Description
Technical field
The utility model is related to technical field of wet metallurgy, and in particular to a kind of end cover for speed reducer.
Background technology
In hydrometallurgical technology, the valuable metal in metalliferous material is leached using acid, widely used leaching tanks into
Row leaches operation, and leaching tanks accelerate extraction time using stirring, and leaching effect can be improved by being passed through oxygen and improving temperature, usually temperature
Degree control is at 70 DEG C or so.During leaching tanks temperature is improved using steam, the deceleration of the vertical stirring of acid mist can be generated
Machine causes to corrode, and oil sealing can cause hardening and cracking phenomena under long-term high temperature and acid mist corrosiveness, lose sealing function,
Deceleration machine oil can cause speed reducer serious wear after being lost in along oil sealing, affect the service life of speed reducer, the prior art can not
It solves the above problems.
Utility model content
The purpose of this utility model is to solve in the prior art since long term high temperature and acid mist corrosion cause speed reducer
Oil sealing hardening and cracking phenomena and influence speed reducer service life the problem of, provide a kind of sealed end for speed reducer
Lid.
In order to achieve the above object, the utility model uses following technical scheme：A kind of end cover for speed reducer,
Including end cap ontology, installation through-hole is provided on end cap ontology, the upper end anchor ring of end cap ontology is equipped with to be positioned with deceleration machine support
First positioning annular table, first positioning annular table be equipped with second positioning annular table, second positioning annular table inside be equipped with
Ring flat-plate is sealed, the lower end anchor ring of end cap ontology is equipped with the positioning convex shoulder positioned with speed reducer, and the lower face of end cap ontology may be used also
Dismantling connection has sealing gland, and annular seal space is equipped with, and annular seal space is co-axially located at end cap sheet between sealing gland and sealing ring flat-plate
The center of body, annular seal space are interior equipped with the first oil sealing, the second oil sealing.
Further, the first oil sealing, the second oil sealing are the outside framework oil seal that material is polytetrafluoroethylene (PTFE).
Further, sealing gland has been bolted in the lower face of end cap ontology.
Further, end cap ontology is equipped with uniformly distributed inside and outside two ring through hole.
The utility model has the advantages that relative to the prior art：The utility model is used for the close of speed reducer
Sealing end lid by setting sealing gland on end cap ontology, installs additional in the annular seal space formed between sealing gland and sealing ring flat-plate
First oil sealing, the second oil sealing, significantly reduce the oil leakage phenomenon caused by speed reducer oil sealing actual effect, and repair teams and groups are overhauling more
The first oil sealing for being located at upside is regularly replaced during changing, ensures the service life of speed reducer at 2 years or more, while is strong
Change shift group will uniformly feed during charging, prevent stirring suppress it is curved cause speed reducer failure, production team is in the mistake used
Periodic maintenance in journey supplements deceleration machine oil in time, achievees the purpose that prolonged deceleration machine service life, reduces maintenance
Labor intensity can be such that the service life of speed reducer is up to 2 years or more under periodic maintenance maintenance cooperation.
