A linear vibrating screen is a type of vibrating screen that uses a linear vibration to separate and sort materials. The screen deck is composed of a mesh or perforated plate, and the vibration is generated by an eccentric shaft or motor that drives the deck. The material is fed onto the deck, and as it vibrates, the material is separated into different sizes and grades based on the mesh size. The linear motion of the deck helps to move the material along the screen, ensuring that all of the material is sorted accurately. Linear vibrating screens are commonly used in a variety of industries, including mining, construction, food processing, and chemical production, to separate and sort materials.

The working principle of a linear vibrating screen is based on the vibration of the screen deck. The deck is made of a mesh or perforated plate and is vibrated by an eccentric shaft or motor-driven eccentric mass. When the deck vibrates, the material is separated into different sizes based on the mesh size, with the larger particles being separated out first and the smaller particles passing through to the next deck, if present.

The vibration of the deck is generated by the movement of the eccentric mass, which is driven by the motor. The vibration causes the material to move along the screen, separating the particles based on size. The linear motion of the deck helps to evenly distribute the material across the screen, ensuring that all of the material is sorted accurately.

In summary, the working principle of a linear vibrating screen is based on the vibration of the screen deck caused by an eccentric shaft or motor-driven eccentric mass, which separates the material into different sizes based on the mesh size. The linear motion of the deck helps to distribute the material evenly across the screen for accurate sorting.

The clutch is a major assembly in the tractor drive train. When the tractor starts, the high-speed rotating engine is smoothly connected with the stationary drive train through the friction between the active part and the driven part of the clutch to ensure the vehicle starts smoothly. In the long-term use of tractor clutches, the wear and tear of parts is unavoidable, and the replacement of parts has become the main work of clutch repair. The quality of assembly and adjustment technology after parts replacement determines the service life of the clutch after repair. Next, we will mainly take a certain brand of 25 type tractor clutch as an example to introduce the assembly and adjustment points of single-plate dry clutch.

Tractor clutch assembly

1. Assembly of release bearing assembly

The clutch release bearing is installed between the clutch and the transmission, and the release bearing seat is installed on the tubular extension of the first shaft bearing cover of the transmission. The shoulder of the release bearing always touches the release fork through the return spring and retreats to the final position. Keep a clearance of 2.5 mm from the release lever. There should be an interference of 0.03 mm when the separation bearing seat is installed. During installation, the inner cavity of the bearing and bearing seat should be filled with butter, and there is no place for oiling the bearing at ordinary times.

2. Assembly of clutch pressure plate assembly

The assembly of the clutch pressure plate assembly is to assemble the pressure plate, spring, clutch cover and separation mechanism together, and the spring must be compressed before proceeding. The spring can be pressurized by means of mechanical pressurization or hydraulic pressurization by self-made simple support, and also can be pressurized on a radial drilling machine.

(1) Put the pressure plate on the platform, and place a circular backing plate with a thickness of 10 mm and an outer diameter slightly smaller than the diameter of the pressure plate under the pressure plate, or place three small nuts of the same thickness on it.

(2) Place the swing block, release lever, release lever adjustment screw and pin on the inner side of the boss of the pressure plate in sequence, put the spring on the boss of the cross-shaped spring seat, and align the clutch cover with the transmission plate in place Put it on the spring, make the 4 adjusting screws pass through the corresponding holes on the clutch cover, and straighten the transmission plate so that the unriveted end is aligned with the screw hole on the pressure plate.

(3) Pressurize the spring on the clutch cover, and compress the spring by more than 10 mm. At this time, screw on the adjusting nuts one by one, and then fix the transmission disc bolts together with the transmission disc bolt seats in the screw holes of the pressure plate, and punch riveting Bolt seat.

3. Installation of driven plate assembly and pressure plate assembly on the flywheel

This installation is mainly about the centering of the driven disc assembly, so during installation, the clutch shaft (namely the first shaft) can be used as the mandrel, or an optical shaft can be used instead. Insert the center of the driven disc with the optical shaft, insert it into the flywheel bearing hole, then install the pressure plate assembly to the plane of the flywheel, and tighten it diagonally with six M8×20 bolts. With the optical shaft pulled out, the center of the driven disc is correctly fixed on the flywheel.

Speaking of crane slewing bearing wear, the inspection methods are mainly divided into rotary method and tilt method. As for which inspection method to choose, it is mainly determined whether to use the tilt method or the rotary method to measure the bearing wear according to the counterweight configuration of the crane.

The basic premise of the slewing method is that the bearing can always be tilted fully forward in the direction of the boom, and that this tilt follows the rotation of the crane.

1. There is no load on the hook, tighten the hook to a higher position, release the boom to the horizontal position (note that the boom does not collide with the platform facilities when turning horizontally) or lower the boom to the maximum limit position (the minimum level of the boom angle);

2. Use the base of the magnetic dial indicator to fix it to the position of the crane base, the magnetic pointer points to the clean and rust-free horizontal processing surface of the upper rotary disc, and adjust the pointer to the zero state (the reference 0 position point is established at this time);

3. Slowly turn the crane 360 degrees, record the reading of the pointer every 45 degrees in the dynamic state, and confirm that the pointer reading should return to zero when the crane turns 360 degrees and returns to the initial position (record the elegant data when it does not return to the zero position value); for every four positions of the crane at intervals of 90 degrees, repeat the operation according to the above step 3, and record a total of 32 data in the four positions, and then organize them into a table for analysis.

The maximum permissible deviation is required to be 1.7mm, and the measurement accuracy of the dial indicator measuring instrument is at least +0.05mm or more.

The premise of the tilt method is that the bearing can be fully tilted forward and backward by using the counterweight, boom luffing or jack. The purpose is to measure the total clearance between the inner raceway of the bearing and the rolling elements without causing obvious moment of elastic deformation on the bearing.
