Definitions
- the depression 84 includes an elongated groove 88.
- the key 80 will mate with the groove 88 and prevent rotation of the carriage 20 relative to the nut 76, about a longitudinal axis 50 of the lead screw 24.
- the rounded top surface 82 of the nut 76 allows the carriage 20 to "float" on the nut 76, or move freely in virtually all directions while still maintaining contact with the nut 76.
- the washer 78 is bonded to the underside 86 of the carriage 20 to prevent the nut 76 from becoming dislodged from the depression 84.
