We can provide free samples . Please contact Email for any inquiries
Define the Set-Right ? Technology: through the control of the assembly tolerance value of variables and by using the theory of probability and statistics theory, the tapered roller bearing clearance at 99.73% clearance value required in the assembly, adjust the clearance process to avoid the extra. This part covers the probability theory, statistics principle, calculation of dimension chain and the Six Sigma Lean Production concept. The technology for decades has been used by many customers, has been widely used in the field of automobile wheel end, industrial gearbox,
engineering mechanical force taking device etc.. Compared with the traditional method of adjusting the clearance, its advantages are as follows:
1 reduce manpower cost production line and technology ability of expenditure
No need to match 2 of all the assembly of components, can realize fast, accurate assembly, the most suitable for mass production
3 avoid assembly field data measurement and adjustment procedure
Special equipment and 4 workers without clearance for the adjustment fixture
5 is cancelled clearance adjustment of conventional gaskets and other parts
Maintenance of 6 customer service market more easily, quickly and accurately
The following describes the principle and application method of Set-Right ? technology.
A, Set-Right ? principle
Bearing, bearing system of shaft, bearing seat, a spacer ring and other components have their own design tolerance, in the production process and manufacture error due to equipment, materials, personnel and environment factors, the manufacturing error of qualified products to fluctuations in the tolerance range of the minimum and maximum values.
