Abstract
The utility model relates to the field of clamps, in particular to a clamp for measuring work of an external rotor motor. The clamp mainly comprises a motor shaft support and an external rotor connecting base. The motor shaft support is composed of a support body, a left flange and a right flange. An elongated slot is formed in the support body. A screw is arranged at the bottom of the support body. A motor shaft sequentially penetrates through the left flange, the support body and the right flange and then is placed on the elongated slot of the support body. Jackscrews which can limit the motor shaft from rotating are arranged on the side wall of the left flange and the side wall of the right flange, and the left flange and the right flange are connected with the support body. A stepped circular hole is formed in one end face of the external rotor connecting base, and a connecting shaft is arranged on the other side end face of the external rotor connecting base. The motor shaft is installed into an inner bearing ring, an outer bearing ring is installed into the circular hole of the external rotor connecting base, the external rotor connecting base is connected with a motor external rotor bolt, and the connecting shaft of the external rotor connecting base is connected with a dynamometer input shaft through a coupler. The clamp is simple and practical in structure, reliable in connection, and suitable for measuring work of the external rotor motor.
Description
Technical field
The utility model relates to special fixture field, especially relates to a kind ofly for clamping outer motor, being convenient to testing of electric motors power, the isoparametric special fixture of rotating speed.
Background technology
Motor needs to test its performance parameter (comprising the parameters such as rotating speed, torque, input power, power output, efficiency) before use, this just need to use dynamometer machine, dynamometer machine needs to be equipped with the parts such as controller, dynamometer machine, fixture in use, wherein fixture is used for fixing motor stator part, and rotor is connected with shaft coupling with the power shaft of dynamometer machine.In general, existing motor adopts the structure of external stator, internal rotor conventionally, so the fixture of existing dynamometer machine is also for this class design of electrical motor, and some special machines, as ceiling fan, wheel hub motor etc., according to use occasion, need be designed to the structure of outer rotor, inner stator, this class motor need to use dynamometer machine testing of electric motors parameter, uses existing fixture to clamp obviously just improper, is therefore necessary to design a kind of special fixture.
Summary of the invention
For addressing the above problem, the purpose of this utility model be to provide a kind of simple in structure, clamp external rotor electric machine measurement of power fixture reliably.
For reaching above-mentioned purpose, the utility model adopts following scheme: a kind of external rotor electric machine measurement of power fixture, its difference is: mainly include motor shaft bearing, outer rotor Connection Block, motor shaft bearing is comprised of bearing body, left flange and right flange, on bearing body, offer elongated slot, bearing body bottom arranges screw, motor shaft is placed on bearing body elongated slot through after left flange, bearing body and right flange successively, left flange and right flange sidewall are provided with the jackscrew can limiting motor axle rotating, and left flange is connected with bearing body with right flange; One end face of outer rotor Connection Block has stairstepping circular hole, opposite side end face is provided with connecting axle, motor shaft packs bearing inner race into, bearing outer ring packs in the circular hole of outer rotor Connection Block, outer rotor Connection Block and motor outer rotor bolt-connection, the connecting axle of outer rotor Connection Block connects with dynamometer machine power shaft by shaft coupling.
The utility model is simple and practical, connects reliably, and applicable external rotor electric machine measurement of power is used.
