Description

Fatigue test installation for spring of starting rod in engine of motorcycle

Technical field

The utility model relates to a kind of fatigue experimental device, relates in particular to the device that the motorcycle engine priming lever spring is carried out torture test.

Background technology

The motorcycle engine priming lever spring is a strength member in the motorcycle engine, if the engine that breaks down just can not start by normal ignition, therefore, must carry out torture test (sampling observation) to priming lever spring before engine dispatches from the factory.At present each model motorcycle engine all requires priming lever spring can normally rebound 10,000 times under the analog operation state before dispatching from the factory and non-fault is just qualified.Traditional experiment (sampling observation) method is to step on the engine start bar that assembled 10,000 times by artificial pin continuously, every day one people's pin step on 300 times just exhausted, finish the torture test of an engine start bar spring, then need continuous pin to step on 8 hours, totally 30 people just can finish, waste time and energy very much, and strength and frequency that everyone pin is stepped on are unlikely, thereby cause test findings inaccurate easily.

The utility model content

Problem to be solved in the utility model provides a kind of replacement manually-operated, can save manpower, increases work efficiency and also can guarantee the reliable fatigue test installation for spring of starting rod in engine of motorcycle of test findings.

For addressing the above problem, fatigue test installation for spring of starting rod in engine of motorcycle described in the utility model, motor, reductor, runner bearing, pivoted arm bearing and engine stationary fixture are installed on worktable, wherein, the output shaft of motor and the input shaft of reductor link, on the output shaft of reductor small belt pulley is installed, is provided with connecting pin on the end face of small belt pulley, this connecting pin links by lever arm and the revolution counter that is installed on the worktable; By Bearing Installation big belt pulley is arranged on the runner bearing, on the end face of big belt pulley, be fixed with shifting block, link by belt between big belt pulley and the small belt pulley; The pivoted arm bearing is between runner bearing and engine stationary fixture, on the pivoted arm bearing pivoted arm is installed, the shaft center line of pivoted arm is with respect to the center off-centre of big belt pulley, one end of pivoted arm is fixed with axle, by bearing holder (housing, cover) axle sleeve is housed on the axle, axle sleeve contacts with shifting block on the big belt pulley end face, and the other end of pivoted arm is provided with the starting shaft adapter sleeve.

The engine stationary fixture is used for fixing the engine that primer spring is installed in the utility model.Pivoted arm is equivalent to the motorcycle engine starting handle, and the adapter sleeve of pivoted arm one end stretches in the engine, and links by female spline and engine start axle, the pedal that the axle of the pivoted arm other end and shaft sleeve part branch are equivalent to starting handle.Revolution counter is used for calculating the revolution of small belt pulley, promptly measures the bounce-back number of times of engine start bar spring indirectly.The output of motor is slowed down for the first time through reductor and is transferred torque on the small belt pulley, after slowing down the second time between small belt pulley and the big belt pulley, be delivered on the big belt pulley again, big belt pulley drives shifting block and rotates (revolution) around the center of big belt pulley, and shifting block rotates by the axle sleeve drive pivoted arm of contact with it again.Because the shaft center line of pivoted arm is with respect to the center off-centre of big belt pulley, therefore after shifting block turns to certain angle, shifting block disengages with the axle sleeve that is installed in pivoted arm one end, the pivoted arm same initial position that under the effect of primer spring on the starting shaft, rebounds, the angle that pivoted arm need rotate is identical with the angle that the engine start bar need rotate, and this angle value (being about 135 °) is by how many common decisions with respect to eccentricity value and the shifting block and the axle sleeve surface of contact at big belt pulley center of the shaft center line of pivoted arm.When big belt pulley drive shifting block passed through the axle sleeve of pivoted arm one end once more, shifting block drove pivoted arm again and does the rotation of equal angular for the second time, and so repeatedly, the numerical value that shows on the revolution counter reflects the number of times that primer spring has rebounded.If primer spring bounce-back number of times reaches setting (being generally 10000) and does not break down, then stand the test.

The beneficial effects of the utility model are: replace manually-operated, can finish the detection of an engine start bar spring in one day, saved manpower, improved work efficiency, and made test findings reliable.
