A kind of ball rotational structure for aircraft engine disk hole position gauge turntable of manufacturing cost.
For this purpose, the utility model provides a kind of ball rotational structure for aircraft engine disk hole position gauge turntable,
It includes ball rotating mechanism, and ball rotating mechanism is installed between turntable and pedestal, and the first flange collar is formed on the bottom of turntable, the
The first mounting groove is formed in one flange collar, the second flange collar is formed on the top of pedestal, and the second mounting groove, the first peace are formed in the second flange collar
Tankage and the second mounting groove constitute internal installation space, and ball rotating mechanism includes multiple roller bearing rotating units, and multiple roller bearings turn
Moving cell is distributed in the space between the first flange collar and the second flange collar along the circumferential direction of turntable and pedestal, roller bearing rotating unit tool
There is ball body.
Further, the circumferentially uniformly distributed axis body of multiple turntables and pedestal, axis are also equipped in above-mentioned internal installation space
Body is arranged in the inside of the first flange collar and the second flange collar.
Further, above-mentioned axis body is eccentric shaft.
Further, above-mentioned axis body is bolted to connection in the slot bottom of the second mounting groove.
Further, the ring edge position of above-mentioned first flange collar has the first convex edge extended into the first flange collar.
A kind of ball rotational structure for aircraft engine disk hole position gauge turntable provided by the utility model, phase
Mainly have the advantage that by using ball and its supporting structure that substituting traditional bearing is turned compared with the prior art
Dynamic, since the structure of ball is simple, replacement is more quick, thus can effectively simplify installation and subsequent maintenance work, together
When reduce manufacturing cost.
