Abstract

This invention relates to the field of abrasive wear testing. The aim of the invention is to increase the reliability of the results by ensuring uniform wear of the test sample of the material. When the holder 2 of the abrasive cylinder 4 rotates, the test sample 5 receives a rotational-translational movement (along the generator cylinder) by gear racks 6 and 7 and gears 9. The gear ratio of the mechanism connecting the holder 2 and the driving screw 8 is selected based on the condition of uniform wear sample 5. 1 Il.

The invention relates to the testing of abrasive wear materials.

The aim of the invention is to increase the reliability of the results by ensuring uniform wear of the test sample of the material.

The figure shows a device for testing materials for abrasive wear.

The device comprises a housing 1, an abrasive cylinder 4, and loads the sample 5. Rotation from the drive is transmitted to the spindle screw 8, which moves the gear rack 7. At the same time, using a brush 5 and 9, rotating and moving along the fixed rail 6, the holder 3 and the subject Sample 5 performs a rotational-translational movement relative to the abrasive cylinder 4.

. ... The parameters of the indicated movement were circled 2 and 3, respectively, of the abrasive cyt 5, changed by transferring the indra 4 and the test sample 5, the mathematics between the holder 2 and the suspension shaft, the loading unit (not shown), primer (not shown ) rotation of the holder 2. The device is equipped with a toothed rack 6, fixed in the case 1 parallel to the axis of the horner 2, mounted in the case with the possibility of moving parallel to the toothed rack 6 by the second toothed rack 7 with the lead screw 8, gear 9, gear in engagement with racks 6 and 7 and coaxially with the holder 3 of the test cylinder 20 and the test specimen, unit 5, and the transmission mechanism (not loading the sample and the abrasive cylinder and lokazan), kinematically linking the holder 2 and the lead screw 8. At ohm gear gear ratio

connecting holder 2 and spindle screw 8, chatted rail mounted in the housing is 1brano so that in one turn the abrasive parallel to the axis of the abrasive cylinder holder mounted in the housing can be moved parallel to the first toothed rack by a second toothed rail with the lead screw, gear, set the screw 8, the last step, the diameter of the gear 9.
