Description
Technical Field
The invention relates to a method for assembling qualified bearings by matching an inner ring, an outer ring and steel balls of an angular contact ball bearing, and belongs to the technical field of bearing matching.
Background
The protrusion is an important parameter of a high-precision angle contact bearing, and generally has a relatively small tolerance band. The inner ring and the outer ring of the same sleeve are assembled by using steel balls with different gauges, so that different protrusion amounts can be obtained, namely, the qualified protrusion amount can be obtained by adjusting the gauges of the steel balls.
The method for selecting the proper gauge value of the steel ball of the existing angular contact ball bearing comprises the steps of firstly assembling a set of bearing by using a 0# steel ball and an inner ring and an outer ring to be tested, then measuring the protrusion amount of the bearing, disassembling the bearing after the measurement is finished, taking out the 0# steel ball and recycling the 0# steel ball. And calculating the steel gauge value to be used according to the difference value between the measured protrusion amount and the qualified protrusion amount and the known proportional relation determined by the contact angle.
In the method, the 0# steel ball used for each measurement needs to go through the processes of sleeve assembling, measuring and sleeve disassembling, the efficiency is low, the sleeve assembling and sleeve disassembling processes are complex, and the full-automatic operation can be completed by means of a robot, so that the manufacturing cost of process equipment for realizing the process is high, and the efficient mass production of the bearings is not facilitated.
Disclosure of Invention

The invention discloses a method for selectively matching protrusion amount of an angular contact ball bearing, which comprises the following steps:
(1) The inner ring and the outer ring of the qualified angular contact ball bearing with the same model are called as a female ring, and the width H0 of the female ring is measured (the width of the inner ring and the outer ring of the female ring is equal to each other);
(2) Measuring the width H1 of a measured piece (the widths of the measured inner ring and the measured outer ring are equal);
(3) Sleeving the inner ring of the female ring and the outer ring of the female ring by using a No. 0 gauge steel ball, and measuring the protrusion T0 of the female ring;
(4) Measuring the protrusion Tw1 of the inner ring of the female ring and the measured outer ring by using the inner ring of the female ring and a 0# gauge steel ball;
and (3) placing the steel balls with the gauge value of 0# on the female ring inner ring as a whole (only the female ring outer ring in the fitting in the step (3) is removed), fitting the tested outer ring and the female ring inner ring, and measuring to obtain the protrusion Tw1 of the female ring inner ring and the tested outer ring.
(5) Measuring the protrusion Tn1 of the outer ring of the female ring and the inner ring to be measured by using the outer ring of the female ring and a 0# gauge steel ball;
and (3) placing the steel balls with the gauge value of 0# in the outer ring of the female ring as a whole (only the inner ring of the female ring in the fitting in the step (3) is removed), fitting the outer ring to be measured and the inner ring to be measured, and measuring to obtain the protrusion Tn1 of the outer ring of the female ring and the inner ring to be measured.
(6) According to the measured values, the protrusion T1 of the measured piece is calculated, and the calculation formula is as follows: t1= (Tw 1+ Tn1+ H0) - (T0 + H1).
That is, the final required protrusion amount T1 of the tested piece is equal to the sum of the protrusion amount Tw1 of the inner ring and the outer ring of the mother ring, the protrusion amount Tn1 of the outer ring and the inner ring of the mother ring and the width H0 of the mother ring minus the sum of the protrusion amount T0 of the mother ring and the width H1 of the tested piece.
According to the data of the protrusion T1 of the tested piece, a proper steel ball gauge value can be selected to ensure that the protrusion meeting the requirement is obtained.
According to the method, the width H0 of the female ring and the width H1 of the measured piece can be measured independently (without sleeve combination), and the numerical value T0 can be measured only by sleeve combination of the 0# gauge steel ball, the female ring inner ring and the female ring outer ring. When Tw1 is measured on the measured outer ring, the inner ring of the female ring and the 0# gauge steel ball are integrated, and the measured outer ring and the 0# gauge steel ball are only sleeved with each other without detaching the 0# gauge steel ball. When the Tn1 is measured on the measured inner ring, the outer ring of the female ring and the 0# gauge steel ball are integrated, and the measured inner ring and the 0# gauge steel ball are sleeved only and do not need to be detached.
The invention introduces the concept of the female ring, the inner ring and the outer ring of the angular contact ball bearing with the same model are called as the female ring, the protrusion amount of the inner ring and the outer ring of the female ring is respectively measured, then the protrusion amount of the measured piece is calculated, and the proper gauge value of the steel ball is selected according to the protrusion amount, so that the 0# steel ball does not need to be frequently disassembled, the process is simple and convenient, the efficiency is greatly improved, and the automatic measurement is convenient to realize.

Referring to fig. 1, 2 and 3, the suffix of the character in the figure is 0 to represent the mother ring parameter, and the suffix of the character is 1 to represent the measured piece parameter; the meaning of each symbol in the figure is:
t0: the amount of protrusion of the female ring is increased,
h0: the width of the female ring is that,
nd0: the distance from the large end surface of the female ring inner ring 1 to the center of the sphere,
wd0: the distance from the big end surface of the female ring outer ring 2 to the center of the sphere,

selecting and matching the protrusion T1 of the tested piece according to the following process:
1. the widths H0 of the inner ring 1 and the outer ring 2 of the female ring are measured, see fig. 1. The process is only required to be performed once, and the required parameters are obtained.
2. The widths H1 of the measured inner ring 4 and the measured outer ring 5 are measured.
3. And (3) sleeving the female ring inner ring 1 and the female ring outer ring 2 by using a 0# gauge steel ball 3, and measuring the numerical value of the female ring protrusion amount T0. See fig. 1. The process only needs to be performed once, and the required parameter T0 can be obtained.
4. Referring to fig. 2, the protrusion Tw1 of the measured outer ring 5 is measured using the inner ring 1 of the mother ring and the 0# gauge steel ball 3

6. According to the measured values, the projection amount T1 of the measured piece is calculated
The formula is T1= Wx1+ Nx1-H1,
because: t0= H0- (Nd 0+ Wd 0), so Nd0+ Wd0= H0-T0,
Wx1＝Nd0+Tw1，
Nx1＝Wd0+Tn1，
so that:
T1＝(Nd0+Tw1)+(Wd0+Tn1)-H1
＝(Nd0+Wd0)+(Tw1+Tn1-H1)
＝(H0-T0)+(Tw1+Tn1-H1)
＝(Tw1+Tn1)+(H0-T0-H1)
＝(Tw1+Tn1+H0)-(T0+H1)。
