Abstract
A forging manipulator has a traction drive with toothed wheels meshing with racks. The toothed wheels are coaxial with rail wheels supporting the manipulator and are mounted as close as possible to output shaft bearings of the drive which bearings are journalled in bearings in the chassis. Torque reaction is absorbed by members articulated to the drive transmission casing and directly or indirectly to the chassis side members.
Claims6
A forging manipulator comprising:
- a chassis;
- rail wheels rotatably mounted on said chassis for supporting the chassis so that said chassis can travel forwards and rearwards on rails, said chassis having a forward part and a rear part and forward rail wheels and rear rail wheels mounted respectively thereon;
- manipulating means mounted on the forward part of the chassis;
- laterally spaced side members on the rear part of said chassis;
- and a chassis drive unit mounted on the rear part of the chassis comprising, a transmission casing, a traction motor mounted on said casing, an output shaft extending from the transmission casing, bearing means for rotatably supporting said shaft on said casing, transmission means in said casing operably connecting said motor to said output shaft, a toothed wheel on said output shaft mounted directly adjacent said shaft bearing means for meshing with a stationary rack for moving said manipulator chassis along said rack and rails by said motor, said toothed wheel and output shaft being coaxial with respect to said rear rail wheels, transmission casing bearing means mounted on said side members in which the output shaft bearing means are journalled, and torque-absorbing means connecting said transmission casing to the rear part of the chassis.
