In figure: 1, eccentric cam, 2, experiment axis, 3, left support abutment, 4, oil sealing to be measured, 5, medium chamber 6, spiral groove shaft, 7,
Helicla flute, 8, guide post, 9, hold-down column, 10, compressed spring, 11, right support abutment, 12, pedestal.
Specific embodiment
It is a kind of to realize reciprocal and rotary motion device for oil sealing experiment, it is in the two sides of pedestal 12 point referring to Fig.1
It is not fixed with left support abutment 3 and right support abutment 11, the left end of experiment axis 2 is mounted in left support abutment 3 by bearing, across left support abutment 3
Experiment 2 end face of axis is bonded tangent, the eccentric axially bored line and external impetus axis weight of eccentric cam 1 with 1 external cylindrical surface of eccentric cam
Close, external impetus drives eccentric cam 1 to rotate, and the right end of experiment axis 2 is externally provided with helicla flute 7, test the right side of axis 2 with equipped with convex
The hold-down column 9 of platform connects, and the right end of hold-down column 9 is mounted in right support abutment 11 by bearing and is positioned by nut, boss and the right side
It is set with compressed spring 10 on hold-down column 9 between support 11, the head for the guide post 8 being fixed on pedestal 12 extend into helicla flute 7
Interior, the inside of left support abutment 3 is equipped with medium chamber 5, and medium chamber 5 is equipped with the oil sealing bottom outlet for installing oil sealing 4 to be measured, experiment
Axis 2 is passed through oil sealing 4 to be measured on oil sealing bottom outlet.
In order to adapt to the needs of different tests, referring to Fig. 2, helicla flute 7 is arranged on spiral groove shaft 6, and spiral groove shaft 6 is mounted on
It tests between axis 2 and hold-down column 9.
External impetus drives eccentric cam 1 to rotate, and is converted to the reciprocal of experiment axis 2 by the rotary motion of eccentric cam 1
Movement, the eccentric size of eccentric cam 1 is exactly to test the size of the reciprocating stroke of axis 2, and eccentric cam rotates 1 week, experiment
Axis 2 moves back and forth 1 time.So the eccentric size of eccentric cam 1 can be calculated according to experiment stroke and the size requirements of speed
And rotation speed.Compressed spring on the hold-down column 9 of the right end of experiment axis 2 can guarantee the outer circle cylindrical surface of eccentric cam 1
It is reliably bonded with the left side of experiment axis 2.Experiment 2 left end of axis is concentrically mounted in left support abutment by bearing, guarantees experiment axis 2
Movement is freely.Medium chamber 5 is fixed by screws in 3 inside of left support abutment, and experiment axis 2 is passed through 5 oil sealing bottom of medium chamber
Oil sealing to be measured 4 on hole, liquid when 5 internal cavities of medium chamber are used to fill experiment.The slot of the helicla flute 7 of spiral groove shaft 6 with
The head of guide post 8 is tangent, when experiment axis 2 drives spiral groove shaft 6 to move reciprocatingly, passes through fixed 8 lead screw slot 7 of guide post
Rotary motion is realized, if the reciprocating stroke of experiment 2 is it is known that i.e. eccentric cam 1 rotates the circle that 1 week experiment axis 2 need to rotate
Number is it is known that the lead size of so spiral groove shaft 6 can be by being calculated.In addition we can be by changing band helicla flute
The rotation direction of the helicla flute 7 of axis 6 changes the direction of rotation of spiral groove shaft 6.
