When factory tests, the simulation hydraulic pump load test that each output shaft is lower using the cheap revolving speed of low lattice and the service life is long, this is because very
Real attachment pump is easy to damage, and at high cost;Requirement simultaneously, which cannot generate excessive vibration due to using simulation loading, to be influenced to fly random casket
Work.
Utility model content:
To solve the above-mentioned problems, the utility model provides a kind of multi-functional installation interface that can be realized simulation loading
Switch machine structure realizes simulation hydraulic pump load test using reduction gear box is configured after the mechanism.High with working speed,
It is compact-sized, versatility is high, disassembly is quick, it is reliable, protect casing, effectively improve the characteristics of stability of shafting.
The technical solution adopted in the utility model are as follows: a kind of multi-functional installation interface conversion mechanical structure, including external splines
Axis, quick-release disk, the first bolt, mounting knob, the second bolt, the general output precision of reducing sleeve, high-speed sealing and clamp nut;Institute
Male splined shaft is stated to connect with winged random casket internal spline port;Casing installation seam allowance connect with the quick-release disk, quick-release disk with it is described
The general output precision of reducing sleeve is bolted by first, and the general output precision of reducing sleeve is connected by spline and male splined shaft
It connects, the mounting knob is bolted with the general output precision of reducing sleeve by second, and the flange of shaft coupling passes through clamp nut
It is connect with the general output precision of the reducing sleeve.
The utility model has the beneficial effects that providing a kind of multi-functional installation interface conversion machine that can be realized simulation loading
Tool structure realizes simulation hydraulic pump load test using reduction gear box is configured after the mechanism.It is tight with working speed height, structure
Gather, versatility is high, disassembly quickly, it is reliable, protect casing, effectively improve the characteristics of stability of shafting, be easy to push away on a large scale
Wide and use.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of embodiment one;
Fig. 2 is an application schematic diagram of the embodiment one in aircraft engine accessory power rating casing exerciser.
Specific embodiment:
Embodiment one
Referring to Figures 1 and 2, a kind of multi-functional installation interface conversion mechanical structure, including male splined shaft 1, quick-release disk 2, the
One bolt 3, mounting knob 4, the second bolt 5, the general output precision 6 of reducing sleeve, high-speed sealing 7 and clamp nut 8;The outer flower
Key axis 1 is connect with winged random casket internal spline port;Casing installation seam allowance is connect with the quick-release disk 2, quick-release disk 2 and the switching
It covers general output precision 6 to connect by the first bolt 3, the general output precision 6 of reducing sleeve is connected by spline and male splined shaft 1
It connects, the mounting knob 4 is connect with the general output precision 6 of reducing sleeve by the second bolt 5, and the flange of shaft coupling is by compressing spiral shell
Mother 8 connect with the general output precision 6 of the reducing sleeve.
A kind of multi-functional installation interface conversion mechanical structure (hereinafter referred to as reducing sleeve), reducing sleeve is by mounting knob, switching
General output precision, male splined shaft, quick-release disk, high-speed sealing, clamp nut and corresponding installation is covered to be formed with standard component.Fly attached
Casing respectively exports end interface and is made of internal spline and quick-release ring installation seam allowance, the male splined shaft of reducing sleeve and winged random casket output end
Internal spline is connected, and for transmitting revolving speed and power, flies random casket installation seam allowance and is installed quick-release disk by using conical surface quick-release ring
Be fixed on casing, mounting knob is integrated on the general output precision of reducing sleeve, the general output precision of reducing sleeve by seam allowance with
Bolt is positioned on quick-release disk, and the general output precision output end of reducing sleeve has the mountable ring flange of hickey, ring flange and connection
Axis device is connected, and shaft coupling one end is that the reducing sleeve other end is reduction gear box.Power flow is exported by external splines to reducing sleeve
It on general output precision, then is transmitted on reduction gear box by the shaft coupling of output end, to realize shafting power transfer.
Because the general output precision of reducing sleeve and quick-release disk by seam allowance and are bolted, the general output precision of reducing sleeve is being set
Timing bearing and structure model selection meet the requirement of 0~20000r/min, therefore the spy that the design of reducing sleeve has working speed high
Point.The replaceable various types of ring flanges of the general output precision output end of reducing sleeve, it is different simultaneously for installation dimension on casing
Each output end, only need to change various sizes of quick-release disk and can be realized shafting installation, thus the design have it is compact-sized,
The feature that versatility is high and disassembly is quick.Design has a pair of of main shaft bearing (rolling bearing) in reducing sleeve, disconnected shaft coupling occurs
When the accident for being possible to damage casing internal bearings such as splitting, rolling bearing can damage failure first in reducing sleeve, and transmission chain is made to break
It opens to protect the bearing in casing, while being disposed with shear protective face on male splined shaft, this is cut when torque is more than safety value
Section is broken first, to make male splined shaft fracture failure that can not transmit torque, each spline interface in design protection casing
And gear, bearing, therefore the design of reducing sleeve has the characteristics that reliable, protection casing.The presence of reducing sleeve reduces shaft coupling
Length, thus the characteristics of reducing the critical speed of shaft coupling, the stability of shafting can be effectively improved.With working speed
It is high, compact-sized, versatility is high, disassembly is quick, it is reliable, protect casing, effectively improve the characteristics of stability of shafting.
