Worm gear case breakaway torque test system.
The solution of the present invention is such：
A kind of worm gear case breakaway torque test system, includes the mounting bracket of support worm gear case, the one of the output shaft arm of force of worm gear case
End connection, the other end of the arm of force has arcwall face, contacted at arcwall face with push rod, the contact position of the push rod and the arm of force
To be round so that the arm of force and push rod contact position formation linear contact lay；The push rod is fixed on the mobile terminal of jack, by jack
The band trend arm of force applies active force.
More specifically technical scheme also includes：The described arm of force is fixed with the level meter for observing arm of force horizontality.
Further：The mobile terminal of the jack is fixed with pull pressure sensor, and the pull pressure sensor support is pushed away
Bar, the active force of the arm of force is put on to measure.
Further：The mounting bracket includes base, installing plate, and installing plate and base are bolted；It is described to install
Plate is bolted worm gear case.
Further：The jack is integrally fixed at the height adjustment seat for adjusting height.
Further：The mobile terminal of the jack is fixed with transition sleeve, fixed set upper side connection pull pressure sensor.
Further：The push rod is cylinder so that the arm of force and push rod contact position formation linear contact lay.
Further：Worm screw is installed on the worm gear pole axle of worm gear case and rotates instruction device, the worm screw, which rotates, to be indicated
Device follows worm shaft.
It is an advantage of the invention that in breakaway torque test system, it is not necessary to counterweight is used, using jack, operation side
Just, the test being particularly suitable for use in for high pulling torque；And the rotation of the arm of force does not influence on the torque arm length of practical function, and data are more
Plus it is accurate；The worm gear case breakaway torque test system manufacturing cost of the present invention, it is easy to use, and result is accurate, overcomes mesh
The defect that the breakaway torque of preceding land leveller worm gear case is tested in complete machine.
Brief description of the drawings
Fig. 1 is the structural representation of the worm gear case breakaway torque test system of the present invention.
Fig. 2 is the worm gear case mounting bracket schematic diagram of the worm gear case breakaway torque test system of the present invention.
Fig. 3 is the worm gear case breakaway torque test system part-structure schematic diagram of the present invention.
Reference is in figure：Mounting bracket 1, worm gear case 2, worm screw rotate instruction device 3, the arm of force 4, level meter 5, push rod 6,
Pull pressure sensor 7, transition sleeve 8, jack 9, height adjustment seat 10, base 11, installing plate 12.
Embodiment
The present invention is as shown in figure 1, worm gear case mounting bracket 1 is fixed on the ground, and is used to install worm gear case 2, mounting bracket 1
Including base 11, installing plate 12, installing plate 12 and base 11 are bolted；The installing plate 12 is bolted worm gear
Case 2, can change different installing plates, to adapt to different worm gear cases.Worm screw rotates instruction device 3 and is arranged on worm shaft,
Worm shaft can be followed, for adjusting and observing worm screw rotation.The arm of force 4 is used to transmit moment of torsion, and one end is defeated with worm gear case 2
Shaft is connected, and one end is contacted with push rod 6, and the power that push rod 6 is transmitted is acted on worm-gear case output shaft, can change different power
Arm, is able to coordinate the size of different worm-gear case output shafts.Level meter 5 is placed on the arm of force 4, for observing the horizontal of the arm of force 4
State.The one end of push rod 6 is connected through a screw thread with pull pressure sensor 7, and the other end is contacted with the arm of force 4 by arcwall face.Pressure is passed
Sensor 7 is used to record pressure, includes the data conditioning acquisition system of itself.The one end of transition sleeve 8 passes through spiral shell with pull pressure sensor 7
Line is connected, and the other end is contacted with jack 9, the power for transmitting jack generation.Jack 9 is fixed on height adjustment seat 10
On, for producing power.Height adjustment seat 10 is fixed on the ground, can adjust different height, to adapt to different worm gear cases
And pull pressure sensor is to the demand of different height.Worm gear case mounting bracket 1 is fixed on the ground, worm gear case 2 is fixed on snail
On roller box mounting bracket, worm screw is installed and rotates instruction device 3 and the arm of force 4, the observation level of instruction device 3 is rotated by adjusting worm screw
Instrument, makes the arm of force be in horizontal level.Height adjustment seat 10 is fixed on the ground below the contact graduation mark of the arm of force, and in height
Jack 9, transition sleeve 8, pull pressure sensor 7, push rod 6 are installed successively in degree adjustment seat 10.Move integrally regulation jack 9,
Transition sleeve 8, pull pressure sensor 7, push rod 6, make push rod 6, in the position contact of contact graduation mark, jack 9 be consolidated with the arm of force 4
It is scheduled in height adjustment seat 10.Height adjustment seat is adjusted to suitable height, pull pressure sensor 7 is reset, you can surveyed
Examination.By jack applying power, the arm of force 4 up rotates or has rotation trend, worm-gear case output shaft is born torque.Observation is simultaneously
The output data of pressure meter is recorded, when worm gear case skids moment, the output data of pressure can decline suddenly, and pressure meter is defeated
The maximum pressure gone out is multiplied by the breakaway torque that actual torque arm length is exactly worm gear case.Because jack is exported relative to worm gear case
The distance of axle does not change, and actual torque arm length will not change because of the rotation of the arm of force, and test result is intuitively accurate.
As shown in Fig. 2 worm gear case mounting bracket 1 is made up of base 11 and installing plate 12.Base 11 is fixed on the ground, is installed
Plate 12 and base 11 are bolted, and are changed different installing plates 11, are gone for different worm gear cases different with regulation
Height.
As shown in figure 3, the arm of force 4 is designed as arcwall face with the contact surface of push rod 6, and add at the torque arm length of Theoretical Design
Work graduation mark, push rod 6 is designed to cylindrical type with the contact jaw of the arm of force 4, and the one end of transition sleeve 8 is threadedly coupled with pull pressure sensor 7,
The other end is designed to tubbiness, on the shell for being enclosed on jack 9.
Worm screw is installed on the worm gear pole axle of worm gear case 2 and rotates instruction device 3, the worm screw rotate instruction device 3 with
With worm shaft, instruction device is rotated with identical or different worm screw to different worm gear cases, for adjusting or observing
The rotation of worm shaft, to adjust the corner of worm-gear case output shaft, or whether observation worm gear pole rotates.
In the present invention, it is preferred to, with source of the gas type or hydraulic jack, loading is convenient, particularly with high pulling torque
Test.Pressure is counted accurately, and can show record data automatically.The rotation of the arm of force to the torque arm length of practical function not
Influence, it is not necessary to consider the influence at arm of force inclination angle, data result is more accurate.It is accurate that whole test system is applicable convenient, data.
