Description
Technical field
The present invention relates to high speed drive, particularly relate to a kind of high speed prime mover.
Background technology
Along with modern technologies and expanding economy, the energy-efficient motive force increasingly becoming society.And in universal machine industry, widely used fluid machinery, is also generally developing to high speed direction, and is trying to achieve higher efficiency and performance, the most especially with three-dimensional flow centrifugation technique products such as monopole centrifugal blowers as representative.Current ternary flow technology product, generally requires the rotating speed of nearly 10000 revs/min, could obtain higher efficiency.The commonly used gearbox drive in market and at high speed frequency conversion motor realize the rotating speed of this order of magnitude, but all there is defect.
Gearbox drive is owing to building the gear-box of a canine tooth ratio, often cost is high, complete machine unit price is difficult to control to, consider for commercial cost angle, when product power is less than 75KW, gear-box occupies cost ratio just more than 50%, and when product power is less than 22KW, gear-box cost even rises to nearly 70%, has completely lost economy.
The positions such as the rotor of high-speed induction motor, dispels the heat, bearing are required for redesigning, and industry is relatively costly.And the most unstable, its core reasons are, high-speed electric expreess locomotive, because the restriction of structure, often can only use grease lubrication structure, and grease lubrication is not particularly suited for high-speed drive.
And existing market exists the common centrifugal blower etc. within a large amount of 22KW, it is limited by rotating speed, can only run on the premise of at most 3000 revs/min, it is difficult to produce high performance product.
Therefore, it is badly in need of a kind of low cost, the kind of drive of high stability at present, traditional product is carried out transformation and upgrade.
Summary of the invention
It is an object of the invention to provide a kind of high speed prime mover.
The technical solution used in the present invention is:
High speed prime mover, it is characterized in that: include motor and body, described motor is provided with drivewheel, described body center is provided with main shaft, described main shaft one end connects working machine, the other end is provided with driven pulley, connected by belt between described drivewheel and driven pulley, described internal body main shaft periphery is provided with oil sealing axle sleeve, it is provided with bearing between described oil sealing axle sleeve, described bearing and oil sealing axle sleeve are fixed by locking nut, it is provided with eccentric bearing block between described oil sealing axle sleeve and body, described eccentric bearing block extends to body two ends, described eccentric bearing block periphery is provided with oil seal cover, it is provided with wavy spring between described oil sealing axle sleeve and body, micro-impeller it is provided with between described eccentric bearing block and main shaft, described micro-impeller is provided with fuel feed hole and nozzle opening, described body side is provided with oil return pipe.
It is provided with framework type sealing ring between described oil sealing axle sleeve and locking nut.
The invention have the advantage that regulation belt pulley size, realize the rotating speed within 10000 turns flexibly, using oil lubrication, lubricant effect is preferable, and the lubrication oil circulation injection equipment of indoor design can effectively promote the lubricant effect of lubricating oil, and with low cost.
