The ultrasound wave water immersion detecting system is rotating-table apparatus under water
Technical field
The utility model relates to a kind of ultrasound wave water immersion detecting system, is specifically related to rotating-table apparatus under water.
Background technology
Rotating disk is a ultrasound wave water immersion detecting system device commonly used under water, the detected workpiece that driving is immersed in the water rotates with maximum 200RPM rotating speed, and the diameter of rotating disk is according to application need, and maximum possible reaches 1 to 2 meter, load-bearing capacity is according to application need, and maximum possible reaches more than 1 ton;
Also there is bigger upsetting moment load in the static load that rotating disk mechanism is subjected to simultaneously for axially.
Owing to need be operated under water, existing rotating disk mechanism design can not meet the demands usually, show that thrust bearing commonly used often can not bear big axial load lotus upsetting moment, underwater operation needs strict water-stop design, the processing of bearing lubrication and maintenance also has very big challenge, the layout of mechanism often need to require little rotating disk cross section, and the combination bearing design is difficult to little cross section.
The utility model content
The purpose of this utility model provides a kind of ultrasound wave water immersion detecting system rotating-table apparatus under water, to overcome the above-mentioned defective that prior art exists.
Ultrasound wave water immersion detecting system of the present utility model is rotating-table apparatus under water, and the supporting disk, rotating disk that comprise rotating disk, turntable bearing, are provided with center pit drive rotating shaft and drive motor;
Described turntable bearing is arranged on the outer rim between rotating disk and the supporting disk, and an end of described rotating disk driving rotating shaft passes the center pit of described supporting disk, fixedlys connected with rotating disk, and the other end that rotating disk drives rotating shaft is connected with drive motor.
Ultrasound wave water immersion detecting system of the present utility model is rotating-table apparatus under water, mechanism is simple, the maintenance of bearing realizes easily, turntable bearing is having the incomparable advantage of other Bearning mechanism aspect axial load and the upsetting moment load, sectional area is little, and is compact to design, and the volume weight sectional area reduces more than 50%, load capacity improves more than 5 times, can surpass more than 1 ton by load capacity.
