Technical explanation of the tolerance value of the shaft hole of the large-hole coupling

Large hole couplingThe tolerance value of the shaft hole is explained by the machinery factory. The standard tolerance is only representative of the majority, in general!Nowadays, with the rapid development of science and technology, product equipment has also been diversified and changed!There are some devices that prohibit high temperature (greater than 30 degrees) so they are connected with holesCouplingJust produce according to the upper difference, use the press to install, some equipment is afraid of impact or external force knocking, such a shaft hole should be in a sliding fit state!The instance company produced a set last yearPin couplingThe inner hole is 500 mm, and the customer needs to provide hot mounting, then the technology is designed to reduce 0.2-0.3 mm, and the customer’s installation temperature is preferably 150 degrees!The products of the machinery factory work smoothly!Customer's praise!
