Five, the specific embodiment
A kind of small bore coaxial cable formula tensioner is made up of bearing (1), screw rod (2), nut (3), spring (4), thrust axis (5), back frictional disk (6), preceding frictional disk (7) etc.Screw rod (2) is fastened on the bearing (1), and bearing (1) is fastened on the storage yarn drum by screw (9); Nut (3) is screwed in that screw rod (2) is gone up and offsets with the back segment of spring (4); The front end of thrust axis (5) offsets with back frictional disk (6) rear side, and the rear end of thrust axis (5) is a guide post, and the rear side of thrust axis (5) bead part and the front end of spring (4) offset; Back frictional disk (6) offsets with the rubbing surface of preceding frictional disk (7); Preceding frictional disk (7) is fixed on the bearing (8) that links to each other with weft accumulator loam cake (12).It is characterized in that the tension adjustment parts: screw rod (2), nut (3), spring (4), thrust axis (5) all are installed in rear one side (promptly near storage yarn drum one side) of frictional disk.The external diameter of back frictional disk (6) is no more than half of storage yarn drum external diameter.The hemispherical protruded stigma (6 ') of back frictional disk (6) rear side stretches in the groove (5 ') of thrust axis (5), and the radius of hemispherical protruded stigma (6 ') can be pressed any direction swing within the specific limits less than the bottom spherical radius of groove (5 ').In addition, the rear side of back frictional disk (6) can also be designed to hemispherical groove (6 "), and is enclosed within the hemispherical protruded stigma (5 ") of thrust axis (5), and the radius of hemispherical protruded stigma (5 ") is less than the bottom radius of groove (6 ").The rubbing surface middle part of back frictional disk (6) front side then is a plane.The rear side of thrust axis (5) bead part and the front end of spring (4) offset, and the rear end of thrust axis (5) is a thin axostylus axostyle or hollow shaft (15), are matched in clearance with the hole or the axis of guide (16) of screw rod (2).Screw rod (2) is fastened on the bearing (1), and bearing (1) is fastened on the storage yarn drum by screw (9).In addition, screw rod (2) also can be designed to one with bearing (1).
In order to guarantee that it has higher ABRASION RESISTANCE and service life, frictional disk is with wear-resisting high-hardness ceramic or is coated with the light metal manufacturing of superhard material.
Operation principle of the present utility model is: be subjected to the effect of spring (4), thrust axis (5) compresses back frictional disk (6) with preceding frictional disk (7), and the yarn that passes therebetween will be subjected to certain pressure.When yarn was drawn by loom, back frictional disk (6) and preceding frictional disk (7) will be to producing a frictional force through therebetween yarn, and the position of adjusting nut (3) can change the size of frictional force.Back frictional disk not only can also move forward and backward by arbitrarily angled swing simultaneously, so the threading pin directly can be passed and yarn is taken out of in the hole of frictional disk (7) in the past, has simplified workman's operation.Owing between nut (3) and the screw rod (2) bigger coupling mechanism force is arranged, can effectively prevent to change because of reasons such as vibration cause the position of nut (3).
In addition, yarn is that the axis around frictional disk is rotating by loom and draws by frictional disk the time, so can not accumulate the flower hair between frictional disk.Pressure between two frictional disks applies by spring, when yarn movement, the pressure of yarn and two frictional disks is with different, particularly when the moment of yarn, tension force was big, yarn can separate the contact-making surface of two frictional disks, at this moment yarn will be significantly different with the pressure of two frictional disk effects, thereby make tension force that tensioner applies yarn no longer with the sexual intercourse of spring (4) applied pressure retention wire, help reducing loom and quickening the weft tension of wefting insertion during the stage, reduce the staplings rate of loom.
