Specific embodiment
Further to illustrate that the utility model is the technical means and efficacy reaching predetermined purpose of utility model and being taken,
Below in conjunction with attached drawing and preferred embodiment, to according to the utility model proposes specific embodiment, structure, feature and its effect,
Detailed description is as follows.
Refer to Fig. 2-8, the gap control mechanism of the leafy impeller pump of the utility model first embodiment, including main shaft 1,
Countershaft 2, the main rotor 11 being connected and fixed respectively with main shaft 1, countershaft 2 and secondary rotor 21, cabinet 3, case lid 4, be set in main shaft 1,
Base bearing 12, supplementary bearing 22 outside countershaft 2, main shaft 1 are fixed with main helical gear 13, and countershaft 2 is fixed with to be engaged with main helical gear 13
Secondary helical gear 23, countershaft 2 is threaded in secondary 23 two sides of helical gear for fixing countershaft front nut 24 and countershaft back nut
25, countershaft 2 is arranged with adjusting gasket 26, adjusting gasket between countershaft front nut 24 or countershaft back nut 25 and secondary helical gear 23
26 for adjusting secondary helical gear 23 along 2 axis direction position of countershaft, to adjust the relative position of secondary rotor 21 and main rotor 11, pair
There is the pinion key 27 for transmitting torque, main shaft 1 is threadedly coupled in main 13 two sides of helical gear between axis 2 and secondary helical gear 23
There are main shaft front nut 14 and main shaft back nut 15, there is the master gear key for transmitting torque between main shaft 1 and main helical gear 13
16, there is the main rotor key 17 for transmitting torque between main rotor 11 and main shaft 1, have between secondary rotor 21 and countershaft 2 and use
In the secondary rotor key 28 of transmitting torque, base bearing 12, supplementary bearing 22 are contained in cabinet 3, and case lid 4 is located at cabinet 3 towards main tooth
The side of wheel and pinion, case lid 4 are barrel-like structure, countershaft front nut 24, countershaft back nut 25, secondary helical gear 23, spacer
Piece 26 is contained in case lid 4, and case lid 4 is removably connected and fixed with cabinet 3.
When adjustment, the main helical gear 13 of main shaft 1 is first fixed outside cabinet 3, prevents gear from moving axially, recycle dedicated
Tool moves axially secondary helical gear 23, drives adjustment front end main rotor 11 and secondary 21 gap of rotor variation, after adjusting gap,
