Description
Technical field
The present invention is the divisional application of patent application " hinging mechanism for working device ", the Application No. of the patent application
201410551997X, the applying date is on October 17th, 2014.The present invention relates to technical field of engineering machinery, especially a kind of work
Make device linkwork.
Background technology
Connection between engineering machinery equipment typically using the connection of sliding bearing linkwork, generally, linkwork by
Axle, axle sleeve or bearing shell, dust ring are constituted, and are lubricated by lubricating grease.And engineering machinery operating mode is severe, service load point
Cloth is uneven, easily causes axle local pressure, and it is poor to add lubrication Membranous lipid fluidity, causes partial lubrication uneven, works long hours
Easily cause the wear out failure of axle and hole.
Swing arm and dipper chi typically have the fit-up gap of 2-4mm or so, adjust dress during assembling by plastics adjusting pad
With gap, dust ring is housed at side clearance, and due to dust ring non-rigid, axial float is big once in a while for dipper, dust or gravelstone
Head grain can slave arm or dipper side enter axle and axle sleeve, easily cause axle abrasive wear failure；The linkwork of such structure is adopted
It is lubricated with lubricating grease, the filling time interval of lubricating grease is generally 50-100 hours, when severe in cement or sposh etc.
When being worked in environment, the time interval of grease up is shortened to 8 hours, i.e. driver must fill lubrication before start daily
Grease lubrication, very trouble.
The content of the invention
The present invention provides a kind of hinging mechanism for working device, and it can solve the hinge of the equipment of existing engineering machinery
The problem of connection mechanism dust-proof effect difference.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：Include bearing shell, be installed on the bearing shell
Interior axle and dust ring, it is set with bushing outward with the bearing shell, and the axle two ends are respectively sleeved on left floating sealing base and right floating sealing base,
The face that the bushing is in contact with the left floating sealing base is provided with the first float grease seal chamber, and the bushing connects with the right floating sealing base
Tactile face is provided with the second float grease seal chamber, and the first float grease seal chamber connects with the second float grease seal chamber with the axle；
Each described float grease seal chamber is built with a pair of float grease seals；The inner face of the left and right floating sealing base is floating respectively at described first
Dynamic oil sealing chamber and the second float grease seal chamber are externally provided with pit, and the pit is inlayed with the termination of the bushing, and it inlays gap
It is a clearance channel for complications.
In above-mentioned technical proposal, more specifically scheme can also be：Each described float grease seal is by float grease seal ring and close
Seal is constituted, and two float grease seals are disposed side by side in the float grease seal chamber, the floating oil of float grease seal described in each pair
The side of seal ring abuts against.
Further：The float grease seal ring is made up of high-hardness metal material, the float grease seal ring and the sealing ring
The face being in contact is inclined to set.
Due to using above-mentioned technical proposal, the present invention compared with prior art, to have the advantages that：
1st, due to the paired float grease seal for being attached separately to be arranged on floating sealing base inner face and bushing of the float grease seal of equipment
In chamber, formed static sealing, when these float grease seals contact with each other rotation when again formation end face dynamic sealing, small particle be difficult into
Enter axle and shaft room, dust-proof effect is very good, therefore, it can reduce adhesive wear and the abrasive wear of bearing, improve sliding axle
Hold the reliability of mechanism's work.
2nd, because the design of float grease seal chamber is on bushing and floating sealing base the two smaller parts, processing cost is reduced.
3rd, due to being designed with a plurality of oil duct and oilhole on bushing, and design fluted on bushing, form shoe cream room,
Increase oil reserve, and lubricating oil is gathered near oilhole, strengthen the circulation of whole oil duct, improve lubricating efficiency.
4th, due to being provided with an oil duct on the surface of axle, the oil filler point of equipment is made to be connected with float grease seal chamber, and this
Oil duct can make in the gap of more lubricating oil immersion axles and bearing shell, be conducive to the lubrication between axle and bearing shell.
5th, because the inner face of floating sealing base is externally provided with pit in float grease seal chamber, the pit is inlayed with the termination of bushing, its
It is a clearance channel for complications to inlay gap, and this gap passage constitutes a dustproof construction, and the dustproof construction is ensureing work
In the case of making the normal fit-up gap of device, it is to avoid extraneous solid soil, solid particle are directly entered float grease seal position
Put, the effective influence for reducing environment to floating sealing ring extends the service life of floating sealing ring.
6th, floating seal maintenance period is up to 3000-5000 hours, greatly delays maintenance period, reduces labor
Dynamic time cost.
