(action of actuator)
Below, the action of the actuator of present embodiment is described.
At first, the pressurized air that utilizes illustrated air-source never to offer each Hydrostatic Cushion SP makes bearing 5 maintain the slightly state of isolation with respect to guide rail 4.
At this, when motor 10 drives driving pulley 1, bearing 5 via endless belt 3 along guide rail 4 almost without frictionally moving.And, by the driving of control driving pulley 1, can make bearing 5 straight line motion reciprocally between the two ends of guide rail 4.
And, in the present embodiment, carry via bearing part 5A, 5D carrying object O the second connecting member 8 and with bearing part 5B, 5C that endless belt 3 links be split, but parts in the past are one, the endless belt is connected in the bearing that carries carrying object O comes transmission of drive force.Therefore, in parts in the past, be delivered to carrying object from the vibration of endless belt, might produce harmful effect to carrying object.But, in the present embodiment, carry via bearing part 5A, 5D carrying object O the second connecting member 8 and with bearing part 5B, 5C that endless belt 3 links be split, utilization is cushioned the vibration from endless belt 3 the 3rd connecting member 9 that they link up, and therefore the vibration from endless belt 3 is difficult for being delivered to carrying object.
Particularly, vibration from endless belt 3 is delivered to bearing part 5B, 5C, but because the 3rd connecting member 9 is flat parts, has the character that in the axial direction resiliently deformable does not occur and can resiliently deformable on the direction beyond axially, therefore, resiliently deformable can not occur owing to transmitting the vibration that comes in the 3rd connecting member 9 in the axial direction, but to axial direction (radially) deflection (resiliently deformable) in addition.Strictly speaking, the 3rd connecting member 9 is slightly flexible in the axial direction, then is the amount of deformation of negligible degree but compare with deflection radially, therefore can say in fact in the axial direction can not deform.
Therefore, although from the axial vibration in the vibration of endless belt 3 via the 3rd connecting member 9 a little bearing part 5A, 5D of being delivered to, but the vibration of the direction axially is delivered to bearing part 5A, 5D hardly owing to the distortion of the 3rd connecting member 9 is cushioned.Consequently, even in the situation that bearing 5 with high-speed mobile and acceleration or deceleration sharp, little vibration of the bearing 5 in mobile also can be suppressed and be obtained high linarity.Therefore in addition, little vibration is difficult for being delivered to the carrying object O that is equipped on bearing 5, hardly can be owing to from the vibration of endless belt 3 carrying object O being produced harmful effect.And the 3rd connecting member 9 is flat parts, therefore, so long as to axial direction in addition, in the situation that all identical to the characteristic of which direction deflection buffering vibration, can not make owing to the direction of deflection the easy resiliency of vibration different.
And the section of guide rail 4 is roughly U word shape, so the outer surface of sidewall 4b, 4b and diapire 4a is made of the plane, has advantages of that therefore to be easy to improve machining accuracy (particularly linear precision) such.
Such actuator can be fit to be used in manufacturing installation, testing fixture and conveying device etc., though be particularly suitable for straight line pilot bearing device bearing with high-speed mobile and sharp under the condition of acceleration or deceleration running also require bearing to carry out the various devices of high-precision traveling priority.
Above mode of execution of the present utility model is illustrated, but the utility model is not limited to this, can carry out various changes, improvement.For example, in the present embodiment, bearing 5 links up four bearing part 5A, 5B, 5C, 5D and consist of, but the number of bearing part is so long as get final product especially restriction more than three.
In addition, among four bearing part 5A, 5B, 5C, the 5D two are that band connects and uses bearing part, two is the carrying object bearing part, but as long as band connect with bearing part be more than one, the carrying object bearing part is to clip in the axial direction the plural bearing part that the band connection configures with the mode of bearing part, their number is especially restriction.And, in four bearing part 5A, 5B, 5C, 5D, bearing part 5B, 5C with axial central authorities use bearing part as being with to connect, use bearing part but also can connect as band with bearing part 5A, 5D beyond the axial central authorities, and with bearing part 5B, the 5C of axial central authorities as the carrying object bearing part.That is, connect with bearing part and carrying object bearing part as long as the bearing part function more than three is separated into band, the axial position of each bearing part does not limit especially.
