Abstract
The utility model discloses a power system of a grab loader. The power system of the grab loader comprises a motor, a spacer sleeve, a bell housing, a coupler, a main pump and a triple-gear pump. The bell housing is used for being connected with the motor and the axial plunger pump and fixing the motor and the axial plunger pump. The quincunx elastic coupler transmits the torque of a motor shaft to an input shaft of the axial plunger pump. An output hole of the axial plunger variable pump and an input shaft of the triple-gear pump are connected through a spline so as to transmit power. The main pump is the axial plunger variable pump. The power system of the grab loader has the advantages that four hydraulic pumps can be driven by one motor to work, all the hydraulic pumps are identical in rotation speed, the span is large, the transmitted torque is high, the structure is compact, work is reliable, and the number of the motor and the installation space of the motor are reduced.
Description
Technical field
The utility model relates to a kind of dynamical system, and specifically one is taken off rock mechanomotive force system.
Background technology
The existing rock mechanomotive force system of taking off has following shortcoming: 1, taking off rock mechanomotive force system still adopts positive coupling to connect, in the time starting and brake, motor and pump are all produced to huge impact, seriously reduce the application life 2 of dynamical system, because the hydraulic pump that this dynamical system is required is more, the overwhelming majority takes off rock mechanomotive force system and all adopts two or more motors to drive hydraulic pump, will increase like this motor and ancillary service (as vacuum electromagnetic starter, cable etc.) number, except increasing extra cost, the shared space of whole system also can increase, be unfavorable for using in the narrow and small environment such as tunnel or tunnel.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides one to take off rock mechanomotive force system, can work together by four hydraulic pumps of a driven by motor, and all hydraulic pump all has same rotational speed, span is large, and transmitting torque is high, compact conformation, reliable operation, reduces number of motors and installing space.
To achieve these goals, the technical solution adopted in the utility model is: one is taken off rock mechanomotive force system, comprise motor, interstage sleeve, bell-jar, shaft coupling, main pump and combination triple gear pump, described bell-jar is used for connecting motor and axial plunger pump, fixes the relative position of the two; Quincunx elastic coupler passes to the moment of torsion of motor shaft the power shaft of axial plunger pump; The delivery outlet of shaft orientation plunger variable pump carrys out transferring power with the power shaft of combination triple gear pump by spline joint again, and described main pump is shaft orientation plunger variable pump.
Described shaft coupling is Quincunx elastic coupler.
Compared with prior art, the utility model has been realized the function that only uses a motor just to drive four hydraulic pumps to work together, and all hydraulic pump all has same rotational speed, span is large, and transmitting torque is high, compact conformation, reliable operation, not only reduce number of motors and installing space, and reduced cost of production and energy loss, facilitated lectotype selection and centralized Control.When use, only motor base need be fixed in place, whole dynamical system can normally be worked, and without increasing again hydraulic pump mount, thereby avoided crossing the axial dipole field that constraint may cause, transferring power more steadily, reliably, has improved safety greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is dynamical system figure of the present utility model.
In figure: 1, motor, 2, interstage sleeve, 3, bell-jar, 4, shaft coupling, 5, shaft orientation plunger variable pump, 6, combination triple gear pump.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, one is taken off rock mechanomotive force system, comprises motor 1, interstage sleeve 2, bell-jar 3, shaft coupling 4, main pump and combination triple gear pump 6, and described main pump is shaft orientation plunger variable pump 5, described bell-jar 3, for connecting motor 1 and axial plunger pump 5, is fixed the relative position of the two; Quincunx elastic coupler 4 passes to the moment of torsion of motor shaft the power shaft of axial plunger pump 5; The delivery outlet of shaft orientation plunger variable pump 5 carrys out transferring power with the power shaft of combination triple gear pump 6 by spline joint again.
Fig. 2 is dynamical system figure of the present utility model, combination triple gear pump 6 is respectively the first gear pump, the second gear pump and Three gear pump, motor 1 drives the first gear pump, the second gear pump and Three gear pump and main pump, main pump connecting excavator structure and walking mechanism, the first gear pump connects conveying motor, lifts groove oil cylinder and push pedal oil cylinder, the second gear pump connects pilot control and running motor speed governing, and Three gear pump connects oil return cooler.Main pump for excavate and walking mechanism power is provided; The first gear pump is supplied with conveying system, comprises conveying motor, lifts groove oil cylinder and push pedal oil cylinder; The second gear pump is responsible for realizing the function such as pilot control, running motor speed governing, and Three gear pump drives oil return cooler normally to work, and four hydraulic pumps work alone, and realizes mutually function separately, but can centralized Control, is convenient to start and stop.
Compared with prior art, the utility model has been realized the function that only uses a motor just to drive four hydraulic pumps to work together, and all hydraulic pump all has same rotational speed, span is large, and transmitting torque is high, compact conformation, reliable operation, not only reduce number of motors and installing space, and reduced cost of production and energy loss, facilitated lectotype selection and centralized Control.When use, only motor base need be fixed in place, whole dynamical system can normally be worked, and without increasing again hydraulic pump mount, thereby avoided crossing the axial dipole field that constraint may cause, transferring power more steadily, reliably, has improved safety greatly.
