Abstract
A pin for connecting a gear to a supporting member has a first and a second longitudinal end portion connectable to the supporting member; a first intermediate portion extending from the first end portion; and a second intermediate portion extending from the second end portion, and which differs in size from the first intermediate portion and has a flexural strength differing from that of the first intermediate portion.
Claims6
A pin (14) for connecting a gear (5) to a supporting member (6);
- the pin (14) having a respective axis (15), and comprising:
- a first (19) and a second (20) longitudinal end portion connectable to said supporting member (6);
- a first intermediate portion (21) extending from said first end portion (19);
- and
- a second intermediate portion (22) extending from said second end portion (20);
- characterized in that said first (21) and said second (22) intermediate portion differ from each other in size and in flexural strength, wherein said first intermediate portion (21) has a cross section, measured in a plane perpendicular to said axis (15), greater than a cross section of said second intermediate portion (22) measured in a further plane parallel to said plane;
- and
- wherein the pin is defined laterally by a cylindrical supporting surface (18), and by also comprising a single tubular portion (24) projecting, coaxially with said axis (15), from said first intermediate portion (21), and surrounding said second intermediate portion (22);
- said single tubular portion (24) being defined externally by said cylindrical surface (18).

A mechanical transmission (1) comprising:
- a gear (5);
- a supporting member (6), wherein the supporting member (6) comprises:
- a first (8) and a second (9) substantially platelike portion facing and connected to each other with the gear (5) interposed between said first (8) and said second (9) portion;
- and
- a pin (14) connecting the gear (5) to the supporting member (6), the pin (14) having
- a respective axis (15), the pin (14) comprising:
- a first longitudinal end portion (19) connected to said second platelike portion (9);
- and
- a second longitudinal end portion (20) connected to said supporting member (6);
- a first intermediate portion (21) extending from said first end portion (19);
- and
- a second intermediate portion (22) extending from said second end portion (20), wherein the first intermediate portion (21) and the second intermediate portion (22) are cylindrical;
- characterized in that said first (21) and said second (22) intermediate portion differ from each other in size and in flexural strength, wherein said first intermediate portion (21) has a cross section, measured in a plane perpendicular to said axis (15), greater than a cross section of said second intermediate portion (22) measured in a further plane parallel to said plane;
- and
- wherein the pin is defined laterally by a cylindrical supporting surface (18), and by also comprising a single tubular portion (24) projecting, coaxially with said axis (15), from said first intermediate portion (21), and surrounding said second intermediate portion (22);
- said single tubular portion (24) being defined externally by said cylindrical surface (18).
