little when having work, and the characteristics that can make the vibratory sieve start rapidly and shut down are applicable on the various vibration screening machineries.
Description of drawings
Fig. 1 is a structural representation of the present invention, and 1 is metallic framework, the 2nd among the figure, and rubber marshall springs, the 3rd, metal coil spring, a are two axial slits between the rubber marshall springs.
The specific embodiment
Below in conjunction with description of drawings one embodiment of the present of invention; A rubber marshall springs 2 that studs with metallic framework 1 respectively is installed at the two ends of metal coil spring 3; The profile of rubber marshall springs 2 is made up of two ladder faces of cylinder; Wherein the ladder end face of Short Cylinder Surface contacts with the end face of metal coil spring 3, and oval cylinder is inserted in the hole of metal coil spring 3.When the spiral spring device of band damping and noise reduction is installed on the vibratory sieve, between the rubber marshall springs 2 at metal coil spring 3 two ends, axially leave slit a, slit a is made as 15mm according to the mass of vibration of vibratory sieve and the size of amplitude.
Claims (2)
