Background technology
Motor is before dispatching from the factory, its electrical property need to be tested, existing method of testing is as generator operation using same model motor, drags tested motor running, and the simulation of the Overlay of the motor various damping forces in true environment is to be simulated by the size of shaft clip frictional force. This method of testing there is problems in that owing to motor has vibration at rotation process axis, the frictional force produced between anchor ear and axle is unstable, have influence on the true simulation of the operating various damping forces of motor, thus causing the accuracy of motor electric performance test, needing repeatedly to adjust the degree of tightness of anchor ear, workload is bigger. Additionally, due to the time longer (being generally 7 hours) of test every time, the frictional force of anchor ear can cause that the axle temperature of tested motor raises, and on axle, the bearing heat damage of assembling is serious, and the axle of anchor ear and tested motor can serious wear.
Summary of the invention
The invention provides a kind of motor electric performance testing device, solve in motor motor shaft and the serious problem of bearing damage thereof in electric performance test.
The present invention solves above technical problem by the following technical programs:
A kind of motor electric performance testing device, including tested motor and dragging motor, the output shaft of tested motor and dragging motor are linked together by shaft coupling, the output shaft of dragging motor is provided with insulation sleeve, insulation sleeve is to be fixed together by the output shaft of insulation sleeve jackscrew Yu dragging motor, insulation sleeve is socketed with endless metal dish, endless metal dish is fixed together by attachment screw and insulation sleeve, the housing of dragging motor is provided with L-type cantilever shalving, outboard end at L-type cantilever shalving is provided with crane and passes through U-type groove, it is provided with prelocalization screw by U-type groove one sidewall at crane, prelocalization screw is provided with prelocalization hollow bolt, at crane by positioning screw hole after being provided with on another sidewall of U-type groove, rear positioning screw hole positions after being provided with hollow bolt, between prelocalization hollow bolt and rear location hollow bolt, activity is plugged with gear and supports axle, support at gear and axle is fixedly installed gear, it is provided with gear rack elevating plate by U-type groove at crane, gear rack elevating plate is provided with the tooth bar that vertically vertical direction is arranged, rack and pinion meshes together, the bottom of gear rack elevating plate is provided with U-shaped groove, a sidewall is provided with N pole permanent-magnet steel in the groove of U-shaped groove, another medial wall is provided with S pole permanent-magnet steel in the groove of U-shaped groove, endless metal disk activity is arranged between N pole permanent-magnet steel and S pole permanent-magnet steel.
The top end face of prelocalization hollow bolt and the front end face movable top of gear are connected together, and the rear end face movable top of the rear top end face and gear positioning hollow bolt is connected together.
Present invention, avoiding the test abrasion to motor shaft, rotational speed regulation is convenient, and outer shaft active force is steady. Whole process of the test only need to regulate once, just can complete whole experimental project, significantly reduce labor intensity, owing to adopting the eddy current acting in electromagnetic force, endless metal hair updo heat, between endless metal dish and axle, there is a nonmetallic insulation sleeve, heater does not directly contact with axle, axle temperature rises relatively low, and the damage of bearing is less, is effectively reduced because of the too high damage to bearing of temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is that the crane of the present invention is by location hollow bolt in U-type groove 9, fiting relation figure between gear 19 and tooth bar 15.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
A kind of motor electric performance testing device, including tested motor 1 and dragging motor 2, the output shaft of tested motor 1 is linked together by shaft coupling 3 with dragging motor 2, the output shaft of dragging motor 2 is provided with insulation sleeve 4, insulation sleeve 4 is to be fixed together by the output shaft of insulation sleeve jackscrew 5 with dragging motor 2, insulation sleeve 4 is socketed with endless metal dish 6, endless metal dish 6 is fixed together by attachment screw 7 and insulation sleeve 4, the housing of dragging motor 2 is provided with L-type cantilever shalving 8, outboard end at L-type cantilever shalving 8 is provided with crane by U-type groove 9, it is provided with prelocalization screw 10 by U-type groove 9 one sidewall at crane, prelocalization screw 10 is provided with prelocalization hollow bolt 11, at crane by positioning screw hole after being provided with on another sidewall of U-type groove 9, rear positioning screw hole positions after being provided with hollow bolt 12, between prelocalization hollow bolt 11 and rear location hollow bolt 12, activity is plugged with gear and supports axle 13, support at gear and axle 13 is fixedly installed gear 19, it is provided with gear rack elevating plate 14 by U-type groove 9 at crane, gear rack elevating plate 14 is provided with the tooth bar 15 that vertically vertical direction is arranged, tooth bar 15 and gear 19 mesh together, U-shaped groove 16 it is provided with in the bottom of gear rack elevating plate 14, in the groove of U-shaped groove 16, a sidewall is provided with N pole permanent-magnet steel 17, in the groove of U-shaped groove 16, another medial wall is provided with S pole permanent-magnet steel 18, endless metal dish 6 is movably arranged between N pole permanent-magnet steel 17 and S pole permanent-magnet steel 18.
