Abstract
A water pump comprises a shell, an impeller and a water pump shaft connected with the impeller, wherein one end of the water pump shaft is connected with a power access piece through a speed change mechanism, and the speed change mechanism and the power access piece are located in a box body. The speed change mechanism is a planetary gear type transmission mechanism, one end of the power access piece is fixedly connected with the planetary carrier, the planetary gear is arranged on the planetary carrier, and the sun gear meshed with the planetary gear is detachably connected with the water pump shaft. The invention can be driven by a plurality of power sources, increases the flexibility of power source selection, is convenient to disassemble during maintenance, reduces the purchase cost of users, and has large water pumping amount of the water pump in unit time.
Description
Technical field
The present invention relates to a kind of water pump.
Background technique
At present, the small pump that is used for drawing water in industrial and agricultural production operation or the general family generally drives with motor, the output shaft of motor drives the water pump spindle running, the water pump vane that water pump spindle drives in the water pump cover again rotates, and the water that enters the water pump chamber is pumped out by outlet pipe under the centrifugal action of water pump vane.In use there is following defective in this water pump structure:
(1) water pump and motor are monolithic construction, and dismounting is very inconvenient during maintenance;
(2) form of used power is single, in case meet power failure then can not use;
(3) water pump spindle and motor output shaft are the same axis, and do not have gear, and the rotating speed of water pump is fixed, and the pump water yield of water pump does not have further room for promotion.
Summary of the invention
The problem to be solved in the present invention provides and a kind ofly inserts multiple power source and drive, and dismantles water pump easy to maintenance.
For solving the problems of the technologies described above, the invention provides a kind of water pump, the water pump spindle that this water pump includes housing, impeller and links to each other with impeller, an end of water pump spindle is connected with power by gear and inserts part, and gear and power insert part and are positioned at a casing.
Power inserts part and not only can link to each other with the output shaft of motor, also can be used for connecting petrol engine, diesel engine etc., compares with traditional water pump, water pump and power source are split-type structural, make the power access of water pump more flexible, the power resources mode is more, and dismounting also will make things convenient for manyly during maintenance.In addition, power is separated with the water pump agent structure, water pump can be used the power of other machinery as generator, garden supervisor, Motor Vehicle etc. during use, even all shared power of these machineries such as general gasoline engines drive, just can only need acquire a power when user uses these machineries, thereby reduce purchase cost.
Above-mentioned gear is the planetary gear type driving mechanism, and an end and planet carrier that power inserts part are connected, and planetary pinion is installed on the planet carrier, and central gear that meshes with planetary pinion and water pump spindle are for removably connecting.Adopt this planet gear type driving mechanism to realize speedup, it is little to take up room, and the rotating speed of water pump vane can be greatly improved, and has increased the pump water yield of unit time.
The technique effect that the present invention obtains is: can insert multiple power source and drive, increase the flexibility that power source is selected, convenient disassembly during maintenance has reduced user's purchase cost, and the pump water yield of water pump unit time is big.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Scheme of installation when Fig. 2 is the present invention's usefulness motoring;
Scheme of installation when Fig. 3 is the present invention's usefulness engine-driving;
Among the figure: 1. housing; 2. impeller; 3. water pump spindle; 4. power inserts part; 5. casing; 6. planet carrier; 7. planetary pinion; 8. central gear; 9. bearing; 10. end cap; 11 water pump covers; 12. sealing gasket; 13. fill hose joint; 14. titting water outlet; 15. motor; 16. motor; 17. bent axle; 18. right crankcase cover.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1, the water pump spindle 3 that water pump of the present invention has housing 1, impeller 2 and links to each other with impeller 2, an end of water pump spindle 3 is connected with power by gear and inserts part 4, and gear and power insert part 4 and are positioned at a casing 5.Power inserts part 4 and not only can link to each other with the output shaft of motor, also can be used for connecting petrol engine, diesel engine etc., compares with traditional water pump, water pump and power source are split-type structural, make the power access of water pump more flexible, the power resources mode is more, and dismounting also will make things convenient for manyly during maintenance.In addition, power is separated with the water pump agent structure, water pump can be used the power of other machinery as generator, garden supervisor, Motor Vehicle etc. during use, even all shared power of these machineries such as general gasoline engines drive, just can only need acquire a power when user uses these machineries, thereby reduce purchase cost.
Gear is the planetary gear type driving mechanism, and an end and planet carrier 6 that power inserts part 4 are connected, and planetary pinion 7 is installed on the planet carrier 6, with the central gear 8 of planetary pinion 7 engagements and water pump spindle 3 for removably connecting.Adopt this planet gear type driving mechanism to realize speedup, it is little to take up room, and the rotating speed of water pump vane 2 can be greatly improved, and has increased the pump water yield of unit time.
As can be seen from Figure 1: it is an overall structure with planet carrier 6 that power inserts part 4, and planet carrier 6 is equivalent to the flange plate that power inserts part 4 ends, adopts overall structure, and assembly structure is simplified, and is convenient to install, and intensity is also better.
For spline is connected, central gear 8 drives water pump spindle 3 runnings when rotating between central gear 8 and the water pump spindle 3; It is spline housing that power inserts part 4, and power inserts part 4 and is supported on the end cap 10 of casing 5 by bearing 9.The employing spline connects, and is convenient to realize axially mounting or dismounting apace, also guarantees to carry out simultaneously reliable moment of torsion transmission.
Fig. 2 be the present invention with the assembling schematic representation of motor 15 as power source, the output shaft of motor 15 and power insert part 4 for spline is connected, casing 5 usefulness bolts are connected on the shell of motor 15.
Fig. 3 be the present invention with the assembling schematic representation of motor 16 as power source, the bent axle 17 of motor 16 and power insert part 4 for spline is connected, casing 5 usefulness bolts are connected on the right crankcase cover 18 of motor 16.
The present invention also can insert other power as the case may be and drive, and access way flexibly, conveniently.
