Abstract
The utility model discloses a kind of Cam type double-rotor pump that can prevent from overloading displacement, because the gear on traditional main shaft and countershaft is fixed by set of books, but the situation that this fixed form is easy to produce overload displacement occurs, influence the work of Cam type double-rotor pump, make advantageous embodiment, the utility model is simple in construction, originally double flat key fixed gear will be changed to by way of set of books fixed gear, efficiently solve the generation of overload misalignment, the Cam type double-rotor pump body top for overloading displacement can be wherein prevented to be fixedly installed suspension ring by bolt and nut and facilitate mobile transport of the present utility model.
Description
Technical field
Pump industry field is the utility model is related to, specially a kind of Cam type double-rotor pump that can prevent from overloading displacement.
Background technology
The Cam type double-rotor pump that can prevent from overloading displacement uses two rotors being synchronized with the movement, and rotor is external by a pair
Formula synchronous gear box is driven, and rotor synchronizes opposite direction rotation under the drive of power transmission shaft, higher so as to constitute
Vacuum and discharge pressure, are particularly suitable for the conveying of pharmaceutical grade medium and corrosivity high viscosity medium.Wherein main shaft and countershaft rotation
Turn in opposite direction, be arranged with gear outside main shaft and countershaft, by gear drive, the gear on traditional main shaft and countershaft is all logical
Set of books fixation is crossed, but the situation that this fixed form is easy to produce overload displacement occurs, and influences Cam type double-rotor pump
Work.
Utility model content
The purpose of this utility model is to provide a kind of Cam type double-rotor pump that can prevent from overloading displacement, with solution
State the problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of cam that can prevent from overloading displacement
Formula birotor pump, including Cam type double-rotor pump main body, the Cam type double-rotor pump main body include main shaft on its interior
With countershaft, positioned at the pump cover of cam-type birotor body side, it is characterised in that：The main shaft and countershaft are equal away from pump cover side
Flat key is provided with, the main shaft and countershaft are fixed with gear by flat key.
Preferably, the pump cover is fixedly connected by bolt and nut with Cam type double-rotor pump main body.
Preferably, the Cam type double-rotor pump body top is fixedly installed suspension ring by bolt and nut.
Preferably, the flat key on the main shaft and countershaft is provided with two, and is symmetrical arranged.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, will pass through account originally
The mode of set fixed gear is changed to double flat key fixed gear, the generation of overload misalignment is efficiently solved, wherein can prevent
The Cam type double-rotor pump body top of overload displacement is fixedly installed suspension ring by bolt and nut and facilitates shifting of the present utility model
Dynamic transport.
