Description

Load testing device for driving device {apparatus for motor testing}

The present invention relates to a load testing device for a driving device, and more particularly, to a load testing device for a driving device having improved installation convenience and sealing performance.

In general, an inspection chamber is used for environmental tests such as temperature and humidity during performance testing of motors or generators. At this time, the motor or generator is used in various industrial sites, and in order to apply it to an industry that requires high precision, a precise inspection must be performed in the inspection stage.

Here, in the conventional inspection method of a motor or generator, a motor for inspection is prepared, the motor to be inspected is connected to the shaft of the motor for inspection, and a chamber having a space formed therein is moved to the motor to be inspected so that the motor to be inspected is the chamber. Inspection was performed while placed in the interior space.

In this case, the motor for inspection is disposed outside the chamber, and the shaft connected between the motor for inspection and the motor to be inspected is also exposed to the outside. In addition, environmental tests according to constant temperature and humidity were performed while the motor to be inspected was thermally sealed and blocked from the outside by the chamber.

However, the conventional chamber has a problem in that the installation of the inspection motor and the chamber is cumbersome and time-consuming when the inspection target motor is disposed inside and closed. In detail, in the conventional chamber, whenever the motor to be inspected is placed inside the chamber, the shaft between the motor for inspection disposed outside and the motor to be inspected disposed inside the chamber must be inserted and aligned in the hole formed in the chamber every time, so that workability is achieved. There was a problem of this deterioration.

In addition, in order to cover the chamber to the motor to be inspected, it is difficult to block the lower end of the shaft portion of the inspection motor, so that the internal space of the chamber is not completely sealed.

At this time, in the second step, the rotation transmission unit 53 is provided as at least one or more layers of carbon fiber woven body winding, one end of which is on the outer circumferential surface of the first ring unit 51 in the circumferential direction. ) is preferably melt-bonded simultaneously.

Here, in a state in which the thermal press device 200 is heated to a melting temperature or higher for one end of the rotation transmission unit 53 to be melted, one end of the rotation transmission unit 53 is pressed inward in the radial direction to form the first It may be melt-bonded to the outer peripheral surface of the ring portion (51).

Meanwhile, in the third step, the second ring part 52 is spaced apart from the first ring part 51 in the front-rear direction, and the first shaft insertion hole 51a and the second shaft insertion hole 52a are front and back. direction, the other end of the rotation transmission unit 53 is disposed on the outer circumferential surface of the second ring unit 52, and the thermal press device 200 connects the other end of the rotation transmission unit 53 to the second end of the rotation transmission unit 53. The other end of the rotation transmission part 53 is melt-coupled to the second ring part 52 by thermal pressing in the radial direction along the circumferential direction of the second ring part 52 (s30).

Here, in the third step, the thermal press device 200 disposed to surround the radially outer side of the first ring portion 51 is moved to the radially outer side of the second ring portion 52 along the front-rear direction may further include. Of course, in some cases, the first ring part 51 and the second ring part 52 are moved in the front-rear direction without moving the thermal pressing device 200 so that the outer surface of the second ring part 52 is subjected to the thermal pressing. It may also be aligned and moved radially inward of the device 200 .

At this time, in the third step, it is preferable that the other end of the rotation transfer unit 53 is simultaneously melt-bonded to the outer circumferential surface of the second ring unit 52 through the thermo-pressurizing device 200 in the circumferential direction.

Here, in a state in which the thermal press device 200 is heated to a melting temperature or higher for the other end of the rotation transmission unit 53 to be melted, the other end of the rotation transmission unit 53 is pressed inward in the radial direction to obtain the It may be melt-bonded to the outer peripheral surface of the second ring portion (52).

And, in the third step, the first ring part 51 and the second ring part 52 are spaced apart from each other in the front-rear direction and aligned, the first ring part 51 and the second ring part 52 It is preferable that the separation space (50a) is formed between and inside the rotation transfer part (53) in the radial direction.

As such, in the load test apparatus 100 for a driving device according to the present invention, the first ring part 51 into which the inspection shaft part 11 is inserted, and the rotation shaft 1a of the driving device to be inspected are inserted into the first Since both ends of the rotation transmission unit 53 provided as at least one or more layers of carbon fiber woven body windings capable of organic movement on each outer circumferential surface of the ring portion 51 and the second ring portion 52 spaced apart in the front and rear directions are coupled, the rotational force During transmission, damage to equipment due to misalignment of the shaft is prevented and durability can be improved.

In addition, when the first ring part 51 is rotated, one side of the rotation transmission part 53 is rotated first along the rotation direction and the other side of the rotation transmission part 53 is rotated in a second interlocking state in a twisted state, Torque ripple is corrected and alleviated through an organic motion that transmits the rotational force to the two-ring part 52, so that the accuracy and reliability of the performance data of the driving device to be inspected derived from the environmental test can be remarkably improved.

And, in a state in which at least one layer of carbon fiber woven body wound material is laminated along the radial direction on the outer circumferential surface of the first ring part 51 and the second ring part 52 in correspondence to the maximum allowable value of the transmittable rotational force, the thermal pressurization Through the device 200, it is pressed and heated radially inward along the circumferential direction, so that it is possible to precisely set the torque transmission force to be transmitted by melt-bonding, so that manufacturing precision can be remarkably improved.

In addition, when an external force exceeding the allowable maximum value of the rotational force transmitted from the first ring part 51 to the second ring part 52 acts, the rotation transmission part 53 provided as a winding of the carbon fiber woven body is broken. Accordingly, since the transmission of the rotational force is quickly blocked, damage to the inspection driving unit 10 and the driving device to be inspected is prevented in advance, so that the safety of use can be significantly improved.
