Abstract
The invention relates to a method for installing a rotational speed probe of a rotary machine, which comprises the following steps of: selecting a number of rotation turns while installing the rotational speed probe by determining a gap between adjacent screw threads of the rotational speed probe to be installed; seeking and determining that a rotational speed probe hole is just in alignment with the top of a tooth top of a gear and that the top of the tooth top vertically corresponds to the central position of the rotational speed probe hole on a housing case; manually installing the rotational speed probe into the found rotational speed probe hole in a rotating way and correspondingly marking the position of any point of the housing case corresponding to the rotational speed probe at the moment; slowly and reversely rotating the rotational speed probe to the calculated number of turns; and positioning the rotational speed probe so as to finish installation. The method can meet the requirement of an installing gap without using a filler gauge, so that the design of rotary mechanical equipment is no longer limited by the space constraint that the filler gauge is needed to measure the gap between the rotational speed probe and the top of the tooth top of the gear when installing the rotational speed probe. Therefore, mechanical design and on-site installation become more flexible.

Referring to accompanying drawing, a kind of installation method of rotational speed probe of rotary machine comprises the following steps:
The first step is searched the product description of rotational speed probe 5, need to confirm the adjacent thread gap of the rotational speed probe 5 installed, and unit is mm,
The purpose of doing like this has three, and the one, confirm whether rotational speed probe 5 is selected correctly; The 2nd, made in Great Britain on the instructions or unit made in U.S.A are converted into mm unit, be convenient to calculate; The 3rd, this value is rotational speed probe 5 screw thread rotation the flexible value of pairing rotational speed probe 5 axial displacements when turning around is installed.
The assemblage gap code requirement of second step, rotational speed probe 5 is between the 0.5mm--1.2mm, and rotating cycle when selecting rotational speed probe 5 to install by the integral multiple calculating of 1/6 circle guarantees that it within the claimed range of assemblage gap standard, is preferably between the 0.8mm--1mm,
Because the tail end of rotational speed probe 5 is regular hexagon.This mainly is that manufacturer is for the ease of using mechanical wrench.So in the time of can calculating rotational speed probe 5 easily the integral multiple of rotation 1/6 circle or 1/6 circle is installed, whether the flexible value of corresponding axial displacement is in the scope between rotational speed probe 5 assemblage gap code requirement 0.5mm--1.2mm.For security of operation and the measuring accuracy that guarantees rotational speed probe 5, the flexible value of axial displacement of rotating cycle correspondence was selected between the 0.8mm--1mm when rotational speed probe 5 that is calculated was installed.Because rotational speed probe 5 installations are too low, when vibration takes place rotating machinery, may bump, thereby damage probe, and rotational speed probe 5 installations are too high, can have influence on measuring accuracy, even can't normally use with the gear teeth ogival.
The 3rd step, selects a rotational speed probe mounting hole 3 arbitrarily, seek and confirm that rotational speed probe hole 3 just aims at the gear teeth ogival, and the crown top is vertically corresponding to the centre of the probe hole on the casing 23 by manual jiggering,
Utilize flashlight lighting and the hard thing of feeler lever class to confirm whether the rotational speed probe hole 3 on front housing is just aimed at the gear teeth ogival, is and the crown top located substantially on the probe hole 3 vertical corresponding medium positions on the casing? if not, then need manually slow jiggering, thereby make the macro-axis of rotating machinery slowly rotate the driven gear rotation, simultaneously with flashlight lighting from the rotational speed probe hole 3 position of rotation that monitor the gear teeth ogivals, and when judging that rotational speed probe hole 3 and gear teeth ogival relative position are appropriate, stop jiggering, vertically insert probe hole 3 once more with the hard thing of feeler lever class, check the physical location situation at gear teeth ogival and 3 centers, rotational speed probe hole repeatedly by insertion depth, till judging that two conditions that the 3rd step required all satisfy.
The 4th step, rotational speed probe 5 rotated by hand be installed into the 3rd rotational speed probe hole 3 looked for of step, manually rotation is installed to till rotational speed probe 5 tops withstand with the gear teeth ogival, and the corresponding corresponding mark in any point position of rotational speed probe 5 and casing 2 at this moment,
At this moment, rotational speed probe 5 unrenewable hand-screws advance.The purpose of doing like this is neither to damage rotational speed probe 5 tops, can guarantee again between rotational speed probe 5 tops and the gear teeth ogival without any the gap.The purpose of certain corresponding mark in some positions that rotational speed probe 5 and casing 2 is corresponding is to stay the reference point of a reference position on casing 2, i.e. " zero " gap point.
The 5th step, with in the 4th step on casing 2 point of mark be reference point, with in the 4th step on rotational speed probe 5 point of standard be reference point, till the determined number of turns in rotational speed probe 5 backspins to the second steps,
The assemblage gap that this step just can be guaranteed rotational speed probe 5 is between the 0.5mm--1.2mm of code requirement in the scope.If reference point is taken to an orthohexagonal angle, so, can reach rotational speed probe 5 gaps fully at the gap of 0.8mm--1.0mm installation requirement.
The 6th goes on foot, rotational speed probe 5 is located, and install and finish,
After finished rotational speed probe 5 location, with two mechanical wrenches, one was used for the tail end of rotational speed probe 5 locked; Another clamps probe band hold-down nut 4, to fastening direction firmly, rotational speed probe 5 is fixed on casing 2 bodies.So far a rotational speed probe 5 is with regard to installation.
The 7th step, for the installation of second, the 3rd rotational speed probe 5, repeat above the 3rd to six step to get final product.
