The technical scheme that the utility model conveyor transmission drum adopts is as follows:
The utility model conveyor transmission drum, comprises cylinder skin, former, wheel hub and main shaft, and cylinder intracutaneous portion time interval is provided with two formers, is provided with a wheel hub in the middle part of each former, and main shaft is fixedly connected with wheel hub through wheel hub, reinforcement assembly is provided with between cylinder skin and former, described reinforcement assembly comprises fastening ring, the outer wall of fastening ring is affixed on the inwall of cylinder skin, the circular groove snapped in for former is provided with in the inside of fastening ring, the edge of former snaps onto in circular groove, a collar is provided with in the left and right sides of fastening ring outside, cylinder intracutaneous wall is provided with the draw-in groove matched with collar, collar snaps onto in draw-in groove, a coupling link is respectively arranged with in the left and right sides of former, coupling link outer wall to be close on fastening ring inwall and to be fixedly connected with fastening ring, the cross section of described coupling link inner ring is trapezoidal shape.
As preferred version of the present utility model, described cylinder suitcase draws together endothelium, crust and seal ring, crust is placed on endothelium outside and is tightly connected by seal ring and endothelium, outside crust, middle part is provided with rubber layer, left and right portion outside crust is provided with skid resistant course, and skid resistant course is provided with anti-slip veins.
As preferred version of the present utility model, the barrel of crust is provided with several aspirating holes, aspirating hole is between rubber layer and skid resistant course, and the interlayer that endothelium and crust are formed forms cavity of bleeding, and seal ring side is provided with extraction pipe.
The advantage of the utility model conveyor transmission drum is, and friction force between load-transfer device is good, prevents cylinder from occurring skidding, simultaneously the good integrity of cylinder, and have and well do torsion effect, when preventing cylinder load excessive, the situation of distortion appears in cylinder former.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model conveyor transmission drum.
Fig. 2 is the A-A cutaway view of Fig. 1 of the utility model conveyor transmission drum.
Detailed description of the invention
As shown in drawings, the utility model conveyor transmission drum, comprise cylinder skin 1, former 2, wheel hub 3 and main shaft 4, the inner time interval of cylinder skin 1 is provided with two formers 2, a wheel hub 3 is provided with in the middle part of each former 2, main shaft 4 is fixedly connected with wheel hub through wheel hub 3, between cylinder skin 1 and former 2, be provided with reinforcement assembly.
Drive wheel hub 3, former 2 and cylinder skin 1 synchronous axial system when main shaft 4 rotates, thus drive the tape transport operation being wrapped in cylindrical outer.By arranging reinforcement assembly between cylinder skin and former, when cylinder load can be prevented excessive there is the situation of torsional deflection in former, extends the service life of cylinder.
Reinforcement assembly comprises fastening ring (5), the outer wall of fastening ring (5) is affixed on the inwall of cylinder skin (1), the circular groove snapped in for former is provided with in the inside of fastening ring (5), the edge of former (2) snaps onto in circular groove, the left and right sides outside at fastening ring (5) is provided with a collar (6), cylinder skin (1) inwall is provided with the draw-in groove matched with collar, collar (6) snaps onto in draw-in groove, a coupling link (7) is respectively arranged with in the left and right sides of former (2), coupling link (7) outer wall to be close on fastening ring (5) inwall and to be fixedly connected with fastening ring, the cross section of described coupling link (7) inner ring is trapezoidal shape.
Inside due to fastening ring is provided with the circular groove snapped in for former; the edge of former snaps onto in circular groove; and the collar of fastening ring both sides external snaps onto in draw-in groove; thus former, fastening ring and cylinder skin are fixed together; playing the effect of support by arranging coupling link 7, can the former 2 be positioned in the middle of two coupling links 7 be protected.
Described cylinder skin 1 comprises endothelium 1-1, crust 1-2 and seal ring 1-3, crust 1-2 is placed on endothelium 1-1 outside and is tightly connected by seal ring 1-3 and endothelium, the outer middle side part of crust 1-2 is provided with rubber layer 1-4, left and right portion outside crust 1-2 is provided with skid resistant course 1-5, and skid resistant course 1-5 is provided with anti-slip veins 1-6.
Rubber layer 1-4 can increase the contact of load-transfer device and cylinder skin, and cylinder skin is contacted closely with load-transfer device, thus improves friction force.Anti-slip veins can increase load-transfer device and cylinder skin friction force further, prevents skidding.
The barrel of crust 1-2 is provided with several aspirating hole 1-7, and aspirating hole is between rubber layer 1-4 and skid resistant course 1-5, and the interlayer that endothelium 1-1 and crust 1-2 is formed forms cavity of bleeding, and seal ring 1-3 side is provided with extraction pipe 8.Extraction pipe is connected with air pump, because load-transfer device is close to cylinder skin outside, when air pump starts, can be taken away by the gas between rubber layer and skid resistant course by aspirating hole 1-7, form suction, improve the adsorption affinity between load-transfer device and cylinder skin.
