TPG100-8 is a planar enveloping toroidal worm reducer. The installation process needs to focus on core links such as preliminary preparation, precise positioning and fixation, shaft connection and alignment, and lubrication debugging to ensure its transmission stability and service life. The specific steps are as follows:
1. Preparation before installation
(1) Equipment and document verification: First confirm that the model, power and other parameters of TPG100-8 match the actual working conditions, check that the shell, worm gear tooth surface, etc. are free of cracks and rust, and that the contact spots on the tooth surface meet the standards. At the same time, check whether technical documents such as instructions and assembly drawings are complete. Subsequent installation must strictly refer to the document requirements.
(2) Preparation of tools and auxiliary materials: Prepare levels, torque wrenches, micrometers, wrenches and other tools, and ensure that the tools are intact and accurate; in terms of auxiliary materials, prepare suitable lubricating oil (usually ISO VG220 extreme pressure gear oil), sealing pads, anchor bolts, etc. If the installation environment is special, you need to prepare anti-vibration pads.
(3) Installation location planning: Choose a flat, solid, and well-ventilated installation location to ensure it can withstand the operating load of the equipment and facilitate subsequent refueling, oil drainage, and maintenance. Clean the installation area of debris, check that the size and depth of the anchor bolt holes match the base of the reducer, and prepare epoxy resin for sealing in the waterproof area.
2. Hoisting and positioning
(1) Standardized hoisting: Hoist with the help of a crane or forklift. The lifting points must be aligned with the lifting lugs of the reducer or reserved hoisting holes. It is strictly prohibited to bundle the shell at will. Keep it steady when hoisting, avoid violent shaking, and prevent damage to internal gears, bearings and other components. When lowering, the height is slightly higher than the installation position, and slowly fall to the predetermined position.
(2) Preliminary positioning: Align the reducer with the anchor bolt holes and place anti-shock pads on the base to reduce operating impact. There is no need to tighten the bolts completely at this time, leaving room for adjustment for subsequent alignment.
3. Fixing and alignment
(1) Horizontal calibration: Use a level meter to measure the levelness at multiple positions (such as diagonals) of the reducer base to ensure that the deviation is ≤0.1/1000. If it does not meet the standard, correct it by adjusting the thickness of the gasket. Do not use brute force to pry the equipment body.
(2) Tighten the anchor bolts: Use the diagonal cross-step tightening method, first tighten evenly to 50% of the pre-tightening force, and then gradually increase the force to the rated value to ensure uniform stress on the base. After tightening the bolts, recheck the levelness to prevent the equipment from shifting during the tightening process.
4. Shaft connection
(1) Cleaning and inspection: Clean the keyway of the input shaft and output shaft and the coupling contact surface, remove oil stains and burrs to avoid affecting the connection accuracy and transmission effect, and check whether the coupling is intact.
(2) Precise alignment: When connecting the input shaft to the prime mover and the output shaft to the working machine, elastic couplings are preferred. If the output shaft requires heavy-duty transmission, a gear coupling can be used. Use the double-meter method or laser alignment instrument to check to ensure that the parallel deviation is ≤0.05mm, the angular deviation is ≤0.02mm/m, and the coupling end face gap is maintained at 0.05 - 0.10mm.
(3) Tighten the connection: Use a torque wrench to tighten the coupling bolts according to the manufacturer's recommended torque value to avoid vibration or abnormal noise during operation due to loose bolts. After installation, you can turn the coupling lightly to confirm that the rotation is flexible and free of jamming.
5. Lubrication and sealing inspection
(1) Add lubricating oil: Open the oil filling port and inject the appropriate lubricating oil. The amount of oil added is bounded by the center line of the oil mark or reaches 2/3 of the viewing window. Do not add too much or too little. Too much will increase power consumption and increase the oil temperature. Too little will not ensure lubrication and cause component wear.
Seal inspection: Check oil seals, bearing end covers and other sealing parts to ensure that the seals are intact and undamaged. An appropriate sealant can be applied to the joint surface to prevent oil leakage during operation. At the same time, clean the oil plug and oil mark to facilitate subsequent checking of the oil level.
6. Post-installation debugging and acceptance
(1) No-load test run: Start the equipment for no-load test, run for no less than 30 minutes, observe whether the operation is stable, and whether there is any sharp noise or abnormal vibration. Monitor the bearing temperature to ensure that the temperature rise is ≤40°C and the shell temperature does not exceed 70°C. If there is any abnormality, stop the machine immediately for investigation.
