Description

LOAD TEST EQUIPMENT OF MOTOR REDUCTION GEAR WITH UP AND DOWN PART}

The present invention relates to a load test apparatus for testing a load of a motor generated by a reducer, and more particularly, by connecting and driving a motor, a reducer, and a brake to test a load of a motor generated by a retarder. In addition, the lower part of the motor seat to which the motor is seated, the lifting control part for lifting and lowering the motor seat part is further configured so that the height of the motor seat can be adjusted and used according to the size and height of the speed reducer to be tested. It relates to a load test device provided with a lift control unit that can improve the.

In general, most of the prime mover or industrial equipment is used a motor that generates a driving force, such a motor is provided with a plurality of devices that are operated by using a motor, in which case the motor may use the rotational force directly, but most In this case, the torque from the motor is converted into a moderately reduced torque through the reducer.

In the conventional motor speed reducer, the worm shaft rotated by the motor and the worm wheel of the first gear of the drive shaft are geared together, and a single shaft small gear formed integrally with the worm wheel is geared with one side second gear. The interlocking shaft is decelerated and driven, and the third major gear fixed to the driving shaft is geared to the second small gear of the interlocking shaft so that the drive shaft is decelerated again and driven to rotate.

Therefore, the rotational driving force of the motor is to rotate the drive shaft in a decelerated state by cohesion of the gears of the first gear, the second gear, the second gear and the third gear. Accumulated load is accumulated in the engagement part, and accumulated impact load is concentrated on gears of the reducer, resulting in a breakdown of the gear, resulting in shortening of the life of the gear, and also shortening the service life of the motor due to the load. Will have

Therefore, there is an urgent need for speed reducer test apparatuses for testing the load applied to the gears engaged with the motor.

In other words, by measuring the load received by the motor and the reducer according to the rotation difference of the reducer rotated according to the capacity of the motor, a load test that can identify and prevent the life time or failure rate of the reducer in accordance with the capacity of the motor in advance (load test The device is urgently needed.

Of course, such a load test device may be configured as a simple device for testing the load applied to the motor by the rotation difference of the reducer by connecting the drive shaft of the reducer to the motor shaft and setting the rotation time of the motor. Considering that they are manufactured differently, there is a problem in that a motor having a motor shaft corresponding to the drive shaft of the reducer must be separately provided. If such a motor is not provided, the work of adjusting the height by connecting the motor shaft and the drive shaft of the reducer is required. Since this is not easy, problems such as the separation of the motor and the reducer from each other during the test are occurring.

Looking at the motor overload test apparatus of the prior art, the load test apparatus of the washing machine patent application No. 10-2004-0056664 has been devised, as can be seen by the claims of the published publication, in a washing machine having a clutch motor A key input unit for inputting a manufacturer's request command, a control unit for selectively controlling an existing load test mode or a short load test mode according to whether or not a product test mode is input when a load test command is input through the key input unit; And a display unit for controlling the driving of the clutch motor and other loads according to the control signal of the display unit, and a display unit for displaying the operation state of the washing and dehydration mode according to the control signal of the controller.

Therefore, if the operation test is performed only with the PCB assembly without changing the mode of the clutch motor during the product load test, it is expected to reduce the time required for testing by operating the clutch motor according to the execution of the short load test mode. Doing.

However, since such a test apparatus is limited to only a motor of a washing machine, there is a problem in that it is generally insufficient or insufficient to test a load generated by a rotation difference between various motors and reducers according to types.

In addition, the prior art is difficult to match the height due to the height difference between the reducer and the motor, and the motor and the reducer are not firmly supported, there is a problem that is separated from each other during the test.
