Abstract
Abstract A drive coupling is disclosed coupling a ball screw drive mechanism to a driven carriage so as to maintain precisely the position of the carriage with respect to the ball screw in directions along which the carriage moves while allowing lateral relative movement therebetween, the coupling being comprised of a bearing block receiving a pair of pins, one pin fixed to the carriage, the other fixed to the drive member of the ball screw mechanism with the pins extending transversely to each other and passing into preloaded axial bearing sets carried by the bearing block in a plane normal to the direction of the carriage movement.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
85 words
A drive coupling for connecting a first and a second member comprising: a bearing block member; a first drive member connected to said first member; a second drive member connected to said second member; said first and second drive members drivingly connected to said bearing block member by means of a sliding connection therebetween, whereby said first and second members are rigidly connected against relative movement in all directions except in the direction in which said drive members slidingly connected to said bearing block member.
Claim 2
Dependent Claim
85 words
A drive coupling for connecting a first and a second member comprising: a bearing block member; a first drive member connected to said first member; a second drive member connected to said second member; said first and second drive members drivingly connected to said bearing block member by means of a sliding connection therebetween, whereby said first and second members are rigidly connected against relative movement in all directions except in the direction in which said drive members slidingly connected to said bearing block member.
Claim 3
Dependent Claim
35 words
The drive coupling of claim 1 wherein said first and second drive members comprise pins and wherein said pins extend into preloaded axial bearings carried by said bearing block member to provide said sliding connection.
Claim 4
Dependent Claim
39 words
The drive coupling of claim 1 wherein said first and second drive members extend normally to each other and are disposed in a common plane, whereby relative rotation of said first and second members in said plaNe is prevented.
Claim 5
Dependent Claim
32 words
The drive coupling of claim 2 wherein said pins extend normally to each other and are disposed in a common plane, whereby relative rotation of said members in said plane is prevented.
Claim 6
Dependent Claim
114 words
In an arrangement wherein a rotary drive mechanism is adapted to linearly advance a carriage member by a rotary drive member coupled to said carriage and advanced by rotation of an element of said rotary drive mechanism, the improvement comprising: a bearing block member; a first drive member connected to said rotary drive member; a second drive member connected to said carriage member; said first drive member and said second member extending into said bearing block member with a sliding fit therebetween, whereby said rotary drive and carriage members are rigidly connected against relative movement in all directions except in the direction in which said rotary drive members extend into said bearing block member.
Claim 7
Dependent Claim
114 words
In an arrangement wherein a rotary drive mechanism is adapted to linearly advance a carriage member by a rotary drive member coupled to said carriage and advanced by rotation of an element of said rotary drive mechanism, the improvement comprising: a bearing block member; a first drive member connected to said rotary drive member; a second drive member connected to said carriage member; said first drive member and said second member extending into said bearing block member with a sliding fit therebetween, whereby said rotary drive and carriage members are rigidly connected against relative movement in all directions except in the direction in which said rotary drive members extend into said bearing block member.
Claim 8
Dependent Claim
29 words
The arrangement of claim 5 wherein said first and second drive members comprise pins and wherein said pins extend into preloaded axial bearings carried by said bearing block member.
Claim 9
Dependent Claim
39 words
The arrangement of claim 5 wherein said first and second drive members extend normally to each other and are disposed in a common plane, whereby relative rotation of said rotary drive and carriage members in said plane is prevented.
Claim 10
Dependent Claim
31 words
The arrangement of claim 6 wherein said pins extend normally to each other and are disposed in a common plane, whereby relative rotation of said members in said plane is prevented.
