Drawings
The invention is described in further detail below with reference to the drawings and the implementation.
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a schematic diagram of another embodiment of the present invention.
In the figure: 1. eccentric cam, 2, experimental shaft, 3, left support, 4, the oil blanket that awaits measuring, 5, medium cavity 6, spiral groove axle, 7, spiral groove, 8, guide pillar, 9, compress tightly the post, 10, compression spring, 11, right support, 12, base.
Detailed Description
A device for realizing reciprocating and rotary motion of oil seal experiment, refer to fig. 1, be fixed with left support 3 and right support 11 respectively in the both sides of base 12, the left end of experimental shaft 2 passes through the bearing and installs in left support 3, the experimental shaft 2 terminal surface that passes left support 3 is tangent with eccentric cam 1 outer cylinder laminating, eccentric hole axis and the external power axis coincidence of eccentric cam 1, external power drives eccentric cam 1 rotatory, the right-hand member of experimental shaft 2 is equipped with helical groove 7 outward, the right side of experimental shaft 2 is connected with the compression post 9 that is equipped with the boss, the right-hand member that compresses tightly post 9 passes through the bearing and installs in right support 11 and fix through the nut, the cover is equipped with compression spring 10 on the compression post 9 between boss and right support 11, the head of the guide pillar 8 of fixing on base 12 stretches into in the helical groove 7, the inboard of left support 3 is equipped with medium cavity 5, be equipped with the oil blanket that is used for installing the oil blanket 4 that awaits measuring on the medium cavity 5, experimental shaft 2 passes and installs the oil blanket 4 that awaits measuring on the oil blanket bottom hole.
In order to adapt to the requirements of different tests, referring to fig. 2, a spiral groove 7 is arranged on a spiral groove shaft 6, and the spiral groove shaft 6 is arranged between the experiment shaft 2 and a compression column 9.
The external power drives the eccentric cam 1 to rotate, the rotating motion of the eccentric cam 1 is converted into the reciprocating motion of the experimental shaft 2, the eccentric size of the eccentric cam 1 is the reciprocating motion stroke of the experimental shaft 2, the eccentric cam rotates for 1 week, and the experimental shaft 2 reciprocates for 1 time. Thus, the eccentric size and the rotating speed of the eccentric cam 1 can be calculated according to the size requirements of experimental travel and speed. The compression spring on the compression column 9 at the right end of the experimental shaft 2 can ensure that the outer cylindrical surface of the eccentric cam 1 is reliably attached to the left end surface of the experimental shaft 2. The left end of the experimental shaft 2 is concentrically arranged in the left support through a bearing, so that the experimental shaft 2 can move freely. The medium chamber 5 is fixed on the inner side of the left support 3 through screws, the experimental shaft 2 passes through an oil seal 4 to be tested which is arranged on an oil seal bottom hole of the medium chamber 5, and a cavity in the medium chamber 5 is used for filling liquid in experiments. The groove of the spiral groove 7 of the spiral groove shaft 6 is tangent to the head of the guide post 8, when the experiment shaft 2 drives the spiral groove shaft 6 to reciprocate, the spiral groove 7 is guided by the fixed guide post 8 to realize rotary motion, and if the reciprocating motion stroke of the experiment 2 is known, namely the number of turns of the experiment shaft 2 required to rotate for 1 week by rotating the eccentric cam 1 is known, the lead size of the spiral groove shaft 6 can be obtained through calculation. In addition, we can change the rotation direction of the spiral groove shaft 6 by changing the rotation direction of the spiral groove 7 with the spiral groove shaft 6.
