Definitions

  • This invention relates to a pump impeller design and in particular, relates to a method of making a pump impeller.
  • This invention provides a method for affixing a disc having impeller blades formed about its periphery onto a hub in a fast and economical manner.
  • a straight coarse knurl is cut into the reduced diameter portion of the hub, and a chamfer is cut around both ends of the circular center bore of the impeller disc.
  • the knurled section of the hubs reduced diameter portion is pressed into the center bore of the impeller disc and the outer annular edge of the reduced hub portion is swaged into the adjacent chamfer to hold the disc solidly against the shoulder on the hub.
  • FIG. 1 illustrates a disc having turbine blades formed about its periphery and an impeller hub in an unassembled relation
  • FIG. 2 illustrates the step of pressing the knurled section of the hub into the center opening of the disc
  • FIG. 3 is a sectional view taken along the line 33 of FIG. 2 and looking in the direction of the arrows;
  • FIG. 4 illustrates the step of swaging the end of the hub to lock the disc in place
  • FIG. 5 is an end view taken from the left end of FIG. 4.
  • FIG. 1 there is illustrated a disc having a plurality of turbine pockets 12 formed about its peripheral edge, and a hub 14 having a reduced diameter 3,734,697 Patented May 22, 1973 portion 16.
  • the disc 10 has a center opening 18 provided with a chamfer 20 formed in both surfaces of disc 10.
  • the hub 14 is made as an automatic screw machine product.
  • a plurality of longitudinal grooves 22 are cut into the reduced diameter portion 16 adjacent the shoulder 24 to provide a straight coarse knurl section 26.
  • the outer annular end 28 of reduced diameter portion 16 is machined to the depth of grooves 22.
  • the knurled section 26 is pressed into the center opening 18 to cut corresponding grooves 30 in the disc internal diameter, as depicted in FIG. 5, until the inward side of disc 10 abuts against shoulder 24.
  • the result of this pressing step is to provide a good driving bond between the impeller disc 10 and the hub 12, which is as effective as a key or spline without causing an excessive interference fit that would distort the disc 10.
  • the assembly depicted in FIG. 2 is then placed in a press to swage (FIG. 4) the outer annular edge 28 of hub reduced portion 16 into the chamfer 20 for the purpose of holding the disc 10 rigidly against the shoulder 24 on the hub 14.
  • the die for this swaging operation is a specially designed concentric ring to control the concentricity of the swaged portions 34 with the hub 14.
  • the die I.D. is controlled so that all the metal displaced goes against the impeller disc 10 and not into the bore of the hub, as would be the case if the end 28 of hub 14 were swaged with a fiat die over its entire end area.
  • FIG. 5 depicts the finished composite impeller mounted on a shaft 40 and fixed thereto by a spline or key 42.
