Abstract
A two-piece connecting rod for a reciprocating hermetic compressor, of the type comprising a first connecting rod portion (20), including a smaller eye (21) and the rod (22) of the connecting rod, and a second connecting rod portion (30), including a larger eye (31), and further comprising: an engaging element (23), provided at one of the parts defined by the first and second connecting rod portions (20, 30); a receiving housing (32), provided at the other of said parts and shaped in such a way as to receive during the assembly of the connecting rod the engaging element (23), and permit the articulation between the first and second connecting rod portions (20, 30), at a diametral plane common to both the eyes and the geometrical axis of the rod (22) of the connecting rod, and mounting means (40), carried by one of said first and second connecting rod portions (20, 30) and acting on the other of said portions, in order to prevent said portions from moving away from each other, by involuntary mutual axial spacing at said common diametral plane.
Claims
1. A two-piece connecting rod for a reciprocating hermetic compressor, of the type comprising a first connecting rod portion (20) , including a smaller eye (21) and at least part of the rod (22) of the connecting rod, and a second connecting rod portion (30) , including a larger eye (31) , respectively mounted to a piston (10) and to an eccentric pin (11) of the compressor, characterized in that it comprises: an engaging element (23) , provided at one of the parts defined by the first and second connecting rod portions (20, 30) ; a receiving housing (32) , provided at the other of said parts and shaped in such a way as to receive during the assembly of the connecting rod the engaging element (23) , in order to permit an articulation between the first and second connecting rod portions (20, 30), at a diametral plane common to both the eyes and the geometrical axis of the rod (22) of the connecting rod, said receiving housing (32) including at least a pair of opposite lateral walls defined by lower and upper radial projections (35, 36) , and axially spaced one from the other by a distance slightly larger than the diameter of the engaging element (23) , and disposed so as to avoid relative movements between said first and second connecting rod portions (20, 30) at a plane orthogonal to said common diametral plane,- and mounting means (40) , having engaging portions (41, 42) and being carried by one of said first and second connecting rod portions (20, 30) , and acting on the other of said portions, in order to prevent said portions from moving away from each other, by involuntary mutual axial spacing at said common diametral plane.
2. A two-piece connecting rod, as in claim 1, characterized in that the engaging element (23) includes lateral portions, orthogonally projecting from the common diametral plane.
3. A two-piece connecting rod, as in claim 2, characterized in that the engaging element (23) is in the form of a cylindrical body, projecting from a free end (22b) of the rod (22) of the connecting rod and occupying at least part of the thickness (E) of said rod (22) .
4. A two-piece connecting rod, as in claim 3, characterized in that the mounting means (40) is defined by a flexible clamp with a "U" profile, surrounding the lateral portions of the engaging element (23) , orthogonally projecting from the common diametral plane and with its end portions (41, 42) acting against respective stop projections (37) provided on the lateral wall of the larger eye (31) .
5. A two-piece connecting rod, as in claim 4, characterized in that the engaging element (23) has a lateral guide element (24) that guides said engaging element (23) during the mounting thereof to the receiving housing (32) , through lateral walls of a through axial slot provided on one of the lateral walls of the receiving housing (32) .
6. A two-piece connecting rod, as in claim 5, characterized in that the lateral guide element (24) is defined by a lateral wall portion (24) of the rod (22) of the connecting rod with a thickness equal to the difference between the thickness (E) of said rod (22) and the diameter of the engaging element (23) .
7. A two-piece connecting rod, as in claim 6, characterized in that the lower and upper radial projections (35, 36), of the the receiving housing (32) projecting from the lateral surface of the larger eye (31) , the axial slot on the lateral wall of the receiving housing (32) being defined by the spacing between the lower radial projections (35) , each radial projection (35, 36) having a respective arcuated internal wall, defining a circular tranversal profile for the receiving housing (32) .
8. A two-piece connecting rod, as in claim 7, characterized in that the radial projections (35, 36) are provided, on each respective external wall, of a respective stop projection (37) , in order to receive and retain the corresponding end portion of the flexible clamp (40) .
