Description
Technical field
The invention belongs to belt tranmission techniques field, relate to the controlled belt conveyor of a kind of frictional force.
Background technology
Traditional conveyer belt often skids between driving wheel and conveyer belt during operation, especially start and full load conditions under, beatSliding phenomenon is more serious, gently causes wearing and tearing, heavy cause conveyer belt to catch fire, and burns conveyer belt, and damage tunnel, even causes peopleMember's death by suffocation, produces and brings immeasurable loss to enterprise, so very important to transport belt slippery accident. Cause thisThe main cause of skidding is after conveyer belt work a period of time, and it is Paint Gloss that surface becomes, and the elastomeric material of conveyer belt reachesArrived certain fatigue period, it is soft that conveyer belt becomes.
For the problems referred to above, prior art in the following ways: add non-slippery substance on conveyer belt surface, adjust driving wheel with fromDistance between driving wheel or the cooling etc. of sprinkling water on conveyer belt. Driving wheel after such scheme existence is installed and the distance between driven pulleyMay pollute transmission thing from difficult adjustment, the material adding and water etc.
Though magnetorheological materials has been widely used in productive life. Because it can change by variable magnetic field rigidity and the resistance of materialBuddhist nun, is more applied to vibration damping and vibration isolation field, is not used to solve in the problem of above-mentioned frictional behaviour improvement. Therefore, asMagnetorheological materials is used for conveyer belt by fruit, and can in motion process, constantly adjust its coefficient of friction, and the problems referred to above can obtainSatisfactorily resolve.
Summary of the invention
In view of this, the object of the invention is to propose the controlled belt conveyor of a kind of frictional force, avoid existing conveyer belt tiredAfter labor, easily skid and be difficult for the problem of adjusting.
The object of the invention is to be achieved through the following technical solutions:
The belt conveyor that frictional force is controlled, comprises conveyer belt and the driving wheel to conveyer belt Contact Transmission, described transmissionOn the contact-making surface of band and/or driving wheel, be fixedly installed the skid resistant course that adopts magnetorheological rubber to make, on driving wheel, being provided with can be to instituteState skid resistant course and produce magneto motive variable magnetic field, described variable magnetic field comprises that annular is wrapped in the excitation in described drive wheel circumferencesCoil and the controllable electric power being communicated with described magnet exciting coil.
Further, the magnetic line of force of described variable magnetic field is vertically through described skid resistant course.
Further, in described driving wheel, be provided with cannelure, described magnet exciting coil is fixed in described cannelure.
