Detailed description of the invention
Fig. 1 is the schematic diagram of the turbine flowmeter impeller of the utility model embodiment.
Fig. 2 is the schematic diagram of the support component of the utility model embodiment.
Fig. 3 is the schematic diagram of the baffle of the utility model embodiment.
Specific embodiment
In the following, being further described in conjunction with substantive distinguishing features and advantage of the example to the utility model, but this is practical new
Type is not limited to listed embodiment.
As shown in figures 1 and 3, the turbine flowmeter impeller of the present embodiment includes impeller bodies 1, shaft 2 and support component
3, impeller bodies 1 are arranged in shaft 2, and support component 3 is arranged in both ends of the shaft.The support component 3 includes first bearing 31,
Second bearing 32, sleeve 33 and elastic ring 34,33 both ends of sleeve are respectively equipped with the first groove 331 and the second groove 332, the
Connecting hole 333 is equipped between one groove and the second groove, shaft 2 is arranged in connecting hole 333.The first bearing 31 setting is the
In one groove 331, second bearing 32 is arranged in the second groove 332, and elastic ring 34 has sidewall 34 1 and annular protrusion 342, ring
342 projection of shape protrusion is in 1 one end of sidewall 34.Elastic ring 34 is arranged in the second groove 332, and side wall is located at second bearing 32 and the
Between the inner wall of two grooves 332, annular protrusion 342 is located at 32 one end of second bearing.In above-mentioned technical proposal, pass through setting elasticity
Circle 34 can make for Elastic Contact between second bearing and sleeve, and when being shaken shaft generation deflection, elastic ring can be inhaled
Vibration is received, shaft and bearing decentraction are avoided, reduces shaft abrasion.By the way that annular protrusion 342 is arranged, second bearing can be limited
Position, avoids its axial displacement.By setting first bearing 31 and second bearing 32, can reduce between sleeve 33 and shaft 2
