Abstract
The utility model discloses a crank arm rotating shaft for an isolating switch. The crank arm rotating shaft comprises a rotating shaft, wherein a cylindrical groove is axially formed at the outer end of the rotating shaft; part of the section or the entire section of the groove adopts a threaded hole structure from outside to inside; an oil sealing cover is in threaded connection with the threaded section of the groove; a cotter pin for preventing the oil sealing cover screwing out is axially arranged on the outer side of the rotating shaft; at least one oil hole communicated with the groove is axially formed on the inner side of the rotating shaft; and a cross-shaped groove or a horizontal groove for the screwing of a screw driver is formed at the external end of the oil sealing cover. By adopting the crank arm rotating shaft with a simple structure and easiness in manufacture and mounting, the rotating shaft and a circular ring can always be in a lubricated state, so that the rotating shaft is prevented from rust completely, and a power supply system can operate normally.
Description
Technical field
The utility model relates to a kind of electric equipment parts, is specifically related to a kind of isolating switch connecting lever rotating shaft.
Background technology
Isolating switch is the important electric equipment of electric power system, purpose is to form tangible cut-off point, because isolating switch does not often use, often because the connecting lever rotating shaft of isolating switch and being enclosed between the annulus in the rotating shaft is got rusty, cause rotating shaft not rotate in the time of need operating, isolating switch can not normal deciliter, influence normally stops to send, particularly the isolating switch connecting lever rotating shaft of the bus bar side especially severe that gets rusty is difficult to have a power failure, and badly influences the normal operation of electric power system.
The utility model content
The utility model provides a kind of antirust isolating switch connecting lever rotating shaft in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the rotating shaft of isolating switch connecting lever, comprise rotating shaft, described rotating shaft outer end is axially arranged with columned groove, the groove ecto-entad has one section or complete section to be screwed hole, be bolted with an oil seal cover in the thread segment of groove, the rotating shaft outer radial is provided with the split pin that prevents that oil seal cover from screwing out, and the rotating shaft inboard radially is provided with at least one oilhole that is communicated with groove.
Described oil seal cover outer end is provided with cross recess or the flat recess that turns with screwdriver.
Adopt said structure, rotating shaft outer circumference and annulus are rotatably assorted, in groove, inject a certain amount of lubricating oil by the rotating shaft outer end, oil seal cover seals groove, inserting split pin not only prevents the oil seal cover back-out and causes leakage of oil, and playing the outer axially movable effect of annulus of positioning rotating shaft, the lubricating oil in the groove penetrates into mating surface between rotating shaft and the annulus by at least one oilhole, thereby has avoided often not operating rotating shaft for a long time and make the get rusty generation of phenomenon of rotating shaft and annulus.The utility model is simple in structure, be easy to make and install, make to be in lubricating status between rotating shaft and the annulus all the time, stopped the get rusty generation of phenomenon of rotating shaft fully, reaches the purpose of the normal operation of electric power system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, isolating switch connecting lever of the present utility model rotating shaft, comprise rotating shaft 1, rotating shaft 1 outer end is axially arranged with columned groove 2, groove 2 ecto-entads have one section or complete section to be screwed hole, be bolted with an oil seal cover 3 in the thread segment of groove 2, rotating shaft 1 outer radial is provided with the split pin 4 that prevents that oil seal cover 3 from screwing out, and rotating shaft 1 inboard radially is provided with at least one oilhole 5 that is communicated with groove 2.Oil seal cover 3 outer ends are provided with cross recess or the flat recess 6 that turns with screwdriver.
When work is used, rotating shaft 1 outer circumference and annulus (not shown) are rotatably assorted, in groove 2, inject a certain amount of lubricating oil by rotating shaft 1 outer end, use screwdriver to hold out against cross recess or flat recess 6, oil seal cover 3 is screw into sealed groove 2 in the groove 2, inserting split pin 4 not only prevents oil seal cover 3 back-outs and causes leakage of oil, and play the outer axially movable effect of annulus of positioning rotating shaft 1, lubricating oil in the groove 2 penetrates into mating surface between rotating shaft 1 and the annulus by at least one oilhole 5, thereby has avoided often not operating rotating shaft 1 for a long time and make the get rusty generation of phenomenon of rotating shaft 1 and annulus.
Claims (2)
