Are there software tools for calibrating large-scale equipment such as drying ovens?
Thread Content
It is very difficult and challenging to align such large-scale equipment, and there are no simulation or alignment software available? Or there are good debugging equipment and methods that can accelerate the tuning process; I would appreciate it if experts could share their insights.
Should it be cylinder alignment or coupling alignment? For cylinder alignment, a laser aligner can be used.
Cylinder alignment is easier; coupling alignment is a bit simpler as well. Today I watched the equipment technicians adjust the clearance between the large and small gears; adjusting the four idlers back and forth while also taking into account the movement of the cylinder barrel made it difficult to resolve the issue quickly. I’m looking for a quick solution or software for simulated adjustment that can provide suggestions for adjustments based on input parameters
The meshing clearance between the large gear and the small gear is determined based on the lateral clearance, which is 2.1 MM; the actual value of the top clearance is then calculated accordingly. The large gear is aligned using the highest point of its radial runout, and the clearances on the top and sides of the teeth must be equal. The large gear is measured in eight equal sections, with the lateral clearance at each point ranging from 1.8 to 2.6 MM. The errors on the inner and outer sides should not exceed 0.15 MM, and the measured values must be symmetrical, without any bias to one side. Adjustments are made according to the maximum value specified in the technical requirements; once the small gear is fixed, the large gear is rotated to measure the 8 points to determine whether they meet the requirements.
Thank you for the answer. I’m not from the equipment field; I’m just starting to learn *. The current situation is theory combined with experience; there are no other good options. Learn slowly* and explore gradually
When installing the large gear in the cylinder, follow the markings provided by the manufacturer; tighten the connecting bolts. Use a dial indicator to measure the radial runout of the large gear, and adjust it using set screws until it meets the manufacturer’s technical requirements or specifications. Find the maximum radial runout.
Follow the procedure by installing the large gear ring first, then the small gear ring. Installation and alignment of the large gear ring: Before installation, the tooth surfaces, the mating surfaces of the semi-circular gears, as well as the areas where the teeth connect to the spring plates must be cleaned thoroughly; there should be no oil or debris present ； Pre-assemble the large gear ring interface on the ground, and inspect its tooth profile, addendum diameter, pitch diameter, and tooth surface condition; also check the clearance at the joint surfaces ； Mark the position of the large gear ring on the cylinder, and grind the weld at the location of the spring plate smooth so that the cylinder and the spring plate can make tight contact ； Install the spring plate on the ring gear at ground level, paying attention to the direction of rotation ； Lift into place using a crane ； Use the special tool for installing the large gear ring to position it equally at four points around the circumference of the large gear. Weld the feet of the support frame to the kiln cylinder in order to initially align the large gear, and then rotate the kiln to determine the allowable radial runout of the large gear ring: 1.5 mm ； Allowable end face runout of the large gear ring: 1.0mm ； After passing the inspection, press the spring plate in place and weld it. The spring plate must be firmly bonded to the cylinder, and welding should be carried out in a specific sequence. After welding, measure the radial runout and end face runout of the large gear again. When installing the pinion, allowance for the expansion of the gear wheel must be provided as per design requirements, and its inclination shall be determined ； Adjust and measure the tooth tip clearance of the large and small gears; this clearance can be taken as 0.25M + (2–3) millimeters, where M is the gear module ； The contact area between the meshing tooth surfaces of the gears shall be at least 50% along the tooth length and at least 40% along the tooth height ；
Thank you for your answer; it’s very detailed.
