Abstract
The utility model discloses a kind of loading machine main reducing gear of drive axle oil sealing dustproof constructions, it includes locking nut, flange, dustproof cover, bolt, sealing cover, bearing block, bracket, spiral bevel gear, lower bearing, bearing spacer, upper bearing (metal) and oil sealing；The flange is locked on spiral bevel gear by locking nut；The spiral bevel gear is carried on bearing block by metal (upper, and the bearing spacer for adjusting gap is mounted among metal (upper, which is mounted on the mounting hole of bracket and develops upper surface；The oil sealing is mounted in the sealing cover of bearing block upper end, and dustproof cover is installed in the upper surface of sealing cover, and the step surface of the dustproof cover develops oil sealing upper surface；The dustproof cover, sealing cover and bearing block are bolted on bracket.The utility model have the characteristics that structure is simple, production is low with maintenance cost, using reliable convenient, solve the problems, such as that oil sealing is be easy to cause to wear oil leak in the prior art, improve the security reliability of drive axle.
Description
Technical field
The utility model relates to loading machine main reducing gear of drive axle, and in particular to loading machine main reducing gear of drive axle oil sealing is anti-
Dirt structure.
Background technique
Currently, loading machine main reducing gear of drive axle oil sealing dustproof construction generallys use and dustproof cover is welded on flange, work
During work, though the structure can prevent the foreign matters such as dust from entering the case where oil seal lip causes oil seal failure generation, exist with
Lower defect: first is that using welding structure, needing to stock up in advance, and material needs repeatedly transhipment, and flange oil sealing mounting surface is easily caused to knock
Touching causes oil sealing to wear oil leak；Second is that the structure dustproof cover and flange are movement revolving part at work, and oil sealing axially only has
One end limit easily causes oil sealing inclination or whole when the oil sealing installation site size of sealing cover goes on difference when assembling gas testing
It is mobile, until interference flange, causes oil sealing to wear oil leakage fault.
Summary of the invention
The purpose of the utility model is to overcome drawbacks described above, provide that a kind of structure is simple, production is low with maintenance cost, uses
Reliable convenient loading machine main reducing gear of drive axle oil sealing dustproof construction, solution be easy to cause oil sealing to wear oil leak in the prior art
The problem of, improve the security reliability of drive axle.
In order to achieve the above object, the utility model loading machine main reducing gear of drive axle oil sealing dustproof construction includes locking screw
Mother, flange, dustproof cover, bolt, sealing cover, bearing block, bracket, spiral bevel gear, lower bearing, bearing spacer, upper bearing (metal) and oil
Envelope；The flange is locked on spiral bevel gear by locking nut；The spiral bevel gear is carried on by upper bearing (metal) and lower bearing
On bearing block, the bearing spacer for adjusting gap is mounted among upper bearing (metal) and lower bearing, which is mounted on bracket
On mounting hole and develop upper surface；The oil sealing is mounted in the mounting hole of sealing cover, and sealing cover is mounted on the upper end of bearing block,
Dustproof cover is installed in the upper surface of sealing cover, and the step surface of the dustproof cover develops oil sealing upper surface；The dustproof cover, sealing cover and axis
Seat is held to be bolted on bracket.
Above-mentioned loading machine main reducing gear of drive axle oil sealing dustproof construction by the way that dustproof cover is directly installed on sealing cover,
And step surface is developed into oil sealing end face, have following technical characterstic and the utility model has the advantages that
1, the main reducing gear of drive axle oil sealing dustproof construction changes welding structure in the prior art, but uses assembly side
Formula, can obviously reduce flange transhipment number, substantially reduce flange oil sealing mounting surface collide with, the risk of oil leak.
2, the main reducing gear of drive axle oil sealing dustproof construction, dustproof cover are directly installed on sealing cover by bolt, simultaneously
Step surface can develop oil sealing end face, avoid causing oil sealing to be released by air pressure during assembling gas testing, lead to oil sealing inclination, move
It is dynamic, to reduce oil sealing abrasion oil leakage fault rate.
Detailed description of the invention
Fig. 1 is that the main section view of the utility model loading machine main reducing gear of drive axle oil sealing dustproof construction installation in systems is shown
It is intended to.
Appended drawing reference: locking nut 1, flange 2, dustproof cover 3, bolt 4, sealing cover 5, bearing block 6, bracket 7, screw conic tooth
Take turns 8, lower bearing 9, bearing spacer 10, upper bearing (metal) 11, oil sealing 12.
Specific embodiment
With reference to the accompanying drawings and detailed description to the dust-proof knot of the utility model loading machine main reducing gear of drive axle oil sealing
Structure is described in further detail.
The main reducing gear of drive axle oil sealing dustproof construction of the utility model loading machine shown in Fig. 1 include locking nut 1, flange 2,
Dustproof cover 3, bolt 4, sealing cover 5, bearing block 6, bracket 7, spiral bevel gear 8, lower bearing 9, bearing spacer 10,11 and of upper bearing (metal)
Oil sealing 12；The flange 2 is locked on spiral bevel gear 8 by locking nut 1；The spiral bevel gear 8 is by upper bearing (metal) 11 under
Bearing 9 is carried on bearing block 6, and the bearing spacer 10 for adjusting gap is mounted among upper bearing (metal) 11 and lower bearing 9, the axis
Seat 6 is held to be mounted on the mounting hole of bracket 7 and develop upper surface；The oil sealing 12 is mounted in the mounting hole of sealing cover 5, sealing
Lid 5 is mounted on the upper end of bearing block 6, and dustproof cover 3 is installed in the upper surface of sealing cover 5, and the step surface of the dustproof cover 3 develops oil sealing 12
Upper surface；The dustproof cover 3, sealing cover 5 and bearing block 6 are fixed on bracket 7 by bolt 4.
The dustproof cover 3 of above-mentioned main reducing gear of drive axle oil sealing dustproof construction is directly installed on sealing cover 5, eliminates welding
Process reduces the oil leak risk of colliding with of 2 inner oil seal mounting surface of flange, while dust-proof to reduce the transhipment number of flange 2
The step surface of lid 3 develops 12 upper surface of oil sealing, avoids and oil sealing 12 is caused to lead to oil by air pressure release during assembling gas testing
12 inclination of envelope and movement, so that reducing oil sealing 12 wears oil leakage fault rate, increase enterprise income.
