Abstract

The invention provides a vane wheel which comprises a first disk and a second disk which are mutually parallel, a hollow cylinder for connecting the first disk with the second disk as well as a plurality of vanes radially protruding from the cylinder, wherein the vanes are clamped by the first disk and the second disk; a first penetrating hole and a second penetrating hole are respectively formed in the centers of the first disk and the second disk; and the first disk, the second disk and the cylinder are positioned on the same central axis. A main shaft connected with the vanes is arranged into a hollow structure and the first and second square penetrating holes are arranged at the central positions of the first disk and the second disk, and thus the dead weight of the vane wheel is effectively reduced and the manufacturing cost of the vane wheel is reduced.

Description

technical field [0001] The invention relates to the design and manufacture of a pneumatic wheel sander, in particular to a blade wheel used in the pneumatic wheel sander. Background technique [0002] At present, there are many types of pneumatic grinders. Their common feature is that the blades on the blade wheel are arranged on a solid main shaft. This type of vane wheel has the disadvantages of heavy weight and large volume. At the same time, since the main shaft is a solid shaft, the torque and rated power of the motor connected to the vane wheel must be increased. This will inevitably result in higher cost of supporting equipment of the blade wheel, and increase the manufacturing cost of the blade wheel. [0003] In view of this, it is necessary to improve the vane wheel in the prior art to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a blade wheel, which can effectively reduce the dead weight of...
