Detailed Description
The invention is described in further detail below with reference to the following figures and detailed description:
as shown in fig. 1, 2, 3 and 4, the method for detecting the location degree of the circumferential hole on the end surface of the oversize bearing comprises a reference hole 1, a detected hole 2, a circumferential hole theoretical center circle 3, a plane coordinate system 4, a bearing outer diameter 5 and a bearing inner diameter 6; the reference hole 1 is a hole which is adjacent to the measured hole 2 and takes the measured hole 2 as a reference; the holes 2 to be measured are uniformly distributed on the circumference of a theoretical center circle 3 of the circumferential hole, and the center of the holes 2 to be measured is arranged on the Y axis of a plane coordinate system 4; the theoretical center circle 3 of the circumferential hole is a center circle of holes uniformly distributed on the end surface of the super-huge bearing along the circumference; the plane coordinate system 4 takes the center of the super-large bearing outer diameter 5 or the bearing inner diameter 6 as an origin, and establishes an XOY plane coordinate system which takes the Y axis to pass through the center of the measured hole 2.
Firstly, a theoretical drawing of a tested bearing is combined to determine theoretical values of the following parameters, and the embodiment takes the bearing inner diameter 6 as a reference example: the minimum distance h between the measured hole 2 and the reference hole 1, the minimum distance h1 between the measured hole 2 and the bearing inner diameter 6, and the included angle alpha between the center of the measured hole 2 and the center of the reference hole 1 and the connecting line of the centers of the theoretical center circles 3 of the circumferential holes respectively.
Then, the actual distance h ' between the hole 2 to be measured and the reference hole 1 is measured 3 times by a tool such as a caliper, the minimum value is obtained, and the distance h1' between the hole 2 to be measured and the bearing bore 6 is measured 3 times, the minimum value is obtained, and the actual distance deviation Δ 1 between the hole 2 to be measured and the reference hole 1 and the distance deviation Δ 2 between the hole 2 to be measured and the bearing bore 6 are calculated from the theoretical values, whereby h1' -h1 are obtained.
And finally, substituting the actual distance deviation delta 1 between the measured hole 2 and the reference hole 1 and the actual distance deviation delta 2 between the measured hole 2 and the bearing inner diameter 6 into a formula:
With reference to fig. 1, 2, 3 and 4, the derivation process of the formula of the oversize bearing end face circumferential hole position degree δ is as follows:
firstly, an XOY plane coordinate system which takes the center of the oversize bearing inner diameter 6 as an origin and passes through the center of the measured hole 2 by the Y axis is established.
1) In an XOY plane coordinate system, the center of a reference hole 1 is A, the center of a measured hole 2 is B, the actual center of the measured hole 2 is C, and BC is connected, so that the distance of BC is the position degree of the measured hole 2; connecting AC to Y axis at point F, connecting CO to theoretical center circle 3 of the hole at point H, making CE perpendicular to Y axis at point E, and making a point on AC to make AD equal to AB.
2) According to the analysis of fig. 1, 2 and 3, CE is the component (i.e. the deviation in the circumferential direction) of the measured hole position degree deviation BC in the X-axis direction; BE is the component (namely radial deviation) of the measured hole position deviation BC in the Y-axis direction; CH is the deviation delta 2 between the minimum distance h1 between the measured hole 2 and the inner diameter 6 of the oversize bearing and the theoretical minimum distance h 1'; the sizes of CO and EO are larger, and the included angle between the CO and the EO is very small and approaches to 0 degrees, so BE is approximately equal to CH (delta 2); and because the deviation BC of the position degree of the measured hole is very small relative to the theoretical distance AB between two holes, the & lt CAB is also very small, the & lt CAB is regarded as & lt 0 degrees, then & lt ABD & lt ADB & gt 90 degrees, then & lt BFD & lt CFE & lt beta & lt ABO & lt (180-alpha)/2 & lt (90-alpha/2), and because AD & lt AB, CD is the deviation Delta 1 between the actual minimum hole distance h and the theoretical minimum hole distance h' of the measured hole 2 and the reference hole 1.
3) Further analysis and derivation, let CE ═ a, EF ═ b, CF ═ c, BD ═ a ', DF ═ b ', BF ═ c ', β ═ 90 ° - α/2; let BC BE δ, CD Δ 1, BE Δ 2; then according to the triangular pythagorean theorem
In conjunction with the geometric relationships in fig. 3, b ═ c × cos β, b ' ═ c ' × cos β, CD ═ b ' + c Δ 1, and BE ═ b + c ═ Δ 2, we derive:
and the component of BC in the X-axis direction is CE,
wherein: CE ═ a ═ c × sin β, c ═ CF ═ CD-DF ═ Δ 1-b ═ Δ 1-c' × cos β,
c’＝BE-b＝Δ2-c×cosβ，
and (3) pushing out: c ═ Δ 1- (Δ 2-c × cos β) × cos β
c＝Δ1-Δ2×cosβ+c×cosβ2
Therefore:
i.e. the circumferential deviation of the hole 2 to be measured.
Further deducing a position degree formula of the detected hole 2:
in the formula
The deviation of the hole 2 in the circumferential direction is measured, delta 2 is the radial deviation of the measured hole 2, alpha is the included angle between the connecting line of the center of the measured hole 2 and the center of the reference hole 1 and the circle center of the theoretical center circle 3 of the circumferential hole, and the deviation of the position degree of the hole can be calculated according to the formula.
