Abstract
A kind of door machine walking mechanism reduction gearbox output shaft leakage-resistant device, is related to high pedestal jib crane maintenance device technical field, especially belongs to a kind of leakage-resistant device of door machine walking mechanism reduction gearbox output shaft.For the dish-type end cap that bottom is recessed, it is characterized in that, the back cover including sealing, the annulus being linked together with back cover；The annular ring peripheral surface is equipped with and the former consistent unthreaded hole of reduction gearbox output shaft end cap hole location.The leakage-resistant device is fastened on reduction gearbox output shaft outer end by the utility model, it is therefore prevented that dust and the grains of sand enter in output shaft and oil sealing gap, reduce the heel and toe wear of output shaft, reduce oil leakage phenomenon, have prevented security risk.
Description
Technical field
The utility model relates to high pedestal jib crane maintenance device technical fields, especially belong to a kind of door machine walking mechanism
The leakage-resistant device of reduction gearbox output shaft.
Background technique
High pedestal jib crane is widely used in the places such as harbour, open-air depots, door as a kind of jib-type crane tool
Machine walking reduction gearbox is limited by box volume, as shown in figure 3, existing output shaft end side is dust-proof using the oil sealing and PVC matched
Lid combination, the mounting means of additional output shaft end cap.Since door machine walking reduction gearbox installation site is lower, ore in sand form, dust infringement
Most serious, tiny ore in sand form, dust tend to enter output shaft by the bad PVC dustproof cover of sealing effect and oil sealing is matched
At the gap of conjunction, as the rotation of output shaft in turn results in the abrasion of oil sealing and output shaft, reduction gearbox is caused to export again and again
The case where axis permeability, oil leak, causes the waste of gear oil, and the gear oil leaked out when oil leak is serious can cover whole door machine vehicle table
Severe compromise is caused in face.
Summary of the invention
The purpose of this utility model seeks to provide a kind of door machine walking mechanism reduction gearbox output shaft leakage-resistant device, to reach
To the abrasion reduced between output shaft and oil sealing, reduction gearbox output shaft oil leakage phenomenon is reduced, the purpose of security risk is prevented.
The door machine walking mechanism reduction gearbox output shaft leakage-resistant device of the utility model is the recessed dish-type end cap in bottom,
It is characterized in that the back cover including sealing, the annulus being linked together with back cover；The annular ring peripheral surface is equipped with slows down with original
The consistent unthreaded hole in case output shaft end cap bore position.
The door machine walking mechanism reduction gearbox output shaft leakage-resistant device, can using sheet metal cold stamping punching and
At.
The door machine walking mechanism reduction gearbox output shaft leakage-resistant device of the utility model, removes former reduction gearbox output shaft end
Lid, by door machine reduction gearbox output shaft and oil sealing integral sealing, using consistent several with hole location on former reduction gearbox output shaft end cap
The leakage-resistant device is fastened on reduction gearbox output shaft outer end by unthreaded hole, it is therefore prevented that dust and the grains of sand enter output shaft and oil sealing seam
In gap, reduces the heel and toe wear of output shaft, reduce oil leakage phenomenon, prevented security risk.
Detailed description of the invention
Fig. 1 is the schematic front view of the utility model door machine walking mechanism reduction gearbox output shaft leakage-resistant device；
Fig. 2 is the left schematic cross-sectional view of the utility model door machine walking mechanism reduction gearbox output shaft leakage-resistant device；
Fig. 3 is the assembly schematic front view of the utility model original door machine reduction gearbox output shaft.
Specific embodiment
As depicted in figs. 1 and 2, the utility model door machine walking mechanism reduction gearbox output shaft leakage-resistant device is a bottom
Recessed dish-type end cap, the end cap include the back cover 1 of sealing, the annulus 2 being linked together with back cover 1.The annulus 2 is circumferentially
Surface be equipped with the consistent unthreaded hole of former 3 hole location of reduction gearbox output shaft end cap, as shown in figure 3, former reduction gearbox output shaft 6 and oil sealing
5 match, and prevent the gear oil of output shaft end from leaking out, the also PVC dustproof cover 4 cooperated with oil sealing 5, in the outer of the output shaft 6
End is equipped with reduction gearbox output shaft end cap 3.Former reduction gearbox output shaft end cap 3 and PVC dustproof cover 4 are removed, dismounting is not needed and slows down
Case output shaft 6 does not destroy former reduction box organizations, will using the unthreaded hole of the present apparatus and 3 position consistency of reduction gearbox output shaft end cap
This leakage-resistant device is fastened on door machine reduction gearbox output shaft outer end, whole to seal output shaft 6 and oil sealing 5, will after the completion of fastening
Sealant is smeared at the gap that the present apparatus is contacted with reduction gearbox, realizes comprehensive sealing.Adverse circumstances locating for the door machine are prevented
Under, ore in sand form dust invades at output shaft 6 and 5 gap of oil sealing, causes the heel and toe wear of output shaft 6, defeated so as to cause reduction gearbox
The leakage of gear oil at shaft 6, the gear oil leaked out when oil leak is serious can cover whole door machine vehicle surface, cause serious safety hidden
Suffer from.The present apparatus realizes comprehensive sealing, has prevented security risk, has saved use cost, practical.
The door machine walking mechanism reduction gearbox output shaft leakage-resistant device can integrally be rushed using sheet metal through cold stamping
System forms and other machine cuts are process, and sheet metal reference thickness 2mm is advisable.
