Description

IP67 Small-sized Marine motor
Technical field
The utility model relates to field of electromechanical equipment, is the Small-sized Marine motor of a kind of degree of protection IP67 specifically.
Background technology
GB/T4942.1-2006 " the integrally-built degree of protection of electric rotating machine (IP code) classification " specifies:
First bit digital 6 of IP67 is " dirt cipher telegram machine prevents dust from entering completely "; Second-order digit 7 is that " protected against the effects of immersion motor, when motor immerses in the water of authorized pressure after the stipulated time, the inflow of motor should not reach harmful degree.”
For convenience of describing, for Y90L-4-HIP67 marine service motor.Motor operating state is: it is dark that motor immerses about 0.5 ~ 0.8 meter, seawater completely, after driving device work 20 ~ 30min, departs from seawater and leaves standstill 60 ~ 90min; Then the next work period is entered.
Because the rotation of motor shaft brings very large difficulty to the sealing of motor.Especially immerse work in seawater, very high requirement is proposed to the hermetically-sealed construction of motor.Once enter seawater in motor cavity, insulation breakdown, winding will be caused, thus corollary equipment cannot be worked.We, through repeatedly manufacturing experimently and analogue test, have devised the Y90L-4-HIP67 marine service motor met the requirements of the customers.
Summary of the invention
In order to the operational environment meeting motor is harsh, degree of protection requires high technical barrier, we take following technical scheme.Motor comprises flange end cap, shaft-cup, rear end cap, stator, rotor and connector cover, stator is by support, be made up of winding stator core, water-proof cable, rear end cap is stifle, seal with O-ring seals between shaft-cup and flange end cap, the hermetically-sealed construction that O-ring seals and long seam small―gap suture coordinate is adopted between connector cover with support, water-proof cable peculiar to vessel and connector cover adopt packing box seal peculiar to vessel to be connected, and it is characterized in that:
1) flange end cap, adopt 3 cover outside framework oil seals, sealing felt and the hermetically-sealed construction that coordinates of small―gap suture between shaft-cup with rotating shaft;
2) flange end cap, the hermetically-sealed construction that adopts two O-ring seals and long seam small―gap suture to coordinate between rear end cap with support;
3) small―gap suture cooperation refers to fit clearance 0.15≤ic≤0.20mm;
Long seam cooperation refers to mating surface length 15≤L≤20mm.
The beneficial effects of the utility model are:
The hermetically-sealed construction of motor is reliable, can prevent the dust of certain pressure and water from immersing motor internal, meet the seal request of IP67, extend the life-span of motor; Structure is simple, is particularly suitable for the IP67 threephase asynchronous of Y80 ~ 160-H Small-sized Marine and subseries.
Accompanying drawing explanation
Accompanying drawing is installation diagram of the present utility model.
In figure, 1-fluorubber outside framework oil seal 3 (GB/T9877.1-88, the sealing for flange end cap and rotating shaft); 2-shaft-cup; 3-O RunddichtringO (GB/T3452.1-92) wherein, 301-is used for the axial seal of shaft-cup and flange end cap, 302,303-is used for the axial seal of two O-ring seals of flange end cap and support, 304-is used for the axial seal of connector cover and support, 305,306-is for the axial seal of two O-ring seals of rear end cap and support); 4-screw (GB70-85 is connected with flange end cap for shaft-cup); The wear-resisting felt seal bar of 5-immersion oil; 6-flange end cap; 7-bolt (GB5781-2000 is connected with flange end cap for support); 8-stator (801-support, 802-water-proof cable peculiar to vessel, 803-holding screw (GB/T73-85), 804-has winding stator core, 805-lifting bolt (GB/T825-88)); 9-connector cover; 10-bolt (GB/T5783-2000 is connected with connector cover for support); 11-stuffing box peculiar to vessel (degree of protection IP68); 12-rotor; 13-bolt (GB/T5783-2000 is connected with rear end cap for support); 14-deep groove ball bearing (GB/T276-94); 15-wavy spring sheet (JB/T7590-2005); 16-rear end cap.
