Description
Technical Field
The utility model relates to a spring operating mechanism, concretely relates to spring operating mechanism's motor reducing gear box assembly.
Background
The spring operating mechanism is a matched device suitable for switching on and switching off of a high-voltage load switch-fuse combined electrical appliance, the mechanism adopts a planar spiral spring energy storage control composite switch to switch on and off, three operating stations of switching on and switching off and grounding are arranged at a working position, the spring operating mechanism also has a five-prevention interlocking function, and the reliability is high when the spring operating mechanism is combined with a circuit breaker mechanism for use. Current spring operating device includes the framework, the switching-on operation axle that rotates to set up on the framework, the spiral spring energy storage subassembly of setting on the framework, the five-prevention interlocking subassembly of setting on the framework, the electric drive subassembly of setting on the framework, the structural design of the electric drive subassembly of current spring operating device is unreasonable, the reducing gear box of current electric drive subassembly adopts open structure, lubricating grease can't be deposited, lubricating grease consumes almost easily, thereby it is great to cause the wearing and tearing of the gear in the reducing gear box, the life of this reducing gear box has been shortened greatly. And the motor reduction gearbox assembly of the spring operating mechanism has the defects of complex structure, unreliable performance and short service life.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance are reliable, long service life's spring operating mechanism's motor reducing gear box assembly.
In order to achieve the above object, the utility model discloses a spring operating mechanism's motor reducing gear box assembly, including support, the motor of setting on the support, with motor linkage complex turbine speed reduction subassembly, turbine speed reduction subassembly including setting up casing, the turbine subassembly of setting in the casing on the support, the casing include the base, set up the lid on the base, base and lid between be formed with the holding chamber that is used for placing turbine subassembly, turbine subassembly including set up in the holding intracavity and with motor linkage complex worm, set up at the holding intracavity and with worm engaged with turbine, turbine and closing operation axle between be provided with clutch assembly.
The beneficial effect of above-mentioned structure is: the turbine assembly sets up in the casing, can deposit lubricating grease in the casing, and lubricating grease can play the lubrication action to the turbine assembly, can reduce the wearing and tearing of turbine assembly, is favorable to prolonging the life of this motor reducing gear box. And the motor reduction gearbox assembly has the advantages of simple structure, stable and reliable performance and long service life.
Particularly, the clutch assembly comprises a swing cam and two pawls, the swing cam is arranged in an accommodating groove of the turbine and is in linkage fit with the closing operation shaft, the two pawls are rotatably arranged in the accommodating groove of the turbine and are matched with the swing cam, the two pawls are symmetrically arranged on a positioning shaft in the accommodating groove, and a support spring is arranged between the two pawls and the positioning shaft. The clutch assembly is arranged between the turbine and the closing operation shaft, and can prevent the closing operation shaft from driving the turbine to rotate reversely during manual operation, and prevent the motor from being damaged due to reverse rotation, so that the service life of the motor reduction gearbox assembly can be prolonged.
