Abstract
The utility model discloses a counter regulation type liquid viscosity speed controller, which is mainly used for regulating speed and saving energy for the machinery classes such as blowers and water pumps. The utility model comprises a drive section, a driven section, a pressing mechanism and a separation mechanism, wherein, a pressing spring is installed on the circumference of a piston; an oil cylinder cover is arranged between the piston and a bearing which is arranged on a driven shaft head, and a guide pin is also arranged between the piston and a driven hub. The difference between the utility model and other liquid viscosity speed controllers lies in that the usual operation mode of the utility model is directly driven by that the spring presses a clutch, thus, the lubricating oil pump and the oil control pump of the system can be used only when the speed is controlled. The utility model is particularly suitable for the blower and the water pump which do not need controlling speed frequently; energy saving effect and operational reliability are enhanced; the service life of the liquid viscosity speed controllers and oil systems are prolonged.
Description
The utility model relates to a kind of stepless speed regulation energy saving device, can be used for the speed governing of blower fan, water pump.
Along with the in short supply and rise in price of the energy, energy-conservation is problem anxious to be solved.Blower fan, water pump electricity consumption account for 1/3 of total power consumption, are one of universal machines of power consumption proportion maximum.Therefore the power saving that solves blower fan and water pump is extremely important.Traditional throttling regulative mode, blower fan and water pump to variable parameter operation exist huge waste of energy.In existing blower fan and pump speed control technology, hydro-viscous speed governing clutch is the speed-regulating actuator made from the design of liquid viscosity and oil-shear action principle.One group of master, driven friction are installed respectively on the input and output axle, are full of working oil between friction plate, can control the oil slick thickness that places between master, driven friction by control gear.When oil slick thickness not simultaneously, main, driven friction carry-over moment varies in size, thereby realizes transmitting torque and output speed are carried out stepless speed regulation.This arrangements for speed regulation have simple in structure, and function admirable is reliable, easy to maintenance, advantages such as obvious energy conservation, but the lubricating pump of this device and control oil pump still do not work when blower fan and water pump do not need the direct transmission condition of speed governing, thus wasted certain electric energy.Beijing Institute of Technology once disclosed a kind of " hydro viscous variable speed drive " patented technology, patent No. ZL:92244593.1 in 92 years.This patent is mainly disclosed to be positive mode hydro-viscous speed governing clutch.
The purpose of this utility model provides and a kind ofly is applicable to that blower fan and water pump civil time are the anti-mode hydro-viscous speed governing clutches of direct transmission condition.
The purpose of this utility model is realized by following proposal: the anti-mode hydro-viscous speed governing clutch that is made of active part, passive part, hold-down mechanism and separating mechanism.Hold-down mechanism is made of holddown spring, and separating mechanism is to be made of oil cylinder cover and piston.Between the circumference of piston and passive hub, holddown spring is housed, between the bearing of piston and passive spindle nose, oil cylinder cover is housed, between piston and passive hub, guide finger is housed also.
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is the structural drawing of speed regulator
The driving shaft 1 of anti-mode hydro-viscous speed governing clutch links to each other with motor power, active friction plate 2 links to each other with driving shaft by spline, driven friction 3 links to each other with passive hub 9 by spline, and passive hub links to each other with driven axle 4 by flat key, and driven axle links to each other with blower fan or water pump.Support mutually by bearing between driving shaft and the driven axle, form an integral body, be bearing on the housing by two bearings again, simple in structure like this, compact.The substrate hold-down function of clutch be by radially equally distributed several holddown springs 5 realize main, passive between 1: 1 transmission (being direct transmission, the operating mode when not needing speed governing this moment).The separation speed governing of clutch is to overcome the holddown spring active force by regulating the control-oil pressure that the driven axle oilhole enters piston 8 oil cylinders, realizes its speed governing purpose, is connected with oil cylinder cover 6 on the pillow block of piston.Clutch is by the lubricating pump fuel feeding, and the filler opening of lubricant oil process driving shaft is to friction plate, and through the sheet gap of friction plate and the oil groove on the friction plate, the oilhole by on the passive shell 9 is thrown in the housing, and bearing is lubricated, and the torrid zone that the sliding merit of rubbing produces is walked.The effect of guide finger 7 is steady when making piston axial displacement, accurate.
The working state commonly used of anti-mode hydro-viscous speed governing clutch is for compressing the direct transmission condition in conjunction with clutch by holddown spring, lubricating pump and control oil pump are not worked this moment, have saved the electric energy of oil supply system motor.When needing speed governing, open lubricating oil pump motor and control Oil pump electrical machinery, reach by the pressure of regulating control oil and regulate gap between the clutch friction plate sheet, thereby reach the speed governing purpose.This device is applicable to and often is in the blower fan and the water pump of operating at full capacity; Good energy-conserving effect, simple in structure, reliable operation, life-span are long.
