Abstract
The utility model discloses a sealing assembly for spindles of motors, which comprises a spindle of motor and an end cover. The spindle on outer portion of the end cover is provided with a hydro-extracting ring slot on which a hydro-extracting ring is arranged in a sleeve mode. A protective cover is arranged on the inner side of the hydro-extracting ring slot and the hydro-extracting ring, and the protective cover is arranged on the surface of outer end of the end cover. The sealing assembly for spindles of motors is simple in structure, and brings convenience to users to use and assembly. The hydro-extracting ring and the protective cover functions as a dual-seal for the spindles of the motors with excellent protective effects. Simultaneously, the noise and loss are reduced, the service life of the motor is prolonged, and the working efficiency of the motor is improved.
Description
Technical field
The utility model relates generally to a kind of motor seal parts, relates in particular to a kind of machine shaft black box.
Background technology
At present, machine shaft uses the oil sealing sealing device usually, is with an oil sealing in the periphery of axle, all can not reach the requirement of protection when the rotation of axle with when static, and sealing effectiveness is not fine.Owing to cooperates tightlyer between oil sealing and the rotating shaft, mechanical loss increases, and causes the efficiency of motor reduction, and rotating shaft is worn and torn, it is big to produce certain heat, noise, has had a strong impact on sealing effectiveness and useful life, has influenced the use value of machine shaft sealing device.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of machine shaft sealing to be provided
Assembly, when having solved existing machine shaft and adopting oil sealing sealing, mechanical loss increases, and causes efficiency of motor to reduce, and rotating shaft is worn and torn, and it is big to produce certain heat, noise, has a strong impact on problems such as sealing effectiveness and useful life.
The utility model is achieved through the following technical solutions:
A kind of machine shaft black box, include machine shaft and end cap, it is characterized in that: the rotating shaft of described end cap outside is provided with the water dumping annular groove, be set with throw rijng on the described water dumping annular groove, the installed inside of described water dumping annular groove and throw rijng has protective cover, and described protective cover is installed on the outer face of end cap.
Described machine shaft black box is characterized in that: the inboard of described protective cover is provided with outside protrusion, and protective cover becomes by the cold-rolled steel sheet punching out, or cast iron processes.
The utility model plays the effect of dual-seal to machine shaft by throw rijng and protective cover; protect throw rijng not to be affected by the external environment simultaneously; better sealing effectiveness and requirement of shelter have been reached; and protective cover is installed on the end cap, and inboard outwards protrusion, and anti-sealing enters; throw rijng adopts elastic material to overcome the rotating shaft frictional heating; heat insulation, noise is little, has reduced the loss of motor, has improved the operating efficiency of motor.
The utility model has the advantages that:
The utility model is simple in structure, easy to install, by throw rijng and protective cover machine shaft is played the effect of dual-seal, and protection effect is good, has reduced noise simultaneously, has reduced loss, has improved motor useful life and operating efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
