Description

Rotor dip stick

Technical field

The utility model relates to the survey instrument of rotor, is exactly specifically the dip stick for measuring rotor chute degree.

Background technology

No matter production environment or household or working environment, people pay attention to noise pollution all the more.Especially commercial production occasion, it is very general that motor uses, and motor noise also needs strict management and control.Cause the factor of motor noise, for rotor part, mainly comprise grooved, slot fit and skew slot angle etc.In prior art, the shaping of rotor chute depends on mould, once mould is wrong, the actual skewed slot size caused on rotor product and design is produced larger difference, waits motor to assemble complete, finds that noise exceeds standard late in an experiment.Also there is no at present a kind of convenient, tool and method of measuring the slot slope of shaped article accurately.

Utility model content

The purpose of this utility model is to provide a kind of rotor dip stick that is convenient, measurement rotor chute degree accurately.

For achieving the above object, the technical solution adopted in the utility model is: a kind of rotor dip stick, dip stick comprises the chi body of bar tabular, the chi face, side of chi body is cambered surface, the curved surface radian of the outside surface of this cambered surface and rotor to be measured coincide, one of them chi limit, chi limit consistent with rotor flank direction on chi body arranges reference point, another chi limit is arranged size scale mark.

Compared with prior art, the utility model possesses following technique effect: adopt a chi face to be the dip stick of cambered surface, and the cambered surface of dip stick can be coincide with the curved surface radian of the outside surface of rotor to be measured, with scale and reference point on dip stick, according to the survey measurements of this dip stick, again by geometric similarity sexual intercourse, rotor chute degree can be obtained fast, to differentiate that whether product is qualified.

Embodiment

Below in conjunction with Fig. 1 to Fig. 3, the utility model is described in further detail.

A kind of rotor dip stick, dip stick comprises the chi body 10 of bar tabular, the chi face, side of chi body 10 is cambered surface, the curved surface radian of the outside surface of this cambered surface and rotor A to be measured coincide, one of them chi limit, chi limit consistent with rotor flank direction on chi body 10 arranges reference point 11, another chi limit is arranged size scale mark 12.A chi face is adopted to be the dip stick of cambered surface, and the cambered surface of dip stick can be coincide, with scale and reference point on dip stick, according to the survey measurements of this dip stick with the curved surface radian of the outside surface of rotor to be measured, again by geometric similarity sexual intercourse, rotor chute degree can be obtained fast.

Described chi body 10 is arc-shaped bar tabular chi body, and the two chi limits consistent with periphery of rotor direction are parallel to each other, and the center of described reference point 11 and size scale mark 12 has mark line to form datum line 13, and datum line 13 is perpendiculared to one another with two chi limits.Chi body 10 is designed to arc-shaped, bar tabular, be convenient to when measuring, chi body 10 and rotor A to be measured be fitted, two chi limits consistent with periphery of rotor direction on chi body 10 are parallel to each other, the datum line 13 connected between the center of reference point 11 and size scale mark 12 is perpendiculared to one another with two chi limits, do the restriction of this position relationship, when can ensure to measure with this dip stick, dip stick is positioned at accurately on the curved surface of rotor outside surface to be measured, accurately measures the reading value b in the direction of periphery of rotor shown in Fig. 3.

The skew slot angle that described dip stick is measured is determined by following relation: skew slot angle bsk=b/H × L; Wherein b is the reading value of dip stick, and H is the wide size of chi between two chi limits of dip stick, and L is the axial dimension of rotor chute part.Because the dimensions of motor grade is determined, in other words L is known, the wide size H of the chi of dip stick is also known in addition, so once read survey measurements b, then known skew slot angle bsk, for simplicity, can make the table of comparisons by the corresponding bsk of L, H and b value of correspondence, extremely be conducive to searching relevant skew slot angle bsk, without the need to each calculating.

The both sides place of described chi body 10 is made up of towards the chamfering conical surface 14,15 of interior chi face transition and annular end face 16 outer chi respectively, the scale mark of described size scale mark 12 is arranged on the chamfering conical surface 14, marking 12 corresponding readings with size scale is arranged on the outer chi face of contiguous annular end face 16, datum line 13 is arranged on outer chi face, and two ends extend on the chamfering conical surface 14,15.The scale mark of size scale mark 12 is arranged on the chamfering conical surface 14 of chi body 10, when dip stick can be made to measure, the outer end of scale mark presses close to rotor outside surface to be measured more, make the location of dip stick and reading more accurate, reduce measuring error, datum line 13 on outer chi face is extended on the chamfering conical surface 14,15, also can measure time better location survey chi, increase measuring accuracy.
