Hereinafter, a preferred embodiment of a power transmitting apparatus for a clutchless compressor of the present invention will be described with reference to Figs. 3 to 6 attached hereto.

3 to 5, a power transmission apparatus for a clutchless compressor according to an embodiment of the present invention includes a pulley assembly 10 and a limiter assembly 300. As shown in FIGS.

Here, the pulley assembly 10 is rotated by receiving the driving force of the engine.

The pulley assembly 10 has a hollow cylindrical shape and includes a pulley 11 to which a belt (not shown) driven by an engine is connected to an outer circumferential surface of the pulley assembly 10, a bearing (not shown) 12).

At this time, the bearing 12 serves to support the pulley 11 in a state where the pulley 11 is rotatably installed in the front housing 1 of the compressor.

The limiter assembly 300 is configured to transmit the driving force of the pulley assembly 10 to the driving shaft 2 of the compressor or block the transmission of the driving force when the compressor can not be operated.

The embodiment of the present invention suggests that the limiter assembly 300 is configured to include the body 310, the hub 320, and the slip member 330.

This will be explained in more detail for each configuration.

First, the body 310 forms an outer body of the limiter assembly 300 and is coupled to the outer surface of the pulley 11.

In an embodiment of the present invention, the body 310 includes an outer ring 311, an inner ring 312, and a buffer member 313.

The outer ring 311 is formed as an outer ring of the outer body of the body 310 and is formed in a ring shape with its inner side opened. The outer ring 311 is in close contact with the outer surface of the pulley 11, A fastening end 314 having a plurality of fastening holes 314a is bent outwardly.

The inner ring 312 is an inner body of the body 310. The inner ring 312 is spaced apart from the outer ring 311 at an inner portion of the outer ring 311, Hole 312a.

The cushioning member 313 is a mold having a damping force that is molded between the outer ring 311 and the inner ring 312. The cushioning member 313 absorbs the impact of the torque change transmitted from the drive shaft 2 of the compressor . That is, the damping force provided by the cushioning member 313 can damp the weak load transmitted at the initial stage of the operation of the compressor or instantaneously.

In addition, the buffer member 313 may be formed of a rubber material so that damping can be smoothly performed with respect to the rotation direction side of the limiter assembly 300.

Although not shown as an embodiment, the body 310 forming the limiter assembly 300 is formed by a combination of the above three configurations (outer ring and inner ring and buffer member) .

The hub 320 includes a coupling end 321 and a lid end 322. The hub 320 transmits the driving force of the engine provided from the pulley 11 to the drive shaft 2 of the compressor.

The coupling end 321 is a portion through which the installation hole 312a of the inner ring 312 constituting the body 310 is coupled and has a cylindrical structure such that the drive shaft 2 can be received therein. And a serration 321a is formed on the inner circumferential surface thereof so as to engage with the drive shaft 2 to transmit power.

The cover end 322 is a portion for preventing the excessive penetration of the coupling end 321 through the installation hole 312a in the process of coupling the coupling end 321 to the installation hole 312a, .

A coupling hole 322a is formed at the center of the cover end 322 so that when the drive shaft 2 of the compressor is received in the coupling end 321, 2 can be bolted together. This bolting engagement structure prevents undesired axial flow or departure of the drive shaft 2.

The slip member 330 transmits the driving force of the body 310 constituting the limiter assembly 300 to the hub 320. When the excessive torque is supplied from the hub 320 to the slip member 330, The power transmission between the hub 320 and the body 310 is interrupted while slipping between the hub 320 and the body 310.

That is, an overload generated during the compression operation of the compressor (for example, an overload generated due to excessive refrigerant compression) is provided to the engine through the limiter assembly 300 and the pulley 11 to damage the engine However, in this case, the slip member 330 slips between the hub 320 and the body 310 so that the overload of the engine can be prevented. Of course, when the slip member 330 is provided to the body portion 310 through the hub 320, not only when the overload provided from the hub 320 is reversely provided, but also when the driving force due to the instantaneous excessive rotation of the engine is provided to the body portion 310 The power transmission between the hub 320 and the body 310 can be temporarily interrupted while slipping between the hub 320 and the body 310.

The slip member 330 is formed between the inner peripheral surface of the installation hole 312a of the inner ring 312 forming the body 310 of the limiter assembly 300 and the outer peripheral surface of the coupling end 321 of the hub 320 corresponding thereto A ring-shaped body 331 having a ring shape surrounding the outer peripheral surface of the coupling end 321 of the hub 320 as shown in FIG. 6, and a ring-shaped body 331 formed on the outer peripheral surface of the ring- And an elastic protrusion 332.

More specifically, the ring-shaped body 331 is formed so that one end thereof is cut, thereby facilitating the installation of the slip member 330 and facilitating the setting of the load.

The elastic projections 332 are provided to provide an elastic restoring force so that the coupling end 321 of the hub 320 is inserted into the installation hole 312a of the inner ring 312 constituting the body 310 The hub 320 is press-fitted between the coupling end 321 and the attachment hole 312a to smoothly provide the driving force of the body 310 to the hub 320, When the overload is provided in the opposite direction, additional compression deformation is performed to cause the slip with the body 310 to occur.

The plurality of elastic protrusions 332 are provided along the circumferential direction of the ring-shaped body 331 and spaced apart from each other with a predetermined space therebetween, So that a stable elastic restoring force can be provided to the entire surface area.

Particularly, each of the elastic protrusions 332 protrudes toward at least one of the outer peripheral surface of the coupling end 321 of the hub 320 or the inner peripheral surface of the installation hole 312a of the body portion 310 , And the spacing distance and the protrusion height between the elastic protrusions 332 are designed to be different according to the set torque for slip. That is, when the torque exceeding the set torque is provided, the slip of the hub 320 by the slip member 330 or the slip of the body 310 can be performed.

In the embodiment of the present invention, a metal insert ring 340 is fixedly coupled to the inner circumferential surface of the mounting hole 312a formed in the body 310, and the slip member 330 is inserted into the insert ring 340 And is press-fitted between the inner circumferential surface and the outer circumferential surface of the coupling end 321 constituting the hub 320. FIG.

In other words, when the body 310 forming the limiter assembly 300 is formed to have a thickness corresponding to the width of the slip member 330, it is considered that an increase in the overall weight and an increase in the manufacturing cost are caused. It is possible to minimize the thickness of the insert 310 and to secure a sufficient engagement with the hub 320 through the additional provision of the insert ring 340 and sufficient securing of the contact area of the slip member 330 will be.

The insert ring 340 is made of a metal material, so that the insert ring 340 can be stably coupled with the hub 320, but is not easily damaged. At this time, the insert ring 340 may be integrally formed with the inner ring 312 forming the body 310 through an insert injection.

Considering that the insert ring 340 and the body part 310 are susceptible to dissimilar metal contact corrosion, that is, galvanic corrision due to a potential difference caused by different materials between the insert ring 340 and the body part 310 A coating layer (not shown) is preferably formed on the outer surface of the insert ring 340, and the coating layer is formed by electrodeposition or plating.

In the embodiment of the present invention, a receiving groove 321b for receiving the slip member 330 is formed in the outer peripheral surface of the coupling end 321 of the hub 320 so that the slip member 330 is inserted into the coupling end 321) or in the axial direction of the installation hole 312a can be prevented. That is, the slip member 330 can be accommodated in the receiving groove 321b of a predetermined width, so that in the course of installing the coupling end 321 of the hub 320 through the insert ring 340, So that the slip member 330 can be prevented from being displaced from the fixed position and moved in the axial direction. Of course, the receiving groove 321b may be formed so as to be recessed on the inner circumferential surface of the insert ring 340, though not shown.

In the following, the operation of the power transmitting apparatus for a clutchless compressor according to the above-described embodiment of the present invention on the limiter assembly 300 will be described in more detail.

First, when the engine is driven, the driving force of the engine is supplied to the pulley 11, and the driving force thus provided is transmitted to the outer ring 311 constituting the body portion 310 of the limiter assembly 300 coupled to the pulley 11 To the buffering member 313 and the inner ring 312 and then to the drive shaft 2 of the compressor through the hub 320 fixed in the insert ring 340. [

Therefore, the compression operation of the compressor according to the drive of the drive shaft 2 proceeds.

On the other hand, during the compression operation of the compressor 1 described above, a load greater than a set value may be generated, or the rotation of the drive shaft 2 due to the damage of the compressor 1 may be suddenly stopped. In this case, regardless of the stop of the rotation of the driving shaft 2, the pulley 11 may include a hub 320 coupled to the driving shaft 2 and a hub 320 coupled to the driving shaft 2, Is fixed is provided with a fixation force due to the rotation stop.

However, considering that the slip member 330 is provided between the coupling portion between the hub 320 and the insert ring 340, the hub 320 and the insert ring 340 are slipped with each other, Lt; / RTI >

That is, the overload provided to the hub 320 is transmitted to each of the elastic protrusions 332 constituting the slip member 330 prior to being transmitted to the insert ring 340, and each of the elastic protrusions 332 is overloaded The hub 320 is slipped from the insert ring 340 and the transmission of power is interrupted for a predetermined period of time due to compression deformation of the torque exceeding the set torque.

After the overload is eliminated, the elastic protrusions 332 of the slip member 330 are restored to their original state again, so that the hub 320 and the insert ring 340 are press- So that power transmission between them can be smoothly performed.

Therefore, regardless of the hub 320 to which the driving shaft 2 is coupled, the pulley 11 is continuously rotated by the driving force of the engine, thereby preventing the engine from being damaged.

Meanwhile, the slip member 330 of the power transmitting apparatus for the clutchless compressor according to the embodiment of the present invention is not limited to being provided only to the limiter assembly 300 of the above-described embodiment.

For example, the slip member 330 may be provided between the limiter assembly 32 and the hub 33 in the conventional limiter assembly 30. At this time, the rupture structure of the limiter 32 is provided with a double safety structure in which the slip member 330 breaks when the slip can not be smoothly performed.

As described above, the power transmission device for a clutchless compressor according to the present invention has an advantage that the limiter assembly 300 having the slip member 330 is applied, thereby preventing the parts from being damaged and being continuously used.

In addition, the riveting operation can be omitted, and the cost can be reduced by reducing the number of parts and the process.
