Abstract
A tension transmission device as a control system for a probing portion of a three-dimensional mechanical probe is fitted to a support portion. The tension transmission device includes a driving shaft, a first tension member, and a second tension member. The driving shaft defines first and second fastening points. The first fastening point and the second fastening point are located at axially-distanced points of the driving shaft which are not diametrically opposite. The first and second tension members wind around a circumference of the driving shaft guided by a first pulley and a second pulley, to rotate and manipulate the driven shaft of the probing portion.
Claims17
A three-dimensional mechanical probe comprising:
- a support portion comprising a tension transmission device comprising a driving shaft, a first tension member, and a second tension member, wherein the driving shaft defines a first fastening point and a second fastening point, the first fastening point and the second fastening point are located at different diametric planes of the driving shaft, the first tension member is connected to the first fastening point and winds around a circumference of the driving shaft, and the second tension member is connected to the second fastening point and winds around the circumference of the driving shaft;
- and
- a probing portion comprising a driven shaft, wherein the first tension member and the second tension member are connected to the driven shaft.
A tension transmission device comprising:
- a driving shaft defining a first fastening point and a second fastening point, wherein the first fastening point and the second fastening point are correspondingly located on different diametric planes of the driving shaft;
- a first tension member connecting to the first fastening point and winding on the driving shaft circumferentially;
- and a second tension member connecting to the second fastening point and winding on the driving shaft circumferentially.
