An apparatus and method are given for stiffening a bottom plate of a spindle motor to improve shock resistance and vibration response, and thereby increase reliability and performance of a disc drive memory system. A stiffener tab for stiffening a foundation plate is linked to the bottom plate, extends from the base plate, and can be dimensioned to fit next to a stator tooth. Stiffening of a bottom plate is especially useful in the case of stamped base plate designs that typically have uniform thickness, whereas cast foundation plate designs are produced with thicker sections. Within an aspect, the present invention stiffens a motor cup portion of the base plate, and replaces stiffness dropped by removal of material from the base plate to form holes for recessing a stator into the base plate. Axial and angular displacement of a spindle engine during shock occasions and vibration are reduced.

The utility model discloses a connecting structure for a motor base plate and a supporting bowl of a voltage stabilizer. The connecting structure comprises a electric motor, a motor supporting plate, a rotating shaft equipment and a voltage stabilizer base plate, wherein the engine is connected with the motor supporting plate and simultaneously a motor equipment is arranged on the engine; the engine supporting plate is linked with the motor foundation plate through screws; the engine base plate is linked with the voltage stabilizer base plate through screws; the rotating shaft gear is organized at one end of a rotating shaft; the rotating shaft is organized on the voltage stabilizer bottom plate and simultaneously the rotating shaft gear can be meshed with the electric motor gear; and holes are created on the still left and the right sides of the electric motor foundation plate and positioning protrusions corresponding to the holes are created on the voltage stabilizer base plate. The connecting structure has the benefit that the mounting hole positions and the gears are adjustable so as to ensure good gear mesh.
A base bowl of a disk drive apparatus includes a motor base disposed around a central axis and a foundation body portion extending radially outward of the engine base. The motor base is constructed of a metallic material of an initial type. The bottom body portion is made of a metallic materials of a second type. Thus, the axial thickness of some of the bottom plate close to the central axis can be significantly reduced and a reduction in the stiffness of the part could be prevented. Further, the motor base carries a flange part and a plastic-type deforming portion. The flange portion and the plastic-type deforming portion are respectively in contact with at least a portion of both axial end areas of an internal end portion of the bottom body portion. Therefore, extraction of the electric motor bottom in the axial path is prevented.
Machine T Slot Bed Plate is a industrial measuring tool used to secure work-piece. Bench workers make use of it for debugging , setting up and maintaining the equipment.upon ask for. Additionally, the working surface provides been treated with the scraping technology, which allows it to really have the V, or U-designed grooves, round holes, slot holes or other that you desire. The raw materials of the cast iron surface area table may be the high -power cast iron HT200-300 whose surface area hardness is definitely of HB170-240. After the two manual handing such as 600℃ to 700℃ artificial annealing as well as 2 to 3 three years of natural aging, the T-slot offers plate flawlessly resists abrasion and provides stable precision.

Before using, we should use noncorrosive gas to completely clean the anti-rust oil and wipe clean with a decreasing cotton.
Cast iron t slot bed plate have to be modified with the varitation gauge to the proper level and the strain on a surface area plate is distributed more than the working surface. Our professional experts are responsible for debugging the surface plates until getting qualified precision grade.
please used carefully and stop collisions ASAP.
After using, please take down the workpieces in case that any deformation happens.
If the top plate is not required for some days, the top should be coated anhydrous acidic anti-rust oil,moisture-proof paper cover, and putted in a clean dry place.
Surface plate ought to be placed on a spot where there’s a circulation of atmosphere which is under continuous temperature control. The plate ought to be in a location away form sunlight and sources of draughts which could cause a vertical gradient of temperature such that the top and underside of the top plate are in different temperatures.
Motor Bases are fabricated of steel which offers a foundation of rugged design, small and smooth in appearance. Bases are design to provide adequate travel, are completely adjustable by the usage of a single adjusting screw and have elongated mounting holes in the bottom plate.
Cast iron surface area plates are also called cast iron system, the cast iron surface plates are produced according to GB4986-85 regular to guarantee the high quality. The products are always converted to ribbed plate or box-type; our business uses the scraping procedure to enhance the precision of the merchandise. Since the items are customized, so the clients can customize the size according to the actual needs. Plurality of cast iron surface area plate could be spliced, once abrasion after use, the plate could be re-restoration scratch to resume its accuracy.Usage1.Suitable for numerous inspections and benchmark planes for accuracy measurement.2.Utilized widely as the measurement benchmark for machine tool inspection and to inspect thedimension precision or operating difference with the function of performing precise lineation.3.It is an essential measuring tool in machine manufacturing.
The ideal standardized electric motor base for durable belt drives with electric motors from 37 to 200 kW (frame 250 M to 315 S). This motor bases comes in four different lengths, based on the relevant electric motor size. The pretensioning device could be attached in 11 different positions, enabling to incline the bottom plate according to the ideal working angle. The belt pretension could be continuously settled, equivalent to the belt size and amount. All steel parts are painted with a blue primer.
Electric motor slide bases are used to compensate for vibrations and friction that may lead to either slipping or unnecessary wear upon electric motors and belts. They will permit you to precisely adjust the installed motors lateral position to the millimetre. The life span of the equipment will be maximised, consequently decreasing costs and raising profits.
