Abstract
The utility model discloses a motor operation mechanism for high-voltage isolating switch used in the high voltage isolator, which consists of a motor, a retarding mechanism, a bracket, a control circuit apparatus, a wire connecting terminal, a pilot switch, a control crank and a tank. The retarding mechanism comprises a totally sealed gear reduction unit and a totally sealed worm reducer, and a connecting plate is applicable to combine the gear reduction unit and the worm reducer by the tighter. The utility model has the advantages of low noise, high credibility and the mechanical part maintenance free.
Description
The utility model relates to a kind of motor operating mechanism that is used for high voltage isolator branch, closing operation.
Motor operating mechanism commonly used at present such as CJ2-XG, CJ5, CJ6, CJ7 type motor operating mechanism have all adopted the design of decelerator unenclosed construction.This construct noise is big, poor lubrication, driving parts lost efficacy poor reliability, maintenance difficult easily.Thereby bring hidden danger for the normal operation of transformer station.
The purpose of this utility model is to provide the product that a kind of noise is little, reliability is high, mechanical part is non-maintaining for power supply department.
For achieving the above object, the utility model adopts following technical scheme: the large speed ratio reducing gear of motor operating mechanism is made up of two parts: a part is the worm reducer of all-sealed structure, another part is the gear reduction unit of all-sealed structure, these two parts are linked together with securing member by a gusset piece.
The utility model is owing to adopted gear reduction unit and the mode of worm reducer combination, both having solved the motor operating mechanism needs the difficult problem of large speed ratio, accomplished to adopt hermetic structure again, thereby reached that the driving member lubricating condition is good, noise is low, reliable operation, mechanical part be non-maintaining.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model reducing gear structural representation.
As shown in Figure 1, the utility model is made of motor 4, reducing gear 5, support 8, control apparatus, crank 7, casing 3, connecting lever 42 etc.Reducing gear 5 can be rack-mount, also can be an individual components that is separated with support 8, is made of the worm reducer that is full-closed structure and gear reduction unit two parts.Both inside all are filled with lubricating oil, are linked together with securing member by a gusset piece.The gear reduction unit of reducing gear can replace with the cycloidal-pin wheel decelerator, it both can make an integral body with motor, also can be split up into two parts with motor, present embodiment motor and gear reduction unit are made of one, and it is connected as a single entity by screw rod or other securing member and gear box.
The concrete structure of reducing gear as shown in Figure 2.Gear reduction unit is made of gear shaft 16, gear 21, gear 22, gear 39, gear box 23.Gear shaft 16 is fixed on the adjacent tank wall of gear box 23 and motor 15 by bearing 17, with motor reel be same axis, the one end is meshed with gear 21.Gear 22 is coaxial with gear 21, and is meshed with gear 39, and two gears are fixed on the gear box tank wall by two bearings 20 respectively.39 of gears are fixed on the gear box tank wall by bearing 38, and its rotating shaft 35 1 ends stretch out gear box and enter in the worm gear case, and are connected as a single entity by the worm screw 29 of key 34 with worm reducer.Worm reducer is made of intermeshing worm gear 28, worm screw 29 and worm gear output shaft 33 and worm gear case, the two ends of worm screw 29 are fixed on the inwall of worm gear case by bearing 26 and 30 respectively, worm gear output shaft 33 two ends are all stretched out outside the worm gear case, the upper end is used for being connected with the main shaft of isolating switch, the lower end links to each other with connecting lever 42, is used to control the limit switch 9 and the auxiliary switch 2 of control apparatus.All be filled with lubricating oil in the gear box of gear reduction unit and the worm gear case of worm reducer, both are connected as a single entity by gusset piece 24 usefulness bolts or other securing member.In order to prevent leakage of oil, bearing 17,26,30,38 all is furnished with oil sealing 18,36,31 and 37 respectively.
Control apparatus of the present utility model comprises actuating button 1, auxiliary switch 2, limit switch 9, thermal relay 10, contactor 11, miniature circuit breaker 12, binding post 13, goes out formations such as wire loop 14, the annexation of its each components and parts and control principle and the prior art control apparatus of CJ2-XG type motor operating mechanism as the aforementioned are identical, do not give unnecessary details at this.
