Embodiment
Further narrate the utility model below in conjunction with embodiment and accompanying drawing thereof:
A kind of soft starter for motor device (referring to Fig. 1-3) of the utility model design comprises casing and interior 2K-H type planet circular system and clutch and hydraulic system thereof; It is characterized in that described clutch by moving plate support 5, still supports 8, a 3-15 movable friction plate 12, a 3-15 static friction sheet 11, piston 7, piston cylinder 10 and back-up ring 6 are formed, wherein moving plate supports 5 and is connected by spline with described movable friction plate 12, described static friction sheet 11 supports 8 with still and also is connected by spline, described moving plate supports 5 and is connected with back-up ring 6 by screw, piston cylinder 10 supports 8 by screw and still and is connected, piston 7 can move reciprocatingly in piston cylinder 10, and described still support 8 is fixed with casing; Connected by link 4 between described 2K-H type planet circular system and the clutch components, be connected with ring gear 3 by screw link 4 left sides, link 4 right sides are supported 5 with moving plate and are connected; The hydraulic oil pipeline of described hydraulic system is leaded up to the oilhole that still supports 8 belows and is led between movable friction plate 12 and the static friction sheet 11, and piston 7 places are led to by the oilhole that still supports 8 tops in another road.
Described 2K-H type planet circular system is a prior art.It is made up of sun gear 16 and three planetary gears 14 and ring gear 3, planet carrier 15, and wherein planetary gear 14 is connected with planet wheel spindle 13, and power shaft 1 and sun gear 16 are connected by key, and planet carrier 15 and output shaft 9 are connected by key.Connected by link 4 between described 2K-H type planet circular system and the clutch components, its left side and described ring gear 3 are connected by screw, and its right side and moving plate support 5 are connected by also screw.Movable friction plate 12 described in the utility model and static friction sheet 11 embodiment respectively are 9.Movable friction plate 12 and static friction sheet 11 quantity how much depend on the requirement of transmitting power.
Described hydraulic system also is a prior art.It is mainly connected to form by pipeline by fuel tank 21, oil filter 22, overflow valve 23, pressure meter switch 24, Pressure gauge 25, solenoid directional control valve 26, flow control valve 27, vane pump 28, cleaner 29 and liquid level gauge 30 etc.Described hydraulic system is connected by oil pipe with described clutch, makes hydraulic oil lead up to the oilhole that still supports 8 belows and leads between movable friction plate 12 and the static friction sheet 11, and piston 7 places are led to by the oilhole that still supports 8 tops in another road.
The utility model soft starting device utilizes liquid viscosity transmission (Hydroviscous drive) form, it utilizes the oil-shear active force that is present between static friction sheet 11 and the movable friction plate 12 to come transferring power, it is combined with 2K-H type planet circular system, in the device start process, can realize the infinitely variable speeds between power shaft 1 and the output shaft 9, it can realize that the zero load of motor starts, and controllably progressively overcomes the inertia of whole system and start reposefully under the situation of heavy duty.For heavy mechanical equipment; " soft start " not only can alleviate the suffered startup of drive system itself significantly and impact; prolong the useful life of key components and parts; can also shorten simultaneously the attack time of motor start-up electric current greatly; reduce to the thermal shock of motor load and to the influence of electrical network; thereby saves energy and the working life that prolongs motor; and, therefore realized overload protection function when overload to drive system because static friction sheet 11 and movable friction plate 12 can relatively rotate.
Operation principle of the present utility model is: when using structure of the present invention, supply hydraulic oil by hydraulic system by the oilhole that still supports 8 belows earlier, under the fluid pressure effect, static friction sheet 11 and movable friction plate 12 are separated from each other.This moment, main driven by motor power shaft 1 rotated, because static friction sheet 11 and the liquid viscous force between the movable friction plate 12 on the clutch components are minimum and independently of one another, ring gear 3 is in free rotation state substantially, mechanism freedom is 2, and therefore the planet carrier 14 that links to each other with output shaft 9 remains static substantially.After treating that main electric motor starting steadily, solenoid directional control valve 26 commutations, hydraulic system supports the oilhole of 8 tops for hydraulic oil by still, exert pressure to piston, adjust the piston pressure size by the valve port opening of control flows control valve 27 simultaneously, the increase of the pressure of piston increases the liquid viscosity resistance between static friction sheet 11 and the movable friction plate 12 gradually, the degree of freedom gradually becomes 1, make the rotating speed of ring gear 3 steadily descend, planet carrier 15 rotating speeds that link to each other with output shaft 9 simultaneously steadily raise, reach the flexible purpose that loads, reduced the impact of load, also reduced impact electrical network.
