Abstract
The utility model discloses a shock absorbing spring of mechanics. The helical combined rubber spring is in internal and external helical shape; the internal helical shape is a metal helical spring, taking the function of supporting frame in the combined spring; the external helical shape is a rubber spring, taking the function of absorbing shock. The upper and the lower ends of the helical combined rubber spring are both provided with a metal piece to ensure the contact between the helical combined rubber spring and the plane of the support seat of the vibration machine. The combined spring has the characteristics that small movement, low noise and short shutting-down time are sent to the foundation; in addition, the combined spring has large free area, therefore, the working stress is small, the service life is long, and the capability is high; thus, the combined spring is particularly suitable to use on the large and medium vibration machine.
Description
The utility model is a kind of central spring of machinery that is used for, and is particularly useful for a kind of spiral rubber-spring complex of the central vibration damping of machinery.
Metal coil spring, rubber spring, pneumatic spring and straight tube rubber-spring complex etc. are arranged in the present mechanical vibration damping, require to pass to that the ground dynamic load is little, noise is little, dead time is short for the vibrating machine spring.And use maximum now is metal coil spring, and the dynamic load that this spring is passed to ground is big, noise big, rigidity and be deformed into linear relationship, so dead time is long, can cause unexpected stopping accident when spring fracture.So moreover because that spring is subjected to that materials limitations can not do is too big.Though rubber spring and straight-tube complex spring have the characteristics that the ground live load is little, noise is low, dead time is short of passing to.But this spring working stress is big, the life-span short, only can be applicable on the small vibrating machine and use.And pneumatic spring is poor because of horizontal rigidity, and often inflation, has also limited its development.The present invention has overcome the deficiency of above-mentioned spring shortcoming, and has designed a kind of spiral rubber-spring complex, and this spring has characteristics such as live load is little, noise is low, dead time is short, and working stress is little, and the life-span is long, and bearing capacity is big.
The purpose of this utility model provides a kind of a kind of spiral rubber-spring complex that uses on the big-and-middle-sized shaking machine that is applicable to.
The utility model is achieved in that as metal coil spring, bearing capacity is big, but is subjected to process limitation, and noise is big again; And rubber spring, good damping result, noise is little, but bearing capacity is little.In order to select the advantage of these two kinds of springs, give up its shortcoming and two combine into one with it, design the spiral rubber-spring complex.In order to reduce the working stress of complex spring, increase its free area, complex spring is designed to internal and external screw shape, spiral is a metal coil spring, it plays the support framework effect in complex spring; External spiral shape is a rubber spring, and it plays damping effect in complex spring.Have a metalwork in the every end circular trough in the two ends up and down of complex spring, its effect is to guarantee complex spring and the plane contact of vibrating support.It is low that thereby the formation of spiral rubber-spring complex obtains working stress, and bearing capacity is big, good damping result, the nonlinear complex spring that noise is little.
The utility model is compared with existing technology, and it is little to have the ground of passing to live load, and noise is low, the characteristics that dead time is short, and because free area is big, so working stress is little, the life-span is long, bearing capacity is big, is particularly suitable for the use on the big-and-middle-sized shaking machine.
Provide with accompanying drawing according to concrete structure and the embodiment that the utility model proposed below:
Fig. 1 is the general structure half sectional view of the spiral rubber-spring complex that proposes of the utility model.
The drawing explanation: (1) is metal coil spring, and (2) are rubber springs, and (3) are metalworks.
According to the described concrete structure of Fig. 1, below concrete structure of the present utility model and embodiment are elaborated.
See shown in Figure 1: the spiral rubber-spring complex is made of metal coil spring (1), rubber spring (2), metalwork (3).Metal coil spring (1) constitutes internal and external screw shape with rubber spring (2).Metal coil spring (1) adopts the high-quality spring steel to make, and it plays the support framework effect in complex spring.Metal coil spring (1) must carry out shot-peening, pickling processes, answers surface coating to improve the adhesion strength of rubber and metal coil spring before sulfuration.External spiral shape is rubber spring (2), and it occupies 2/3rds of metal composite spring global stiffness, and it is to lean against vulcanization of rubber shaping in the mould, and the synthetic cement of the natural gum more than 80 percent that adopts is made.Metalwork (3) is in the circular trough of the two ends of spiral rubber-spring complex, and its effect is a plane contact of guaranteeing complex spring and shaking machine bearing, touches face with rubber and contacts and should carry out pickling and coat Bond to guarantee the adhesion strength with rubber.Metalwork (3) must guarantee that both ends of the surface are parallel and vertical with the complex spring center line.
Claims (1)
1, a kind of central shock-absorbing spring of machinery that is used for wherein has pneumatic spring, rubber spring, and straight simple rubber spring and metal coil spring (1) is characterized in that the spiral rubber-spring complex:
A, metal coil spring (1) are in the spirality of rubber spring (2);
B, has metalwork (3) in the circular trough of two ends up and down at rubber spring (2).
