Abstract
The invention discloses a dedicated high-speed motor for a powder body, which comprises a motor shaft (1) and a motor flange (4) on which a plurality of risers (5) are arranged, and is characterized in that: the front end of the motor shaft (1) is supported by two deep groove ball bearings (7), and is sealed with a sealing cover (8), and the back end of the motor shaft (1) is supported by a single cylindrical roller bearing (9), and also is sealed with a sealing cover (8); and meanwhile, coupling aluminum wind blades (10) are arranged at the tail part of the motor shaft (1) to cool the motor, and six risers (5) are arranged on the motor flange (4). The back bearing provided by the invention adopts the single cylindrical roller bearing (9) which can bear a large radial load; the front of the motor shaft (1) adopts the two deep groove ball bearings (7) which can reduce a load borne by a single bearing; the used sealing covers reduce the impact of the load and also plays a dustproof role; and the used coupling aluminum wind blades avoid the impact of motor shaft vibration on the motor, and improves the reliability of cooling work of the motor.
Description
Technical field
The present invention relates to a kind of high-speed electric expreess locomotive that equipment such as powder ultra micro comminution by gas stream and classification adopt that is used for.
Background technology
Be used for high-speed electric expreess locomotive on the equipment such as powder ultra micro comminution by gas stream and classification at present like Fig. 3, shown in 4;, equipment can quicken when pulverizing the high rigidity material at a high speed pulverizing the centrifugal wheel wearing and tearing; Cause centrifugal wheel dynamic balance variation, amount of unbalance increases, and causes the motor complete machine oscillation; When just beginning the centrifugal wheel amount of unbalance hour; At first cause motor shaft (1) vibration, centrifugal wheel can drag axle and form the lever form with fore bearing (2), rear bearing (3), and active force mainly concentrates on the rear bearing (3); Motor shaft this moment (1) slowly becomes matched in clearance (bearing outer ring is compacted) with fore bearing (2) inner ring; When increase along with the centrifugal wheel amount of unbalance; The motor oscillating aggravation causes fore bearing (2) to damage, three lugs (5) fracture or damage that motor flange (4) is connected with support; Last motor complete machine damages, so that the equipment motor that just need more renew within a short period of time, has influenced the machine life of powder equipment; Motor adopts independent axes flow fan (6) that motor is dispelled the heat at present simultaneously, and axial flow blower damages under the motor oscillating influence easily, thereby causes and can't dispel the heat.
Summary of the invention
In order to solve the problem of damaging easily under the vibration situation that above-mentioned motor bearings and blower fan produce in the motor high speed rotating.The present invention provides a kind of powder specialized high-speed motor; Technical scheme of the present invention is: include a motor shaft, a motor flange; Several lugs are arranged on the motor flange, it is characterized in that: the front end of motor shaft adopts two deep groove ball bearings to support, and seals with seal cover; The rear end of motor shaft adopts single cylinder roller bearing to support, and also seals with seal cover; Simultaneously at the afterbody of motor shaft shaft coupling aluminium air blade being housed dispels the heat to motor.
As further qualification, the quantity of the lug on the described motor flange is six.
The present invention adopts the beneficial effect of above technical scheme to be: when equipment pulverize at a high speed make centrifugal wheel wearing and tearing make the dynamic balance variation, when motor shaft begins to vibrate, rear bearing adopts cylinder roller bearing, can carry big radial load and can not damage; Increase along with the centrifugal wheel amount of unbalance; It is big that motor oscillating becomes; This moment, motor shaft and fore bearing inner ring slowly became matched in clearance; Two deep groove ball bearings are adopted in front at motor shaft, reduce the load that single bearing bears, thereby have avoided causing damage of bearings in the radial load increase under centrifugal wheel rotates of fore bearing under the high speed conditions; With seal cover bearing inner race is compressed, it is uneven and the load impacting that causes has been protected motor bearings also to have reduced gap between motor shaft and the bearing greatly again, in addition, also can motor be protected when powder has when leakage seal cover; Six lugs that adopted double than the quantity of the lug on the existing motor, have played reinforcement effect better; Adopt shaft coupling aluminium air blade that motor is dispelled the heat simultaneously, replaced existing independent axes flow fan, avoided it to receive the influence of motor shaft vibration, improved the reliability of motor radiating work.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is a left view of the present invention;
Fig. 3 is the front view of existing motor;
Fig. 4 is the left view of existing motor.
Among the figure, 1 motor shaft, 2 fore bearings, 3 rear bearings, 4 motor flanges, 5 lugs, 6 independent axes flow fans, 7 deep groove ball bearings, 8 seal covers, 9 cylinder roller bearings, 10 shaft coupling aluminium air blades.
Embodiment
Like Fig. 1, shown in 2; The present invention includes a motor shaft 1, a motor flange 4; Several lugs 5 are arranged on the motor flange 4, and the front end of motor shaft 1 adopts two deep groove ball bearings 7 to support, and seals with seal cover 8; The rear end of motor shaft 1 adopts single cylinder roller bearing 9 to support, and also seals with seal cover 8; Simultaneously at the afterbody of motor shaft 1 10 pairs of motors of shaft coupling aluminium air blade being housed dispels the heat; The quantity of the lug 5 on the described motor flange 4 is six.
When equipment pulverize at a high speed make centrifugal wheel wearing and tearing make the dynamic balance variation, when motor shaft begins to vibrate, rear bearing adopts cylinder roller bearing, can carry big radial load and can not damage; Increase along with the centrifugal wheel amount of unbalance; It is big that motor oscillating becomes; This moment, motor shaft 1 slowly became matched in clearance with deep groove ball bearing 7 inner rings; Two deep groove ball bearings 7 are adopted in front at motor shaft 1, reduce the load that single bearing bears, thereby have avoided causing damage of bearings in the radial load increase under centrifugal wheel rotates of fore bearing under the high speed conditions; Use seal cover 8 that bearing 7,9 inner rings are compressed again, it is uneven and the load impacting that causes has been protected motor bearings also to have reduced gap between motor shaft and the bearing greatly, in addition, also can motor be protected when powder has when leakage seal cover 8; Six lugs 5 that adopted double than the quantity of the lug on the existing motor, have played reinforcement effect better; Adopt 10 pairs of motors of shaft coupling aluminium air blade to dispel the heat simultaneously, replaced existing independent axes flow fan 6, avoided it to receive the influence of motor shaft vibration, improved the reliability of motor radiating work.
Above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as the technology contents essence of being made according to the disclosed technical scheme of this patent is identical or any change or the modification that are equal to, all fall into the scope that this patent comprises.
