Detailed Description
The first embodiment is as follows: with reference to fig. 1 and 2, the present embodiment is an electric roller carrier, which includes a cycloidal pin gear reducer 1, a coupling 2, a hexagon head bolt 3, a hexagon nut 4, a driving shaft 5, a first key 6, a first sprocket 7, a first single-row roller chain 8, a second sprocket 9, a first driven shaft 10, a second key 11, a third sprocket 12, a second single-row roller chain 13, a second driven shaft 14, and a fourth sprocket 15;
the rotating shaft of the cycloidal pin gear speed reducer 1 is connected with a driving shaft 5 through a coupling 2, the coupling 2 is fixed through a hexagon head bolt 3 and a hexagon nut 4, a first chain wheel 7 is fixed on the driving shaft 5 through a first key 6, the first chain wheel 7 is connected with a second chain wheel 9 through a first single-row roller chain 8, the second chain wheel 9 is fixed on a first driven shaft 10 through a second key 11, a third chain wheel 12 is fixed on the first driven shaft 10, the third chain wheel 12 is connected with a fourth chain wheel 15 through a second single-row roller chain 13, the fourth chain wheel 15 is fixed on a second driven shaft 14, two rollers 16 are respectively fixed on the first driven shaft 10 and the second driven shaft 14, the distance between the centers of the two rollers 16 is 598mm, and the diameter of the roller 16 is 480 mm.
The electric roller wheel support adopts a split structure, the support is mainly used for a low-voltage rotor, the rotor can be used when the maximum diameter is 2 m & lt 3 & gt after blades are arranged on the rotor, and the height can be finely adjusted by arranging an adjusting screw between the two bodies. When the diameter of the outer circle of the rotor is very different, the lower support can be replaced, because of the chain wheel structure, a plurality of chains can be easily dismounted, because the rotating speed required by the electric roller support is very low, the cycloidal pin gear speed reducer is adopted, because the transmission ratio of the cycloidal pin gear speed reducer is very large (the transmission ratio is 87), the speed can be easily reduced to the required range.
The second embodiment is as follows: with reference to fig. 1 and 2, the present embodiment differs from the first embodiment in that: the height from the center of the electric roller bracket to the bottom surface is 1150 mm. The rest is the same as the first embodiment.
