Abstract
The utility model discloses an assembly structure of breaker main shaft and turn arm in a switching device of an electric distribution system, wherein a corresponding one of a main shaft spline (1) and a turn arm spline (3) is used as a reference spline, a boss (2) is made on the main shaft spline (1), and a corresponding groove (4) shape or a rectangular groove is arranged on the turn arm spline (3). When assembling the assembly structure of breaker main shaft and turn arm, the location is accurate, the assembly position of the turn arm is easily identified, errors of the assembly are reduces, and the assembly is simple, convenient and rapid.
Description
Technical field
The utility model relates to a kind of circuit breaker main shaft in the electrical power distribution system switchgear and the assembly structure of connecting lever.
Background technology
In circuit breaker design, the relative position between connecting lever and main shaft is very accurate, and it is related to the mechanical property and the stability of the performance of circuit breaker own, so the assembling of main shaft and connecting lever seems particularly important.At present, adopt splined between circuit breaker main shaft and the connecting lever mostly, owing to the spline cross section is centrosymmetric, so when the assembling connecting lever, be easy to the wrong location.
The utility model content
The purpose of this utility model be design a kind of assembling simply, circuit breaker main shaft and connecting lever assembly structure efficiently.
The technical scheme that the assembly structure of the utility model circuit breaker main shaft and connecting lever adopts is: according to the set parameter of design, on the rectangular spline of main shaft and connecting lever, choose a corresponding key respectively as reference key, on the spline of main shaft, do a boss, on the spline of connecting lever, do a corresponding groove.
This circuit breaker main shaft and connecting lever assembly structure location when assembling accurately is easy to distinguish the rigging position of connecting lever, reduces the assembling error, assembles simple, convenient, fast.
Description of drawings
Fig. 1 is the structural representation of existing circuit breaker main shaft and connecting lever assembly structure main spindle multiple spline;
Fig. 2 is the main TV structure schematic diagram of existing circuit breaker main shaft and the disconnected connecting lever of connecting lever assembly structure;
Fig. 3 is the main spindle multiple spline structural representation of a utility model circuit breaker main shaft and an embodiment of connecting lever assembly structure;
Fig. 4 is the connecting lever structural representation that assembles with main spindle multiple spline embodiment illustrated in fig. 3;
Fig. 5 is main shaft of the foregoing description and the spline cross section sectional structure schematic diagram after the connecting lever assembling.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, main spindle multiple spline 2, boss 3, connecting lever spline 4, groove 5, connecting lever
As Fig. 3, Fig. 4, shown in Figure 5, the utility model circuit breaker main shaft and connecting lever assembly structure are provided with boss 2 on main spindle multiple spline 1, and connecting lever spline 3 is provided with groove 4.
As long as firmly believe boss 2 and groove 4 during assembling, just can accurately assemble connecting lever 5.Because the position of boss and groove is determined according to the designer, can effectively guarantee design philosophy, does not need special positioning tool.Can reach and assemble purpose accurately and fast.
Claims (1)
1, a kind of circuit breaker main shaft and connecting lever assembly structure, comprise main spindle multiple spline (1) and connecting lever spline (3), it is characterized in that: according to the set parameter of design, at main spindle multiple spline (1) and connecting lever spline (3) is reference key with a corresponding key upward, on main spindle multiple spline (1), do a boss (2), on connecting lever spline (3), do a corresponding groove (4).
