Wheel, described four groups every group two gasket rings are respectively arranged at the both sides of four guide rollers and are close to four orienting rolls
Wheel.
The guide groove to match with the upper and lower rails is provided on four guide rollers.
Guide roller installs case is further included, the guide roller installs case is hollow, above and below the guide roller installs case
Both ends are respectively arranged with two groups every group two totally four bar shaped trepannings to match with four guide roller positions, described
Guide roller installs case side is provided with to match four shaft mounting holes with four guide roller positions；Described four are led
It is located in the guide roller installs case after four shaft mounting holes of way roller.
The long side of the bar shaped trepanning is slightly larger than the diameter of the guide roller, and the broadside of the bar shaped trepanning, which is slightly larger than, leads
The thickness of way roller and equal to guide roller and four groups every group two gasket rings along guide roller and two gasket ring axis directions continuously
The combination thickness of gap.
After above-mentioned technical proposal is employed, due to further including upper guide roller group and lower guide roller group, blade is flat
Flat elongate in shape, the upper and lower both sides of blade be respectively arranged with match with upper guide roller group and lower guide roller group it is upper and lower
The axis parallel of guide rail, upper guide roller group and lower guide roller group is simultaneously vertical with the guide direction of upper and lower rails, on blade,
Lower guideway is respectively placed in guide roller group and lower guide roller group, so that blade can be in upper guide roller group and lower orienting roll
It is moved in wheel group with roll mode along the guide direction of upper and lower rails.Blade is in upper guide roller group and lower guide roller group
It is moved with roll mode along the guide direction of upper and lower rails, replaces sliding friction with the rolling friction of guide roller, substantially reduce
Resistance during blade movement, solves the collimators vanes movement speed caused by sliding friction mechanism and is difficult to significantly carry
The technical issues of high.
