Description
Technical field
This utility model relates to a kind of shaft seal structure, the shaft seal structure of a kind of motor axle head.
Background technology
Having motor output shaft end at motor left bearing, its load is more than right bearing, and therefore the caloric value of left bearing is bigger, it is necessary to left bearing is taked certain cooling down measure to ensure that left bearing is in normal duty.One of cooling down measure that left bearing is taked by motor is that the drive end bearing bracket installing left bearing is designed to inner chamber sandwich, stores cooling oil in inner chamber interlayer, and left bearing can be played good cooling down effect by this structure.Owing to inner chamber interlayer storing cooling oil, therefore, drive end bearing bracket is provided with shaft seal structure.Existing drive end bearing bracket shaft seal structure is arranged on the motor shaft two ends running through drive end bearing bracket inner chamber interlayer, being wherein a kind of radial shaft seal structure near left bearing, this shaft seal structure coordinates with motor sealing with static interior oil sealing cap endoporus middle concave annular groove setting-in felt circle and forms.This radial shaft seal simple in construction, it is possible to play the effect stopped in drive end bearing bracket inner chamber interlayer in cooling oil inflow motor inner chamber.But, the sealing property of radial shaft seal depends on sealing ring and motor axle mated condition, the once abrasion of felt circle, and its sealing property just declines, and cooling down oil in drive end bearing bracket inner chamber interlayer will inflow motor inner chamber.
Summary of the invention
This utility model is for the deficiencies in the prior art, there is provided one can keep in drive end bearing bracket inner chamber interlayer and be in preferable sealing state near left bearing one end, stop the cooling oil in drive end bearing bracket inner chamber interlayer will the high pulling torque marine service motor combined type shaft seal structure of inflow motor inner chamber.
This utility model is achieved through the following technical solutions technical goal.
High pulling torque marine service motor combined type shaft seal structure, is arranged on and has between the drive end bearing bracket of inner chamber interlayer, motor shaft；Being respectively equipped with the outer oil sealing cap with motor shaft matched in clearance, interior oil sealing cap before and after described drive end bearing bracket inner chamber interlayer, interior oil sealing cap is arranged on the left side of left bearing；In described drive end bearing bracket inner chamber interlayer, the side near outer oil sealing cap is provided with automatic tightening formula shaft seal structure；Fixed cover that described automatic tightening formula shaft seal structure includes being sleeved on the most successively on motor shaft, compression spring, sliding sleeve, O-ring seals, axle sleeve, sealing ring I, fixed cover is fixedly connected on motor shaft；Described inner hole of shaft sleeve and motor shaft outer wall matched in clearance, be embedded in O-ring seals and constitute radial shaft seal in seam on the right side of its endoporus；Described axle sleeve is provided with relative seam with outer oil sealing cap, is provided with sealing ring I and constitutes axial axis seal structure in relative seam；Seam endoporus matched in clearance on the right side of described sliding sleeve endoporus and motor shaft outer wall matched in clearance, left end outer wall and axle sleeve；Described sliding sleeve left end stretches on the right side of axle sleeve in seam endoporus, is pressed on O-ring seals；Described interior oil sealing cap endoporus middle concave annular groove setting-in felt circle seals with motor shaft and coordinates；It thes improvement is that: it is protruding that described interior oil sealing cap left side is provided with hoop, fixed cover right side is provided with hoop annular groove, and interior oil sealing cap left side hoop projection stretches in the hoop annular groove of fixed cover right side, and matched in clearance, form labyrinth seal structure, in labyrinth, fill grease.
In said structure, described fixed cover right side is provided with conical ring limit, forms disc.
This utility model compared with prior art, has the positive effect that:
1. it is provided with labyrinth seal structure between fixed cover and interior oil sealing cap in drive end bearing bracket inner chamber interlayer, grease is filled in labyrinth, stop and drive end bearing bracket inner chamber interlayer cools down in oil inflow motor inner chamber, a seal structures is being added near left bearing side, being in preferable sealing state near left bearing one end in keeping drive end bearing bracket inner chamber interlayer, cooling down oil in prevention drive end bearing bracket inner chamber interlayer will inflow motor inner chamber.
2. it is provided with automatic tightening formula shaft seal structure in drive end bearing bracket inner chamber interlayer so that O-ring seals and motor shaft, between sealing ring I and sealing ring, be in tight fit state all the time, long-term ensures drive end bearing bracket sealing property.
3. fixed cover right side is provided with conical ring limit, forms disc, and the cooling oil that will accumulate in fixed cover and interior oil sealing cap junction is thrown away, the sealing reliability of close left bearing one end in improving drive end bearing bracket inner chamber interlayer further.
