When a gear pump is in operation, there is a driving gear and a driven gear. A. Not subjected to radial force B. Subjected to equal radial forces C. The former is subjected to a greater radial force D. The opposite of C. Hint: The angle between the radial hydraulic pressure acting on the driving tooth and the meshing force is greater than 90°, so their resultant force is small ； The angle between the radial hydraulic pressure acting on the driven tooth and the meshing force is less than 90°, hence their resultant force is large.
C. The former is subjected to a greater radial force
