Abstract

And: the acquisition relates to the production and testing of gusipichnyh mappies and brings the test load to operational. In the base 1 there is a bath for abrasive, and to the side walls of the base two double-arm levers 2 are attached, which are connected with power springs 4 with a long arm and with a short arm with a tested chain of links 3. The middle link of the chain is connected with inertial mass 6. With crank 10, which is rotated by a power drive, the inertial mass is swinging and, through it, the test subject. The magnitude of the displacement of the inertial mass 6 determines the magnitude of the angular displacement of the hinges, and the tension force of the springs 4 causes the magnitude of the radial load on them. 1 il.

The invention relates to the field of: - production and testing of tracked vehicles.

The purpose of the invention is to approximate the test load to the operational one.

The drawing shows the stand (without a drive).

(The tendency consists of the base I, in which a bath is made for filling with abrasive. To the side walls of the base of the cross there are 2 two shoulders 2 levers 2. Each lever is connected to the test chain of 3 links with a short chain arm. the test chain 5 is associated with an inertial mass 6, which is connected to the load spring 7. To adjust the outgoing (a single position of the inertial mass is provided with a screw 8. The inertial mass through the swing rod 9 is connected to the curvature 10 of the link mechanism and the actuator for controlling the tension force of the test stand is equipped with a Dean caterpillars .mometricheskim device 11, and for kont- ro.- |. for the number of load cycles - momentum counter 12.

(lend works as follows.

When crank 10 starts to drive from a power drive, rod 9 starts to make a return movement and swing inertial mass 6. The more
