1、 Source margin optimization reduces ineffective grinding hours Strictly control the common normal clearance of the hot rolling gear, compress the single-sided clearance of the grinding gear from the conventional 0.2mm to 0.12-0.15mm, and directly reduce the grinding time by 30%. The heat treatment adopts fixture assisted quenching+pre deformation compensation to control the deformation of
1、 Existing efficiency improvement foundation and current level By 2025, the average yield rate of precision reducer gear grinding in China has reached 98.7%, and the average grinding time for a single reducer gear has been reduced from 4.8 hours in 2024 to 4.1 hours, with an efficiency improvement of 14.6%. Top enterprises have achieved an 18% reduction in single tooth grinding time and a 2
1、 Pre prevention and control measures before adjustment Eliminate soft foot hazards: Use a feeler gauge to check the contact between the reducer, motor/load base, and foundation. All feet should not be suspended, and the single foot gap should be ≤ 0.03mm to avoid force rebound after adjustment. Basic accuracy verification: Use a precision level to measure the levelness of the gearbox body,
1、 Safety and material preparation before disassembly and assembly Cut off the power supply of the reducer and supporting motor, hang a warning sign prohibiting closing, remove the motor wiring and make proper markings. Completely remove external loads such as couplings and sprockets from the output shaft end to avoid deformation of the shaft system during disassembly. Prepare specialized
1、 Fault in input side power connection components Input shaft flat key/spline failure: The motor is idling but the input shaft of the reducer is not synchronized, resulting in obvious idle clearance on the input side and direct power interruption. Coupling connection failure: elastic body fracture, bolt detachment, motor rotation but gearbox input shaft does not rotate at all, no power tran
1、 Core power limit boundary General industry consensus: Natural cooling is only suitable for light load intermittent working conditions of ≤ 5kW. If the power exceeds this limit, forced air cooling or water cooling devices must be installed. Range of machine base size adaptation: F37 and F47 machine base sizes (rated input power of 0.18~3kW) can fully meet the requirements of natural coolin
1、 Static accuracy verification Basic levelness meets the standard: Use a level with an accuracy of 0.02mm/m to detect the longitudinal and transverse levelness of the top of the box. Adjust the gasket to control the error ≤ 0.05mm/m, and there is no suspended gap between the base and the foundation. Axis alignment qualified: Use a dial gauge to measure the radial deviation between the input
1、 Basic Universal Subseries WPA type: integral box, input shaft at the bottom, horizontal foot installation, is the most widely used basic model in general scenarios. WPS type: Integrated enclosure with input shaft on top, suitable for special installation scenarios where input shaft space is limited. WPX type: integral box with output shaft facing downwards, suitable for equipment layou
