Abstract
The utility model discloses a kind of motor sealing structure, its drip irrigation device comprises labyrinth ring and bearing end cover, the outwardly formation positioning tooth in described labyrinth ring side, described bearing end cover is provided with the location notch coordinated with positioning tooth, annular seal space is formed between labyrinth ring and bearing end cover, be provided with V-arrangement oil sealing in described annular seal space, described V-arrangement oil sealing both sides abut with labyrinth ring and bearing end cover respectively, are filled with lubricating grease in described annular seal space.The utility model sealing effectiveness is better.
Description
Technical field
The utility model relates to a kind of motor, and more particularly, it relates to a kind of motor sealing structure.
Background technology
At present, motor at a high speed, energy-conservation, quiet, high-power future development, as the industries such as coal the fire-proof motor that uses etc. more than 60% by slowspeed machine in original replace by high-speed electric expreess locomotive.In order to prevent dust from entering, general employing labyrinth ring seals, then is sealed by general annular seal circle, and the both sides of sealing ring can not fully abut with labyrinth ring and bearing end cover, and sealing effectiveness is not good.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of sealing effectiveness good motor sealing structure.
For achieving the above object, the utility model adopts following technical scheme, comprise labyrinth ring and bearing end cover, the outwardly formation positioning tooth in described labyrinth ring side, described bearing end cover is provided with the location notch coordinated with positioning tooth, is formed with annular seal space between labyrinth ring and bearing end cover, is provided with V-arrangement oil sealing in described annular seal space, described V-arrangement oil sealing both sides abut with labyrinth ring and bearing end cover respectively, are filled with lubricating grease in described annular seal space.
Preferably, V-arrangement oil sealing side stretches out formation seal, and the side of described seal abuts with labyrinth ring.
Preferably, be provided with buffering slot to make way in seal, described buffering slot to make way slowly to be narrowed to both sides by middle part and is circular arc.
Preferably, the sidewall of V-arrangement oil sealing outwards caves in circular arc.
The utility model hinge structure is compared to be had: be formed with annular seal space between labyrinth ring and bearing end cover, V-arrangement oil sealing is provided with in annular seal space, V-arrangement oil sealing both sides abut with labyrinth ring and bearing end cover respectively, be filled with lubricating grease in annular seal space, such V-arrangement oil sealing that arranges has certain outside tension force, ensures fully to abut with the labyrinth ring of both sides and bearing end cover, prevent dust from entering, lubricating grease is set simultaneously, can prevents dust from entering further, also have the effect of anti-water for cooling.
Accompanying drawing explanation
Fig. 1 is the cutaway view of motor sealing structure;
Fig. 2 is the cutaway view two of motor sealing structure;
Fig. 3 is A portion enlarged drawing in Fig. 2.
Reference numeral: 1, bearing end cover, 2, labyrinth ring, 3, annular seal space, 4, V-arrangement oil sealing, 5, seal, 51, slot to make way.
Embodiment
With reference to accompanying drawing, the utility model motor sealing structure embodiment is described further.
A kind of motor sealing structure, comprise labyrinth ring 2 and bearing end cover 1, the outwardly formation positioning tooth in labyrinth ring 2 side, bearing end cover 1 is provided with the location notch coordinated with positioning tooth, annular seal space 3 is formed between labyrinth ring 2 and bearing end cover 1, V-arrangement oil sealing 4 is provided with in annular seal space 3, V-arrangement oil sealing 4 both sides abut with labyrinth ring 2 and bearing end cover 1 respectively, lubricating grease is filled with in annular seal space 3, the V-arrangement oil sealing 4 that arranges like this has certain outside tension force, ensure fully to abut with the labyrinth ring 2 of both sides and bearing end cover 1, prevent dust from entering, lubricating grease is set simultaneously, can prevent dust from entering further, also the effect of anti-water for cooling is had.
V-arrangement oil sealing 4 side stretches out and forms seal 5, and the side of described seal 5 abuts with labyrinth ring 2, and such is arranged so that abutting is more abundant, and sealing effectiveness is better, also to a certain degree limits the position of V-arrangement oil sealing 4, V-arrangement oil sealing 4 is connected more stable.
Buffering slot to make way 51 is provided with in seal 5, described buffering slot to make way 51 slowly to be narrowed to both sides by middle part and is circular arc, has the space of deformation when making seal 5 be subject to abutting power like this, ensure that while fully abutting, ensure that seal 5 is not easy to damage, ensure sealing effectiveness.
The sidewall of V-arrangement oil sealing 4 outwards caves in circular arc, such dispersion being provided with the power of helping, and avoids V-arrangement oil sealing 4 can be stressed excessive and damage at a certain position, ensure that abutting of V-arrangement oil sealing 4 and both sides labyrinth ring 2 and bearing end cover 1, thus guarantee sealing effectiveness.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to the above embodiments, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
