Abstract
The present invention relates to a mechanical transmission mechanism of output displacement or torque, which comprises a wheel sleeve. The left end of the wheel sleeve is provided with a moving shaft, the right end of the wheel sleeve is provided with a fixing shaft, the moving shaft is arranged in the wheel sleeve by a bearing and a bearing positioning clamping ring, and therefore, the moving shaft can move and rotate in a left direction and a right direction. The middle part of the wheel sleeve is provided with three springs, three top pins and three rollers, the springs, the top pins and the rollers ensure that the moving shaft rotates according to only one direction and moves with definite distance in the left direction and the right direction in the wheel sleeve, and a damping spring causes the movement and the rotation of the moving shaft to be kept stable and reduces inertia. Two bumping posts embedded on the bottom surface of the moving shaft contact two bumping posts embedded at the left end of the fixing shaft, and therefore, when the moving shaft and the fixing shaft rotate together, the force of the fixing shaft can be transferred to the moving shaft, and synchronous rotation is kept. The left end of the fixing shaft is arranged on the moving shaft by a centering rod and the bearing, and therefore, the concentricity, the displacement and the torque precision of the fixing shaft and the moving shaft can be kept. The mechanical transmission mechanism of output displacement or torque can simultaneously achieve various experiment functions of stretching, compressing (or upsetting), twisting, combining, etc.

Fig. 2 is that the A-A of Fig. 1 is to figure;
Fig. 3 is that the B-B of Fig. 1 is to figure.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, formation of the present invention is: a wheel cover 1 is arranged, and wheel cover 1 left end is adorned a shifting axle 2, stationary shaft 3 of right-hand member assembling.Shifting axle 2 is by bearing holder (housing, cover) 5, shifting axle bearing 4a, bearing gland 8, screw 6a on the shifting axle bearing gland is assemblied on the wheel cover 1 in left side, the endoporus of shifting axle 2 right-hand members has screw thread 16a, be meshed with the outer round thread 16b at stationary shaft 3 middle parts, and by stationary shaft hoop bearing 4b and bearing location snap ring 7, be fitted in the wheel cover 1, assurance shifting axle 2 can be realized move left and right and rotation in wheel cover 1; Three springs 19, three ejector pins 20 and three rollers 18 are arranged at shifting axle 2 middle parts, 10 li a damping spring 11 is installed at ring groove, have on its right side on the bottom surface, right side of endoporus of screw thread 16a to be embedded with two shelves posts 21, be embedded with two shelves posts 22 at stationary shaft 3 left ends.Wheel cover 1 left end is equipped with a dust ring 9.
The left end of shifting axle 2 is displacement or the output terminal that reverses, can link to each other with other parts by shifting axle left side keyway 13a or other form (as shaft coupling) of its left end.
Stationary shaft 3 right-hand members are fixed on the right side of wheel cover 1 by screw 6b and the bearing gland 14 on end bearing 4c, stationary shaft right side inboard bearing 4e bearing setscrew nut 15, outer end, the stationary shaft right side bearing gland outside the stationary shaft right side; The left end of stationary shaft 3 is fitted in shifting axle by centering bar 12 and stationary shaft left side bearing 4d, makes stationary shaft 3 and shifting axle 2 keep concentric.
The right-hand member of stationary shaft 3 is input ends of external force, links to each other with power source by stationary shaft right side keyway 13b or other form (as shaft coupling).
Monolithic wheel cover 1 is fixed on needed position by screw 17 or other form.
Example 1: the left end of shifting axle 2 links to each other with specimen holder by shifting axle left side keyway 13a, and the anchor clamps of the sample other end are fixed, and the right-hand member of stationary shaft 3 passes through stationary shaft right side keyway 13b and links to each other with motor, just can stretch, compression or twisting test.
During test, according to the needs of dissimilar tests, the relative position of shifting axle 2 and stationary shaft 3 is adjusted in the rotation of the rotating band moving axis 3 by motor, carries out different tests.When stationary shaft 3 turned clockwise, because the engagement of shifting axle inner hole thread 16a, stationary shaft external thread 16b, shifting axle 2 was toward moving left, and when being rotated clockwise to the limit, shifting axle 2 is blocked by left-hand axis bearing sleeve 5, can not continue toward moving left; When stationary shaft 3 is rotated counterclockwise, because the engagement of shifting axle inner hole thread 16a, stationary shaft external thread 16b, shifting axle 2 moves right, after rotating to certain position, the bumping post 21 of shifting axle 2 contacts with the bumping post 22 of stationary shaft, because the position of stationary shaft 3 can not be moved, shifting axle 2 can not continue toward moving right, can only be rotated counterclockwise jointly with stationary shaft 3 and oil motor, can do twisting test this moment; When shifting axle 2 and stationary shaft 3 are in relative position between above-mentioned two kinds of positions, can compress or tension test.
Example 2: when the present invention is applied on the heat simulating tester, can realizes drawing and turn round composite testing.
When the left end of sample provides pulling force, and the right-hand member of sample links to each other by the left end of anchor clamps with shifting axle 2, and shifting axle is in the low order end position.(provide power by motor or oil motor) when stationary shaft 3 is rotated counterclockwise, the left end of sample provides pulling force, and at this moment, sample just is subjected to the compound action of pulling force and torsion, has realized drawing turning round composite testing.
