Abstract
The invention provides a coupler capable of achieving stable start. A motor is connected with a left half shaft of a bevel gear planet differential mechanism. A right half shaft is an output shaft. A planet carrier is connected with a friction plate in a hydro-viscous brake. The output torque is controlled by controlling the braking torque of the hydro-viscous brake.
Description
Technical field
The present invention relates to and a kind ofly start controlled connection set, especially a kind of controllable initiating for heave-load device and stepless speed-regulating device.
Background technique
Motor straight connected the dynamic load of speed reducer band, and electric motor starting immediate current is very large, and the moment of output is very large, not only can impact electrical network, and easily cause device damage.Usually motor variable-frequency speed-regulating and hydraulic couplers is adopted to realize smooth starting at present.Big-power transducer is to ambient temperature and turbidity test requirement is high, expensive, constrain its application to heat radiation and requirement of explosion proof.Hydraulic couplers volume is large, have slippage, efficiency lower, poor safety performance.Patent CN201739448U controlled start transmission device adopts the means of machinery to realize the control started, but requiring very high to the braking moment that liquid glues break, friction plate size macrostructure is complicated, and maintenance load large period is long, and power loss is large, the friction plate life-span is short.
Summary of the invention
It is zero that the present invention starts braking moment and output torque instantaneously, can avoid impacting completely; Output torque and braking moment linearly increase, and it is convenient to control; Braking moment is little, can avoid skidding, and structure more simple-to-maintain convenience.
The technological scheme that technical solution problem of the present invention adopts comprises bevel gear planetary differential, liquid glues break.Left half axle is connected with motor, and right axle shaft is as output, and planet carrier and liquid glue break and is connected.Before startup, liquid glues releasing of brake, and output torque is zero.When liquid glue break load gradually time, output torque is about the half of braking moment, can realize smooth starting.
The invention has the beneficial effects as follows, under the effect of lower braking moment, smooth starting can be realized, structure is simple, safe and reliable, control easily, and easily and other speed change gears combinationally use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is schematic diagram of the present invention.1. motors, 2. left half axle, 3. planet wheel, 4. planet carrier in figure, 5. liquid glues break, 6. right axle shaft.
Fig. 2 is another kind of embodiment of the present invention.1. motors, 2. left half axle, 3. planet wheel, 4. planet carrier in figure, 5. liquid glues break, 6. right axle shaft.
Embodiment
In FIG, motor (1) is connected with bevel gear planetary mechanism left half axle (2), right axle shaft (6) is as exporting, liquid glues break (5) when unclamping, planet carrier (4) freely rotates, and right axle shaft (6) output torque is close to zero.Control liquid glues break (5) pressure and can realize progressively loading, then the rotating speed of left half axle (2) progressively reduces, and the moment of left and right semiaxis progressively raises, and when being elevated to enough large, right axle shaft (6) starts to be with dynamic load to start.
Claims (4)
1. start a controllable coupling, glue break by differential mechanism and liquid and form, it is characterized in that: liquid glues break in braking at a high speed, and braking moment is little.
