Background technique
During no-dig technique and rotary digging foundation pile construction, if encountering the harder lithosphere of quality it is necessary to use dress
There is the construction drilling tool of rock bit, traditional gear wheel engineering drilling tool is to borrow after oil field tricone bit is rived to be welded, oil
Using being different from the use environment and engineering of field rock bit, oil drilling most importantly brill is deep bigger,
Reach thousands of or even several kms, and the construction depth of engineering drill is shallowly to several meters, it is only tens meters most deep, and oil field rock bit
The oil storage system of itself is deep to brill certain requirement, because needing drilling fluid in drilling process, and the bigger generation of depth
Pressure it is also bigger, so that the bearing for pushing oil storage system to rotate for rock bit provides lubrication, and in engineering using because
Deep limitation is bored, so that pressure is insufficient, prevent oil storage system is from playing a role.In addition nearest 2 years, no-dig technique and rotation are aimed at
The birth of the novel gear wheel of digging and design, it is contemplated that do not have effect, even more eliminate this oil storage system.In view of sliding axle
It holds in the case where no subsequent compensation lubrication, it is easy to it damages, it is a kind of from pressure compensation lube system therefore, it is necessary to design
System is to solve the above problems.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of rotary digging cone bit bearings
From pressure compensation lubricating system, solve the problem of that cone bit bearing position does not have subsequent compensation lubrication to be easy premature breakdown.
To achieve the above object, the utility model provides the following technical solutions:
A kind of rotary digging cone bit bearing from pressure compensation lubricating system, including gear claw body, circlip, spring, piston
And sealing ring, oil storage space is offered in the gear claw body, and spring, spring one end connection circlip, bullet are installed in oil storage space
The spring other end connects piston, and grease, grease and bearing in the oil storage space of pistons front sides are equipped in the oil storage space of pistons front sides
In grease connection.
Further, the circlip is fastened in the card slot of oil storage space.
Further, sealing ring is arranged on the piston.
Further, the gear claw body front end is equipped with gear wheel, and gear claw body passes through the teeth palm bearing divided into and gear wheel is matched,
Teeth palm bearing is uniaxial bearing, and teeth palm bearing lower end is provided with oil-through-hole.
Further, grease is opened up by teeth palm bearing lower end in the oil storage space of the pistons front sides oil-through-hole and bearing
In grease connection.
Further, the gear wheel of the gear claw body front end installation is compound tapered gear wheel, and gear wheel is in composite conic, in each conical surface
On be installed with cutting tooth.
In conclusion the utility model has the advantages that compared with prior art
Solution rotary digging cone bit bearing is aimed at the utility model discloses one kind to realize providing pressure without the external world
From the scheme of pressure compensation lubricating oil, to solve the problems, such as that the bearing lubrication bad service life is short；By outputing oil storage in gear claw body
Space passes through the compression thrust of spring in this space, pushes the piston for having sealing ring, and piston is pushed further into grease entrance
The position of bearings to be lubricated, when the grease in bearing does not consume, piston is in equilbrium position, once Bearing inner grease has
It is consumed, bearing position and oil storage space can generate pressure difference, and it is that axis is opened and holds a make-up oil that spring, which just will push piston,；This reality
It is skillfully constructed with novel, it is rationally distributed, bearing wearability is improved from force feed, service life is extended, enhances product
Cost performance.
For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair
The utility model is described in detail.
Detailed description of the invention
Fig. 1 is the sectional structure chart from pressure compensation lubricating system of the utility model.
Appended drawing reference: 1- gear claw body, 2- circlip, 3- spring, 4- piston, 5- sealing ring, 6- grease.
Specific embodiment
The technical solution of the utility model is described further in the following with reference to the drawings and specific embodiments.
Referring to Fig. 1, a kind of rotary digging cone bit bearing from pressure compensation lubricating system, including gear claw body 1, circlip 2,
Spring 3, piston 4 and sealing ring 5,1 front end of gear claw body are equipped with gear wheel, and gear claw body 1 passes through the teeth palm bearing and tooth divided into
It takes turns matched, it is preferred that in the present embodiment, teeth palm bearing is uniaxial bearing, and teeth palm bearing lower end is provided with oil-through-hole, the tooth
Oil storage space is offered in corpus unguis 1, spring 3,3 one end connection circlip 2 of spring are installed in oil storage space, and circlip 2 is fastened on storage
In the card slot in oily space, 3 other end of spring connects piston 4, and sealing ring 5, the oil storage space of 4 front side of piston are arranged on piston 4
