Abstract

The utility model discloses a motor slide bearing breathing helmet breathes a mouthful installation stainless steel condenser pipe at motor slide bearing, installs the top at the condenser pipe with the breathing helmet again. The utility model discloses a set up the oil mist that the condenser pipe makeed bearing when operation high temperature produce and obtain the cooling at the in -process that rises, flow back once more to the bearing, improved the problem of high -voltage motor breathing helmet oil impregnate, practiced thrift the cost, very big reduction the fault rate of motor.

Description

A kind of motor sliding bearing breathing helmet

Technical field

This utility model relates to electromechanical engineering technical field, particularly to a kind of motor sliding bearing breathing helmet.

Background technology

In the production process of chemical plant and large enterprise, motor is main power source, once break down, the loss that whole production is brought is sizable, and especially large and medium-sized high-tension motor can badly influence whole production process. Find according to the statistics of electrical fault, bearing damage or the electrical fault caused because of bearing damage, account for more than the 70% of the whole fault of motor, for this by motor bearings fault occurs that more motor be analyzed finding, there is the sign of leakage of oil in the bearing mostly counted, and the mist of oil that wherein most produces when being because bearing bush temperature height, mist of oil is by breathing helmet and condenses and form oil droplet outflow herein, therefore that the transformation of bearing shell motor breathing helmet is very necessary to solve Leakage.

Summary of the invention

The purpose of this utility model is in that to provide a kind of motor sliding bearing breathing helmet, to solve the problem that when motor runs, lubricating oil atomization exosmoses along breathing helmet. Described sliding bearing breathing helmet can reduce motor leakage of oil, saves cost, reduces the greasy dirt pollution to environment.

The purpose of this utility model is achieved through the following technical solutions.

A kind of motor sliding bearing breathing helmet of the present utility model, it is characterised in that install rustless steel condensing tube at motor sliding bearing pneumostome, then breathing helmet is arranged on the top of condensing tube.

The length of described rustless steel condensing tube is 15cm��20cm.

Described rustless steel condensing tube adopts with sliding bearing pneumostome threadeds, and seals in junction.

Motor oil leakage problem is primarily due to the bearing bush temperature higher lubricating oil atomization that causes when motor runs, and breathing helmet is the passage that bearing shell is connected with outside air, and therefore mist of oil infiltrates into outside breathing helmet by space, causes bearing shell permeability. This utility model is by installing the condensing tube of appropriate length so that mist of oil condense in uphill process forms oil droplet and be back in the bearing shell of motor, reaches the purpose of solution bearing shell breathing helmet Leakage.

The beneficial effects of the utility model: motor sliding bearing breathing helmet simple in construction of the present utility model, easy for installation; Can effectively control the phenomenon of motor leakage of oil, and then greatly reduce the fault rate of motor.

In figure, 1 is sliding bearing pneumostome, and 2 is breathing helmet, and 3 is condensing tube.

Detailed description of the invention

For solving the problem that when high-voltage motor runs, lubricating oil atomization exosmoses along breathing helmet, the structure of high-voltage motor bearing shell breathing helmet is transformed. Fig. 1 is the sliding bearing breathing helmet before transformation, and sliding bearing pneumostome connects a short beam hanger that adds, then installs breathing helmet. Cause lubricating oil atomization because bearing bush temperature is higher, and breathing helmet is the passage that bearing shell is connected with outside air, mist of oil uphill process cannot condense in time, cause that mist of oil condensation infiltrates into outside breathing helmet, cause bearing shell permeability.

According to sliding bearing breathing helmet of the present utility model, its structure is as shown in Figure 2. Thread size according to different model motor processes the rustless steel condensing tube 3 of a long 15CM, then condensing tube 3 is arranged on motor sliding bearing pneumostome 1 place, and carries out sealing with fluid sealant, then breathing helmet 2 is arranged on the top of condensing tube 3, tightens. Unsintered tape can be used to be wound at the screw thread mouth place that sliding bearing pneumostome 1 is connected with condensing tube 3.
