Description

DESCRIPTION A COMPRESSOR WITH INCREASED LUBRICATION PERFORMANCE This invention is a compressor with an oil suction pipe moving with the crankshaft. It is related to.

In coolers, the cycle of the refrigerant used for cooling is done by a compressor. is provided with. Especially in compressors used in coolers, moving An oil suction pipe in the process of delivering oil to the bearings formed by the surfaces accomplished by. The lubrication process inside the compressor By absorbing the oil from the bottom of the housing, the bearings that need to be lubricated and It is provided by transmitting it to the compressor parts that need to be cooled.

In compressors, it is generally used in the transmission of oil from the bottom of the lower casing to the bearings. centrifugal force acting on the oil as a result of the rotation of the crankshaft. are used. In current applications, the oil is first applied to the bottom of the oil suction pipe. enters through the hole. The oil advancing on the inner surface of the crankshaft, the crankshaft disc It reaches the helical channel on the surface. Oil end from the helical channel out through the channel on the crankshaft that opens into the compressor. is coming out. However, the oil in the oil suction pipe at the moment of stopping of the compressor, It is gliding towards the lower casing with the effect of gravity. Especially variable The effect of centrifugal force on low speed compressors decreases and the required amount of oil for lubrication cannot be provided. Moreover when the compressor starts, the oil is sucked from the base of the housing and transferred to the bearings. It takes some time to be delivered. During this time, sufficient oil is added to the bearings. cannot be transmitted. This situation occurs in the oil suction pipe when the compressor starts again. there is not enough oil and the oil suction pipe refills the oil in the lower casing. dry friction in the bearings and cause mechanical losses. In addition, oil absorption at low compressor speeds the moving parts of the compressor, as sufficient oil cannot be absorbed by the pipe and the necessary lubrication cannot be provided in the bearings. This compressor life and It is one of the important factors affecting productivity. Compressor at low speed Since the centrifugal force effect decreases during operation, sufficient The problem seen in transporting the amount of oil is the use of the oil suction pipe. low due to the relative speed between the crank and the lubricating screw. It ensures that a sufficient amount of oil is delivered to the bearings even at high speeds.

However, the oil suction pipe, which is advantageous for lubrication at low speeds, usage turns into a disadvantage at high revs. Excess sent to the system The amount of oil can cause the compressor to be oil-free. Also the crank high flow oil sent from the camshaft journal, at compressor noise level causes art. In order to create the relative speed in the lubrication system, the crank keeping the oil suction pipe fixed during the rotational movement of the shaft required.

In the Patent Application, the winding of a fastener holding the oil suction pipe It is explained that it is attached to the inside of the holder.

The aim of this invention is to design a compressor with improved lubrication performance. is realization.

In order to achieve the purpose of this invention, the first request and the dependent The compressor, as defined in the claims, is an oil suction device fitted to the end of the crankshaft. pipe, a slit located at the end of the oil suction pipe, extending in the horizontal plane, a joint that fits into the slit along the slit, fixed at both ends to the wrap holder contains the element.

Thanks to the connecting element, the oil suction pipe is fixed in the crankshaft. is standing. Thus, a more effective oil is produced by improving the oil reaching the bearings. suction is performed.

In one embodiment of the invention, the compressor is connected to the winding holder of the fastener. Two locking locks located opposite each other on the winding holder, ensuring its chamber, which enters the locking chamber and disconnects the fastener from the wrap holder. with two locking tabs located at both ends of the fastener It includes a locking mechanism. The locking mechanism also the locking tab extending into the opening located at the entrance of the locking chamber. includes a locking extension that prevents it from leaving the locking chamber.

Thanks to the locking mechanism, the fastening element in the horizontal and vertical axis movement is inhibited.

In the preferred embodiment of the invention, the locking tab is in the "V" forin. In this way, contacting the locking extension as the locking tab enters the locking chamber. flexing, after entering the locking chamber, the application of the locking extension As the force disappears, it returns to its original position. In this way, vertical When a force is applied to the axis, the locking tab strikes the locking extension and the locking tab is prevented from leaving the locking chamber.

In one embodiment of the invention, the compressor is placed horizontally at the bottom of the oil suction pipe. extending mutually towards each other over the slit extending along the axis, and At least two fastenings that prevent the slotted fastener from coming back contains the element. In the preferred embodiment of the invention, on the two walls of the slit There are four fixing elements from two of them located opposite each other.

In the application of the invention, the fastener is a strip-shaped rod and a flexible produced from the material.

A compressor realized to achieve the purpose of this invention is given in the attached figures. has been shown, from these figures; Figure 1 - is a section view of a compressor.

Figure 2 - Connector, oil suction pipe and winding holder exploded is the view.
