Abstract
The invention discloses a waterproof motor. The waterproof motor comprises a shell and a power output shaft, the power output shaft extends towards the right and extends out of the shell, the power output shaft is provided with a bearing, an outer ring of the bearing is fixed on the shell, a sealing ring is fixed in the shell, the power output shaft is sleeved by the sealing ring, the sealing ring is positioned at the left side of the bearing, the inner surface of the sealing ring is provided with annular grooves, the annular grooves are filled with non-hydrophilic lubrication grease, the shell is provided with a water leakage chamber positioned at the right side of the bearing, the power output shaft is provided with a water-retaining disc, the water-retaining disc is positioned in the water leakage chamber, and the lower part of the water leakage chamber is provided with a water leakage hole. The waterproof motor is advantaged by good waterproof effect and simple structure.
Description
Technical field
The present invention relates to technical field of motors, especially relate to a kind of waterproof machine.
Background technology
Motor such as on air-conditioner outdoor unit needs to have good water resistance.But the many modes by arranging multi-sealed ring of this type of waterproof machine are solved at present.Obviously, such mode or poor effect or structure comparatively complicated.
Summary of the invention
The object of this invention is to provide a kind of waterproof machine, it has the better and simple feature of structure of waterproof effect.
The technical solution adopted in the present invention is: waterproof machine, comprise housing and power output shaft, this housing is stretched out to the right after this power output shaft extends, and this power output shaft is provided with bearing, the outer ring of this bearing is fixed on this housing, described housing internal fixtion has sealing ring, sealing snare is on this power output shaft, sealing circle is positioned at the left side of this bearing, and the inner surface of sealing circle is provided with cannelure, non-hydrophilic lubricant grease is filled with in this cannelure, simultaneously, the right side this housing being positioned at this bearing is provided with the chamber that leaks, this power output shaft is provided with water retaining disk, this water retaining disk is positioned at this chamber that leaks, and this leaks, the bottom in chamber is provided with leaking hole.
The right flank of described water retaining disk is provided with the guiding gutter being tangential on this power output shaft.
The present invention is advantageously: waterproof effect is better and structure is simple.The water retaining disk of waterproof machine of the present invention can stop that rainwater enters the enclosure interior of this motor, the less water droplet of part can stop by the lubricant grease of non-hydrophilic, then this motor is made to have splendid waterproof effect, and the change that this motor is made relative to original structure is less, structure is comparatively simple.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the front sectional view of embodiments of the invention;
Fig. 2 is the right view of water retaining disk of the present invention.
In figure: 10, housing, 11, leak chamber, 111, leaking hole; 20, power output shaft, 21, water retaining disk, 211, guiding gutter; 30, bearing; 40, sealing ring, 41, cannelure.
Embodiment
Embodiment, is shown in shown in Fig. 1 and Fig. 2: waterproof machine, comprises housing 10 and power output shaft 20.This power output shaft 20 extend out to the outside of this housing 10 to the right after extending, and this power output shaft 20 is provided with bearing 30, and the outer ring of this bearing 30 is fixed on this housing 10.Such as, the outer ring of this bearing 30 and this housing 10 interference fit.Further say, this housing 10 internal fixtion has sealing ring 40, and sealing circle 40 is enclosed within this power output shaft 20.Sealing circle 40 can be elastomeric material preparation.Sealing circle 40 is positioned at the left side of this bearing 30, and the inner surface of sealing circle 40 is provided with cannelure 41, is filled with lubricant grease (not shown on figure) in this cannelure 41, is preferably non-hydrophilic lubricant grease.Like this, the moisture crossing this bearing 30 is difficult to cross that this lubricant grease is then fabulous has carried out waterproof to this motor.Meanwhile, the right side this housing 10 being positioned at this bearing 30 is provided with the chamber 11 that leaks, and this power output shaft 20 is provided with water retaining disk 21, and this water retaining disk 21 is positioned at this chamber 11 that leaks, and this leaks, the bottom in chamber 11 is provided with leaking hole 111.Like this, water droplet cannot cross this water retaining disk 21, and after this water retaining disk 21 rotates, and water droplet to be collected in time in this chamber 11 of leaking and flowed away in this leaking hole 111 under the influence of centrifugal force.
Further say, the right flank of this water retaining disk 21 is provided with the guiding gutter 211 being tangential on this power output shaft 20.Like this, this water retaining disk 21 is convenient to water droplet and is thrown away more rapidly after rotating.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
