Abstract
A design for a device for the reduction of movement of the main shaft (6) in the disengaged position in a transmission with at least two countershafts in which there is an axial transfer of forces between the drive shaft (7) and the main shaft (6) which is coaxially arranged through a connection of the main shaft (6) with a part of the axial bearing (13) on the drive shaft (7). There is a device (2) which is used to load the main shaft (6) against the drive shaft (7) through a loading of the part of the axial bearing (13) connected to the main shaft (6) against other parts or against the axial bearing (4) on the drive shaft (7).
Claims7
A device for reduction of movement of a main shaft (6) of a transmission having at least two counter shafts, a drive shaft (7) and a main shaft (6), the device comprising:
- in a region of the drive shaft (7) coaxially extending within the main shaft (6),
- a bearing ring (5) coaxially located on the drive shaft (7),
- a first ring (12) axially and fixedly engaged between the bearing ring (5) and the main shaft (6),
- a second ring (1) axially fixed to an end of the drive shaft (7), and
- a spring element (2) located between the first (12) and the second (1) rings and exerting
- a first axial force on the drive shaft (7) through the second ring (1) to resiliently bias the drive shaft (7) toward the main shaft (6), and
- a second axial force on the main shaft (6) through the bearing ring (5) and the first ring (12) to resiliently bias the main shaft (6) toward the drive shaft (7).
A device reducing movement, in a countershaft transmission, between a main shaft (7) and a coaxial drive shaft (6), the device comprising:
- in an end region of the drive shaft (7) extending coaxially within a hollow region of the main shaft (6),
- a bearing ring (5) having a region extending along the end region of the drive shaft (7) within the hollow region of the main shaft (6),
- a divided ring (1) axially fixed to the end region of the drive shaft (7),
- a disk spring (2) located between the bearing ring (5) and the divided ring (1), and
- a safety ring (12) axially engaged between the bearing ring (5) and the main shaft (6) in the hollow region of the main shaft (6), whereby
- the disk spring (2) exerts a first axial force on the drive shaft (7), through the divided ring (1), to resiliently bias the drive shaft (7) toward the main shaft (6), and
- the disk spring (2) exerts a second axial force on the main shaft (6), through the bearing ring (5) and the safety ring (12), to resiliently bias the main shaft (6) toward the drive shaft (7).
A device for reducing movement, in a countershaft transmission, between a main shaft (7) and a coaxial drive shaft (6), the device comprising:
- a bearing ring (5) coaxial with the drive shaft (7) and the main shaft (6),
- a first retainer element (12) axially engaged between the bearing ring (5) and the main shaft (6),
- a second retainer element (1) axially fixed to the end region of the drive shaft (7), and
- a spring element (2) located between the bearing ring (5) and the second retainer (1) so that the spring element (2) exerts:
- a first axial force on the drive shaft (7), through the second retainer (1), to resiliently bias the drive shaft (7) toward the main shaft (6), and
- a second axial force on the main shaft (6), through the bearing ring (5) and the first retainer element (12), to resiliently bias the main shaft (6) toward the drive shaft (7).
