Abstract
The utility model relates to an engine part specifically is linear chain type air compressor driven shaft sleeve, including the axle sleeve body, axle sleeve body one end has the cross keyway for with air compressor cooperation, the axle sleeve body other end has the bell mouth, and it has the parallel key groove to open in the bell mouth, be used for with the hookup of injection pump tapering spindle, threaded hole is left to radials in addition on the external lateral wall of axle sleeve on the radials, be used for with injection pump gear couplings. With this directly link type air compressor driven shaft sleeve and diesel engine injection pump gear couplings, the diesel engine crankshaft toothed wheel passes through the rotation of idler gear drive injection pump gear to the work of drive air compressor, effective, with low costs, the use in batches of easily producing, be convenient for of simple structure.
Description
Technical field
This utility model relates to a kind of engine part, is specially straight chain type air compressor propeller shaft sleeve.
Background technology
The matched diesel engine of farm machinery is required coupling air compressor more, for auxiliary brake or sprinkling irrigation power, conventional driving adopts belt drives more, and efficiency is low and fault rate is high, is badly in need of a kind of direct-coupled air compressor driving device and is solved.
Utility model content
For the problems referred to above, this utility model provides the one direct-coupled air compressor propeller shaft sleeve that coupling direct-connected " cross key " air compressor uses.Transmission efficiency can be effectively improved, reduce fault rate.
Concrete technical scheme is:
Direct linkage type air compressor propeller shaft sleeve, including sleeve body, there is cross keyway sleeve body one end, for coordinating with air compressor, the sleeve body other end has bellmouth, has flat key groove in bellmouth, for coupling with injection pump diminished shaft, sleeve body lateral wall also has disc, disc has screwed hole, for coupling with fuel injection pump gear.
On original Gear Cavity Cover of Diesel Engine, design air compressor interface installs air compressor, couple with diesel engine fuel injecting pump gear with this direct linkage type air compressor propeller shaft sleeve, diesel engine crankshaft gear drives the rotation of fuel injection pump gear by idle gear, thus driving air compressor to work.
This utility model provide direct linkage type air compressor propeller shaft sleeve, simple in construction is effective, cost is low, easy production, be easy to batch use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is direct linkage type air compressor propeller shaft sleeve fundamental diagram of the present utility model.
Detailed description of the invention
Accompanying drawings detailed description of the invention of the present utility model, as it is shown in figure 1, direct linkage type air compressor propeller shaft sleeve, including sleeve body, there is cross keyway 1 sleeve body one end, for coordinating with air compressor, the sleeve body other end has bellmouth 3, has flat key groove 4 in bellmouth 3, for coupling with injection pump diminished shaft, sleeve body lateral wall also has disc 2, disc 2 has screwed hole, for coupling with fuel injection pump gear.
Specific works mode is: crankshaft of diesel engine rotarily drives crankshaft toothed wheel and rotates, and crankshaft toothed wheel drives fuel injection pump gear by idle gear, and fuel injection pump gear drives air compressor and injection pump work by direct linkage type air compressor propeller shaft sleeve.
It is specifically shown in Fig. 2.Air compressor 10 is positioned by seam and bolt fixed mode is arranged on gear chamber cover 20, its cross key coordinates with the cross keyway 1 of direct linkage type air compressor propeller shaft sleeve 40, direct linkage type air compressor propeller shaft sleeve 40 is coupled with fuel injection pump gear 30 by bolt 60, and direct linkage type air compressor propeller shaft sleeve 40 other end is coupled by bellmouth 3 peace keyway 4 mode with injection pump 70.Idle gear 50 choosing dress drives fuel injection pump gear 30 to rotate, and is driven air compressor and injection pump work by direct linkage type air compressor propeller shaft sleeve 40.
