A bale wrapping device for a round baler includes a drive roll which can be brought into engagement with a wrapping material roll, and a drive and brake device connected to the drive roll. The drive and brake device is connected both to a variably tensionable drive belt and to a variably tensionable brake belt.

A lock device body includes a brake member fastening a rod to lock the rod, a piston that press-opens a pair of pressure-bearing sections of the brake member by using an expansion member to unlock the rod, and an operation element for manually operating the piston, the operation element includes a shaft threaded in a screw hole, a pressure plate formed on one end of the shaft and located in the pressure chamber, and a sealing member disposed on the pressure plate. When the shaft is threaded into a lock release position, an operation end becomes an unextending state while the pressure plate displaces the piston to the lock release position, and, when the shaft is threaded back to a lock position, the operation end extends from the screw hole to the outside while the sealing member seals the screw hole to isolate the screw hole from the pressure chamber.

The concept described herein relates to a pedal having a pedal body, a pedal axis which extends at least partly through the pedal body, wherein the pedal body is supported to be rotatable on the pedal axis, and an adjustable rotation brake which, during rotation of the pedal body, exerts an adjustable braking force on the pedal axis in order to brake the rotation of the pedal body when compared to an unbraked rotation.

An assembly is described for braking and indexing rotating components, including guide rollers of balers. A wheel is attached to a rotating component and is surrounded, at least in part, by a traction device. A tensioning assembly with a lost motion linkage is attached to the traction device and to a frame. A counterforce assembly is also attached to the traction device and to the frame. When a portion of the tensioning assembly is moved in a braking direction, the stop prevents further movement of the lost motion linkage to apply a tensioning force to the traction device. The tensioning force is resisted by the counterforce assembly to impose a braking force on the wheel and thereby brake the rotating component. Moving the portion of the tensioning assembly in a release direction moves the lost motion linkage away from the stop, thereby reducing the braking force on the wheel.

A braking system may include a brake assembly having a brake shaft and a brake lever coupled to the brake shaft. The system may also include a brake cylinder having a first chamber, a second chamber, a piston positioned between the chambers and a piston rod extending outwardly from the piston. The piston rod may be configured to be coupled to the brake shaft such that movement of the piston rod results in rotation of the brake shaft. In addition, the system may include a first valve configured to control a supply of working fluid to the first chamber and a second valve configured to control a supply of the working fluid to the second chamber. By adjusting a position of the first valve and/or the second valve, a braking force applied between the brake assembly and a drum of the draw works may be controlled.

A torque limiting assembly for use with an actuator having a torque transfer output, the assembly comprising a brake pad, a band connected at a first extremity to a first extremity of the brake pad and a cam linking a second extremity of the band to a second extremity of the brake pad. The brake pad and the band are configured to wrap around the a torque transfer output and the positioning of the cam in a first position frictionally engages the brake pad and the band with the a torque transfer output while the positioning of the cam in a second position disengages the brake pad and the band with the a torque transfer output.
