Abstract
The utility model relates to a positioning structure of an impeller sealing ring and a mating part, which can also be applied to positioning other parts in the similar condition. The positioning structure comprises the impeller sealing ring and the mating part and is characterized in that the side end surface of the impeller sealing ring and the corresponding position on the mating part are respectively provided with a counter bore; and elastic cylindrical pins are arranged in the counter bores. The positioning structure has the advantages that the radial thickness of the sealing ring can be properly reduced, thereby not only saving the cost, but also facilitating the processing and the assembling.
Description
Technical field
The utility model relates to the position structure of impeller ring and mating parts, also can be applied to other parts of similar this situation and the location between the part.
Background technique
Seal ring is very extensive in the water pump Application for Field, and its effect also has a lot, and using with equalizing orifice as it can balancing axial thrust, also has protective price height, baroque easily damaged parts to play wear-resistant effect or the like.The localization method of former seal ring is as Fig. 1: method one is fixing by hexagon socket cap head screw (GB/T70.1-2000), in this case, though the processing of seal ring is more or less freely, hexagon socket cap head screw also is a standard piece, if but used seal ring size is less, the radial thickness of seal ring also can reduce so, and the hexagon socket cap head screw minimum gauge is M5 * 8, rarely found on the littler specification market, use this position structure, the smallest radial thickness of seal ring will be controlled at 8mm, and cost will increase like this; The method two (see figure 2) is directly to take in lower semi-circle processing one location of seal ring, processing one location groove on another mating parts, though this method is simple, if but the positioning groove processing on shoulder of the location on the seal ring or the counterpart is not just, so just be difficult to realization the accurate of seal ring and located, cost has also increased accordingly simultaneously.
Summary of the invention:
The purpose of this utility model is the existing the problems referred to above of position structure that solve impeller ring and mating parts in the prior art, and the position structure of a kind of impeller ring and mating parts is provided.The position structure of the utility model design impeller ring and mating parts, comprise impeller ring, counterpart, it is characterized in that: respectively be processed with a counterbore in the side end face of impeller ring and the relative position place on the counterpart, in counterbore, place elastic cylindrical pin.The utility model has the advantages that the suitably radial thickness of attenuate seal ring, both saved cost, also made things convenient for processing and assembling.
Description of drawings:
Fig. 1,2 is the prior art constructions schematic representation,
Fig. 3 is a structural representation of the present utility model,
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
Embodiment:
The utility model is the location of realizing seal ring by elastic cylindrical pin (straight trough heavy GB/T879.1-2000), only need be on the side end face of impeller ring and counterpart the counterbore that is complementary of processing and elastic cylindrical pin, elastic cylindrical pin is put into above counterpart is installed in impeller ring then, elastic cylindrical pin is stuck in the counterbore of the side end face of impeller ring and counterpart, the location of finishing impeller ring.Simultaneously also suitable attenuate of the radial thickness of seal ring had so both been saved cost, had also made things convenient for processing and assembled.
Claims (1)
1. the position structure of impeller ring and mating parts comprises impeller ring, counterpart, it is characterized in that: respectively be processed with a counterbore in the side end face of impeller ring and the relative position place on the counterpart, place elastic cylindrical pin in counterbore.
