Abstract
The utility model relates to a kind of submersible water impeller wheel skidding device.It comprises support, support has the pivot shaft in horizontal arrangement, and the two ends of pivot shaft all reach outside support.That section of pivot shaft outside support all there is screw thread, equal limited location nut on screw thread.That section of pivot shaft in support there is wheel disc, the periphery of wheel disc has the steel rope race along its circumference.Be characterized in being linked together by antifriction-bearing box between described wheel disc and pivot shaft.The service life of wheel skidding device is longer, not easily produces stuck.
Description
Technical field
The utility model relates to a kind of wheel skidding device, is used to the submersible water impeller wheel skidding device of rising or decline submersible water impeller main body specifically.
Background technology
All know at sewage treatment area, submersible water impeller needs the action carrying out rising or declining when disposing of sewage, this all realizes by means of wheel skidding device.
At present, the submersible water impeller wheel skidding device used in industry comprises support, and support has the pivot shaft in horizontal arrangement, the two ends of pivot shaft all reach outside support.That section of pivot shaft outside support all there is screw thread, equal limited location nut on screw thread.That section of pivot shaft in support is connected with wheel disc by plain bearing, the periphery of wheel disc has the steel rope race along its circumference.Linked together by plain bearing between the wheel disc of traditional wheel skidding device and pivot shaft, make to rotate in sliding type between wheel disc and pivot shaft, the friction force rotated due to sliding type is large, the wearing and tearing of pivot shaft are larger, reduce the service life of wheel skidding device, and the wearing and tearing of pivot shaft are comparatively large, can make between wheel disc and pivot shaft, to occur eccentric phenomenon, easily cause wheel disc stuck.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of submersible water impeller wheel skidding device, and the service life of this wheel skidding device is longer, not easily produces stuck.
For solving the problem, provide following technical scheme:
Submersible water impeller wheel skidding device of the present utility model comprises support, support has the pivot shaft in horizontal arrangement, and the two ends of pivot shaft all reach outside support.That section of pivot shaft outside support all there is screw thread, equal limited location nut on screw thread.That section of pivot shaft in support there is wheel disc, the periphery of wheel disc has the steel rope race along its circumference.Be characterized in being linked together by antifriction-bearing box between described wheel disc and pivot shaft.
It is all flexible back-up ring on the pivot shaft being positioned at wheel disc both sides to further improvement of the utility model scheme.The advantage of such improvement utilizes circlip to make to keep certain spacing between wheel disc and support, thus make wheel disc not easily encounter support in rotation process, reduce further wheel disc and produce stuck possibility.
Take above scheme, have the following advantages:
Owing to being linked together by antifriction-bearing box between the wheel disc of submersible water impeller wheel skidding device of the present utility model and pivot shaft.So rotate in roller between wheel disc and pivot shaft, friction force is less, less to the wearing and tearing of pivot shaft, thus improve the service life of this wheel skidding device, and pivot shaft wearing and tearing are less, make between wheel disc and pivot shaft, not easily to occur eccentric phenomenon, greatly reduce wheel disc and produce stuck possibility.
Accompanying drawing explanation
Fig. 1 is the structural representation of submersible water impeller wheel skidding device of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, submersible water impeller wheel skidding device of the present utility model is described in further detail.
As shown in Figure 1, submersible water impeller wheel skidding device of the present utility model, comprises support 1, support 1 has the pivot shaft 5 in horizontal arrangement, and the two ends of pivot shaft 5 all reach outside support 1.That section of pivot shaft 5 outside support 1 all there is screw thread, equal limited location nut 6 on screw thread.That section of pivot shaft 5 in support 1 there is wheel disc 2, all flexible back-up ring 7 on the pivot shaft 5 being positioned at wheel disc 2 both sides.The periphery of described wheel disc 2 there is the steel rope race 3 along its circumference, linked together by antifriction-bearing box 4 between wheel disc 2 and pivot shaft 5.
During use, first, one end of steel rope is connected submersible water impeller main body, and the other end of steel rope twines on the steel rope race 3 on wheel disc 2; Then, rotating wheel disk 2 can rise or decline submersible water impeller main body.
