Abstract
The utility model discloses an electric locomotive gear box magnetic fluid sealing device. The electric locomotive gear box magnetic fluid sealing device comprises a neck ring and a rotary shaft which are arranged on a gear box, wherein a gap is formed between the gear box and the rotary shaft, a magnetic field is arranged at the position of the neck ring, a magnetic loop is formed between the neck ring and the rotary shaft, and magnetic fluid can be absorbed in the magnetic loop so that air does not circulate, and accordingly the gap is sealed. The situation that the air does not circulate is guaranteed, so that oil inside the gear box cannot flow out through the gap, and oil leakage is effectively prevented. Due to the fact that exhaust vents are formed in the top portion of the gear box, the negative pressure inside the gear box cannot exceed designed pressure and oil leakage will not occur. Due to the fact that an oil-resistant rubber blanket is arranged inside the magnetic loop, not only can influences, caused by locomotive vibration, to the magnetic field be reduced, but also the effects of resisting oil and sealing are achieved, and the sealing device is abrasion-resistant. Base fluid of the magnetic fluid is grease so that the effect of lubricating can be achieved.
Description
Technical field
The utility model relates to a kind of electric locomotive gear-box, particularly a kind of electric locomotive gear-box device for sealing magnetic fluid.
Background technique
Electric locomotive is to realize the electric locomotive running by the gearwheel that motor pinion drives in the rotating shaft.Big small gear interlock need be lubricated in this process, is by gearwheel the machine oil in the gear-box to be taken to big small gear bite to realize.And the problem of gear-box leakage of oil from the sixties until all fail to deal with problems now always.The minor issue of gear-box leakage of oil generally is to change wool felt to refuel again, and big problem burns to big small gear that then to need to change wheel right, even can burn motor and cause loss up to a million, causes circuit such as parking indirect loss etc. also can't calculate.Therefore, electric locomotive gearbox leakage need obtain basic solution.
Existing domestic and international electric locomotive gearbox leakage generally is to solve like this: SIEMENS adopts the labyrinth form to solve the leakage of oil problem, and cast aluminium gear-box cost is up to 30000 yuan, and must partly do completely the bogie of locomotive and transform.This is insurmountable on the line several ten thousand locomotives.This scheme only realizes in the electric locomotive of redesign and manufacturing.Also have a kind of Americanized gear-box to make with macromolecular material, can the sort of material price up to more than 1000 yuan one kilogram, can't accept at all.The domestic real solution of neither one of up to the present going back remains and continues to use wool felt and do motive sealing between gear-box and the rotating shaft.This sealing from the sixties in last century till now, leakage of oil always can not solve.
The model utility content
At the problem that prior art exists, the utility model aims to provide a kind of electric locomotive gear-box device for sealing magnetic fluid that can prevent leakage of oil.
The utility model provides a kind of electric locomotive gear-box device for sealing magnetic fluid, comprise eckband and the rotating shaft be located on the described gear-box, and be formed with a space between described gear-box and the described rotating shaft, described eckband place is provided with magnetic field, and form magnetic loop between described eckband and the described rotating shaft, magnetic fluid is adsorbable to cause atmosphere draught-free in described magnetic loop, in order to seal described space.
Preferably, the top of described gear-box is provided with exhaust port.
Described eckband place is provided with permanent magnet.
Be provided with oil-resistant rubber insert in the described magnetic loop and can reduce the influence of locomotive vibration, and the hardness of described oil-resistant rubber insert is HB70 magnetic field.
Be provided with flinger ring between described rotating shaft and the described gear, and the side of described flinger ring is provided with described device for sealing magnetic fluid.
A kind of electric locomotive gear-box device for sealing magnetic fluid that the utility model provides, described magnetic fluid is adsorbed in the described magnetic loop, can seal the space between gear-box and the rotating shaft, guarantees that air can not circulate, oil in the described gear-box can not outflow by the gap, has effectively prevented leakage of oil; Described exhaust port is located at the top of described gear-box, makes that the negative pressure in the described gear-box can not surpass design pressure, and therefore the negative pressure in the described gear-box can not exceed design pressure and leakage of oil; Described oil-resistant rubber insert not only can reduce the influence of locomotive vibration to magnetic field, and its hardness is HB70, can play seal action again by oil resistant, and have wear resistance; The base fluid of described magnetic fluid is a grease, so can also play lubrication.
