Abstract
The invention discloses a variable-torque driven shaft, which comprises a central shaft body, supporting bearings, an electromagnetic coil, a fixed base and a torque controller, wherein the central shaft body penetrates through the central position of the electromagnetic coil; the inner diameter of each supporting bearing is the same with the diameter of the outer circle of the central shaft body; the number of the supporting bearings is two; the two support bearings are separately arranged at the two lateral sides of the electromagnetic coil; the outer circle of the electromagnetic coil is connected with the fixed base; the torque controller and the electromagnetic coil are in linear connection. By adopting the manner, during rotating, the variable-torque driven shaft utilizes the constant resistance given by the electromagnetic coil to the central shaft body, the torque is adjustable and the rotating speed is smoother under the driving of a rolling machine, so that the rolled matters have certain tension and stability.
Description
Technical field
The present invention relates to the driven shaft design field of plait mill, particularly relate to a kind of change moment of torsion driven shaft.
Background technique
At trade mark, print, weave cotton cloth, the industry such as adhesive tape, all need to use plait mill, carry out the rolling of product or unreeling of raw material.In the process of coiled strip, for the situation such as do not make rolled up material generation fold, get loose or break, often require plait mill in operation process, to possess certain speed and tension force, thereby improve the quality of coiled strip.
The charge bar of plait mill is generally active rotation, in use needs the cooperation of driven shaft.Common driven shaft does not have moment of torsion stabilizer, due to pulling of inertia and plait mill, easily causes rolled up material occur loose and break, the normal progress that impact is produced.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of change moment of torsion driven shaft, and rotational resistance is adjustable, and smooth running is easy to adjust.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of change moment of torsion driven shaft is provided, comprise: center axis body, spring bearing, electromagnetic coil, fixed pedestal and torque controller, described center axis body is through the central position of electromagnetic coil, the internal diameter size of described spring bearing is identical with the excircle dimension of center axis body, spring bearing quantity is 2, lay respectively at the both sides of electromagnetic coil, the cylindrical of described electromagnetic coil is connected with fixed pedestal, adopts linear connection between described torque controller and electromagnetic coil.
In a preferred embodiment of the present invention, keyway and threaded bolt are contained in one end of described center axis body.
In a preferred embodiment of the present invention, described torque controller comprises power switch, direction controller and power regulator.
The invention has the beneficial effects as follows: a kind of change moment of torsion driven shaft that the present invention points out, in rotary course, use electromagnetic coil to constant resistance of center axis body, moment of torsion is adjustable, under the drive of plait mill, make rotating speed more steady, thereby keep being there is certain tension force and stability by Roll Sushi.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is a kind of structural representation that becomes one preferred embodiment of moment of torsion driven shaft of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, center axis body, 2, spring bearing, 3, electromagnetic coil, 4, fixed pedestal, 5, torque controller.
Embodiment
Below the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of change moment of torsion driven shaft, comprise: center axis body 1, spring bearing 2, electromagnetic coil 3, fixed pedestal 4 and torque controller 5, described center axis body 1 is through the central position of electromagnetic coil 3, the internal diameter size of described spring bearing 2 is identical with the excircle dimension of center axis body, closely cooperate, spring bearing 2 quantity are 2, lay respectively at the both sides of electromagnetic coil 3, coordinate outer carrier to use, install firmly, good stability, the cylindrical of described electromagnetic coil 3 is connected with fixed pedestal 4, adopts linear connection between described torque controller 5 and electromagnetic coil 3.
The present invention becomes moment of torsion driven shaft not only can be applied in plait mill cooperation field; can also be applied in some starting protections or mechanical transmission fields; keyway and threaded bolt are contained in one end of described center axis body 1; can coordinate various transmission paries to use; easy for installation; dismounting is quick, can bear compared with high pulling torque, and rotational stabilization is good.
Further, described torque controller 5 comprises power switch, direction controller and power regulator.Power switch is connected with direction controller, controls electric current outbound course, and direction controller is connected with power regulator, controls the power that electromagnetic coil 3 obtains, thereby center axis body 1 is stablized but adjustable moment of torsion.
In sum, a kind of change moment of torsion driven shaft that the present invention points out, compare with general driven shaft, there is preset moment of torsion, coordinate plait mill to use, avoid startup suddenly in operation process or velocity variations and the product that causes comes off or ruptures, can give production line certain tension force, good stability, easy to adjust, be widely used.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
