Abstract
A test device for an automobile generator and a belt wheel of a generator mainly includes a motor, a high frequency speed change mechanism and a generator. The test device is characterized in that the high frequency speed change mechanism mainly includes a swing rod, movable pulleys and fixed pulleys; the movable pulleys are disposed on the two ends of the swing rod respectively; two fixed pulleys are disposed above and below each movable pulley respectively so that a belt can form a wrap angle less than 90 degrees when passing through the movable pulleys; the motor drives the belt of the generator to pass through the two movable pulleys and the four fixed pulleys; and when the swing rod moves left and right, the belt is pulled upwards and downwards to and fro, so a speed difference is formed. The test device is reliable, and has a simple structure. The motor only needs to run at the uniform speed, so the current of the motor is less than one fifth of the current at the high-frequency variable speed, and the energy consumption is greatly reduced. Moreover, the service life of the motor is greatly prolonged.
Description
Technical field
The present invention relates to a kind of testing equipment, especially relate to a kind of testing equipment of automobile current generator.
Background technology
Automobile current generator provides power to generate electricity by internal combustion engine, and internal combustion engine is due to its stroke of piston operating characteristic, and its velocity characteristic produced are not at the uniform velocity, but the awave velocity characteristic of small-pulse effect.Automobile current generator and belt wheel thereof are ensure performance when dispatching from the factory reliable, need sample and do working condition tests; Its testing requirements 1 is: testing machine drive electrical generators forwards 2882 turns to 26.7 high frequency speed changes p.s. from per minute 1920, and its principle is the state of imitative internal combustion engine when idle running; Testing requirements 2 is: testing machine drive electrical generators forwards 9135 turns to 100 high frequency speed changes p.s. from per minute 8865, and its principle is the state of imitative internal combustion engine when normal traveling; Testing requirements 3 is: testing machine drive electrical generators 15000 turns of uniform motion per minute, and its requirement is the state of imitative internal combustion engine high-speed cruising.This testing equipment is all that external business men application servomotor progressive die intends this operating condition of test at present, because it requires that motor is with 26.7 times and 100 high frequency speed changes per second, although its velocity contrast is not very large, but the high accuracy to data when so high speed change frequency and test, the rate curve of its each speed change needs highly consistent, so just needs more than 5 times power larger than normal current to carry out instant speedup and deceleration; It is a kind of huge test and injury to motor; All want 1000 hours owing to testing at every turn, its each test all needs power consumption about 40,000 kilowatts; It is also huge injury to the energy.
Summary of the invention
The object of this invention is to provide the testing equipment of a kind of power saving efficient high frequency transmission cars generator and belt wheel thereof.
In order to reach above-mentioned goal of the invention, the technical solution adopted in the present invention is: this device is primarily of motor, high frequency gear, generator composition; It is characterized in that: high frequency gear is primarily of fork, travelling block, fixed pulley composition; It adopts fork two ends to be respectively provided with a travelling block; Each travelling block respectively installs a fixed pulley up and down, makes belt become one to be less than the cornerite of 90 degree by row during travelling block; The belt of motor drive electrical generators is respectively by two travelling block and four fixed pulleys, and fork side-to-side movement will be pulled on back and forth belt and leave behind, thus produces velocity contrast.Fork to-and-fro movement preferred cam mechanism, linkage assembly.
As the further improvement of technique scheme, described fork is arranged on line slideway, makes it run more rectilinearity, thus more synchronous when allowing left and right pulley pull pulley.
The invention has the beneficial effects as follows: structure of the present invention is simple, reliable, and motor only needs motion at the uniform velocity, thus makes its electric current be reduced to less than 1/5th of high frequency speed change, thus significantly reduces energy consumption, and motor life also significantly improves; Fork to-and-fro movement can produce energy consumption, but is small movements due to it, and adopt cam mechanism and linkage assembly time power be also uniform rotation, its energy consumption is not as good as 1/2nd of motor uniform motion.
