Whether the assembly of agricultural machinery parts is properly related to the length of time the agricultural machinery runs smoothly, in order to ensure the long-term use of agricultural machinery is good, the assembly of agricultural machinery parts must be done. Here are some tips for assembling agricultural machinery parts.
Cylinder head gasket
If there are oil holes, they must be aligned with the corresponding oil passage holes on the machine body and the cylinder head so as to avoid friction caused by the oil cut-off on the cylinder valve cover. No oil passage holes and positive and negative shapes are the same, determined by the material of the cylinder head: For the aluminum alloy cylinder head, the flange of the cylinder head should face toward the cylinder; for the cast iron cylinder cover, the flange of the cylinder head should face the cylinder head. .
Pistons and piston rings
Pistons marked with an upward arrow on the top shall be installed in the direction specified by the mark; if not marked, small cavities near the top of the piston vortex pit or pit shall be directed towards the injector side to ensure uniform gas mixing. When assembling the piston ring, the top shall be marked with UP or UP and shall face upwards; the undistributed torsion ring at the top shall have its inner circle cut or chamfered downward; the chrome-plated ring (the shell shall be shiny) shall be installed on the first track. Piston ring groove, each ring opening should be staggered 120 ~ 180 degrees to ensure its sealing effect.
Linkage and connecting rod cover. The connecting rod of the horizontal diesel engine is divided by 45 degrees, and the section should be face down to improve the stress of the connecting rod bolt. The connecting rod cover and the connecting rod are paired and processed, and the matching marks should be on the same side during assembly to ensure that the roundness and cylindricity of the connecting rod bearings meet the specified requirements.
Main bearing caps, bearings, bushings
Both the main bearing cover and the body bearing seat are paired boring processing. They should be paired with the pairing mark and must not be interchanged or changed in assembly direction so as not to damage the coaxiality and dimensional accuracy of the main bearing housing hole. The bearing bushes or bushings with oil holes should be aligned with the corresponding oil hole on the bearing seat and the bushing hole to ensure the smoothness of the oil path.
Transmission shaft and drive chain
The transmission forks at both ends of the transmission shaft should be in the same plane so as to avoid torsional vibration and damage of the transmission components. If the transmission chain adopts spring clips, the direction of the open end should be opposite to that of the chain so as to avoid falling off due to impact during movement.
Drive wheel
The drive wheel is marked with an upward arrow and it should be pointed at the direction of rotation of the tire when it is advanced; when there is no mark, the drive wheel is seen from the back of the locomotive, and the top of its figure-shaped or herringbone pattern should face upwards.
Cylinder head bolt
If one end of a bolt is a coarse thread and the other a fine thread, the coarse thread end should be screwed into the body; if the end of the bolt is a fine tooth, the shorter end should be screwed into the body to ensure Press the cylinder head tightly.
Oil pump and injection pump. If the oil is of the planetary rotor type, the outer rotor should be chamfered towards the pump body so that the oil does not circulate in the pump and the pump oil pressure is reduced. The crescent-shaped positioning groove on the fuel injection nozzle plug sleeve should be aligned with the positioning hole on the pump body. The mark (or oil return groove) on the plunger should be installed upward to avoid causing no oil supply or diesel engine coaster.
Vertical Type Dental Milling Machine
Vertical Type Dental Milling Machine CAD CAM Dental Milling Machine is the champion in dental field. The dental milling provides dynamic flexibility with a built-in. This provides the user with the agility to produce a wide range of dental restoration components based on demand -- including crowns, bridges, abutments, implant-carried resorations. Plus, the Vertical Type Dental Milling Machine accommodates and supurbly machines a variety of dental materials including titanium, chrome-cobalt, zirconium and more! The Vertical Type Dental Milling Machine was developed specifically and exclusively for dental milling applications. All specifications from machine size to performance were designed for the efficient handling and milling of dental blanks (or material pucks). The blank is milled in the absolute center of the machine ensuring optimal cutting force. High performance servo and torque motors deliver superior machining dynamics and speed. the the CNC dental milling machine will can satisfy all your need.
