Description
Technical field
The present invention relates to a kind of driving mechanism, more particularly, relate to a kind of high speed drive that is used for generator performance and endurance test.
Background technique
At present, the high speed drive of carrying out generally adopting on the test stand of generator performance and endurance test roughly has two classes: a class is to adopt variable-frequency motor to realize two-stage transmission raising speed by V-type band or poly Vbelt, directly drives the rotation of generator belt wheel by belt.Another kind of is with adopting high-speed electric expreess locomotive, by the locking nut of coupling drive transmission shaft connection generator, thereby driving the generator shaft rotation.The former shortcoming is that rotating speed is lower, can only reach 8000～10000 rev/mins at a high speed, can't satisfy test requirements document.Though and the latter slightly improves on rotating speed, the highlyest at a high speed also can only reach 10000 rev/mins, easily generate heat but also have bearing, thereby bearing is fragile shortcoming such as vibration equipment is big, noise is big.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can increase substantially rotating speed, and generator performance that vibration equipment is little, noise is little and endurance test high speed drive.
High speed drive provided by the invention comprises motor, belt drive unit, transmission shaft, bearing bracket stand, coupling and shaft coupling, belt drive unit connects an end and the motor of transmission shaft, coupling connects the other end of transmission shaft and an end of shaft coupling, bearing bracket stand is installed on the transmission shaft, and described bearing bracket stand comprises end cap, internal frame, outrigger, bearing and the oil deflector of a side that is installed in the close bearing bracket stand middle part of bearing, the top and bottom of end cap comprise filler opening and oil outlet respectively, comprise in the internal frame first passage that is communicated to oil deflector and with the second channel of the internal communication of bearing bracket stand, comprise third channel that is communicated with the first passage in filler opening and the internal frame and the four-way that is communicated with the second channel in oil outlet and the internal frame in the end cap.
High speed drive provided by the invention not only can increase substantially rotating speed by belt transmission is combined with shaft drive, and can reduce the vibration of equipment, reduces the noise of equipment.In addition, by grease channel and cooling water passage are set in bearing bracket stand, can guarantee that not only bearing and whole bearing bracket stand are lubricated good, and a large amount of heats that produce can take away the equipment high speed rotating time, help the heat radiation of equipment, thereby can reduce the damage of equipment, prolong the working life of equipment, guarantee the good operation of high speed drive.
