Disclosure of utility model

The utility model aims to overcome the defects in the prior art and provide an axial fixing device for a rotating wheel.

The purpose of the utility model is realized in the following way: the utility model provides a rotor wheel axial fixing device, includes the rotor wheel, the rotor wheel middle part transversely rotatable runs through the axis of rotation, and rotor wheel both sides are provided with two fixed plates, and both ends are fixed on the fixed plate around the axis of rotation.

Further, the front end and the rear end of the rotating shaft are respectively provided with a transverse clamping groove, and the front transverse clamping groove and the rear transverse clamping groove are symmetrically distributed.

Further, a clamping plate is arranged between the fixed plate and the rotating shaft, and the rotating shaft is fixedly connected with the fixed plate through the clamping plate.

Further, the clamping plate is clamped into the clamping groove and is fixedly connected with the fixing plate.

When the clamping plate is clamped in the clamping groove, the upper surface of the clamping plate is attached to the upper surface of the inner side of the fixed plate, the lower surface of the clamping plate is attached to the inner bottom surface of the clamping groove, namely, clearance fit is realized between the lower part of the clamping plate and the clamping groove; the limiting of the size of the clamping plate can prevent the rotating shaft from rotating or shifting when the rotating wheel rotates, and the clamping plate is directly fixed with the fixing plate through the bolts, so that the use of parts is reduced, and the cost is saved.

The beneficial effects are that: the device can be used for quickly fixing the rotating wheel shaft, the clamping plate and the clamping groove are matched in the device, so that the rotating wheel shaft can be prevented from rotating, the front and back movement of the rotating shaft is limited, and the device is more convenient than the traditional fixing mode in disassembly and has high temperature; and the fixed mode of this structure is more convenient when using, because the mode of taking the draw-in groove cardboard is fixed, consequently can shorten the length of axis of rotation for the mode of bolt-up, it is more convenient relatively when dismantling the change installation.
