Abstract
The utility model discloses a hub type direct current motor waterproof structure, which aims to resolve the problem that the existing motor is easy to be invaded with water. The hub type direct current motor waterproof structure is provided with a stator connected with supporting shafts, a stator winding is arranged on the stator, an outgoing line of the stator winding is led out from a shaft hole of the supporting shaft on one side, the supporting shafts on two sides of the stator are connected with motor end covers equipped with bearing chambers via bearings, inside spigots of the two motor end covers are respectively connected with a motor hub, sealing ring grooves are arranged on the peripheries of the spigots of the motor end covers, and sealing rings are arranged in the sealing ring grooves. By utilizing the above waterproof structure, the problem that the existing motor is easy to be invaded by water is resolved by respectively employing the sealing rings, waterproof oil seals and waterproof nuts. The motor utilizing the waterproof structure is fine in effects after repeatedly tests, the motor is totally immersed in water for half an hour after load operation for one hour, operators find that the inside of the motor is dry without water invasion after opening the motor end covers.
Description
Technical field
The utility model relates to a kind of structure of hub-type direct current machine waterproof.
Background technology
What used in the market electric motor car adopted mostly is the hub-type direct current machine, problem of this motor ubiquity: that rains exactly and into intakes easily in the motor.This problem can't fundamentally be solved always completely, even motor in short-term can waterproof, but sustainability is not strong, in use for some time also can be for various reasons, and the water-proof function variation causes the motor water inlet.
This motor water inlet mainly is present in three places: the firstth, and motor shaft and the water inlet of end cap oil sealing place; The secondth, the water inlet of motor shaft line outlet; The 3rd is end cap seam and the water inlet of motor wheel hub joint; In order to address these problems, normally at motor shaft line outlet place and end cap seam and motor wheel hub joint come water-tight by the mode of playing glue, this kind measure has following shortcoming: the firstth, and glue might not be coated with evenly or not be coated with to put in place and cause motor to leak, bad during this type of motor water-proof function fashion, water resistance can not get guaranteeing; It is bigger that second glue is influenced by various factors, and the motor waterproof life-span is not long; The 3rd glue makes electrical machmary maintenance become complicated.
The utility model content
For overcoming above-mentioned defective, the purpose of this utility model is to provide a kind of water resistance good, the hub-type direct current machine waterproof construction that the life-span is long.
For achieving the above object, the structure of hub-type direct current machine waterproof of the present utility model has the stator that is connected with back shaft, is provided with stator winding on stator, and the lead-out wire of stator winding is drawn by the axis hole of a side back shaft; The back shaft of stator both sides links to each other with the electric motor end cap that is provided with bearing chamber by bearing, the inboard seam of two electric motor end caps links to each other with motor wheel hub, electric motor end cap and motor wheel hub lump together and form the rotor chamber, be provided with rotor magnetic pole with respect to stator within it, upwards be provided with o-ring groove in described electric motor end cap seam week, in described o-ring groove, be provided with sealing ring.
Particularly, between described electric motor end cap and back shaft, be provided with two waterproof oil sealings.
Particularly, the lead-out wire of described stator winding is arranged with sleeve pipe outward, and described sleeve pipe is formed with ring uplift at back shaft axis hole place, to should ring uplift and back shaft be provided with hat waterproof nut.
Adopt above-mentioned waterproof construction, utilize sealing ring, waterproof oil sealing and waterproof nut to solve the problem of existing direct current machine water inlet respectively, this motor is through repetition test repeatedly, effect is fine: the motor load operation is after 1 hour, submerge half an hour, open electric motor end cap and find that the dry nothing water inlet of motor internal phenomenon takes place.
Description of drawings
Fig. 1 is the cross-sectional schematic of the utility model hub-type direct current waterproof machine structure embodiment.
Specific implementation method
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1, a kind of hub-type direct current machine of the utility model waterproof construction comprises the stator 2 that is connected with back shaft 1, is provided with stator winding on stator, and the lead-out wire 3 of stator winding is drawn by the axis hole of a side back shaft; The back shaft of stator both sides links to each other with the electric motor end cap 4 that is provided with bearing chamber by bearing, the inboard seam of two electric motor end caps links to each other with motor wheel hub 5, electric motor end cap 4 and motor wheel hub 5 lump together and form the rotor chamber, be provided with rotor magnetic pole with respect to stator within it, on two electric motor end cap seams, seal groove is arranged, the cross section of described seal groove can design as required, as can be for rectangle, trapezoidal or O shape; Add corresponding sealing ring 6 (being the O RunddichtringO among Fig. 1) during assembling within it, this design can effectively stop the water of motor outside to infiltrate from end cap seam and motor wheel hub joint.
Improve further as the utility model, between described electric motor end cap and back shaft, be provided with two waterproof oil sealings 7.Like this, even outside oil sealing is destroyed, inner oil sealing is normal waterproof still,
Improve further as the utility model, the lead-out wire of described stator winding is arranged with sleeve pipe outward, and described sleeve pipe is formed with ring uplift 8 at back shaft axis hole place, forms the waterproof plug, to should ring uplift and back shaft be provided with hat waterproof nut 9.The waterproof nut closely cooperates ring uplift and the motor shaft wire hole on the sleeve pipe, and anti-sealing enters from the motor shaft line outlet.
Above-mentioned the utility model hub-type direct current machine waterproof construction, problem at present motor waterproof existence, design the motor of electric motor car that a kind of water resistance and waterproof life-span all be satisfied with, this motor is through repetition test repeatedly, effect is fine: the motor load operation is after 1 hour, submerge half an hour, open electric motor end cap and find that the dry nothing water inlet of motor internal phenomenon takes place.
Above example only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
