Abstract
The invention belongs to the technical field of testing control equipment and relates to a motor bearing test bed. A spindle box is composed of a lower box and an upper box connected together; a lower bearing block is connected with a base, and coaxiality with a transmission shaft portion is guaranteed; a spindle is connected with the transmission shaft portion through a coupling; a supporting bearing is fixed in a loading bearing block; a stopper is disposed within the lower box and prevents rotation of the loading bearing block during running; the stopper is fixedly connected to an end cover through bolts; the stopper can prevent rotation of the loading bearing block during force loading. The motor bearing test bed has the advantages that service state of a motor bearing can be really simulated, the size range of a test bearing and speed range thereof are wide, automatic loading and automatic detecting are allowed in the whole process, and test data are true and reliable.
Description
technical fieldmotor bearings testing table, belongs to detection control apparatus technical field.
background technologybe the numerical value that theory calculate obtains in the serviceable life of motor bearings, the vibration values of motor bearings, temperature rise value are also detect single bearing.There is very big error in these numerical value and motor bearings actual condition, can not provide Data support accurately and reliably for product design.
summary of the inventionin view of the defect that prior art exists, the object of this invention is to provide a kind of motor bearings testing table, intuitively can reflect the actual condition of bearing, for designer provides life-span, vibration, temperature rise data accurately and reliably, thus product is made evaluate accurately, guarantee the q&r that bearing products dispatches from the factory.
For achieving the above object, the technology used in the present invention solution is: motor bearings testing table, and main spindle box body is connected and composed by nowel and top box; Step is connected with base, ensures concentric with shaft portion; Main shaft is connected with shaft portion by shaft coupling; The mounting means of measured bearing is identical with real electrical machinery bearing mounting means, and tested cylinder roller bearing, tested deep groove ball bearing, bearing capacity bearing, bearing capacity bearing are fixedly mounted on main shaft by the shaft shoulder, dismounting cover, corresponding spacer and gland, gland; Measured bearing is fixedly mounted in main spindle box body by two ends end cap after loading bearing seat, bearing seat; Top box, bearing seat, the bearing seat circumference in measured bearing panel height center along axis dimension punching, vibration transducer, temperature sensor by the hole on bearing seat can direct detection on the outer ring of measured bearing; By to main shaft stressed mode model rotor weight, plus-pressure assembly is fixedly mounted on top box by seat; Hydraulic jack connects pull pressure sensor, polishing head by connector; Bearing capacity bearing, is fixedly mounted in load bearings seat, has scotch in nowel, and when preventing work, load bearings seat rotates; Load bearings seat top is fixedly connected with pressure block; During loading, polishing head moves downward compression pressure block, is used in by masterpiece on main shaft; Bearing capacity bearing inner race is fixed on main shaft, and outer ring is arranged in load bearings seat, end cap; Load bearings base rear end and end cap leave gap, ensure that the radial force loaded all acts on main shaft; Scotch is bolted to connection on end cap, and when scotch can prevent loading force, load bearings seat rotates.
Motor bearings testing table, its beneficial effect is: can the applying working condition of real simulation motor bearings, and test bearing range of size, the range of speeds are large, can realize whole-process automatic and load, automatically detect.Test figure is true, reliable.
