Abstract
The invention relates to a feathering impeller pump type brake used for controlling a separation strip to lift or depress to realize precision brake. The operating principle of the feathering impeller pump type brake is that the separation strip is like a gate, the separation strip controls the size of hydraulic oil which flows in a feathering impeller pump so as to generate the resisting force of corresponding strength; and the feathering impeller pump type brake has accurate brake control, the friction is small in an idle running, the feathering impeller pump type brake is sealed and durable, as the friction force is not needed to brake. Therefore, a brake block is not needed, the brake block does not need to change, the braking mill dust is not generated, and the feathering impeller pump type arrester is environment-friendly and is a revolution of the brake.
Description
The present invention is a kind of mentioning or depress and just can realize the commentaries on classics blade wheel pump formula break accurately braked with the control dividing strip.
Its working principle is: one does not have the commentaries on classics blade wheel pump imported and exported, and dividing strip is just as a gate, the hydraulic oil size that revolution is flowed in the control pump and produce the resistance of corresponding size.It has braking control accurately, and it is little, hermetically sealed, durable to rub during idle running, because be not to brake with frictional force, use from blocked force and brakes, and therefore without brake block, need not change brake block, does not produce the brake dust, environmental protection.It is the revolution of break.
At present, the product category of break is a lot of on market, dish formula, ventilation dish, drum-type.But all be to brake with frictional force, the present invention leans on the pump formula break of braking from blocked force, and it has sealing, and is durable, and braking is accurate, and idle running has oil lubrication, and the advantage of waiting indefinitely can not dug in ability fixed main shaft position, and the market competitiveness is strong.
Be to combine Figure of description to come working principle of the present invention is further explained below.
Fig. 1 is a main accompanying drawing of the present invention.
Fig. 2 removes to cover view on one side
Fig. 3 is criss-crossing blade and rotor main shaft broken away view
Fig. 4 is a dividing strip. fan-shaped pumping cylinder is carefully schemed
Among the figure, 1. packing holder 2. bearing supports 3. braking dividing strips 4. pump housing limits lid 5. is separated draw runner positioning seat 6. is changeed the filling blade 10. fan-shaped pumping cylinders on paddle wheel main shaft 7. cam bits 8. blades 9. main shafts
When the rotor main shaft of oar rotating vane wheel pump formula break with a car in wheel when being installed together, the wheel that rotates of advancing drives the blade during through cam bit that changes blade wheels main shaft, the edge is pushed up by cam bit; Can turn 90 degrees with cam bit bent face cunning; In this process, the blade of opposite end has also rotated 90 degree simultaneously, and the blade face is vertical with the fan-shaped pumping cylinder of two side covers; Form piston, begin to do compression work.Wherein dividing strip is just as a gate, mentions or depresses the capacity of reflux of controlling compressed hydraulic oil, and the resistance of formation feeds back to through blade and obtains torsion on the main shaft.Because change in volume was very small when hydraulic oil was compressed, so the gate effect of dividing strip can realize in precisely quick control.When being pressed onto the end to dividing strip, dividing strip only lets blade follow the filling blade on the main shaft to pass through, compressed hydraulic oil can not reflux through dividing strip, the blade compression not feed back to main shaft and also do not rotate.When a bit, some can reflux compressed hydraulic oil from the dividing strip space as mentioning dividing strip, controls dividing strip exactly and obtains corresponding resistive torque with the hydraulic oil capacity of reflux size that the spacing of main shaft changes through dividing strip.When mentioning dividing strip fully; Just there is not dividing strip to block compressed hydraulic oil; So compressed hydraulic oil is made circular movement in the pump housing; At this moment the rotor main shaft idle running of changeing blade wheel pump formula break does not produce resistive torque, and except producing some mechanical friction resistances, what resistance other have not had.
Beneficial effect following points of the present invention:
1, good airproof performance, braking is not influenced by outside environment.
2, control precisely can realize a plurality of identical brake drag controls simultaneously.
3, brake without frictional force, have the oil lubrication parts durable in use.
4, can be directly installed on wheel on the rotor main shaft that changes blade wheel pump formula break, the effect of location can be arranged.
5, change blade wheel pump formula break and brake, so can not dig dead braking to block hydraulic oil.
6, the heating of braking generation can well transmit out through hydraulic oil, and the long-time braking of lower long slope can not cause brake failure yet.
Claims (2)
1. one does not have the commentaries on classics blade wheel pump imported and exported, and dividing strip is just as a gate, the hydraulic oil size that revolution is flowed in the control pump and produce the commentaries on classics blade wheel pump formula break of the resistance of corresponding size.
2. rotary pump according to claim 1 is characterized in that: brake without frictional force but block the pump formula break that the hydraulic oil revolution flow in the control sealing pump housing is realized braking with a simple dividing strip for one.
