Abstract
A distribution drive for a roll in a processing machine, and particularly in a press which has an improved axial motion distribution mechanism and which requires little installation space. This is achieved by an input drive mechanism coupled to a drive having at least one pinion gear 8 which is coupled to a gear 10. Arranged on a side face of the gear 10 is a first pin 17 which, together with a second pin 22, forms a rotary joint 20 by the first pin 17 penetrating the second pin 22. Together with a bearing arm 23, the second pin 22 forms a sliding joint 21, with the second pin 22 being accommodated at the ends in the bearing arm 23, and the bearing arm 23 being coupled to the roll 3.
Claims7
A distribution drive for a roll in a processing machine, such as a printing press, comprising a roll (3) mounted for rotational and axial movement, a first drive for imparting rotational movement to said roll, a second drive for axially moving said roll, said second drive including an input drive mechanism (7) coupled to a power drive;
- said input drive mechanism including at least one pinion gear (8) operatively coupled to a mating gear (10);
- a first pin (17) positioned on a side face of said mating gear (10);
- a second pin (22) which receives said first pin (17) and forms a rotary joint (20);
- a bearing arm 23 which receives said second pin (22) and forms a sliding joint (21) with the second pin (22);
- and said bearing arm (23) being coupled to said roll (3) to form a further rotary joint (27) such that operation of said input drive mechanism by said power drive rotates said mating gear (10) to cause axial movement of said roll (3) depending upon the position of said first pin (17) on said side face of the mating gear (10).
The distribution drive of claim (1) in which said first pin is selectively positionable on the side face of said gear (10) and can be positioned coaxially with the axis of said gear (10) to eliminate axial movement of the roll (3) notwithstanding operation of the input drive mechanism (7).
The distribution drive of claim (1) in which said second pin (22) is mounted two sliding joints (21) of the bearing arm (23).
A distribution drive for a roll in a processing machine, such as a printing press, comprising a roll (3) mounted for rotational and axial movement, a first drive for imparting rotational movement to said roll, a second drive for axially moving said roll, said second drive including an input drive mechanism (7) coupled to a power drive;
- said input drive mechanism including at least one pinion gear (8) operatively coupled to a mating gear (10);
- a first pin (17) positioned on a side face of said mating gear (10);
- a hinge pin (28) which receives said first pin (17) and forms a sliding joint (21) therewith;
- a swinging arm (24) which receives said hinge pin (28) and forms a rotary joint (20) therewith for supporting the hinge pin (28) for relative rotatable movement;
- and said swing arm (24) being coupled to said roll (3) to form a further rotary joint (27) such that operation of said input drive mechanism by said power drive rotates said mating gear (10) to cause axial movement of said roll (3) depending upon the position of said first pin (17) on said side face of the mating gear (10).
