As an optimized technical scheme of the utility model, the shield passes through the screw installation on the axle bed.
As an optimized technical scheme of the utility model, the rotation axis welding spare passes through the bearing to be fixed in the inside of axle bed.
As an optimized technical scheme of the utility model, axle bed and rotation axis welding spare seal through the dust ring and link to each other.
As an optimized technical scheme of the utility model, the shield passes through the fix with screw on the axle bed.
As an optimal technical scheme of the utility model, slotted nut passes through the screw thread with the rotation axis welding spare and links to each other.
The utility model has the advantages that: the free wheel has the advantages of simple structure and process design, large bearing capacity, no maintenance, low manufacturing and maintenance cost, high reliability and the like.
Description of the drawings:
fig. 1 is a cross-sectional view of the present invention;
fig. 2 is a schematic view of the three-dimensional structure of the present invention.
In the figure: 1. bearing, 2, rotation axis welding piece, 3, axle bed, 4, packing ring, 5, slotted nut, 6, shield, 7, split pin, 8, screw, 9, dust ring.
The specific implementation mode is as follows:
the following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined.
Example 1
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a free wheel device for aerial working platform, including bearing 1, rotation axis welding piece 2, axle bed 3, packing ring 4, slotted nut 5, shield 6, split pin 7, screw 8 and dust ring 9, the mid-mounting of axle bed 3 has rotation axis welding piece 2, bearing 1 is all installed at the both ends of rotation axis welding piece 2, dust ring 9 is installed with the junction of rotation axis welding piece 2 to axle bed 3, slotted nut 5 is installed to the one end of rotation axis welding piece 2, be equipped with split pin 7 on the slotted nut 5, packing ring 4 is installed with the junction of rotation axis welding piece 2 to slotted nut 5, shield 6 is installed to the one end of axle bed 3.
The dust cover 6 is arranged on the shaft seat 3 through a screw 8.
The rotating shaft weldment 2 is fixed inside the shaft seat 3 by a bearing 1.
The shaft seat 3 is connected with the rotating shaft welding piece 2 in a sealing way through a dustproof ring 9.
The dust cover 6 is fixed on the shaft seat 3 through a screw 8.
The slotted nut 5 is connected to the rotary shaft weldment 2 by threads.
The working principle is as follows: a free wheel device for an aerial work platform comprises a bearing 1, a rotating shaft welding piece 2, a shaft seat 3, a gasket 4, a slotted nut 5, a dust cover 6, a split pin 7, a screw 8 and a dust ring 9; mainly by rotation axis welding piece 2, bearing 1 and axle bed 3 are constituteed, wherein rotation axis welding piece 2 comprises axle and flange board welding, the flange board is used for installing the tire, bearing 1 impresses axle bed 3, the axle is pressed into bearing 1 again, relies on slotted nut 5 and split pin fastening axle again to prevent that axle and bearing from droing, axle bed 3 is fixed on the frame, the rotation axis welding piece 2 of connecting the tire like this will be driven under the rotation of electricity driving wheel and freely rotate. The above summary realizes the free rotation working principle of the free wheel; the rotating shaft welding part 2 is formed by welding a shaft and a flange plate, wherein the flange plate is used for mounting a tire; pressing the bearing 1 into the shaft seat 3, and then assembling the bearing welding assembly 2 and the bearing in a matching way; then the slotted nut 5 is screwed into the shaft end thread and tightened by a torque wrench, and meanwhile, a cotter pin 7 is threaded to prevent the slotted nut from loosening under extreme conditions.
