Technical Field
The utility model relates to a cavity hydraulic wrench's mechanism, in particular to cavity hydraulic wrench with prevent unbalance loading lubricating structure.
Background
The hollow hydraulic wrench is suitable for places with narrow space. The method is suitable for the fields of electric power (nuclear power, wind power, hydroelectric power and thermal power), ships, metallurgy, traffic, cement, building, aviation and the like.
In the traditional hollow hydraulic wrench, a transmission part of a working head generally consists of a left side plate, a right side plate and a ratchet wheel, when the hydraulic wrench works, the left side plate, the right side plate and the ratchet wheel are easy to bite and the like due to uneven stress, and the matching surface of the ratchet wheel can be cracked and scratched, so that the hydraulic wrench is damaged, and the service life of the wrench is further shortened; but also causes an unbalanced load condition of the hollow hydraulic wrench.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art's defect, provide a cavity hydraulic wrench with prevent unbalance loading lubricating structure.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model relates to a hollow hydraulic wrench with an anti-unbalance loading lubricating structure, which comprises a wrench body, wherein,
a ratchet wheel is arranged at one end side of the wrench body;
a first side plate and a second side plate are respectively arranged at the two end sides of the ratchet wheel, wherein,
the first side plate with be provided with protector between the avris of ratchet and the second curb plate with be provided with protector between the avris of ratchet.
As an optimized technical solution of the present invention, the protection device is a sliding bearing.
As an optimized technical scheme of the utility model, protector is copper slide bearing.
As a preferred technical solution of the present invention, the protector is clamped between the first side plate and the ratchet wheel;
the guard is clamped between the second side plate and the ratchet wheel.
The utility model discloses the beneficial effect who reaches is: the utility model greatly changes the unbalance loading condition of the hollow hydraulic wrench by arranging the protective device between the ratchet wheel and the side plate, improves the stress of the side plate and well plays a role in lubrication; the friction coefficient of the matching surface of the side plate and the ratchet wheel is reduced; effectively avoids the condition of gnawing and breaking of the matching surface of the ratchet wheel and greatly prolongs the service life of the wrench.

in the figure: 1. a wrench body; 101. a ratchet wheel; 2. a first side plate; 3. a second side plate; 4. a guard device.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Examples
As shown in fig. 1-4, the utility model provides a hollow hydraulic wrench with an anti-unbalance loading lubrication structure, which comprises a wrench body 1, wherein a ratchet 101 is installed at one end of the wrench body 1, and the ratchet 101 is used for realizing the use function of the wrench;
the first side plate 2 and the second side plate 3 are respectively installed on the two end sides of the ratchet 101, wherein the protection devices 4 are arranged between the side sides of the first side plate 2 and the ratchet 101 and between the side sides of the second side plate 3 and the ratchet 101, the protection devices 4 can play a role in protecting the side plates (the first side plate 2 and the second side plate 3), and friction coefficients between the side plates (the first side plate 2 and the second side plate 3) and the ratchet 101 are reduced.
Furthermore, the protective device 4 is a sliding bearing, specifically, the protective device 4 is a copper sliding bearing, and the copper has the advantages of good corrosion resistance and lubricity, low friction coefficient, gluing resistance and the like, so that the unbalance loading condition of the hollow hydraulic wrench is greatly changed, the stress of the side plate is improved, and the lubricating effect is well played; the friction coefficient of the matching surface of the side plate and the ratchet wheel is reduced; effectively avoids the condition of gnawing and breaking of the matching surface of the ratchet wheel and greatly prolongs the service life of the wrench.
The protective device 4 is clamped between the first side plate 2 and the ratchet 101, and the protective device 4 is clamped between the second side plate 3 and the ratchet 101, so as to provide better buffering and lubricating functions.
When in use, as the protective devices 4 (preferably copper sliding bearings in this embodiment) are arranged between the ratchet 101 and the first side plate 2 and the second side plate 3, the friction coefficient between the matching surfaces of the side plates (the first side plate 2 and the second side plate 3) and the ratchet 101 can be significantly reduced; effectively avoids the condition of gnawing and breaking of the matching surface of the ratchet wheel 101 and greatly prolongs the service life of the wrench.
The utility model greatly changes the unbalance loading condition of the hollow hydraulic wrench by arranging the protective device between the ratchet wheel and the side plate, improves the stress of the side plate (the first side plate 2 and the second side plate 3) and well plays a role in lubrication; the friction coefficient of the matching surfaces of the side plates (the first side plate 2 and the second side plate 3) and the ratchet wheel 101 is reduced; effectively avoids the condition of gnawing and breaking of the matching surface of the ratchet wheel 101 and greatly prolongs the service life of the wrench.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
