Abstract
The utility model discloses a speed reducing mechanism for a water pump. An air suction and exhaust device for the conventional strong self-suction series pump has low working efficiency and short service life. The speed reducing mechanism consists of a pump shaft (1), wherein a sliding outer gear (2) is arranged on the pump shaft, and is connected with a shifting fork (6) through a slip ring and a pin shaft (5); the shifting fork is connected with a rotating shaft (7); the rotating shaft is connected with a poke rod (8); a driven inner gear (9) meshed with the sliding outer gear is arranged on a shaft (10) which is concentric with the pump shaft; a speed reducing device is arranged on the shaft; and a crank connecting rod is arranged at the output end of the speed reducing device. The product is applied to an assorted device of the strong self-suction series pump.
Description
Technical field:
the utility model relates to a kind of reducing gear, is specifically related to the special-purpose reducing gear of a kind of water pump.
Background technique:
are present, and known pump drive form all is the driven by motor pump shaft, realize the transmission of direct connection geometric ratio, and the suction-exhaust device of eccentric power taking obtains the geometric ratio transmission too from the pump shaft.But when motor speed is higher, the working efficiency of suction-exhaust device and working life will significantly reduce, and these all are unfavorable factors, therefore under the situation that does not change the pump shaft rated speed, must make suction-exhaust device obtain under the normal working than the slow-speed of revolution.
Summary of the invention:
The purpose of
the utility model provides the special-purpose reducing gear of a kind of water pump; Required rated speed when this mechanism can not only guarantee pump working; And can satisfy suction-exhaust device obtain under the normal working than the slow-speed of revolution; Can also realize simultaneously suction-exhaust device from, close action, save air horsepower, improve its working life.
Above-mentioned purpose realizes through following technological scheme:
a kind of water pump is used reducing gear; Its composition comprises: pump shaft; The slip external gear is installed on the described pump shaft, and described slip external gear is connected shift fork through slip ring with bearing pin, and the rotatingshaft of described shift fork connects turning lever; With the passive internal gear of described slip external gear engagement be installed in the concentric axle of pump shaft on, the output terminal of the planetary reduction gear that described axle the connects connecting rod that cranks.
described water pump is used reducing gear, spiral-lock left side slip ring and right slip ring in the chute of described slip external gear, and described left slip ring is connected shift fork through bearing pin respectively with right slip ring.
described water pump is used reducing gear; Described speed reducer comprises sun gear; Described sun gear and planetary pinion engagement; Described planetary pinion and the engagement of internal tooth eccentric wheel, on described axle, described internal tooth eccentric wheel connects described crank to described internal tooth eccentric wheel through two Bearing Installation.
described water pump is used reducing gear, and described axle connects supporting frame through two bearings, comprises air relief cock and handhole cover on the described supporting frame.
described water pump is used reducing gear, comprises pinning, position-arresting disk and sliding pin on the described rotatingshaft.
Beneficial effect:
required rated speed when 1. the utility model can not only guarantee pump working; And can satisfy suction-exhaust device obtain under the normal working than the slow-speed of revolution; Can also realize simultaneously the clutch action of suction-exhaust device, save air horsepower, improve working life.
2. the inner driving mechanism of the utility model speed reducer all are installed on the supporting frame, convenient for assembly, maintenance, dismounting.
Description of drawings:
accompanying drawing 1 is the structural representation of the utility model.
accompanying drawing 2 is A-A sectional drawings of accompanying drawing 1.
Embodiment:
Embodiment 1:
water pump is used reducing gear, and its composition comprises: pump shaft 1, through flat key 25 slip external gear 2 is installed on the described pump shaft; Spiral-lock left side slip ring 3 and right slip ring 4 in the chute of described slip external gear, described left slip ring is connected shift fork 6 through bearing pin 5 respectively with right slip ring, and described shift fork connects rotatingshaft 7; Described rotatingshaft connects turning lever 8, described slip external gear and 9 engagements of passive internal gear, described passive internal gear be installed in pump shaft concentric spools 10 on; Described axle is gone up with flat key sun gear 11 is installed; Described sun gear and planetary pinion 12 engagements, described planetary pinion and 13 engagements of internal tooth eccentric wheel, described internal tooth eccentric wheel is installed on the described axle through two bearing A14; Eccentric assembling crank 15 on the described internal tooth eccentric wheel, described crank connects connecting rod 16.
described water pump is used reducing gear, and described axle connects supporting frame 18 through two bearing B17, comprises air relief cock 19, oily window 20 and handhole cover 21 on the described supporting frame.
described water pump is used reducing gear, comprises pinning 22, position-arresting disk 23 and sliding pin 24 on the described rotatingshaft.
both can drive axle and synchronously rotate after slip external gear and the engagement of passive internal gear; Power reaches the internal tooth eccentric wheel through sun gear, planetary pinion; Thereby the power after obtaining to slow down reaches crank; The crank upper end connects connecting rod, by connecting rod power is passed to suction-exhaust device, realizes suction and discharge work.When the manipulation turning lever, and under the synergy of slide block, pinning, position-arresting disk, sliding pin etc., realize forward and reverse rotation of rotatingshaft, and then stir sliding pin, drive the slip external gear and slide vertically, thereby realize leaving, closing action through the shift fork of end band chute.
