Description
Technical field
The utility model relates to mechanical engineering testing equipment field, especially electric device life test rack.
Background technology
Electric device is when carrying out durability test, owing to requiring electric device at least can bear non-fault, the work operating life test of nearly ten thousand times in GB with certain load in the situation that.Therefore, when carrying out durability test compared with the electric device of high pulling torque, common by the testing equipments such as " brake block ", " magnetic loadings " in the simulation loading test of long-time, multifrequency time can because of equipment temperature rise soon, quick abrasion, intensity be low, the shortcoming such as large that consumes energy is damaged in advance, cause electric device also not damage, " accident " phenomenon that the testing equipment in test electric device life-span has damaged in advance.
Summary of the invention
Problem to be solved in the utility model is to use hydraulic loading mechanism to carry out durability test to electric device, reduces noise and power consumption, and loading efficiency improves, continuously-running work simple to operate, meets the high request durability test with load.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: electric device life test rack, and it comprises electric operator, load maintainer, testing agency, base;
Electric operator comprises electrodynamic element and output shaft;
Load maintainer comprises hydraulic cylinder, Hydraulic Station, transmission shaft, described transmission shaft one end is connected with output shaft, this transmission shaft is tubular shaft, load maintainer also comprises thrust unit, this thrust unit is fixed on base, and thrust unit interior support one feed screw nut, this feed screw nut is connected with the transmission shaft other end, on described feed screw nut, be equipped with the leading screw being mated, described leading screw one end is connected with hydraulic cylinder by joint, this hydraulic cylinder is controlled by Hydraulic Station, and the other end of leading screw gos deep in hollow transmission shaft;
Testing agency comprises the torque sensor being connected with base, and described torque sensor and electrodynamic element are affixed.
Further, described transmission shaft is connected with output shaft dental inlay.
Further, described transmission shaft is connected with feed screw nut dental inlay.
Further, described torque sensor is affixed by flange and electric operator.
Further, base is configured to by propping up, and supports electric operator and load maintainer, and described hydraulic cylinder and Hydraulic Station are placed in base inside.
Advantage and the good effect that the utlity model has are: adopt hydraulic loading device to carry out durability test to electric device, because hydraulic means can bear high moment of torsion, large load, the inferior operating condition of test of multifrequency, and noise is low, low in energy consumption, the plurality of advantages such as temperature rise is slow, loading efficiency is high, continuously-running, stability are high, simple to operate, met the durability test with load, nearly ten thousand times or requirements at the higher level to electric device.

Embodiment
Below in conjunction with accompanying drawing and concrete embodiment, the utility model is further described.
As shown in Fig. 1-3, electric device life test rack, it comprises electric operator, load maintainer, testing agency, base.
Electric operator comprises electrodynamic element 1 and output shaft.
Load maintainer comprises hydraulic cylinder 7, Hydraulic Station, transmission shaft 3, described transmission shaft one end is connected with described output shaft dental inlay, this transmission shaft 3 is tubular shaft, load maintainer also comprises thrust unit 4, this thrust unit is fixed on base 8, and thrust unit 4 interior support one feed screw nuts 9, this feed screw nut is connected with transmission shaft 3 other end dental inlays, on described feed screw nut, be equipped with the leading screw 5 being mated, described leading screw one end is connected with hydraulic cylinder 7 by joint 6, this hydraulic cylinder is controlled by Hydraulic Station, and the other end of leading screw 5 gos deep in hollow transmission shaft 3.
Testing agency comprises the torque sensor 2 being connected with base 8, and described torque sensor and electrodynamic element 1 are affixed by flange.
Base 8 is configured to by propping up, and supports electric operator and load maintainer, and described hydraulic cylinder 7 and Hydraulic Station are placed in base inside.
The present embodiment principle of work: when electrodynamic element starts, output shaft also rotates thereupon, the transmission shaft connecting with output shaft is also synchronizeed rotation, this transmission shaft drives the feed screw nut being connected with its dental inlay to rotate simultaneously, feed screw nut makes leading screw move up and down, when leading screw moves, by Hydraulic Station, controlling hydraulic cylinder operates, now hydraulic cylinder can stop connected leading screw to move, will cause like this electrodynamic element imposed load power, controlled the speed speed that leading screw moves up and down, but now electrodynamic element is still in normal operation, finally cause torque sensor to produce deformation, and then record by torque sensor the load that current electrodynamic element bears.
Now, can to the size of the suffered load of electrodynamic element, regulate by Hydraulic Station, until meet standard regulation, then can carry out to electrodynamic element the durability test of constant load or variable load.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model scope and improvement etc., within all should still belonging to this patent covering scope.
