Abstract
The utility model relates to a high-pressure cleaner, belonging to the technical field of high-pressure cleaning. The high-pressure cleaner solves a problem that the loading and unloading for a current high-pressure cleaner is troublesome and the operation is unstable. The high-pressure cleaner comprises a motor and a high-pressure pump with a pressure regulating assembly, wherein the output shaft of the motor and a crank shaft of the high-pressure pump are outer shafts and are connected by a shaft coupler; flat keys for positioning in radial direction are arranged among the shaft coupler, the output shaft of the motor and the crank shaft; a flange, openings on two ends of which are barrel-shaped, is sleeved outside the shaft coupler; the openings on two ends are respectively fixedly connected with a front end cover of the motor and a pump housing of the high-pressure pump; and the shaft coupler is arranged inside an inner cavity of the flange. The high-pressure cleaner has the advantages that the loading and unloading is convenient and the operation is very stable.
Description
Technical field
The utility model belongs to the jetting machine technical field, refers in particular to a kind of jetting machine.
Background technology
At present, existing its connected mode of cleaning machine is carried out work for the driven by motor high-pressure pump, and its kind of drive has direct-connected and belt transmission; Direct-connected is exactly with high-pressure pump crankshaft designs pore-forming axle; Motor shaft is an outer shaft, and when transmission of power, motor shaft extend in the bent axle endoporus; With the flat key is radial location, utilizes the high-pressure pump flange to be fixedly connected through screw with the motor drive end bearing bracket.Though it is big that this technical scheme has well solved machine volume; Accessory is required the problem of high and fluctuation of service; But simultaneously also exist some problems: mainly be that motor shaft directly is connected with bent axle and carries out transmission of power, grow service time one, is easy to get rusty; Make to be not easy dismounting, also influence the stability of its operation simultaneously.
Summary of the invention
The purpose of the utility model provides a kind of operation jetting machine more stable and easy to loading and unloading.
The purpose of the utility model is achieved in that jetting machine; Comprise motor and the high-pressure pump that has the pressure regulation assembly; It is characterized in that: the output shaft of said motor and the bent axle of high-pressure pump be outer shaft and between connect through shaft coupling; Be equipped with the flat key of ability radial location between the output shaft of shaft coupling and motor, the bent axle; The described shaft coupling outside is arranged with the tubular flange of both ends open, and both ends open is fixedly connected with the drive end bearing bracket of above-mentioned motor and the pump case of high-pressure pump respectively, and shaft coupling is arranged in the flange inner chamber.
Above-mentioned shaft coupling two ends are equipped with holding screw, and holding screw can fasten above-mentioned flat key.
Above-mentioned shaft coupling is provided with elastomer.
The utility model is compared the outstanding advantage of prior art:
1, is connected through shaft coupling between the bent axle of the output shaft of motor and high-pressure pump in the utility model and makes dismounting and install very convenient;
2, the flange both ends open has guaranteed the output shaft and the bent axle coaxial rotation of motor respectively through on the pump case that is bolted to motor drive end bearing bracket and high-pressure pump in the utility model, moves more stable;
3, its flat key can be to motor output shaft and bent axle radial location on shaft coupling in the utility model, and holding screw pushes fixing to flat key, makes power more stable when transmitting;
4, the elastomer on its shaft coupling of the utility model does not play the effect of buffering, and is easy to wear and operation is mild.
