Abstract
The utility model relates to a bolt washer combination structure used for transmitting torque with a coating, which is particularly applicable to the connection between two parts for transmitting the torque. The combination structure includes a bolt, a spherical washer and an internal spherical washer and is characterized in that: the head of the bolt is provided with the spherical washer and the internal spherical washer, and the inner bores of the two washers maintain a clearance with the bolt; and the surface of the bolt and the spherical surfaces of the two washers are respectively coated with MoS2 dry film lubricant coatings. The bolt washer combination structure has simple and reasonable structure and the head of the bolt can freely move when bearing flexural oscillation, thus eliminating the additional flexural moment added on the head of the bolt in the use process of equipment. The combination structure can effectively prolong the service life of the bolt, thus improving the use reliability of connected equipment.
Description
Technical field
The utility model relates to a kind of torsion pass bolt washer composite structure of band coating, specifically is applicable to the connection between two parts of transmitting torque.
Background technique
In prior art, the head end of torsion pass bolt directly contacts with connected piece, in bearing torque and the equipment using process during additional bending moment, easily in the bolt head fracture, has reduced the operational safety of connected piece at work.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide the bending moment that is attached to bolt head in the using process of a kind of energy abatement apparatus, can improve the load situation of bolt, can improve the working life of bolt effectively, thereby improve the torsion pass bolt washer composite structure of the band coating of connected equipment operational safety.
According to the technological scheme that the utility model provides, comprise bolt, spherical washer, inner ball surface packing ring.Feature is: the head at bolt is provided with spherical washer and inner ball surface packing ring, and the endoporus and the bolt of described spherical washer and inner ball surface packing ring are gapped.
The sphere of described bolt surface and spherical washer and inner ball surface packing ring scribbles MoS2 dry lubricant coating respectively.
Compared with the prior art the utility model has the following advantages:
1, the utility model is simple and reasonable, and bolt head can be free movable when bearing flexural oscillations, thereby eliminate the addition bend moment that is added in bolt head in the equipment using process.
2, can improve the working life of bolt effectively, thereby improve the operational safety of connected equipment.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1: comprise bolt 1, spherical washer 2, inner ball surface packing ring 3.
The utility model is for eliminating the addition bend moment that is added in bolt 1 head in the equipment using process, adopted the spherical pair packing ring, promptly the head at bolt 1 is provided with spherical washer 2 and inner ball surface packing ring 3, and the sphere at bolt 1 surface and packing ring scribbles MoS2 dry lubricant coating, wherein spherical washer 2, the endoporus of inner ball surface packing ring 3 and bolt 1 have certain clearance, when bolt 1 head when bearing flexural oscillations, spherical washer 2 and inner ball surface packing ring 3 contacted spheres can slide relative, thereby eliminate the addition bend moment that in the equipment using process, is added in bolt 1 head, help improving the load situation of bolt 1, can improve working life.Comparative trial shows that this composite structure form has improved the working life of bolt 1 effectively, makes the torsion pass of equipment connect more reliable.
