The outer guide ring plays a role in supporting the inner ring of the bearing; the control ring is equal to the bearing outer ring and transmits the radial load of the servomotor to push the guide vane switch; the compression ring has the same action with the retainer and forms a magazine together with the control ring and the outer guide ring; the steel ball is equal to the ball of the ball bearing and is used for supporting the outer guide ring and the control ring, and the friction between the control ring and the outer guide ring can be reduced by arranging the steel ball when the control ring rotates.

The control ring and the pressure ring of the water distributor of the through-flow turbine are of an integral structure, and the water distributor can generate mechanical abrasion after running for a certain time and needs to be dismantled, maintained and repaired. Dismantle the clamping ring alone, the steel ball can drop because of self gravity, easily leads to constructor injured and injures adjacent equipment by a crashing object, must wholly tear open when dismantling and hang water distributor, and the maintenance processing time is long, and the degree of difficulty is big, and the maintenance cost is high. Meanwhile, the maintenance period is long, the total power generation output of the power station is limited, the labor intensity is improved, and the potential safety hazard is increased. After the original equipment structure is adopted for reloading, the running conditions of the steel balls and the bearing grooves cannot be visually observed in the normal running process of the unit, and the tracking and the maintenance of hidden troubles of the equipment are not convenient.

The utility model aims at providing a locate water turbine water distributor control ring's bullet window hole structure for solving above-mentioned problem.

In order to achieve the purpose, the present disclosure provides a pop-up window hole structure arranged on a control ring of a water turbine water distributor, wherein a bearing groove is arranged on an outer ring surface of an outer guide ring of the water distributor, the control ring of the water distributor is arranged outside the outer guide ring, a steel ball is arranged in the bearing groove, the control ring is rotatably connected with the outer guide ring through the arrangement of the steel ball, the pop-up window hole structure comprises a pop-up window hole, a pop-up window hole for loading or taking out the steel ball is arranged on the control ring, the pop-up window hole penetrates through the control ring, and a central axis of the pop-up window hole is positioned on the same straight line with a circle center.

The beneficial effects of the utility model reside in that:

the utility model relates to a bullet window hole sets up on the control ring, under the condition of hanging water distributor not tearing open, can repair and change the steel ball to outer guide ring, control ring and clamping ring. The bearing groove and the steel ball of the hidden device can be conveniently, concisely and quickly tracked and detected through the unit compression ring elastic window hole in an unscheduled mode, the change trend of the device is found, a basis is provided for reasonably arranging the overhaul period of the device, and the safe and stable operation of the device is guaranteed. The scheme can improve the safe and stable operation capacity of the unit, provides data support for the operation maintenance reliability of the unit, shortens the maintenance construction period, reduces the maintenance cost and increases the generating capacity of the unit.
