Abstract

The utility model discloses an embossing taper spring washer for preventing a bolt from loosing. The embossing taper spring washer for preventing a bolt from loosing is in a cone shape. The surface forms of the embossing taper spring washer for preventing a bolt from loosing can be divided into inner surface embossing, outer surface embossing, inner surface and outer surface embossing, and a smooth surface. The embossing taper spring washer for preventing a bolt from loosing of the utility model is installed between a bolt and a connected member, and the axial force of the primary shape and the patterns on an inner taper surface and an outer taper surface are restored by the embossing taper spring washer for preventing a bolt from loosing. The friction force between threads, and the friction force among the embossing taper spring washer for preventing a bolt from loosing, the bolt, and the connected member are augmented, and thereby, the loosening of the bolt is effectively prevented. The utility model has simple structure, convenient use, and easy manufacture. The embossing taper spring washer for preventing a bolt from loosing has the advantages that the embossing taper spring washer for preventing a bolt from loosing bears large and uniform force in the process of loosening prevention, and the embossing taper spring washer for preventing a bolt from loosing can bear vibration loads.

Description

Emboss taper spring washer

A kind of embossing conical spring washer that prevents bolt looseness.

Scyewed joint is in the removable very widely connection of industrial application.The reliability of scyewed joint is to prevent that screw thread from getting loose in using, and existing scyewed joint anti-loose method generally adopts spring washer, plain washer or to jacking nut, deficiency arranged all in actual applications.1, spring washer: easily, very unreliable because elastic force inequality and elastic force are little along the opening direction cracking, and easy damaged contact supporting surface, the flexural stress of increase bolt.2, plain washer: itself does not possess anti-loose ability.3, to jacking nut: nut quantity doubles, and weight is big, the position that takes up space is bigger, and is less economical and to tighten dismounting all inconvenient.

The purpose of the utility model design: the axial pressure when utilizing conical spring washer to be subjected to bolt or nut screwing clamping makes the axial force that produces the shape that resiles after the gasket deforms, and this masterpiece is used between bolt and coupled the screw thread, thereby prevents that it from becoming flexible.

Structural design of the present utility model: conical spring washer adopts steel plate to process, Section Design coning, rigidity is bigger.In the course of the work, along with bolt screw the axial pressure-bearing of packing ring, the tapered cross-section is out of shape gradually, until being pressed into a plane, and produces the axial force that packing ring is resiled.Between the screw thread of this power effect bolt and coupling, increase the frictional force between the screw thread, thereby played locking effect.The utility model adopts the light face on washer face; Or at (1), the internal surface of conical spring washer; (2), outer surface; (3), inner and outer surface all is processed with various decorative patterns, increased the friction factor between the packing ring supporting surface, therefore increased the frictional force when preventing bolt looseness.

The good effect of characteristics of the present utility model and generation:

1, simple in structure; Easy to use; Manufacture easily;

2, utilize the section deformation of conical spring washer to produce the frictional force that the decorative pattern on the conical surface up and down of axial force that packing ring resiles and conical spring washer produces with surface of contact and obtain good anti-loosing effect;

3, have the stressed big and stressed characteristics that evenly also can bear oscillating load in locking process.

Description of drawings:

Fig. 1, the embossing of embossing conical spring washer inner conical surface;

Fig. 2, the embossing of embossing conical spring washer outer cone surface;

Fig. 3, the equal embossing of the inside and outside conical surface of embossing conical spring washer;

Fig. 4, embossing conical spring washer light face;

Wherein: 1 is washer inner surface; 2 is bead outer surface;

Most preferred embodiment:

The embossing conical spring washer, its surface can be divided into: 1, internal surface embossing, 2, outer surface embossing, 3, the equal embossing of inner and outer surface; 4, light face.In the equipment installation process, the embossing conical spring washer is enclosed within on the bolt, the position that diameter is big contacts with supporting surface, bolt is screwed on the connection screw until packing ring is flattened, or screw-down torque is tightened in accordance with regulations, this moment, packing ring produced an axial force that resiles between the screw thread that acts on bolt and coupled, frictional force between the screw thread is increased, again because the inner and outer surface of embossing conical spring washer all is processed with decorative pattern, therefore also increased the frictional force of the inner and outer surface of the packing ring that prevents bolt looseness, the stack of two power has prevented the loosening of bolt effectively.

Claims

A kind of embossing conical spring washer that prevents bolt looseness is characterized in that: process with steel plate, longitudinal plane is taper shape, the washer face form can be divided into:

(1) inner conical surface embossing;
(2) outer cone surface embossing;
(3) the equal embossing of inside and outside conical surface;
(4) light face;

The embossing form is: can increase the friction factor of washer face, increase the various points or the line decorative pattern of the frictional force between packing ring and bolt and coupled.
