2．  Roller Wear TesterComponent Overview

4.1 Power System: Composed of a synchronous motor and a gear transmission, installed within the protective cover on the left side of the machine. The synchronous motor drives the rotation of the roller筒 via the gear transmission.

4.2 Roller Tube: Used for adhering sandpaper, with a diameter150mmThe roller and fixed bracket assembly features three horizontal stripe markings, indicating the adhesive placement for double-sided tape.

4.3 Transverse specimen driving unit: Guided by a screw thread rod19Sliding Block Nut18Rod, Guide Bar17Arm (without Chinese content)16) as well as "0Hammer assembly,0Hammer as the base hammer.

4.4 Sample Clamp: Guided sleeve11)、Tightening Fixture4)、Sample Positioning Screw10Small Transmission Worm Gears5and spare weights7）（8）（9Used for the fixation of weights and holding samples for various functions.

4.5 Gear rack and small drive gear assembly for sample rotation: Composed of a small gear and a gear rack. To achieve rotational movement of the sample during lateral movement, or non-rotational movement.

4.6 Automatic shutdown system after testing: with mobile roller (12Hinge Cover15The proximity switch, located on the protective cover to the right, is assembled. At the beginning of the test, the action of placing the sample on the roller is executed, when the roller is moved (12Roll to the right, then the proximity switch automatically shuts off the drive motor, and the specimen holder stops moving.

4.7 Dust Collector: Assembled bracket23) and vacuum cleaner hose parts26Composed of. Mainly used for cleaning rubber dust adhered to the rotating roller cylinder and collecting ground rubber particles.

4.8 Reset Rod: Reset rod14The function is to slide the sample holder back to its starting position after the test is completed. To achieve this action, the holder must first be folded backward, which allows the nut on the sliding block to disconnect from the driving screw.

4.9 Sandpaper: Sandpaper for60Manufactured from alumina with a grain size of... Width of...400mm, Length:437mmAverage thickness is:1mm。
