Description
Technical field
The present invention relates to electric motor end cap technical field, in particular to a kind of electric motor end cap.
Background technique
Electric motor end cap: being exactly the lid of motor case.Generally divide front cover and rear cover, for fixing and supporting machine shaft
, the general intermediate motor shaft sleeve that is equipped with is used to across motor shaft.
Traditional electric motor end cap general structure is simple, and the preceding door of end cap is generally entirety and is stamped to form, and some is equipped with and opens
For mouth convenient for radiating when motor work, some plays for sealing prevents dust and waterproof action, can not manually adjust opening and sealing
State, to prevent electric motor end cap from being provided simultaneously with heat dissipation, dust-proof good feature, and the preceding door sealed is in maintenance motor shaft
When need integral demounting end cap, cause maintenance inconvenient.
Summary of the invention
The object of the invention is that cannot make itself by door before adjusting in order to solve above-mentioned electric motor end cap while having
Standby heat dissipation and dust-proof function, lead to inconvenient problem with use and provide a kind of electric motor end cap, have adjustable dust excluding plate, dissipate
Hot good dustproof effect, convenient for motor shaft maintenance the advantages of.
The present invention is achieved through the following technical solutions above-mentioned purpose, a kind of electric motor end cap, including end cap ontology, the end
One end of lid ontology is open end, and the other end is arranged the preceding door that is made of dust-proof mechanism and fixed plate, the dust-proof mechanism and
It is connected between the fixed plate by motor shaft sleeve, the motor shaft sleeve is made of fixed hub and rotary sleeve, described solid
The multiple and annular outer wall being placed equidistant in the fixed hub is arranged in fixed board, forms heat dissipation between the two neighboring fixed plate
Mouthful, the dust-proof mechanism includes the swivel becket with end cap inner body wall rotation connection, and wall circular is equidistant in the swivel becket
Several dust excluding plates are set, and the other end of the dust excluding plate connects the rotary sleeve, the rotary sleeve and the fixing axle
It is rotatablely connected between set, and is fixed by position-limit mechanism.
Preferably, it states position-limit mechanism to be arranged in fixed hub inner wall, rotary sleeve is socketed in the inner wall of fixed hub, rotation
The card slot that the outer wall setting of axle sleeve matches with position-limit mechanism.
Preferably, the position-limit mechanism includes the groove that fixed hub inner wall is arranged in, and spacing tooth is installed in the inside of groove,
The spacing tooth passes through spring and inside grooves elastic connection.
Preferably, the spacing tooth includes tooth body, and the both ends of tooth body are respectively short front end and long rear end, and tooth body and spring
Arc binding face is arranged in opposite one side.
Preferably, the outer wall of the arc binding face and rotary sleeve matches.
Preferably, the sidewall weld support base of the end cap ontology.
Preferably, the quantity of the dust excluding plate and the quantity of thermovent are identical, and the ruler of the size of dust excluding plate and thermovent
It is very little equal.
Preferably, the dust-proof mechanism is mounted on the upper surface of fixed plate.
Compared with prior art, the beneficial effects of the present invention are: by being in by preventing by the front cover portion setting of end cap ontology
Dirt mechanism and fixed plate composition, fixed plate are enclosed around motor shaft sleeve one, and there are thermovents for adjacent fixed plate, dust-proof by rotating
Mechanism, dust excluding plate can cover in thermovent or expose thermovent, facilitate the heat dissipation of motor and dust-proof, work normally in motor
When, dust excluding plate can block thermovent, so that the front cover of end cap is a sealing structure, pass through twisting rotation when needing to radiate again
Axle sleeve opens thermovent and radiates, and motor shaft can also open thermovent when maintenance and be lubricated maintenance, nothing
End cap need to be dismantled, it is easy to use, it is blocked in rotary sleeve and fixed hub rotation process by position-limit mechanism, inside position-limit mechanism
Spacing tooth pushed by spring force and be attached to the surface of rotary sleeve, when the card slot of rotary sleeve and spacing tooth to it is corresponding when limit
Tooth is pushed into card slot and completes detent, and the both ends length of spacing tooth is different, therefore rotary sleeve need to only go into overdrive towards long one
When the rotation of end, spacing tooth can be squeezed out card slot, this position-limit mechanism convenient dust-proofing plate is bonded thermovent completely.
