Abstract
This utility model is related to a kind of dual pathways without slippage fluid-flywheel clutch gear drive, which includes coupling device, gear pair and controllable clutch, coupling turbine side arranges a pair and the preposition gear pair identical gear pair of coupling device, and in two pairs of identical gear pair input shaft middle setting controllable clutch.This device is when with high speed frequency control device configuration, in frequency control operating mode, which is run in speed increasing gear box function, no slippage as common step-up gear, once converter breaks down, motor switches to power frequency, and device switches to coupling device gear and becomes coupling device speed governing operation.Relative to common hydraulic coupler transmission device, this actuating device is without hydraulic-slip loss.
Description
Technical field
The present invention relates to a kind of actuating device, more particularly to a kind of dual pathways is without slippage fluid-flywheel clutch loading drive gear
Put, can be used for the heavy duties such as thermoelectricity, nuclear power, petrochemical industry, high speed, the soft start of low-speed device, stepless speed regulation to reach energy-conservation purpose.
Background technology
At present, domestic power station, the multiplex fluid-flywheel clutch speed change of petrochemical industry high-speed overload equipment speed control device, such as station boiler are given
Water pump, blower fan etc.；With country or even international community's carrying for " energy-saving and emission-reduction ", the consciousness of " carbon emission amount " and attention rate
Height, some short slabs of fluid-flywheel clutch gradually cause the concern of people.Because its speed governing conversion efficiency declines as rotating speed is reduced,
Overall efficiency is relatively low.In addition, fluid-flywheel clutch belongs to slip loss type arrangements for speed regulation, during speed governing, slip work(
Rate is lost in oil in the form of heat energy, adds additional energy consumption.Especially in underload such as speed of feedwater in gear ratio 60%
When energy loss just reach 42% or so.And the mode of social need electricity determines that generating set absolutely not may be maintained all the time
90%ECR（Economical operating condition）Above load operation.For this problem, to motor Frequency Conversion Modification, fluid-flywheel clutch
The scheme of the only transformation of transmitting torque is arisen at the historic moment, wherein changing core component pump impeller, the turbine of transmitting torque and adjustment rotating speed
For shaft coupling, coupling device makes gear-box functional requirement into and also gradually steps up, but as feed pump mostly is monoblock, once frequency conversion
Device breaks down, unit cannot speed change cause unit have to shut down, so some users employ in Frequency Conversion Modification and still protect
Coupling device speed-regulating function is held, and coupling device scoop tube keeps 100% in frequency control, makes and increases with simple gear-box
Fast function, due to the slippage for also having 3% during coupling device maximum (top) speed, though once in this way allow occurs in converter
During failure, motor is convertible into power frequency, and unit can reply coupling device speed governing, but have lost at least 3% efficiency, for big work(
The loss of rate unit is very considerable！If the loss of 5000kw units is exactly 150kw, that is, 150 degree of electricity/hours are lost, by annual 8000
It is electric that hour calculates 1,200,000 degree of annual waste.
The content of the invention
For above-mentioned situation, the invention provides a kind of have two kinds of functions of coupling device speed governing and gear-box simultaneously, and can
The dual pathways that can be changed at any time as needed in operation is without slippage fluid-flywheel clutch gear drive.
Technical scheme is as follows：
Actuating device, including coupling device, gear pair and controllable clutch, before a pair of coupling turbine side setting and coupling device
Gear pair identical gear pair is put, and in two pairs of identical gear pair input shaft middle setting controllable clutch.
Described gear pair is speed increasing gear train and speed reducing gear pair.
Advantages of the present invention effect is as follows：
When with high speed frequency control device configuration, in frequency control operating mode, which transports this device in speed increasing gear box function
OK, no slippage as common step-up gear, once converter breaks down, motor switches to power frequency, device switching
Become coupling device speed governing operation into coupling device gear.
Relative to common hydraulic coupler transmission device, this actuating device is because without hydraulic-slip loss so as to which efficiency improves 3%,
Such as supporting high-power, the high rotating speed fluid power of 600MW supercritical, 50% capacity boilers of ultra supercritical coal-fired unit feedwater pump assembly
Coupler transmission device power is 8000-9000kW, if using the coupler transmission device without slippage, such equipment is every
Hour can be economized on electricity 240-270 degree, ten thousand degree of 192-216 of year economize on electricity.
For important speed control device, such as station boiler feed pump, configuration can be combined with frequency control, when frequency control
The gear box function of use device, improves energy-saving effect；When converter plant failure uses actuating device coupling device speed-regulating function, make
With coupling device speed-regulating function itself as standby, the security reliability of equipment is improve.
In the rotation machinery with low-speed heave-load with large rotating inertia such as：When ball mill, disintegrating machine, coal conveyor etc. are configured,
Fluid-flywheel clutch functional realiey unit soft start can be used, gear-box work(is converted into when unit reaches declared working condition so as to subtract
Few hydraulic-slip loss realizes that to reach energy-conservation purpose, in addition soft start can reduce electric motor starting electric current, reduces the type selecting cost of motor,
Increase the service life of motor.
In addition, in gear box function, as power and energy is, using special controllable clutch structure, to embrace in working machine
Wait indefinitely accident conditions, clutch is skidded due to moment of torsion excess overload, so as to protect motor.
