Description

Calibers for controlling shafts are called staples. You can use calibers to determine the suitability of the part. They do not allow measuring the actual size of the product, but only make it possible to establish that the product did not exceed the limit deviations. Limit gauges control the validity of the largest and smallest limit size of the part element. Such calibers are divided into passing and impassable. Pass caliber-bracket is used to control the validity of the largest limit shaft size. This size is suitable if the bracket has passed through it. Impassable caliber-bracket controls the validity of the smallest limit shaft size. This size is suitable if the impassable bracket has not passed through it. If the passing bracket passed, and the impassable bracket did not pass through the shaft, then it is believed that the actual shaft size is within the tolerance field Td and this shaft is suitable. Each gauge shall have: nominal shaft diameter; designation of shaft tolerance field; numerical values of limit deviations of the shaft; designation of the purpose of the caliber; trademark of the manufacturer.
