Description

A COMPRESSOR COMPRISING CONNECTING ROD WITH BEARING
The present invention relates to a compressor comprising a connecting rod with bearing.
In compressors, the rotation movement driven by the engine consisting of a stationary stator and movable rotor, is transmitted by means of a crank-connecting rod-crank pin mechanism to the piston obtaining a reciprocating motion of the piston. Mechanical losses appear due to movements of the crank, connecting rod and the piston, and friction during the reciprocating motion occurring by each operation of the compressor. These mechanical losses lead to stressing of the compressor, using up of higher amounts of electricity and consequently higher consumption of energy in coolers.
Another problem with the compressors is the level of noise. Vibration levels of compressors increase due to friction of movable members in compressors, and transmitted vibrations increase the noise level of refrigerators and thus a decline in customer satisfaction.
State of the art US patent document no US2009136369 discloses a bearing placed between a crank and a body, used for decreasing friction.
State of the art Japanese patent document no JP2010255556 discloses a bearing placed between a crank and a body, used for decreasing friction.
The aim of the present invention is to realize a compressor with improved energy class and decreased noise levels.
The compressor realized to achieve the aim of the present invention is disclosed in the claims.
In the compressor realized to achieve the aim of the present invention and disclosed in claim 1 and the dependent claims, it is intended to decrease the friction between the connecting rod and the counter-weight seat. A bearing is used to decrease friction, one of the main factors influencing the operational performance of compressors. Horizontal axis motion of the connecting rod is actuated by transmitting the rotary movement of the crank by means of the crank bore of the connection rod. The motion of the connecting rod is transmitted to the piston head to pressurize the gas circulating in the compressor and gas is pressurized is the compression chamber. The connecting rod returning to its initial position with a reversal motion continues its motion by going on its next cycle. A bearing surrounding the crank bore is used to decrease friction generated during this motion between the connecting rod and the counter-weight seat. Friction decreases since the connecting rod reciprocates on the bearing without contacting the counter-weight seat by his movement on horizontal axis, thereby improving the operational performance of the compressor.
In one embodiment of the invention, the bearing is formed with its outer diameter larger than the inner diameter of the connecting rod and its inner diameter smaller than the outer diameter of the connecting rod, so that the outer and the inner diameters of the bearing do not allow intertwined engagement of the bearing and the connecting rod. The connecting rod should continuously rotate on the bearing to decrease friction during the motion of the connecting rod which transforms the rotary motion of the crank to a reciprocating motion on horizontal axis. Thanks to the bearing being produced according to indicated diameter values, the connecting rod is positioned over the bearing during the operation of the compressor, does not contact the counter-weight seat and thus friction and mechanical friction are minimized while noise level and vibration levels are decreased, thereby lifetime and operational performance of the compressor are improved.
In one embodiment of the invention, a bed for the bearing is opened on the surface of the counter-weight seat of the crank at the portion corresponding to the bottom of the connection rod, for guided placement of the bearing. Said bed enables simultaneous run of the bearing and the connecting rod, it’s also enabled that the oil collected in the bed continuously oils the bearing and protects the bearing from mechanical abrasion thereby improving the lifetime of the compressor.
In one embodiment of the invention, the depth of the bed is almost exactly equal to the lateral height of the bearing and the bearing is flush with the counter-weight seat of the crank. The bearing placed almost exactly ledgeless with the bed with respect to the counter-weight seat of the crank, run sheltered in the bed and is thus protected from mechanical abrasion during the lateral motion of the connecting rod. Micro sized particles which can damage the compressor arising as a result of said mechanical abrasion, are minimized thanks to flush placement of the bearing in the bed thereby improving the lifetime of the compressor.
In one embodiment of the invention, a spring is provided between the bearing and the bottom of the bed. Beds opened during production on counter-weight seats can be opened with varying depths in order to facilitate production and to serve a plurality of compressor types. Using bearings of different thicknesses can cause problems during production. As a result of the bearing being jammed in the lower portion of the bed, the bearing would not function properly, the connecting rod would enter the opening left from the bearing and mechanical damages could occur. Due to his placement under the bearing, the spring generate a propulsive force from the lower portion of the bearing to its upper portion, the bearing adheres to the connecting rod in lip-to-lip contact. Thus, mechanical friction is avoided, the lifetime of the compressor is improved and also a bearing of a single type is made suitable for a plurality of compressors thereby improving production costs.
In one embodiment of the invention, recesses are provided on the inner wall of the connecting rod, used for the oil ascending along the crank to pass between the inner wall of the connecting rod and the crank, to be evenly distributed around the connecting rod. The oil seeping on the bearing from the lower surface of the connecting rod which is in contact with the bearing, enables continuous and even oiling of the bearing thanks to evenly-spaced distribution on the inner wall of the recesses provided on the inner wall of the connecting rod, thereby protecting the bearing from friction and improving its lifetime. By this, the lifetime of the compressor is improved.
The compressor realized to achieve the aims of the present invention is illustrated in the accompanying drawings, wherein:

The compressor (1) of the invention comprises a cylinder block (3) having a compression chamber (2), a cylinder head (4), a valve assembly (5) arranged between the cylinder block (3) and the cylinder head (4), a piston head (6) arranged in the compression chamber (2) so as to move reciprocally, a connecting rod (7) connected to the piston head (6), a crank (8) co-axially connected to the connecting rod (7) and placed in the cylinder block (3) so as to rotate, a counter-weight seat (9) on which the connecting rod (7) rests, a body (10) on which the counter-weight seat (9) rests, a housing (11) in which the body (10) is placed, and damping means (12) damping the vibrations of the body (10). The compressor (1) of the invention comprises a bearing (13) placed between the crank bore of the connecting rod (7) and the counter-weight seat (9).
The compressor (1) rests on the crank bore of the connecting rod (7) during operation. Abrasion occurs on the connecting rod (7) and the counter-weight seat (9) due to friction between the connecting rod (7) and the counter-weight seat (9) which is in direct contact with the connecting rod (7). Abrasion and friction between the connecting rod (7) and the counter-weight seat (9) experienced during operation, are decreased thanks to the bearing (13) placed between the connecting rod (7) and the counter-weight seat (9). Thus, friction on the movable parts of the compressor (1) decrease, abrasions are avoided by decreasing friction, the energy efficiency is improved and also the lifetime of the compressor (1) is extended and customer satisfaction is obtained.
In one embodiment of the invention, the compressor (1) comprises a bearing (13), the outer diameter of which is larger than the inner diameter of crank bore of the connecting rod (7) and the inner diameter of which is smaller than the outer diameter of crank bore of the connecting rod (7). During operation of the compressor (1) the connecting rod (7) is in continuous contact with the bearing (13) thanks to the outer diameter of the bearing (13) being larger than the inner diameter of crank bore of the connecting rod (7) and the inner diameter of the bearing (13) being smaller than the outer diameter of crank bore of the connecting rod (7). Thus, the connecting rod (7) cannot contact the counter-weight seat (9), this gap formed between the connecting rod (7) and the counter-weight seat (9) minimizes energy losses resulting from friction of these parts, thereby enabling a more efficient operation of the compressor (1) and saving energy.
In one embodiment of the invention, the compressor (1) comprises a bed (14) opened on the counter-weight seat (9) of the crank. Said bed (14) in which the bearing (13) engages, acts as a guide for the bearing (13) during operation of the compressor (1). The bed (14) opened acts as a storage for the oil conveyed from the connecting rod (7) to the bearing (13), keeps the bearing (13) continuously in oil, and the bearing (13) is thus oiled throughout operation of the compressor thereby extending the lifetime of the bearing (13) and the compressor (1), and increasing customer satisfaction. Friction subjected on the bearing (13) is also minimized thanks to the oil collected in the bed (14) and thus energy is saved.
In one embodiment of the invention, the compressor (1) comprises a bearing (13) resting almost flush with the bed (14). Micro particles likely to appear in the compressor (1) due to abrasion, join oil circulation in the compressor (1) and cause damage on other parts of the compressor (1). The flush structure of the bearing (13) with the counter-weight seat (9) minimizes mechanical abrasion during operation thereby improving the lifetime of the compressor (1).
In one embodiment of the invention, the compressor (1) comprises a spring (15) placed between the bed (14) opened on the counter-weight seat (9), and the bearing (13). In production, when the bed (14) is opened deeper than the width of the bearing (13) , the bearing (13) placed in the bed (14) cannot fulfill his function properly or the connecting rod (7) can enter into the bed (14) and can thus have an adverse impact on the operational performance of the compressor (1). The spring (15) placed under the bearing (13) and on the bed (14) opened on the counter-weight seat (9) generates stress between the bearing (13) and the bed (14) and enables flush operation of the bearing (13) with the bed (14). Thus, defects resulting from production errors are avoided while the connecting rod (7) is kept in continuous contact with the bearing (13) and friction is decreased thereby providing positive impact on the operational performance of the compressor (1).
In one embodiment of the invention, the compressor (1) comprises a connecting rod (7) having channels in grooved structure on its inner surface. The movable parts of the compressor (1) require regular oiling during operation. Abrasion can be experienced on parts which do not contact sufficient amounts of lubricating oil, and also micro-sized metal particles resulting from abrasion can lead to malfunction in the compressor (1). The oil conveyed along the crank (8) during operation reaches the connecting rod (7) and is evenly delivered to the surrounding area from the bottom surface of the connecting rod (7) thanks to the grooved structure. Thus, the bearing (13) is continuously fed with the oil conveyed by the connecting rod (7), abrasion of the bearing (13) is avoided, and the lifetime of the compressor (1) is extended therefore customer satisfaction is improved.
The utility of the invention is avoiding friction generated during operation of the compressor and improving the operational performance of the compressor (1) positively by means of a bearing (13) between the connecting rod (7) and the counter-weight seat (9) in compressors (1).
