Description
Technical field
The utility model relates to transmission line hardware connection areas, in particular to a kind of wear-resistant U-shaped link attachment device.
Background technique
U-shaped link is forged with round steel, and purposes is wider, can be used alone, can also two uses in tandem.When two
A U-shaped link is in tandem in use, since transmission line of electricity is by wind action, drives fitting (U-shaped link) rotation, makes two U-shapeds
The phase mutual friction of link contact site makes the reduction of its service life by U-shaped link can after a certain period of time worn.
Contacting with each other as line contact, Chinese patent " transmission line of electricity wear-resisting type U-shaped link (CN between traditional U-shaped link
206135357 U) " a kind of mill type U-shaped link is disclosed, wear-resistant sleeve is installed by the segmental arc in U-shaped link, reduces two
It rubs between U-shaped link.However the method fails to reduce the contact area between two U-shaped links, the mode of the loss of friction
It is still contact slide friction, the contact portion between two U-shaped links can still generate biggish loss.
Therefore, it is necessary to design a kind of wear-resistant U-shaped link attachment device to reduce the friction between two U-shaped links.
Summary of the invention
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of wear-resistant U-shaped link attachment device, pass through by
Two U-shaped link contact portions replace traditional sliding friction by rolling friction, substantially reduce the abrasion of U-shaped link connecting portion
Rate extends the service life of U-shaped link.
The utility model is in order to solve the above technical problems, used technical solution is: a kind of wear-resistant U-shaped link connection
Device, including the first U-shaped link and the second U-shaped link, the first U-shaped link include the first U-shaped button and the first attachment base, the 2nd U
Shape link includes the second U-shaped button and the second attachment base, in the first U-shaped button and the first attachment base, the second U-shaped button and the second attachment base
Junction be equipped with slope surface, the junction of the first U-shaped link and the second U-shaped link be equipped with rolling bearing, axis of rolling bearing sleeve
It is located on the first U-shaped link.
Preferably, the inner ring of rolling bearing is connect with the first U-shaped button, is connected on the inside of the outer ring of rolling bearing and the second U-shaped button
It connects.
Preferably, the internal diameter of rolling bearing is identical as the first U-shaped button cross-sectional diameter.
The utility model has the beneficial effects that the utility model by by two U-shaped link contact portions by rolling friction generation
For traditional sliding friction, the rate of depreciation of U-shaped link connecting portion is substantially reduced, extends the service life of U-shaped link.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of wear-resistant U-shaped link attachment device；
In figure, the first U-shaped link 1, the first U-shaped button 1.1, the first attachment base 1.2, the second U-shaped link 2, the second U-shaped button
2.1, the second attachment base 2.2, rolling bearing 3.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of wear-resistant U-shaped link attachment device, including the first U-shaped link 1 and the second U-shaped link 2, the
One U-shaped link 1 includes the first U-shaped button 1.1 and the first attachment base 1.2, and the second U-shaped link 2 includes the second U-shaped button 2.1 and second
Attachment base 2.2, it is equal in the junction of the first U-shaped button 1.1 and the first attachment base 1.2, the second U-shaped button 2.1 and the second attachment base 2.2
Equipped with slope surface, it is such setting so that the first U-shaped link 1 and the second U-shaped link 2 during installation, the first attachment base 1.2 and second
Nut on attachment base 2.2 is more convenient to be turned.
It is equipped with rolling bearing 3 in the junction of the first U-shaped link 1 and the second U-shaped link 2, rolling bearing 3 is set in first
On U-shaped link 1.
Preferably, the inner ring of rolling bearing 3 is connect with the first U-shaped button 1.1, the outer ring of rolling bearing 3 and the second U-shaped button
2.1 inside connections.Sliding friction between first U-shaped link 1 and the second U-shaped link 2 is converted to the axis of rolling by such be arranged
The rolling friction for holding 3 greatly reduces the rate of depreciation of connecting portion, extends the service life of U-shaped link.
Preferably, the internal diameter of rolling bearing 3 is identical as 1.1 cross-sectional diameter of the first U-shaped button.Such setting is so that roll
The connection of bearing 3 and the first U-shaped link 1 is more firm.
The present embodiment working principle is as follows: since transmission line of electricity is by wind action, driving the first U-shaped link 1 and the 2nd U
Shape link 2 rotates, and the first U-shaped link 1 and 2 contact portion of the second U-shaped link are rotated by rolling bearing 3, and traditional
Sliding friction is compared, and frictional dissipation greatly reduces, and is reduced the rate of depreciation of U-shaped link connecting portion, is extended making for U-shaped link
With the service life, it is ensured that transmission line safety stable operation.
The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model
System, the features in the embodiments and the embodiments of the present application in the absence of conflict, can mutual any combination.This is practical new
The protection scope of type should be with the technical solution of claim record, technical characteristic in the technical solution recorded including claim
Equivalents are protection scope.Equivalent replacement i.e. within this range is improved, also the protection scope of the utility model it
It is interior.
